99-mod Celica ST chassis vs GT/GT4 chassis Options

[Illyont]

Hello!

Overseas in cold Norway we have a bunch of stupid laws. One of them is:

You can never add more than 15% horsepower above stock for your model car. If you do, no more street legal.

Anyway, I was talking to them today and I got them to agree on this:

If I could get a written statement from Toyota that the chassis on a regular ST (AT200) would be able to hold x amounts of whp. They could register the car as a street vehicle. So I drove to Toyota and asked them. They didn't know....

If anyone should know, it have to be someone on this board. I know it's a pretty long shot, but I have to ask. If the chassie turn out to be totally different then OK, but if they are the same, or atleast if the ST chassie can withstand lets say. 300 whp from a tuned up 3S-GTE then wow, great.

I will probably get like 20 replies saying:

I have a 94-99 Celica ST with 3S-GTE swap and my car is doing just fine. That just doesn't cut it. I need to get the statement from Toyota, but before attacking them I need some cold hard facts first.

The only way to truely find out is to check the GT-Four forums or to call the original manufacturing plant if the chassis is indeed the same, I would say you could go off othe chassis code i.e. ST, but the AT series is the same chassis also. The chassis could be the exact same as the Gt-Four but you can't get past the numbers stamped into the metal, legally. I don't know anything about Norway but can you get a chassis shop to stregthen it for you and provide a authentication number, we can do something like that here, it's a sticker that sits above the inspection. I can't remeber the name of the plant all I know is it was originally maufactured in Japan and shipped else where for modification like the convertibles. I still think you might get hung up with the AT code. If anything E-Mail Toyota Japan with the question and keep hounding them until they give you an answer.

To get the car registered and street legal I need to find written proof that the chassis can withstand the pressure from the engine. What numbers and chassis code is stamped on the chassis doesn't matter. This can come from either A) Toyota or B) TUV in Germany. If either of those can give me written proof that my car can have 260 hp without breaking, I can have it on the street in Norway. Option A is prefered, because TUV bills you 4 000$ for ONE check. And if you need more, then you have to pay up another 4k$.

As already said I'm gonna continue hammering on Toyota to make them spill their guts sooner or later on this issue. It would really make a difference, since it would then be piece of cake for everyone that wants to do this after me (in Norway atleast).

I don't think we have a single GT-4 in here, and not many GTs either. We have some, but 97% of them are stock, and the last 3% are more or less illegal. We have alot of non-GTs though, about 10 (6th gen) only in my city (17 000 people) Suddently all of those can get a motor swap just like that.
