My brother drove my 88TC for the first time this weekend and now he wants 2.3T power in his 84 Bronco. I have an 86 TC donar car sitting in mt back yard right now so most of the parts are in my hands.

My questions are about the hardware to put the 2.3 in place of the 2.8 V6. I know I will need a bell housing and clutch to mate to the transmission/transfer case. I will also need engine mounts for the 2.3. Is there anything I have forgotten? Will Ranger parts work? I am pretty sure they will but has anyone done this swap?

Don't DO IT!!!! i wanted to be the first one [Image: wink.gif]

ok this is what i have found

1) use ranger 2.3 mounts

2) use a merkur wiring harness

3) use a ranger Mazda 4 cylinder tranny (already has the hydraulic clutch) or a stonger alternative is an 87-88 TC T5 (hydraulic clutch and good truck ratios) with an Advanced Adapters kit to mate it to the 4x4 (not a straight bolt-in at the moment)

4) You can use the stock fuel tank, just use the stock lines up to the engine compartment - then install an electric low pressure carb pump 1st to pull the fuel from the tank followed by a high pressure inline pump to pressurize fuel for the fuel rail.

Run a return line back to the fuel filler tube.

5) I would look at some of the ranger setups for ideas on front mount intercoolers.

6) You may have difficulty keeping the a/c due to interference with the turbo/manifold -i haven't looked into this because i don't have a/c

7) For exhaust use either the a stock 87-88TC downpipe which is 2 1/2" mandrel bent pipe or a sacramento mustangs 3" short down pipe with a full 3" exhaust system including cat and muffler - there should be PLENTY of room to go all the way over the rear axle

8) I don't know if the stock radiator will be sufficient - but i would flush it, try it, and just have a good back up plan ready.

later

You don't have to use the Mazda transmission, especially as it's probably the weakest of the three types available in Rangers/BII's. Get the bellhousing from a 4cyl. of the same vintage and it will allow you to bolt the engine up to your existing BII transmission without having to modify the clutch set-up. I've been using a Mitsubishi FM145 for about 7 years now behind 2 different turbo 4's without a problem.

As for the radiator the V6 rad. has the inlet and outlet on the wrong sides, the '83-'84 Ranger 4-cyl rad. is about the best one that will bolt in without modifications.

Greg's got the rest of it right.

Thanks guys!! Does anyone else want to weigh in?

sorry for the late reply....

one thing though - Dave R.

my 2.8L V6 has a ToyoKoygo(sp?) tranny behind it - which if i remember correctly from my last clutch job - is an integral bellhousing so i don't know if that will work.

and even if the bellhousing are the same and can be interchanged - are the pilot bushing and input shaft lengths the same ???

all i know is that i wouldn't try hard AT ALL to keep the stock tranny in there - in fact - i am in a hurry to gather up my TC T5 and order an adapter - but that is just me [Image: wink.gif]

The only transmission with an integral bellhousing is the later Mazda unit ('88? and up)

Yes the pilot bushings, input shaft-lengths, diameters and spline counts are the same, between TK's and Mitsubishis.

Overall I agree that eventually swapping up to a T-5 is ideal, but it doesn't have to be done right away. I'd rather put the money into the engine first, then upgrade the tranny later. But, if money isn't a stumbling point, then by all means do both at the same time.

I finally got my adapter completely installed. With the correct length housing you no longer need to modify the crossmember, so I had to undo the modifications I performed. You do have to modify the Jeep protion of the housing to clear the trans mount. I failed to notice that until I had it in the truck, and if I would have been smart I would have taken it back out to make the required cuts. It ended up taking me an hour and a half with a sawsall to get the clearance I needed in the truck, probably would have taken 15 minutes on the bench. I also had to do major cutting/grinding on the t-case shifter, mount and the housing. That's another thing you'll want to check while it's on the bench. Driveshafts now fit perfectly, so make sure you actually measure your trans before ordering the kit. I have only test fit my shift boot(have to remove drivers side of interior for overhaed console rewire) but everything fits nicely using a JY jeep shifter handle. I'll have pics when I get my new camera. The short wheelbase of the Bro II would make it a kick with real power.

turbo4x4 - glad to here it is all panning out with *relative* ease - admit it - it could be worse [Image: wink.gif]


are you going to send the fitment differences to advanced adapters - maybe they could develop a 2.3T accessory kit that includes a few extra adapters to allow a TRUE bolt-in installation???

just a thought.

can't wait to see the ENTIRE finished product - should be a sweet ride...

i don't think my Bronco II will be all that aggressive - any thing more than 200-225hp and the beast will be down right scary with small lift kit and 31" tires if you catch the suspension off guard [Image: biggrin.gif]

good luck all
