Re: Eagle engine swap?

["Jim Blair" <carnuck@xxxxxxxxxxx>]

A: Wrangler flexplate "looks" just like the Eagle one with a CPS ring added. 
I think the offset is slightly different, so it would need the matching TJ 
starter. (there may be a slight casting difference in the 999 case to allow 
for the different starter)
   The Renix header with front pipe bolted right into my '84 J10 (I still 
needed a custom trans mount, but I'll see how the AW4 with HO JGC 4.0L trans 
mount works very soon.)

" The EFI is the way to go. The 4.0L will bolt
" right to your 998 and the computer will have no problem with the trans.
" You will either have to modify your bell housing for the CPS (crankshaft
" position sensor) and the AW4 flexplate (required for the stock CPS) for
" the TF torque converter

a wrangler flexplate should be right from the get-go, as they used tf
autos all through the '90s.

another thought: if you get a wrangler 4.0/tranny pkg, compare the
tranny output with yours.  there shouldn't be any difference but
relevant parts will swap if there is.

" With
" the Eagle you need the 87-90 intake (Renix computer, has an EGR valve,
" but can be modified to use later electronics) or a 99+ intake from a
" Grand Cherokee. Otherwise you will have a clearance issue with the power
" brake booster.

another point - the exhaust.  the '87-'90 'renix' header fits eagles
without clearance issues, but the '91-8 'ho' one needs some bending.
for the '99-up iron split manifolds, just have your muffler shop fab a
y-pipe to suit.

" I'd run the late 2V intake with a 2V to 4V adapter with a Holley 390 or
" 450 cfm 4V carb. That makes a much nicer setup than the old BBD 2V
" carb! A lot of Jeepers do just that, works great for low to mid speed
" torque, not as good as a real 4V intake for higher speeds. You could
" also get the BBD off a late model 318 from a rear drive 80s Dodge
" Diplomat/Chrysler New Yorker. Use the base plate and top off the AMC
" BBD. The 318 BBD has 1/16" larger bores in the center section, the same
" size base and top. Base and top are slightly different between the AMC
" and Chryco versions, that's why the switch.

later 318s and 225s switched from the bbd to a holley 2280.  it swaps
right into place - on them.  it would take some linkage work - and i
think choke work - to slip onto an amc.

btw i've heard the 318 bbd rated ~350cfm.
