Mark brooks Posted January 3, 2016 Share Posted January 3, 2016 I have a totally stock 1996 j spec, I'm on the process of getting bpu components Full exhaust system with double decat Air filter Fuel pump FCD Boost controller Can I push more boost if I ran hybrid turbos with the stock j spec fuelling or would they be near maxed out at bpu?

j_jza80 Posted January 3, 2016 Share Posted January 3, 2016 You'd really want 550cc injectors, so you'd need to run a piggyback at least to get the most from it. Link to comment Share on other sites More sharing options...

Scott Posted January 3, 2016 Share Posted January 3, 2016 BPU jspec will still hit 10AFRs so there's definitely headroom.... not sure how much though as you don't want them running at 100% if you can avoid it. It really depends on how you drive the car though. Link to comment Share on other sites More sharing options...
Mark brooks Posted January 3, 2016 Author Share Posted January 3, 2016 Yes I'm in Hockley, I'm planning on keeping it original so don't want to go to far. Thank you for your help Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 4, 2016 Share Posted January 4, 2016 In theory, with a fairly lean map, 550 BHP at the flywheel. You'd not be able to get near that with hybrid stock turbos. Link to comment Share on other sites More sharing options...
sideexitsupra Posted January 4, 2016 Share Posted January 4, 2016 I saw 421BHP on my BPU J-spec. Thought it was enough for road use, for a month or two... Link to comment Share on other sites More sharing options...
