I own a 1989 RX-7 GTUs N/A with 144,000 miles, and I'm looking for more power. The only problem is a shortage of cash. Right now I want to get it rebuilt+street-ported, but that won't be for a while.

Anyone have any suggestions about what will give me the most power for the least amount of money? Also, where can I get the engine rebuilt for fairly cheap? I'd do it myself, i just don't feel confident about doing it right, and the last thing I want to do is screw-up my engine.

Less weight = zoom, zoom



Where are you located?

 

whoa, another gtus. you relize there is only a couple hundred of those right? very rare! don't screw it up!! :smirk:

 

I'm pretty sure there's a step by step thread about this under FAQ's.

 

i'd love to have a GTUs.... N/A they can quick but not super fast. my GTU was pretty quick..... i wouldn't strip it down or anything. if you want a fast car just buy a TII

 

lot of the time if you do all the little things it helps in the end.that is what i'am doing with my 91. taking one step at a time, when i have money.

 

well first thing 1st. with 144k on ur odometer get a rebuild, then start doing some freebie mods from there.

 

I've only got about $550 in intake and cat-back. That should add 10-20 HP. If you want to dump $1200 on exhaust you could get a 35 hp gain.

 

doa rebuild first, then start with the little mods, intake, exhaust, take cats off, remove ps. **** like that

 

Is a rebuild all that necessary? I have over 140k, and the compression is "really good"-mazda mechanic.
