i had a t25 set up on a 85k stock block with sr injectors fmic tuned ecu stock MAF. i loved it ran a 13 @ 106 on slicks spiking at 10.6PSI had a electronic BC. if you have perfect compression do it. if its done right an not using cheap parts then you will have a perfect turbo DD like i did never had any problems and spent about 1700$ on the set up. but if u do it dotn run high boost all the time keep it down if u wanna keep a workign engine. an after 3 weeks i got tired of the t25 an was planning to buy a built KA an do a top mount gt28, its fuckign addicting.
