Title: 1988 tc
Post by: jonwayne1988 on November 29, 2011, 10:57:35 PM
I just bought this tc for 900 buck today. It needs some love. It got so wiring problems. Some one cut the wires for one of the fans and wired it to a switch so now I need to put it back to stock and figure out what is wrong if anything. Some one also cut a hole in the IC and put a blow off valve in it. At lest I have a spare stock one to put in its place. I think I will be needing a fuse block. One of the spots for a fuse is melted.
Well more pics to come if it before I start any more work.

Here is a pic of a blow off valve some one put on the car. After taking it off and putting a stock intercooler back on it it starts up a lot faster and runs better.

Yeah, I'd been watching it for awhile myself...save it. Fix it, and enjoy it for years :)

Well looks like I found a few more things. One is this vacuum sensor. I need one and I need to know where it goes to. If I remember right it goes vacuum source to one side the out the other to the turbo. Is that right? I also looks like some one did the 3g alternator upgrade. But the amp meter does not work.

Bypass that BCS (Boost Control Solenoid).  Just use the gillis boost valve and DON'T reistall the BCS.

Will bypassing it make the check engine light come on?

Right now it is just bypassed. A vacuum line is going right to the waste gate. Any ways what does that gillis valve have to do with the BCS. What to you do leave the BCS plugged in and take the vacuum lines form it and put it gillis valve.

Ok well yesterday I started removing a bounch of very poorly done speaker wiring. They had used jumper cable wire for a amp power wire. They also had speaker wire, lamp cord wire, and regular strand wire to run all the speakers. It looked horrible with all this wire just laying allover the floor so it had to go. After removing it all the dash lights won't come on anymore.

k so I got a boost control solenoid. Does it matter witch way vacuum lines come in and out of it. I know people say bypass it and use something else. But for now I just want to get everything working right first.

didn't even see this, but i believe it does make a difference.. i don't think it'll function correctly if it's hooked up backwards

Welcome, looks like a great car to build on. 

The Gillis valve posted would serve as a replacement for your BCS as they both are a means of controlling boost.  I understand you just want to use your stock BCS for now.  I don't think it matters which hose goes to which side.  I would just hook the hoses up and go for a test drive then try both regular and premium settings on your fuel switch.  The regular setting should give you about 10psi and the premium should give you about 15 psi.

As far as the dash lights go, did they work before you removed the speaker wiring?  You may have pinched a wire when messing with that stuff.  Here is a link you might check out.  http://www.coolcats.net/help/dash.html

OK question If i use the Gillis valve do I still need to have the BCS hooked up for the computer so it wont have a CEL? And I got the lights working it was just a dirty dimmer switch.

i'm going to have to say no.. my new tc is basically stock with a gillis valve and the CEL doesn't come on, nor do i have any 'hidden' codes

Ok I have still been fixing wiring and such but still can not get the clock to come on. I have plans on putting the gas mileage computer in but need to make sure it's going to be getting power first. All fuses have been checked.

Post by: Shadow on December 11, 2011, 09:42:51 PM
maybe the clock is shot :dunno: i'd pull it out (if you haven't already) and check the wires going into the back side of it.. i always check fuses, then start probing the problem area, which in your case, is at the clock itself

BCS doesnt turn on CEL will only set code in KOEO and KOER tests.

Post by: Shadow on December 12, 2011, 12:34:48 AM
mine is still plugged in.. tomorrow i'm going to start cleaning up under the hood and going to disconnect it.. we'll see if she throws a code without it ;) but somehow, i doubt it since it's not doing anything without any vacuum lines hooked to it
