Hey any one know how many CC's are the standard injectors,cause my ones are starting to leak . I wanna replace them with the same sized one's

Don't wanna burn valves

Nissar my understanding is that the stock GTV6 2.5L injector flows 19.5 lb./hr.which translates to 205 cc.

Nissar CORRECTION I made a mistake (very rare - just ask my wife ) The GTV6 2.5L injectors flow 17.5lb/hr not 19.5 as stated before, so that translates to 184 cc/min.

Important also is the fuel pressure that the flow is measured at. The GTV6 has a odd pressure setting compared to most other cars.

Does anyone know what that fuel pressure is?

MR2 Zig nominal fuel pressure from the AR shop manual is 35.6 psi / 245 kpa / 2.5 bar

I had mine flow tested. It was around 186 cc/min at 43 psi. So with 37psi on a Jetronic the flow rate is a little lower lower.

I knew the flow rate was dependant on pressure....tho I didn't know what that pressure was and I thought the OP might not have been aware of that facet of specifing new injectors.

Thanks Z!

Thanks Guys Im gona try and get around 200 cc's

For 200 bhp you may not have to upgrade injectors. Just put a motronic regulator from a 164 or something inline with the return hose. That will give you the 186 cc/min. Going to 37 psi won't make the flow rate decline so much. There is a forumla for it, somewhere I think RC injectors has a formula for it. If you reduce the fuel pressure by 10% you will lose far less than 10% in flow rate.

I've got 17.6lbs/hr @ 36.5 written in my notes but I'm not sure where that came from.

The formula is:

[ sq. root(new pressure/old pressure) ] x old flow rate = new flow rate

Also,

lbs/hr x 10.2 = cc/min
