Things that DONT interchange

[TooF]

Just wanting to start up a listing of bits particulary aftermarket items that are listed for a specific application but are either wrong, dont fit, dont work etc etc.

kinda the exact opposite of the TIO thread

to get the ball rolling.

ACL gasket kits listed for big port 4agze's (PN: GR901MT)

dosent fit a gze properly. the inlet manifold gaskets are for the small port engine, additionally it has gaskets for the bigport (i think) EGR. and a few bits and pieces that arnt much use.


so and buy the 4AGE one which is essentially the same and contains all the bits you'll need anyway and its about $60 trade cheaper.

Cool idea dude. Just to keep with the 4age theme...

1. TPS sensors from small/bigports are not interchangeable. You can switch the whole throttle over though.
2. Small/bigport manifold dont interchange without an adaptor plate. Same goes for 20v ITB.
3. Water pump pulleys and crank pulleys have different offsets so you cant use a FWD water pulley with a RWD crank pulley. The actual water pump has a different offset as well.

I'll put down a few more when i remember them.

Uh, remember to check the facts before you post them. You can infact use an RWD pump with a FWD engine, they have the same offset.
Im pretty damn sure the pulleys are the same as well.

XA2X celica steering box and idler arm dont have the same bolt pattern as the RA40 item. All XA2X items interchange though. XA2X seats dont interchange with later model seats, so you cant easily bolt in later model seats. XA2X T series Diff axles dont interchange with pretty much anything else, they are about the shortest diff that toyota made. As mentioned by somebody else(cant remember who) the TA22 bonnet hinges dont interchange with TA23/RA23/RA28 hinges. Also mentioned by another person, early TA22 rear bumpers dont have the same bolt pattern as later TA22 rear bumpers and XA23 rear bumpers.

Thats all i can think of for the moment of items that seem to fit but dont.

Cheers, Owen

I did. I just re-checked it then. Definately different offsets. I have a waterpump off a smallport ae92 and an ae86 4age rwd pump and they're different. The fwd water pulley is also much shallower than the rwd one.

edit: gimmie a few minutes and i'll find my camera

Considering that we just put a 4AGE RWD pump on a Blacktop 20v on Thursday, i can completely assure you that they fit and that the belt aligns properly.

[Big T]

Hmm perhaps it's only for 16v engines?

The pump on the engine is the rwd one.




The one on the left is the fwd one.

Hi,

While RA28 and RA25 rear bumpers are interchangeable, the front bumpers are not. The RA25 front bumper is unique to that car, except of course the TA27.

The rear light assembly of the RA25 is not easily interchangeable with the RA28. If you want to put the 25 rear light assembly onto the 28 you will need to modify the mouting holes 'cos they don't line up, plus some trimming work. Also you'll need to fix the centre section 'cos you don't need it to pull down to put feul into your RA28 ('cos the filler is on the C pillar - not the rear centres as in the 25).

While it is possible to put a 28 rear light assembly onto a 25, you'll be faced with similar problems and you will need to make the centre flap pull down so you can fill the car.

The bonnet of the 25 is not interchangeable with the 23/28 or the export TA22. However, it will interchange with the long nose JDM TA22.

The steering, suspension parts etc on the 25 are interchangeabe with the TA22 'cos the 25 uses the same chassis and running gear as the TA22. Dont try to use 23/28 parts as they are different.

The above may not interest most of you - unless you own a 25 - but I put it here to enlighten you and offer you some insight of the confusion and difficulty a 25 owner has when procurring parts.

xA6x celica heater cores do not fit the xA6x supras - heater hose in/out point the wrong ways and dont even make it through the firewall

Um, the 2ZZ-GE with 6-speed box does not bolt in my AE86.

Also, I can confirm the FWD and RWD 4A waterpumps have a different spacing (in a few ways), and the matching waterpump pulley needs to be used. RWD pump needs the RWD 4A-GE pulley for the belt to line up.

[Dimitri]

all 4a pumps are compatible with each other. you just need to use the right pulley with the right pump.

the differance is the rwd pumps (4ag and 4ac) are longer, they have an aditional bearing to support the load of the engine fan. to compensate for this, the rwd pulley has a deeper offset, to line up with the crank/alternator ect.

so if you want to put a fwd pump on your rwd motor, you need to use the fwd water pump pulley. if youre rwd'ing a fwd motor, and want to use the rwd pump with engine fan, you need the deeper offset rwd water pump pulley.

few notes, you shouldnt really use an engine fan on a fwd pump, then again, i have seen it done, not sure how long it would last though.

if youve got an ae86 4ag, and your water pump breaks down, you can steal the one off your old 4ac if its still good, you just need need to grind/break off one rib that follows the cam overs and it will fit fine.

ST185 Aircon compressor doesn't fit the ST185 GrpA/CS engine. You need to change the adapter plate for the gas lines, the 185 one comes in vertically, the 185cs ones come in at 45 degrees counter clockwise from vertical (which would make it 315 degrees i guess)

[4agte]

on the tps thing the sensor has a different plug on the bigport 4gze to the bigport 4age

also if you are wanting to use the n/a alternator on the stock n/a position when converting your aw11 to turbo the 4agze water bypass pipe dosent have the mounting points for the bracket so you need to use the n/a bypass pipe which also has issues with the mount holes as the knock sensor gets in the way ive found

As mentioned by somebody else(cant remember who) the TA22 bonnet hinges dont interchange with TA23/RA23/RA28 hinges.

Are you sure? I posted a pic in TIO's of a known TA22 hinge next to my RA23 hinge... Unless my RA23 has TA22 hinges on it... Which could be the case as they are kinda bent and the bonnet sits up a bit (my car has a few 'dodgy' repairs from previous owners).

A bit more on Owens info: RA23/8 seats don't bolt into TA22 vice versa. Ditto for the dash assemblies and centre consoles.

TA22 seats do bolt into RA23/28, you just need to use the RA23/28 inner rails(23/28 have the belt clip attached), and the outer rails interchange, if you want to have either side levered or front levered forward/back movement.
