NEED BY TOMORROW: 2.5" SV in MN

146 Views 9 Replies 7 Participants Last post by  aerosmith145
I'm in trouble... my exhaust system is made for a 2.5" sv, of which I was unaware. I need to get the car back together, as it's my only car to get to work. I have a set of +40s I'd be willing to give away for a 2.5" SV + o2 sensor. (my o2 sensor is shot) Otherwise I have cash if I don't feel it's worth the injectors. But I need to get it as early as possible tomorrow, Friday the 13th.

If someone local can deliver this for me, I'd appreciate it a whole lot. 952-261-8149.


Also, I'd like to add while it's off a ported exhaust manifold (w/ EGT tap if possible) MP headbolts, better headgasket, and SS lines. I have available two perfect (look brand new) T2 exhaust manifolds for trade if anyone is interested. I will have a SS oil feed line early next week from TU if someone sells me a full SS line set and needs the feed line.

which turbo? I have a 2.5" mitsu with a good O2 i can ship.
It's for a Garrett--sorry, I should have specified.
Hey Dane,
Just got your message. That exhaust will bolt up to a 2.25" swing valve. I pulled the exhaust and turbo of the CSX at the same time, and I double checked the swingvalve size since the turbo is sold, it is in fact a 2.25".
I can send you one via next day air if you want it that soon.

I'm stumped then man. The boltholes don't line up--I'm pretty much positive on that. There's two flanges stuck together--if they would separate, the front one would work. Are they just rusted together? I assumed they were welded.

BTW guys, I was looking to find one locally so I didn't have to spend an arm and a leg on shipping. And I need it for Friday anyway--Saturday's too late. Thanks anyway.

They have to, because the bolt holes on a 2.25" and a 2.5" are the same.
I had to grind the holes out a little on the exhaust flange but I put a 2.5 downpipe on a 2.25 swing valve.

The bolt holes are spaced 4.125 on a 2.25" flange, and around 4.75 on a 2.5" flange. There is a large-flange 2.25", but it's pretty rare.
