1What injectors? Empty What injectors? on 8th April 2015, 7:06 pm

Ok guys so I need some help here please, what size injectors will I need to safely run at 350 hp, My plans are to fully rebuild my stock engine with forged pistons, and make sure that it is healthy. I already have a 3 inch turbo elbow, Pace front mount intercooler, and Mongoose exhaust with decat. I also have but not yet fitted some HKS 264 cams, so I'm hoping this will make for an engine with a decent amount of hp, but also more midrange torque than it has at the minute, also which turbo is best?, I don't really want to run crazy amounts of boost as I would prefer everything to be running at say 70-75% of it's operating range so that there is a bit of a safety margin if that makes sense?.

560cc injectors should suffice some people may say otherwise but I'd be very confident in saying they will be up to the job for 350bhp Smile hope this helps man !!! Also if I rememeber correctly if you go too big on the injectors you need to up the fuel pressure reg but could be wrong on that if you need anymore help from me just pm.

Cheers guys, that's great, I was thinking that around 560 cc should be ok for it, I have spied a set of new Nismo 555 cc injectors as well, so I'll see what they are at nearer the time when the auction ends, as always this forum is helpful and friendly cheers
