what are the advantages of using the manual ecu and manual rear end.
when doing the 5 speed swap

 

with a manual rear end, you'll have the gear ratios designed for the 5speed version which isn't bad, but I chose to stick with the 4.27 auto diff in my 5spd because I wanted a faster accelerating car, at the cost of top speed.

The ecus should work exactly the sme, except you wouldnt have to wire in a PN safety switch with the manual.

 

as do i like the quick acceleration, but dose it affect the gas milage at all, or will it be about the same.

the company i am going to buy the kit from offers two kits
the basic kit which is everything u need to do the swap. 1400 shipped
and the advanced kit which has the ecu dif and gauge cluster. for 1950 shipped

more that likely now i will just go with the auto ecu and and auto dif the only thing that i want out of the kit im buying is the gauge culster.

 

if you really want the stock gearing of a 5sp i have the internals laying around. i blew up my stock 5sp diff so i put in a auto diff.

you dont need the ecu. the gauge cluster is cool but they all eventually go bad so if yours works just stick with that.

good luck with swap
