Hello everybody! I have a few questions that are probably pretty stupid! Seeing how i've only had my 7 for about a year and am still learning about all the querks of the rotary engine. I have a 86 gxl that i have recently put a street ported motor in. i have a cone filter, pacesetter header, no cats and duel 4.25 ince exhausts'. No what else can i do to free up more power. i know that the stock ignition is pretty good but would consider upgrading to an msd ignition! And i hear that upgradin my injectors will benifit aswell, but what size do i put in and why can't they all be the same size? Just a couple of quick questions, any help you guy's have will be greatly appreciated! thanx

Hmm... I don't know too much about N/A's, but I'm pretty sure that running dual 4.25" Exhaust with no cats probly means you aren't getting enough back pessure to open you're Auxillary ports. I think you would be fine with 2"- 2 1/4", unlesss of course when you say exhaust you mean mufflers, in which case that is probably ok.

But I'm not sure if I street ported N/A retains the 6 ports, or becomes only 4.

 

Even with the 2.25" exhaust I don't see how his aux. ports are opening. If they aren't opening then your missing where your car is best at.

 

yeah i mean muffler's. can i put a turbo on my car? what would i need to change?

 

ya know i didn't think that back pressure would make a really big difference. insn't their anyway i can keep my 5th and 6th ports open all the time. would that give me more power? And also how can i gain low end power?

 

1. If you want a turbo, sell your car and Buy a TII.

2. Ditch the pacesetter, and go with a racing beat header. Pacesetter sucks. Get a real straight pipe instead of just hollowed cats.

3. Find a way to operate your auxilary ports. Either wire them open, or use an electronic method.

4. Add a CDI box, such as an MSD 6A, or even better, a Crane HI-6.

5. Do NOT upgrade your injectors. If anything, clean them. Perhaps use a fuel control device, such as the Apex'i S-AFC, to tune your fuel delivery to make some more power. This would require dyno tuning.

6. Lightweight flywheel and a decent clutch. I recommend aluminum, and an ACT clutch setup.

7. nitrous oxide injection. I am developing a VERY good setup for this, so email me at shutup_billy@hotmail.com for more info, and visit my nitrous write-up at 1300cc.com.

8. Port your intake manifolds, and perform the TB mod.

9. Port your motor.

10. Add some pineapple racing auxilary port sleeves.

11. Add a supercharger.

I can keep going... how about a budget and a goal for power?

All of these mods can be found more in depth through the convenient search button located at the top right hand corner of the forum.

 

Buy a piston car.

 

I have no cats. thanks for the advice everything on your list is in my range accept for the supercharger. And i don't ever want another piston car. the last one i had caught on fire on the whitemud here in edmonton.Well i guess i had it comming though it was a chevette
