Was wondering I need to do some injectors and would like to use the Lude ones they seem to be good for cheap are they good enough for my set-up???

GSR block Pr3 pistons, ITR head ported, ported intake mani, getting when I do this I'm getting Skunk2 stage 2 cams, DC JDM header, I think 155 intank pump and STR fuel rail. Running about 12.1 compression
The head and intake mani is opened alot so do you think these injectors will be good enough? It's in a CRX non OBD so I can use low resistance injectors.

TIA Rob

 

First of all...where does the extra compression come from? Your setup should only yeild about a 11:1 CR. The only way you'll see a 12:1 CR with your setup is with CTR piston or pistons of similar dome volume. The other thing you need to ask your self is what kind of tuning are you looking to have done and what are your goals as for power. I say using lude injectors is a good place to START!!! You might find a need for increasing the size slighty, maybe 310s or 370s... if your looking to get higher number down the line, you should think about that now.

To answer your question striaght up...You can start with them, but don't expect to squeeze alot of flow out of them.

 

yeah prelude h22a injectors are ok...

1992-96 Prelude VTEC Peak and hold 345cc

 

With out a shaved head it's 11.4 then I shaved head .33 thou don't ask........... I hit 195 with CTR cams so I'm hopping for 210 HOPE is the key word....... I'm limited to the FVC for now so that's what I will be tunning with...... the pump I'm getting is 190 intank.

Thanks Rob

 

I'm running prelude injector's in my R I'm puttin down 205whp+ w/ 12.5:1 n s2stg2 cams....u'll be fine...Prelude injectors are 310cc...ur straight

96-96 Prelude injectors are 310cc....I have them in my setup...And like i said before i'm down 205whp+ with higher compression and a 255 walbro fuel pump.

you have more than 12.0/1 c.r. from what i know, shaving your head .33" should give you pretty much 1 FULL point of compression. i think that you are in the 12.3x/1 c.r. just to let you know.

 

I'm running OBD1 Prelude injectors on my LSVTEC.. I like them.

 

Running OBD-1 H22 injectors on my N/A LS!

That's what I thought...... I pulled the motor out and the head is off everything looks mint...... I'm claying the motor for my new cams Skunk2 stg 2 and degree everything then I will no how much I can move the cams on the dyno so I don't have clearance issues.
Thanks for all your help guys. Rob
