Trying to hit 250whp, help?

[yudkib]

and i think blkzoomzoom had some strange black magic with running 16 pounds and a block of dry ice strapped to his SMIC... something crazy like that.

people with 3" exhausts, turbolifes, and SSFTC's dyno at like 205whp on 10psi with a dyno tune. an exhaust mani and a better tune does not equate to 50whp. sorry, but no.

maybe my post sounded as if i was saying he had just fmic and exhaust, those were just the "quality" parts that stood out to me.

you wouldnt expect just a fmic exhaust,10psi and tune to = +100whp over stock

not when you leave out half the parts..

intake
hardpipe
fmic
intake manifold
cams
exhaust manifold
downpipe
3" exhaust
tuning
injectors
who has all these parts and isnt making 250whp? lets here from them

blkzoomzoom just sprayed co2 on his IC. he adjusted cam gears, retarded ignition timing, had a really good exhaust and tune going and 13psi with race gas. hand ported manifolds etc. pretty much all homemade stuff + mpi and race gas. it was sick but dead now. lasted more passes than any other car i have heard of here.

psi also doesnt relate to HP. on a good flowing setup when a turbo is flowing 10psi it is actually flowing more air then a poor flowing setup at 13psi. etc so tekkies setup at 10psi could be moving more air than blkzoomzooms at 13psi for example. think cfm not psi.

if you still dont believe it go for a ride in a sr20det 240sx with full bolt ons with a nonBB t25 and you will get an idea of T25 at full howl. 240sx guys usually get stuck at 220-230whp with full external bolt ons and tuning before adding cams.. this is with higher drivetrain losses than FWD cars. nothing left after 250 though, just more torque and high temps. then comes the T28 or bigger and the sickness continues lol

 

[yudkib]

well, the sr20 is hardly the fsde... i think thats clear to everyone. at least i hope.

 

[jeffmsp]

thats not what I am arguing.

i should clarify though: to get 250whp on the stock motor, a larger turbo doesnt just help, its necessary. you can probably squeeze about 225whp on the stock motor + stock turbo.

im arguing that you can do more than 225whp on the stock turbo. sure the engine may not be long for this world, but the turbo can push 250 before its out of breath. whether you wanna risk your FSDE is another question

what would be cool is to see numbers from someone with a built motor at 14-15psi on the stock turbo. I bet they are making great numbers.

 

[yudkib]

its possible that an intake and exhaust manifold with cams and a bitchin tune nets you the last 25whp. this is true. 250 is still awfully high for the stock block on the stock turbo - so ill agree with your assessment, its a matter of longevity.

I doubt anybody that has the cash to go forged would want to keep the stock turbo lol. People almost always go with a 28rs at minimum.

 

[yudkib]

bzzz wrong. HondaEat-R was forged on the stock turbo, for one. surely there are more.
and you have to remember - a lot of people go with a budget built shortblock if they blow a stock motor. they might not do head work or top-notch bearings, but theyll grab some forged internals for the rebuild just to know the motor can hold 250whp without any issue.

 

[SeR_Cyclops]

In his defense he bought the car that way. A old man owned the car before him and it was fully built and had a fully built tranny.

 

[yudkib]

HAHA i didnt know about the old man thing. i knew about his built tranny, his built second tranny, built third tranny...

[MSPDriver]

Wow this topic BLEW UP haha, thanks for all the advice, I've looked into more and I am 99% sure that I am going to go with the SSFTC, after doing some research and hearing from you guys it definitely seems like the best option.

 

[DarkAngel]

Dang I really want to finish my build......

This is actually the power goal for mine. After some serious thought, and my brother helping me out, we managed to get a GT2560 Turbo( great price ). Its a bit bigger than the GT2554 so I am happy about that. Later down the road I will upgrade to a GT28RS as I had planned on. I just want it to match our MazdaSpeed3. Looking at the Garrett site I should be pretty good on making my power goals with the turbo I got. I am still going to send in my current GT2554 to get rebuilt by a local shop so I have a back up at least.

GL on your goal. I am almost there, I have everything forged. Then the tuning begins.

 

[yudkib]

gt2560, in my opinion, is the perfect turbo for the stock block. the compressor side is a little small for a forged motor, but it should respond much better at high RPM.

 

[Ricktalife]

Any clue how much boost you can run *safely*?

 

[yudkib]

id have to look at the compressor map again. its a GT25 and disco potato hybrid.
if youre considering replacing your turbo, just go straight disco potato unless you can find a 2560 at a good price.
the 2560 would have been a better factory turbo for sure... but its too much a "half-step" between the OEM turbo and a disco potato.

>=O dont you be talkin s*** about my car!! shes going to get a disco potato one of these days and either a microtech or haltech to help with the timing if i decide to boost more then 8-10 psi

 

[yudkib]

ten psi? weaksauce. even aram pushed more than that - and he didnt push that motor at all.

 

[thecrash91]

im talking on the disco potato, from the info ive collected thats about the threshold where you should start thinking about messing with your timing otherwise i could join zoom zoom boom =[ and ive got some oil issues im trying to take care of, the car drank 2 quarts in 3k miles, hoping its not burning it and its just leaking out of the oil pan gasket, i saw the engine was a bit wet.
