5SFE header Options

[Cory]

I'm trying to find a header for my 5SFE (which we all know is rather difficult ) I have found headers for the 90-93 Celi GT 5SFE and am curious if anyone knows if the exhaust ports/bolts were changed between the 5th gen and 6th gen models? I've also looked at 91-94 MR2 headers, which from what I've read only require modification to the downpipe to fit the Celi. Anyone have experience/insight on this? I'm really trying hard to find a 4-2-1. Thanks!

i have a set of pacesetter 4-1 headers from a 5th gen celica on my car. The flange mounts up perfectly fine with the 6th gen block, the only problem you are going to encounter with them is the bottom mounting flange that attatches to the downpipe is a different size and the distance is about 1 1/4" between the original down pipe and flange. To solve this, the first time i went out to an exhaust shop, bougth a new flange and a metal gasket from my local muffler shop, then welded the flange up to the bottom of the heads after we cut the old flange off with a sawsall. Then we just bought some bolts, buttoned up the bottom flange loosely and then reamed the top flange onto the block. The problem with that setup was that my downpipe was hittin my oil pan and boiling my oil. So i added an oil cooler witch helped. But then i had some damage to my exhaust thanks to a nice sized rock that i ran over and ended up having to re-do my entire exhaust system, so when that happened, i had my downpipe re-made to give some clearance between the oil pan and the piping. So if you do wanna get headers off a 5th gen, be ready for some simple but tedious work.
