If you have used either of these, please post comments, feedback, opinions.

Quick comparo:

T3 Super 60 - good to 350hp, internal gate
Compressor 60 trim, .42 A/R
Turbine 68, .48

GT2554R - good to 270hp, internal gate
Compressor 60 trim, .80 A/R
Turbine 62, .64

This will be used on a Y7. The Super 60 should spool quicker, and can be bought almost $200 cheaper. I'm not planning on going over 200hp. cheers

the 2554 is a very small turbo. It will spool quite a bit quicker. Its even smaller than my 2854R which even still, makes a full 7psi at less than 3K. The GT equivelant to the Super 60 is the GT28RS... both of them flow about 35 lbs a minute.

Damn Jay the appearance forum is further down the page
but really tho the GT255a is tiny, it's about the size of a progresso soup can. ok maybe not that small, but close. Look into something a litter bigger, it's always good to have a turbo that gives you some room to grow. super 60 or GT28

I know all this, have you used one or are you familiar with the performance?

Haha smartass I won't be growing, although I'm leaning twords the Super 60.

I have a 28R, my friend has a Super 60 on the same car (they're both D17s, only difference is I have VTEC, but thats more or less irrelevant to the spool, since full boost is well before that), I assure you, the 25R will spool quicker, since mine is bigger than a 25R and it still spools quicker than a Super 60.
They've been dynoed, back to back on the same day, I made an extra 13 HP with the same boost level, but we'll put that part on vtec. I can dig up his graph, the power was incredibly linear, whereas with the smaller ones you'll get a bit more power down low.


Price diff? Yeah, well ball bearings cost more, the GTs more on top of that for the housings and inconel impellers. Its probably more than 200 bucks by the time you add in the inlet/outlet flanges, oil flange, etc.. for the compressor, etc... it comes out to about 900 bucks for the GT.
Sounds like you got your mind made up on the T3 anyways....

Cool. I'd rather stay cheap and spool a little slower with that said. I guess I thought the smaller A/R would spool quicker.

^^For the same size impeller, but the GT25 turbine wheel is physically smaller.... so it will take much less air to rotate it.

Ahh, ok.

Did that hurt when you pulled it out of your ***?

Hey thanks, I think I'm set on that turbo.

It's folks like you that make learning that much easier.

I have a mildly built d16y8 w/ Garrett t3 super 60 and love it!! Contact Viren for the turbo, excellent prices!!!

Cool.

The t3 equv to that gt2554r would be a T3 50 trim with a stage1 exhaust. Even that turbo can flow more than a stock y7 can use. Get a 2.5bar map sensor for $15 and push it up to 13-16 psi, and you're at a good 220-240whp. Not to mention they cost $250 less than even a real super60, and $100 less than a [non-super] 60 trim T3. Since you're going for just 200whp, anything bigger than a 50 trim t3 or t25 (with big AR's) is just going to increase your spool time. Both can hit 200whp at 11-ish psi, and if you have a restrictive exhaust, get the 2.5bar and bump it up near 16psi.

Personally I'd go with the 50 trim T3 - infact, I am. My d16z6 is almost finished, and I'm going to daily drive it till I finish another car, and run ~15psi with the 50 trim T3, stg1 .48ar. That way you can use the $$ saved to plunk into a better manifold, then upgrade the turbo later if you need. <U>I ran a t3/t04b s-trim (a tiny bit bigger than a super60) with a stg1 .48 exhaust, had 10psi by 4k with a stock z6, 3" dp and 3" exhaust.</U>

I was planning on using the Spoolin log mani with a HKS Hyper and test pipe. I figured that will work fine with a small turbo. I didn't know about the 50 trim. That should allow me to stay around the 15psi range and get to my power goal. Very helpful info, thanks.
