stylieee Posted March 18, 2007 Share Posted March 18, 2007 Got a WON nitrous kit (single inj fogger) sitting in my garage that i had on a previous car, and im thinking about fitting it to the supra at about the same time i go bpu (+fmic). i dont have a progressive controller so i'll take it no higher than 50/75bhp for the time being. question is though, will the standard UK spec fueling system cope with bpu AND a small wet shot of nitrous? or am i going to have to upgrade the pump or anything?

b.weeks Posted March 26, 2007 Share Posted March 26, 2007 Don't know the answer - but interested to find out if you fitted this or not ... looking for inspiration on my BPU ... Quote Link to comment Share on other sites More sharing options...

Bob Posted March 26, 2007 Share Posted March 26, 2007 The UK spec pump should cope with it just fine (aren't they supposedly better than the Walbro pumps?). Ignore all the people who tell you nitrous kills your engine; it doesn't. A badly set-up system will kill an already damaged engine, but as long as the setup is done properly and the engine is checked out OK before-hand (compression test & definitely a leak-down test done 1st) then you'll not have any problems. I wouldn't take it above a 50 shot without a progressive controller, though. Quote Link to comment Share on other sites More sharing options...
Robbie Posted March 26, 2007 Share Posted March 26, 2007 on a side note: Nitrous kit = invalidated insurance policy. Its worth checking. Quote Link to comment Share on other sites More sharing options...

Ian C Posted March 26, 2007 Share Posted March 26, 2007 Pre intercooler? Quote Link to comment Share on other sites More sharing options...
JustGav Posted March 26, 2007 Share Posted March 26, 2007 Pre intercooler? I was just about to say that as well... Nitrous is meant to be injected as a liquid and as close the combustion chamber as possible to preserve its liquid state.. By injecting pre-intercooler, you are almost assured that it will enter the combustion chamber in a gaseous state and therefore not as dense.

Bob Posted March 26, 2007 Share Posted March 26, 2007 Bob, It depends on what revs you want to use it from. Never below 2500 anyway. Fair enough, I always used the 50 limit as a rule of thumb on smaller engine cars, but forgot that the Supra lump is teensy bit stronger than most!

Lucifer Posted March 26, 2007 Share Posted March 26, 2007 Pre intercooler? With no controller for larger horse power. 50 ish then go to plenum just before throttle body. Quote Link to comment Share on other sites More sharing options...
JustGav Posted March 26, 2007 Share Posted March 26, 2007 With no controller for larger horse power. 50 ish then go to plenum just before throttle body. Hold on a second, the plenum is after the throttle body isn't, heading towards the air intake runners.. Quote Link to comment Share on other sites More sharing options...
Bob Posted March 26, 2007 Share Posted March 26, 2007 On another note, I personally wouldn't risk going above 75 without going for a direct-port system. Quote Link to comment Share on other sites More sharing options...
