Default EA82T into EA82 car

Okay, going old school here for a moment.

I have a friend with an 89 GL wagon that has a cooked motor. He came over last night and showed me the receipt for a nice used EA82T.

I know there are a number of things that will need to be swapped in order to do this conversion, but has anyone done it?

The things I can think that will need to be changed out.

swap to turbo ECU - I hope this just plugs in.. though I doubt it.
Adding boost control solonoid - may have to run extra wires to this part
Turbo fuel pump - to make sure the fuel pressure is correct
Crossmember - Does anyone know if the older cars follow the same convention as the newer cars regarding crossmembers? An NA version and a turbo version?
Radiator - Do turbo EA82T's use the coolant header tank like EJ series turbo motors? Will the radiator hoses match up?

Thats all I can think of right now. If anyone has done this swap and can think of anything I have forgotten, please let me know.

J

I hope he didnt buy that "JDM" ea82t from ebay for $750, man what a rip off. Well i dont know about the ecu, but you dont need a factory boost controller. Many of the older turbo cars didnt even have one. They just ran a hose from the turbo to the wastegate. You would be better off getting a manual boost controller. I would try to find an ecu from a turbo car that doesnt have a factory boost controller. I also wouldnt worry about the fuel pump. IIRC the turbo cars only made about 20hp more then the non turbo cars, what a joke. Both the crossmember and the rad are the same so no problems there. Seems like alot of work when you can pick up a complete turbo car for about $500. I hope the orginal engine was MPFI and not TBI. If not i wouldnt even attemp the swap. With an intercooler and a larger turbo(legacy turbo) these cars can be very fast. Have fun

There is a few methods to do this. Sell EA-82T and buy highcompression longblock to put in. Put in EA-82T lowcompression longblock and just eat the power loss. Sell blown EA-82 car and buy a EA-82T car with or w/o a blown motor.

Those are the 3 options avalible to you. converting from a non-turbo to a turbo is not one of them. You need enough parts that its EASIER to fix a very very trashed factory turbo than convert a clean non-turbo.

Can you tell me what parts are needed for this. We have a scrap EA82T car, and a rebuilt EA82T motor.

I imagine that all of the engine sensors, wire harness, ECU, exhaust pipe are all different. That really doesnt sound harder than a normal engine swap.

Please explain your EA82->EA82T is not possible comment.

Ok, you will need to swap the engine X-member. you will need to install the complete engine and aux stuf. then you get to WIRE it which is nifty since there is no separate engine harness, its all integrated into a mess of wires on the body side. the whole exaust is different. keeping the tranny that is in there saves you alot of hassles but it will be slower than hell because the turbo NEEDS the close ratio turbo box. The hydraulic lifters simply don't allow the motor enough of a powerband to do anything else.

Thanks for answering my questions.

We have a Trubo X member
We have both an NA Auto Trans and the Turbo Auto Trans. I am going to try with the NA trans first and see how it is, we can swap to the Turbo if needed

The harness is multiple pieces. We have the engine harness, the Dash harness and the ECU. Basically every bit of wiring from the front seats forward.

We have the complete engine with downpipe. We will get the rest of the exhaust made up at a muffler shop.


As far as it being slow, thats good. The driver is from Japan and has never had a license before. Should be fun car to learn on.

The only reason we are going this is we got both cars, the wrecked Turbo Sedan and a Wagon with a bad head for $500.

The turbo car only has 40k Miles on it.

-yeah that'll be the FUN part. Maybe you could get the wiring diagram and ecu pinouts and make your own connectors so you can mount the ecu under the dash. Otherwise tear both cars apart and run the wiring to the trunk so you can leave all the wires intact.

Default go all the way!!!

i say unless he is really attached to this car. buy a turbo car, i have bought a few for under 1k and drove them home. or if your going to put a bunch of money and time into this thing, then go all the way and drop a EJ20G into it, about the same amount of work. and maybe a few bucks more.

my compleat EA82T to EJ20G converson only cost me around $2500. and it is way better than an EA82T. and i even get better fuel mileage
