So 250 hp in an MGB has been fun but too many times a quick hit on the gas just spins one tire. My options are drive slower, get a narrowed GM or Ford rear with limited slip or put a quaife in the stock diff. Found a new quaife deal, but not sure what to expect for an install charge. What is a reasonable number to expect?
Toyman was talking about how semi-recently he went around to find a shop to rebuild a 3rd member for a jeep and no one would take it so he had to do the work himself
You might want to call around and even see if you can take it somewhere
In reply to porschenut :
I hope you have better shops than I do.
We call 5 shops to replace a set of pinion bearings on a Dana 30. Zero takers. Even the local race shop stated they don't do gear setups.
The one place that said they did diff setups wouldn't work on anything aftermarket. Since we had aftermarket gears and an LSD, no dice.
I ended up doing it myself.
Edit: It's not hard to do. I just didn't want to screw with it because of the heat.
In SE PA? I'd probably call Ragtops & Roadsters. They won't be cheap, but I'm pretty sure they can do the job or know someone who can.
Edit: Just talked to one of their techs. They can do it, but they're booked into November so there's that to consider.
Is that the banjo rearend housing? I've only played with a few MGB parts on an Elva Courier. If it is, it is an easy job to do on the bench. Pick up a cheap dial indicator and some GM gear marking compound. You wont need to mess with the pinion if you aren't changing ratios.
Not doing it, just not the type of thing I will attempt. I want a shop that knows BL axles and has put one in before. But if it gets too pricey a custom rear end is the next option. Right now I am at about 2500, but a US axle with posi can't be much more. Maybe.
I have a Quaife in the MGA race car ad like it a lot. Installation depends on whether you have the older banjo axle or the later style axle. If banjo, just take the 3rd member out and give it to a gear shop with the Quaife and they'll give it back installed and adjusted for a pretty modest sum. The Salisbury axle would need to come out and be sent to the shop to build the diff into the cars, so would cost more.
I run the early axle style in my Jamaican/MGA with less power than you have (c. 200) and have no issue with spinning wheels but I'm running 6" Dayton Cobra wires with some fairly sticky 215x60-15 tires on them.
