Yeah i could get either type the Mitsu High flo or the TD05/06 as well. I'm just tossing around ideas, i'm not really up for spending an extra $1000 on a turbo only to acheive 10kw gains across the board based on the mods I intend. My target is about the 200-220kw mark for the 1st stage of modifications, then of course seeing how i feel towards the car at that stage to commit more $$ to it. I dont want to do things 2x over so thats why i'm taking my time to work out whats best for me and my bank account. I want a tuff streeter but i'm not willing to spend more money on a bigger turbo than i require. I'm not after just flat out Kw i want in line speed/power as well as circut driving abilitys so a spool past 4000rpm doesn appeal to me in my case.

I see where you are coming from, but in all honesty... when circuit racing or on the street.... the only time you are below 4000rpm, is when you are cruising. On a circuit, you would be continually above that. The most important factor that most people forget, is that larger turbo's like the gt35r, when properly setup..just because they dont hit full boost til 5000rpm, doesnt mean they arent making power at 4000rpm. From my experiences, they usually make more power than the big 16g, at lower rpm, and once the rpm raises, well so does the increase in hp. I strongly would advise you to really work out where you think you will be at within a year of doing this. Do you really think 220kw is where you will stop, if so, just a 20g comp in the big 16g will suffice, but if you want more, something of gt35 origin is really hard to go past. Great on the street, and the ability to crank alot of boost and really let it shine.

Strap it on and find out...
Some things that contribute
Engine Management
Intake path (from filter to turbo and from turbo to cooler and cooler to TB)
Exhaust size/path
Dump size
Exhaust Manifold
Intake Manifold
All those and more can be changed to change spool times. You really won't know until you strap it on.
good turbo's... check out dsmtimes.org and you can check what times they are running to give you an idea on power
they are knows to bit a little laggy but big turbo's are like that..
if your only after 220kw's..
i'd recommend a big16g with supporting mods to suit
theres a vr4 running 11.9 with this turbo.... very streetable =)
and cheap tooo!
14b's can run 10's on the right setup.. its not just the turbo mate.. think about getting the other stuff first..
- cams / heathy motor / exhaust / management etc etc...
i had a tdo5/6 23g.. i only made 160kw's at all wheels... reason..
250,000km old motor with a big turbo.... would have made the same power if i had a good motor with the 14b...
but dont look at the max power of the turbo.. look more into the power band... if it makes power from 2000rpm all the way to 7000rpm, that is 5000 rpms of usable power..
whereas a bigger turbo, eg gt35.. will make power from 5000 to 7000.. it may make 50 more kw's but you only have 2000 rpms of usable power...
All very helpful knowlege guys, currently my motor has only done 53,000kms which is quite young i would think. I might look to go for the Big 16g with 20g compressor wheel along with a set of cams and management and see how that fairs, I can always sell the turbo and dump and upgrade to the GT35 with manifold and gate which isn't really doing things over as I see it, from what i read a Big 16g/20g would be a good stepping stone and fairly inexpensive to really get my mods underway and support the overall 1st stage mods.

Just a thing before you decide this...
Go fix your fuel system. 4G63's come from the factory with a fuel system that's at nearly 80% capacity from stock. So you'll need Pump/lines/regulator/injectors FIRST, big screwoff turbo SECOND.

I think before people make statements, judgements of larger turbochargers ie GT35R, they prob should actually have first hand experience. Where do you get power from 5000-7000rpm with a gt35r. I've had setups on 4G63's that reach full boost, with a .82 housing at just before 4700rpm. Mind you, 10psi can be seen as early as 3000rpm. That engine pulled 348kw@wheels at 8200rpm. Its power band to me was more of 4500-8500rpm, and i like to see any smaller turbo even attempt to stay with it in any gear. Remember when racing, you are always well about 4000rpm, and thats drag/circuit whatever... Even on the street it is absolutely perfect. It all depends on what you want to achieve and if you are prepared to put the supporting mods on the car.

4000 rpm fullboost is not what i'd call streetable.
But to each their own.
Also, 348KW @ 8200? WTF?

How is 4000rpm fullboost not streetable?
348kw@8200 at all four... is the way to get a car to go. From 4000-8000 its just hang on.

We have very different ideas. I'm going to leave it at that.

Quite possibly.. but yeah, I'll post my dyno charts once my current evo is finished, and you can make your own decisions. I'll overlay them with Big 16G charts, and you will be shocked at how little difference there is down low. The GT35R properly setup, makes the same power(down by like 5hp) til about 3600rpm, and from then on, well the 35R just keeps making the gap bigger and bigger

the gt35 that started making power at 5000 and revved to 8000 was jstyles car... (.82 exhaust housing, 272 cams)
as for dre's he's got the gt30 and that was a little on the laggy side also
if i recall correctly, it was at the time building boost in the 4000 range... only revved to 7000 (.63 housing, evo cams)
so yes i've experienced it, and the power is big once it arrives, its just getting to the power takes a while..
the best power band i've experienced was honestly pashn8's car..
from 2000 all the way to redline.. a nice push.. not too hard but u could feel it! very smooth..

Odd that Jstyles car started making power at such a high RPM. I agree they dont start making max boost til that stage. But all that I have experienced certainly make good power up to that point and then really take off.
In an evo, they tend to sit at a higher rpm, hence the lag not being as noticable. To me, having such a huge rush from 4500rpm is perfectly streetable, as having alot earlier doesnt do much as most setups run out of puff once the rpm increases. Sure I agree properly setup Big 16G's will pull to redline, but they lose the urge much sooner than that. I guess it really depends on what you want. Personally, I am quite content with having power from 4000rpm and up.
Yeah exactly right.
You have to take into account the different drivetrains here. The shorter Evo ratio's make a BIG difference on the street against the GSR adn VR4 ones. You basically add another 1000rpm onto your comfy revs on your VR4 and thats what the EVO boxes give you.
4krpm is a great spot for the sledgehammer boost with Evo drivetrain!

Yup, but depends on your idea of what 'streetable' means. Many people would change gear by the time they hit 4500-5500rpm so maybe they like boost coming on earlier at 2000rpm in preparation for spooling into the next gear change. Others might like to give their car a little bit more oomph and change at 6500-7000rpm where a turbo kicking in at 4000rpm would better suit them. Depends on how you drive your car really and whether you want instant 'punch' down low or all out power and top end.
Personally I would like a setup that enables you to drive around mostly 'off boost' all day under 4000-4500rpm and IMO I think that is 'streetable' as its tame'ish and saves you fuel. But when you really want to give it some stick you know the turbo is gonna kick in at 4000-4500rpm all the way to redline for max top end :twisted:
I love driving smaller turbo cars for that instant punch and quick acceleration feel it gives you when you put your foot down. But I also love the feel of when a big turbo kicks in and makes you hold onto sheer life... damn it... I need 2 cars! lol :lol:

I just had a 20g wheel fitted in my spare 16g with a 34mm watse door.
It'll cause a delay of around 2 - 300rpm but around 15% more torque to
play with from 3,500 to my max of 7,000. I'm making a tube exh mani
to blow down into this which should give me back 200rpm spool up time.
Not throwing the hiflow on untill I finnish the exh mani. A new chip also.

i posted this before but got deleted. i am running a gt35r .82 on a std vr4 motor with 272 cams and gears and haltech e6k.. the fuel pump maxed
out as you can see from the boost line. this is in a cordia but should give a good example of the turbo on a std motor.

Nice work
Its good to see some ppl final geting on board here with the big turbo = Good
Benny, you know what your old car
<== is soon to get
with this evo gearing im doing 3500rpm just reversing out my driveway LOL jk, but realy your at 4000rpm b4 you know it.
