Everyone is going to have a different opinion. Pick one, they are both good turbos.

If you do a search for S400 67mm in the search bar there is like 4-5 threads with good info in them. Read through and that should answer any question you have. Thats how I decided on which turbo I wanted and I went with the S400 w/ 1.10 housing to run on my open manifold.

Everyones setups are different so look at both and make the right call.

am asking cuz am looking for something with the best spool and not much of lags on high RPM and the highest HPs

ashtons300zx

From what its been seen the s400 provides more overal power but lags more than the 6768, thats pretty much a difference in turbine wheel sizes one being a 68mm wheel and the other an 83mm wheel. But you should make full boost on the s400 by 7k or sooner at least from all the graphs ive seen of them.

Do u have a divided manifold? How much power are u trying to make? What size motor do u have?

Qatar s2000

ya it's a divided manifold, my engine is 84mm fully built, and am looking for a 900+ HP with a low 9 high 8 car

AROD

wait.... precision is coming out with the GT42 style 67mm!

meane30

Seriously!?

Qatar s2000

around when it's going to be out

AROD

yea, around march they are working on it. Similar to what miller ran at capital when he ran the first 8s on a 67mm @179.

Doesn't your car have a 6768 on it with a larger turbine housing?

meane30

Nope. 6765 with a 1.32a/r turbine housing. Nothing special

acup22

come on post some info about these turbos

SPOOLINmatt

aww man **** YOU!!! lol

oh well im buttoned up with my setup at least through this year. maybe they'll offer it with journal bearing unlike their other large frame bad *** billet turbos.

miller

It will only be available with precision's ball bearing center section. Soon Soon.

dturbocivic

there is a possibility that there is something wrong with your engine/setup. we have used the 4202 turbo and were hitting "full boost" around 6500-7000.

I have a PT6768 ball bearing for sale.. Only a couple dyno runs. Going to a 72mm.

I suggest a SX 66 airwerks.

garrett ball bearing ftw! journal bearing is hard to beat for the money...

That was a good read. Thanks for sharing!

if your looking for a 67mm turbo here is a better option than the 6768 and the s400.
Garrett GTX turbos are awesome and very reliable

The Garrett is very similar overall, but Borg Warner has more turbine housings to choose from and costs a fair amount less. With that said, I personally prefer DBB turbos and they will generally last longer and withstand more abuse.
