Hi,

Putting parts together for next winters refresh and need some help deciding on between an Artec Stock replacement cast manifold, Hypertune Stock replacement tubular stainless manifold, or if there's any other options you'd recommend.

The parts list:
Evo V with Evo 6 engine, considering doing a rodjob with Kelford race balance shaft
Evo 9 80 series turbo with turbosmart actuator
Full 3" exhaust with true 3" downpipe
Kelford 264 cams with adjustable pullies
Plazmaman compressor outlet cast pipe
Haltech Elite 1500
Evo 9 headgasket with ARP bolts
Deatchwerks 1200cc low impedance injectors
60mm Bosch DBW throttle body

Looking to put together a responsive streetcar with around 360-380whp, stock manifold should be fine, but looking to future proof with a nice manifold that'll help make the current goals possible and make the setup as efficient as possible, looking to port the turbine housing inlet as I've read this does helps a little in overall response/efficiency.

I live in New Zealand and getting parts from USA is possible, but not easy and rarely cheaper than sourcing local or from Aus.

I've not seen any testing/results on either the Artec or the Hypertune manifolds, however all reviews I've seen says throttle response is improved with the Artec, haven't found any results on the Hypertune.

I understand on an 80 series turbo, the gains will be marginal, however future plans include a stock frame replacement turbo such as FPGreen, TF06-18K or something along those lines.b

Anyone have any first hand experience or know of any testing done etc?

Cheers
Jake

We've got a few cars over here that have the Artec manifold. Stock turbo Evo 9s in the 410-430whp range on E85 seems to be pretty normal.

One of our sponsored drivers has one on his 9 and made right around 425whp on stock turbo, stock engine with just head studs and S1 cams, Artec O2 housing, 3.5" ETS intercooler and pipes, Skunk2 inlet manifold (unnecessary), some sort of catback. He previously had a non stock frame turbo with a welded manifold and kept chasing cracks with it, zero issues with the Artec piece for the past season and a half.

 

Appreciate the feedback, Artec seems to be the preferred stock replacement manifold everywhere you go and everyone you speak to.

Good to hear some stock 9 turbos making 400+.
E85 isn't readily available anymore so I probably wouldn't go that route so I'd have to settle for sub 400, still be pretty fast from what I've read, everyone seems to rate the Evo 9 turbo to be a good upgrade for little spend.

 

It's really pretty impressive, people like to say how far turbo technology has come but these stock turbos are holding up against the best even even this day. It's amazing how much these stock evo 9 turbos can make reliably after almost 20 years. I don't think turbo tech has come very far, it hit its peak as far as engineering around 2005. Only thing is metarials that got better/efficient.

 

I'm no engineer, and reading up on it can easily become oberwelming, especially if you can't read lol, but what an Evo 9 turbo offers especially when taken cost into account, is hard to beat without spending much more and thats kinda where I'm at which is why I'm looking at ways of making the Evo 9 turbo with 264 cam combo as efficient as possible and hopefully it'll be enough. I don't know how much better you can make it, manifold is one, porting turbo and intake probably and a plazmaman cast J pipe might all do a little each, is there much else that should be looked at?
I've got a true 3" downpipe which made the biggest difference on my stock setup, 3" should be enough for the Evo9 turbo I'd say?

 

Artec makes a nice manifold. Unless you are doing Auto X or class racing the stock 9 turbo is still too small and chokes after 5000-6000rpm. An FP 18K, green or red is a much better option IMO. Those options will be online and fun by 3600-4200 and go to 7500-8000 well.

 

Yeah I'd love an 18k, however getting it to New Zealand after exchange rate, shipping and import duties, it just isn't worth it.

There are some options available in Aus which is easier to get to New Zealand, such as GTPumps and Intense Turbo.

The goal for the car is "b-road" or "touge style" mountain driving as well as track days, not really into drags

 

If you've got some Fp green/red like options that are online by 4000 or so its worth the upgrade. Sure a stock 9 turbo will make 350-410 whp depending on fuel, it just won't have a wide powerband like a good bolt on turbo. A wide powerband on these cars is fun.

 

I was keen on the Intense Turbo 5353rs and when I spoke to them they said they've got a new updated version coming out end of the year so we'll see what that looks like, I'm also considering running the stock block so a 9 turbo would be safer i suppose.

 

This is actually kind of counter intuitive. Depending on fuel and how much torque you make, the quick load up of the evo 9 turbo may actually be harder on the internals than a larger, slightly laggier setup. Torque spikes up to 400lb-ft+ is hard on the stock rods.

 

I installed the Artec manifold on my IX with stock turbo. Seems to work well spool is as good as stock or better. Only surprise is the stock heat shield can be reused but the bolts are M6 not the factory M8. They could be retapped but I did not want to do that since I had already installed the manifold before I noticed this. You may also have to modify the O2 housing to block bracket the position seem to be shifted slightly. Could also have been the non-Oem O2 housing being off.

This is easily managed with the tune.

 

thanks for the info. I'm about to purchase... there's no stock replacement o2 housing from them right?

 

No stock replacement, just their 3.5" outlet. It's just as well made as their manifold but requires a custom downpipe.

 

yeah I have to wait for the downpipe to be in stock
