yes. money is always an issue. i started with an exhaust, and the intake. then spent some money on new performance tires. now im getting some headers, and maybe changing the cat converter. but everything is done in gradual steps. i just wish i would win the lottery and then i can bring my car to a local ricer shop and say "supe it up". hahaha

Ya i know what your saying about the lottery ive always wished that too. but anyways considering the fact that ive never put on aftermarket exhaust or intake if i was to put these on am i really going to feel a difference in power or are they mostly for looks? Oh ya one more question, considering that my supra is a non turbo could i put a turbo exhaust and downpipe on or will it not fit. i know these are dumb questions but i need all the help i can get. Thanks

First things first!!! Check and replace as needed...ALL the hoses and belts. Timing belt??? when was last change??
ALL the fluids !!!! Radiator cap and thermostat. Any funky looking electrical connectors and wires. Battery terminals?? Clean??

Brakes...brakes....it don't matter how it runs, if it won't stop !!!

Front end parts, and alignment.

Radiator??

All of this so you can DRIVE the car without the help of a tow truck !!!

yea he has a good point. make sure you check out the condition of the car before you add anything. i started adding my exhaust then my intake. and realised i needed some repairs. so i spent a lot on repairing, and replacing parts. getting new brake pads and calipers and belts. repair and make sure the car is in good working condition before you add anything aftermarket.

Well...you start your own thread !! Or you check this forum, or all the others, for their 'performance upgrade' sections.

Or...sell it and find a YUGO !!!!

About 10-15hp is the 'general' gain, assuming that the car is in good running condition, and the existing intake and exhaust are in good condition.

If the intake or exhaust are in poor, or restrictive condition, you are losing hps, so new systems will feel like a bigger gain.

ie: when I got my '89 N/A, the exhaust system was restricted starting from the cat back. Someone had done a crappy job on the system.

The pipes went from 2 1/2", ran about 18", then down to 2 1/4", ran back to about 12" from muffler, then down to 2" on into the muffler, and coming out the muffler was 1 7/8".

When I put a new 2 1/2" Magnaflow cat, resonator, pipes, and muffler on....WHAT A DIFFERENCE !!!!!

Headers (OBX) are next. I expect to gain at least 10hp from them.

PS. top speed before new system, 125mph....after, 140mph.
(disclaimer...not recommended for everyone...wear a helmet !!)

yea make sure that the car runs good. im putting in a new magnaflow cat soon and some headers (OBX as well). and that sounds like there was a really shitty exhaust job done on your car man. so much restriction. but its good to hear that you changed it all and gave it some power!

just a question mrnickleye, do you know any good stores online that sell the magnaflow cat converter? im trying to find some places that sell them. thanks.

Nickle and Bullz eye are right. Trying to squeeze power without getting back to stock condition is stupid. You'll bolt on a bunch of shit and melt your block because of a stupid mistake like a poorly functioning water pump or belts that are crap. Power can be as simple as changing your spark plugs (of course to iridiums) and gapping them properly. Seafoaming the engine. Changing ALL the fluids. hoopties don't make power. Cars in good condition with proper modding do.


And just for the record, Nitrous is usually just a show off toy... unless your crazy and decide to push the other button... the one that doesn't say purge. Hope you popped for the MHG and have your compression proper.
