- Background
- This is my friends 1997 Spyder GS. I work as a private mechanic and since my friend got the car in fall 2013 he has wanted to upgrade it. Through determination he saved enough to do just that, starting with the engine. It started to have a lot of problems, mostly auto transmission related, but with 230k miles on the engine it has run its course.
The plan was set into action when a 1995 gst manual was purchased with a blown headgasket.
This car was completely stripped, parts needed kept and not needed sold. Ended up being a great deal.
We are starting with a fully built block and head with only light outer mods. Stock cams, tuning and fuel delivery for now. First upgrade after the car is running will be EPROM computer and ECM link, then fuel delivery, then turbo. Do it right I say.
Then he will need to go AWD to handle the power ofc...
Project officially started with planning and purchases March 2014, engine pulled July 5th, car is hoped to be running by Aug 2014.
*Very close Sept 21st... Lots going on in everyone's life amazing car is getting worked on at all but we are pushing through it.*
******NOV 12th 2014 AND Literally a few hoses away!******

****** July 26 2015, engine rebuilt and dropped in, bay painted . 20g turbo ecu+ and lots of upgrades *******
****** Aug 20 2015, screwed on 2 turbos, now running a used something 16g, car runs again. ******

****Dec 1st 2016 Car has been down for a few months, only 3000 mi on the XTD 6 puck and it took a crap. Mostly due to weak pressure plate and failing/unadjustable master cyl. Has new act street disk and new OEM master and slave, back to running.*****
