Hey guys, im looking for a little more oomph for my FC and im almost completly lost as to what kind of turbo i should be looking for. Im only looking to make about 320-350hp but im keeping engine response at the top of the list. I've been looking at several different setups. Ive been looking at the TD06sh and the GT35R so far. Im also looking at a t04 setup but im so confused at all the different combinations of T04's that i dont know whats what. Im looking at full spool at around 3500-4k or lower if its possible. Thanks alot guys -alex

A 35R is overkill for that goal. ****, for that little I'd suggest just a hybrid or similar, anything else is just a waste at that little power levels.

sounds like a bnr stage 2 would be perfect for that.

TD06 or GT35 is not a very good turbo for what your needs are.
For 300 - 350 hp, both turbos are being under utilized as both make more efficient power at higher boost levels (above 15psi).

A hybrid is recommended for ease of install and price.
A V-trim or H-trim will suit your needs for a compressor upgrade.

curious, how much power are the TD06 & GT35 good for? how do their power maps compare to each other? when you say V & H trim, does that apply for the compressor wheel or the housing? do they come in different A/R's? I also hear that hybrids seem to wear out quicker due to the increases stress on the shaft from the bigger compressor wheel. Im also aiming at a reliable setup as well. thanks again -alex

I saw a GT35 on a 20B make ~408 RWHP on the dyno at 7 PSI. That gives you the idea of the kind of power the turbo is capable of.

anywhere from 380-450ish on a 13B depending on port/tuning/etc for a 35R

The Mitsubishi turbos are not very efficient at low boost.
The Mitsubishi turbos really wake up at around 20psi.
It's almost the same for the GT35.
The GT35 was designed to make most efficient power at around 18psi to 30psi.
I don't have the compressor maps on me right now.

When talking about hybrids or compressor upgrades, we're talking strictly about the compressor section.
The hybrid / compressor upgrade uses the stock hot / turbine side and center from the stock Hitachi.
The compressor wheel is replaced - sometimes the compressor housing is also replaced.
The V-trim and H-trim are Garrett T04B compressor wheel sizes.

Compressor housing A/R is irrelevant.


If you're worried about reliability, then don't mod anything.
Seriously, more power means more wear.
You cannot avoid it unless you spend serious amounts of money - i.e. full turbo upgrade with external wastegate.

thanks for all the info Ted. Im going to look into a hybrid setup and im sure ill be more than happy with it

acutally ill take that back. Now that project a-spec is coming out with their gt35r kit shortly, im starting to reconsider if i want more than 350hp. Have you had any experience with either turbo setups. When i said said 350, i was thinking of a conservative street track setup but i guess a little more oomph would hurt. i understand that RE-Amemiya used a TD06-20g in their FC when they first started racing it. Is their some characteristics of this turbo setup that may differ with others that they could of chosen? Many people seem to be using the GT35 for high response applications as well such as drifting/track racing. They both seem like good turbo systems and i guess im willing to go up on power a little bit as long as they are streetable somewhat what are some recommendations as to these two kits? thanks -alex

RETed

R.E. Amemiya is heavily connect with Trust / GReddy.
Guess which brand of turbos Trust / GReddy uses...
It's a lot of politics.

Ask hIGGI about his GT35R...

at one time I was going to go with the gt35/40 (35r) but I am going to buy my turbos from precision turbo. I have spoken with them a few times and they seem very positive about helping you get the right setup for our rotaries. Plus their are some forum members around here laying down some serious numbers with their PT stuff. I just don't see garrett caring enuff about a few buyers to take any input from us on what works and what would work better. Customers service is 50% of the purchase

the thing is, i hear that larger hybrids can be somewhat laggy. Pretty much my main goal is going for a feel thats as closest to an NA motor as possible. I was think maybe a 60-1 T04E with a .84 hot side?

Bukwild

yeah 60-1 will do it and then some. Of course you will need a ton of expensive stuff now. But its better than getting a oil leaking hybrid

igottafc

iTrader: (6)

when you say a ton of expensive stuff, im assuming your reffereing to a new manifold, fuel control, and intercooler correct? Im planning on running on an safc until i get an EMS.

Bukwild

yeah ems, intercooler, blow off valve, wastegate, ss lines, manifold, new or cleaned fuel injectors, custom down pipe, electronic boost controller, and probably a few things I am forgeting. running a full t04 is not a good idea on a bandaid safc. Unless you rebuild your own motors

Now how does the T04e setup compare to a hybrid setup? would i be better off goin with a hybrid as far as response goes or would it be possuble to build a to4e to similar specs with a little mroe power? what specs would suit my needs? thanks -alex

If you're worried about this, then don't even bother with turbos.
People who bitch about turbo lag usually are not happy with any turbo set-up.
There is going to be lag, period.
It's the amount of lag you're willing to live with.
It's usually the significant increase of power that trumps the turbo lag issue.

My suggestion to you is to try and see if you can find someone with a set-up that you're interested in.
A "test drive" will confirm if you're willing to go through the process of attaining a bigger turbo.
