Use ^^ that method Karl, you'l be fine..


f13 + 20xe

I'm puttin a f25& cossie flywheel with a S15 clutch on my 1.2 turbo,with nos

If you want one thats slightly quicker through the box them go for the f16 c/r (close ratio one)

Was going to say that, if its all about closer ratios then use the F16cr box lmfao, not all f13s are cr by the way. So its not like saying a F13 box is better acceleration as it clearly isnt.

mine is a cr box and box has been strip'd and rebuilt before it went in

my seh ran a f16cr box on 22 spline shafts and during its known lifespan to me it only ever had an outter cv i know its not got the same power as an xe but i gave it some serious crap. pod,autotesting,backroad thrashes and 5000 miles in 6 weeks!
