Thought I'd start a build thread since I'm going to be swapping in my 4g63t in a few weeks and I've already started pulling things apart. I'm going to be running a stock 6 bolt 4g63t from a '91 Mitsubishi Eclipse. I already had this engine in my previous truck so most of the major fab work has already been completed.

List of parts needed and/or mods to complete swap that I used to complete swap:
*4g63t and all manifolds/sensors/etc.. from 90-92(preferably) Eclipse/Talon/Laser
*Engine wiring harness, ECU, and MPI Relay from same vehicle
*Shorten/Lengthen engine harness wires as necessary to reach their new position and power/ground the ecu/mpi relay
*KM132 4 or 5 speed manual transmission from late 80's 2.0l Mighty Max/Ram50 with g63b engine
*Motor mounts from 2.0 truck, but fab'd to move engine 1 7/8" forward so CAS and thermostat housing will clear firewall.
*Lengthened driveshaft to go with motor mounts
*Make throttle body flange and weld to front side of intake manifold
*Waterpump from 87-89 g63b 2.0l modified to clear timing components
*Waterpipe from 87-89 g63b modified to accept turbo and throttle body coolant lines
*Custom intake and intercooler piping.
There is a few more I will add as I remember them.


Apart for new seals and gaskets


You need to grind down the ribs on the truck water pump so that the timing belt pulley will clear it

Will update this this week as parts come in

Ok, here's how I modified the stock truck waterpipe that comes off of the water pump. I had to do this due to the turbo and oil filter housing having coolant lines running to them and me running the truck water pump and waterpipe which do not have these fittings.

Spot added right behind pump for coolant line to oil filter housing.

You can see the second big fitting I welded on(came from stock 2.0l DOHC waterpipe). This goes to the turbo. The aluminum tubing behind the turbo is the outlet(or maybe inlet, can't remember which is which) for the coolant that I made.

Another view of cooling lines to and from turbo.

This pic shows the aluminum tubing(3/8") I made to run coolant to the throttle body like it does stock. I figured this was the best way to get coolant there since the throttle body has been moved to front of engine for RWD purposes.

Another shot of the lines to throttle body

Connecting to throttle body.

Hope to put motor in engine bay this weekend and find out all what else I need, should only be some intercooler couplers and few random things

if i could id hit the "Like" button hah

no pics? i got a 4g63 sitting in my garage but it probably wont make it into my d50.

There are a BUNCH of pics there. If they arent working it might be because they are hosted on the other Mighty Max/Ram50 website. Let me know if you cant see them and I'll upload them somewhere else too so this site can see them

My modified motor mounts to move engine 1 7/8"(what I chose to move it) forward

Showing difference of 1.8L cover(parrallel with engine) and 2.0 4g63(pointing towards firewall)

Ready to go in

It's in!

Since I had already done all the wiring troubles on the swap before, I only had to connect these three wires to power my harness/ecu/mpi relay

How she's sitting after the 5-lug swap and new wheels

Great looking truck man my dads got a lil beast started he's dropping a mopar 318 in a 87 Max its gonna be badass

Sounds like it should be pretty sweet dale.

Well I've been getting everything mounted and connected, etc... All I have to do is get my alternator wiring done and finish the exhaust from the end of the cat to the back.
Got the intercooler in its place so I can retain my A/C. Its size is 27x5.5x2.75. It fits right under the a/c lines and the piping goes right around them. Sticks right through the middle of the bumper so should see plenty of fresh cold air.


I will get more finished pics of everything when I put it back together for the final(for now) time.

sounds good is that the motor out of ur other truck?

what size wheels are they and the offset they look really cool on there and they gonna tuck good???

Yea this is the same motor that i had in my single cab. My 2.6 blew head/headgasket so I had to do something quick. I wanted to put this in this truck anyways and it was the best option

Renegade: they are 18x8 +45 offset. They tuck with ease

you got it Goin on mitsu wuz it hard to change the lug pattern

Front was super simple: Totoya pickup 89-95 hubs, new 95-01 Tacoma drilled rotors, all new toyota bearings and seal. Slides right onto the spindle, toyota hubs even use the exact same outer wheel bearing, but the inner wheel bearing is different as it has a bigger o.d., but same size inner diameter. Shim the brake caliper with a thin washer on each mounting bolt, cant remember exact size but not too hard to figure out. I didnt have to do that but I wanted the caliper exactly centered on the rotor, it was a hair off without.
For the rear pull out axles, not too hard just a bunch of stuff to take off to get them off, then take everything off to get them to just the axles themselves. Had to make a plate to use as a puller to separate brake backing plate/bearing from axles. Then send them off to get redrilled(I'd suggest a place like Mosier who specializes in axles and wont take FOREVER to get your stuff done like the guy who did mine did) and when you get them back put it all back together.

sweet I like them wheels better then my cattys

what about the large hub on the rear axles? did they turn those down or did you space them? or was the rim bore large enough?
