Don't have an ECU, but I'm out here.

Can someone verify for me that 4gperformance is still around?? I have tried to find a contact number and cannot. Their website domain is for sale as well. The thing is I would just "swing by" but I live in Alabama so that would be quite a drive for me to possibly find out they don't exist...

OP, if you haven't already you should sign up to Mitsubishi Galant VR-4 Forum - E39A 4G63. You will not find better GVR4 specific information anywhere on the internet.

I'm here for the summer months, otherwise I'm at school. I've got 2 Galant VR4s, one with lots of go fast parts and one that is clean. This summer those 2 cars will turn into a go fast, clean Galant VR4, and a roller for sale.

Why are you switching out the awesome 1g BOV for anything else? There is no need to do that. At most, you should be looking at installing a Dejon Tool Leak stop mod for your current BOV and it'll be perfect for just about anything you throw at it.

Terrible idea. Buy a car with a 4g63t if you want performance.

I've been running HKS 264/264 cams on my 16g and wouldn't trade for a 272/272 setup. 264/272 may be the perfect compromise, but the mid range torque that I have with my setup is just ridiculous.

The 14b is a very capable turbo. ~270whp is obtainable for the regular Joe granted a healthy turbo and motor. I would be looking at a decent FMIC, larger injectors, fuel pump, AFPR, keydiver chip, wideband, SAFC, and 3inch exhaust, and an MBC.Let the Keydiver chip do most of your work for...

For those who are recommending keeping the 560 evo 8 injectors...I would recommend against it. I saw ~95% duty cycle on pump gas on my bolt on Evo3 16g setup, running 93 octane making 326whp on the dyno with my Evo 8 injectors. I would recommend a larger fuel pump (Supra TT if possible, I...

I've ordered from them. Their service was excellent. The part shipped quickly and arrived exactly as described.

Just run a Keydiver chip. It does all of these corrections and more for you. You'll have perfect tune and will only have to use the SAFC for minute adjustments of +/- 1%

http://www.dsmchips.com/ This is what you should add to your setup for a great tune.

Turbo can have several mm of shaft play side to side, but generally in and out means the turbo is junk.

I do not see any sense in doing that. If you want a performance motor project, just buy a turbo AWD DSM and go from there.

I ran a 12.8X @ 108 on the authentic Evo III 16g at 20psi with no tuning but a Keydiver chip. I didn't post it up because this was a while ago and I have since lost the time slip. Since then I've fixed and added a few things, added HKS 264/264 cams, and a little more boost. As soon as I hit...
