Fuel management problems!

[AlexStunts.com]

Recently purchased a 240 with the RB20det swap. I have used the search function for this particular problem, and could not find any info..

When the turbo spools up with boost set high at 14psi, the car has a major sputtering. Not sure if I have a stock fuel pump and injectors?
If I have a stock fuel pump is this a problem???

What can I do, to trouble shoot this problem????


Thanks in advance!!!

Stock fuel pump is definitely an issue.

You need to upgrade this. You are most likely running lean and this is very dangerous to the engine.

Debo its not the filter ahahh, starting to figure this crap out, bought a eprom off ebay, takes all the stock cuts out (fuel/ boost) added some horse for sure, ordering 550 cc injectors and upgrading turbo, then I'm getting the car tuned profesionally, should be a runner
