I was wondering if anyone had first hand experience with this manifold and turbo combination?

Application: Rx-7 FD

These folks make some high quality manifolds:

Uncle Hungry, a customer we built a motor for, is running this setup with dual 38mm Tial gates dumped to atmosphere. The motor is still on breakin, I'm sure he'll chime in here

 

just plain sexy.

 

They are very popular and known for good quality in the S2000/NSX community. Havent heard anyone using one on an FD, but I would think it should be a quality piece.

 

If I were on the market for a manifold, I'd be interesting in knowing:
- type of metal used in tubing (i.e. 304, 321 etc)
- thickness of tubing
- type of metal used on flanges
- thickness of flanges
- underhood fitment and interference with other underhood parts
- warranty

 

Alberto, re: the fitment, it's a very compact design and the WG's have to be dumped to atmosphere (vs re-route to the downpipe) so that isn't a problem at all.

 

NIce to see that there are still manufacturing parts for our FDs. I have see there kits for other vehicles and the quality of their build is very nice. Nice to see that we still have some supports from manufactures!!!

 

I'm looking forward to hearing reviews.

Who's Hungry? =P

 

do you really need dual wastegates for a GT35? seems to add extra cost. and what if you get tired of an open wastegate dump? I know I did after a couple thousand miles. I'm not knocking the quality of the piece, I'm just questioning if that exact manifold will fit your needs over the long haul. Not having the option (again, OPTION) of recirculating the wastegate is a huge drawback IMO.

I run a single Tial 44 on my T04R (bigger on turbine and compressor than GT35) with a stainless long runner Feed manifold. With the 13psi spring I haven't had boost creep issues so far.

 

^^You're correct on all counts. On my FD I run a single 44mm TiAL gate routed back to my 4 inch downpipe. Supposedly the dual 38s lead to better boost response. I have been in some Gotham cars back in the day that spooled very quickly with a similar setup.

They constructed it that way for simplicity and fitment, I guess they don't care about the hearing of the occupants

 

When I spoke to Fullrace they recommended a dual 44mm setup. Can you recall how tight the fitment was with the dual 38mm?

 

i thought we liked our WG fitment like we like our women? no? jk jk. so anyway...im in the market for a manifold and have been a fan of full-race's craftsmanship for years. im sure they could make a RHD friendly manifold if the request was made. however, does anyone know if the manifold pictured above and on their site will have fitment issues or not with a RHD FD? thanks.

 

Looks expensive. What is the price point?

 

That's a question for Full Race to answer. T
shoot them an inquiry.

Price is listed on their website... Not to mention that I even provided the link in the first post.

 

Hey guys, yeah I have that manifold. As a matter of fact, that's my manifold in the picture. The fitment is beautiful. The turbo sits way higher than the A-Spec kits making it a bit easier to work on, it also makes for smoother runner angles into the collector. The primaries are a bit larger than A-Specs also, so expect it to spool a few rpm later but make power a bit longer.

I have dual 44's on it as of now. Geoff " the engineer who owns Full-Race" is very big on twin gates on twin scroll setups. He's got tons of real world testing experience to back up his claims. You guys are right about one thing though, he doesn't give a **** about your ears lol, but there's nothing saying you can't route your dump tubes into the dp.

The craftsmanship is phenominal and if you're asking me if I think you should pick one up.........Absolutely!

 

I have twin 44's. The front gate comes out between where the rubber heater hose normally goes. The rear gate is laying horizontally just under the dp.

 

Thanks for the review Uncle Hungry!

Did you reroute your heater line or dispose of the unit?

Also was this with their GT3582R (T4) turbo? At what rpm do you notice the turbo spooling? You've had experiences with both Aspec and Full Race?

If you have some installed pics, it would be most appreciated!

 

It's a t4 1.06 gt3582r. You know what, I have to check for sure at what rpm I'm spooling by. I wanna say 13psi at around 3800. I do however have a pretty aggressive port and overlap in comparison to most ( As Rich can attest to), so an average port with less overlap might spool a bit sooner. I just extended the heater hose to go around the gate. Removing it would leave the front rotor completely unregulated as this is a true twin scroll design. I've handled both and took a ride in an A-Spec car, but never driven one. I can tell you for sure though that the FR manifold is much easier to work on.

 

Wow... that is a great looking manifold. And I do like how it sits a bit higher than my A-Spec mani...

 

Just to clarify, the pics on the original post are two different manifolds. This is a FD


This is a FC

 

Thanks Uncle!

I'm going to put an order through in the next month or so. Your input is greatly appreciated!

 

These ar looking great! How much money are u going to put up for one?

 

im really leaning towards purchasing a full-race manifold. however, i was wondering if anyone has any real world experience comparing v-band flange manifolds vs twin-scroll (divided housing) manifolds?

 

You wont have to do much searching to find out why Twin scroll systems are better. If you have your heart set on a vband you could contact Full-Race and see if they'd make you a mani with it.

 

I totally understand the reasoning and rationale as to why a twin-scroll setup would be better. I was just curious as to if the v-band setups were similar from a performance stand point, being that the v-band flange on the hotside "seems" smaller than a conventional flange. As a result, ramping up the velocity of the exhaust gas. Just wanted to double check before I went ahead and made the purchase.
