Scott Posted November 22, 2011 Share Posted November 22, 2011 I'm currently waiting on a cast elbow being delivered so that I can get the cold side of my turbo hooked up to the intercooler. I'm a little unsure of how to go about it though so I have a few questions if the guys who have done this sort of thing would be so kind Is there a recommended maximum angle to route the pipes with? I know that ideally it would just be straight but this really isn't going to happen. The tubby is a precision 67mm so I had to cut off the end of the compressor housing in order to fit a 90 degree cast elbow (Thinking about cutting it in half to get 45 rather than 90). Should I try to keep the bends under 90? On ebay I saw a u-bend pipe, should I be avoiding these? Looking at it it would probably create the easiest solution but probably not the best. What is the best way to route the pipes? Is it better to go up and into the wing where the stock piping goes? Personally I would rather avoid this as it looks a little messy for me but if it's the best route then I might consider it. Looks like it would take a LOT of pipe to go this way. I've also had a look at going past the steering rack/ARB, I think this seems to be the method of choice. If I decided to go down this route is it the norm to go over the ARB? Where do I go from there? Big U-Bend pipe or do I need to cut into the inner wing? Thanks for any pointers you have Quote Link to comment Share on other sites More sharing options...
dandan Posted November 22, 2011 Share Posted November 22, 2011 (edited) I did mine without a 90 on the compressor housing - dropped down past the alternator area and then a big gradual U bend out and back in to the intercooler.

Scott Posted November 22, 2011 Author Share Posted November 22, 2011 I did mine without a 90 on the compressor housing - dropped down past the alternator area and then a big gradual U bend out and back in to the intercooler. Did you not need to chop the compressor housing at all? Was it the H-Cover? I had literally no option unfortunately. When you came out past the alternator, what did you use to connect to the U-Bend, 90 degree bend? Was it a 180 bend you used from the intercooler or less? That's the way I was thinking of doing it.

dandan Posted November 22, 2011 Share Posted November 22, 2011 H cover Scott - no chopping at all. No doubt my cast manifold altered the alignment compared to your setup, I guess it made this bit easier. I editted to add a link but if you go back to the start of my project thread you'll see all the pipes being made as that was one of the first jobs I did. There may be some clearer pics there but I can't look as I am on a terrible internet connection. From memory the U bend actually works out to a bit less than 180degrees and it is made in two pieces with a straight join. Quote Link to comment Share on other sites More sharing options...
heckler Posted November 22, 2011 Share Posted November 22, 2011 On my cast manifold, the pipe goes straight down, couple of 45 degree bends/silicon hose, into a 90 degree bend to the I/C - and it clears the steering gear! Quote Link to comment Share on other sites More sharing options...
Scott Posted November 23, 2011 Author Share Posted November 23, 2011 Thanks guys, those suggestions and examples are pretty much what I have in mind. I'm hoping for 180 ubend from the intercooler, 90 degree from the ubend and then straight-ish onto the turbo outlet (which will have a 45 degree cast elbow aiming it at the front of the car). I'm thinking that I might need a 120 degree bend also just to lift over the steering gear but I'll have a better idea when everything is in place. Fingers crossed Quote Link to comment Share on other sites More sharing options...

I wouldn't have a hope of getting that in lol. Quote Link to comment Share on other sites More sharing options...

Marty Posted November 23, 2011 Share Posted November 23, 2011 Mine also went down on my supra too, wasn't too much effort to do to be honest, was a little tight as it passed the bottom rad pipe where it enters the thermostat bit. Quote Link to comment Share on other sites More sharing options...
mellonman Posted November 23, 2011 Share Posted November 23, 2011 i managed it with the old route of intercooler in the wing with some of the old orignal stock hard plastic piping for the stock intercooler. Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted November 24, 2011 Share Posted November 24, 2011 I sell a 2.5" 1 piece aluminium pipe that goes from the turbo to intercooler if that helps? Quote Link to comment Share on other sites More sharing options...

Paul Whiffin Posted November 24, 2011 Share Posted November 24, 2011 Looking for 3" Paul We run 2.5" ic pipes off the turbo on cars pushing 800bhp with no problems. I can have one made in 3" if needed though. Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 24, 2011 Share Posted November 24, 2011 (edited) I had mine point down with that manifold Scott so you must be able to do it, that was with a H cover. edit. http://i30.photobucket.com/albums/c338/jamie450x/install8.jpg Edited November 24, 2011 by JamieP (see edit history) Quote Link to comment Share on other sites More sharing options...
Scott Posted November 24, 2011 Author Share Posted November 24, 2011 I had mine point down with that manifold Scott so you must be able to do it, that was with a H cover. Lee said he cut the end off and welded on a 45 degree elbow? Said it was impossible to do it any other way with the boostlogic mani? I think he did the same with the other builds he has done recently also. Quote Link to comment Share on other sites More sharing options...

The outlet of my tubby is 3" and the inlet of the intercooler is 3" so I would rather just keep it the same all the way through. Would you not need my car to make one though? It isn't going to be the same as different turbo/manifold setups I would have thought? Quote Link to comment Share on other sites More sharing options...

Sorry to rudely interrupt here guys, but what's the going rate on these 1 piece 3" turbo-i/c pipes Paul??. I'd also be interested in one of these pipes, if you're planning to get some made up??. My current turbo-i/c pipework is a Pick 'n' Mix!! Quote Link to comment Share on other sites More sharing options...
