'93 Van with 4G64, rebuild + turbo or 4G63T?

[JonnyRochester]

I am about to start work on a customers '93 Mitsubishi Van, which I'm told has a 2.4L 4G64 16V single cam motor. This customer wants some turbo fun I think. Please help me out and let me know what combinations will work, what gearbox and clutch etc... to get close to 200rwkw I guess.

options:
1. Rebuild the 2.4L with custom forged pistons of some sort, compression ratio of about 9.4:1 I guess. Custom exhaust manifold with a Garret T3 turbo, or GT2871R or something. Retain standard motor and intake and gearbox. Use a aftermarket computer etc... Maybe bigger injectors and fuel pump.

2. Fit a 4G63T galant/Evo motor. Will it fit the van gearbox?

3. Fit a Toyota 1JZ-GTE or something else...

Im probably not the best person to be offering advice on this matter, but what the hec. :lol:

Option 2.

Get a 4G63T, and rebuild it.. You can disect the guys 4G64 and use some of the parts to make a 4G63 2.3L stroker.. like the crank for example.

If its RWD though, you'd probably be able to make that sort of power on a stock 1G 4G63T motor.... :?

De-stroke the 2.4 to 2.1 and rev the fucker to 10,000rpm 8)

Thanks for your help. Keep the comments coming, I am actualy going to do this project very soon.

I have previously rebuilt a Galant VR4 (same as early Evo I think) with big turbo and MicroTech. Got about 195kw etc...

I guess we have the option of either getting a Evo motor, or turboing the existing 4G64 which I have not seen yet. Or building a hybred which would mean getting a EVO motor anyway.

Most people may just do the whole EVO motor swap. Then the question is what year Evo motor do you use, for a '93 van to be legal. Will all of them fit the van gearbox and flywheel? I have seen people talk about narrow and wide block, and 6 or 7 bolt crank. I am not sure which is which yet.

Would it be silly to just rebuild the 4G64 and turbo it? Would aftermarket Evo exhaust manifold fit the 4G64?

 

[DOUGMO]

all 4g64s are wide block

4g63 come in wide and narrow

 

[EVOCPE]

EVO 4G63T motors have 7 bolt crank

Galant VR4 4G63BT motors have 6 bolt crank

 

[GVR40]

i think for it to be legal the motor can't be older than the car

If you put all the correct emisions systems and have it engineered it would be legal?

[drum roll...] Where's that? can you draw me a map of it please? :lol:

Yep, 63 head on the 64 block... that way it keeps the stock engine number :lol:

I didnt have any such problems :lol:

i was going to do a starion turbo conversion into my van about 3 years ago.. got the motor built and all only to find that the stock gearbox does not bolt onto the starion block cos the starion block is the 330mm block instead of the 310mm block i needed.

I suggest that you measure the bellhousing on the gearbox.. see if it is cable or hydraulic and go from there. If it is 330mm i suggest you try and find a starion gearbox for it, should all bolt up.. however the selectors on the box might be in a different location not sure.. your main problem i think with trying to achieve 200rwkw is that the drivetrain was never intended to make that much power.. so you have afew options.. of whether you wanna run the stock box.. blow em up.. replacem with stock ones.. or u can go get yourself a bell housing adaptor plate made up and run something like a 7MGTE box or a skyline gearbox.. those boxes should hold that power comfortably.

So if it was me i would do it in this order:

1. Check the van to see if it runs the hydraulic or cable clutch.. if its cable.. definately convert it to hydraulic so you can run better clutches!

2. Measure the bell housing.. see if its 310mm or 330mm

3. Check the fuel pump setups.. i assume with the 4G64 that its EFI (some 4G63 SOHC vans are still carbied, up to 1998 i think)

4. (personally) I would go the 63T block.. so many parts available cant really go wrong.

5. Sort out your clutch/box.

Thanks alot JStyle, very helpful.

Which part of the belhousing or block do I have to measure? I still havn't seen the customers vehicle but we will start any day now.

But... I have been told we maybe doing the same to the customers Triton ute. We have a EVO 3 motor lined up.

The Triton is a '93 I am told, with 4G54 2.6L carby motor. Can we put a Evo 3 motor in the Triton? Will engine mounts and gearbox bolt up to this also?

Basicaly I need to get my head around the wide block/narrow block thing to find the right gearbox and flywheel, then I can do everything from there. Thanks.

 

[DOUGMO]

you have to measure dowel to dowel on the rear of the block,

centre of dowl to centre of dowel

JR, are you a apprentice mechanic.

 

[JonnyRochester]

I am the head mechanic, but it makes no difference. We have to do the conversion all the same. I work on imports all day but all my conversion knowledge is about Toyotas. I'm greatful for any help here, thanks.
