Probably true... but that's also something that affects a 2400lb car a lot less than a 3300lb car.

And mine is leaking to the point it borders on ludicrous. And i don't feel like paying to fix it. If done right it should only suck while parking. Even when i was fighting the pump in my old car, it was easily manageable once going faster than 15mph. This car is easily 300lbs lighter, and i won't be fighting the pump. Was more curious about how much it weighs.... i'll find out if nobody has input within a week.


Not to pick on you or anything, but I don't think that the solution for not having enough money to fix something is to yank the system out. Your car will eventually be a worthless shell if you keep following that line of thinking. If you don't want to pay to fix it, get a set of BGBs and some tools and troubleshoot the problem. You may find out you just need new hoses and not a new pump.

Also, taking out power steering doesn't give you manual steering, it gives you broken power steering. To get the same effect as manual steering, you would need to swap in a manual rack. But that might end up being the same or more money as just fixing the power steering.


No i understand what you're saying. But what i'm saying is that i'm not about to pay the money to fix something that i'm not a fan of in the first place. It's not that i don't HAVE the money, it's just that i don't WANT to "fix" it. I just dropped $500 on tires for my $600 car. If i wanted to fix the power steering, i would.

I would swap to a manual rack if i 1) could find one, and 2) wanted an even slower steering ratio, which i don't.

What i'm doing gives me a manual rack, with the bonus of having the quicker power rack ratio. I'm not saying just take off the belt or anything.... i'm taking off the pump, and recirculating the rack. It's not broken anything, it's properly "de-powered."

I know it's the hoses. Both the high pressure and low pressure hoses are leaking. The pump works fine. I paid $600 for the car, it IS a worthless shell from the standpoint that nobody would buy it. But that's fine, it's NOT meant to be a daily driver. I don't really care about the resale value, it's a track toy. And from that standpoint, less weight = better. The car has an end goal of under 2400lbs w/ a gen3 swap. :D

The A stands for 'Adovansu' or advanced and this is the first ST185 model to use the widebody shell.

From René's site.

Anyway, getting off track from the thread. Pretty sure the A is wide body only.

I dont think 1100kg is attainable without swapping in some light wiegt body panels, glass, gas tank and or suspension supports. Its not always cheap but focus on some lightend rotating parts ie, wheels, clutch flyweel,driveline, brakes. This may along with stripping the car could give you a 1100kg feel

At the moment i have:

No PS, no A/C, no interior heater or fan, no intercooler, just the engine under the bonnet.
Carbon front seats, no back seats, gutted rear.
Light flywheel and unsprung clutch
Lightened mr2 alternator bracket
Coilovers
I'm simplying all the wiring of the car, no more fuse boxes etc...
No more sound deadening
No more alarm
No more central locking

Also it's a 1987 st165, so no side bodykit, no transmission cooler, no ABS, no sunroof.

I'm hopping to get around 1150kg without the driver. Keeping the dash and door trims.

Do you guys think it's attainable?

I'm thinking about switching to manual windows and side mirrors. Do you guys know what's the weight difference?

Also what is the weight of the 1st series 1987 jdm st165?? Was it 1350kg? does it includes driver/fluids?

Thank you :P

How about carbon driveline and lighter wheels? Bumper supports? Stereo? Sytem ten in 185 is heavy. Swap out some glass too. Door and window control motors etc will lighten it IMHO about 15-20lbs, I think you can get to 1150. What do you wiegh now?
