Jcrow Posted July 21, 2004 Report Share Posted July 21, 2004 Does anyone have a picture of a turbo grand prix downpipe? Is it braided? Is it steel pipe? Is there a gasket between the turbo and it? I assume it goes over the top of the transmission? Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted July 21, 2004 Report Share Posted July 21, 2004 i'll post a pic of mine in a few minutes.... but it's actually a solid pipe with a SS braided cover tach welded over the center part of the pipe...no flex joints at all like the crossover pipe has. it "sorta" goes over the top of the transmission where it bolts to the turbo...then kinda goes back around the rear head to the middle part of the firewall like where the NA 3.1 downpipe is. there is a bracket that bolts to the block (i think it bolts to the block anyway) and then a flange that meets up with the 'secondary downpipe' (for lack of a better term). there is no gasket used between the downpipe and the turbocharger. there is a donut type gasket where it meets the 'secondary downpipe'. the first few inches of the downpipe is actually cast iron, and then it goes into steel pipe with the SS braided cover. i'll get a pic posted in a minute....mine still has a foot or so of the secondary downpipe bolted to it.

Guest TurboSedan Posted July 21, 2004 Report Share Posted July 21, 2004 this is actually a downpipe i sold a couple months ago; i can't find any pics of the TGP downpipe in my garage right now (with the secondary downpipe bolted to it). btw, i think the entire downpipe is actually cast iron.

mfewtrail Posted July 21, 2004 Report Share Posted July 21, 2004 Just a random/related question, but how many miles were on that downpipe Joshua? Just wondering because mine on the TGP looks brand new w/ 70K on it. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted July 22, 2004 Report Share Posted July 22, 2004 you'd have to ask eclipse5302 (Jason)...that's who i bought the downpipe in the pictures from (i later sold it to The Burning Rom i think). the one i have in my garage right now looks much much better.

Jcrow Posted July 22, 2004 Author Report Share Posted July 22, 2004 Wow thanks. I don't know if that image will work if not try this http://www.intense-racing.com/GTP/Turbo%20-%20John%20Costello.html Do you really need flex in the x-over pipe? I have a grand national turbo and a huge volvo intercooler, and i'm waiting for my larger fuel injectors to arrive. So I'm getting excited about how I'm going to plumb all this together.

TGPilot Posted July 22, 2004 Report Share Posted July 22, 2004 Do you really need flex in the x-over pipe? ABSOLUTELY!! Jeff M has some phots somewhere showing what happens when a solid x-over is used...not a good thing at all!! 8) Quote Link to comment Share on other sites More sharing options...
skalor Posted July 22, 2004 Report Share Posted July 22, 2004 The reason the INTENSE turbo car doesn't have flex-joints in the x-over is because the 3800 SII has cast iron heads. We have aluminum heads that expand/contract more than cast iron will, hence the need for flex-joints in the x-over. Quote Link to comment Share on other sites More sharing options...

What year/model did the Volvo intercooler come out of? Quote Link to comment Share on other sites More sharing options...
Jcrow Posted July 22, 2004 Author Report Share Posted July 22, 2004 I dont know, I got on Ebay for about $75 its about as big as the radiator. I took out the A/C condensor so hopefully it will fit there. Quote Link to comment Share on other sites More sharing options...

I took out the A/C condensor so hopefully it will fit there. If it's the 740 intercooler like I think it is, then it *might* fit there...the radiator endtanks might be in the way though, I'll measure my volvo IC(spare from one of my volvos) and then the radiator and eye it a bit since I've been meaning to anyways...it definitely won't be in my TGP though. Not giving up my ac on this one , I might on my next TGP though..and I'll probably go w/ an izuzu NPR intercooler or the like since I think I can snag one of those for a decent price.
