didnt get much of an answer on the freshalloy.com forced induction forum, so i decided to come here...

just a little introduction since im new to the forums..
im originally from honda-tech.com. i've worked on evos, supras, and numerous b-series honda motors all boost dependent. my last car was a 92 civic hatchback that had a B18b motor and was boosted with a t3/t04e. squeezed 300hp out of the motor reliably on stock block. all work was done by me. the car was good for 11seconds on slicks but it got stolen, hence the new 350z in my driveway. im looking forward to building a pretty badass street car, so look out for me.

now for the question..
does anyone have pics of their turbo manifold...im curious as to the design considering the placement of the exhaust ports on each side.

and does anyone know if geoff from full-race is developing one?

 

Whats up man. I was from HT also. (ITR206)

Doubt Geoff is making one. Prob not a huge market for one.
Also I havent seen any Z's going single that I can recall. I might have seen 1-2 posts possibly, but nothing very common from what I have seen.

 

Welcome. The forced-induction forum is the place to check.

 

single turbo kits incorporate the OEM manifolds. They use Y-pipes and crossover piping to merge the two banks into a single feed for the turbo. There really isn't much of a reason to run a specific "turbo manifold" for a single turbo

 

they dont all use oem manifolds. it is possible use after market

 

nice! another honda-tech member. are you also on the fabrication forum? it amazing to see what everybody makes over there from scratch. PLEASE START THE TREND HERE

?? maybe create something like this but keep the power steering and a/c??? or maybe making a single turbo version (manifolds routed towards the front)

 

Fabricating a single turbo T4 flanged manifold for the Z somehow would be a great venture for a fab company!! That's probably the biggest bump on the road in terms of putting together a turbo setup for the Z. I was thinking something similar to the turbonetics kit placement would be a good idea. Clearance could also be enlarged by cutting some material from the composite fiber front member or fabbing/selling a thinner one would be ideal too.

Other than that routing a cold pipe from the turbo, to the intercooler, to the throttle doesn't take much science behind it. This would definately open doors for the VQ engine IMO. If I had the capital and willpower i would definately consider this as a business opportunity!

I love the welding forum on HT. Some of those guys have some skill and could def. get some dough in their own pockets..

 

The HKS ST actually has its own manifold I thought?

 

I am sure you are aware of the space constraints, especially if you are wanting to keep all of the accessories. Our GT42r kit was able to keep everything, but involved some custom pieces up front. We used aftermarket manifolds which were modified and joined. Our GT47r kit has custom manifolds which are routed forward and then merged at the turbine inlet.

Unless you are looking for 800+ hp or just want a project, there are some good manifolds/kits on the market already that won't require the fab.

We stopped by Full Race a couple weeks ago to pick up a twin-scroll T6 manifold for our Supra and inquired about VQ manifolds. We were told they have no plans for them.

 

do you think a gt4094r could fit without a new radiator?

 

thanks guys for all the quick responses and the warm welcomes. i wasnt aware of the honda-tech presence here on this board. glad to see some of you guys playing on the RWD side.

yea..by the looks of the motor, it seems as though this car was truly made for some twins.

the reason for my inquiry was due to the fact that the turbo kits out now are rated around 800hp. i dont want that much power. obviously i can have much lower if i wanted to, but the excess lag would be unnecessary. i wanted to piece together a turbo kit in hopes of tailoring it to my own personal needs and goals.

Hal, do you know where i can find these manifolds that you speak of?

 

They were custom made in house.

 

...but OEM IS best considering the added heat energy from the turbo.

 

Don't think this was really what you were talking about but here it is anyway...

 

Just wondering why TN went with placing the turbo on that side... due to MAF sensor location and the coolant/washer fluid tanks on the other side?

I'm interested in either twin turbo manifolds or single turbo manifolds, obviously ST being the cheaper route overall... most places won't part out with just the manifolds, and if they do they charge approx. $1000+

 

why do you need a specific "turbo" manifold? The twins need them for fitment reasons, but really a manifold is a manifold - yes I understand some flow better than others. If you are running a single turbo, the oem manifolds will do just fine. Just need to route the two banks into one. Both APS and TN found two different ways to do so

 

Then how about cats? Does the TN kit eliminate cats?

 

yes, as does the aps kit.
