I think the R32 is a great car, but I'd be suprised if it had a torque advantage over a stock EVO at anything beyond 2500 rpm. It would be interesting if one of the shops with an AWD dyno could shed some light on this.

 

I haven't seen a dyno plot comparison yet. The R32 is too new.

 

This is a big problem here in the UK. Many people don’t want huge HP figures and even if they did cant afford the fuel to get them. So we have to try and max engines for torque. To do this I would say go for the stroker kit, preferable a 2.3 with a high compression ratio (this will limit the top end performance but give you an amazing low and mid range with very good off boost characteristics). You could make a stroker, take a 4G64 crank, a decent set of rods and some good pistons (pref. high comp.) and you will have a 2.3. Then I would go for a ball bearing conversion on your current turbo. This should make the thing spool up VERY early and be a bit more robust. Or you could go for a new turbo, but keep it small. Personal I would say the HKS 3037s as it is spot on for what you want with the stroker. If you didn’t want to go the stroker route then you could see 400+lbsft on the standard turbo, but that is running it very hard and at 2.3bar (I think) at the low end. I would only do this with the ball bearing conversion. The high lift cams are a good idea, I would say Tomei Procams. You may also consider water injection as this will enable you to run higher boost/more ignition. N2O is an option, but I would not recommend it on a daily drive. For more info have a look at http://www.lancerregister.com and good look mate!

 

Have you considered checking out the STi as well? just asking bc low end torque is phenomenol on that car and that's without sacrificing the driveability...i know cause i own one right now..,however i'm looking to sell my STi and get an EVo bc for my intended purposes it'll be a weekend project, track car and nothing beats the performance aspect of the Evo.

Upgrade your turbo actuator.. upgraded springs allows you to spool even faster and maybe increase boost past the stock maximum with a 3" dp..

 

Thnx for the suggestions. I am unfamiliar with how the turbo actuator works. I am a very technical person so I do understand most things but have not learned about this yet. Please explain.

Is the 3037 turbo the fastest spool up option availible for the stock 4G63? How soon does it spool on a stock 4g63? What about with a 2.3L stroker kit and high lift cams? Does anyone know?

As for the STI? I dont like the Boxer engine (due to maintanence and accessibility), not to mention detonation and piston slap. Also the price is a bit much, and I dont like the seats or suspension or active dirvetrain. If the evo had a 2.5 I-4 with less boost it would be perfect for me.

 

New Turbos.....$3,000+

Getting out of my range now!

 

Ya it would be out of my range too, unless I get an Evo RS. Then I can use the money saved. Hmmm, definatly something to consider.

 

There are a LOT of used Evos out there... Find one with a good 3" exhaust and low miles...

 

i heard 3'' downpipe will loose u alil torque not increase it... 2.65'' downpipe is what i'd get

 

I have a 3" exhaust and I haven't lost any torque - Guack should know - he rode in my car for a while...

 

Chris, I'm asuming you have an aftermarket intake. When does your turbo start to whistle? What rpm?
My car is basically stock and that happens around 2500 and the power kicks in at around 3000.

 

a smaller downpipe is not going to increase torque. reason being back pressure. this is not an NA engine. there is a turbo wheel inbetween the exhaust side of the cylinder and the rest of the exhaust. I woudl assume that backpressure would actually hurt spool because it puts more pressure on the turbo itself therefor making it work harder to make boost. These are just my opinions so please don't take any to heart, just how what I feel works on our cars.

About the same as you. Here's my engine bay:

 

I don't know, I just experimented with a Buschur 2.5" DP and my stock one. I already have a 3" HKS catback. With the stock DP and HKS catback, I did not lose any low end torque.

Now, when I changed out for the Buschur DP, i immediately felt loss of low end torque, like you had to put more revs in to get rolling and very weak in first when not spooled compared to stock. Once spooled, look out. Nice power increase over the catback. Much louder, too.

I put back the stock DP and immediately felt my low end come back, but midrange and top were not as nice as the Buschur 2.5".

Even though the stocker is slightly smaller and has crushed sections, the Buschur 2.5" is straight through. IMO, downpipes like HKS and this one are more than enough for power gains unless you are upgrading the turbo. I would not consider a 3" unless i was going 3" test pipe or 3" hi-flow cat.
