Cant wait to upgrade my Supra to an Igition system with Points.

There are NO upgraded fuel pumps. The Dorsch pump is for the G1 platform that runs a 20MPa fuel pressure. The supras use a 35MPa system. This is not compatible. And even if it did the injectors on the supra would run short at high rpm. Port injection with Motiv is the only good way to do proper fueling beyond the stock setup.

A lift pump can also help as the fuel pressure does drop a bit.

EDIT: Just realized this was an old post. I guess I need to share that bottle with Marin...

Incorrect. G2 pumps are out. So are injectors

FYI Supra owners manual says up to E25 is okay.

And that’s more for what the ECU can handle on the stock tune.

FYI, I did five track events last year with E20 and the stock tune. Logs were just fine.

Almost all normal gasoline is already E10 if people weren’t aware.

The lines themselves? They're at least good to E95.
