Most recently was a 2004 Acura TL 6MT. I think it is absolutely the best looking sedan in the past 20 years. Just wrong wheel drive. Had all the parts to build a turbo kit for it. My friend made 380whp on 8 psi from a gt35, and that was the plan. Got a full paint job and I did the wet sanding and buffing myself. Saw how cheap 335s became and decided to get one and sell off the turbo parts for the tl.
Prior to that was a 2005 G35 6MT sedan. My first and last Nissan. Nothing inherently wrong with it, I just realized I hate Nissans. Never again.
Before that, 2001 Corvette 6MT. Cam only and it made 425rwhp. Was fun but I got tired of big loud V8. The wife is still mad I sold it.
2002 Subaru WRX. I originally had a vf39 and exhaust, made 280whp. Spun a bearing so I did a JDM V7 swap, and a US 6MT. I liked it but the V7 didn't like the us 6mt gearing. I had a greddy rotated kit for it, but sold the car to buy the Vette before installing it.
2005 Acura TL 6MT, loved it, just hated car payments. Sold it and everything else was cash.
1996 Honda Accord H22 swap. Wasn't fast but was dead nuts reliable and looked good. Lowered on tein/agx, 17s, and nsx calipers.
1994 Camaro z28 6mt. Cam only and it made 360whp and went 12.5 @ 113.
1988 Honda Civic LX 4dr. $400 car and you won't find more fun going so slow.
Can't find pics of these:
1989 Honda crx si. $100 car and worth 100 times as much. Loved that car.
1989 Ford Mustang notch back. Loved how it looked, hated how slow it was, since it was an AOD 4 cylinder. 88hp. Eighty eight. Crank. It ran 18s at 64mph. Biggest pile.
