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.

how would they know if u put a turbo on it? just put the boost down to nearly nothing when they do the "hp" check.

That's just not the way it works. I need my car street legal, end of story. To do that I need to know (from Toyota, written) how many hp the chasis can withstand.
