looking for turbo to get me to 400 whp with 2.4l

[bsbllfit7]

hey everyone im trying to get some thoughts from you guys on what turbo to run with my new 2.4l setup. I do have some requirements for the turbo. I want to run as low as boost as possible to get to this level. Also i want to have a streetable spool. Now i have been searching and have came across the fp green as a good turbo to fit this mold. Also the hx35 but i would be running quite a bit of boost to get to that level. The reason i want to keep the boost as low as possible is to extend the life of the turbo. When i say low boost i mean 20-25psi. Nothing crazy like 30+ psi. Lets hear what you guys have to say. I want to stay with the mitsu flange so a fp race manifold is in the mix shortly hear.

those guys werent just using a 16g, they were also running a medley of e85, race gas, meth injection, nitrous, stuff like that to get those numbers. I am not going to be using e85 or anything like this its going to be pump. At least at first. Also just because i have a 2.4l doesnt mean that its gonna make more power, i do get more torque however as well as much increased spool This is going to be a street engine, low rpms low spool and a reliable turbo for upper 300 low 400 whp. 20g seems ideal for the money and for my want of not running e85. A guy with a 2.0 just ran his 20g and at 20psi was making 396 whp i believe. That was with a 264/272 cam combo. I have fp2 cams in my very near future and probably 22 psi on pump. That should net me my goals but only time will tell!

No meth or nitrous. Any car with a good head will make big power. Big turbo doesnt mean big power... Good head means big power.

And no it was not with a 264/272 cam... It was with hks 264s.

Im not trying to be an ass or anything but i just see so many cars put together wrong and people spend money where its not needed. Stock block with a CB head is all you need .

 

[bsbllfit7]

still I WILL NOT BE USING E85. Because of that im limited to around 350 or so with a not so favorable powerband. I am willing to sell my evo 3 for say 250 (hell of a deal) and spend another 250-350 for a turbo that will give me a better powerband ( more what im looking for) greater max airflow and piece of mind. Dont get me wrong i love the evo 3's but on this engine IT WILL RUN OUT OF BREATH.

the problem with running any 16g with my 2,4l engine is gonna be that the turbo will run out of steam in the higher rpm, that is not such an issue for the 20g, sure if you want a peak horsepower number go ahead and have a higher number lower in the power band, but i am looking for a more evenly distributed power band where the 20g will allow me to have that power in upper rpms.

In "my experience with my stroker", youre not going to see a super long RPM stretch over stock. A e316g will get you to your power goals but you wont feel the hard kick as you would from say an hx-35/40 or any other larger frame turbo. In my opinion, pick up a Holset. You can find them super cheap and you wont be disappointed.

Hope all goes well,
Sean

 

[bsbllfit7]

holset is in the future upgrades as well, just dont want to deal with custom drain and feed lines right now

 

[Hubbell91Tsi]

He wasnt running e85 either, i will not say what fuel he was running. I honestly dont see it running out of breath, you wont know until you try... 27psi on a 14b, stock sidemount no knock, spiking 33 lb/min. e85 is where its at .

Agreed, if you dont run a fp 16g get a 35.

I believe that says 264/272 as well......someone correct me if im wrong

you arent able to run a evo3 at that kind of power on pump, it wasnt pump gas is all im trying to say, and i WILL BE STICKING WITH pump.

I was talking about curts car.

 

[bsbllfit7]

the guy that i keep bringing up that made that power on his car is giving a good name to the 20g, 20g's seem to be old news to us tuners but there is still a good ability in those turbos. I think that i could get close to the 400whp goal with that turbo on 92 pump, and for the money i think it would be the easiest route to that. Granted i might not keep it forever and upgrade to a holset or green. It would meet the goals i am trying to get to right now.

o ok sorry, thought you were saying that the thread i was talking about was on hks 272's. Thats my bad man.

the thread i am talking about is this....

Having run a 50 trim on my old 2.3L stroker and an FP Green on my (current) 2.4L motor before settling on a GT6235R, I realized one thing that hasn't been mentioned in this thread yet... It isn't so much as the turbo will 'run out of steam up top', as much as it will run out of flow up top, meaning that the standard Mitsu exhaust housings are just too restrictive to be able to allow the 2.4L to breathe on the exhaust side like it should.

I understand your goals, as they were similar to mine but realistically, these 2.4Ls needs a larger AR housing then what is offered in most Mitsu bolt-on style turbine housings. The largest bolt-on housing I was able to find was PTE's Mitsu-flanged bolt-on at .63 AR vs that of the Mitsu bolt-on housing's .48 AR. The .63 AR is the smallest housing I would even consider using with a 2.4L... I also had one other concern with my build: I didn't want to run an externally gated turbo (read: because of the CA smog nazis & snooping cops that think everything turbo has an aftermarket BOV on it ). If this is not a concern of yours, feel free to explore even larger AR housing-equipped turbos… Your 2.4L will thank you for it

 

[Hubbell91Tsi]

Dont go green man, i havent seen any crazy numbers come through yet. You can max it out on pump at like 418awhp. Only make like 433 on e85 . This was on an evo though.

 

[bsbllfit7]

what about the super 20g turbos that use the 10cm hotside instead of a 7cm or 8cm that should help flow. Also i am not concerned about emissions any longer, i used to have the car registered in portland where i had to worry but now we moved the registration to eugene so i dont have to worry about that. GO Ducks by the way! Im sure ill re-upgrade the turbo in the future, what ill get idk. Would you say that the 20g with 10cm hotside would be a better candidate then my evo3??? I feel it would, and it would give me the better flow as well.

 

[Kaotic_red]

I just cant see the value/price comparison with a 20g. But to each their own...

The larger the hotside, the better IMO

evo 3 16...

-1 to get 400 out of this you will be close to maxing it out. Better off running a larger turbo in a more efficient range. Like a Green or something like that.

GO BEAVERS!!!Roast the DUCKS!

dude, who are you hangin out with I have seen 480 on corn.

If my correction numbers are right the FP green in dsm trim is like a 51lb compressor (730 cfm), so it should be operating in a happy place in the compressor map on pump.

Thats odd, i dont remember saying that it was the best running most powerful evo with an fp green on it...

To the OP:
There are more than few options that will reach your goal.. I'll speak only for myself, for what I had...
HX-40, period...
I did 443WHP on 2.0L @22-23 PSI and 496WHP @29-30 PSI/not a full run let off @6K/... Look at my set-up for details.. With 2.4L and HX-40 at 22-23 PSI you'll be theoretiically at over 450WHP...
However my runs were on T3 0.70 AR BEP housing, but with the DSM bolt-on housing and 2.4L you won't be far off..
I had a big cams/280/ and turbo isn't so efficient at that level, but still makes power and it's solid... It is going to be for a nice combo for DD and reliability... In your case, cause@ 22-23 PSI, turbo isn't working hard... BEP it isn't going to be a restriction for your goals... For the price and performance you can't beat it... GL.

 

[bsbllfit7]

so your thinking hx40 with bolt on housing would be a better setup, i know it would cost about the same, just a little fabbing of feed and return lines. What are theoretical pump limitations on the hx40, i had also thought about the hx35, easier to find i feel and they can run 52lbs
