1981 Celica 3SGTE rev issue

[draxot]

My drawn out project is coming to an end. All the running gear and engines working fine BUT:

When i give it some gas around 2.5k revs it splutters/farts and kinda cuts out. I have a feeling/ been told sometimes the Automatic ECU needs to be bridged into neutral mode.

 

Maybe i get a manual ECU as i really cant afford getting a Link computer at the moment.

Are there any suggestions or thoughts?

Much appreciated.

Fuel/boost cut?

Stock turbo/boost?

[draxot]

stock turbo, (cut and flipped around) so a little more restricted. Boost hasn't been messed with (so i think about 7PSI isnt it?)  -How do you set boost cut in a factory setup?

 

It has old 91 fuel in it but not too old. Running a v8 commodore pump..

Also, is there a list out there somewhere of LSD diffs that would fit an A60 1981 Celica?

Are there lists that show the interchangability of toyotas? :P

You will need a fuel cut defender.

You may have other issues as stock boost shouldn't trigger it. Make sure there are no issues with the ignition system as well. Rotor and distributor cap are worth checking.

Thanks for that, i still need to do more research on the boost cut defender. Is it as simple as buying and installing yourself?

 

The problem was a blocked fuel filter/ fuel pump was dropping its pressure when revving up. Got a new walbro pump and new filter..

If you are relatively handy, yes.
