I am using T25 off an SR20 for my D15 with a Y7 head. I want to run 7 psi maybe 10 on occasion.

My question is will my H22 injectors I have 290cc be enough?

I have no fuel pump or pressure regualator upgrades. I am going to ordered a tunned ECU once I get it all together. 450cc injectors seems like too much for such a small engine and low boost. I don't want to be smoking or have rough idle since this will be dailey driven. On the other hand leaning out and frying your pistons sucks to. Sorry for the newb question.

290cc no good even 450cc are only good up to 10psi. use DSM ingectors they are 450cc from mitsubishi eclipse for cheep.

And you have to tune it other vise big BOOM. good luck

Thanks. I am glad I checked. As far as the smoking, idle, gas mileage, what can I expect w/ a turbo D15?

Everithing is gonna be smooth if you use your stock OBD1 ECU chip it and at least street tune it. But remember no catalic converter you dont need back presure, too much back presure couze detonatin. And if you can, use external wastegate its gonna keep your boost more study.

With right tuner your car shuld idle perfect and gas milige yah its gonna eat a little maybe insted of 35mpg your gonna get 28-30mpg it depends how you drive. more boost more gas you know.

450 injectors junk the 290 and nothing is pretunes...

there are to many veriables to each motor and set up. get it tuned after ward

No such thing as to much back pressure, it just limits hp, spool and power.

Theres other factors in detionation your not edumacated on yet
