ok guys i need your advice!! wich turbo to choose for good response??
 

ok, i need a spicy turbo for my tII!! :yum:

up to now, i had a t60-1, but it was to laggy for my needs! i'm looking for a turbo setup, that can reliably hit 350 flywheel hp at about 13 to 15 psi and has great low rpm response!!

NO NEED FOR GREAT HP NUMBERS, JUST COOL RESPONSE!!

any of you have experiences with smaller, streetable turbos for 13b's???
:wink:

Well if you want best response Id say BNR Stage 2 or 3 stocker. The stage 2 advertises full boost by 3800rpm and capible of 325-350whp at like 14-15psi with supporting mods. Forget all of the technical stuff, but check them out.

well hes already on an aftermarket manifold, so theirs no need to go
something small like a TO4B

Well, I just gave him to only low cost, good hp, best response turbo I could think of this early in the morning. Youll be hard pressed to find a turbo to perform as good as a hybrid for the same price

gt35r with a .82 hotside should do the job nicely.

if you're on a budget, go for a t04b h-trim compressor, with .81/82 p-trim hot side.

ou yes that sounds interesting! :suspect:

BNR sounds nice, although i have a s5, but that should be no issue! but i think that one would be quite responsive... :bigok:

fact is, i sold my t60-1 kit and fortunately haven't thrown away my old s5 turbo plus manifold (although it's cracked)!!

garrett would be nice, but unfortunately i'm not familiar with the turbo nomenclature... sorry for being newbish :icon16:
have had some ideas about a gt30r, would that one not be enough flowing for 350 fwhp goals??
what are the important features (AR, trim, ...)??

no additional comments?? :spew:

I have an offer for a GT3071R .86 T25 Turbine! What do you think, would that one suit my needs? what about flanches, do you know which bolt distances it has?

bigger downpipes and exhaust are supposed to help spool up time.
Maybe try having a 3.5" downpipe made. The freeer flowing your intake and exhaust the faster your turbo will spool up.


a hybrid is not the answer for faster spoolup. a full framed turbo will be faster spooling.


Just go a step down in compressor size, like a t04b or something. or some flavor of ball bearing turbo if you want to spend the money.

GReddy TD06-20G hands down!

yeah, downpipe is like 3" now!
Intake is as free as possible! ;)

what is the difference between hybrid and full framed turbo?
so i should go with a T04 (compressor?), ball bearing or not??

how many rpm faster would you like the turbo to be?

Is this a hybrid (60-1 compressor on a stock turbo hotside and stock manifold) or a aftermarket manifold and full frame turbo.

Well, hybrids/stock turbo have AWFUL turbo manifolds. The turbo itself is fine besides the wastegate, but the manifolds are absolute crap although I'm still running one.

It all depends on what you're working with now as far as turbo and manifold, and how much you're looking to spend. There are some ways that are far more expensive than others.

Oh it would just be nice if that turbo could be developping boost at about 2000-2500rpm!
aftermarket manifold should be no problem, i could even have someone fab one for me ;)

so what would you recommend: BNR-upgrade with stock manifold?? or some garrett with aftermarket, or... i'm confused :eek:

uhm. All of the above

And I'd stay away from the hybrid if possible as a full frame turbo will be better in all ways but space and emissions.

As for manifolds, turblown.net, aspecracing, and alien something or other all make some nice looking ones.
I don't have a 60-1 so dont know how it spools compared to what you want. But I would try a tubular manifold and custom 3.5" downpipe w/ the 60-1 first, and get a smaller turbo if you're still not happy.

ball bearing is expensive, but ive seen people say it cuts spool time by about 500rpm.


Also wait for some people w/ more personal experience in this matter. Most of what I'm saying is forum hearsay, and some experience w/ friends of mine.

Also repost this thread in the single turbo forum as youll get input from more people.


On my personal car, I'm rebuilding the motor/turbo. I am doing 9.4:1 compression rotors on a ported motor w/ a h-trim hybrid and a tial 38mm ext wastegate welded to the stock turbo manifold w/ 3" exhaust. My goal is to make good power (compared to stock) and still look bone stock and pass emissions. I can't run as much boost, but it should make a wee bit more power all around.

thanks for advice man! :D

that was my idea too, to stay as stock looking as possible, but get some serious power increase!

but there is no chance to mount an aftermarket turbo to my existing manifold huh?
'cause in my opinion, the stock manifold is nicely done, with seperated exhaust runners up to the flanche...

hm.. maybe i should try the single turbo forum, thanks for the hint!

my first setup was the stock s5 turbo at 13psi, 3"exhaust, FMIC and it made no more power than 300hp at the flywheel, boost decreasedfrom 5000 to 8000 from 13psi to 88psi! that was quite annoying...
then i setup a turbonetics T60-1 hifi project. this was niccccce from 5000 to 8000 and a 380hp peak! but response was like crap!!!

still not knowing why, 'cause i thought this turbo wasn't that biig! :dunno:

Lots of variables, but no sense get into it since your old set-up's are gone. :(

Garrett GT-series are nice, but it might end up costing you a lot of money to set one up.

The regular stuff is fine, but it's all still a balance of response versus top-end power.
How important is the response?
How important is the top-end power?
This will determine what turbine A/R to go with...


-Ted

correct! ;)
but only the turbo setup is gone :)

so maybe the best way would be BNR then? any reviews on them BNR's?

so there's no way to bolt on any aftermarket on my stock manifold?

Nope, the stock turbo flanges are proprietary design - nothing aftermarket will fit them.


-Ted

ok thanks!

no reviews on the BNR's??

anyone can recommend them??

I haven't used any of Bryan's products, but to me a hybrid is a hybrid. :)
BNR does great work, and a lot of members (here) have used his products.
I still can't figure out how he offers his stuff for so cheap! :)


-Ted

you can do a hybrid if you want. I'm just saying a tubular manifold and full frame turbo will be better than a hybrid.

Hybrids can make some decent ponies though. Some of the bigger ones will do 350-400rwhp, but 400rwhp is the limit for them, but thats a ton for a hybrid.

There are plenty of reviews on the hybrids, you just gotta look for em. Start by searching the 2nd gen forum for "BNR" w/o the quotes of course.
you'll find a lot of threads that may not be what you're looking for, but I promise there are some "review"ish threads about them. Many many people have the BNR hybrids.


Ted, I heard your ex-partner was making a part to bolt a non-fc hotsided turbo to a s5 manifold.

Yeah, he passed that idea to me, but I didn't care too much for it.
I dunno if he's still doing it, but we've got other things more urgent.
We're restarting the production for the front camber plates / rear pillow balls, but we keeping our businesses entities separate - I'm buying the units at wholesale, and the extras I'll resell through my FC3S Pro website.


-Ted

okay so i'll do some research! ;)

one gua at the single turbo forum made me an offer for one of his MasterPower turbos! do you know this brand? never heard of it? cheap stuff? ebay, XSPower alike??

I wouldn't touch it.
As much as the supporters like to claim, I put Master Power in the same category as the SSAutoChrome / XS-Power crap.


-Ted

the Master Power/ SSAC/ XS Power turbos have ~alright~ cores, but the housings are crap
