george.bryant Posted March 10, 2005 Share Posted March 10, 2005 At the moment I have two facotry intercoolers that i got off a new zealand auction website (http://www.trademe.co.nz). What one would you guys recommend putting onto my L20et? It has no intercooler at the moment so Ill need to do some plumbing too (what do I use? Mandrel Bent Pipes?) also how do i set it up. Does anyone have pics or diagrams of intercooler setups on L series motors? Thanks, George Quote Link to comment Share on other sites More sharing options...

Cody 82 ZXT Posted March 11, 2005 Share Posted March 11, 2005 Take a look in the gallery and you should find some pics of the setups that are out there. If you click on the link in my signature you can see what I've done. Edit: look on this page http://www.angelfire.com/space/nismo1turbo/indexengineinstall.html Quote Link to comment Share on other sites More sharing options...
Ben Posted March 14, 2005 Share Posted March 14, 2005 Ideally, put 'em both in parallel. Less pressure drop & better cooling. But if you can only use 1, then I'd expect the RB20DET unit to be slightly larger, but not by much. Quote Link to comment Share on other sites More sharing options...
george.bryant Posted March 14, 2005 Author Share Posted March 14, 2005 put them in parellel eh...wont that create turbo lag to the baddest? Quote Link to comment Share on other sites More sharing options...
Ben Posted March 15, 2005 Share Posted March 15, 2005 Not at all. I 'd guess that it would take about 3 or 4 of them to equal the displacement of a 600x300x76 FMIC! Turbo lag is much more a function of turbo wheel sizes & exhaust flow than intake ducting displacement. What you're after is an efficient surface area with minimal pressure drop. Of course the smaller package you can use to achieve this the better. For an L20AET, I'd expect that a 400x300 bar & plate cooler would be more than enough to keep the charge cool. Upgrading your turbo to a BB core unit similar in size to the RB20DET would assist in this area too. You may not pick up much power, but you'll get better response & your temperatures will be lower. Which means that your boost could be safely raised further (tuning permitting). Quote Link to comment Share on other sites More sharing options...
george.bryant Posted March 15, 2005 Author Share Posted March 15, 2005 well i sold the sr20det intercooler today for twice as much as i paid for it so I could afford to get piping done on the rb20det intercooler. i wasnt really after a power gain just a better take off response which apparently this upgrade will help with. plus i have a bov on the way which should help things out a little bit too Quote Link to comment Share on other sites More sharing options...
