SR into a 1200

Before you guys bit my head off and say look at the tech section, i just want one little thing cleared up. I've read on here many times saying that you can't get an engineer to pass an SR in a 1200. Well i spoke to an engineer yesterday and he gave me the formula to find out how big i can go. For a turbo charged engine its the weight of the vehicle X 2.5 and that gives you the biggest capacity. Now the GVM of a 76 1200 ute is 1315kg. Minus 500kg for the max load and you get a vehicle weight of 815kg. So 815 X 2.5 = 2037.5 meaning i can go up to a 2037.5cc engine i.e. An SR is legal. Now my question is, is there anything else stopping me from engineering an SR into my 1200.

I know of an FJ20 turbo ute which is engineered.....I reckon u must be right with this formula...however I think with the utes they can get away with it due to the GVM - load carrying capacity.

HeathBruce is correct.

It is the weight of the Sedan that the weight is based on.

dattodude, i do know you can put airbags on 1200 Utes because they are classed as a commercial vehicle so maybe i doesn't count

Thanks for the replies guys but no one has answered my question. Have i done my maths right or am i seeing things. The GVM of a 76 1200 Ute is 1315kg. Minus 500kg for the load limit and you have a vehicle weight of 815kg. Times that by 2.5 and you get the maximum cubic centimetre capacity for a turbo engine which is 2037.5cc. Just over 2ltr. So why are so many people saying that you can't get them engineered? from what i understand an SR isn't even 2ltr, its like 1980 something cc not 2000.

geez what more do u want
dattodude already said it...

"it is the weight of the sedan that the weight is based on"

im sure ur maths are fine... BUT u have the wrong starting weight...

i have owned and engineered a sr20det 1200 ute in qld... It's was regd with the correct engine number etc, but it was technically not legal...

you are in mullumbimby
try calling ray cross he is an engineer(automotive) and supplies engineers reports for registration of modified vehicles
if you tell him what car you have and what motor you wish to fit he will tell you if it is possible and what adrs you have to comply with do this first to save money and confusion. his number is listed in the yellow pages under consulting engineers
good luck!
