Recently fitted an STi type-r version 6 gearbox (with P1 centre diff on),to my 2000 P1 due to mine letting go of 2nd gear ,and from what i heard peolple were saying the gear ratio's would be exactly the same as the P1 box apart from a shorter 5th ?,but it definatly feels shorter gear'd in a good way though it actually feels a lot quicker but there ,however when going from 4th to 5th flat out it just feels like it dies off like changing from 3rd to 5th,do all type r boxes feel like this ??????

 

The type r has much shorter ratios than the P1, have a look on the transmission charts. Iirc the Type r box is geared to around 150 mph at 8k revs.

Banny

 

Stop whining and just drive it Pete!! LOL

 

What diff ratio does a standard P1 use? The type r will be a 4.4 so whist the gear ratios may be the same the final drive may be shorter now.

And no, mine doesn't bog down going from 4th to 5th

 

ive got 1 fitted but its not a smooth change in all the gears, is yours like that.

 

P1 has 4.44 diffs too - ratios below for STIVi type r and P1. type r should have shorter ratios all around and certainly shouldn't have a massive gap between 4th and 5th.
