So what's your end goal?
How big is the big turbo and don't you think that a smaller turbo would be sufficient and more fun?

This turbo is a BNR s4, it is "the biggest small turbo" so im on the same track as you Anon

why not go for a small fast spooling turbo thats almost always in boost? especially in an FF car

Here is the link to my youtube if you guys want to see some progress I have made so far, right now im waiting on parts from corksport (tranny mount) and a catch can from damon motorsports to come in. Im heading up to AWD tuning in dallas Tx today, be back saturday with dyno event video.

https://www.youtube.com/channel/UCkbYj5vHhKrQGOJJ5GUmDMQ

The BNR s4 is a good choice for fun guys, it will hit peak boost at 3500-3600 RPMS, and is good for up to 450 hp and 450 Torque, The k04 turbo I had on there is too small and ran out of puff, It made 300 HP and 360 Torque before i started this build, I plan to gain 100 hp and 40 torque and thats tuned down since i dont want the block to explode.

Nice dude, what have you got right now for suspension and exhaust? Those are the two mods I'm looking at next and I've been really curious for input; I want to go cheap on my coilovers kinda cause I basically just want to not feel monster truck status, go down a couple inches but my one buddy is telling me don't cheap out on them. What do you think? Also is your k20 blown or just upgrading it for the power and selling the k20?

according to the stats, the thing comes on around 3250rpm and hits max torque at 4000rpm

honestly you would want somthing that comes into boost around 2800rpm and peaks at around 3800-4000 rpm that way you have more usable power and arnt bogging down when turning from stop signs or on tight twisties

according to the sizing info the extruder is 76mm which is going to produce a sizeable lag on the low end meaning that na cars will definitly get a huge jump on you from a dead stop

if anything you want somthing a little smaller and instead opt for lightweight flywheel, lightweight pulleys, lightweight wheels (RFP1) and any engine modification that will increase low end power and make for faster response

>>17150452
you cant even know how to do your own oil change fuck off

Its a k04 not a k20???? If you are in need of a k04 let me know, it IS NOT BLOWN i just want more boost, message me on the youtube mate. My suspension is stock, exhaust will be a 3 inch dump side exit for now, the build cost alot of money and im doing it in stages, this is the first one, and will get me to 400/400 easily

>>17150489
K04* my bad, I always forget parts names and get them mixed up with engine names and shit, too much mixing around in my brain.

>400hp FF
I don't see the point, but you do you.

Well the oil has been changed so there is that lol....why you so angry?

I need to build the block for over 400, meth, intake mani, turbo mani is the next stage, im not doing it all in one swing, turbo and my setup i can get to almost 500 but thats down the road.

>>17150505
The bnrs4 is a popular "big turbo" swap on the speed3, I'd say he's gonna be fine. The other one is a G-somethingsomething, probably the one I'll end up with when my K04 dies on me.

thanks for the info man, i am a complete newb, this is my first time doing any work like this on my car, like previous guys said, the BNRs4 is a popular upgrade path we shall see, hope I didnt go too big !

>>17150558
You'll be fine. If you don't mind, what have you done to be getting 300hp before your swap? I'm sitting at 300 whp with corksport catback, cobb sri, e85 mix and purple drank tune. Saying you're a newb...does this mean you haven't gotten the auto tech hpfp plunger thing, to increase your fp pressure? If so I'd do that immediately before anything.

Well you see, we can't spin out at 5mph with this set up. It'd be pretty good for you, now I think about it.

>>17150516
>>17150607
I don't know if any of you guys watch BoostedBoiz at all, but their 600hp EK hatch and 400hp Civic wagon look rad as fuck to me. Sure, they won't do good on a track, but they seem to be really fun on the streets.

I don't have any issue with it, 50 dollar stiffer rear motor mount and its solved. Weird.

>>17150444

>>17150651
>50 dollar stiffer rear motor mount and its solved
???
No.

>>17150655
???
Ya?? First hand experience trumps whatever meme shit you read furfag.

>>17150663
Why would a motor mount stop wheel spin?
>>17150647
When did I claim to be an expert?

>>17150670
If you're saying wheel spin, actual wheel spin it doesn't. Everything spins, some with varying degrees of it. It's not that much worse than a mustang launching would be. If you're talking torque steer wheel spin, the rmm completely eliminates it. I mean, you'd know about spinning tho I guess

>>17150682
>It's not that much worse than a mustang launching would be
Except when the mustang launches the weight transfers backwards and increases grip, when the MS3 launches the weight transfers backwards and decreases grip.
Hell, my fucking 50hp festiva spins the tires taking off if I give it a bit of throttle.

>>17150692
>Hell, my fucking 50hp festiva spins the tires taking off if I give it a bit of throttle
You mean if you dump the clutch at 6000rpm?

>>17150704
No, not dumping the clutch.

>>17150692
The rmm stops the engine from shifting so the energy being transfered isn't nearly as much with the original motor mount (thus the "stiffer" part comes into play) So the spin is pretty much eliminated. Use your brain.

>>17150704
the fag is right though. you're gonna be spinning hard as fuck.

>>17150722
>the motor mount will stop the 400hp from spinning the wheels
This is fucking hilarious

>>17150722
>Use your brain.

He's a retarded furry. He can't, or else he might realize how pathetic his really is and kill himself.

>>17150725
I've never had a fast car so I'm just a benchracer, but why doesn't that happen in vid related and such?
https://www.youtube.com/watch?v=_epjDOBCJP8&t=218s

>>17150730
I didn't say at 400hp. I'm not OP, yea it's gonna spin at 400hp. Spoilers: most cars do.

>>17150747
Yeah, even a fucking 50hp car does lmfao

>>17150730
believe it or not motor mounts are well known to stop WHEEL HOP on fwd cars which when doing off the line launches results in wheel spin

just keep in mind that its only from a dead stop and really only if you have the appropriate tire and suspension setup to coincide with the motor AND TRANSMISSION mounts obviously if you are riding the 2step on a moist day on and drop the clutch from a dead stop there is going to be wheel spin but if driven correctly you wont have much if any at all until you transition to the next gear and even then there wont be any torque steer

>>17150745
Skip to 3:40 btw, timetags in the URL don't fucking work on 4chan for some reason

>>17150745
You just posted rolling race pulls you dumb fuck.

>>17150758
Of course motor mounts will make a difference with wheel hop, but to say >>17150682 "the rmm completely eliminates it."
is absolutely fucking retarded

>>17150764
So?

>>17150745
Because they're racing from a roll

>>17150758
>>17150730
RETARD FIGHT

>>17150784
I either took the bait hard or you're too fucking dumb to be allowed to have a license.

>>17150777
no its not, did you come into this thread to argue about motor and transmission mounts?

have you even owned a fwd car that you put motor and transmission mounts in?

do you know the before and after?

>>17150785
If it was really that bad, it would spin hard at 40mph too, knowing it has 600hp.

>>17150433
>Yeah, even a fucking 50hp car does lmfao
You should probably get some new tires and stop driving a 20 year old shit box to compare it to a hot hatch lol.

>>17150808
No, he just came here to talk shit.

And he's right, 400hp in an FF car is useless.

>>17150805
No I just don't understand why it is so umbelievably important for the car to have good traction starting from a standstill if it can beat most sports cars from a roll.

>>17150808
>have you even owned a fwd car that you put motor and transmission mounts in?
I've changed out about 100 motor mounts, never for performance reasons though.
>>17150825
>who cares if it can't take off fast
Literally why are you trying to build a car if you can't take off fast

>>17150825
the dipshit pointed out you'll have wheel spin

he's right.

you said a motor mount would stop it.

you're wrong.

you then posted rolling race videos as proof and showed us you don't know what you're talking about.

ITT: People that know nothing about the MZR platform.

Props OP. Looks like a sick build. BNR S4 is the way to go.

>>17150840
so no you have never owned a fwd car that you then upgraded the motor and transmission mounts on, it really shows

also not everyone enjoys blowing up their car doing 6500rpm clutch dumps some people like to turn onto the freeway entrance ramp and floor it to 150mph

from the sound of it you are a mechanic who works on crappy cars all day and thinks he knows about the automotive performance sector despite not having any experience in it

>>17150840
It can take off fast, just not as fast as it would if it was RWD.
>>17150848
I'm not the motor mount guy neither the guy that is building the car.
I first replied when anon and dogfucker implied that there is no point in making 400hp if your car is FF. I thought I'd point out that there is a point because beating Mustangs, GTRs and Camaros in a shitbox is fun as fuck.

>Mrcummy gets his hourly BTFO
>by a retard in a leased automatic FRS of all people

He'll go cry to himself for a few hours then come back and shit up another thread, like clockwork.

>>17150857
refer to >>17150848
The motor mount being stiffer or solid will stop it from recoiling, compression, rebound over and over which will cause wheel hop.
That has nothing to do with wheel spin from the front tires being deweighted on take off, it will only stop it from being violently jerky.

>>17150848
You're mistaking me for someone else, that person said they never had a fast car so they don't know why it's happening there. I do have fast car and I do realize that I spin on launch a bit, not enough for it to be "useless". The spin WITHOUT a stiff rmm would make it nearly unusable, with it it makes it completely viable and eliminates any spin FROM THE WEIGHT TRANSFER. Obviously it still spins but no more than a rwd at this point. I still take my friends built 335xi from a dig easily.

>>17150876
>Obviously it still spins but no more than a rwd at this point.

Complete delusion.

>>17150811
That Civic runs slicks most of the time and is set up properly, so as to not light the tires up while rolling.

>>17150872
>what's the point of owning a fast car, you'll have wheelspin

>>17150872
you didnt read my earlyer post, if you have a correctly set up TIRE and SUSPENSION setup in conjunction with polyurethane motor and transmission mounts then you can eliminate wheel hop which would lead to torque steer and wheel spin

if you arnt dumping your clutch on a 6500rpm launch from a dead stop you can all but eliminate wheel spin

>>17150888
he doesn't own a fast car so that is literally his thought process lmao

>>17150876
Ah I see. Jesus I was confused there.

>>17150906
This is sad, it's time to stop.

>>17150888
More like
>what's the point of trying to make an FF car fast when you can just LS swap an old RWD Volvo

>>17150906
MS3's have a LSD. with a decent suspension and tyre setup, LC set at 3500, there's also such a thing as Boost By Gear. The turbo is roughly equal to a gt3076r. a proper tune would allow a pretty decent launch for FWD.

>>17150925
And an RWD car with the same power would still launch better. You're fighting against the laws of physics here and the laws of physics always win.

>>17150918
>why have something inferior when something superior exists
This can go for almost anything.
Bottomline is that a 400hp MS3 is still cool, regardless of whether it can be beat by an LS swapped Volvo or not.

>>17150932
Not saying you're wrong, but there is a way to work around FWD. It'll never be as good as RWD but it works.

>>17150939
It may be cool, but it's fucking useless. The only thing it's good for is doing highway pulls.

>>17150939
>why have something inferior when something superior exists
Usually because of cost, but in this case the volvo would be cheaper as well.
Right now it seems to be coming down to "I own a MS3 and I don't want to admit something else is better so I'll just upgrade this platform instead of switching to another one because fanboyism and confirmation bias"

>>17150958
>Usually because of cost, but in this case the volvo would be cheaper as well.
Not to mention having the actual greatest engine ever built. Cheap, dead reliable, monstrous aftermarket support, and 8 cylinders in a V like God intended.

>>17150958
You spin your stock shitbox Volvo out in 5mph turns, last thing you need is actual power.


Stick to the bus, bitch.

>get an old volvo shitbox and drop a shitty pushrod instead

Lol

>>17150958
So...according to your logic, everyone in the world should own a Volvo 240 with a LS.

>>17150953
I don't see why it couldn't be a fun car on a track.

>>17150991
Because it'll under-/torquesteer straight off.

>>17150989
No, when did I say that?
I just said that building the MS3 to make 400hp is a waste of time.
They are fine cars.

>>17150958
>stop liking what I don't like

>>17150989
Every enthusiast should own at least one LS-powered car in their lifetime.

>putting some merican piece of shit in a Volvo
>not running a redblock with mad boost
Y'all some boring cunts

>>17151014
is rather just throw my wallet to a bum and fuck my cousin and get it all out of the way

>>17151004
I was paraphrasing.
It may, or may not be waste of time. Honestly I think it's fun shitting on brand new "Muscle" cars on the highway.
Besides, what's wrong with roll racing?

>>17151034
>stressed to the brink of death or relaxed and effortless for the same amount of power
I'll take the V8 thanks tho
>>17151040
>Besides, what's wrong with roll racing?
Nothing, but when that's all you're good at it's kinda gay

>>17151034
Why stick with a measly four cylinders when you can have 8 and add boost later if you really want more power?

>>17151044
Less gay than being good at nothing.

>>17151014
Every enthusiast should own a M70 at least once in their life

>>17151064
yugo m70?

>>17150433
Not big turbo if it has an internal WG

learn to boost....

>>17151065
BMW M70. M73 is cool too

>>17151084
>less power
>unreliable af
>overly complicated
I'll stick with the LS lmao

>>17151064
Every enthusiast should spice it up and try a bit of everything. Before my ms3 I had a 944s2. Good little na 4 cyl, then 928, big German muscle, after the ms3 I'm planning on a sw20 to try out mid engine with some awd shit box as the dd. Got to drive plenty of ls powered cars my dad had a c3, c4 and c6.

>>17151089
I dunno, my 750 has 300hp while my old Firebird had only 150hp. It wasn't all that reliable either.
But hey, more V12 goodness for me

>>17151064
The m120 and the jag v12 are honestly better

>>17151044
>Stressed to brink of death
Obviously you know nothing about the L3K9.
As long as it's tuned properly and maintained properly you will get plenty of life out of it.

>Roll racing is gay
You must drive some sub 200hp shitbox.

>>17151141
I dunno. My old boss's brother had a M120 powered Benz, cursed it to no end.
My uncle has a few M120 powered mercs too and while doesn't call them bad outright, he does note that they are "difficult".
Would like to try one out but I don't really like the outer appearance of mercs from that era.

Can't comment on the jag. Jags look like sex though.

>>17151176
>Obviously you know nothing about the L3K9.
Why would I care about that motor?
Why do you think I was even talking about that motor?
I was replying to the dude saying volvo redblock.
Calm the fuck fuck, your insecurity is showing.

>>17151075
>IWG = Small turbo
Its designed to bolt onto the factory exhaust mani while still delivering similar performance as a off the shelf PTE5860.

NVM, I thought you were saying the MS3 would be on thing verge of blowing up with that turbo.

>>17150450
>Biggest small turbo
So it's a small turbo.

>>17151224
So, just like the M70 and M73.
Eeh, maybe I'll have a look at one. The looks are one thing but I can probably get over them with some light mods.

Perfectly happy dailying my M73 tho

>>17151256
If you think a Garret Gt3076 is small, then yes.

>>17151280
The m120 makes more power, the amg heads are very good, as far as I know all m70/m73 are sohc 2 valve

Any V12 is pretty nice amyway

>>17150925
as i said at the beginning of this thread the issue isnt going to be wheel hop/wheel spin off the line so much as turbo lag that would work against you while racing from a dig, i have to deal with this issue in the form of trying to pull out while turning left from stop signs in a crowded city enviornment its not unbearable but its definitly noticable compaired to somthing with less power but more usable power on the lower end

>>17150452
>small fast spooling turbo
are you stunned?

>>17151321
The M120 does make more power that one I'll give you.
Even if the M70 is the bottom of the barrel V12 out of the bunch, it's still miles better than any ls will ever be.
What's with ONE FUCKING LAP

Very bold statement here my dude

>>17151327
somthing like a disco potatoe type turbo with a smaller inducer and larger extruder would be advantagous in this type of application somthing that comes onto boost early and is well into the power before the end of the rev range

I wish more bmw fags tried to modify the N series v12, that one is DOHC 4 valve, it already makes 600 on the m760
It has variable lift, timing and direct injection, I bet you could get 800hp out of it with a proper tune and more boost, some people already get 700hp out of them

>>17151380
>>17151397
150hp was way too high, the piece of shit had only 145 according to wiki. Fuck that noise, no more American cars ever again.

>>17151414
It's quite pricey and has a shitty aftermarket. Would love to see one dropped in an E31 8 series.
