Estimate my performance threshold? EVO III swap

[SubversionX]

Hooray for first thread posted on DSMTuners!
I recently got a 97 Eclipse GS-T with 150k miles on it, so I had the engine of an Evo III (50k miles) ripped and swapped. I changed the belts, got it realigned and tuned, and was wondering if anyone here has done this before, or knows what my threshold for power was?

I'm currently running 1 bar on the upgraded Big 16G Turbo, and FMIC. It's all stock internals. HKS turbo timer AFC Neo Fuel Piggy Back (needs retuning) but I haven't gotten a lot of time to fool around with them. GReddy Evo exhuast and
Pacesetter Tubular manifold are the only other performance mods done.
I'm trying to baby this car until I know exactly how much I can push it without ruining my engine. I'm hoping to get around 400 bhp, but I understand that may be just out of reach for a stock engine.

Also, I've got about a $1,000 to spend on this car for the next few weeks, and was wondering how to spend it wisely. I was thinking of getting a standalone ECU; does this seem like a good idea? or would it seem reasonable that to get past 400bhp, i might want to put that money toward a good 4g63 block, and build it from the ground up?

I don't know... what do you all think?

Or, my mom's boyfriend has an 09 'vette. Should I just swap his supercharged LS7 and hope he doesn't notice? HAHAHA he's a jerk....

i would say, save your money. get it tuned as it is, run it while you save, build the **** out of it and beat the vette

 

[jjgrizz73]

He has a new sc z06? G/l beating that with a fwd dsm and a few bolt ons

I might just do a tune and some cosmetic work to it, then. I'll be going on deployment in a few months, and should be coming back with about $10k to throw at the eclipse, and $10k to throw down for an MKIV Supra. Then I'll tear up his stupid vette...

 

[herewego]

get it tuned and sell it before you deploy. the MKIV it MORE than capable of takin the vette's lunch money, but you better be bringin more than $10k. however, if you don't need the status of the MKIV... get a MKIII. you can pick one up for 2-3k that has a blown head gasket, build it, and buy enough stuff to make 5-600 rwhp and be done at 10-12k. however, i believe you could also do it with an AWD DSM. just depends on how much you can pick one up for.
good luck man

 

[jjgrizz73]

Highly doubtful, if it is what he says anyways. A stock Z06 on stock tires ran a 10.9 1/4 mile and a procharger can add the Ls7 up to nearly 700whp stock blocked and run much better times than a dynoqueen supra. Id take a AWD dsm over a supra anyday.

Back on topic, if you're going that route why bother asking what you should do in the first place??

 

[SubversionX]

I've enjoyed the Eclipse, and would like to see it more as a hobby dd, but put the Supra into the garage and make it one of those masterpiece works of art. $10k is just my planned down-payment. I'll be pretty well-off after this deployment; wooooorld cruise baby! Hazardous duty pay, and tax-free zones hittin up everything from Dubai to Bahrain to Japan to Australia!

The MKIV has just been one of those dream-cars in the back of my head for a long time, and getting my hands on that 2jz is in the base of my heart .

I don't see myself selling the Eclipse anytime soon; it's been a fun little zippidy car and I'd like to keep it around for a little while. Maybe I'll let my wife drive it... MAYBE... (that means no.)

I'm not serious about taking on that corvette... yet... haha. It was just something I thought about after getting to drive it for a few minutes before coming to work...

But really; does anyone have any estimates as to what the evo III engine can hold?

 

[jjgrizz73]

Evo III motor isnt much different than the regular 7bolt. It has the same power limits and really depends on the tune. I generally say around the 500hp level, more has been done with great tuning and also less has been done with poor tuning. A standalone isnt really needed, DSMLink is fine

 

[boostsickness]

I agree, some guys have gone upwards of 400-500hp on stock internals, but how long it will last is another question. If you plan on turning up the boost, i'd get some fuel to support that 16g. Another option with tunning is a chip from dsmchips.com if you dont know how to tune with link.

If he got a complete swap he should have the E3 injectors (560cc?).

1bar(14.7psi) with 450cc injectors is right about the limit. Maybe squeeze a little more(16-18psi) with a wally 190.

 

[SubversionX]

Wow really? That much on stock internals? Right-o. I'm looking into dsmlink and it looks promising. They even have download for Linux platforms, awwww how sweet It's nice to know that they keep us stereotypical asians in mind...

I'm running the 560 injectors. Probably gonna use a chunk of money to upgrade fuel pump, rail, and lines.


...OR I COULD GET A HUGE ALUMINUM SPOILER!!!

NOO!! fight the temptation!

With a walbro 190 + 560cc injectors you can run around 18-20psi without your injector duty cycles blasting through the roof.
If you plan on running higher boost then that you should pop in some ARP headstuds. People have ran higher boost on stock headstuds but why risk it?

If you want to go with the walbro 255, you'll need a adjustable fuel pressure regulator, otherwise you're stock FPR will get over-run and hence run rich. The rail really isn't a weak point.
I'd do this for fuel upgrades:

• Walbro 255
• Adjustable FPR
• SS line from Filter to rail

Before you really crank up the boost look into either getting dsmlink or at least a datalogger.

You will have to get the spoiler for sure. And get some sweet flamin graphics for the side of ## dsm to. Everyone knows they add like 300hp at the wheel

HAHA and some spinners!

 

[rlacasse1]

Not just any ol' spinners. They got to be spinner hub-caps. PIMPIN

 

[SubversionX]

haha alright! Maybe I'll get some of those fender-vent stickers and some street-glow?!

So, just a recap on what was said;
Walbro 255
Adjustable FPR
SS line from Filter to rail
APR headstuds
dsmlink
datalogger

if I get the Walbro 255, is there any reason I might want to upgrade my injectors as well?
what would I want to do next? ignition? would COP ignition be reasonable?

 

[BigSorn]

stock ignition is fine for your goals.
are you going to keep the 16g? or go bigger?
if you get link, I would say get bigger injectors, so you never have to get new ones.

 

[SubversionX]

Alright, i may just get some new plugs and wires if I don't need to work out the ignition.
Umm, I'm not sure about a bigger turbo right now. Maybe if I can find one for a reasonable price once I've balanced out the rest of the things. What size injectors would you suggest?

 

[jjgrizz73]

for injectors i usually say go as big as you can tune for. If you go dsmlink go 1000+ if you stay with a piggyback like a safc then 680cc max. I ran a evo3 16g with a 255 and 580cc injectors daily at 24-25psi. Very awesome street turbo but without E85 and a great tune I wouldnt look to break much more than 350whp. Theres many routes you can go, just do alittle research theres tons of info on here.

 

[SubversionX]

Awesome; I think I have a clear idea of what I'm going to do
Thanks a lot you guys, this has been the best forum site I've ever used haha

 

[xhackerekx]

why people recomended dsmlink ??? ecu flash good idea and save money.

 

[SubversionX]

What's the difference between them?

 

[xhackerekx]

big difference e-z for setup. read this u find anserwer for everything.
