Early celica IRS conversion

If you can handle looking outside the "family"

It's only the Tasmanians (and Southern Americans) that like to keep it in the family... **runs and hides**

Ouch! If i was a taswegian..

Lucky everyone knows you're kidding

So you going to help me with the s13 front end/sr20det conversion or what? I feel bad copying George, and not 100% on the idea (first I gotta ask the engineer if he is happier with that or a stock 1UZ), and also gotta find decent priced halfcut with suspension still in place... but it's not a silly idea in my opinion. And I think George would be proud!

Nice thead...
I have been looking at doing this to a RA40, coupe.. useing a MA61 rear half chassis,
So far the chassis rails are the same spaceing, eg. '40's rear bar will fit the '61, & vice verser..
wheel tubs are wider on the MA61/RA65, so will fit up inside the RA40's tub's
As the RA28/23 have the same front track & suspension, the 61's rear may fit.
Q: Is the outer part of the '28's rear gaurdes the same width as the 40's..
i measured the out side edge of both the '65 & '40. & yes they are the same width car..
i will be cutting the rear half chassis out of the '61, soon & doing more measurements..

Should take the time now to let everyone know that I was joking and I visit Tassie at least once a year... I would also be proud to live there again, and plan on it! (I lived in Launceston for 6 mnths)

I'm always eager to lend a helping hand... You've already got the IRS end don't you?

[timbosaurus]

Nah, no cradle as yet.

Trying to avoid buying big parts like cradles and halfcuts until I actually have somewhere to put them! And no, straight into the car isn't an option

After driving behind several WRXs and noticing they have a rather similar track to the RA28s I thought how about the Subaru Impreza WRX IRS?

It's well made, strong, would be easily found, and is quite a modern design... (from what I know)

I'm struggling to find all the info, but a '99 WRX has a rear track of 1460mm so the actual width of the setup would be less...

You have it backwards, the track is less than the diff width. So with track of 1460mm and factory wheel offsets of +45-50 ish you have a disc to disc width of 1550mm plus. Thats like Falcon or Commodore width. Will be WAY to wide for an RA28 and probably a bitch/expensive to narrow as well.

I thought the track was outer of left tyre to outer of right tyre???

[WDE_BDY]

Nah, track is to the centreline of the wheels.

Yep, so the Silvia is likely to be wider due to FWD offset wheels. .

wot da helll???(said in an asian accent) since when were silvia's FWD??? they are most definately RWD

You guys are too hardKore for me. I'll just wait till you guys nut it out and manufacture a production line bolt in kit. This stuff confuses my brain. I just lift heavy things.

on that note, if anyone needs a man with a van, I'm your guy

they mean the offset found on the Silvia is the same as found on FWD cars.

George, the sylvias run an offset that is very similar to most fwd cars, which means width from end of axle to end of axle can be greater than a TA22 for instance but have the same track as a TA22.

Go back to lifting heavy things George

j/ks

meh, like I said, I just lift heavy things.
