btw its only a 15hp gain and imo it aint worth it.....turbo your KA if you want low end torque that the VTC gives you.
the diff cover i think is only just a cover with plumbing in it to an external resevoir. a waste of time unless this will be a 24hour endurance car. i've had my white 240 on several road courses with plenty of power and never had a rear end problem. sure you can do it.....but why? i've found out that just because it sounds good on paper doesnt mean it will actually work on the car. (maybe this is why my cars are so lightly modified)
if you dont want that S13 sr anymore i'll take it off your hands if i ever blow this one up.
