Wouldn't a 90 318 have been a TB Injection? I know my 88 RC with a 318 is TBI. So there would have been a primative computer just not a primative as an 81-83 IMP.

also in 88 the 318 went to a roller cam, basically a mangnum engine, i think with still only 5 valve cover bolts,,,in 89 the 360 went roller cam,,magnum engine, and i believe still 5 bolt valve covers,, with the high swril heads?? not sure what style rockers

they were both LA heads. the 318 went to 302 heads from ~85-91 and the 360 used 308's from 89-92. both use shaft rockers. magnums with their AMC V8 style pedestal rockers didn't come out until '92 (318) and 93 (360)

I would not wast the time on a 88-91 TBI; the last one I had ran good but MPG? in town empty? 8 MPG. on the road empty? 10.5MPG. in town towing? and/or loaded bed? 8 MPG. Empty 70MPH down the interstate, no T gate, 35 MPH tailwind? a whopping 12MPG. this was an 88 D 100, 2WD shortbed, 318.
the current 88-91 TBI albatross in the garage: 89 RC 360, my son's, recently bought; cannot get the TBI to run correctly to save my life. My solution? It's getting a ThermoQuad! Screw the TBI!

Okay,

So I'm ressurecting this very old thread...

Is there a current, and AFFORDABLE option to install a stock 5.2 / 5.9 in an older vehicle? My preference is for a harness that handles engine parameters only as I wish to back it up with a clutch.

Thnx, Mike in FL

Yes I build one for 250 plus shipping back to your house if you supply the harness or 300$ if I supply the harness. It will only engine, and trans (but only if usuing the older 4 speed overdrive 46rh) unit.

I have done three harnesses and working on 4 & 5 now.

You would need a 143 tooth flywheel that has the notches for the crank sensor. Or a custom 130 tooth flywheel made, if you need the small diameter!

Let me know if I can help!

Justin

Hi Justin,

Thnx for the reply. I will want to do this, probably over the summer. I already have a harness from a '93(?) 5.2, but I seem to recall that I busted one of the injector connectors while I was removing it. Again, my plan is to back it up with a clutch, so I'll be using the AX15 bellhousing, so I have provision for the crank position sensor.

Originally, I planned on putting an AX15 behind a Magnum headed 360, so I already have the 143 flywheel from a 3.9, knowing it would need to be rebalanced. (I already understood the flywheel balance factor on Magnum blocks is different than that of same displacement LA blocks.) I suppose I'll have to get the appropriate 5.2 or 5.9 flywheel to move forward with this planned project.

Thnx much,
Mike in FL

In reference to your question about the 5.2, flywheel, yes you would need a flywheel for a 5.2, the 3.9 does not have the correct number of notches. A 5.9 flywheel is only used with a 5.9 do to being externally balanced.

PM me if you have more questions!

Justin

Justin, my son just picked up a 64 dodge wagon with a poly in it and we got to talking engine swaps and he wants to take the 5.2 engine and od trans I have here from a 93 dakota
and use it in the wagon.

do you still have a harness that would work with this setup.
he said he could get a new MP computer for it.

we wondered what would be needed to use the od trans(just a push button switch)???

we know we would have to do something about the fuel pump and a return line.

can I give you a call sometime and iron out some details thanks Ron...

yeah but I would still go through all the B.S. just to not have a chevy in a mopar

a lot of people just follow the leader and go with whats easy
rather than going with whats right....


Yeah I wish mopar had a harness for the magnum and hemi engines at a reasonable price like the chevys have.

hopefully as more engines show up in junkyards the price will come down on engines and wiring. Ron....

RON there are kits to modify the mopar OD trans to shift in to OD and out automatically, it consists of a few pressure switches to do the in and out of the OD, it depends what OD trans u have a 2 wire plug or 3 wire plug,,any thing more the nthat and its computer controlled,,, ill dig around and see if i still have the web site saved,, if u e mail me and remind me,,, or do a search on it,, it has a full description and pics on the set up,, on the web pretty straight forward don fstfish66@aol.com

Wish I'd seen this a year ago. I have both OBD!/OBD2 manifold/t-bodies, harnesss and pcms from a 93 and 95. the 95 has a hypertech tune. but with the Hughes cam i have in mine i'm not sure the OBD1 pcms will handle it.it's small but on a 112* lsa.
