Alright since going through say 2.5 diffs, reused a set of gears that only had a spun pinion bearing on the with the lsd from the second diff. Said its time to invest in a 8.8 ford rearend (grannys), TII brakes, ball joints, strut monuts, polyurethane bushings throughout for now. Re-speed rack and pinion down the road, thinking about going from a 720 to 1000 primary's, meth injection, more boost and 10.5s?????? should be starting this weekend ripping apart the car and snapping some shots!

 

If the car is going to be used for anything besides driving in a straight line, I would recommend a different rear end (see my sig).

 

so just to be 100% sure that part # is mz072-ha.....

 

the ring and pinion cant handle more the 375hp.

 

maybe some one will post that's made more then 375 on stock r&p....or you can get the gears hardened...

 

It can "handle" it. Maybe not doing hard launches with drag tires, but that is not my thing.

 

IMO there is no point of power if you can't use it in fear of breaking the car. Overbuild it, and have the peace of mind.

Here is a picture of my setup


I also went with a wilwood 4 pot big brake kit in the rear, which is a pretty nice setup. My biggest issue is I am still trying to find a way to try and retain the stock e-brake handle with a new cable in order to make it work. But your lucky and very close to forcefed, they did a great job on that 20b fb with the 8.8.

 

very interesting with the exhaust, is that for the coilovers? Im using stock fc items so it should fit altogether

 

Currently I don't have coilovers in the rear, but I do have the adjustable spring height option from grannysspeedshop, the spings they supplied me were way too long though. I need to get some shorter ones at some point, I ended up trimming them down for the time being.

The exhaust was routed under the rear axle for simplicity (forcefed did the welding for me), lack of room, fewer bends etc.

Feel free to ask me any other questions about the 8.8" from grannys if you would like. It was a pretty straight forward install. One of my only complaints is that I am using their heim links and find that when loading and unloading the drivetrain I get some noise from the links twisting under the load.

 

I opted for the watts sleeves most cause of money, i was looking at my exhaust and i should have clearance

 

There is clearance, if you look at my picture above the exhaust would have to take a tighter bend above the rear axle and would sit alot tighter against the side of the gas tank and between the right rear spring. I wanted my exhaust under the rear end for simplicity, less bends and we used a vband before that piece if I ever decide to change it. The picture is kind of decieving as well, the exhaust is not the lowest component under the car either. The rear end brace sits quite low.

 

Finally I started to tear the out SE rear, went better then i thought. couple pictures taken aswell!

Progress!!! Got the bushing in and the rear end loosely bolted in!!!

interested in the results,as i'm looking to using a 8.8 also for my build
can you pm the info regarding some of the costs & details

 

That depends on your definition of "handle". My car is used for road racing so it needs to be able to "handle" the turns and be able to put power down while going around corners. I test drove a car equiped with a Ford 8.8 when I was trying to decide what to put in mine, and it could not "handle" the power while turning.

I'll let you know if I ever break my ring and pinion. So far so good. I think the OS Giken is currently set up with enough slip to minimize excessive drive-train shock. If necessary, I can remove a few plates with my new power level.

 

Ive broken two ring and pinions. was the car equipped with the sway bar? "Handle" im talking about it wont break. with the extra size on the diff im expecting the car to have more tractionbut with the posi instead of a limited slip i can see the tail giving out

 

Did you grab the "Level 2" 8.8 Package from Grannys? What gear ratio did you go with?

 

ya level 2 with 9inch ends. gear is 3.90

i was mistaken its not a posi but a TracLoc clutch style limited slip
