t3/t4 turbo bolt size

[integra_drk]

Does anyone know what size the 5 bolts are from the turbo to the downpipe on a t3/t4? I have been looking for a while and have not been able to find out. TIA

12 or 13mm i think

Depends on the turbo. The T3 I have here off a Merkur has 13mm bolts on it. Probably a standard size actually, but a 13mm fits fine.

Do you need the head size, or the thread size?

thread is M8 x 1.5, as I recall.

I've always taken the turbo into A&A Trading Post | Ace and grabbed one of the guys. I got my wastegate, turbo, and downpipe bolts that way. Worked great, took about 1/2 hour for us to test sizes and lengths, but they had everything I needed. :)
