1988 Toyota Celica GT4 Computer box

I have a 1988 Toyota Celica GT4. I'm having it fixed in a local mechanic. We were experiencing a lot of issues with this car.
When we were on to the wiring, we found out that the Computer box's code was 3S-GT which is different from the engine code 3S-GTE. Will this affect my car's performance? Also, I was planning to install gauges and turbo timer. Will my computer box able to support the said add-ins?
We are also planning to take off the catalytic converter and directly place the exhaust to the headers. What benefit will I get from it?

There is no problem with your computer box, it says 3S-GT on it, thats the way toyota did them back then. same with the 3S-FE (says 3S-F on the comp. box) and 3S-GE (3S-G on comp. box.) i dont recommend removin the cat. you will get defected (or waht is equivelant to a defect where you are) due to smog and stuff like that. Turbo timer is wired to the igntion system, no problems there. and as for gauges: get a pro to install them, but there should be zero trouble.

Car having prob starting, having to jump start it. Got an ignition unit but it was not that. When driving my 17yr old celica gt4 it feels like it is losing power

There are lots of issues that might relate to the engine not firing and must be checked. So start by checking on the fuel, the fuel filter, the fuel delivery.
next check on the firing , the HT coils the spark intensity. Check the coils and the timing of the spark.

With no key your best bet is to call a local come out and make a key then you won't have to change all the locks and ignition.

Sounds like a timing issue. The best thing would be to pull the trouble code from the computer since the check engine light is on. If you do not have access to a code reader then start by checking the timing order and the spark plugs. If these are OK then check the distrubutor cap and rotor. Check the cap for cracks and corrosion. If everything is still good, then you may need a camshaft position sensor if the car has one. If the car is not equiped with the sensor, you may want to find a new or used distributor.

Head gasket gone

Yes. It's a real pain in the ***. You're going to have to remove the intercooler from the top of the engine. Just be glad it's an air-to-air intercooler, not an air-to-water "charge cooler" like mine. Once it's off (pour some gas in it and swill it around to give it a bit of a clean), you can start getting the bolts out to get the head off. Take the spark plugs out first. I don't *think* you need to remove the inlet manifold on this car.

For further help & advice go to You don't have to pay for a subscription, there's plenty of resources and if you post nicely in the free area someone is bound to lend a hand. If you're going to be doing a lot of self maintenance on your GT4, it's probably worth the $$ for membership!
