since you have so much meat in there, you should measure the ID of the exhaust port and match it to the manifold. the 13B housing is like a 48mm outlet and the RB header pipe is only 43mm, so making that mate up better is a good thing!

 

yes thanks for pointing that out... i put a huge weld on there to make sure it doesn't leak... also i did grind them down so there is a smoother transition... I didn't want to go too far though since i might risk cutting past the weld and defeat the purpose... i know this is not recommended but i felt like it deserved a try.... seems to be good so far...

 

and BTW it is not a RB header pipe... its a custom made 12a turbo manifold... very nice one from Turblown... too bad i had to modify it...

 

waiting for funds...

 

Aren't we all?

 

started working on it again... old motor out.... most of the corner seals were broken.... front and rear iron were cracked in the oil passages on the top drivers side of the engine... thats were it was spraying oil from when it blew up... i think i had a boost spike...boom..... got the 13b all cleaned up... 12a front cover. put new counter weights on it front and rear to make sure they matched the engine internals... took out the old pilot bearing... completely shot! waiting for gaskets from mazda trix....

 

13b together fully. mated to t2 trans again... pics to follow...

 

Here it is... 13b street ported engine.. t2 trans... act clutch 12a front cover modified for turbo drain... both oil pressure valves increased pressure modification. Still have the same modified t2 into FB trans mount and just had to bend the 12a front engine crossmember to get it to line up with the motor mounts...

We get it. You have a new beautiful Turbo FB. Congrats.

Heading home tomorrow night to work on it some more...
got some injectors from Elliot and now probably an E6k!!! i'm excited... Allmost there...

 

Did some more welding to fill imperfections inside my manifold... dont want any sharp edges to create hotspots... now the die grinding for days..... contemplating putting in FD oil pressure regulators vs my crushed and shimmed FB ones....

 

Manifold and exhaust on. drive shaft on. fuel lines replaced to high pressure with injections clamps. oil passages and coolant passages that would be used on second gen but not first gen blocked or plugged. egt bungs plugged ( for now) CAS in. radiator and fan on. 3rd gen alt on with dual pulley (took some finaggling and what not...10 ga wires ran for fuel pump with 40 amp relay and 30 amp fuse. need to solder connections and finish. throttle body is at the machine shop getting milled down so it can fit the IDs. waiting on AEM smart coils from Turblown as well as e6k..... get a great deal from Elliot... hope to get fuel pump wiring done this weekend and maybe replace belts to shorter ones so i dont hit the hood. had to cut heater hard line and splice in hose so i wasnt rubbing turbo housing. also hope to get fuel system semi complete including areomotive regulator... then wait for TB and Injectors... also maybe get my HIDs installed.

 

also got a parts car for $290. it runs but need fuel poured in it... carb needs rebuilt. just going to strip it anyways... Pics of most to follow

 

ok here is the current status... throttle body is milled and injectors fit great.. had to be milled and bored... need longer throttle cable now since TB will be 180 from what i thought..... Here are a few more pics...

Looking very nice! Keep it up!

 

thanks! Fuel system complete... have a leak.... need to get fuel resistant thread sealant and re do npt fittings on FPR.... then onto the next step... throttle cable and then ecu!!!! this might be a chore!

 

And before i get flamed.... I know its rubber hose.... However it is HIGH pressure fuel injection line with all flared tubing ends and with Fuel injection hose clamps... it will be replaced next year with pushlock or ss an hose...

 

love this build more and more with each pic. i only hope mine will be as sick when im finished with my own build
