best companies?

in every ones opinions whos the best? trubo acces companies and best turbo companies alot of my friends with there supras got hks and tell me hks is the best way to go but i hear apexi and greddy is good? but im still learning

There all garret based units. Its basicly just different names you are paying for with different companies. Just look at compressor maps to find the best turbo for your purpose.

sorta...

some of the higher end hks turbos use their own compressor design and a/r

garret centers, there all based ont he garret design. Changing the compressor and a/r is something everyone does. It really makes no difference tho.

Some manufactueres go over and above and make antisurge housings and such.
Get the best you can afford that will put you in the proper power range.

i love how you downplay everything
LOL

naw i like this guy hes a smart guy .seems it. how do you pick turbo size? because i wanna bvuild my 88 then after market turbo i dunno how to get one i want a garrett ball bearing but do they come in sizes or poer ranges or what?

yeah

you need to match the turbo to the amount of power you're making

if you shoot them an email with a power estimate you should get repsonses

the power with the stock turbo or the power the motor its self is putting out?

Just tell me ill find one for you.

Give me a price range for what yu want to spend on the turbo alone and what kind of power you want to make. Ill find you one that will work for you.

price is no deal i build 4wheelers adn sell them race 4 wheelers i usually have a steady flow im known around her efor 4wheelers but i also own a skateboard shop and im looking to make about 4-5 maybe if i coudl 600 hp i got a another turbo 2 motor ont eh way imam pull apart and do eveyrhtign i can to that and se ehow much hp i can get out of it

LOL, price is always ALWAYS a limiting factor with these cars. And from the sounds of it, you shoudl not be building your own motor. 500whp is pushing the 13B HARD, 600 is even harder and will not be drivable at all. The lag alone will be HUGE no matter what turbo you are using.

But it is doable, but you need an experance engine builder to build your motor, its not really one of those do it yourself kind of things making power like that.

yea i been doing my homework and this past weekive realized imnot doing it myself and foudn a bunch of companies but its hard to determine which ones to use who does good work and knows whats up theres somany companys but no0 one local.. so im trying to figure out who can help me hook my motor up

Garret and then talk to the tech and tell him exactly what you want to do. Lag isn't nor should be even at 500 which isn't bad for a 13B-rew. 1 way is to have a smaller turbo you don't need a huge turbo to push 500-600 hp. 2. Take a look at turbo insulators they will also aleviate lag problems at decent hp levels. From what I've seen 13B-rews really can be pushed to 900 hp before they start popin like cherries anyway then you just need a nice 2Jz for under the hood or even better an ls1
:biggrin:

TII's arent equipped with the REW. FD's are.

500whp, you will experance lag. To make peak power of 500whp with the smallest turbo possible you need to run high boost (high20's to low 30's), lag WILL be a factor as porting anything less than a full bridge port will not allow the exhaust gas to escape fast enough to fully spool the turbo.

900whp is VERY high for a 13b of any variation. They will pop far sooner than that. You would need a fully dowled and pinned motor, full race porting, big turbo, high boost, water injection, ect ect to acheive such numbers and recieve little reliability out of it.
Trust me i have built lots LOTS of these to huge power levels. 13b's are not designed to be pushing huge numbers.

I was reffering to the FD... Also lag really shouldn't be as bad as you say it is. Signals R34 has a single T layout and is pushing 1200 hp and compete's in timeattack which leaves almost no room for lag.

On a time attack the only time there would be lag is on inital take off. The rest of the time the car is making boost so lag would not be an issue.
R34, well thats 2.6 liter with a stroker kit, i think its a 2.8, so that accounts for more exhaust gasses. Means faster spooling turbo. There are ALOT of factors to look at when talking about this.
You cant compare a skyline to an RX7 in that way.

Yes... The R34 has a stroker but also if the FD were ported and worked internally not just a simple bolton turbo making 500, or you could do as the veyron engineers did and make a twin. The veyron is quad but it uses this method duplicated... 2 big turbos an 2 smalls the smaller spool the big or you could just a turbo mounted to the exhaust that would aleviate spool time all together not sure the Z-tune might have that.

z-tune is just like any other gt-r, the turbos are the same size and are fed at the same time

FD's being ported with a turbo dosent come close to a R34 with stroker kit and a big single. The R34 is moving more than twice the volume of exhaust through that the RX will.
