Yes I searched and could get my answer. I have a 85 se and my buddy has 4 port plates. Can I put the plates on and not change the ecu. I know the difference between the manifolds and have a fix for that. So will the ecu freak out over this?

 

as long as there is input or at least a viable signal from all the sensors, the ECU won't give a damn what engine you run in the car.

 

Actually there was a thread about this a year or three ago.


Use 12A end housings and a Racing Beat 13B 4-port lower for their 2 piece DCOE manifold. That is the key, since they designed their 2 piece DCOE manifold around a GSL-SE lower and make other lowers to suit different engines.

You cannot use the 12A center housing.

 

So youd basically be running a GSL-SE RE-EGI 13b 4 port? As long as all sensors are present as mentioned I think it should work. No love for the aux ports?

Heres a thought... Its been pretty popular lately to run a T2 13b NA. Build your 13b with SE rotor housings, s5 rotating assembly, R5 12A irons with SE center iron, and run the T2 manifolds and ECU/ harness/sensors. It will basically be a high compression NA T2 hybrid. Put a moderate street port on the R5 irons and your looking at about 170 hp with exhaust and intake upgrades.

 

Or you put a S4 intake on the GSL-SE block and also make about 170hp.

Never use a TII intake manifold on anything. It's garbage.

 

Good info guys the sensors will all be there it was the air intake the motor will have will be different and don't know if the edu has a table for the difference. But thanks

 

the edu doesn't have a table for the difference. its a pretty analog table, it gets a load variable from the AFM, which is a mix of the AFM opening and temp, expressed as a voltage. it then takes the load and rpm and a constant, does a calculation, then there is a correction from coolant temp, and then it has an injector time.

so it just takes the sensor inputs, does its calculations, and outputs accordingly. there is no learning, or any kind of failsafe checking.

this is both good and bad, as it doesn't care what engine its on, so it wont freak out, the bad part is that its not very flexible. although i think a 4 port would work just fine

 

Ok that makes sense. Well I'm going to do it and let every one know of what happens. But with this said I could port and it shouldn't matter to a point of how large of port. Hmm thanks for the info.

 

interested in this conversion for my daily, please be sure to let us know the results

 

Maybe if you need some fine tuning you could perhaps put a pot meter on the signal wire from one of the sensors to get a richer og leaner mixture but Maybe someone else know if that would work for you

 

Yes fine tuning would half to be done for sure. Once I get a housing I will start at it and inform every one on the results.I have the end plates and center iron now.

 

You won't be able to use that center housing if you want to keep the fuel injection, unless you fabricate a way to mount the fuel injectors in the intake manifold.
