intermediate shaft and boost question

[thisxdayxfwd2]

i need to know what size, pitch that approx length bolts that bolt my intermediate shaft in? Also i have a evo 3 16g with a fmic and a full 3" turbo back. there is no cat in it. ive been told the evo 3's like to boost creep. will i have a problem? should i put a cat in?

the size and pitch on the intermediate shaft bolts should be 10mm by 1.5 pitch. as for the length, 40mm is what's popping in my head but I could be wrong...it's been a while since I've had to replace any of those. as for the 16g, I had one on my 1g awd and never had a boost creep issue....but I could have just been lucky!

I had an Evo III 16g on my GST and was running a test pipe instead of cat and didnt have any problem with boost creep. Damn kink in the oil line ruined that fun for me. Broke and cant afford a rebuild for it so the DSM is down till i find a replacement.

As for the bolts.
Those use a 14mm head and I believe the threaded part is a 12mm with 1.25thread pitch. Not 100% sure but almost positive. From what ive been told 1g and 2g uses the same ones.
