with a gforce, youll most likely have to do some work to the tunnel area where the shifter comes through the floor. like i said, i have no idea what spline the oem input shaft is. im running a custom made pressure plate and clutch discs to match my input shaft from gfoce. but yes you will need to make sure the splines match up and that the correct pilot bearing is used in the flywheel, and that the input shaft is long enough due to the thickness of the adapter plate. adapter plate will be a custom made piece. i know a lot of guys are putting powerglides/th400/th350 behind the s2k engine now so there are a few shops making adapter plates, we made mine. the problem with finding a used gfoce for a high revving 4 cyl is the gear ratios.
to be honest, the gforce trans isnt needed for most applications. the syncrho ppg gear set godmachine mentioned will be more than enough for a lot of setups on here and cheaper. ppg also has a straight cut gear set that can handle a bit more power for a bit more money.
if i had a oem chassis s2k, id be running the ppg gear set in a heartbeat.

Yeah, some friends suggested a powerglide, but I want to be able to track/autocross as well as drag the car, so powerglide doesn't really meet that criteria.
Yeah, I'd go for the PPG gears if they were more common and I could find them cheaper used. The only reason I was thinking gforce is because they are fairly common and used in other cars and therefore I can likely find a used one for cheaper. What do you think would be good gear ratios for the S2000 (assuming ~500whp, and for the motorsports I mentioned above)?

yes for a high hp street car, slap in the ppg gears.
in my fwd civic, i had 1800 in a billet bellhousing and 4200 in a dog box gear set from liberty...still broke gears. part of the fun of making hp.

just remember with straight cut gears there is nothing stopping you from making a 1-2-1 shift or a 2-3-2 shift unless you have an aftermarket shifter (which gforce makes) that pushes the shifter towards the next gate (towards neutral). hope that sounds clear enough.

Definitely straight cut. If the money is going to be spent, might as well get the better/stronger gear style IMO.

I don't think so. Stantaur told me Lavins charged him ~$7k for everything for his g-force trans... that includes "entire bellhousing, disc, trans, shifter, driveshaft". Just the gears for PPG are $8k.
