Computer, Fuel Pump, and Injectors.

[whatup]

I purchased an EP91 from a friend with a K24 turbo kit on it. I was thinking about upgrading to a K26 turbo, but for now I will see what I can get out of the K24. The problem with this car is that it came with a stock computer, fuel pump, and injectors. I will definitely need to change the computer since it gives an aweful bog/jerk at high rpm on full throttle. Will I need to upgrade the fuel pump and injectors? If so, what size fuel pump and injectors will I need?

Get some pics up of your setup. i would have imagined that you would have needed bigger injectors, how is the fuelling being controlled? sounds like you are hitting fuel cut, that would be the bog/jerk at high rpm.

sound like your hitting fuel cut

for a k24 tubby you would defo need an after market ecu also a walbro pump and injectors as they would be reaching 80% plus duty

but sort out handling and braking before power as anyone on here would say

The fuel is currently not being controlled. If I buy a e-manage to solve the fuel cut, what size size injectors will I need. We are talking below 500cc right? I am currently working 2 full-time jobs for 10 weeks, but if I get a chance to take some pics of the engine bay, I will post them.
