Coors light?
You can go lower! Keystone baby!

Let me know what you're going to sell. I'm thinking about upgrading my 240 turbo system during my engine swap.

Woah, I walk away from your build thread for two days and your suddenly liquidating your build?!
Damn dude, let me know when you get your fs ads up I might get something from you. I do see where your coming from though, having a proper garage is the only way to go afaic.

WD, I am seriously going to try to make it. I need to get my 240 ready to drive up there.

I'm on the lookout for a good turbo and manifold. Something that will max out around 400whp or so. I probably wont take it that high, but I like the efficiency and such.

Codyace, on Zilvia, is running a modified stock SR manifold (swain coated, extrude honed, 38mm external gate), aftermarket downpipe/elbow (extrude honed elbow, swain coated), with a new GTX28##R turbo (coated housing). Not sure of the exact turbo...

On an SR, hes over 400whp - A KA should do as much and more, with the X2876. If I get to keep this project going, once the dust settles on the house I am copying his exact set up.

DIsco Potato, up in this piece. :woot:

The GT28RS, or 2876R whatev, is a sweet turbo. I've always been against spending over $1000 on a turbo, but you can but them on Ebay now for cheap...actual balanced ones. A rebuild with genuine Garret internals and a rebalance is only 350 at g-pop.

I have a GT2860rs on my Miata. It's pretty good for that, but I'd definitely want something bigger on the ol 240

No sense going bigger. Bigger only gives you more lag. Lag sucks. 300whp in the S-chassis is a fun car. 400 and you really have to be paying attention to what you're doing.

Hope you are still going threw with this build, looks pretty close to my setup. I too bought the garbage a** manifold from godspeed and I am running into the same problems. My biggest problem is finding the "velocity stacks" for the intake mani. I cannot find these anywhere. Xcessive does not have them listed on their site. Are they needed? What problems am I going to run into without using them? Do you have a part number so I can order them?

With 400+ whp I'd be seriously wishing for a different set of rearend gears. Something in the 370 range would make the highway much friendlier. I do a lot of 75+ mph driving.

a GT2860 is way way out of it's efficiency range at 400whp.

Really a 2.4 liter flows more than it really should be used to anyway. The KA's only saving grace is that it doesn't make s*** for power in the upper RPMs, and neither will this turbo so you'd just shift earlier.

I'll see if I can make one of those for a GT2860 and a KA.

They are not listed, but they still sell them. I sent them an email asking if they were for sale, I paid ~$100 for them and the remote mount IACV plates.

In the upper RPMs maybe, but down low its responsiveness is what makes it so great. plus the GTX wheels and housing options let you tweak the responsiveness for a wider effective powerband.

Like I said, Codyace's build over on zilvia is what I'm trying to emulate. WIth the exception that he is running an SR....

Cast SR MAnifold (extrude honed/swain tech coated/modified for a 38mm v/band external gate)
Cast SR DP (extrude honed/swain tech coated)
GTX2867R (swain tech coated turbine housing)

Hes cresting 400hp rather easily with his set up, and the boost response is supposedly really good.

Granted, Im running a smaller turbo, and have not yet had my manifold honed/coated, but the whole point is that I can make those changes a few seasons down the road, once the motor is in a car for $1500-2000 grand.

Also, I'm looking at 280Zs....the second I close on this house I'm picking up a shell.

I made that GT2860 comparison chart for a KA, just waiting on NICO management to upload it :)
I could email it to you if you'd like too.
I pulled the map directly from turbobygarrett.

Without cams cams the KA quits making power at like 5500 rpm. The 2860 may be just going inefficient right around there. EasyE ran a 2860 at over 20psi and reported that the turbo started dropping off past 6k iirc. I'll have to email him and have him come check in here. First hand info is always the best.

I would like to see that, but were also not talking apples to apples...the 2876 does not respond the same as the disco potato (2860), and has a bigger compressor. with the newer wheels and aero tweaks on the TGX turbos its supposed to resond even better.

It what I eventually want to upgrade to, I just got such a good deal on the 2560 that I could not pass it up.

They are listed. You have pull up the actual manifold and read threw the 3 paragraph explanation and in blue letters they mention the tubes. Had to click on the blue letters which linked me to the listing. Suprisingly the price has dropped and I paid 69 bucks shipped. Xcessive shipped the next day :) they used fedex which is garbage and will take 6 days to get here but I'm not in a rush for the price!!!

Is an entirely different animal than the 2860. The CFM alone separates the two by a huge number...i'll dig up the specs.

Indeed. One of the best options for the KA if you don't mind spending bank or buying an ebay version.

If you already have a smaller T2 GT(R) turbo, there are companies popping up that will upgrade it to the larger compressor/turbine housings - along with the neccessary rebalance. It cost more than just out and out buyng a new one, but if you've already sunk money into a GT2560R like I have, for $600, they'll upgrade it to a 2876.

Either way you have to pay to play, the ebay options are just too risky. I know that some people are having a good experience, but it worries me in any event. I just checked out Amazon for the hell of it, and Godspeed is hucking their 2876 clone for $325 plus shipping. It is enourmous.

http://www.amazon.com/Godspeed-Universa ... ds=gt2876r

But its not a Dual BB turbo, dual Journals with a massive compressor...I wonder how its flow map compares to the real deal, there are going to be frictional loses...
