So I'm in the middle of pulling all the turbo bits off an 89 760 turbo I bought for way too cheap to put on my 86 244 w/ M46. I've decided to go +t on the 240 instead of swapping because I'm using the car for rallycross and I think the better throttle response and quicker spool of the higher compression engine will suit my needs better. The 240's engine only has 149k miles as opposed to the 225k on the 760. The 760 has a build date of 9/88 and is LH 2.2 and has the Garrett T3 (most of this info is for someone else's future reference)... I got lucky with a simple swap. I plan on moving over all the turbo bits, feeding oil from the sender, draining into the oil pan, and using the 760's fuel rail, FPR, injectors, intercooler, ECU and timing computer.
A couple questions for those who have done this before. How much boost can I safely run on the B230F without running lean up top and without detonating? Has anyone here done this with a knock light and wideband and knows for sure? I know these engines are a dime a dozen but I'd like to avoid popping it. I don't feel like I need to make any more than 250hp in this engine, and I'm fine with whatever it makes safely until I go MS.
Thanks in advance!
