ST18X ST20X Interchangeable Parts

Subject: ST18X ST20X Interchangeable Parts Sat Oct 10, 2009 8:26 am

Heres a list of some parts that should be interchangeable on 5th and 6th gen Celica models.

- ST20X rear strut brace should fit the ST18X

- ST20X rear sway bar should fit the ST18X

- ST20X springs should fit ST18X (All 5th gen springs are all interchangeable)

Non Interchangable Parts

- ST20X Coilovers will not fit ST18X

Unconfirmed (50/50)

- ST20X Short Shifter apparently fits the ST18X, but cant confirm (the standard ST205 shifter apparently also fits due to it being smaller than the ST18X shifter)

Will keep updating

YOU DO THIS AT YOUR OWN RISK

Do you know if the flywheel from any of the other Celicas will fit?
If so is there any advantage in lightness at all?
Cheers

Yep, i assume its for your ST182, if you look here:

The ST20X's (with 3SGE's) flywheels will fit the ST18X with 3SGE's.

Lighters good because it takes some load of the engine which makes it more 'rev happy,' as far as i know, the only disadvantage is when you go up a hill, it will 'judder' backwards and fowards.

Its something i cant do because i live is full of hills Sad

You could always get your machined down, just the matter of reliability though

I have always been advised not to get mine machined down, do we know if the 202 flywheels are lighter in anyway?

Cheers guys

Hmm, maybe a little but not sure, will have to find out.

Do you mean if the stock 202 ones are lighter or aftermarket?

Im told that if you machine down your stock one, they dont last long where as an aftermarket one will probably be more reliable.

Cheers,
So putting a stock one in from a different gen will make no difference what so ever, lol.
Cant really justify nearly £300 on a new light weight flywheel is all Smile

nah i dont think so, lol.

I dont blame you, there's a guy over here in NZ who has just added a lightweight flywheel to his ST185 GT4, revs much faster and is still very driveable.

Think it could make a great difference though
