hey guys.
I just ordered head setup with tomei components including 270 degree cams.
I'm going to finish built up the block w/ JUN rods and CP pistons. So, i was wondering which turbo should i get
to complete this car that has balance and power.

It would be very appreciated if members on fresh alloy give me some advice.
Thanks. http://forums.freshalloy.com/images/graemlins/smile.gif

You have to give more information about what YOU want out of the car. Power goals, powerband, driveability, etc. BE SPECIFIC!

I would expect around 400 hp.
if the turbo kicks in 3000~3500 rpm range that would be my preference.
drivability, the head setup is pretty rough so it wouldn't be matter too much.

GT2871R .86 A/R would be about the smallest turbo and fastest spooling that will hit 400hp that i can think of.

I vote 2871 also. I think you'll have a lot of fun with it and should be able to get close to your power goals. I think it will spool a little later than 3500 but not much.

T3/T4 50 trim, .48 ar

Thanks for your reply guys.

I was going to build the bottom end when i recieved the head.
However according Jeff from HT,
He wouldn't recommend to do it.
Because it would be hard to find the mechanic who does the
job right and built bottom end always had the trouble in
an year.
what do you guys think?
Thanks.

It is not neccessary to build the bottom end when doing an upgrade. The GT2871R with either the .64 or .86 AR are both excellent choices. I have the .64

There are several other turbos that come to mind. You could look into the T3/T04E 50trim and STAGE3 wheel. This is a ball bearing turbo that is known for higher HP and decent spool. This will allow a Top mount manifold and external gate. This turbo is cheap, but reliability is questionable.

Once again, this is not a ballbearing turbo. http://forums.freshalloy.com/images/graemlins/rant.gif

as i've said before...we've pushed a bone stock bottom end to 570 hp, and it still runs strong. there is no need to build the bottom end for 400hp. I'm sure others will disagree with me, but if you have a competent tuner who knows these cars, then they will stay together fine.

i'll vote for GT3071R with .63 A/R. it's really tough to push a GT2871R with 0.86 A/R to 400whp.

I was told when shopping for an upgrade that the stage3 wheel is BB.

Enjuku ran those turbo's on the twin drift cars...they told me they were BB.
GREASER ran that turbo on his drag coupe and said it was BB.
A friend bought that turbo from phoenix and said it was BB.

So how is it not BB??

Unreliable because they never last as long as the GT series turbos.

the standard t3/t04e is not a ball bearing turbo. it is a journal bearing with either a 270 thrust bearing, or 360 thrust bearing option.

garrett released a while ago, the ball bearing upgrade center sections that fit in your T-series housings that you may already have. precision turbo was blowing these things out when they were first released because they had bought something like 5000 center sections and needed to unload them. thats why they were so cheap when they were first released, like under a grand cheap. Now that they realized how well they sold, they're priced right up there with the GT ball bearing turbos.

Turbonetics also had they ceramic ball bearing option for their t3/t4 turbos which is more than likely what greaser had because it was so long ago.

If enjuku told you that the standard 50 trim stage 3 wheel t3/t04E is a ball bearing turbo, then whoever you spoke to there must not have known what they were talking about.

Your friend probably got the ball bearing option that they offer from garrett.

that is how that turbo is not ball bearing. believe me, i have 1 sitting here on my shelf i've been trying to unload.

And for the record, Enjuku didn't have the bb center section on their cars.

I wouldn't say they are unreliable. They are simple and have less lines since they are not watercooled. Even though they might not last as long as a GT series turbo, they are rebuildable whereas GT series BB chras are not rebuildable.

Also those T series BB chras only came out like 4 or 5 months ago or so, so if someone said they had one before that you might raise an eyebrow.

"Stage-III" and BB have nothing to do with each other.

Then i offer my apologies. I was extemely misinformed. Which kind of sucks because that was the turbo i was looking at first before i bought the GT2871.

I looked at the 50 trim stg3 with a bb chra but the price went up so it was not much cheaper than a GT series bb turbo. I decided to just purhcase a straight gt30r instead and should order it soon.

The GT30R is lots of fun. You'll love it, I sure do.

pay attion there, the guy wants something spools fast...my 30R gets a full boost around 4500rpm with 264 toda cams, i am sure it's alot of fun...but...little too lag for him.

What do you consider full boost? My gt3040 made 20 pounds at 4500.
