so its got no carpet or sound deadening already. pull out the dash and remove the heater parts and venting.stereo and all your speakers and put it back in.no back seat.unstitch the mounting for rear speakers exposing your rear strut tops. carbon headlight covers are cheap and sun roof too if you got one. replace seats with light weight ones. remove abs if you got it. alloy or carbon bonnet. fibreglass mirrors. switch to manual rack(depower your power one if you have to. you can run electric power steer like in mr2 but its expensive)means you can remove the p/s pump and aircon pump and the bracket too. remove your airpump and all emissions junk. remove the four tow points and put in two omp or something tow hooks. light weight wheels and lexan glass as mentioned. and cheapest weight loss is round your waist. i lost 25 kilos not for that reason but im sure it helps. and 200hp could be possible i guess with a hard cor bridgeport or if you dont care if the motor lasts j-port

 

do you have to remove the dash to remove the heater unit or can you get it out?

if not how many bolts hold the dash in and where are they ????

I undone the ones i could see but it wouldnt come out so i guess there was hidden bolts holding it in???

 

There's bolts everywhere. Do you want to remove the heater core or the entire air mix motor unit? To remove just the heater core, it is not necessary for the dash to come out.

The top garnish panel by the windshield must be removed and there are a few bolts up there. There are bolts on either side of the trans tunnel behind screw in access panels. Four bolts by the doors, and maybe a couple more I'm forgetting. I've only had to remove one dashboard in an FC.
