just don't buy from MJMTurbos.com I paid close to $450 for a new t3 S60. ended up with a t3/t4 with a ".60 trim" wheel...sigh (which was built poorly besides that, blades hit the walls). Took about 2-3 months and lots of talking with the better business buearu (Case #: 85003007) to get my money back. And by that point I had taken it apart; Keep the chra, turbine, and 360° bearing from it and sent them back my old parts.... ;)

what they gave me vs. T3 45 trim (large ass muther fucking wheel)

(they machined out the housing and backplate to accept the wheel, the talked about laser/infared percision accuracy and all this bullshit. The compressor blades hit the walls on the first boost, the wastegate never worked, and it wasn't what I asked for. On top of that the guy who ran the shop refused to talk to me half of the time and hung up on my all the time when I was troubleshooting the compressor blades (I had no clue it was the wrong turbo at the time). He seriously was like "are you challenging the quality of my work?! and who are you?!" His shop was somewhere in AL (mjmturbo.com), but some random chick that took care of everything was based in CT (mjmturbos.com). Such a scam place.

So WOTs deal doesn't sound so bad at all.

acutally here's a quote:

T3 0.48/0.60 Watercooled $445.00

Not a bad deal on a 60 trim, will work just as good as a super 60. Stinks they don't offer the smalle A/R combo

Guillaume at Blaast can hook you up with whatever combo you want, including compressor covers, most Garrett A/Rs etc. Not sure why you'd really want a .48/.42 though. His rebuild prices are good but shipping to Canada can be pricey.

still make big power and faster spool with the smaller A/R

We have different ideas of "big power" I guess. Unless you're lugging around at 2k rpm all the time, quick spool is overrated.

Frank

no it's not.

It certainly is on the 7 turbo cars I've owned. I've gone with bigger turbos on every car I've owned. Having a "slower" spooling big turbo that stll makes 50whp+ across the board vs a small turbo that spins quick and dies over 6K just doesn't do it for me. But to each his own. You've got a 1.6 also (which I had) so your turbo choice and spool characteristics might be different than mine.

Frank

I'd say displacement plays a big role in the majority of decisions on what one wants from forced induction. Just the displacement increase makes a big diff in daily low rpm driving- which is then compounded by even the slightest amount of boost. My boost onset is at 1800rpm with a t3 stage3 48AR, t4 50AR and it's immediately noticeable that boost is buidling from that point on. I now have a better understanding of how AndyFloyd drives daily with a 3271 (which is often referred to as a big turbo for a small 4 cylinder) - he's got 1.9L of displacement, a more efficiently designed turbo, a free flowing exhaust... all that and more make a big difference in how a turbo feels. Braineack's setup is probably at the other extreme - right?

not really, T3 S60, starts to spool at 1.8k, reaches 12psi by 4k. But I've ridden in miatas that build boost faster, and I like the charateristics...it's really a compromise between ultimate power output and initial torque.

I meant that you're not running a 3" exhaust, no cat, external wastegate, and have 300cc less displacement, therefore you run a smaller turbo.
