Celica GT4000 (GT8)

[CelicaGT8]

Heya,

Im putting a 1uzfe into my 165 gt4, however it has a buckled chasis rail.

Now it cant be straightend, a bit to bad for that, it hasnt affected anything from the strut tower back (the tower is ok)

should i cut off the crap bit and weld on another one, or what do you think about space fraiming?.....

This is a long term project of mine, but this is something i need to sort out soon as id have to have it sussed before i start mounting the engine.

Also, does anyone no a certifier? i need to have a chat with one regarding all the bs to get it street legal.

Thanks

get a panel beater to look at it, on my AE104 the LF rail was bent, the inner, top and a bottom pieces were straightenable, the outer piece they put another 'section' into, sounds similar damage. they joined my rail just infront of the strut tower.

now is this a 4wd or a rwd project? little off topic but im curious i didnt think the 1uz can fit on the 4wd gearbox due to the Xfer case

[RomanV]

Unless you've done a lot of work on the car already...

Will it not be easier/cheaper to just get another 165?

[Mr Revhead]

or a easier to find and cheaper st160/162
use the 165 as donor and sell off the unused 165 parts

[mr30%jr]

sounds like it might be a rwd project in that case you cant swap the rear diff mounts n shit.

if its just dented i wouldnt even worry

[levinguy]

its rwd, and its more bent/buckled then dented, would be easier if you saw pics.. spaceframing it looks easier to me because of the whole lack of suitable crossmember and useable steering rack.

theres already the whole rear diff setup in the 165, would be proberly too diff,icult to put it into another 162 shell, no where near the same from what i've seen.

and 165s arn't too easy to come by from what i've seen.

If its anything like justens group A 185 Gt8 in Australia, i REALLY hope you have deep pockets , and very close engineering friends ..

That thing has been extensively modified to fit the running gear AND be able to handle the abuse ..

[Mr Revhead]

if its too hard for you to swap the rear diff stuff into a 162, then stop now.
they work you have to do to fit the V8 would be more than that anyway. and your talking about spaceframing....

im not saying you HAVE to use a 162, just suggesting it as you will have more chance finding one of those at a bargin price than a 165

im not saying its harder to swap the rear diff stuff into a 162 im saying it would be eaiser to space frame the front of the 165 which he already has(regardless of the bent chasis rail), then you would have the rear diff setup already in there to be modified (the standard diff would never handel the jandal)

i was just about to say how nice it is for people not to be saying to not do it/being negitive in general as per the norm on toyspeed, but instead to be suggesting ideas....

its not my project, but im not doubting this guy can't do it, have u seen the differences in the rear of a 165 compared to a 162? to me it seems to be far more logical to start with the 165 even with the buckled chasis rail

[Mr Revhead]

as i said i wasnt saying you HAVE to do it that way
i was just pointing it out as an option

[mr30%jr]

yea i dont even know if revhead knows the difference.

theres not even any tunnel space or room in the rear for the diff.

go hard.

it depends how expensive you want to make it. i bet it can be done on the cheap if you know the right people. this guy has done some nice work on his rona.

[CelicaGT8]

Owwww k

There are a lot of replys today,

FIRST OFF

A celica GTR, SX, ST, ZR, and GT use the same body shells with different bolt on parts. A GT4 is completely different!
You can not bolt a diff from a GT4 into a non 4wd model, theres not even a tunnel!

There where.... 5000? of these made?
how many left? i no where 6 are.

Now that i have that out of the way...

Im a mechanic, and have good engineering skills.
Im going to make it RWD, the standard diff wont handle if ofcause, iv made a rwd gt4 before by removing the front shafs and locking the center diff... the rear diff didnt like it - Had it at supra fest last year... blew it there too.....

Im using a 1uz with custom bellhousing with a supra w55.
Its simular to the GT8 in auz, but ill leave it na for now, then supercharge. no turbos, they piss me off.

It really isnt going to be to hard to do... just lots of time and money, but not big money... maby 5g

will upload some pics later...

[Anth_555]

im a panel beater i would say get a st162 and replace the bent part of the chassie with and undamage section form the 162 . as fair as i know the front of the car is still the same 4wd or fwd.

[Mr Revhead]

im well aware of the difference... just if your.. oh ffs never mind

[CelicaGT8]

if its too hard for you to swap the rear diff stuff into a 162, then stop now.


screw that for a joke lol.
Its ok mate, we all have bad days

anyway....

Yea i have a rail from a 162 and the front sitting infront of it atm, but would you join it b4 the tower so that you dont have to touch all the wheel geometry etc, and would it be strong enough after you grind back all the welds to keep it looking prety?

and welding to something that thin.... would u use mig? thats alot of welding, id want to make sure i get the penitration without blowin holes in my baby.

hope to put pics up 2morro

If you're worried about welding frame rails then I'm going to go ahead and say that you shouldn't even be contemplating space framing the front. Even if you weren't worried about welding frame rails, I'd probably still say that actually, because it's going to be way more work than you think, and while you may have some 'good engineering skills', I doubt you have the experience/knowledge to understand load paths or other important design factors for designing and manufacturing the major impact absorbing structure of a car, not to mention the half of the car where most of the safety-critical stuff happens (braking, steering).

If you're really intending to do this properly, the first people you talk to about it shouldn't be an internet forum, you should be talking to a certifier who is licensed to deal with major chassis alterations.

[matt dunn]

If the rail in the front is damaged, it wont pass a cert, even if it has no effect.

A decent push on a chassis rail with a jack in the wrong place will need a repair to be certed.

And if you think you can fit a W55 in the tunnel of a ST165,
without raising the car 2 ft higher than stock to fit it under there,
your way off.

[mr30%jr]

who said he wasnt making a new tunel for the gearbox. youd need to there isnt any theres only a lil hump for the Xfer case.

i think people who havent even seen a st165 should have way less of an opinion.

[Anth_555]

yes you use a mig and you do grind them back ( you need someone with a welding cert to do this ) try join it where theres a factory join if not join it where it is easyest
