i have a TD05 Big16 turbo and my Manifold has heat cracks in it. i dont know what kind it is but i am losing power and it is quite noisy.its time to replace it. and without breaking the bank my car has been sitting for a while and ready to get my car running. i lack a few things like putting on my PNP MegaSquirt i had made 4 years ago by Braineack. and cant seem to get it to communicate with anything. Me and fellow turbo Miata Engineer friend last year tried and he has a hydra with no problems, i REALLY REALLY want this to work.and any help would be appreciated. anyway would this Manifold work on my car?? i tried to attatch its from ebay and its a cast iron Mani.. seems legit but will it work?

 

With a t3 to eclipse td05 adapter it could work......as long as it the turbo doesn't hit the hood.

Is this the listing? Cast Iron Mazda Mitata NA 1 6L T3 T4 Turbo Manifold Exhaust 35 WG Keep AC PW | eBay

If so, your turbo will not bolt directly to that if it is a Mitsubishi-flanged hotside (which is likely given your description).

 

oh man..YESSSSSS. i really want this to work and have been doing some research on this but hopefully it wont hit my hood..any other suggestions i have been reading threads on this and i almost bought the CX racing glad i didnt..Megan racing has a combo pipe and Manifold still wondering about that one..any suggestions?

 

Do you have a megasquirt installed yet? How about a wideband O2 sensor? If those are done, stop screwing around with your ghetto setup and do things right. 1.8 swap to start. Then turbo correctly after that.

 

What Lars said.

What about the downpipe? it is most unlikely the current one will fit with the t3+ td05 adapter set up.
Either way you are getting into custom fabrication...

You could get another short life ebay manifold?
It would be better to make a proper replacement.

i cant get the Megasquirt to communicate with my computer at all i downloaded the software i dont know if thats the problem or what..nothing. WB02 sensor working maybe i should do the 1.8 upgrade..everything is on car and running i am running a little rich i am very close..its been just so hard to finish and am having other little problems..going to get it..my mechanic friend that was a miata enthusiast helped me from the start its now been my project. i have alot on the car. Torzen, FM radiator, Hardtop, Comp Motor mounts, Exedy Clutch, Etc Etc

 

Enlighten me Lars!

 

my car has been sitting up unfinished for a coupla years..its almost heartbreaking seeing the moola i have put in this car. i have no garage to work on it..i can on weekends. i am about to take it over to my Ex brother inlaws and start slammin wrenches. he is a mechanical engineer and has built many a vehicles he has built stock cars and he is into big trucks like old blazers and ****...

 

so this is the only thing that will fit my current set-up? this is getting complicated as hell. unless i change my turbo to a different setup and manifold ,these parts are not interchangeable at all different mounting brackets etc etc. i am very limited to what i can do at this point correct?

 

yes. this is why we tell everyone not to build a setup around a turbo

 

^This.

Now you can repeat it to noobs when they ask in the future.
