MHARPER1 0 Report post Posted June 7 I am thinking about installing an MMI Twin Turbo Kit on my truck. It already has a 4L80E transmission. The kit is on amazon. Anyway, what I am wanting is help on what else I will need to buy with the kit. I know I will need bigger injectors, I just dont know how many lbs/hr. I also plan on installing a high flow oil pump with this kit as well. I will be getting it tuned on a dyno after the install. I also plan on replacing the head gaskets, intake gaskets, and lifters at the same time. Thinking about a cam, but not sure where to go with that either. Looking for any advice that I can get. I am wanting to put around 600 horsepower to the ground. Not trying to get too crazy with the boost. Share this post Link to post Share on other sites
fattybell 7 Report post Posted June 7 (edited) a 450 pump and deka 80's will probably be maxed right about your goal on pump 92 . BUT if you think you will want more build the fuel system for more now! 2 450's and 210 injectors will support your goal on e85 and have room for more. I myself am looking at a little john motorsports(LJMS) stage 2 turbo cam. I am only giving advice on the research ive done. I am by no means any kind of "expert". hope this helps Edited June 7 by wantaSSS Share this post Link to post Share on other sites

So I think that the 450 pump and 80's may be the best route. I'm really not trying to go crazy with it. I still want it to be reliable and not blow the engine.

fattybell 7 Report post Posted June 8 (edited) I run only 92 myself not ready for e85 yet. I am running 8 to 9 lbs of boost and am using a 450 and 80's and still have room left . So it seems if thats what youre looking to do then a 450 and 80's will work fine. I ran a -8 feed and used the stock feed as my return line.
