Mods for GP2

Have a GP2 with 34K miles, live in PRC (People's Republic of California) and it's my DD. No plans to track or AX it. All stock with exception of Forge IC and WMW Resonator delete pipe. Really like how the mods work when it's spun up but looking for next steps that don't ruin DD abilities and keep it legal in CA (i.e. no CELs).

Have read all the threads on this site but would like to hear from other CA GP2 owners that have upgraded theirs and what worked best. Real world CA experience not stuff that I can't run here or make it a bear to drive. All mods need to be removable too.

FWIW, my shocks haven't taken a dump yet.

It will all depend on your goals for the car. You've already done the intercooler which is one of the best mods to do first.

My GP is fairly mild as I have race car for full out mods.
I would really recommend the powerflex torque arm bushing inserts as they help get whatever power you have to the ground.
Craven Short shifter, really gives life back to it.
Hsport rear sway bar
Some rear Hsport control arms and proper alignment.
Then there are engine mods like Forge recirc valve, ECU Tune and so on.

The best bang for the buck is an ECU tune

but you have to remember that you may not pass emissions with it, and if your car is under warranty there is a coding error stored in the ECU so the dealer will see it.
So we always recommend the Forge Intercooler as the first mod as you'll see the power gain with the lower temps, but no effect on emissions or warranty.
CAI intakes are waste if you want power as they just don't work to lower temps. But the intercooler does lower temps after the turbo.

Drone if very subjective as each person's ear is different and also will be effected by which exh you have. I feel the GP droned on the Hwy with the stock exh. I switched to the Akrapovic to eliminate it.
A catless downpipe will always be louder than a catted downpipe. If you can find one of the old Akrapovic DP's that was the ideal one and what I have on my GP with no drone, but a good tone and power gains.

Following this post since i want to get some upgrades on my GP as well right now it's all stock. Nothing crazy since my R53 track car is heavily modded. i had a JB+ for a month but Took off since i kept getting lean codes then had to get the fuel rail sensor replaced, and that was it dialed at 40%.

I did a Manic tune. Forge intercooler. down pipe. Maybe about 30 hp increase.

+I like the power difference, but it's not a dramatic increase.
- I don't like the sound change from the downpipe when cruising on the interstate, it's louder overall and there's a drone quality to it. I've never been an
exhaust person (hey look at me)


Looking into upgrading the turbo to slightly larger one. I heard good things about
Owens turbos.

Hi there

Just wondering if there was any difficulty fitting the Alta Intake with the standard GP2 strut bar?

Thanks in advance
