andy2986 Posted February 26, 2013 Share Posted February 26, 2013 hiya,Well im nearly at the end of my year long disco rebuild. Started as replacing the boot floor and finished up as a full on rebuild. New chassis all axles stripped and rebuilt etc, anyway I decided to pep up the engine a little and have on its way a full width allisport intercooler, Ive upped the boost a little on the turbo and done all the fuel mods. I will be re-routing the turbo actuator (?) Pipe to the plenum rather than the turbo itself so it sees the true pressure at the engine rather than at the turbo, I believe this will make up for any losses in the extra pipe work and the larger intercooler.My question is what to do with the second pipe that goes from the turbo to the FIP ? Should I take this to the plenum or leave it where it is?My reason for asking is there was talk (RR Blues i believe) of it increasing lag if the FIP pipe was referenced from the plenum as opposed to the turbo.What do you all think ???Andy Quote Link to comment Share on other sites More sharing options...
jad Posted February 26, 2013 Share Posted February 26, 2013 I have my waste gate plumbed to the plenum and boost gauge, and the fuel pump plumbed to the port just after the turbo. Works fine. Jad Quote Link to comment Share on other sites More sharing options...
andy2986 Posted February 27, 2013 Author Share Posted February 27, 2013 Cheers Jad, Thats what I will do then. Andy Quote Link to comment Share on other sites More sharing options...
jad Posted February 27, 2013 Share Posted February 27, 2013 Just to add. I bought my turbo second hand. I dont know if the previous person had touched the waste gate but my car boosts to 1.3 bar having it plumbed in like this. Im not sure if 0.3 bar is a realistic pressure drop across an intercooler. It might be best to move youre wastegate back to standard and adjust it while using a boost gauge to monitor it. Jad Quote Link to comment Share on other sites More sharing options...

disco_al Posted February 27, 2013 Share Posted February 27, 2013 can't remember exactly, but i did use a banjo bolt and a new turbo to fuel pump pipe from LR cut down and fed into the boost gauge pipe. i'll see if i can find the size (i think i got it off here somewhere) Quote Link to comment Share on other sites More sharing options...
jad Posted February 28, 2013 Share Posted February 28, 2013 Not necessarily... But better safe than sorry! I think it might be an M12x1.25 but will have to check what I bought. Jad Quote Link to comment Share on other sites More sharing options...
jad Posted February 28, 2013 Share Posted February 28, 2013 Yep m12 x 1.5 for the threaded hole in the middle of a 300 inlet manifold. I got a banjo bolt from bgc motorsport for about £7 jad Quote Link to comment Share on other sites More sharing options...
andy2986 Posted February 28, 2013 Author Share Posted February 28, 2013 Thanks for that really appreciate that. BGC look like quite a useful company. Andy Quote Link to comment Share on other sites More sharing options...
