1UZ into RA23/28

[fuzz!]

while that second picture does realise just how long the engine is in the A23 bay, without the fan clutch on, there is more than enough room for the radiator and thermos. length isnt the problem.

the problem is east-west clearance, the steering box, and the headers. dropping a 1UZ into an RA23/28 might be perfectly feasible, but you would have to take the following into account;

* a suitable crossmember/steering rack combination is needed.
* a suitable sump setup for that crossmember/steering combination
* a custom swaybar to clear both of these

but hey, just do that, then get your manual conversion, custom driveshaft, suspension, radiator/thermos, wiring, brake upgrade, diff, rear axle and rear brake setup sorted.. then your interior, paintjob, wheels & tyres, window tinting, soundsystem, fluffy dice and led zep cd in order and you're home free.

RA60 xmember and Power Steer into Ra28.
Idea taken from Stepho's page parts are borrowed from Celica spares for fitment.

See more detail here My mebers ride thread

EDIT: and the ra28 control arms are the same length as ra60 allowing me to still use the xt130strut/hilux/pug brakes.

That is my plan exactly... even down to the choice of CD

I dont want to think about how much its going to cost me.
The front brakes and suspension has cost me ~$3000 and thats not finished yet.
R&P was cheap to do, just took a lot of time.

I wonder what your bumpsteer & ackerman angles will be like.

[TA-022]

still to measure.... but how?

no net till this arvo so ill get more detail then.

ahaha nice.. i forgot chassis re-inforcement, but you've done that already

[barned01]

very interesting on the R&P, would also like to know more.
this might mean the ra60 strut might be a little better suited also considering the track is pushed out by 80mm according to the web site (which makes the positive camber issue ordinarily from the ra60 strut on a ra/ta 23/8/40 crossmember not as much of an issue...)?, then that solves the brake side quite easily (cruz and the r33/z32 brake brackets for instance)...
now with the mx62 swaybar being 25mm further towards the front than the 23/8 swaybar, is there a slight possibility the sump might fit in between this gap?...
damn it, i want to try this out (the steering part for the moment, not the uz part) but won't be able to for a couple of months (stupid 100k service on soarer )

I wonder what your bumpsteer & ackerman angles will be like.

As long as the height of the crossmember in relation to the chassis and the strut top spacing is similar it should be identical to the donor car as you are not changing any of the mounting points compared to the RA60. If the car is lowered or you use different struts then you will have to look into the effect this will have. I have done efffectively the same swap into my Starlet with a TA63 crossmember, bottom arm angle is the same as in the TA63.

Yeah I agree, ackerman will not change unless you are changing the steering knuckle length or moving the rack in relation to the xmember.

Bump steer will depend on the angle of the control arms but this could be adjusted with RCA's.

[barned01]

fuzz is that engine mounted up to the crossmember?
if so could you do a quick measurement for me?
if you were to draw a line down the crossmember that lines up to where the swaybar mounts to the control arms, could you measure from this line to the front of the sump? i would like to know if the mx62 swaybar with it's 25mm further forward than the standard one, might be enough to clear the sump or if the custom swaybar is the only way.

[TA-022]

sweet... xmember to strut top is about 10-20mm further apart in ra60 compared to my setup. 10mm steel will be used to redo xmember mount holes effectively bringing my setup back into ra60 spec.

Will have to check ra28 manual knuckle length compared to ra60.

So in theory if measurements are close close close to equal in my setup compared to stock ra60 then i should be fine?

Thanks

no it wasn't mounted - that was just a quick test fit using the original crown mid-sump and 18R crossmember (it fit surprisingly nice). i don't even have that shell anymore so i can't give you measurements i'm afraid. the RA23 i have is still home to a stock 18R-C.

BUT... i did throw in a TA23 crossmember, and while the mounts lined up quite nicely, the swaybar interfered with the sump by a fair bit more than 25mm. from memory i would say at least 100mm. the front sump setup for the 1UZ comes pretty far foward - check out pictures on www.1uzfe.com:

This is true.

Bump steer will depend on the angle of the control arms but this could be adjusted with RCA's.

Im pretty sure bumpsteer is also effected by positioning, length of the tie rods and rack.

I measured my setup before & after using some angle fixed on the hub and a string line down the length of the car.

Fuzz!
How were you planning to mount the engine to either of those two crossmembers?
Thanks,
Mitch.

custom mounts (at least one half) are usually required for any conversion like this.. best bet is to grab some of the wing/ear style mounts for the engine side as they're quite versatile.
