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.

I've told people before the chassis is the same on all models unless there is added reinforcement on the chassis added after the initial construction. An example of added reinforcement would be like the Evo and the Lancer, they are the exact same chassis on the exception that after production the Evo chassis gets the seams welded together to add 50% more rigidity to the chassis. I don't believe that Toyota added the welds but we don't have GT-Fours in America so I can't check.
