What can get you extra HP on a GXL???
I want a GXL for a car. Probly gonna have a 86-88 so 142hp stock. What would I need to get some more HP. 200hp would be GREAT but that would probably cost me quite a bit. What will I need to do. And will I need fuel upgrades?
What about a supercharger. I guess they run about 4-6psi. I figure "around" $3k, How much HP can you get from one.
Also what is a good size wheel for a FC. I'm thinking 17"
Also I'm thinking full exhaust. either hi-flows or no cats. Possibly RB

Start with the basics. New intake, air inlet headlight cover, gut your cats, get a new exhaust system, get a different ECU, and run a lighter flywheel. Also, there's a site that tells you how to modify your throttle body: http://www.k2rd.com/FC3S/HOWTO/TBM/tbm.html
And that should free up some horsies. I know a guy with a supercharged RX7, and it runs great. Of course, I'm gonna buy it off of him...
After you do those basic mods, you should get about 180-190HP...or so I've been told. I just got mine and haven't started playing with it yet, so I can't be an accurate judge.

You should have 170-180 RWP w/o the supercharger depending on what shape the car is running in & what mods you used. If you check out mazdatrix.com & look at the racing section you will see the full dual racing exhaust setup that dynos a 28% increase in RWHP. Thats what i am saving up for as we speak. Its expensive but hopefully worth it.

that out of a GXL would be great. And if I ever feel a need for more ill charge it, or replace with tII engine ecu tranny and dif i im a real speed freak. That is if i dont find a good deal on a tII and decide i can afford insurance ;-) thanks guys

Damn man, I thought I was the only one on here 24/7, hehe. Ya I am going to get my HP on my 88 GXL as much as possible with basic intake, exhaust, pulleys, etc then if its not enough its NOS

Second. Will bigger plug wires and different plugs help?
Third. What is the general consensus on porting?

Second...plugs & wires will prolly not give you any noticeable gains but should help your car run better. I like NGK.
Third...porting prolly shouldn't done unless rebuilding anyways, & just a mild street port for a daily driver.
Hope that helped

Former Moderator. RIP Icemark.
Heck, just replacing the fan with an electric one is worth 10 HP warm on that car.
Header/exhaust, intake, fan, light flywheel and slightly advanced timing (useing preminum gas) should all and all get you about 25 to 30 HP right there.

You'd need to refill like 4 times just starting it ;-)

i know i was joking. Any other ECUs can compare to that one or what? Its not gonna be very crazy so haltech just goes down the drain but its nice to dream lol.
And which exhaust do you guys like. What about Apexi N1 Duals. I like em but heard theyre loud and heard RBs are gay cause theyre too quiet.
Figure 165-200hp FC

I have yet to see a dyno for that computer [other than MD Racings] proving that the computer adds 25% more torque and 25HP. He has the most expensive autocross version too...

Good question...
Where can we get the best "possble" supercharger for the 2g rx7s? "Atkins" make them I think, but is there any others? What are the figures of power increase? Realiablity?
Anyone konw?

Was just real irritated about getting my water pump pulley back on but now its ok, just snapped the bolt to adjust the alternator so can't figure out how to fix it. Got the broken part out, just don't know where to get a bolt.
