    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!******

    See all the pre planning and parts car here.


    ****** Car was running in Dec, but a few delays and now Jan 20th 2015 it is on the road!*****

    ****** May 25 2015, Oil pressure sensor cracked and friend kept driving it even seeing oil press dropping. Had to cut the crank .25mm and redo bottom end.*****

    ****** 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. ******

    ****Oct 1st 2015 After buying a new 20g from Justin it is running good again finally.***

    ****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.*****

    Long time no updates. Cars been down for a few months, crap xtd clutch toasted its self after about 3000 miles.

    400 miles on a used act 2100 pressure plate and a new act street disk. Put in a new spec clutch fork while in there. Cheap XTD Flywheel was slightly warped but no money for a new one. Put that all in and it would not go into gear well and no reverse.... New OEM master adjusted properly and new slave cyl later and good to go. Both were less than 2 years old but autozone parts....

    Soon will put in all new act clutch and fidanza flywheel.

    Waiting for break in to be done and back to tuning the issues, I think I need to pull timing and fuel...

    is that pretty much plug and play or what did you have to change?
  11. agarcia
    When you installed the gst wire harness, Dios you Jane trouble connecting it to the 4g64 fuse box?
    1. darknezz7
      Honestly I have not gotten to that. Doing a ton of beauty work to the bay first. Cant be too hard to splice if needed though.

    Car is at my place finally, In a day the head is off, axles out and block is ready to pull and be dissembled tomorrow.

    Last time it will look like this.

    1. darknezz7

      darknezz7, Jul 6, 2014
    2. agarcia
      I'm attempting to do this now, i am using the gst harness but cannot connect to the engine fuse box, both are male plugs, how did you manage at this point?
