IRS into Ta22 celica

[shelldrake]

Hey guys,

I'm looking into the feasibility of grafting an IRS setup into a ta22. Has anyone done one before? Will it limit classes I can run in for racing?

There are several benefits from my point of view:

Pros:
- nicer handling potential
- you can put camber in the rear end!
- disc brake option can happen in the same conversion
- Tail shaft does not have the up/down/left right movements associated with live axel setups.

Cons:
- A significant amount of mucking around...

I'm still investigating things here so input is appreciated. Thanks is advance!

There have been IRS conversions into older celica's before. There was a guy on Toymods (pretty sure) that did a 1uztt and AWD including the IRS from an r32 skyline. I think that was an RA23.

I think there may have been another one that also did an IRS conversion into an RA23 but I can't recall the details on that one. Might have been blue

TA22 being narrow makes it very tricky to get anything to fit, the fitment to the chassis will be relatively easy compared to narrowing an IRS.

hi eddie
i think that the cost would over come the benefits
you can get the handling of a 22 to be quite good
the IRS would be heavier thus putting more weight at the rear = over steer
the celicas were designed for good handling , get the spring / shock combination right and it will out handle any production type IRS an example would be how the rally cars of the era handled and the bathurst entries
you can get 1 0r 2 degrees neg camber into the celica rear end
but that can chew out axle splines after a while

The R32 setup was into a 22, but that was a fully fabricated weapon from head to tail.

For 99.9% of projects i reckon Ian is on the money.

I remember someone on this forum put Corona trailing arm IRS in their Celica. Can't remember if it was 22, 23 or 28. This was a few years ago.

I have an S13 IRS rear end I was going to fit to the 28.. But now having second thoughts.
Maybe too much work for not enough gain.. My problem is I love doing this kinda sh1t which is why I want to do it.

[stidnam]

What about the datsun 180b, 1600 or 200b IRS rear ends? They would probably be narrower than the s13

but that's a ta23, wider chassis and such.

Look at old alfa's for small lightweight IRS.

That was in an RA40, so everything lined up "just" needed the mounting points welding onto the car.

Ian said, well setup live axle can out perform production type IRS... but well setup IRS shits on that!

I agree that it isnt worth it, you would need to spend a lot of money and at the end of it, youd say to your self "why didnt i just buy a MX-5?" They are like TA22's in size but run rings around them in performance. You can pick up the first gen mx5 for 5 or 6k in good nick, just a thought...

If you really want camber, put in a FRONT live axle from some 4wd, you can have camber and toe with those (and 4ws if you really want?). Although most front live axles have the input off center.

Not for a track car it doesn't, which is what this sounds to be?

2 things eddie the island is a hard track to get right on a good day
but start off with 275 lbs springs on the front good shockers bilstein with good bump and rebound go bigger front sway bar say 24mm for the back go to 200lbs same in shockers and the next 1 is get a lsd to stop wheel pick up coming out of corners etc and last go to the 2 day event that piarc runs .get some practise saturday and sprint on the sunday .but me only run the sunday
my 1st timet here was started at 2.16 a lap and got down to a 2.04 at the end of the day back in 97

why would you want people to question your manhood?

get another 22 shell ,cut out all excess weight move the motor back about 1/2 mtr that almost makes the weight 50/50
you can get easy another 80 kilos out ,and thats without using plexiglass
and build a dedicated track car
your 22 is to nice to risk, and it will always be a compromise being streetable as well ,although a quick one ,

If going for a track car width gets irrelevent pretty quick. I've got the complete running gear from a TA63 (3T-GTE/W55/F code IRS) under my little RWD Starlet. Sits 100mm out of the guards each side though....
