Lexus air flow meter swap?

supracurtis · 02-10-2009, 06:58 AM

I have been reading that you can use a Lexus air flow meter in the 89-92 turbo supra. Just wondering if anyone knows what model Lexus and whats all involved with doing that.

lexus V8 meter used with 550 cc injectors to fool the FCO (fuel cut off) by adding 25% more air and 25% more fuel .

How big are the stock injectors in the turbo and the na? and would 680's work or do you specifically need the 550's?

Also, would I need to mess with my computer to run either of those injectors?
