June Update
I've gone through most of the entire car and refreshed/maintained it to a respectable state. I made a few mistakes with the incorrect mods and had to replace them a second time, but luckily everything is easy on these cars.
What's been done recently:- I added +40 horsepower upgrading from stock to maxing out the T25 turbo with a K&N, 3" exhaust, electronic boost controller and wideband. Instead of spiking 10.5psi and holding 9psi to redline, the car makes 15-16psi and tapers to 10psi. Dyno results are exactly what you'd expect with these mods (pic below)
- I replaced the HKS Hi-power catback with an HKS Sport and absolutely love the subtle muffler and quiet volume.
- Fully complete: Engine Maintenance - new fluids, filters, belts, spark plugs, bulbs, engine/trans mounts, stereo, front brakes, LSD, clutch, o2 sensors
What's next:- Engine mounts - I tried OE rubber but they are just too soft and pathetic. I picked up a set of JGS rubber mounts from e1_griego and will give those a try.
- Seats - Ordering a recaro seat and bracket. Need a good Left seat, maybe s15 or whatever pops up locally
- Wheels/Tires - I have some 17x8 and 17x9 wheels and Hankook RS4 tires, just waiting on coilovers so they don't rub the suspension
- Suspension - The KYB shocks and lowering springs aren't terribly impressive and I know some of the suspension bushings need to be upgraded. I ordered the main adjustable arms and a few energy suspension bushings.
- Intercooler - I ordered an ETS intercooler core and am looking forward to getting rid of the sidemount piping. The aero bumper should look pretty good with a FMIC!
Please message me if you have a Bride MO seat rail for the right seat of an s13.
