No but I think what he is saying is that the turbo pcm can at least read the boost levels and react to them as appropriate even if it is being controlled elsewhere(ie eboost). The N/A pcm doesn't have the inputs to read boost and therefor cant react to compensate.

No idea if this is right. Just what I took from what ninka has said. Feel free to correct me.

Ah okay.

Thanks for that.

I was just curious as Im fitting an NA motor into an EA with a turbo conversion. Im having trouble finding a turbo ECU and was going to get an autronic. The NA ECU may have been a good option if it worked well with edit.

You pretty much got it

The 3rd plug on the PCM (which is not used on a N/A) hooks into a boost sensor, which in turn allows the PCM to select which tables to use for fuel and ignition, and controls the boost solenoid.

With an e-boost, the control of the solenoid is taken over, but the boost sensor is still hooked into the PCM, allowing it to see the boost level.

You will need to take all or nothing of the engine control to make this work properly.

Frankly, if you are modifying an EA, why didnt you get a Turbo engine in the first place? You will end up having to spend more money on the conversion (if doing it properly) than the complete Turbo engine would cost you.

Define properly?

I didnt want a turbo engine to begin with as I wasnt 100% sure it would fit and an NA motor was 1/5th of the price at the time. I had plans to upgrade the internals anyway and I already had a GT3540, tial wastegate and EMS 8860 lying around so didnt really see the need to begin with a turbo motor. I have since changed to a GT51R with a custom split pulse exhaust manifold to suit and decided to buy an autronic SM4 that will run the dual VCT. Im waiting on Ray Hall to release a new version of the SM4 this month that will work with the standard cam sensors.

OK - Properly defined

If you start out with a N/A engine, as a minimum you would need the following to do it properly:

Inconel exhaust valves 12 pcs @ $90 ea

Stronger Valve Springs

Turbo pistons

F6 Rods

Turbo Exhaust Manifold

Turbo

Turbo PCM + Boost Sensor and all other Turbo sensors

Engine Loom

Now you can probably pick up a N/A engine for around a grand, and a complete Turbo or F6 engine will probably cost you 6-8 grand, but if you have to make the modifications listed above, the difference quickly disappears.

That was my point.

If you have the enthusiasm and time to do this cheaper, then good luck to you, I'm just trying to point out the pitfalls.

I fitted a ZF 6 speed, even though people said it couldn't be done, but I am now driving the car every day

It did cost a packet though, as there are always surprises

If I was aiming for sub 380rwkw then yes I would have bought a typhoon motor to begin with. The entire package would have been good enough but I want more than what the standard typhoon motor can give me.

Apart from the exhaust valves and ECU (which Im yet to see transplanted into an earlier car) I would change everything on your list if I bought a turbo/typhoon motor. IMO there isnt a whole lot of point in spending $5K extra for parts that arent up to the task anyway.

Fair enough

And I agree with the ECU comments as well, would not be easy to do due to the CAN network talking to the BEM, ARS ICC etc.

It's funny how many people told me that it could be done, but when I asked them to do it for me it wasn't possible.

I came to the decision that as the car is only a toy to be driven to and from the track then I wouldnt need the factory driveability of a factory ECU + edit setup.

If I owned a BA/BF then it would be more important.

that's what I was trying tp say earlier

Apparently a NA BF xr6 was taken to a sydney tuner recently, atomic bottom end fitted, NA head, T04z ect... 400plus and owes hime like 45 inc new car price... seems like smart thinking to me

Dan, cant wait to see it going mate... you've taken all the right steps to get to where you want it
