Midnight-280Z Posted June 19, 2008 Share Posted June 19, 2008 Hello everyone, Well I ordered a crap load of parts so I can get my engine in and working....I was wondering, for the intercooler pipe size what should i do? Some say 2.5" and some say go 3" (because of the 90mm throttle body). I don't know what should I do...Please help. Here's what will be on my 75 280Z engine wise...keep in mind i will most likely upgrade in the future. 1998+ RB25DET NEO Nismo N1 Oil Pump Nismo N1 Water Pump Nismo Timing Belt Nismo FPR (will purchase real soon) Walbro 255lph fuel pump JGY Intake Manifold Q45 90mm throttle body Custom Intake w/Nismo Air Filter HKS BOV HKS Manual Boost Controller Custom 3" exhaust Once everything is in and done I'll be sure to post some before and after pics Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted June 19, 2008 Share Posted June 19, 2008 most people have an intercooler with 3" inlets and outlets.. and run 2.5" intercooler piping you can run 3" piping.. it won't hurt you. up to you Quote Link to comment Share on other sites More sharing options...
Midnight-280Z Posted June 19, 2008 Author Share Posted June 19, 2008 SWEET....now time to look into angles of the pipes so can order them..know any good place that have aluminum pipes that can be welded? polished if possible...it will match many things under the hood...I'm drooling just thinking of how my engine is going to look when it's done....everthing should look nice..topped with a Nismo strut bar. Pretty awesome to say "I got Nismo Parts on my 33 year old car" Thanks for the reply Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted June 19, 2008 Share Posted June 19, 2008 For my L28 turbo.. I ended up buying 2 180 degree U-bends... You can cut 90 degree elbows or 45's or straights and everything all right in front of you. I would buy those and some longer straights with silicone couplers and you should be good! Take a peak at some pictures of members running a RB25 and you can get a really good idea on what you need Quote Link to comment Share on other sites More sharing options...
