Turbo N/A Adapter plates?
After reading a lot of posts where people want to convert the N/A motors to TURBO without swapping in the T2 block I started thinking.. What is stopping most people from doing this? Probably that they don't have the equiptment or knowhow to make some of the fittings needed to complete the swap.... Well tell me what you need...
I am thinking of custom producing 2.5 in spacers and intake adapers needed for this swap....
Anyone know how much thse go for? I am talking about the one for the 2.5inch spacing between the exhaust ports and the turbo manifold, and the Intake adapter so the Tb off the N/a can be used? If so Give me an idea of interest/ and pricing.. I have purchased some milling equiptment and would like to guage SERIOUS interest in 13b 6 port conversions to turbo...
Looking at 2inch piping between the manifold and the motor
and 2 inch inlet into the TB..
Help me price these products and let me know if they are even of interest to anyone..
Thanks

I'd be interested, but not at this time in my life, no job 
Most likely I'd want one eventually so if you go through with this I'd probably get one some day. Also, why a 2" inlet into the TB? Why not like 2.5" or 3"? That way if you want to have bigger piping for the intercooleryou can, but if you dont want to go that big you can always use a coupler adapter to go small to big, but with the bigger one its available for those that want/need it

Ddub.... Yeah i though about that, i guess that would make sense.. I would have to build what everyone wants, for now it'll be a custom per person order, eventually i may mass produce. I am "buying" time on the hydro CNC machine at work, and will be making SEVERAL prototypes.... That's why i am guaging the inerest on this one...so i can get to work...

I disagree... What's so difficult about an adapter plate and bolting the stock TII exhaust manifold to it? With your way you have to get the whole TII intake system (4port instead of 6) to get it to work... Not only is that a lot more money, but its illogical.

I agree that it would seem easyer but you have to consider that people are trying to cut costs by doing this swap in the first place. Buying a complete t2 manifold setup even at a junk yard won't be cheap, then add the price of the adapter and you could have swapped in a t2 motor, this option is a little cheaper and is a tried and proven option,..

I understand there you need an adapter to make the TII manifold fit the NA block but i thought it was a spacer just to make the turbo clear the LIM, am i worng? and doesn't some1 already make that piece?(RB)? Besides that what pieces would you be making? I'm not quite sure i know what you mean about the intake adapter either, would it replace the hard plastic elbow?

Yes its a spacer for the exhaust manifold to the block, as far as I know rb doesnt make one. Aaron Cake for example used 2 RB header flanges and welded them together with the correct amount of piping to space the manifold out.
It's true you could use the black plastic elbow for the intercooler still, but an adapter plate for the TB would be way better.

Ohh ok i think i've seen another write up where some1 used the rb flang too i guess i've just seen so many pics of it i thought it was a piece. But if you do make these parts i'll be interested in anything that will make it easier since i will be turbo'ing my NA this summer

why bother with adapter plates to begin with. unless i am misunderstanding something here, how dificult would it be just to make a custom manifold that positions the turbo out of the way 6 port LIM. the piston guys have been dong it for years upon years, why are we afraid to?

Duh you can make a custom manifold, but honestly could the majority of us do this? NO... I'd like to see you go out and make a custom manifold that clears the LIM, holds the turbo, and makes everything match up the way it's supposed to. I'd be surprised if you did... The only company making a custom manifold/turbo "kit" for the 2nd gen n/a rx7 is fc3s.org but they started many many months again and have had no updates in about a month or a month and a half. I'm not even sure when or if it's going to be done.

Because the adapter is the easiest part of the project? It's all the rest of the little details that take up the effort...
Really, any commercially produced TurboNA kit should be based on a custom exhaust manifold that properly clears...

Like i said this would be for people who are going to do the install like the majority of people who have built N/a turbos....do.
I am not planning on making a commercially built Turbo kit.. I was merely going to offer the two adapters needed for the install, I don't have access to casting equiptment, so a custom turbo manifold and wastegate are out of the question. I thought that making the adapters would help some people out.. And at a resonable price why wouldn't someone want a professional looking adapter for thier setup? It would save time for the home hobbiest with professional results...

Id make them on demand though. Dont spend alot of time doing a whole bunch as im not sure how many people are accually going to go through with the procedure. Sounds good though!

Yah think? Obviously any professionally produced kit will be a new manifold, but are there any out there? NO! No one has taken the time or effort (except for fc3s.org which still isn't out and they wont say if/when it will be) to make one, so we have to use spacers. If someone out there thinks they can make a completely new and "professional" manifold, well geez go for it. But honestly who on this board would/could do it?

RRTEC, thanks man this is extremely helpful to those out there wanting to do this that dont have sufficient access to welders. Keep me posted
As I said it wont be a while until I have money and am ready to do this, but if you are still making them at that time I'd be all in

I am doing this swap right now in the 85 gs i have with a 2nd gen 13b. the 85 doesnt have the same fitment issues as the 2nd gen does The specifications have to be exact 2.5 inches for the exhaust manifold or it will not fit well at all in the 2nd gen. The TB manifold could be used for the Turbo swap or the m-90 supercharger install if anyone ever attempts that....

The TB adapter could be used to attach an "aftermarket" intake to the TB as well, for those of you making cold air for your N/a's... Doing away with the ugly plastic TB inlets....

The spacer between the engine and Turbo manifold would be a great idea.
And include longer studs for the project.
I would be interested in this due to the fact I wanted to keep the stock intake manifolds. I have a 1984 GSL-SE and it was the first year for the 13B and fuel injection in a rx7. So I want to keep a somewhat original look to the car.

Well if you used a turbo LIM you would need a spacer/adapter to the 6port housing. Now If you have ever seen a stock turbo you will know that the turbo already has only about an inch clearance between it and the LIM.
So if it was spaced out due to an adapter you will then HAVE to make a spacer for the turbo.
You'll then have the UIM offset like an inch unless you get another adapter to set it correctly. That's alot of changes to put a TII LIM and UIM on which will force you to run a FMIC since the TMIC will be offset of the TII hood scoop.

Not trying to discourage, but the adapter is just a small part of the project. Anyone who is doing is project should be able to weld on up, or be resourceful enough to contract a local welder to do so.

That's true, but all I know is that the local exhaust shops around here are a rip off, and other than that I can't really think of a cheaper/equal priced place where I live that would be willing to weld that stuff up for me. I don't own a welder and my friends don't either, yet. So for now if he makes an adapter since he has access to a welder that would be cheaper than me buying the flanges/piping needed and having them welded up for me, then **** I'd go for it
BTW Aaron...
For your adapter I know you used 2 flanged from RB headers and welded the need pipe in them, right? So were you able to obtain those flanges from racing beat or did you have to find headers to cut them off from or what?
