I am writing this in response to the multitude of post that revolve around this topic and putting it in the learners corner.
This is just to get the car running and substituting any "performance parts in place of stock

Parts list:

Halfshafts/Axels -->

From corresponding Transmission (axels from Type-F = Type-F transmission, Etc.)


Engine Wiring harness/loom -->

Turbo engine = turbo loom, N/A engine = N/A loom; BF Mazda 323 GT/GTX, Mercury Capri N/A or Turbo.


ECU -->

Turbo engine = turbo ECU, N/A engine = N/A ECU, BF Mazda 323 GT/X, Mercury Capri N/A or Turbo


Sensors -->

All the appropriate sensors for the corresponding engine.


VAF -->

Turbo engine = turbo VAF, N/A engine = N/A VAF; BF Mazda 323 GT/GTX, Mercury Capri N/A or Turbo.

Fuel Pump -->

BF Mazda 323 GT/GTX, Mercury Capri N/A or Turbo.


Exhaust -->

drive to exhaust shop and pay $300 (edit: I think you could have it done for less than that...expect to pay $150-250 (MAYBE more), depending on location).



Info:
--The above listed Transmission will BOLT UP to any B6T or B6 DOHC. Use a B6T or B6 DOHC flywheel and clutch only.
--Many parts can be substituted for performance...I.E. Turbo (VJ-16), ECU, Fuel Pump, intercooler, piping, and VAF.
--Alot of the parts can be uprated while off the car...I.E. Intake manifold, Port Polish, Pistons (higher or lower compression), Cams (More Duration or High Lift), Cam Gears.
--A good IDEA is to purchase all NEW sensors, all NEW Gaskets, New Waterpump, Hoses, Radiator, Belts NGK SparkPlugs, Wires, Distributor Cap and Rotor.
--Replacing the above listed items will minimize problems in the future. Also it is easier to do when you of the car.
--From what I am told there are a few wiring differences for looms. Do yourself a favor and pickup the Shop Manual wiring Diagram for your year car and the year of the donor Loom. Headaches, Cursing will be reduced
--If you are spending the money on the swap you can spend the extra money on the Shop manuals and parts.
--The Engine and transmission just drop into the engine may no mods required.
--FYI all Mazda BF, and Mercury capri cars have the same number of splines attached to the hub.
--Mercury capri = 10.2inch front rotors, you need these uprights/knuckes/spindels to do the VR4 Upgrade.
--Mazda BF 323 = 8.11 inch front rotors, Junk

CORKSPORT is a wealth of Information call them...



All new sensors could cost you a couple arms and legs... O2 would be a good idea.
Felpro makes decent gaskets...
Intercooler? Stock , MX6 / Probe, Starion with more trouble, custom...
Port the wastegate while the engine is out. Smooth the inside of the exhaust manifold too, port/gasket match to turbo and head.

Use a compressor bypass (diverger) valve, not a atmospheric BOV (blow off valve). The 1G DSM or WRX ones are good then comes the Bosch with the metal diaphragm. If you want even cooler sounds, for $200 the GReddy and HKS units (BOV's) are good, make it recirc to in front of the turbo. Definately ditch the stock one.

You can use a larger turbo VAF on a n/a engine. That's what the Miata (and BG?) guys do.
RX7 turbos (and the n/a ones?) have the larger VAF like on a B6T (BPT?).
VAF adapter for a RX7, Protege, or stock off a Nissan? BMW?.
fst and I have HKS n/a 80's Supra ones... tight, right

2nd and 3rd gen RX7 fuel pumps also work. Walbro makes a pump. Heard of people using Nissan pumps.
The Miata engines are the same just rwd, you could use the long block with the fwd front/valve covers, accessories, engine plate and flywheel??
Or the cams and pistons for a little more pep in a n/a motor. Only the 9:1 auto pistons in a turbo engine (Miata cams are smaller than the B6T?)
Good general B-series info here: http://members.aol.com/solomiata/MX5Engine.html

The only things Toda sells that are going to work on a B6T are the cams, adj. cam gears, and the metal head gasket.
Forget about those 11:1 compression pistons in a turbo engine...
http://www.todaracing.com/products/m...ata/index.html

HKS makes cams, cam gears, GTX exhausts, foam filter intakes, VAF adapters, the F-CON and a couple chips for it: http://www.webcamshafts.com/
I think this is the only cam that works with the stock HLA's??

More cams form the site below: Mazdaspeed (still?), Jun (not listed on their site??),Paeco (regrinds? I'd try the Webcams 1st...), and Gude (expensive? only sell complete head packages now?). http://members.aol.com/solomiata/cams.html
http://www.junauto.co.jp/products/index.html?en
http://www.paeco.com/ (these guys are a generic / "we'll tune anything" kinda place)

Here's a deal, $100 a cam gear: http://www.speedstash.com/camgears.html
http://www.mvpmotorsports.com/Templa...263&SearchYN=N

Wiseco makes a couple pistons for the dohc B6 and BP. These are what Flyin Miata sells on they're site.
And they are +$100 cheaper here: http://www.raceeng.com/mainNew.asp
These come in 10.5:1 and a much more turbo-friendly 9.0:1
Race Engineering also sells the same Cometic (semi?)-metal headgasket as FM. They're probably cheaper on that also...

ARP head and main studs for a Miata fit the B6T. Part #'s are: Head 218-4701, Main 218-5401
Try raceeng.com, Summit Racing, or Jeg's for good prices.

Mazda FWD tranny summary: http://www.fordfestiva.com/performan...modtrans04.htm
Custom halfshafts are an expensive but doable option...
Someone should dig up more info on the how the new Protege LSD fits all the fwd trannies with some mods...

Better upgrade turbo is a VJ11/14 hybrid. Spools 500rpm's quicker than stock, gives lower intake temps, and is good for 15psi up to redline...
My vote goes for this or a bb WRX (TD04) or Garrett bb T25/28 hybrid on the stock turbine housing.
VJ16 (and VJ17) was bigger all around, lagger, supports 18-20psi?

DON'T remove the boost / fuel cut unless you hae a chip/ fcon or some other means of increasing the fuel supply. Stock ecu is only mapped to 12psi, after that you run lean and can grenade your engine...

Fidanza makes a alum. flywheel and UR (unorthodox racing) makes a crank pulley. Or use a Miata crank and pulley...
ACT and Centerforce make clutches. Maybe Exedy for the fwd's?

Now some SS valves like Manley makes for the BP would be nice for the B6T.

Word, Im Back

macdaddyslomo

Phil I noticed something missing on your parts list....you forgot the igniter...It's a seperate component from the distributor on the turbo engine

JDM-P5

Now that you mention it...you're right! Yow...I'm actually going to get to use this! I'm getting an 89 323 next week...if all goes well!

slayer4u

this isn't a toyota. the B6t didn't have an ignitor.

macdaddyslomo

Neither is my MX-6 GT with F2T, or the Capri XR2 with a B6T I used to own....but they both have a seperate igniter......ALL distributer equipped cars HAVE an igniter, most just have it as part of the distributer,rather than a seperate part
