Black R

Ok, my buddy has a last gen civic si with the basic JRSC kit...
His numbers are 200whp/140wtq.

Now to date he has had the usual problems with detonation in the upper rpm band, etc.....

And for some reason he though his stock si injectors are 210 - although I would swear most honda's are 240, right?

Anyway, he was set on getting some bigger injectors in preparation for the 8lb pulley upgrade he wants to do next..... He thought some Venom 270's would be a nice upgrade. I advised him that at a minimum to go with 290cc 97+ prelude injectors, and since he is still going to use the stock ecu for a while (I suggested hondata in the future) - 310-320 rc injectors or maybe accel?

Somebody give me some suggestions on what to tell him... I know it's way OT, but a lot of the good tuners hang out here too...

Now he's asking me if the itr and b16 fuel rails are the same.....

venoms are pricey, but no doubt good. they've been recommended to me.

what is he planning to do to tune the thing? going to much bigger injectors will kill his idle and off boost driveability unless he can bring his static and idle fuel pressure down. if he decides to go oem, i have a set of 290cc 5th gen prelude injectors lying around. should be a direct plug in for his si, assuming it's a recent one.
