86 mazda 626 turbo swap

someone correct me if i am wrong (and i prolly am), but isn't the 86 engine a completely different animal from an 89-92?

the main differences are the stroke, and the hydrolic lifters, oh and the carbs are a little different but other than that they are the same

An 86 626 turbo car has an 8 valve head- and it's a 2 liter motor with manual adjustable valve lash rockers. The distributor comes out of the back of the cylinder head- and will be in your firewall. The intake comes over the top of the valve cover- and it's fuel injected.

Use the bottom end of the 626 with the 2.0 liter motor and correct compression ration pistons for turbo. Use the mazda b2200 or b2000 cylinder head, use the 626 intake with fuel injection, use the turbo and exhaust manifold. Use the mazda b2200/b2000 distributor. Only thing you will have to check- if the 626 fuel injection computer and wiring harness will req a pickup from the distributor- if it will not(I don't think it does on an 86) then you can use all of the fuel injection computer/ wiring harness VAF meter and fuel pump, and have a 2.0 liter 8 valve fuel injected turbocharged mazda engine- that bolts right up to your mazda truck trans!

the distributor comes out the side in the back...the thermostat is in the rear...but i believe i can swap the front of the motor, i guess its the rotating assembley, with the front off a b2200 which will have the distributor and thermostat in the front

this is all kinda unclear so i want to know do i need a block out of a 626 and the head off my b2000 and the fi and turbo manafold and the block will bolt straight to my 5 sp trany what kinda mony and mods am i looking at

im not exactly sure yet because i havent started on the swap yet because i have been short on some cash but when i start i will take pics and keep everyone posted...but yea i think we are going to try to use the head of a b2000 because the dizzy comes out the front instead on the side and you will need all the wiring and computer from that car...we have it easy because we have a whole car!! Hope that helps...ill keep you posted when i start...my dad said something about pulling the motor maybe in a week or so...i only have like 2 weeks left of college left so i will probably start during christmas break

As already posted someplace else I'm sure:



There is all the Mazda cross-connectivity info you could want!

ok we finally pulled the motor out this past weekend and totally disassembled it...now i need to know best place to look for performance parts...i tried peaco performance but they want like $4100 to build me a stage 2 motor...me and my dad were like "WE COULD BUY A LS1 CRATE MOTOR FOR THAT MUCH!!!"

so anyways im looking to get anywhere from 150-200hp from this motor...we are going to rebuild the whole motor so what should we replace the stock internals with in order to achieve this kinda gain

are flatlander pistons good pistons? They price at $42 a piece which is fine...paeco performance wants $420 a set for the pistons they sell

and does anyone know the specs for the performance camshaft they make for the b2000 b2200?

also does anyone know and high flow fuel injectors i can use...stock or aftermarket

can i use a blowoff valve for this setup...i have heard that i need a bypass valve....i heard that the comp will think that there is air goin in the intake through the afm but there wont be air goin in the intake manifold...any info on this would be nice to know

i think that is all i wanted to ask

the best place to find out about turbo mazda motors is mx6.com the fe3 kia motor is the best to run a turbo setup and a stand alone ecu like megasquirt the f2 is what mazdas come stock with and they are non expandable motors what ever you put into them you never get out in power but then again the mazda 626 came turbo'd and they used the f2 i would say mx6.com is the place to go i looked into this awhile back and thats where i went
