phil280zxt Posted February 22, 2006 Share Posted February 22, 2006 I'm in the process of planning out my spring intercooler install on my 81 280zxt and I need help finding a source for silicone reducer / transistion elbows. I would like to transistion from 2.75 intercooler inlets/outlet to 2.25 for the piping. Any ideas where I could find these?? I'm not sure if I will need 45's or 90's. The car is zipped up in its winter sleeping bag for another month. I've searched on this and other forums and also used google searches extensively. Thanks, any help would be appreciated.

mobythevan Posted February 22, 2006 Share Posted February 22, 2006 I bought all my stuff from http://www.atpturbo.com There stuff has the fiber reinforcement and the price was good last time I bought from them. A lot of the cheaper stuff has no reinforcement so watch out when your hunting around. Quote Link to comment Share on other sites More sharing options...
blake culp Posted February 22, 2006 Share Posted February 22, 2006 i got a kit off ebay, im sure it was the cheaper stuff that is not fiber reinforced, but it still worked out very well for me. I got the 2.5in kit for around 100$ and then just cut the pipes and used the supplied connectors. I think the key is to cut the pipes to that they fit very close, my pipes all but up to each other. If you leave a lot of space between the pipes the connectors can balloon out. My intercooler has 3" inlet and outlet so i boiled my 2.5" connectors and they stretched enough to fit perfectly. Back to your original question, im sure just about any 2.5" connector would; 1 stretch around your 2.75" intercooler and, 2 compress around your 2.25" main pipe.

nienberg.11 Posted February 22, 2006 Share Posted February 22, 2006 I like Blake's idea of boiling silicon couplers to get additional diameter out of them, at least in a pinch. However, I have to disagree with him on being able to compress a coupler that is .25" oversized and have it seal properly. I tried fitting a 2.25" coupler onto my 2" compressor outlet, and it didn't work out. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted February 22, 2006 Share Posted February 22, 2006 You can also try http://turbohoses.com/ Hoover is a Z guy from way back and has taken good care of us turbo guys in the past. Also, while you are on the site, you can check out a a couple of pics of his 240z in the projects/customer's cars page. Quote Link to comment Share on other sites More sharing options...
Supra510 Posted February 22, 2006 Share Posted February 22, 2006 http://www.hightempsilicone.com I'm not sure they carry 2.75 inch hose, that's kind of an odd size. Prices and service are good from my experience. Quote Link to comment Share on other sites More sharing options...

Clifton Posted February 22, 2006 Share Posted February 22, 2006 I got all mine on Ebay. Someone did have 2.75" hose on there at one time. That's what I used from the intercooler to TB. Quote Link to comment Share on other sites More sharing options...
Nigel Posted February 22, 2006 Share Posted February 22, 2006 The couplers that come with those ebay intercooler kits are rubber not silicone. Which is why you can heat them up and expand them (which may lead to a lot of boost leaks down the road). Real silicone is rated at 300+ degrees, and one elbow will cost you at least $30 (typically $40+) compared with less than $10 for rubber. I'm going to end up spending more on silicone couplers than I did on my intercooler! Nigel '73 240ZT Quote Link to comment Share on other sites More sharing options...
240hoke Posted February 22, 2006 Share Posted February 22, 2006 I second ATP they have a good selection, good prices, and i always get all my stuff quite quickly. The only time they have been out of stock on a connector was for a 2.5" straight piece -- they upgraded me to a hump connector for free instead of backordering, but called to be sure it was okay. I recommend buying t-bolts to -- definitly worth the investment. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted February 22, 2006 Share Posted February 22, 2006 I checked ATP and they do have 2.25 to 2.75 straight transitions, not sure about angle. They are $17.95 Quote Link to comment Share on other sites More sharing options...
phil280zxt Posted February 22, 2006 Author Share Posted February 22, 2006 Thanks for the info on silicone sourcing options. My plans are to transition from the 2.75 in/outlets on the intercooler to 2.25 piping with elbows. With my luck I probably won't be able to pull that off and will have to come up with a different plan. I hope that I don't have to resort to modificating the intercooler endtanks. It sure would make it easier if my Z was not under wraps at the moment!! Here is the intercooler I purchased on Ebay for $150. It's a Spearco 20x8x3.5 core.

violacleff Posted February 22, 2006 Share Posted February 22, 2006 Reducer elbows are very hard to come by. Hoover's boys will rig you up a ghetto fabulous one, in which they slice a piece of 1.25 off a straight piece, shove it into the elbow and charge you an extra 20 bucks for the "reducer" piece.. It may be cheaper to just buy the elbow and slice the piece off one of the straight pieces you already have and do the same thing. I second the silicone vs. rubber comment. Turbohoses, ATP, and Road Race sell very good material that will endure high boost. Quote Link to comment Share on other sites More sharing options...

cygnusx1 Posted March 1, 2006 Share Posted March 1, 2006 I posted this site a long while back but here it is again. They have some real unique stuff here that may or may not apply. I used some of their stuff for my CIA. http://store.airflo.com http://store.airflo.com/rubber-hoses---clamps.html The rubber parts are very heavy walled and tough.
