Will a 3.0 V6 downpipe bolt to a stock Garrett turbo?

[Tim_K]

I recently got an '89 Turbo SPirit, and it has a stock Garrett turbo on it, which I presume has the stock 2-1/2" downpipe. The cat and rear section of the pipe (with the crimps in it right behind the cat) look stock, so it may be a 2-1/2" downpipe. I haven't gotten under there yet to look closer, but I think the Garrett has the stock 2-1/4" swingvalve on it.

I have a complete exhaust system that was on my '93 3.0 V6 Shadow ES, and it's in great shape. It has the 2-1/2" downpipe on it.

My question is about the spacing of the bolts on the flange where it'll bolt to the turbo. Would they be the same distance apart on both the turbo and downpipe, so they can bolt together? It looks like the angles and length of the pipe are the same.

It'd be great and easy if this exhaust just bolts in. Because it was made for a Shadow and I'm putting it in a Spirit, I may have to lengthen the pipe behind the cat a bit, but that's not a big deal.

nope

an 89 turbo spirit *should* be a TI which means it *should* have the mitsu turbo with a 2.5" swingate

and it *should* have a 2.5" DP

They should be the same. Give it a try.

Yes, this car had its Mitsu turbo replaced with a Garrett. The exhaust system looks stock, so it should be a 2-1/2" pipe now.

I'll have to get under there and measure it.

The 3.0 DP IS different from a turbo DP...trust me, been there, done that.

[Tim_K]

How are they different? Angle of bend? Length of pipe above bend? Something else?

The turbo pipes have a lsight angle to them right at the top where they meet the turbo. IIRC the 3.0 pipe is almost dead straight. The turbo pipe is not. We tried using a 3.0 pipe on a turbo eninge...it was a no-go...
