If you were to provide the turbo manifold, GT Racing could come up with a ceramic ballbearing turbo kit. They make some of the best custom turbo kits I've seen. They haven't made an Evo turbo kit yet as they are in Canada, but they do make custom one-off kits for the right price and they have a lot of U.S. clients. If you're interested PM me and I can pass on to you the contact info.

 

Garrett does not make T3/4's anymore. THey are using all GT series turbos. The GTxxR's are ball bearing. If you have T3/4 than it is made by another company. I myself would run a GT30R for up to 500 HP and a GT35R for 600+ HP but you need a custom manifold to do it. Garrett makes VERY few reverse flow turbos.

 

I guess a few monkeys missed the part in blue Eric... I don't think they realize how damn many of us want a turbo with hardware that bolts in between the STOCK manifold and STOCK O2 housing... nothing more, nothing less.

 

In order to have a custom bolt on turbo kit built, for development purposes the manifold, whether stock or otherwise would still need to be provided.

 

?

 

My bad. I miss read your post.

 

Hmmm, I didn't realize that using an internal wastegate was cutting corners. As long as you can control the boost it makes for a much cleaner installation and much easier to package a kit.

We are also developing a turbo kit, actually it is done. We are just waiting on the manifolds to be cast.

The turbos we are going to offer are going to be Garrett units with custom cast turbine housings with internal wastegates. One thing I am sure of is we have gone faster than any other vendor out there using a 4g63 engine.

The turbo that is on our Conquest powered by a 4g63 engine is internally gated. The car has run 8.7 at 151 mph with this internally gated turbo. It is on a 2g cast iron hand ported manifold. reliability issues with this set-up is perfect. This turbo will also be available for the EVO8. We have made 650 whp with it.

Our turbo kit is going to use the stock EVO8 heat shield and will appear to be very stock to the onlooker.

Good engineering does NOT equal cutting corners.

Take care all,

Thanks David. As always a professional and intelligent response unlike many other vendors and manufacturers. I agree that results and quality is what is important. The design will follow that. I myself prefer external gate but for some applications it just isn't necessary and increases cost.

 

Oh I agree you don't need to have a ext. wastage as long as the internal one works and the install is always much cleaner.

 

Yes that is what I really want. A bolt on turbo with BB.

With any tubular non stock header. you will have tremendous under hood temps. The solution is header wrap or some type of ceramic coating. I recently switched to an equal length header on my dsm. I had everything coated except the turbine housing.

 

Eric,

speed box from Japan makes a bolt on turbo similar to what power does for subaru. i think RB motoring had one that they were trying on in this thread:

https://www.evolutionm.net/forums/sh...ight=speed+box

let me know if you want one and i can get it for you. (i am also dying to try one out so i will order 2 at the same time for a good price)

 

ignore the above post, i don't think that one is ball bearing. i have a catalog at home so i will try to find another one later on.

 

Thank you for the offer. But yes BB is what I want.

I agree with Buschur that an Internll does make a cleaner install, that is not nessecarily cutting corners. The problem I have with internals is that they make the turbo spool slower for 2 reasons.

A) The turbine housing is not nearly as nice. A 4 bolt ballistic Garret unit spools noticeably faster then a 5 bolr bastard flanged garret unit. In addition to that internals ALWAYS leak, while externals provide a perfect seal. Internals are always at the sacrifice of spool.

B)In addition to that internals ALWAYS leak, while externals provide a perfect seal. Internals are always at the sacrifice of spool.

So yes internals do have their benefits, they are cost effective and you may think of them as a cleaner install, although I like external looks, but they are NOT equal.

In addition, the conquest example is silly. The larger the turbo and the more boost you run, the less gate you will need. Its the street cars running lower boost levels that you need to control.
