RB-GTE Posted July 29, 2012 Share Posted July 29, 2012 (edited) This is how my car currently sits: ARC intercooler with greddy bov on piping HKS intake 3" exhaust HKS boost controller I just purchased: Walbro 400lph fuel pump midpipe and top decat pipe (both 3" to elimate the whole cat) AEM wideband AEM turbo gauge HKS fuel cut defender Also will go with a higher grade spark plugs and some new oil... I just wanted to do everything at once. Anything else recommend to get for my BPU setup? I do plan on running it up to around 1.2bar and in TTC so want to make sure everything will be running healthy.

ripped_fear Posted July 29, 2012 Share Posted July 29, 2012 Restrictor ring. Link to comment Share on other sites More sharing options...
RB-GTE Posted July 29, 2012 Author Share Posted July 29, 2012 Restrictor ring. Oh yes, I already got a machine shop to make me one of those based off an exhaust gasket with the 2" hole through the middle. - - - Updated - - - Restrictor ring.

Guest Budz86 Posted July 29, 2012 Share Posted July 29, 2012 Fuel cut defender otherwise when you hit around 1 bar the ECU will cut the fuel to prevent the turbo's over boosting Link to comment Share on other sites More sharing options...
Guest Budz86 Posted July 29, 2012 Share Posted July 29, 2012 Ignore me, just re read that and you've got an HKS one! Doh! Link to comment Share on other sites More sharing options...
BOB B Posted July 29, 2012 Share Posted July 29, 2012 You would be better with UK 550 injectors fitted, Link to comment Share on other sites More sharing options...
st3ven1 Posted July 29, 2012 Share Posted July 29, 2012 You would be better with UK 550 injectors fitted, Then you would also need the 550 resistor packs and a fuel controller. Otherwise you risk over fueling the car. Not really worth it for bpu if you ask me. Link to comment Share on other sites More sharing options...
tooquicktostop Posted July 29, 2012 Share Posted July 29, 2012 1.2 bar with 440 injectors is pushing it, you will be going a bit lean at this level Link to comment Share on other sites More sharing options...
BOB B Posted July 29, 2012 Share Posted July 29, 2012 Yes, maybe not if he only wants 1 bar, I just heard talk of fuelling probs at 1.2 or upwards, Link to comment Share on other sites More sharing options...
listy Posted July 29, 2012 Share Posted July 29, 2012 Better to be safe and go for a 1 Bar RR and a boost controller set to 1.1 Bar. Eliminates chances of boost creep that way Link to comment Share on other sites More sharing options...
RB-GTE Posted July 29, 2012 Author Share Posted July 29, 2012 I do plan to go single in the near future so I'm not going to touch the injectors while I'm at BPU. And the power difference between 1.1 (16psi) and 1.2 bar (17.4psi) is quite minimal ? I may just stick around 1.1 to be on the safer end. Link to comment Share on other sites More sharing options...
HadeS Posted July 29, 2012 Share Posted July 29, 2012 You will see from your AFR if you are safe or not. I can't see upgraded cams, any head work or bigger turbos so 1.2 bar should be no problem for 440cc injectors. Link to comment Share on other sites More sharing options...
tony tt Posted July 29, 2012 Share Posted July 29, 2012 Stock intercooler would be more efficient for bpu as well. Once single i'd fit the front mount. Link to comment Share on other sites More sharing options...
