So last year i bought a 13b turbo miata, when i bought it the car was not running turns out there was some wiring needing to be fixed so i got that all finished. Then i took the car to a guy who know how to tune microtech ecus. He got the car starting and running great but the clutch started to slip on the dyno at 225whp and 180wtq 6PSI.

After that happen i drove the car around for a day until i heard a noise from the motor. So i call my guy up who had tuned it and he said it sounds like the rotor bearings. So i got the car home and pulled the motor out and apart. Turns out the guy who owned the car before me didnt know the right way to remove the crank pulley. So the thrust bearings dropped and ended up sending metal all over the motor. Thank fully i premix my gas so my housing are in great shape so they will be used on a build later on.

So i found a used motor that looked to have some life left in it so i took it home. I swapped over the parts needed off the old motor and got the new motor in. It started right up with a vac of -18.

Here is a list of everything i have s4 13b turbo motor, 1 gen front cover, 1gen water pump, ITB's, racing beat intake manifold, mazda trix crank pulley, RC650cc primaries, ID1000cc secondaries, custom turbo manifold, hks wastegate, HTA3582R T4 divided 1.00A/R housing, custom turbo back 2.5" exhaust, MDS blaster SS coils, Microtech LT10S with upgraded map & rpm table, Light weight flywheel, clutchmasters fx500, modified 84 NA rx7 trans with miata tail hosing to be able to use factory mounts, and Torsen swap rear diff.


Things im still working on, Bigger radiator, 86-92 turbo trans, and 3" turbo back.

My goals for the car is to make 400-500whp I plan to use it as a sunday car and track day car with a few 1/4mile trips.

Any info you guys could also give me on what i might need to reach my goals would be great.

So let me know what you guys think of the car and here are some pics. These pics show my old up pipe and downpipe, Im working on a new up pipe and 3"downpipe.

Also have a question about doing a trans swap. I want to swap my NA rx7 trans to a FC turbo trans. I want to keep my flywheel and pressure plate as i found that ACT sells a clutch disk that matches the NA flywheel but is splined for a FC turbo trans. Im worried the starter will not sit right and wont be able to turn the motor over.

 

Thats an interesting intake. What throttle bodies are you using?
Looks like alot of fun!

 

Im using the racing beat weber carb intake manifold with Extrudabody wber itb kit.

Sweet! Is that a fake MoMo steering wheel?

 

I think it is,lol it came with the car i plan on switching it out.

 

I ENVY you!!!!

I might even consider selling the FC for and start messing with the Miata (dont know if I want to start another project though...)

 

Thanks and trust me you dont want to go this rout i bought the car mostly done. The whole build was done nice but not right with some stuff. They used a NA rx7 trans thats not good for holding power, they kept the miata 1.6l rear diff thats weaker then the NA rx7 trans, the turbo back is 2.5", the clutch is a stock NA clutch, and from what i guess the injectors will not let me make the number i want.

I always wanted to do the 13b swap in a miata and now after everything i have had to go throw its not worth it to me. I would have done one of these swaps s2k, sr20, 2jz, vq35, rb25, or ls swap.

 

sweet build

 

is that the new engine in the videos ? sounds like its running on one rotor ?

 

People keep telling me that but i think it was running like that for a few reasons, my intake manifold gasket was bad plugs are need of changing. Also think i had too much premix in the gas as the car sat for 3 months.

 

This is my miata im currently building a turbo engine for it the pp is not fast enough for me lol

Very nice what trans are you running?

 

Here is another video of the first start of the new motor.

im using a gsl-se transmission

 

Nice I have a 84 rx7 trans with a miata tail housing on it so i could use the ppf.

 

nice i didnt know that the miata tail would fit but i made a custom bracket so i still have the ppf on mine

 

Yeah thats the great thing about the NA rx7 trans is there the same as the miata trans. The only have different gearing, and different tail and bell housings.

 

i'm thinking your timing is off?

after hearing it again in the video. also takes a while of cranking to start....

 

Nice!!!!

 

I am not very sure for the timing as i have a mazdatrix crank pulley. I also dont know how to lock in timing on the microtech.

 

Looks good, my buddy is wanting a miata and I keep telling him to do a 13b swap in it.

 

nice swap...Is that fabricated front engine mount or do they sell that somewhere?


Anyone interested in a 96 Fully loaded miata?
High miles but perfect for a rotary swap!!!

 

From what i know no one make a kit to swap a 13b in a miata this subframe was modded to mount the 1gen front cover mounts.

 

Another good thing is that transs fits perfectly on the stock hole so no need for cutting and the drive shaft only needs to be cut i think 3 inches and and attaches to the stock miata diff without any changes
