stocks are 240's if memory serves.
I wouldn't put anything smaller than 440's on a turbo honda personally

Im thinkin about when I do eventually turbo my car, to run Trust turbo and intercooler, Tial wastegate, Full-Race manifold, and either PRO-ECU or hondata. And prolly a custom 2.5" exhaust with a universal 2.5" muffler, a'pexi or fujitsubo, fujis sound really good..., 550 cc injectors, and I dunno, some kind of boost controller... havent thought about that much
I Wonder if Saxman is ProECU's other login name for ozhonda.....Quote:

no thats ok ive spoke with a few tuners worldwide
they say its ok to push the car round bout 7 psi max without changing injectors or computer all you have to do is force more fuel through the injectors(h22 preludes do it through standard injectors and run fine and they are 2.2l Ltr) to do that get a bigger fuel pump and a regulator to keep the injection stable.
if you push it more then 7 psi then injectors and rails are needed as well as a bigger wastegate which is about 50mm.
basically its safe if your after a quicker car but if you want better ET and Kw then thats when internals will have to be added in
whomever told you that doesn't have the SLIGHTEST clue what they're talking aboutQuote:

To properly fuel for most normal sized turbos, you would need about 90 psi of fuel pressure on top of stock fuel pressure to squeeze enough fuel out to properly support that air flow. About 130 psi for a system designed for 40ish... not good. Also, you have no timing control. Running stock timing at 7 psi is a VERY BAD idea.
Also, a 50mm wastegate for 7 psi? Please. Also, the stock fuel rail will support at least 400whp... you certainly don't need to upgrade it for more than 7 psi.
whomever told you all that doesn't know his head from his ass. No one who knows the first thing about tuning would ever recommend just bumping fuel pressure up.
This might work. I wouldn't do it this way personally, the cost of a regulator + pump + install would more than likely cost more than replacement injectors.Quote:

can you imagine how much smoke you would billow out the back of the car running 130psi of fuel pressure at idle/vac/low boost?Quote:

yeah, i'm assuming there's some kind of injector pulse width adjustment in the mix somewhere.
In any event, its not my preferred method.
i'm running a low boost setup on my crx with stock injectors and nothing has gone bang yet, they just have a hard time keeping up thats all.Quote:

Take it to a dyno to get this measured for peace of mind.
don't worry, give it time... it'll go bang soon enoughQuote:

not that anyone running stock fuel injectors is very likely to have anything to control them with anyway.
