OKAY I JUST INSTALLED MY TYPE R FUEL PUMP ! i had a DX fuel pump b4 .. and do i need to change my injectors-ecu in order to run more fuel ? cuz rit enow i have GSR 240cc injectors-ecu well that regulate against my R fuel pump ?

 

several ways to get more fuel

a. electronic (ecu or piggyback)
b. injector size
c. pressure regulator
d. fmu (if you are boosted)

How do you know you need more fuel?

 

in low or high rpm car wont go ! feels like shit... now i got a FUEL pump when i hit vtec it works better ! also iam gonna get a FPR ! B&m hope it well boost my performance. thanks for the tip 8)

 

Type-R injectors are 240cc. No need to change yours. Check your timing.

 

 

timming is on the money .... but i retard timming to 14 so could that be the problem >? :twisted: :evil:

 

hmmmmmmm I don't know OBDII tend to fix the timing on its own......

 

change tyPE R injectors-and using HOT PLUGS fix the problem a lil bit in high end it RIPS - and in low its kinda of boggys stilll... damm ... well iam getting my s200 this week and getting it pogram this week ! iam going to try to get my car dyno this week ! keep u guys posted on my results.

 

Here is a dumb idea,,, Have you cked the gas filter(s) lately?

that could hold up your gas flow

 

Also, if your timing is at 14 degrees, that's bad, there is no reason unless you're boosting on pump gas that you should have to back your timing up that much. I was running just shy of 13:1 compression with 15 degrees of timing in humid/hot south florida weather, and it still rarely pinged, even under a lot of load.

Fuel pump really doesn't require any sort of modification, they're basically plug and play. As far as injectors, as Trey said, yours are fine. Also, you mentioned that your computer was a GS-r computer...what type of intake manifold do you have, and if it is a GS-r, perhaps the manifold butterflys are stuck...not likely, but possible. Also, I'm assuming that you got the injectors used or with the motor, did you ever get them cleaned and balanced????

I'd start with the timing, try putting it back to stock, which is 16 degrees. If anything on a relatively stock motor, you want to advance the timing, not retard it...Work from there...

Later,
