im wondering if the stock 1st gen solid rear exle is strong enough for a daily driven t2 swapped fb. im looking to buy an fb since im sick of of all the problems my fc is having. also, would a t2 rear end swap in with relative ease?

also about the stock fb rear end, i will run stock rims with the same tire siez direct freak runs. i like the way it comes out soo far but still in the body. also i will be runing anywhere from 300 to 400 rwhp daily drive with the normal showing off type of abuse.

 

A first gen rear axle won't hold up long at 400 rwhp. No way with "normal showing off type of abuse". With stock T-2 hp it would do just fine.

 

Stock should handle up to 300 hp after that you're looking Ford 8.8.

 

Unless you have some serious fabrication skills and experience, the TII rear end swap is not going to happen. A Ford solid axle rear end is a better choice.

 

hm...
300 whp could be doo able. what about the t2 tranny? will the mazda trix modified driveshaft fit?

 

if the mazdatrix drive shaft is made for the t2 trany in a first gen then yes, but if not a custom driveshaft will have to be made.

 

When you decide what you want for a rear end, and get it installed, take it to your local driveshaft shop and have one made up. If you have the TII and FB driveshaft, they can use the yoke and flange to make a new one up for your application. Probably cheaper too. If you go with the Ford rear end, any good driveline shop will have the flanges on hand, the TII yoke you may need to provide.

 

Having a driveline made to your specs is a simple job for a driveline shop.The TII tranny should be considered a mandetory step for your projected goal.Its an easy swap compared to the rest of the job.
The driveline/tranny is the least of your worries if your looking to make 300-400 WHEEL hp.That works out to a pretty potent engine,so Id start looking at Ford 8.8" rearends, right off the bat.
My stock SE rearend has held up just fine for years behind my TII swap,but I dont "show-off" abuse it hardly ever, and I "only" make about 300 CRANK hp.Perfect for a reliable,balanced daily driver.
350-450 CRANK hp is gonna be a serious handful,so be ready to adress suspension,brakes,chassis rigidity and safety issues.These are very serious issues that are not as big a deal when doing a similar buildup on more contemporary cars like the FD, or even an FC.The FB/SA chassis is lots more flexy and sparten in stock form than its offspring.

 

hm... ok. ill see what i have to deal with. i dont know. i hsave a complete t2 driveline and my fc is takin a poopey doopie on me cus its making a stupid noise that i cant figure out. plus its got a horrid dent on the side. so im looking for a better chasis. i didnt find any info on a t2 rear end swap ( im saying it many tims so searches will find this ) and i was just considering an fb a an alternative.

 

The FC rearend,while stronger and more modern,isnt neccesarily better than the FB's simple solid axle setup.

The FB's axle design isnt perfect either,but its WAY easier to MAKE it right, than it is to swap in a TII IRS setup.The entire back half of the car would have to be re-thought in order adress the IRS's different pickup points and configuration.In a nutshell,its a very long,technical job that few have succesfully completed.

The Ford 8.8" axle is relatively easy to swap in.Youll also have others that did the swap before you,to pose questions to.Less likely to mess up and butcher your car's unibody like one might, when attempting a one-off,full IRS setup.
Once the FB suspension quirks are sorted out, the Ford axle will gain you brute strength,better lug pattern choices and bigger brakes.In the end,youll be just as well off as a TII rearend swap,but with less cost,time and hassels.
