Blog Title: 1g Non-turbo -> Turbo swap
This is the journal of my 4G63t 6 bolt swap into my 1991 Mitsubishi Eclipse GS.
My car: My Eclipse was my first car, I was 16 years old when I got it. I bought it on January 2, 2003 for $250 with a free tow to my house. The timing belt had snapped at 114,000 miles and destroyed the head. Also the front bumper and passenger side fender were smashed in. Other then that it was in great shape. My dad and I rebuilt the engine from the head up. It took us 4 months but when we finally got it started that Easter it was an awesome feeling! This car has been my daily driver ever since, for the last 7 years.
My engine: The engine is out of a 1991 Plymouth Laser RS Turbo FWD car. I acquired the engine, transmission, ECU, and wire harness out of the car when it arrived at a junkyard, where I worked at the time. I pulled everything out in 1 day. I had the engine rebuilt to factory standards and attempted a swap back in 2005. However I ran into problems with the engine, with money, and with it being my daily driver and ended up pulling it out and putting my GS engine back in. My turbo motor has been sitting on a stand in my parents garage for the last 5 years.

After finishing my engine swap, my goal was to have my car ready to race by the Texas Mitsubishi Shootout at the San Antonio Raceway. This gave me about 45 days from the time I first started the new engine. I had to break my block in (1,000 miles) and iron out all the wrinkles (so to speak) so that I could make some reliable passes at the shootout.
The break in went well, I got all my miles in with 2 weeks to spare. However I had been have a problem with boost leaks and a weird noise like a siren which I suspected to be my turbo (I was correct). Boost leak tests reviled that I was leaking from my lower injector seals, fuel pressure vacuum line, and what seamed to be the 14b itself. I replaced all of my fuel injector seal with FIC's complete injector seal kit and tightened up my vac lines.
My turbo wasn't quite so easy. It was leaking boost, making strange noises, and had some in and out shaft play. With just 14 days until the shootout I ordered another 14b from the classifieds. I received it and installed it with just 6 days to spare. This didn't leave me any time to practice my launch with a front wheel drive turbo car, it would have to wait for the track.
Saturday arrived and I loaded my car on a trailer (My first time on the track with a new engine, I figured a trailer was good insurance) and drove 9 hours to San Antonio.
Sunday morning, track day! My first pass I launched at 4,000 RPM's and spun like a hamster on a wheel. My first run was a 17.6 at 95 MPH. However after 10 passes I had gotten down to a best ET of 14.3 @ 101 MPH. I was running 14 psi on a 14b with stock injectors, stock SMIC, full interior, and street tires. Here are all of my passes in chronological order:
60' ET MPH
2.8 17.6 95.5 (Launch at 4k, spun all through 1st)
2.7 14.7 101.9 (no launch, best MPH)
2.8 15.0 100.6 (launch at 3k)
2.5 14.6 100.6 (started launching at 3.5k)
2.3 14.4 99.5 (best 60')
2.5 14.7 98.8
2.6 14.9 89.2 (on the brakes, I had 0 boost on gauge, blew my gauge line off)
2.6 14.7 101.5
2.4 14.3 101.1 (best ET)
2.5 14.6 99.7
Spinning tires off the line on my first pass
My goal was to get into the 13's. I know my car can do it, hopefully next time. I'll shed some weight and work on my 60' and I'm sure I can knock off that .33 of a second and get into the 13's. Even though I didn't get it in San Antonio, I was still happy with my car. It performed great considering this was it's first day on the track with this engine.
Stay tuned!!!

Nice!!
Car definitely has a 13 in it, saw your runs and wouldn’t have guessed it was a stock 14b turbo.
Thanks for making the trip! Goodluck with the 13's!Posted 06-21-2010 at 01:55 PM by DSM_PWR
