GT35 for the FC
 
I have heard that A-Spec is working on an FC GT35R kit. Does anyone know for sure if there is any truth to this?? Thanks in advance.

Zach

Zero R 05-02-05 02:06 PM

Yes there is truth I should start having them available in a week or so.

Hmmmm, will this come with the tasty T4 divided turbine? If it does..... that means you'll be producing T4 divided manifolds for the FC then also. Make it equal length, extend straight from the ports at least 2 3/4" before any turns/bends, and have the wastegate runners equal length and come off at an angle in direction of flow and close to the turbine flange, and have main runner length around 13" and save me the trouble of finishing and welding mine up :D

ohh, and 2" ID main runner DIA

BoostedRex 05-02-05 04:23 PM

Sean, please post in here when they become available. I'm hoping that you'll have both the T3 and T4 footprints available? One last thing, do you have any rough estimates of price yet??

Shhhh!!!! I'm trying to learn something.

Carl Byck 05-03-05 08:41 PM

Sean, is it not cost effective to build such a manifold? I know you know what the optimum designs are, curious as to whether you disagree, or if there is a business reason to build them differently? Seems a manifold like CARX7s would be easy for you to duplicate, it onl;y has about six welds, Alternately the one mentioned above. What are your thoughts other than the Shhh???

Zero R 05-03-05 09:39 PM

Carl the manifold is being built. If I could tell you what effects it most it is finding the time. With that said my "Shhh" comment is simply there because I already know no matter how I build it one of the internet super heroes will come on and dispute about how flawed the design is. Or how they can build them for "$2 dollars using tinfoil and molecular glue so buy from me instead." I know I sound crass but I guess you'd have to be in my shoes to get it. I will get the kit done, it will be quality that I will stand behind. So no worries to all you FC guys.

Carl Byck 05-03-05 10:39 PM

Perhaps the internet super heros have something worthwhile to add... I have been a buyer for a retail chain for 18 years I know what your shoes feel like;) I really think it was a question, and a request, not second guessing your design, since yours is not posted. I remember the redesign of the FD manifolds, and or the second iteration, Mike, and I are just mentioning our wish list, which happens to be essentially identical(go figure). I realize that business demands what you build be profitable, I think posting what many people want is reasonable. The Enryu manifold is already out there, and Mike's suggestions are for a manifold one step better, I see no problem with that. Since you are in the early stages, it makes sense for people to speak up now, rather than second guess you later don't you think? Let me just say, that I appreciate your efforts, and only seek to give valuable input from "the field" as to what people may want. Anyway, I am sure it will work very well, whatever design you decide on. Thanks for supporting the insolvent FC owners of the world. Regards, Carl

That may explain why I didn't get a response when I posted this question about 2 weeks ago. :)...I'm glad to hear an update on this as other FC owners are too, I'm sure.

Zero R 05-04-05 12:41 AM

I wasn't really taking it as someone second guessing me.(Mike) I was kinda being silly at first. I'm pretty sure most have noticed I'm not quite so "friendly" anymore so If I come off edgy sorry. It's just "the field" has changed considerably it is why I believe the more knowledgeable people don't post as much anymore. The manifold will be equal length. It will be longer than 13" primaries, may be 2" maybe less. I'm just debating where/how the wastegate will be run, and what footprint for the turbo.

Brunette 05-04-05 08:48 AM

Good Job Sean!! You're the best! :)

RacerXtreme7 05-04-05 09:36 AM

As Carl said, it was a simple request so I don't have to actually learn to TIG weld..LOL although I just did purchace a TIG. It was wishful thinking on my part and am not a internet hero who will come in behind anyones work (especially anyone I respect and for that matter ANYONE who supports the FC) and say "I could build that for $200" enen though I can, as an almost engineer and machinist I know the work involved and have no problems paying (I'd pay $700) for a well DESIGNED manifold not just a well fabricated one. All the manifolds I've seen for the FC have flaws in there designs somewere and I understand cost of manufacturing must be taken into account.

I've gotten a bit "edgy" too in recent times in some post though my post count are rivaled by most experianced people in here, because of ignorance from peoples post and just in general "rice and fast and furious" attitudes. It used to be a bunch of knowledgable guys concentraiting on mechanical know how and sharing one anothers findings instead of the current "were can I find Lambo doors" or "how do I make my car run 6's". Not to affend anyone *sorry*. I guess its because our cars have gotten so cheap (due to age) and the majority of the people who can afford them now are younger/less experianced/more centered around looks then performance. But I for one will PAY for well engineered and well build parts, and yes I own a FC..LOL.

OK, my rant is over..

for now

~Mike............

BoostedRex 05-04-05 10:22 AM

Sean, please make manifolds to support either of the footprints. The regular 35R would be better suited for the needs of an AutoX or drift person like me. :D However, I can see the appeal to the T4 footprint for those wanting a bit more top end.

Zach

Zero R 05-04-05 01:36 PM

Mike, take no offense here but you cannot build a manifold for $200, and this is my point. People (not you directly) who wish to say these things without thinking it through fully only show their complete lack of experience in doing it. We'll go on a small example. You want your Base flange made. You only want one of course and it can't be a RB one it needs to be better or Mikes. Without the typical "my dad owns a machine shop" or any other type of help. Go get one made. Please keep track of all you time involved in doing so. ie redesigning it's appearence time finding someone to do it or get quotes etc. Please I do not want to hear cost off the flange only or material only. (This is where the arguement falls short.) Now please spend the time designing your manifold. If "you" do this by CAD make sure you charge yourself for your comp time. If you do this by brain power in the back of your shop. Add shop time instead. Don't forget it also needs to be test fit on the actual car. We'll give you the standard T-3 flange ordered from anywhere. We'll also give you the wastegate flanges ordered from anywhere. Now add your Fab time(to be charged as shop time) this would include anytime spent on saws, welders, Drills, surface grinders, rotary bits etc. Oh and lets not forget any shipping/tax charges accrued on flanges or material. Care to bet your over $200. Lets say you got all your stuff for free material wise. Now lets say in a mere 4hrs you were able to actually "design" cut weld and finish your manifold. We'll give you a cheap labor rate of 60hr. I think were already over budget. This is my point it is comparing apples to oranges when you do not include TIME spent. Yes your time is free when you do yours. My TIME is not. I constantly feel like I have to defend my pricing because this forgetting to add TIME in to the equation. I am not harping on you directly so please take no offense. If someone can build me a nice quality manifold for $200 I'll buy from you, I'll pay you $300 for it. That's a 50% markup for you. I bet you still lose money.This is without even including the cost time designing and fabbing of the Fixtures to reproduce. Let's forget about the quantity arguement as well. We are not building thousands or even hundreds of these. So your costs going down are minimal. Hope I didn't piss anyone off.

Carl Byck 05-04-05 02:29 PM

Sean, points well taken. I REALLY feel that a T4 footprint would be the best choice. Consider that if you choose you could sell the manifolds seperately at a later date. Also, if you use a T66 as your model, as you know you can fit pretty much any thing else. What do you think of the Enryu performance approach to the WG runners? Ie the 1/4 cut piece of tubing used to improve the angle of incidence to the main flow? That is what caught nmy eye about that manifold. Thanks for listening, and sharing your expertise, Carl

Zero R 05-04-05 04:15 PM

I think your looking at that manifold wrong, that is just a peice of bracing unless they chose to not fully weld it up ;) We'll see what i come up with, I'm sure it wont make everyone happy but it will be more than enough for the application 99% of the time.

BoostedRex 05-05-05 10:26 AM

I'll be keeping my fingers crossed for a regular 35R manifold(T3 hotside). And I'm very sure that most everybody else is going to be crossing their fingers for the T4. Either way, I'm sure that whatever comes out of A-Spec will be top quality and will work great on the FC.

any updates on when the kit will be on sale? Very interested please keep us updated Zero. Thankyou

BoostedRex 05-18-05 05:37 PM

Sean,

Are there any updates from A-Spec yet? I'm still waiting to hear about what's coming down the pike so to speak. Keep us updated when you get a chance. Thanks again.

Zach

Zero R 05-22-05 04:41 PM

Ok finally got the car here to test fit with. It will most likely run the T4 flange to start, but no worries Zach, I think we can get around you needing the T3.

igottafc 05-25-05 07:49 PM

im curious. i lack some knowlege when it comes to turbo's. With a T3 flange that means its a smaller turbiine house which equals quicker spool? also what does the devided housing mean? Im extremely interested in this kit. Im looking for a extremly quick spooling setup. Will this kit fullfill that? thanks -alex (sorry to go a little offtopic)

kd86rx7 06-06-05 04:37 AM

is the kit out yet?
