Maybe a dumb question, but just looking for opinions. My friend has a 86 N/A. He wants to make his car as fast as possible, streeable. What should he do it? He has $4,000 saved up for the car, I was thinking maybe v8 swap? He wants straight line power, maybe turbo II conversion? What do you guys think? He said he has to keep this car.

If he wants straight-line speed for $4k, theres a number of ways to do it. It depends on your friend. Is he diehard rotary? If so, a TII swap + a few mods can be done for ~$4k, and be decently quick. He could do a v8 swap, but that discussion belongs in the "other engines" section - most of the times that v8s are brought up in this section, the discussion gets a little.... heated.

If it was my car, I'd have the 6port engine rebuilt with a good sized streetport, and turbo the 6port engine. But thats just me. Opinions are like belly buttons, and all that.

Also, define fast. He wants it to stay streetable, so I'm going to assume that the car will be daily driven, or at least driven often enough to make reliability an issue as well. How fast does he want it?
To be honest, I don't personally see a reason for needing a 12sec or under car for the street. The only time you get to use that kind of speed is when you're doing something the cops won't like anyway.

hmmm, i have an idea.........he could get the atkins supercharger for the stock EFI, and the racing beat or mazdatrix true dual exhaust
http://www.camdensuperchargers.com/


the supercharger is like $3000 though and the exhausts are about $1000-1200 from header to tip. so very expensive

thats about as good of bolt ons for a n/a as you can do. by far no means as fast as you can do for $4000, but all bolt on and it will be pretty quick. I'd also get a flywheel and clutch.
Maybe some suspension too

will need a fuel pump, and a fuel controller probably. but that would be a sweet little car.



honestly, with $4000 and a 86 n/a. He should sell his n/a and buy a turbo II.

You could search, and read the hundreds of threads on making power out of a N/A motor...

I disagree.

First of all, the new Camden kit seems like one hell of a waste. You drop $3K and you only get 6 lbs of boost. Also, you need to run 92 octane gas, and the EFI charger kit removes your aux ports. You end up with less than 180 hp at the wheel, and you spend $3650 plus shipping and installation to get there. This is a huge amount of money to spend for so little gain. You can get better gains by turboing the 6 port block and if you do it right you will spend considerably less. Add to that the need for better breathing--a better exhaust--and the cost goes even higher. And this is to get a car with better straight line power?

As much as I hate to say this, your best bet for straight line power is an engine other than a rotary. A small block Chevy will make better power and torque, and also require less maintenance if it is set up properly when copmpared to our 13B. And the newer ones will get you halfway decent gas mileage without needing high octane gas

If you do intend to keep the rotary, go get it ported and then do a 6 port turbo conversion. You will be able to make better power than the Camden kit relatively easily.

lol yeah, after i posted this i went and was checking out their vid again.....and some of the other stuff. its more expensive for the EFI kit than I thought and not really all that great
it wouldnt pass emissions in any state because it idles so high especially.

He wants it to be able to get into the low 13's, so very streetable. He HAS to keep this car for some reason, so it has to be done to this car. He doesn't care if he goes turbo or swap or what. Just whatever he can get to run low 13's for $4000. I have been searching threads for what to do, just haven't got a clear view yet.

strip it down. all that excess interior crap (carpets, moldings, dash, etc.) needs to go. You'll end up with a much louder vehicle (from the inside), but weight savings are weight savings. In the end, the less weight the engine has to push, the quicker you will get there. I've heard that the T2 swap is an excellent base or foundation to jump up on power. NOt only do you get more power out of the swap, but with a few key bolt-ons, much more can be easily attained. Take the time to do your research and talk to different shops and people. Like it was mentioned before, opinions are everywhere and some are more misleading than others. DO YOUR RESEARCH.

scathcart

Intake filter, straightpipe, nitrous 125 shot. $1000 for everything, perfect for straight line only.
Engine will be completely streetable, no louder than stock.

I would save a few more pennys if you have the time. I would then bridge port the motor using TII rotors and 3mm apex seals and machine the rotors. Contact SonicRat about a UIM and LIM and oil lines needed for a T convershion if all goes well to he will have a kit to purchas. you then can go to a junk yard and rip a turbo off something as well mybe get a FMIC here spend $50 to rebuild the turbo get some silcone or plastic piping for IC lines get a TII MAF some exhoust of your choice lighter fly wheel and clutch "could be done on a maintnace period" and RAD a boost guage and manul controller take it to a dyno and have them tune it on a wide band and enjoy

powrdby13B

in the archive look at the mods threads...
but, for 4k you could get EMS (Haltech E6X or compatible), big injectors (1600's... jus to be sure :P), fuel pump, intake, exhaust, etc...
OR... buy a 13bt motor, tranny, driveshaft, rearend, etc and do very mild work to get it into low 13's. Like, fuel computer, boost controller, full zost, intake.

$50 for a rebuild!?!? from where?? Most people dont rebuild their own turbos.

iceblue

Ahh well lets see. I dont know off hand. My friend Carlos just came back from the junk yard with 2 big turbos off some trucks for $100 each and paid $50 each for a rebuild kit wharever her got it from. They are for his twin turbo 12A Toyota Starlet.

Ahh yea I balive most people on here do rebuild there own turbos. And we do at my house.

1. Disconnect battery
2. Install new engine



really, with that kind of money to spend.. best way to go, plus you at least know what ocndiiton you rnew highe rperformance engine owuld be too

I turbocharged my 88 gxl for under 500 dollars but I got a really good deal on the kit. But it is alot of custom fabs you have to do but in the end it is all worth it.

iceblue

They were T3/T4 turbos hibrids they costed $100 dollors each as I said and the rebuild kits were bought offline from an industrial site for $50 and the seal kits "included" were $12
