Setup Question

Post by **Silent Drifter** » Sun Jul 27, 2003 5:55 am

Im not a turbo expert by far an ive been tryin to read up but Im just wonderin if this setup will work. I wanna run 10psi so will 550 injectors an z32maf be fine or is that too much? also will this require me to get the JWT ecu? Thanks

For 10 psi the stock maf and 370cc injectors are OK. That is right at their limits on my car. I can push it to 11psi, but I feel better leaving it a t 10psi.

50lb/hr or 550cc/min injectors are probably what you want then. If you aren't going above 350hp then the JWT cobra maf with 50lb/hr will be a good fit.

what about stock maf with 444cc injectors an a safc 2? My goal is to hit high 12's, id be happy with a 12.99

You'd better not be the reason the Ebay auction for 444cc Nismo injectors ended early! If you are...I'll be pissed

Everything I know about the stock KA MAF says it runs out at about the same power level as 370cc/min injectors. 440cc/min injectors will saturate the MAF then you go lean, and then POOF! There have been some people who have hacked the S14 MAF with OK results, do a search for hacked MAF to see what they have done. I'd dig around in local wrecking yards to find a Cobra MAF as cheaply as possible for peace of mind. On a side note JWT says they only program for stock MAF, Cobra MAF, or Z32 MAF. As for injectors they said 370cc/min at 3 or 4 bar, 50lb/hr at 3 or 4 bar, or 72lb/hr at 3 bar. The 50 and 72 injectors are top feed (stock is side feed for KA24DE) so you will need a new fuel rail and pressure regulator.
