While talking w/ RX7CMS last night, an idea came to mind that we should offer a 12A bolt on turbo kit. I have begun talking to our fabricator about this, and he doesn't see it as a problem as he does many turbo setups on the older Rx3s over in AU. My question would be this, what type of kit would you all look for? We might even go as extreme as a GT35/40 Bolt on kit for the FB, but we're not sure if the market is here for such a large turbo kit, so what would you all like to see, the gt35/40, a simple TO4? Let me know as we would like to get things moving. We are always trying to offer parts that nobody else does, and trust me, all of our turbo kits are very well made!





Maybe we'll offer two kits, hmmm https://www.nopistons.com/forums/pub...DIR#>/cool.png

cant go wrong with a 60-1... what would you do about the carb?



mike

Well, like I said we're still discussing this, but the carb probably wouldn't be a large problem. We would most likely work out a carb system to go with it. We just want to see what everybody is looking for, if we need to make a custom intake manifold and carb setup, then we'll do that too....we're still talking things over.

Mike has the right idea.A 60-1 would be perfect for a 12a because the cost of the kit would be lower and boosting it with a smaller turbo means less chance of you apexs flying thru the turbo.Either a 60-1 or a TO4B setup would work but the parts for the 60-1 are easier to get a hold of by some chance you need something for the turbo itself.Nice to see you guys are coming up with some new ideas Rotaryman88. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Well, its our goal to offer parts and kits that you cant get anywhere else, while keeping the customer's happy. I agree with the 60-1 as far as getting parts to go with it if needs be, but honestly a TO4B setup would be more likely to happen as we have access to those turbos...I'll keep you updated..and yes, the price will be less then our gt35/40 kits for the FC & FDs..but I'll get a better idea on price once we finalize what we're doing.

What would be the ideal setup...carb turbo? and what kind of carb would you use.

For a 12A, I'd say keep it carburetted just to keep it simple, a fairly modest system would be the ticket, something you could get around 200-250hp with for a reasonable price.



J

as far as which carb to use, it all depends on the background of who you ask. im a bug guy so when i got a carb i went with a dell. my friend opted for a holley.

i think youll be better off with which ever one is easier to tune, since the buyer will be doing most of the tunning. also, you can get holley jets and parts just about anywhere.

Well, just a little update on this. Our fabricator has already made 12A carbed turbo kits for some of his customers in AU that still utilize the carb setup, so we will most likely stick with a carb setup. What carb will it be? Well, we'll determine that a little later. We're still working on getting some GT35/40 kits out to customers right now and once they go out...we'll start more work on the FB kits..oh, and the turbo will most lilely be a TO4B setup. His numbers are usually around 250 on mild ported 12a motor...so with this, you should be able to bolt it up to a stock built motor with carb and run about 180 to 200 hp at 6psi provided your fuel, etc is up to the task. The price is yet to be determined, but it will be cheaper then a camden bolt up supercharge with roughly the same, if not more power potential....

Would that be intercooled?



And if a guy were to get such a kit with the idea of just getting started in the turbo playpen, and planning to upgrade components (bigger intercooler (or add intercooler), uprated fuelling, etc) later, how much power could such a turbo support roughly?



J

Well, the kit itself won't include an FMIC for those of you who are looking for a more cost effective route and only plan on running low PSI or for track use...



however, we already have FMIC kits for FBs because our fabricator is in AU and they have the turbo12a motor there already...so that won't be a problem. I'll get a price on everything and we'll probably offer stages later on...give me a few weeks to get pricing setup and stages made and I'll get them up on our site...



as for upgrades, those of you who know...a TO4B turbo is capable of more then 6psi...and you can always up the boost for more power...the turbo's themselves share the same manifold as many other TO4 series turbos..so the kits would be upgradable easily....

what kind of carb did you use to get 250 hp? where do you get these numbers from? on what octane fuel? https://www.nopistons.com/forums/pub...R#>/violin.gif

who's your guy over here in aus? which part of aus?

The type of carb our fab used I'm not sure of as we haven't discussed the setup recently due to delays in our other turbo kits which are higher priority right now.



I'll catch back up to everybody with this kit within the next week, we've got a lot of kits to push out within the next few days, and once that gets settled, I'll get prices, parts#, etc on the FB kits...

https://www.nopistons.com/forums/pub...DIR#>/ohmy.png My GT-X better watch out for the 12a's soon. https://www.nopistons.com/forums/pub...IR#>/blink.png

u know, just thought that if you guys are only gonna run around 6 PSI, you might not need an intercooler at all. that would lower teh price of the kit even more. Ive seen a few engines set up with out intercoolers, and they seem to run pretty well. Again, since im a bug guy, most of the old beetle turbo set ups(old as in air cooled beetles, not older turbo kits) omit the intercooler.

We have a intercooler kits for the FBs. To keep the price down on the turbo kit it self. The intercooler will more than likely be sold by it self. Running around 6psi there shouldnt be a real need for a intercooler. We still want feed back from you to decid what to include in the kit.

Yea, like Rx7cms said...the FMIC is gonna be sold separate and as there are guys out there who still like to fab there own stuff and would need just an FMIC....

How much power could you make with a turboed stock 12a at 5-6psi? Probably not much more than the stock 12at and I would imagine the set-up would be around $1200-$1500? I am just a bit skeptical about the value of the low budget low boost carb set-ups.

I will agree that our basic bolt on kit probably will not produce much more then a stock 12AT, but here are some things to consider:



*The kit is a bolt on, no need to pull your motor and swap and deal with all that

*An average do-it-yourselfer will be able to bolt on our kit

*12ATs are very low in numbers and aren't readily available to swap

*Our kits are upgradeable

*The turbos are quality garrett made and will be brand new, not an older jspec unreliable part



Trust me on the Jspec parts, even when dealing with Jspec FC and FD motor parts such as engines, turbos, etc, you can never fully rely on them to work out right. Our kits would have a warranty against cracking of the manifold, turbo failure and line corrosion.



It really is up to the buyer how they want to go about it, you want to do the motor swap..thats cool, if not, we've got what you want. Chances are once we finish the pricing, the kits starting price won't be much over 2K...

you still havent answered any of my questions!!! https://www.nopistons.com/forums/pub...>/rolleyes.gif

Those numbers are from our fabricator. he hasnt got back to us yet on the details of his numbers

what is the actual HP number on a 12at?



-greg

Which questions didn't I answer? I responded about the carb setup used for 250HP...it's a few posts up, the fabricator used a custom setup with a carb in AU, and as I said before I don't know the make of the carb because we haven't discussed which kind he uses, but I will get that information for you when we start making the kits for our shop. The octane level he used was standard pump 94 I believe.

I want to suggest making a kit for the GSL-SE 13b, i'm pretty sure that would be a big hit

heh heh



just wanted to see what progress there had been



and yes, as a current GSL-SE owner, a GSL-SE kit would be a Good Thing
