I want Horse power
 

Alright here we go i have a 1988 mazda rx7 convertible and i also have a 88 coupe both n/a which sucks which translates into insurance sucks.So i want horse power what can i do. I have an electric fan should i install it and i looked up superchargers on ebay there electric and preety cheap what else can i do to get some extra zip. Oh and the coupe is my parts car i took out the engine and am going to rebuild it i did a hand compression test and it seems like the apex seal on the front rotor is blown. I am going to sell the motor so it will be up for grabs real soon. Im 16 and really mechanically inclined took the engine out and apart my self just dont know whats the best way to get horse power help me out. My car is like a drug i work on it when i get home till my parents drag me from the driveway.

Dont buy one of those electric superchargers. They simply dont work. An electric fan is ok as long as it flows enough air to keep the engine/radiator cool. Best bet is to buy exhaust, then intake, and finally ignition wire upgrades. Doesnt necesarilly have to be in that order. Exhaust will help the most.

need some power
 

Okay great thank you i already have an exhaust upgrade and a intake upgrade on the coupe that i could switch over in like ten minutes, but I dont have the ignition wire upgrades were could i get some and were can i get a supercharger thats actually worth my buck.

Lets start with this, do you have a power goal in mind?

the 1988 mazda rx7 conv is by factory the slowest rx7 ever made. it just as fast as a 1st gen 12a. tho i own and love my 88 vert.

u need really big ports (n/a) or a turbo engine.

my 88 vert has a big street port with racing beat exh. its fun to drive

The thirst for speed
 

um i would like to get over 200hp I think the car out of the manufactures pushed 145 but I only got 1100 bucks to work with any ideas?

power
 

Is that to high of a goal. Any little bit will help i just priced a true supercharger and was shocked by the price and i thought skateboards were expensive i guess bigger toys equals empty pockets and long night shifts at captain ds lol. Oh and Ian im praying for caleb any updated news on him.

i'm not too familiar with n/a's but 200 rwhp isn't hard at all with a TII.

t11
 

Man i wish i had a twin turbo that would be nice but i havent found one for sale yet i guess everyone like em lol but i have thought about conversion. JDM offers a twin turbo with trans and ecu wiring uncut for about 1300. after that I would need a hood and thats about it but it is alot of work I hated unbolting that damn air conditioning bracket on my coupe that alone took 6 hours and the engine took 8 to get out.

are you set on a supercharger or do you just want power?
most people swap the turbo-ed engine from rx7 T2 model.
then your exhaust and intake and ignition wires.
not sure where that will put you as far as horsepower but you should be close.
if not then porting always makes for more fun.

power
 

The engine swap will be a summer thing i want to find a better candidate than this beat up convertable plus i like the coupes better. Do you have any idea on were i could get a supercharger. I found one on ebay for like 300 bid still going the thing is huge. and do you agree that the electric superchargers dont work.

no, electric superchargers are a joke. if you're going for 200, a good port job should get you pretty damn close...

To put it bluntly, that's not enough money.

If you really want 200 wheel HP, you will need a port job (it costs more then $1100 to rebuild a blown engine), a nice exhaust with a long tube header, cone filter and a standalone with good tuning.

I agree if you have a low budget small bolt on power is what you are looking from but you said you are going to swap out the engine this summer i would sugest save that money so you can get yourself a nice ported engine because when you port a rotary engine you need to over haul it. so save your money then get yourself a nice ported engine, then have more base line HP to start bolting stuff on, as for the super charger, if you want power on all your RPM band get a good super charger you can find one used for about $1000.00 but if you want some get up in the higher RPM go with a turbo. up to you just some thing to think on my .02
:icon_tup:

A supercharger is almost never the way to go when making power on a rotary. Only under very specific circumstances (ie. you got it dirt cheap).

ever consider doing a swap? buy a ls1/t56 combo off ebay or other forums for 2500-3000 and then you will have a car that will beat anything :)

sorry i already sold my jdm tt complete swap to a guy in manitoba that could have been a good alternative for you if you wanted to stay rotary.

TII doesnt equal twin turbo. not sure if he understands that. im reffering to the first few posts. im too lazy to read everyone elses. If you're motor is out, port it. really, just get a blown 13bt and rebuild it. you could do all that for 1100 bucks easy. rebuild kit is like 400. my 13bt motor was 200 off craigslist. use you're head and be resourceful. You dont need to go out and buy a full motor for 1500

Better idea
 

Buy a s4 13bt engine for $750.00 from Gspeed and try to get your hands on turbo tranny( I have seen them for $200.00) Then drive like a fairy untill you can change the rear end and drive shaft :lol:

i agree
 

i have an s4 motor in my s5 t2 i have fmic bigger injectors bigger turbo and haltech standalone im making right over 300 whp
i used to be just like you with the n/a tryin to make it fast when i was 16
so then i just made it super clean nicce paint wheels and headers and exhaust made about 180hp and sold it for double what i paid the bought a t2 i prefer you take the same route!!
