I have a high compression, all motor LS (81.25 bore). Compression is around 12.6:1.
Car will be tuned with an SAFC/FPR until I can afford Hondata.

I'm currently in the market for some new injectors. Right now I'm running stock 240cc's cleaned/balanced by RC.

I'm planning on upgrading to RC 310's. Will this be TOO much fuel for my setup? The fuel pump is stock.

Any advice?

Thanks,
Adam

 

Nope.. I'm using Prelude OBD1 345cc Injectors in my LSVTEC with the stock fuel pump. I tune AFR with a VAFC.

 

Thanks.. any other input?

I am using OBD-1 345cc Prelude injector too on my N/A LS setup! Works for me, but are pushing higher compression than I am!

How much HP are you producing? I think H22 injectors would be fine for you!

 

stock 240's are good to 210 whp, if you are going to be over that, you might want to look into 345cc obd1 h22 injectors. More affordable than RC and more than enough potential.

Also, I would run fuel pressure at 55psi static and trim from there...promotes best atomization...i would not gamble with the stock pump considering Walbro pumps can be had for so cheap nowadays.

 

Thanks a lot guys. I've heard lots of debate on what WHP 240's are good till..

Any mods required for the prelude injectors? I know, I should search...

 

well, put it this way. JUN offers an injector upgrade only for their stage 4 engine packages, which are 220 whp...and the upgrade is to a 270+ cc injector (i am thinking it's really 280cc, but whatever-)

the obd1 'lude injectors should just drop in if you are running obd1 plugs and have a resistor box, since they are p&h.
