What's a ma45 lsd diff out of?

[terrytuffguy]

I brought a live rear diff that has been modified to fit a kp60 Starlet, apparently it's a ma45 LSD celica diff. But what model Celica, and what engine would it be running to require a LSD? It's quite a large diff, it may be simular to the one the 10second DX corolla is running, if so then it should be strong enough for what I need it for.

cheers

an MA45 Celica, very similar to a TA45 but with the M-series engine

[Logan]

f series, gernearlly, and most likely however some ma45 have a t series.

[terrytuffguy]

letters dont mean much to me people What year celica? And what size engine? Is it a celica/supra??

maybe you should do some reasearch to familarise yourself with the cars you are grabbing bits off, so yo canm asked slightly informed questions.

they're a late 70's to 81 Celica/supra with a 2.8 straight 6

Oh ok cheers, Are the next model celica/supras IRS? The 10s DX is running a MA70 diff in a celica housing from what I've read, is that a later model diff head in a live rear end?

[fangsport]

possibly the same housing as the IRS heads can be fitted to the earlier live axles of the same series

[terrytuffguy]

hope so! I'm worried about blowing the diff and not being able to find another one. It cost the guy $650 to modifiy my live rear end to fit into a starlet, and apparently $500 to buy the whole live diff from a wrecker.

[fangsport]

the heads are still available ex celica /supras. with a starlet being as light as it is, a fair amount of grip wold be needed to blow one(or a few dumbass roll-backs)

[terrytuffguy]

If I can run a ma70 diff head like the Speedtech DX then it would be definitly a no worries option. BUT my ma45 diff is quite large, and I'm only running a light clutch at present. Only gonna be worried when I run semi slicks and start doing high rev launches to reduce turbo lag. It is likley to have some wear due to being an old diff.

[fangsport]

it might not be a silly idea to get the head cleaned and re-lashed and run some decent limited slip oil in it.

a small clutch might not be a bad thing, it is then the weak link which is better to blow (and easier to obtain) than the diff , box etc.

[terrytuffguy]

Its running redline diff oil. But yea theres FA weight in the ass of a starlet, even with semi slicks I still think it will get some wheelspin which will dampen the shock. I'm running a W58, no worries about blowing that! It's running a 9inch clutch with a standard supercharged pressure plate, I may need to double diaphram it just to hold the 300+ hp I expect to get.

[terrytuffguy]

Also do the dx corolla's like the Speedtech one have live rear ends? He may of converted it to a IRS setup.

[wde_bdy]

It is most likely an F code diff with 7.5 inch crownwheel, the centre from the IRS *A6* Celica/Supra's can be fitted if they have the F code (some are T series) but you need the right bearings. The MA70 is a G code with an 8 inch crownwheel with later ones changing to A or B code (apparently they are very similar, maybe interchangable). This the same as most Hilux/Hiace diffs.
Do a quick search on the net, there are plenty of listing of what the different diff codes are, as well as the codes for different cars/body styles etc.

Starlet project in the build.....look out for a crazy little orange starley.

what motor u plannin on droppn in ure kp to produce 300+hp? Sounds wicked dude

[terrytuffguy]

I wont reveal that much But I can say that it will be an expensive 4ag setup running huge amounts of boost.

DX runs a solid rear end.

u keep talking about "matt_dunn"s DX. why dont u just pm hm?

umm, i don't think so. the back Speedtech DX is in the 10s and is from Wellington. Matt would like to be 10s in his yellow one from Timaru.
