3.38 diff
Hi. I have sorted my diff problem and now have a 3.38 diff.
However is this suitable for a car engined car?
The 3.38 seems to be sort after, but is this because it's ideal for the bike engine cars?
What ratio would you recommend for a car engine powered car with approx 150-170 BHP?

well, theres a simple and a complex way to look at it.
The simple one is, its a lot less likely that a car engine will need a 3.38 diff, so you may as well sell it for £100ish and buy a 20 pound 3.62
diff.
More complex would be to use the gear clac program to work out your speed in each gear (what engine are you using by the way?!) and see if you really
need it

Hi.
I have an 1800 Zetec and Intend to fit throttle bodies and and Mega squirt ecu.
I wish i could buy a diff locally for £20.
I was qouted £50 and £100 for a standard 3.62 from two different yards.

it will depend on the wheel size..
And on your box gearings...
If you fit big wheels.. (read this as circumstance then you need an higer diff ratio to keep the same speed and pulling power of your car...
also you can take it rougly..what do i want? top speed or pulling power?
Tks

15" Wheels.
I would say my most important factor would be comfortable cruising at 80.
