hey i have a 1990 ford mustang gt im swaping a 351 w im trying to get a new manual trans i wanna put a four speed in it i dont know whats a strong four speed that can handle like 600 hp and do fine any opinions i would greatly apreciate it

I'm not too sure on the new 4 speed that will hold up. I am positive that there is a 6 speed replacment for the T-5 that can take abuse all day long. Look at www.rsgear.com They will be able to answer your question the best. I use them whenever I have a customer looking for something in the racing stick trans department.

well i was thinking of doing a du processed transmission from a mopar i have one in my cuda running mid 11s and its been doing fine and thats putting aroung 500 hp but heard its a pain to fit in a ford

To tell you the truth, I am not too sure on what other manufacturer's transmission will go in to your vehicle. The best people to ask that question would be the folks at Rockland Standard Gear 1-800-227-1523. www.rsgear.com

Personally, I cannot see how it would all add up
Ford + Dodge =

yea i know but i dont want a six speed dont need all those gears i see 8th mile mustangs use four speed im just gonna have to ask a ford nut

I called Rockland this morning and discused your vehicle with their racing department. They said that there are not many choices when it comes to containing that kind of power. A Jerico would be the best bet according to them, very strong and very expensive. They are available clutchless and clutch assisted, I asked about a super T-10 to which they replied "not strong enough". Hope this helps

u should look at the tko 500 or 600 they will do well with ur setup may have to change a couple of things like a yoke on ur ds n bellhousing but def worth it n they are great 5 speed trans u should def look into them
