Having recently gotten back into the DSM game I was disappointed to discover the OEM thermostat is no longer available. The main reason for running an OEM thermostat is that it had a larger opening than aftermarket thermostats, theoretically allowing more coolant flow when required.The 1990...

This is the Build Thread for 1990 FWD GS Turbo. Reply below.

Took the car out two weekends ago just concentrating on getting it to leave properly. Gave it all she had on the 68HTA. Power was down all day so hopefully I can find out why and try to get my 125+ mph traps back and try to dip more south of 10.8. Profile should be up to date.

I know all the numbers to enter on this page: Racing Calculators - TCI® AutoExcept the rear end ratio. There is another reduction done inside the trans after the planetary and before the final drive. I think this is what is messing me up. If you put just the final drive in you get some...

Made some small changes (read: free) and the car broke into the 10's after running consistent 11.1's the past 2 years. I mainly bracket race, but bettering the ET is always nice.Car is a 1991 GSX-5 speed converted to auto -kiggly manual shift mod -Bridgestone RE01R tires on Evo 17"...

I am posting this for a friend who has been trying to fix this issue for over a year. I will provide cliffnotes at the end if you don't want to read through the whole next paragraph.The story starts with a 1990 GSX 5 speed that had no vibration problems. We then put a DSS 3.5" driveshaft in...

Went to the track last night for the last time this year. I had an issue with my injectors clogging on E85 so I swapped in a different set from my evo and decided to just run 93 octane. This was the only change from struggling to run 11.70's at 124 on E85. I got the hang of doing burnouts at...

Results were 420whp/350tq. Boost was 26-27psi tapering to 23-24psi.

I was wondering if anybody has the shim sizes and the corresponding Mitsubishi part number for the intermediate shaft shims on the 1g AWD W5M33 manual transmission.thanks, dan

Drove 65miles to beaver springs dragway in pa today and immediately ran a 12.1 at 122. The best I could get it was 12.0 at 122 a few passes later. It got up to the low 80's or so and my MPH dropped and I couldn't ET any better. Their was a big wreck and I packed it in and headed home...

Finally did it. Stock longblock with ARP's holding the head on (kind of).

I'm away from home at the moment going through some of the pictures of my cars that I miss. Here are a few of my favorites.

I'm sure a bunch of people had their personal bests at Norwalk this past weekend. Thanks to Dave and all the sponsors, it was a great weekend.I was originally going to drive out, but my buddy hooked me up with a covered trailer. I made about 7-8 passes and ran two nearly identical 11.5's...

This is the last place I'm going to put this. The car is a 1990 FWD GST 5 speed with 160,000 miles. The motor is origional w/balance shafts removed, ARP's, MMHG, and new OEM valves and reground seats. The tranny is the origional w/open diff. Stock intake manifold, head, and throttle body w/no...

Sharing on this board incase people don't check both. Got a chance to make it to the track yesterday after mostly solving some ignition issues. With half pump and half race gas I got to make some clean high boost pulls. Ran a bunch of mid 12's at 123. Got a 12.5 pass at 124.7 mph. Then after...
