ok so im looking at a 85 GSL-SE w/ a FC 13B so my question is what can i do to it? i would like to have like header, test pipe, exhaust, air intake or what ever. im new to mazda and the rotory and im sorry if this is a stupid thread/question.

 

There are no stupid questions, 1st thin is to read a lot in here, do searches on your ideas, see search button at top of page and figure out what you want to achieve, then go 4 it dude.

 

thanks for the pointers

 

It's easy to get excited about these cars, they are addictive, so have a plan.

And welcome to the Dark Side.

 

The Dark side? Well at least until you see the first ricer disappearing behind you as you leave him in the dust - then it gets a lot brighter!

 

so are they pretty quick stock?

 

Not really now, in thier day they were decent. Nice thing is, modding can be less expensive in some aspects than pistons. You can get a nearly 50% hp increase with exhaust and aftermarket carb, try that with a boinger.

Ah Just made my first good bonehead post for the night, didn't see that you had an SE. The SE comes with 135 hp stock, a good exhaust set up can get you near 155 hp.

 

boing boing lol sorry FTW

 

Quick is a relative term...

In 1984 and 85, the GSLSE's tore up the competition in speed. In stock form it's pretty slow compared to a modern Detroit V8 or turbo RX-7. My GSLSE, however, is as fast as I want any street driven car to be for my personal use, I wouldn't want it to have more power even if I could do it easily.

The easiest thing to do to it to make more power is FIRST do a full tuneup on it. Fresh spark plugs and wires may do more for you than a full RB exhaust on a car with worn out parts.

Next, all depends on if you like flat out power or handling more.

If you like handling, get some new springs and struts for the car. It's not ridiculously expensive, I got some Racing Beat springs and Tokico HP struts for the car for about $400 shipped to my door. If the car has some good rubber on it this will TRANSFORM the car into a completely new machine, and it will handle with the best of them.

If you prefer power, the GSLSE responds really well to intake and exhaust. Add a cold air intake (or just throw on a K&N cone filter if you are lazy), lose the stock cats and replace them with either a midpipe or high-flow cat and the car gains a HUGE amount of speed. Just keep in mind that removing the cats makes the car LOUD if you don't put a really quiet good muffler on it. If you want to go all out, you can get the Racing Beat exhaust kit, which has headers, presilencer, and muffler all together.

When I first got mine, I did intake and exhaust first, but I did have the issue that the car was producing nice power, but with the shot 20 year old suspension it couldn't put it to the ground, and I had to take it easy around corners. Much like driving an V8 boat. If I were to do it over again, I would do tuneup first, suspension second, intake/exhaust third.

After all that, then you can decide if the car is quick enough as-is, or if you want to do the little things to give it even more power.

Oh yeah, do you know what your FC your engine came from? The series 4 engines (86-88) had more power than the stock SE engine, but not quite as much torque, but overall isn't significant enough to matter. The series 5 engines (89-91) boosted the HP quite a bit. If you have a S5 engine in a GSLSE and do the supporting mods... that would be sweet.

 

ok is this worth $800?



it seems to have the EFI set up so that makes about what?

 

800 bucks for a running SE yes sir that is worth it if i lived close to you i would say its not and ask you where it was at woot...get it man gr8 cars

that car comes with a 4.10 gear and lsd you can also find rims for it caz its 4x114

just make sure the motor is still good

 

so i can put konig rewinds on there if i want, THATS SWEETNESS.

 

if they are 4x114 then yes you can....


just read up alot on the stuff you are thinking about doing

 

I'd say it's definately worth 800 bucks if it's running. Everything seems to be in pretty good shape.

That's the standard GSL-SE engine in there, if I remember correctly stock it puts out around 135 HP. It's worth noting that the SE has more torque than any other NA RX-7, so it seems much more powerful than that. Intake and exhaust can bump that up to 160 or so assuming the engine is strong. Also, GSLSE engines are among the most reliable of rotaries, so it may have 160k on the clock and still run great.

By the way...replace that Fram oil filter with something, anything else. My SE had one on it when I got it, replaced with with a cheapo Purolator and the car noticed the difference immedately. Fram filters are restrictive crap.

 

cool thanks for the tips

 

BUY IT!!!!!! just make sure the engine runs!
