Here is some Dyno #'s - 364 RWHP and 500 Ft. of Tq. MY clutch is slipping badly. So The numbers are quiet low,
Compared to what it actually is.
The 50 AE was pretty fast stock, but not fast enough for the local competition. So a few mod's were needed, or so I thought. It all started with a simple boost controller. It worked well until pieces of the turbo went through the motor like shrapnel from a grenade. Hey a motor with 90k miles is not going to hold 12lbs of boost for long intervals. After that I went car looking and bought a Honda DelSol so I could have something to drive while I started on the massive rebuild of a high performance turbo motor. Which the whole process took about 2 years to complete, because of time and money, but mostly money.

The motor was pulled out and sent to the machine shop. Once there it was bored out 0.25 over. Then the next thing was to find some forged pistons that would fit and handle high boost pressure. That's when he recommended using a Wiesco forged pistons from a Buick Grand National, which could easily handle up to 30lbs of boost. Keep in mind that in the mid 90's there wasn't a whole lot of support for import cars, especially when you are talking about internals. Then everything was carefully assembled back together being balanced and blueprinted as it went together. The heads were ported, polished, and a 3 angle valve job was done along with o-ringing the block. (Less chance of blowing a head gasket.)

The next thing to carefully consider was a turbo. I wanted one that would provide a lot of boost while not giving off massive amounts of heat, and not requiring 2 miles to spool up. So I went with a custom ball bearing T3/T4 hybrid turbo from Turbonetics. After frying 2 stock clutches, I decided that a center force duel friction clutch was needed to handle the extra horsepower. A 3" custom mandrel bent exhaust, from the turbo back. The center pipe and manifolds were also ported and polished. A high flow cat was added for obvious reasons. Now with all the extra power and a very light rear end, 245/45R16's were needed for extra grip and added traction on wet roads. I also had a custom drive shaft built for the car that weighs 4 lbs less and has stronger u-joints with grease able fittings.

A Spearco intercooler kit was added for cooler intake air and safer boost levels. I am currently running 18psi on the track and 16psi for normal driving. I used a blowoff valve from a Mitsubishi eclipse, to keep the turbo spinning in between shifts. I then had the throttle body ported and polished along with the intake manifold to get to lessen one more air restriction and to get faster throttle response. The stock clutch fan was removed and replaced with an electric fan to lessen engine drag on the accessories. An alternator upgrade was needed to keep everything charged so I installed a "91" Maxima alternator which puts out 90 amps compared to the stock 70 amp alternator. I then installed a lean/rich meter to monitor the fuel/air mixture. I also installed a fuel pressure riser that raises the fuel pressure with boost. A short throw shifter from a Ford Mustang was used to shorten the throws for less down time in between shifts. A bypass oil filtration system was added to increase oil capacity and to keep the oil much cleaner. I have taken it to the track only once and ran a 13.4 in the 1/4 mile. The car did nothing but spin the tires in fist and second gear, with a MPH of 107. Keep in mind that I am not so good at Drag racing (1.3 second r/t). I hope to get some slicks and turn a time somewhere in the 12 second range.
I am now on my third transmission. I have put some performance stuff in it. Unfortunately I can not say what was done to it because I had a guy at a local shop who builds transmissions for Mustangs. He has a few secrets that he dose not want to let out. I have gotten an LSD from an "87" turbo and what a difference it made. Tires spin a small amount but it mostly just bites and goes. I have just installed an MSD BTM (boost timing master) and it makes a hell of a difference on the way the car runs. Smoother idle, more power, and faster starts. I should have installed it sooner. I also have installed a HKS F-CON.
Well some how I destroyed the LSD clutch type differential. Everyone says it is bulletproof but I guess if you make enough HP anything is possible. I have gone to a VLSD from an Infinity J30. With a gear ratio of 4.10 Vs the stock 3.70.
Well after doing a lot of running on the local 1/8th mile track. The car has no pull until it gets almost to the finish line. So now is the time to do what big V8" have done for years, adding NOS. Sounds fun doesn't it. The 80 BHP shot gets the car off of the line really quick.
