Best bang for your buck aftermarket supra parts - Page 2

all those upgrades are good. but no one mentioned cam-gears. you can get about 25-35 more hp and im not sure how much torque for upgrading these. also getting new underdrive pulleys is a big deal. if i am correct for every pound or so you lose on the underdrive pulleys you gain about 1.5-2.5 hp. i upgraded my pulleys on my 1992 non-turbo supra and i can feel the difference.

I would focus on the headgasket first. My supra only had 60K when it blew it's head gasket. Get ARP bolts and a stock toy head gasket and you should be cool, unless you want to run massive boost then I'd get the HKS metal HG. It's a pretty common deal with the supra's, the headbolts were only torqued at 58 lbs. ft. when they should have been 75 lbs. from the factory. They tend to loosen up over time and the gasket wears out, normally in the #6 cylinder. Toyota should have issued a recall on it like they did with the v6 pickups.

the headgasket and intake, a good ecu, maybe some new 50w oil and some stp. that will help you out a little. do some light weight deduction. replace some of your old piping and exuast and your car should be faster. i saw some intake parts (custom intake parts) at pepboys but its really low quality, i guess it does the same thing. its not metal its cheap plastic. thats a cheap way to get a custom intake

When i first bought my supra (it's an 88) it had a very small exhast leak that i decided to get fixed. Even though it was a small leak it was a enough to make my car sound like crap. For about $130 i got a custom exhast that not only looked and sounded way better, it sure felt like i was getting more horse power too. Im not sure if i had any thing blocking or resisting my exhast but i think the $130 was well worth it.

I agree, the 7mgte responds very well to exhaust mods. The stock piping is too restrictive. I bought my supra with a 3" muffler and it looks like 2 3/4" piping already on it and i've whooped other stock turbo supras. It could be their driving but I've blown them out so it looks like any driver could of done the same. plus it sounds good!

i'll be doing the CAI next if i can find a good write up so I can just but the right angled tubes from the store, then possibly headers.

Hi all,

I have an '87 NA MKIII which is currently all-stock, has about 90,000 miles on it. Previous owner didn't drive it much.

Anyway, I use it as a commuter car (albeit a fun one), not looking to race or anything like that. I notice that it takes about 8+ seconds to go from 0-60, which seems kinda slow (I know, it's an NA, but still).

If all I want to do is basically get its performance back up to par as when it was new (a 200bhp inline 6 shouldn't be too shabby, right?), what parts should I be looking to replace / refurbish / improve?

Money's tight so I'm preferably looking at some kind of multi-month plan of purchases and installs, and would therefore also appreciate some kind of idea as to what order these improvements should be made.

Appreciate the tips in advance!
