My car is Under 2L sports sedan.
Originally built and raced by Gerald Mammi in Melbourne.
Its a full chassis car weighing 620KG I'm told.....I haven't weighed it yet.
Its running A15 with celica 5 speed.

I can scan the sheet that came with the car and e-mail if if you'd like to know as much about it as I do. I have some old pics of it too.

My intentions with it are hillclimbs/sprints to start with and when the cars sorted I hope to do some competitive racing. We don't really have a class for the car here so I'll be lumped in with the street cars but thats not all bad.

If its developing reasonable power then the H145 is probably not going to take it!- specially if they're welded up.
I suspect you may actually have a H165 in there. And unless the events your doing have some big long straights you probably want something rather low i.e. 4.4, 4.6 or 4.9 even.
Suggest you check it some how - get some who knows the difference to hve a look.

I'll try to have a crawl around it over the weekend and do some measuring.

I also have the centre with the broken axle I can measure.

According to errol I'm only looking at 140hp in a 620kg car (without fat driver)

Cool.

My H145 let go with an A12 engine that had 120 hp at the wheels (maybe 140 at fly wheel if lucky) and not a lot of torque, in a car the weighs in at 605kgs without fat driver.

Sounds like you'll only need my LSD centres - the LSD units will replace the parts that have been welded in yours, and whilst there you'd take the piece of axle out.
This would also help with the freight charges.

PM me if you want to talk price e.t.c.

Careful neil cause I heard they also used the 1200 ute diff on those cars.
