My guess is the Microtech is set up for the FD.

I'm curious to find out if that's true. It would seem that with as much port area *** the Renesis has, eliminating the progressive manifold would be worse then wiring the VDI and aux ports on the older 13B. As a daily drive it seems odd that all the optimization Mazda has done to give the engine a decent midrange gets thrown away for a system that is essentially designed for race only and only makes power over a narrow range.

well, im actually unsure to how much low end will be present. but im sure it will be plenty enough. maybe not as much as a factory rx8 with the stock manifolds. but the lighter weight of the car will make up for that.
also, even BP 12a's with down draft webbers (wich are pretty much ITB's) are driven on the street daily. and thats supposed to be a all top end set-up.

now if they can produce enough spark to handle 500 and 600 horsepower turbo 13b-rews. they will be just fine to handle the stock internally reni. and the stock reni coils are the weakest of all. so its still an upgrade. and i just might throw a 6a on there. not sure yet.

To the OP, good luck and kudos for taking on the project by yourself i wish i was that handy and had that much time.. It's funny cuz alot of the guys i know down here are swapping their Reni's out for 13b's or rebuilding with Turbo II Rotors to go turbo.

good luck man...why go through all this trouble just to get less than 240 horses. why not go turbo, i know the renesis has high compression but it can be done with great tuning maybe 8psi???

its about time...suprised i got this question so late in the posts...lol
put it this way. a stock TII has 198 flywheel. a stock 4-port reni has the same. a 6 port reni has 236 i think.
thats equal or more power from an NA reni than a turbo II. with better gas milage. less emissions. better throttle response. far better chances on reliability. pretty much, its better in everyway. its not always about having the most power. if i wind up getting 230WHP. i could spank a evenly weighted FC with 300. no lag buddy. its been proven that NA is better if you can just make enough power. look a the V8 guys stomping on turbo people.
plus, i have 2 other TII's. one with over 400. and the other should be over 500, closer to 600. its get old...
i could go on with this much much more. but i wanted to keep this discussion out of this. its a build thread. and i have seen how these debates can drag on here. now that gets REAL old... so if you would like to discuss this choice of mine (PM me and keep it out of here)

you don't have to justify reasons to put a Renesis in an FC. It's inherently cool 
I've toyed with plugging a reni in a fd. bring the cost in under 10k, no a/c no p/s no nothing, just 225-250hp in a light, reliable fd with good gas mileage. "reliable" and "fd" don't get used in the same sentance much

WTF is a Piston?..Anyone?
i also have subscribed to this thread. for your first time making engine mounts that was one good job! also the bracket for the coils looks really neat. keep up the good work i am eagerly waiting to see this thing done.

Oh i see...good valid point. a 13 second NA daily would be awesome!!! I know the old 13b in NA form can easily go over 200k with excellent care so maybe with a more advanced design it will take care of you for 10+ years

Yeah, my friend has a '04 auto rx7 and she had to get her motor changed too, they said nothing was wrong with but build up in the motor because she wasnt running it hard enough to free it up =]
so now she drives it like she stole it. still slow as ballz though.

Banned. I got OWNED!!!
yes, the FD coils have been known to be inferior to FC coils. but my choice for them is pretty simple. i had them sitting there. so convienence plays a part. and they are more compact and use only one ignitor. so its also an asthetic thing.
now if they can produce enough spark to handle 500 and 600 horsepower turbo 13b-rews. they will be just fine to handle the stock internally reni. and the stock reni coils are the weakest of all. so its still an upgrade. and i just might throw a 6a on there. not sure yet.

Are you speaking from experience or out of your *** again?
I see nothing wrong with those mounts. I think they look great and are well done. Is that all TIG welded?
I agree, the mounts look great. Well done

thanks for the comments on the mounts. and yes they are fully TIG welded.
about the coils. no one disputes them to be better than FC coils, and nothing has been proven or disproven about the reni coils. but the FD coils are not "bad". they are just not better than FC coils. but for my NA application with no PP, or bridge. they should be more than enough. especially if i add a 6a. or a few of them. they have been ran on FD motors well into the 9k rpm range of the renesis. and in PR, they still run 1st gen dizzys on boosted motors running 10's. FD coils > 1st gen set up
so my choice of coils are not that important to me. they will do the job. and do it well. and i think they will look the best when completed.
