Top Mount Twin Turbo Setup

[Kirk]

HKS has kits, Greddy has kits, or get one custom made.

I thought I checked their sites and came up empty. I'll check again. Thanks.

Ok, I can't seem to find anything. Is it possible to take the stockers and turn them up? Anyone?

[Velders]

I would try XS engineering, they run top mount twins on their track GTR

Your looking at a lot of extra work to just have the look uf top mounted twins with the 2860's. The clocking of the compressor housing will be wrong. You'll have to build custom intake and charge piping as the stock stuff will be in the wrong places, and being flanged connections, makes it a little harder.

Main reasoning, room. Side benefit, temps.

Ditto...Top Mount has nothing to do with performance, just looks and ease of access (but requires more custom work to initially setup).

What matters performance-wise is HOT manifold (ceramic coating = ), cool compressor (good intercooling), cool exhaust dump (large down pipes).

With coating your manifolds, if they are stock cast ones, should be ok, but if you have tube ones, make sure they are OK to be coated, as coming from the Subaru world, Ive suffered loads of cracked manifolds, some times the thickness of the steel used in the pipes is too thin and causes cracking. The Tomei tubes are 2.5MM which is pretty good, since most use 2mm i think, then again you can get custom made ones too.

Anyway i think majority of the questions were answered already. Good luck with whatever route you choose

Gotta be honest here. My hmmm...pretty much only reason to top mount the turbos is for the appearance. I will only be putting GT2860R-5's in there which fit in the stock location, but hidden. I just figure if I am throwing in new turbos, let me take car of the hard to reach bits now.

As for ceramic coating, I was looking at some companies to coat my parts before they go in. I had some ceramic Kooks long tubes in my last car and loved how they held up to the tortures of time.

top mounting turbos that small looks like absolute garbage, no one wants to see a pair of pea shooters.

XS run top mount 2835r's because that is how the kit comes from hks, it's also likely the only way that they can fit.

^^^yep.

Coujin's car for example. If it wasn't so incredibly clean, it would look ridiculous with those little snails up top:



Edit: Here's when top mounts are usefull:

omg thats a ******* RIDICULOUS ENGINE

[JDM-IMPORTS]

Kirk, we have a single turbo top mount setup (manifold & downpipe) at my shop for sale; we can also get you a turbo to match it. (see my FS post for pics).

The whole car is insane. On the list of the top 5 cleanest I've seen.

Coujin's R32

[mcfly]

thats rice of a skyline, top mount stockers. eww.

twin t04z's

[tokes]

thats rice of a skyline, top mount stockers. eww.

twin t04z's

More like twin TO4Z's, eww. Not everyone wants a car that his full boost at 7500 RPM's and is a dyno queen like that car is.

[mcfly]

not everyone wants a 1400 hp car...thats beyond the point.

two stock turbos sitting high up in the engine bay looks like garbage, that's all.

[JNS Performance]

^^^ agreed.

need some decent sized turbo's that fill the space. T04Z's are over kill and stockies are rice
