3sge header to 5sfe, how much of an improvement and will it bolt up? Options

[goferris]

hey all. i've been thinking about getting a header for my pretty much stock 5sfe and have seen the headers on ebay but realised that the 3sge came stock with what looks like a pretty decent header.

i was just wondering if it would better to get a stock 3sge header with the heat shield already attached vs buying a cheap header off ebay then wrapping it. would the performance boost (however little it may be) be about the same?

also i'm pretty sure it would bolt to the engine just fine but how about to the rest of my exhaust system and would it fit in the space there? i'm sure i would eventually just get a whole new exhaust system header back but in the meantime will this fit before hand?

another reason i ask is because i was chatting with lewfx the other day about getting a header and he said it really heat up the engine bay when he had one on his celi. since the 3sge header is a stock one with the heatshield i figured it would be a little bit cooler and a lot better quality than the ebay headers.
TIA

I'll dig up pics for that install on the MR2 - the bottom had to be cut and a new peice made because the bpipe would have had to have a funky jog down to clear the oil pan with room to spare but the basic Header part bolted up just fine. far as I know the car is still runnin like that with nitrous.
I'll find the pics as soon as my other comp is back up.
Hell - look at it this way - if the 2nd gen 3S-GTE manifold bolts up to both the 5s and the 3rd gen 3S-GE - why wouldn't 3rd gen 3S-GE not bolt up to 5s?

Edit: Found this: http://www.6gc.net/forums/index.php?showto...1&hl=header and it would seem he says the entire manifold is stretched [from what I can gather] but that makes zero sense if the HG's still work and the 3rd gen is a drop in upgrade to the 2nd gen how would they fit? Wouldn't the motor be longer in that case if ever so slightly? At any rate I know we bolted some 3S-GE header to a 5S head and it wasn't 1st gen cause that header is no better than 5s really [especially the Camry version which we also bolted up]. Seeing as the header probably came from MR2oc would it be more likely a 2nd gen 3S header? Anybody have pics of one of those? It appeared to be the same one as OP posted but that's pics over a comp so...
What might also be telling is has anyone tried to Turbo their 3rd Gen 3S-GE with 2nd Gen 3s-GTE manifold/Turbo/DP? UK guys?
Hopefully my other comp will be back from the shop tommorrow and I have the file saved with an indicative name so I can post up the progress pics I have. This is exactly why I always take pics of these kinds of things.
