Bump, come on vendors. First US vendors to do this will not be for lack of customers. Quit trying to be greedy and make us spend $3k+ on new turbos, manifolds and associated items. I want the conversion because spool up to me is the most important. Sure, 400 hp is nice, but not if you have to rev to the moon to get there. That is why I've not gotten a turbo upgrade (besides price), because I am not willing to lose eben a couple of hundred rpm on spool up.

Lets go vendors!!!

 

Not worth the Price, may as well get a BB 50 trim and have a 500WHP turbo spool up As fast as stock.

 

We need a replacement center section that has the ball bearings and has the titanium parts too. Anybody?

 

well all you really need is a bb conversion. you should be able to pick up a RS turbo (they have the Ti exhaust wheel and i think they have aTi shaft to) from Mitsubishi. although a vendor may beable to get a better price on them and (hopefuly) pass that saving on to the customers.

Chris.

PS. No vendors saying anything?

 

malibujack, where did you buy the JDM turbo with the titanium wheel and whatnot?

 

I'm waiting to see how Buschur's stock upgrade turns out. They tested Turbochargers. com's offering and it fell on its face. However, I'd kill for what they have available in the UK... more power WITH quick spool.

 

Did the US spec RS get the titanium turbo also?

 

Picked mine up from a Vendor in Taiwan. I have the MHI part number and I'll post it in a few days..

The Evo 7 RS Ti turbo is a 9.8, the Evo MR is a 10.5 (Same as the TME..) However i have not gotten confirmation yet that the MR's turbo is Ti, and the US market car likely will not be.

There are quite a few sources that I've found for the 9.8 Ti wheeled turbos.. There's not a huge demand for them therefore the price ranges from $300-$600, and the high side of the price is for a brand new unit. (Just so you know, it costs $450-$600 for a brand new USDM Turbo.. so its worthwhile to get one and keep it around for when you replace a stock turbo)

If it wasn't for the fact that it would cost $100 each direction for shipping, plus the conversion costs, I'd have sent it to a really great shop that I heard about in the UK.. Instead I'm going to wait for someone in the US to start doing the conversion and send it to them (With the specific instructions that I want MY Ti cartridge to be utilized) plus some clearancing and porting..

For the time being, I'm going to use the turbo as it sits, it seems that with the aftermarket manifold, O2 housing, and Ti turbo.. I'll probably get the characteristics that I'm looking for, with a total cost about $1000 cheaper than the cheapest turbo upgrade I've seen.

Most of us who consider something like this are repeatedly told "its not worth it, just upgrade the turbo" or that it won't produce the magic 500whp.. But on the street, who cares? I want a fun car to drive, and I want to avoid removing the components that make this car what it is..

Besides, some racing classes don't allow you to change your turbo or engine displacement, but allow you to focus on upgraded intake and exhaust components.. Offhand I can't think of anything specific, because I'm not that interested in drag racing, and I'm not a dyno ****.. Ok, so bragging rite is fun, but more can be said about 450+ WHP on a stock turbo than replacing everything..

Admittedly I plan on upgrading the head and intake manifold.. but ultimately you have to also consider that this is a daily driver for most of us.. so availability of parts should you break down is pretty important.. If you use "OE Configuration" parts, you can at least pick up a replacment to get you running again until you can get yourself home and going again.

Somehow I think people just don't like the people who go against the grain of what everyone else are doing.. I just can't see doing what everyone else has tried.. What fun is the hobby if your just going to do the exact same thing everyone else has? Sure, sometimes it works, sometimes it doesn't but how will anyone ever know if there's a way to do it if you don't try.

I get alot of question as to why I chose to go with a UTEC and a blowthrough MAF for that same reason.. and repeatedly get told that I'll just end up with an AEM EMS with speed density.. Well, honestly, I probably never would, because I'd have a hard time getting the car inspected and on the road legally. And the turbos just hit me the same way.. My gut just tells me that there's more in the stock configuration than has been even tapped, only everyone spends their time with bigger and better projects, and haven't tried to optimize whats there.

Ok.. enough rambling.. My point is that you just can't deny the R&D put into the stock components, now its just up to us to figure out how to exploit the R&D.

I'm not saying I'd never go with an upgraded turbo, or an AEM EMS.. However I just don't buy into a cookie cutter modification approach, it just leads me to look at "yet another identically modified Evo and yet another boring Import Mag Evo article"

 

waste of money imo, why pay 800 bucks so your stock turbo spools a little quicker

 

MalibuJack,

That's the most refreashing thing I've heard in a long time...

 

So you can push 27.5 psi

 

Ya know, I never even considered the possibility of higher boost.. Just optimizing whats there..

And the other post about a "Waste of money" If you really think about it.. this entire hobby amounts to a huge waste of money.. HOWEVER, I think its a little closedminded to make a comment like that. I think a huge turbo and quirky (at best) driving characteristics is the waste of money.

Now, this doesn't say I'd never do an upgrade.. But I want to see what I can do with what is there, I have no fear of wasting money because I do what makes me happy.

 

im with you jack.....lets see how we can optimize whats there before looking at huge turbos.....most people look at the peak horsepower figures and get all excited, but have they ever had to drive those cars in daily traffic...?? and lets not forget were talking a 2 liter here.....these things have NOTHING below spool up. the only time all that horsepower is good is when ur racing because ur rpms are always high anyway. different story cruising around....i have more mods than 95% of the people here but i really like that the driveability is such that my wife can drive it....(the stalling issue is a pain in the *** though).
so thats why like jack and some others, i am interested in looking at ways of upgrading the stock turbo.....i would be very happy with 40 more horsepower if the driveability is retained...if it cant be done then it cant be done and maybe ill look at other options, but lets see what happens....

 

if the conversation gives me alil more power for my boost, plus quickler spool im game.. as long as it doesnt cost me an arm and a leg...

 

If they make a turbo with spool as good as std, but more power, at reasonable boost (~1.2-1.5), then sign me up. I thought the 3037s was the one, but lately I read it's spool is not so good even spec'd in the small trim. Now I keep hearing about the 3071R, but it seems there is no hard evidence yet to support this new turbo. What is your guys thoughts on this question?

As for ball-bearing conversion for std turbo, here is what I consider to be the pro's and con's:


benefits of bb conversion to std turbo:

- improved spool-up
- more efficient (thus can take more boost)
- more reliable (thus can take more boost)

benefits of an aftermarket turbo:

- [same as above]
- more bhp


downsides of bb conversion?

- limited bhp (~420 bhp upper limit)
- higher intake temps because less efficient than larger turbo?

downsides of atermarket turbo:

- worse spool-up
