hi all,
im about to do a swap and i have a few questions. before all of you bash me, i looked online and found nothing... we really need a parts review section like the miata forums!
#1. which is the best company to get an s5 13bt from?
#2. which na clutch is the best? act? competition clutch? exedy? i dont really care about pressure engagement. im building her for drift...
#3. i wanted to get the cusco lsd. which is best for me for drifting? 1.5 or 2 way?
that's about it for right now guys!
thanks, and merry christmas to all!

 

1. A Mazda dealership
2. ACT and Exedy are well known brands, it comes down to what you are doing with the car.
3. 2 Way!

 

lol thanks... well, ummm as for where to get the engine, i was meaning jdm site... so far i am thinking of ordering from tiger japanese engine... i guess ill go with the ACT? i used to have competition clutch for my miata and ACT is actually cheaper in price... another question- 4 or 6 puck?

 

website wise, you can try bestofjdm.com they have a 30 day startup guarantee and warrantee, if anything good persists let me know, but from my research, buyin a jdm motor and rotary motor at that is all a gamble. but bestofjdm has emailed me back with info with a quickness n such, so good luck to ya

 

*keeping tabs* on this thread....

My vert needs a new heart also, trying to decide if I should swap in a JDM T2, or just Plain Jane rebuild it. (while trying not to break the bank...)

 

As am I, not sure what to do with the Fc I might get, keep it for awhile and sell it for a T2 later, or just swap a Jspec S5 motor into it.

My last FC was an S4, I have no idea how the S5 swap would even work with a Jspec. Anyone Know?

 

1. Mazda Dealer, JDM dealers...not always the best though.
2. Get a flywheel and pressure plate from Racing Beat, and as for the disk Ogura Clutch is awesome for JDM...for North America go for ACT.
3. 2 Way LSD is the best choice for drifting..

 

1) Get a JDM and EXPECT for it to need to be rebuilt. Probably need at least a rotor and housing
2) Get whatever clutch you want, or are happy with.
3) 2 way.

Also, is your FC an S4 or S5? I know you said you want an S5 13bt, but it make a world of difference with ease of the swap. Also, I hope you searched enough to know that you also need:
-ECU
-AFM
-Boost sensor
-engine harness (most likely)
-boost gauge
-TII hood
-FD or better fuel pump

If you ask the naysayers, you will also need (but not required)
-TII transmission
-TII driveshaft
-TII differential with axles
all from the same generation

If you stick with the NA driveline you will need to put the NA flywheel on the TII engine. (not recommended if you are drifting)

If you want to make big power, I hope you have a big bank account to go with it. Then you can skip all the ECU, AFM, etc and get a standalone, larger turbo, FMIC, injectors, fuel pump, water/meth injection, TUNING.

It is much more involved than you might think. Let me know what happens though. Atlanta isn't that far away and I enjoy picking up failed projects at a 1/4 value.

 

As far as getting a JDM engine, ya, expect to rebuild it. Most of the engines from jdm have around
40 to 50 thousand on them, and when they say they compression check every engine before
they will ship, keep in mind that they will ship it as long as it is over 70. So your most likely to get
an engine with compression under 80 which in all reality, isnt that good...

ya, just seen that lol. Was searchin around and got bored so i posted, only to see afterward it was 2 years old...
