first off let me just say...thanks to all that helped me get my car back up and running (the car that wouldnt stay running.......havent fully fixed it yet).

But now i have a new problemb, once its running for a while the turbo heats up and glows red HOT . just wondering if anyone has any idea why its doing that...i may have an idea of how to fix it but i was just wondering if anyone knew for sure how to fix this.

 

what are the mods on the car? could be running rich/lean or could be signs of cat/02 problems...

what ecu are you using.

 

everything is stock, the only mod i did was painted the calipers black and painted the boot or shoe red.

i do plan on modding it but i need it running right first

 

If the car still has the stock pre-cat, it could be somewhat clogged. If I were in your shoes, I would just take this time to replace the exhaust:

Bonez downpipe & hi-flo cat. I ran that setup with a Greddy catback for many happy years.

 

Your exhaust must be backed up. Remove the Pre-cat and replace it with a downpipe ASAP. It may help your other problems also. The full exhaust is great, but install a boost gauge to keep an eye on over boosting.

 

The turbo would overheat if the coolant or oil wasn't flowing properly but that seems unlikely unless it is leaking all over the place or out the exhaust.

 

i may try that, i disconected it earlier
P.S. my other problems are fixed.

 

Ditch the pre-cat asap.
