T70 turbo? And you're only going to use 370cc injectors? That's a little on the stupid/risky side isn't it?

370s are usually used with T25/T28s...

if the tune is good and that t70 doesn't creep it should last.

it holds 8 lbs nicely.. i think i might change the injectors to 550cc... would i have to Tune the car again ?

yeah.. your injectors are just limiting your power levels. you fine now at that power. 550s will be good for maybe 400.

TUNE TUNE TUNE

Sell the t70 and get a t28

don't skimp out on that. If you don't plan to spend good money on a good tune, don't even bother attempting this.

if you change injectors you will need a tune. Why? because the computer will tell the injector to open at 50% when 50% open on a 370 is a lot different than 50% on a 550. i'm no engine expert though. and also, i don't see why 370cc should be bad with a t70? Won't the 370cc injector only LIMIT the amount of power it will put down?. And also, if its a good tune it should be fine. as long as you don't change anything you won't need a retune... IE sell the t70 and go to a t28. You'll def need another tune for that.

1st off wow at your avatar.. secondly i agree because im not shooting for any higher power.. i jus want a daily driver.. turn down for me is that i take the turnpike to school and will be tempted to boost 8-/.. and boost some more...

nice tip on tuning... I agree with you there. As far as putting a T28 on a KA 24?

WHY????? That turbo will barely flow enough on a 2.0 liter. The T28 will not make much power, might help a little on the spool but you'll be at 230-250 hp range all day no matter what injector you use. I recommend a turbo that moves a larger volume of are at a lower psi.
Sure a T28 can make 350 hp at 28psi or whatever, but KA engine will not hold that kind of psi - with out major work.

BTW I use stock injectors and a BEGI fpr with a t04b in combo to make 258rwhp at 8 psi. No tuning/afc/etc needed. just a good old fashioned wide band o2 sensor and a fuel pressure gauge.
