88 Coupe Boost Question

Hi all, I am in the process of buying a 1988 TCoupe and I have a few questions. The car is all original with the exception of swapping out the Auto for a T5. She only has 52,100 miles and is absolutely beutiful. My question is, do I need to get an ECM out of an 88 with a factory T5 to get the full boost in all gears or can I program this one? If I need to find a factory ECM, does anyone know the number so I can verify it is an 88 model.

Oh yeah, first post of many for me!!

Thanks
Scott

Welcome to the board. You don't need a manual ECM for the car to run well. You could just get a manual boost control
valve to get around several limitations of the factory system. See boostvalve.com for a reasonable priced boost valve with reliability and great product support.

If yo want a new ECM, the LA_ (LA2 or LA3)series for 87-77 are the most desirable. However,some of the same limitations apply and a manual boost valve is still a very desirable cure.

Thanks for the input, this is my first turbo car and I haven't got it figured out yet. I am coming from a 93 Mustang pushing 350hp at the wheels so this will be a change. I had an 85 5.0 TBird back in my younger days and absolutely loved it. I ran across this one and I couldn't pass it up!

Pictures please. The G2 gillis valve is a great upgrade.

The boost limit is due to the size of one of the orifices in the turbo fittings... Even with a Gillis valve you won't see more than 12psi using the automatic fittings...

Here are a few pics. I am waitng on it to be shipped to me, hopefully have it next week! I am getting the factory wheels and they will be installed as quickly as possible.

Thanks

Turbo Coupe 50 can you explain in detail what you mean by the automatic fittings? Is this something I need/can change?

Thanks
