Re: MAP sensor / injector swap - what do ppl think?

Cheers for the reply man.
Yeah im using the factory 7AFE ECU...
I got my hands on a well priced malpassi on the weekend, and can get a ZE fuel pump very easily... so I might go that way in terms of fuel pumps. I asked about an MR2 turbo one at wreckers here and they wanted $250 for it!!! (Wreckers in NZ are such a rip off!).
They seem to make and sell 7AFTE kits. Down the bottom of that page they suggest using a 2 bar map sensor and larger injectors... Now if the MAP sensor is only supplying a voltage to the ECU to tell the computer to look up that voltage on a chart which then instructs the injectors to pulse at X rate, then if you installed a 2 bar MAP sensor and injectors to match that sensor (it might be hard getting exactly the right size injectors, but i am assuming someone has tested the 320cc ones with the 2 bar sensor as suggested on thet JGS tools site), then it basically should run almost as if it were a factory setup. (of course i may be fooling myself here and in reality it may not be that simple. One problem i can possibly forsee is that there will be too much fuel at idle)?
Re injectors, I dont think i can use the 365cc ZE ones as they are low impedence. My fact ones I am led to believe are high impedence I think without buying an aftermarket ECU anything substantially larger will just be providing way too much fuel. If only i could get my fact computer re-programmed.. apparently it aint possible though.
If i can get my hands on a 2 bar MAP sensor and a set of 7MGE 320cc injectors cheap enough then i mite give it a try - will be an educating expreience if nothing else.
