2.4l turbo selection

[dSmgs-T]

hey guys, i am closing in on a magnus 2.4 bottom end with a SBR stage V head deal and just trying to figure out what sort of turbo would work out for that size motor. ill probably use my pte50trim for break in until i select another turbo... i would rather not go 35r'd, like to be a little different. i was thinking maybe an s258et but im not sure if its too small or maybe a HX40. thanks for the help!

 

[toofast82]

any of the above that you mentioned should be work fine. You'll probably want more power than the 50trim can give you with the stroker. Hx40 will have good spool and capable of alot of power and not too expensive. We all know what the gt35r can do. Ive seen some good dyno sheets from the borg warner turbos but they seem to be pretty pricey. Good luck on the buildup

Before suggesting a turbo we should hear your goals for the car.
Dyno target? Desired quarter mile ET? Spool up requirements? Purpose(s) the car will be used for?

 

[dSmgs-T]

my goals for the car would probably be mid 5 to LOW 600's.... low 11 second 1/4mile with my nooby self driving. and as of now even the car can be called a weekend warrior since i have a work truck to drive around in. spool up doesnt really matter to me THAT much unless its like anything past 5k

 

[delta448]

Depending on budget, availability and your desire to stay bolt on or not, I'd say either a FP Red, Holset HX-40 or a Borg Warner S362ET.
Personally, I'd probably get the Holset.

I was driving a 2.3l with a bolt on SBR GT30r bolt-on on a nice 25psi DSMlink tune. The car made 400 to the wheels with a high 11 sec timeslip at 25. Plus that turbo could push more boost than that.. And better yet getting a different turbine housing (T3/T4) you could see way better performance. The turbo was internally gated and had no problems with boost creep (unhooked wga arm). The car fully spooled by 3900 on stock 2g MAS (MAF) and stock 2g exhaust manifold and o2 sensor housing on a 2.3l with BC272 and upgraded head. Too bad the car overheated and seized on me on the ohio turnpike on Christmas eve.

im leaning more towards the hx40, but idk if i should stay with mitsu housing or go t3..i cant get a straight answer from anyone, ive heard that a t3 holset isnt has good as just a mitsu. and of course i would really like to go with a BW but they are pricy by the way, what are your opinions on a motor break in?!

 

[viperlp01]

Im going with a holset and the bep housing mounted on a fp race mani. It is a great trubo for the price and you can make tons of power with a nice spool time. That is what i recommend. I just picked my fp race mani up today. Im running the hx35 but you need the 40

 

[dSmgs-T]

im definitely leaning more towards the hx40, but again, t3 or mitsu housing? also, what clutch do you guys recommend i use? i have a ACT2600 with a sprung 6puck and act streetlite flywheel?! good enough, or go bigger?

 

[grantman10]

The car i mentioned above felt good with a 2900 puck clutch. It wasn't as heavy as i thought it was going to be. It was a stock flywheel IIRC.

i have a FULLY BUILT 2.4L 4GCS FOR SALE CHEAP

You will need a divided t-3 if you wanna go that route. I think the mitsu flange would be easiest. Turbo trader has the holset do it yourself kits that come with everything to bolt them up. Get a good manifold and you are set.

Do you mean between the bullseye power t3 .70 a/r housing and the .55 a/r bolton housing. There are hx40s out there that come stock with a twin scroll t3 turbine housing. The .70 a/r housing will give you more power per psi: better for pump gas. Spool with a 2.0L is 20+ psi by 4400-4500rpms. So with a stroker you'll be fine.

The bolton housing will be plenty for your goal, however. Your spool speed will be the fastest. 20+ psi by 4100rpms with a 2.0L motor.

i have heard that you are the holset "pro" so what do you think my best bet would be to go with? i also plan on running e85 with this setup also. i was thinking more with the .70 a/r twin scroll but i really dont know...

 

[slowgsr]

I would go with a bullseye power turbo (borg warner), Im currently running the s258 in a 0.70a/r. On my old tired stock 2L, i was seeing 22psi by 4300rpm in 3rd gear.

The S362ET would be a great turbo for your engine, just get it in the 0.70a/r with the T3 inlet. The discharge is vband, makes it easy to make your own downpipe

Extremepsi.com is selling the S362ET for less than 1150.00 right now. Seems very competitively priced compared to the GT series garretts.

Anyways, goodluck with your choice!

 

[dSmgs-T]

thanks for all your suggestions!

Check out some of the Borg. turbos. I would run a t4 hotside with the 2.4 lag is overated.

I know you don't seem to be interested in Garrett turbos, but just about all of the Forced Performance turbos have a bolt-on version of them as well as any other turbine housing you may want: T3, T4, divided, undivided, etc... With a 2.4, you could spool any of them very well. If it was me, I'd try and spend the extra on one of the HTA turbos.

The HTA3076R would give you INSANELY fast spool on a 2.4 while still being able to hit your HP goals. The HTA3582R would spool a bit slower, but could hit your 550-600 HP number very easily. Then there is the HTA3586R, which would spool just a couple hundred RPM slower than the HTA3582R, but has potential damn near 800 HP! And, all of the HTA turbos, including the larger 82 and 86, have great manners for strokers as proven by many of the Evo crowd.

Just my $0.02...

 

[toofast82]

i would probably go hx40 with the .70ar bep housing with t3inlet and mitsu outlet.

What? MUCH Slower spool. bolton divided, t3 t4 all of them.

And about the same performance for a comparable turbo of the same frame size. More money for the o2 housing and for the turbo itself. Not a good deal.

The only difference is that FP has sponsored the track "legends". Hense the big talk of how many dozen guys at XXX mph with FPYYYY turbo. I'm sure any one can make 650whp with a BOLTON hx40 that spools to 20+ psi by 4K. Since a great guy, but a typical guy who has no secrets with no 'race team' and no monitary profit has done it. Who cares about 800whp potential when the OP wants a 600whp turbo and the spool speed of a more affordable brand of the same reliability is about 1000rpms sooner.

If you don't care about spool speed, be pleasantly suprised and get an hx40 with the 60mm compressor wheel and the .70 a/r t3 bep turbine housing (as mentioned). The smaller .55 a/r housing is the unit that has done 650+ whp, while at the same time showing the same powerband as the gt3076r (fp3052/gt30r).

My PTE SC63 did what the OP wants with my 2.4L block. T3 with .63 turbine housing.

I have the BW362et on my 2.4. It shredded my TRE stage 2 trans during a 3rd gear pull, and it was only a year and a half old. I got mine over a FP turbo because it can be rebuilt and the FP turbos can't.

Man, what are you smokin'?WTF

 

[Savage Talon]

Haha, why don't you school me. Please tell me how stupid I am for thinking a FP 3065 cant be rebuilt. Or do you consider replacing a center section rebuilding?

 

[dsm-onster]

Maybe he's saying that Garrett BB center sections never break???
