How far can an sr20de maf be pushed before you should upgrade? Thinking of a t25 with s4 cams.

I have a friend w/ a Stock ECU, MAF running S3 cams, and a T25 with no problems. The car doesn't go about 7 psi, so I don't know the limits of the MAF.

Ben, is this guy doing this on stock 259 injectors???

About as far as 370cc/min injectors can be pushed, which was about 220 WHP, I thought. You can also get one bored at JWT, but I don't think that's a cost-effective idea when you can get a Z32 MAF for so little money. I think the MAF will be fine, but I'm an idiot.

thanks for the info. I don't think i'll be passing 220 hp on the first go round. I'm a fool with turbos so any info is helpfull.

Try upgrading to Q45 injectors also. A jwt program wouldn't be a bad idea either.

Get a standalone andwont have to worry about nothing besides paying for it and getting it tuned:D
