88 4cyl engine swap

<< < (6/7) > >>

Soaring:
I think we are arguing about nothing, Steve.   He has an '88.  Ford dropped the 7.5 in the 1986 models, not 85.  But, at any rate, he has a decent 8.8 rearend in there, so just the tranny needs to be replaced along with the brakes.  That is not the same strong T5 you are thinking of.  http://www.moderndriveline.com/Technical_Bits/transmission_spec.htm

rmodel65:
the t5 will last a lot of 5.0 guys run them as cheap replacements true the torque capacity isnt as high. any t5 will grenade.


if he has a 4cylinder car(even a 86-93) it still has a 7.5 rear axle, but it will definitely hold up to a stock v8

I have said it many times that those 80's and early 90's engines were weak assed crap, and I guess if Ford continued to use the 7.5 that just proves it.  The Bronco gave up the 7.5 in 86. 

rmodel65:
the v8 cars gave up the 7.5 that previous 5.0s used

and 5.0s werent very weak :P they were 225hp and 300ftlbs of torque same as an "A" code 289 and they were faster

The more I keep reading about the 7.5 and the 8.8 the more I realize that both you and I are worng, unless this is a completely different 7.5 than Ford used in the mid 60's 6 bangers.    Check this out.

Question #3 - Does my V6 Mustang have a "Trak-Lok" rear end?
No. The 1994-2007 V6 Coupe is delivered with a 7.5" open (non-lock up) differential. The V8 Mustang GTs have an 8.8" Trak-Lok rear in the stock configuration.

Question #4 - How much power will my V6 Mustang Trak-Lok rear end handle?
According to most sources, the 7.5" Trak-Lok will safely handle up to 450Hp. The 8.8" Trak-Lok will handle even more.
