hello all, im going to running dsm boost on my dohc f22b in my 94 accord ex coupe and was hoping to run 9 psi. i was told that i should be able to hit 290 whp after tuning. my questions is are the 325cc prelude injectors big enough or should i run dsm 450s? i'm sending my ecu to john vega for a base map and idk what injector i should use. any feedback would be great thank you all in advance

 

Theres no reason to not just do the 450s.. There is room to play with and/or upgrade youre setup in the future.. No point in getting one set and then have to get another set for more flow later on..

i was thinking the 325cc cause i have the h22 head already... therefor no money spent.. but i can also just go the the junkyard and get some 450s for cheap too.. i just hope that the 290 mark was for real thats what the tuner i talked to said he hit with his stock ls with 9 psi.. they have pretty close to the same comp. ratio.. 8.8:1 i believe.

 

Go with the 450's no use in going to the tuner and possibly running out of fuel delivery capacity. It's better to run the 450 peak & hold injectors at lower duty cycles.

 

get the 450's.

also i think you should lower your hp goal a bit, ive seen built f22's just hitting the 300whp mark on built engines and bigger boost (15-18psi depending on turbo).

a stock f22b1 would be more around 220-230whp at 8-10psi like this one http://forums.evans-tuning.com/viewt...hp?f=32&t=1845

it will still be a fun car that makes lots of torque. get it tuned safely and dont worry about the whp# so much

 

this is a jdm dohc f22b. not a b1. the person i talked to that is a tuner at his own place beyond redline in green bay wi had an ls integra that he never took the vc off of and said he ran 9 psi and hit 290 when it had 154000, my motor has 54000. they have practicaly the same comp ratio. thats why i dont see why it would be a problem.

 

totally missed that you said dohc in the first post. in that case i assume you will be making some better power. post up the results when finished, im interested since you dont see too many dohc f22b's

 

Get the 450's. That is a good start. Eventually you are going to want to upgrade and then you will have some room to grow. Albeit very little room to grow, but there will be a little room to grow.

 

ok i guess ill just forget about the 325s lol. im gonna have to find some 450s make some power and kill some camaros lol
