If you were going to build an NC turbo...
 
What would you build? Not a -skys the limit budget- Say 3-4k


Anyone want to make me a fudging manifold?

Splitime 09-09-2008 08:10 PM

I'll only offer ideas if you swear off stripes and teeth. :p

talusfan 09-09-2008 08:16 PM

Thats ok I'm painting them on next time, And i'll put even more teeth on just for you like a real shark 27 rows of teeth. Who needs room, IC's are over rated anyway.

Fireindc 09-09-2008 08:22 PM

Gt28 turbo.. Exede, Custom manifold, custom IC setup, ???? = profit?!

Ben 09-09-2008 08:23 PM

What are you going to do about engine management?

I don't see $3k going anywhere. Get some sway bars and put the rest in a Roth.

kotomile 09-09-2008 08:26 PM

Sounds like it'll all be custom. Who makes flanges? What other engines' flanges could be used (other Mazdas/Fords?) to prototype a manifold?

How much downtime can you afford?

Isn't HKS (or maybe Blitz, can't remember) working on something?

Arkmage 09-09-2008 08:30 PM

I'm pretty sure I could do it pretty well for $4K including a new turbo and Xede.

I'd likely run the following and do the fab work myself:
GT3071R ($1250 new?)
Homemade ceramic coated mild steel manifold (~$250)
3" home-made exhaust (pyper metal core cat, magnaflow muffler) (~$450)
Biggest IC I could fit (like $150ish on ebay)
Xede ($1,200)
550cc Injectors ($350)
Clutch (don't know what's out there for NC, guessing around $450)
IC Piping ($250 including couplers and t-bolts from siliconintakes)
Reasonable used BOV ($150)

So, minus my time that adds up to ~$4,500... of course a used turbo and injectors would get that below your $4K goal.

*edit* xede for NC is only $900

isn't this the right time for a remote turbo? that's how BEGI did it for their prototype, I think there's a lot of stuff in the way on the exhaust side.

Fireindc 09-09-2008 09:13 PM

Apparently all the turbo stuffs will fit with a battery relocation kit.

cjernigan 09-09-2008 09:30 PM

The MX5's that race in Koni Challenge with us are fast man. I'd throw some sick cams in it and leave it be. Talk to Freedom Motorsports if you want more info on that.

Arkmage 09-09-2008 10:27 PM

I would personally remote mount the battery to open up space... I still don't like the idea of a remote mount turbo...

Saving money is over rated. I want to die happy not rich.

Granted, I do not know much about which turbo is better for what application. So about making me a manifold.....
Down time is not a big deal, it's not a dd. I have to do some repairs to the beyatch anyway for a couple weeks. So while the front clip is off...

Get an exhaust gasket and send it off to some company that makes flanges. They'll send you a flange to start building a manifold. Weir Technologies offers said services, but I would NOT recommend them if timely has ANYTHING to do with with your build. So find someone besides them and get a flange made. If you can't fab a manifold buy the flanges and stock and take it to a fabricator and cut him a check.

Good idea, I Should have thought of that already. I'll be picking one up this week.

What other options, do you guys recommend for a turbo? Making power early is more preferable to me over max top end, If that makes any sense.

patsmx5 09-09-2008 11:11 PM

the GT2560 is the universally accepted turbo here for good everything without sacrificing anything. There ya go. If you don't "conform" to use it, then you should maybe mention some of the goals of the setup, and which are more important than others. Seeing how you can't have everything, the GT2560 seems to be the compromise of options most here accept. That said, I'm getting a GT32. :)

naarleven 09-09-2008 11:16 PM

I'd say with a 2.0 get a 2860RS or 2871. Preferred turbos for other 2.0's.

edit: Good move on the Turbo NC. If I had the money, I'd own the NC. I love that car. I think its one of the most attractive cars on the road.

If something is done about the stock ricer taillights....I'll almost agree.

talusfan 09-09-2008 11:42 PM

At 9k for an 08 with 2k miles, I can live with the tail lights even if they are kind of pimpish.

JDMAflac 09-09-2008 11:59 PM

9k?! Thats a helluva deal! You can purchase red film covers for the tail lights if you wanted.

Educate me, What is the difference between 2860RS - 2871 - GT2560

As far as goals, other than actually completeing it, I would like more power in the low end of things.
