Turbo ECU in N/T

[ShawnsGarage]

I have searched the forums and have read yes and no answers. Im still Not completley Sure if it will work. I have dropped a N/T 4g63 in my 92 GST for temp use untill I rebuild the turbo motor. I need this car to make my 4 mile drive to work for a few weeks. If I use the Turbo ECU and Injectors can I run the car?? I know it will not run 100% but like i said its temp and i need the car. Thanks

so let me get this stright. theres no turbo on this motor? or is there and its just a non turbo motor heres your answer. if theres a turbo on the nt block your fine just run all the turbo stuff and turn the boost all the way down and get on it and you will be fine. if theres not a turbo on the motor your going to have more issues then the ecu because the mass air flow sensors are diffrent. i dont think the car will run correctly at all it will run eaither WAY to rich or WAY to lean.....

No turbo on the motor

 

[talon187]

then your going to have a big issue. i would put the turbo on that motor and all that to make life way eaiser and rebuild the other motor

 

[ShawnsGarage]

Well I would do that But The turbo is locked up so thats out of the question. If I could find someone that had a non turbo ecu that needed a turbo ecu it would work out great because i have 2 of them since i just bought a EPROM ECU before my motor went and i have a stock one that i dont need but i dont know of anyone at the moment.

 

[talon187]

well i have a non turbo ecu i dont need but its more then that the mass air sensors are diffrent and so is the wiring for that the resitor pack is also diffrent

 

[ShawnsGarage]

Well what all has to be done to make the mass and resistor pack work. I have a 92 n/t parts car that i got the motor out of.

Don't worry I did this exact same thing to my car. I'd blown the turbo motor, had already converted everything over and then had to put the nt motor back into it. The car ran fine for getting around town. It was crazy rich all the time and threw a CE light but it was totally driveable. At about 4500rpm it would just stutter from being so rich, but you could drive it below that and I did for about 3 months. I wouldn't say it's the best or fastest way to get around, but it can and will work.

 

[jrohner]

The only reason I could see it being rich is if you are using the nonturbo fuel pressure regulator since it is higher pressure. It won't be putting in a ton of fuel because you will be on a really low fuel map all the time since you aren't flowing much air. It should work ok as long as you are using the stock airflow sensor and stock 450cc injectors. The nonturbo ECU would be a lot more work than it's worth.

If it was me, I'd have the turbo on it and retard the timing and turn down the boost (unplug the BCS, or if you have a MBC remove it)

 

[ShawnsGarage]

Thanks for everyones help. I rarely rev over 3500 rpm anyways so the sputter at 4500 wont bother me. Im gonna see how it works tommorrow and ill post up the results.

 

[talon187]

if you have the non turbo injectors toss them in

 

[ShawnsGarage]

Ill do that to try and keep it from being so rich

Also What Makes more power the 4g63t or 4g63 n/t with turbo? Im Thinking about just getting the turbo and bolting it to the n/t motor.

 

[talon187]

that would be the easiest thing to do i was going to say somthing about that. the nt motor is almost the same but it has oil squiters that blow up under high boost. and the pistions are 9.1 compression no big deal but theres not alot of metal on the top of the piston so under high boost they dont last long but as long as you run 93 octane and stock boost you should be fine

The turbo motor is the one with oil squirters dont know if you worded it wrong. Will the turbo pistons work in the n/t motor?

 

[knochgoon24]

The blocks are nearly the same.
Why not just do all the work on the Turbo engine while it's out? Then just drop it back in.

No don't do that they're different impedance and it will go crazy lean. For god's sake, just trust me that my method is the safest method. I've been there, done that, and ran the motor like that for probably 4 months.

Kyle -

Did you have all the sensors hooked up? It shouldn't have thrown a CEL... Id jsut run the n/t with all the turbo stuff hooked up except the turbo, and hack the shit out of a MAF that way it would have a chance at not running soo rich.

 

[mavisky]

I can't remember if I did or not. You've got to remember this was all like 7 years ago now.

 

[talon187]

just buy a 13b turbo from somone for like $50 and toss it on the nt motor and run it on stock boost no problems as long as you run 93 simplest and easiest way to do it. yes you could put the turbo pistions and rods in the nt motor the turbo and nt mtors are exactly the same all for the diffrence is the oil squiters and the pistions. the heads are the same blocks are the same. i thought the oil suqierts were in the nt motor....i dont remeber them when i took my turbo apart...

 

[mavisky]

FWIW I have turbo pistons and rods in an nt block on an nt crank in my car right now. But you'll have to transfer over the water pump cross pipe, oil filter housing, and thermostat housing along with the proper manifolds in order to hook the turbo up to the nt block. If it's only going to be temporary while you rebuild the turbo block I say just drop the nt in and drive it as it'll save you a ton of gaskets that'd just be going into your turbo block anyways.
