I am replacing the motor in my 89 N/A from the stock 13B to a 13B-Turbo motor. I was wondering what are some easy (and cheap) ways of getting more power from it. Its making 205 hp with the stock turbo on it, but Im sure thats to the flywheel. I was thinking about maybe putting on a new flywheel to let more power go to the wheels. Plus I am looking at a new drive shaft, so I dont have to replace my rear end. I heard someone mention a ds that would go from the turbo trans to the N/A rear end but I cant find anything about it specifically.

Any recommendations.

EDIT: I am planning on replacing the stock turbo in a few months to something better, so I want some parts that can cope with stock parts but that can also hold up to the higher horsepower to come in the future.

So many things wrong with what you just said. I hope your not doing your own conversion.

You need to search and read more please. Everything you have asked and said wrong has been covered many many many many many times before.

TII--->N/A diff driveshaft

And no real cheap and easy ways to get power. But I guess, that depends on your definition of cheap

Just whatever you do, don't go the cheap route, because you are going to be spending equal amount or more, going cheap route then you are just paying for the more expensive that would be more dependable. In a way tweak is actually telling the truth. Thats why in the FAQ it says search before you ask, if you can't find it, then ask...

Get the turbo engine in first, then see if you need more power.

Actually - Nitrous is pretty cheap and easy ........seriously.

your NA diff will not hold up long under the 13bt's power, I'm not sure about the drive shaft, but I don't think the NA drive shaft fits on the turbo parts. basically when you put a 13bt in an NA car you have to transfer the WHOLE turbo drive train; motor, trans, shaft, diff, and then you'd probably want a five lug swap as well (bigger brakes are the main reason).

Conversion driveshaft - I linked it in my first post. Mates a TII trans (regardless of what engine its bolted to N/A, TII, doesn't matter) to an N/A rear.

How long the diff lasts will depend on his driving habits. If he's doing drag launches all the time it won't last too long - but DDing it shouldn't be an issue at all.

I already have a 5 lug swap on it. And I dont want to swap the rear end now, for the simple fact that in a few months I am going to rebuild most of the parts on the car and I dont want to cheap out now on a used rear end because I am having to buy it before I planned.

All that aside, easiest way to get more power out of this car: More Boost.

Add boost and gas and you'll get more power. Get a boost controller, some bigger injectors, rewire the fuel pump, some sort of fuel controller, and someone who knows how all this stuff works, and get to a dyno.

There you go. Turn the boost up, and the power goes up. Don't waste your time on lightweight flywheels. You can also blow up that N/A rear end really quickly with only a little more power than a stock TII puts out, so you might want to think about actually sourcing a TII rear end so you can save yourself the $$$ on that driveshaft you won't need.

... get a BNR turbo, it's a direct bolt on to your tII for cheapish.... 350 or so for a stage 1.....750 for a stage 2. But If you get a bigger turbo you have to realize a few things, like the fact you are putting much more air into the system... in order to utilize this air for more power you need to add more fuel, ergo bigger injectors and/or a stand alone or piggyback AFC.

How To Get More Power:

1. More Compression

2. Increase Volumetric Efficiency

3. Light weight (drivetrain) parts

4. Quit being a dick and play nice...

Read the 2nd gen FAQ.

You don't have to read through countless threads. It has all the information you've been asking this week, which gets asked about every two days by someone who wants to do a turbo swap in their cheap n/a.

I don't really understand why these people KNOWING they want a turbo RX-7 even bother buying an n/a in the first place. Its like buying an imprezza and then asking if you can turbo it, when a perfectly good and better factory turbod car is available.

If you have the cash for a turbo engine swap you could have just bought a TII in the first place. All you have to do is be patient and one will end up for sale soon enough. But of course they don't do any research prior to buying the SE or GXL.
Then they come here and ask:

"Can I turbo my n/a?"
Everyone says "No!! n00b do a whole turbo engine swap!"
Then they guy says "What needs to be done for a turbo engine swap? Is my car going to be hella fast, foo?"
Then everyone is like "Not again! SEARCH first dumbass, this has been covered countless times!!"
Then the guy gets all mad and pissed and blah blah blah......

all motors are air pumps make a better air pump ,full exaust, intake, under drive pulleys dicth the a/c if you didn't already, get rid of emisions if you can, and if your still lacking bore out your throttle body get an ecu and port it

ummm.... for some reason my post just got deleted .... dont know why...

anyways I will repeat it ...

Its 350$ for a stock turbo rebuilt, $625 for a stage 1, and $725 for stage 2.


Sorry mike, hope I didn't hurt your feelings. :'( :'(
