have turbo for the motor.
what plumbing to use for it (downpipe and intercooler pipes) and what parts to use for the turbo. have the kit already, just need some pointers. the motor is carburated. or is it even possible to turbo that engine? will a fuel injection conversion be necessary?
thnx

That engine was sold in a turbocharged version in the Mirage. It was fuel injected with a very simple system. I would recommend getting all that you can to swap into your project.

I'll chime in as I have just aquired most everything that is needed for the swap on a belt driven g32b rwd.

The manifolds bolt on of course. The turbo colt 4g32t uses the same throtttle body setup as a starion so you can just grab one off a 2.6turbo stairon.

Turbo wise, you might as well not bother getting the turbo, it wont work unless you want the intake pointing into the firewall. Since the flance is ta triangle you cant turn the turbo around.

My plan for the turbo is easy, just make a adapter for a td04 ot td05 turbo or whatever I find. Preferably something mitsu.

So in chaning pipes the crossover really isnt needed either.

You will need the oil pan or modify an exhisting one and the oil filter housing as it has the place for a oil feed line on it

Luckily wiring on these things is basically the exact same as a starion.

In fact. I talked to a guy running a eclipse 4g37 1.8l head on his fwd turbo colt with a 86 starion ecu and injectors on a 4g32turbo engine. The catch was he was running a 4g32t MAF. I guess it works. Seems like it wouldnt but who knows. I have a 86 colt fsm withthe ecu pinout and it looks like the pinout for a colt ecu and a starion ecu are the exact same. Ignitore is the same as the tps and idle stuff.

Another piece you will need is the turbo distributor.

Oil feed you can take off the car or make your own.

The water feed line off the colt runs off the side pipe that runs around the side of the engine. You dont really need this as you can figure out another place to run the water feed from. or just braze in your own hard line in a omre convenient location. Return line you will need to use your own. I think one off a stairon may work, or just plumb it in on the radiator hose somewhere.

Talking to some turbo colt guys most of the starion modding is the same as the colt, like using a 1g maf etc...

boost wise I dont know. I assume the stock pistons have cast rings so they wont take a whole lot. I am willing to bet the turbo colts had chrome and moly rings like the starion and possibly different pistons with larger ring lands.

The original NA G32 pistons are a T slot oil wiper. They are weak.

As for the rods and crankshaft, They are very similar to a 4G63. Same bearings, crank itself is a bit more stout in areas.
The rods are a bit longer than a G63 but have smaller piston pins. Otherwise are equal in strength.

If you change the pistons out and have good pins , put the boost to it just like a G63. But with stock pistons I would stay conservative.

Back in the mid 70s, Accel corporation made a turbo kits for the G32 in the Colts. At the time they claimed about 300HP. Pretty much unheard of power in those days.
I got to drive their test car, The car pulled third gear as well or harder than my car pulled 1st! The power was impressive. The car used a draw through 4 barrel that was up by the right headlights. Driveability was a bit less than we would call horrible these days.

Only the turbo moutning and cross over pipe or intercooler piping if you run a ic. Frankly most of the hard work is done like the fuel injection portion. But, yeah it isnt a direct bolt on. I suppose you could make it one but I;d have on iudea where you would run your mas abnd intake pipe., Through a hole into the passenger side floor lol

Yes things were rather simple back then, or would crude be more appropriate.
I somewhere have pics on slide film of the car. If I recall the turbo was a rather large Air Research unit.
Anything built up today will be a much more refined system with far better driveability.

The stock turbo housing could be swung around with a simple adapter plate. I will be doing this with some 3000GT turbos which are similar in mounting.
I intend to use a ⅜ steel plate with the holes drilled as needed.

Those are the 4G61, they are the little brother on the G63 that is such a great engine to work with. Defiantly more work to get it in and the sky is the limit for power.
If you did swap in a G61 the benefit is the torque will remain a bit lower so you do not need to change out the rest of the driveline. The part to consider is the torque from the engines can climb to the high side of 400 Lbs real easy. This gets to the limits of the original driveline pretty quick. If you do not go crazy with the boost then all is good. Put the boost into the 20+ range and you better have swapped in some stronger parts behind the engine.

You might have been thinking of the turbo cars from 84 to 88, they were the G32B turbo. They are where to get the parts for your engine.
In 89 they went to the twincam 4G61 engine. I thought of these as the hatchback but all the Mirages in the 80s fit that description, my error.

That had the 4G61, I have one here with a G63 with a 20G turbo. With no LSD it just baked the right front tire at any speed. The car had rusty rockers so it is retired and the engine has moved of to a new chassis.
