Hey all, long time lurker here. I picked up an SPI 2.0L Mercury tracer (auto) for $350 that had the classic valve seat failure. I'm going to buy a new head (mines waaaaaay trashed) and a new piston for the bad cyl (#4) Everything else checks out fine. Engine has 176,000 on it, and has 150ish psi on the good cyls. The car is in otherwise great condition, and would be a PERFECT sleeper. I'm looking to turbo this engine, and bump the power from the 110hp it has to somewhere near the 200hp range. From research, the rods and pistons are up to the challenge, and the rest of the engine for that matter. I want to keep my ECU stock also. I want to be able to drive the thing normally, and on occasion be able to mash it and have some power. I already have a good T3 off of a turbo dodge caravan (2.5L.) I'm thinking of running a 5th injector setup (or staged additional injectors) for fuel management. The stock ECU apparently wont run timing too advanced under boost conditions. The 200 number is just a number. It's just gotta walk a 90's v6 (3.8l 200hp) stock camaro lol

Tell me what you think! I know a piggy back or standalone with bigger injectors would be a better solution, but when out of the boost, I want it to run completely stock with no bad idle, over-fueling or any other inherent modification problems, or worries about who tuned it. It'll be getting all the gauges to monitor everything also.

I'm not even opposed to running some water injection to kill the worry of pre deto problems. I basically want a cheap, homebrewed, workable turbo setup that'll pour fuel to it under boost, and shut off when there's no boost (and drive normally.)

Opinions?

 

Bro I have a mercury tracer and I was thinking the exact same thing and I’m so excited to get this build going
