1UZ-FE into TA22

[camshere]

Yeah, the chassis was extensively modified to handle the targa top and the intended V8 when it was take off the road, over 25 years ago. I will be doing some research into current ways of strengthening chassis however as i've heard stories of some old-school strengthen methods that took away most of the road feel/feedback through the chassis - something i'd like to limit if possible.

There are some pics of the actual mods here:

The big cross bars under the gearbox are what i'm worried about - if anyone can enlighten me on the pros/cons of such work then please feel free.

If I was in your position this is what I'd do.

Download the pre-approval mod form, fill it out with all your plans, send it in, wait for it to come back.
Get in contact with Jack Apgar (he's an engineer in Duncraig), he knows this stuff very well and I'd say he'd be very interested in doing the engineering on this project.

You may even want to talk to Jack before sending the form in, so that you can state on it that the modifications already performed are structurally sound etc.


And do your best to try and find a piece of Toyota documentation that says that the TA22 is >992kg.

um, have a look at the TA22 Specifications thread. i seem to recall reading that a GT was just over the 1000kg mark....i'll see if i can find it.

here ya go

this bit may interest u

GT - 1005 kg
ST - 985 kg
LT - Automatic 980 kg
- Manual 970 kg

isn't there an older style toyota v8 that is ~3.5 litres?
Would be hard to find bits for or replacable parts alas. but might fit in your weight band and definately would be different (well different v8 anyway)

other theory is the rover 3.5 alloy v8 if you still wanted 8 cylinders, but i have heard some things need to be done to them first to make them reliable.

CrUZida, Grega - awesome infomation - i might speak to Jack before i send in a pre-approval form as there is bound to be extra issues with the engineering mods already carried out and associated flex tests etc etc. It actually passed engineering for a V* and the top about 25 years ago, but i don't think that counts for much. Does he have a business name or can i just contact him from his name?

The car was originally an LT i'm pretty sure - which would put it under - but i've seen the GT vs LT argument rule used to put bigger motors in race cars and rally cars so maybe i can use it to justify up to a 4020cc motor.

[camshere]

As for the older style V8s from toyota, the only reason i'd consider the 1UZ is because it is all alloy and fairly light for a V8 - the old cast iron ones are a fair bit heavier from memory. Plus i'd likes something newer and more reliable/easier to get parts for.

There is a black RA with a older Toyota V8, but apprantly to handling isn't that flash, to say the least...

[JustCallMeOrlando]

I'm pretty sure it gets based on the heaviest spec in the model, or at least it could be argued that way.

[brett_celicacoupe]

the extra weight would most likely have come from the power windows and all the other little add-on goodies. i doubt the chassis would be structurally different between the GT and LT's.

im sure you could argue that point

[camshere]

Good point, GTs are technically the same chassis. I've been reading the NCOP codes, and the LA2 records would allow the 1UZ if the weight was that of a GT, but not super/turbocharged

I wonder, if once its registered under the LA2 spec, if you can then apply to fit a supercharger under the LA3 section. That would be a nice little trick, either that or i might have to go for a small, stealth install after the car is registered...

I think i'd be happy with working the NA motor if no forced induction alternatives are viable anyway.

[brett_celicacoupe]

do you really think you need a supercharger?

it would be un-driveable enough as it is

The older Toyota V8's are probably smaller and lighter than the 1UZ, they're all alloy too, but pushrod.

If you're really keen to have this super/turbocharged down the track, especially given the targa roof, perhaps it would be better for you to try to get it registered/engineered as an individually constructed car which would circumvent a lot of these rules. More expensive yes, but providing you can ensure everything is engineer approved and structurally sound, the sky is the limit.

[CrUZida]

According to the NCOP its actually based on the lightest model, ie the sedan, not the wagon.

But is this car registered as a GT or an LT, or does it say neither?

You could just says its a GT

EDIT: Heaviest sedan version of the model - but NOT including aircon/towbar etc weights.

[CrUZida]

Oh, and also remember that the weights the DPI has listed may not be the same as what Toyota claimed them to be.

Might be worth a call to them to find out what they have your Celica weighing in at.


And just look up "APGAR" in the business white pages.
