A few q's about the EVO III and my setup

[Malero5]

Here are me current mods
3 inch downpipe and back exhaust
750 cc inj
walboro 255
Aeromotive AFPR
built engine with 1mm oversized valves/bsek/2g pistons/1g rods
264 HKS cams
3 inch MAF/MAFT
2.5 inch intercooler piping with skyline intercooler and an SSQV HKS BOV
DSM Link

Basically everyhting is done except for the Exhaust Manifold/turbo/o2 housing.

Right now I am going with the EVO III 16g. I am planning on purchasing it form turbochargers.com along with their GT manifold http://www.turbochargers.com/store/product_info.php?products_id=121. I was wondering if it was the real EVO III or the GT...since the turbo is only 459.99. The manifold is already ported and looks like it will be perfect for my needs. But here is where i am having problems.

Since I am looking to max out the EVO III would it be better to go external? Can the manifold do that? I am planning on porting the turbo eitherway to match the 7cm gasket.

Next is the o2 housing. I know the 2g can go to about 2.5 inch with porting...but owuld i see more added benefeit with the EVO III o2 housing ported to 3 inch (would match my exhaust and such.) I am not going to go with an external dump...it doesnt add power and it is soooo loud. I am already loud enough witht he 3 inch exhaust/venting to atmosphere.

I am looking to hit about 400 WHP on a good tune and race gas

TYIA I am really looking forward to this track season...and I am hoping to hit high elevens with some weight reduction and slicks altohugh i would be happy with twelves on a FWD.

They sell both the MHI and GT.

A side note. . . Why would you buy an evo3 and run the he!! out of it to make 400whp, when it would be easier to do this w/ a 50-trim and even on pump gas? This would be about $200 more; the money you'd save on pump gas vs. race gas if you drove the car regularly.

BTW, an evo3 is barely a high 11 second turbo for AWD. You'll have to lighten that car to no end to hit 11s.

well with slicks...and basic mods to the front suspension i should be fine. I have two 1990 plymouth lasers and when my tranny starts to go im gonna ship the other one to shep for a rebuild/lsd so i dont think it should be too hard to make the car run quicker then the average AWD. Most people that do that much modding go with a bigger turbo. I plan on making the car weight about 2500 pounds or so..maybe a little less. I already removed the AC...im taking out he backseat/tire/spare stuff. I am going to scrape all the sound stuff that reduces road noise and such. I am only going to run race gas at the track..when it is daily drive it is going to get 91 and run at 20 psi.

AH! you want great spool up for the street and a turbo you can yank on a little at the track . Remember, you'll be tempted to remove weight from the rear to counter the weight transfer at the track. But this will make her real squirrelly in the curves. Just a thought since you still plan on driving her on the streets.

Also running MAFt or SAFC w/ 750s is going to be a bear to tune becasue of the hellatios timing advance... But, it CAN be done. Also, larger injectors are notorious for having high dead times so adding that in the mix plus the high timing from large compensation will probably get you a little pissy by the end of the day.

I think the evo 16g is more than enough for a awd to hit 11s. If it doesnt there is a problem with the tune, the motor, or the driver, Or just not enough suporting mods.

 

[Malero5]

Well i want to put as much weight on the front tires as possible. i am planning on getting 2 adjustible shocks for the front so ic an lower it before track days. My intercooler is huge so i am afraid of damaging it on the streets. With dsmlink tuning is a breeze and I will have plenty of help when i turn it on the dyno after the turbo setup goes in. Between the camgear/dsmlink i will have plent of tuning. Either way i was have built the car around daily driving/occasional track days.

I don't know. This is probably just me here. But, Shape just dipped into the 11s w/ an evo3 16G. 11.8 sec. He had great 60 foots as far as I'm concerned... This was at 30 psi and race gas...He saw no gains from going to bigger cams than 264s... This is just my opinion, but that is not more than enough to hit 11s. That is just barely enough. A bigger turbo is better for the 11s. If you cant hit 12s w/ an evo3 16g, then yea you don't have all the supporting mods and/or you're a sub-par driver.

IMHO, to be more than enough, your car needs to sign up for weight watchers, you need stickies, and consequently a built tranny that can handle the shock.

you guys have been beating around the bush!! his origional questions were never answered!

I went 11.4 with a evo316g on race gas and 11.8 with pump gas.
I am sure with more tuning the car would go low 11`s on race gas with the evo316g.
I wish I had pushed it longer before switching to a gt35.
But A friend of mine has it now and will be running 9`s with it.

That's great! what was your weigh in? what was your trap speed?

 

[Tom N]

That's great! what was your weigh in? what was your trap speed?

just over 3100lbs and 119.55

 

[Maverick3169]

Wow, thats VERY good! What kind of boost levels were you running on the pump gas runs?

 

[siceclipse]

yeah! thats awsome!!

 

[Tom N]

Around 23-24 on pump.


A frind of mine just went 12.8 @ 107 in his car (full weight) on only 15psi of boost on a evo316g.
The evo316g really is a great turbo.

You don't have to tell me man, I use one as well!
I just didn't know that it was able to get into the mid-low 11's. I'm running 22-23 psi right now for daily driving, and she pulls great.

 

[Malero5]

I need some answers

 

[siceclipse]

HAHAHA!
sorry Malero, looks like we forgot abut you!
you have enuff suport here to let you know that the EvoIII is enuff to launch you into yhe low 12's high 11's. Just test and tune and you will make it!!!

You have nothing to fear from a PROVEN turbo!!!!

Regards

 

[Malero5]

will going external benefeit me much?

Going external can always be a benifit.
It gives you better boost control.
