Looking to build a Proclimb 1000 turbo and have most parts and pieces to do so with a pump gas turbo setup . Have always used 30 series Garretts on 1000 engines in past and 28 series on 800. Has anyone used the 28s on M1000? Looking to do lower boost application with 10lbs max as that is what I was able to run in past on my builds with pump gas use and timing control. I have 3 28 series Garretts right now and no 30s and was looking for advice from the turbo gurus here on using the tighter exhaust side on the M1000 for lower boost. I have a 2863, a 2871 and a 2876. I am leaning to using the 71 or 76. I have a Boondocker box and a PCV boost with secondary injector module. Leaning to using PCV as the Boonie box is programmed for M8 and not sure if anyone can give me new starting numbers for the 1000 setup.
