x2 on that one. I did a 88 Si trans in my 91 at one point in time and used a 87 prelude clutch since it filled out on the pressure plate and flywheel fully. And that was recommended by Keth Gillespie, owner of Hasport, before Hasport was even in existence. Odd you are putting a HF trans on that tho......I am starting a build on a crx soon that will involve a D16Z6, T25 turbo, and an HF trans....going for mild turbo,frshly built engine, and some sort of decent gas mileage. Plus I thought it would be cool to boost on a HF trans since first gear goes to around 60 mph. Anyway, back to topic!
