i have a gsr with ctr pistons..... i was told that my compression will be around 12 to 12.3

i hear that i should upgrade my injectors but im not sure what size injectors i should get.....

if you have any ideas please let me know.....


also i was told i need to upgrade my ecu to a hondata.... do you know witch one i should get....

just get some 440cc and tune them down with vafc or hondata.just get hondata it should work fine ,..

 

IMO I think 440s are too much. I use 370s on my motor, GSR with 13:1 CR and Skunk2 3s, runs good, not even tuned yet and still runs fine on 40psi fuel pressure.

With a set up like that, depending on what year your motor is, if your OBD1 I would try to see if you could come up on some Prelude injectors, those are about 270cc, if not just go on ebay or something and find some RC 310s, you should be good with those, plenty of fuel.

 

440's would be good if you had ITB's, but ive heard stock injectors ould be fine for a n/a high cr motor, of course thats what i heard

 

yes 440's are too much untuned ,but with a vafc or enginemangemet you can tune them down to wear you need them .if using stock ecu itd say stick in some 310s and adjust fuel pressure up. And a intank fuel pump wouldnt hurt either my .02 cents . good luck

no its not. What do you know go work on your STI and stop giving bad info to us honda guys


ask any raceshop or people with AM knowledge 440cc is overkill 310cc is sufficient for way more hp than you will ever have with 12.3 compression or your setup

 

why wont it work ? i dont understand why not?

 

440's will work; if you have Hondata or other programmable engine management. Overkill is a relative term. I am running 440's in my ITR and I could easily get away with 310's, but I have Hondata, so I can run pretty much any damn injectors that I want to. If I decide to bore my ITR to 87mm and run a 95mm stroker crank, I probably won't need new injectors.

Running obd0 345cc H22 injectors in my 12.2:1 LSVTEC, work great. I tune with VAFC.

 

i have a obd1 chiped ecu... i was told that should be find for now.. but i really should move up to a hondata..... do you guys think i can make it with the stock injectors?

 

call RC engineering 310-320-2277.
they will know what size injector to run..... my guess is 270cc

ctr pistons in GSR your compression is more like 12.89

hondata S200

 

i dont think its 12.8.. that really really high.... its more like 12.0 to 12.3
