Turbo for the Supra

[MrSupra9-1-1]

So...I'm not completely satisfied with the bolt-on turbo that's currently on the supra. It's the main limiting factor for my build to make more power efficiently. It's design was from about 1996-2002.

So, I've been exploring options, and I'm not entirely convinced which alternative I should pick. Right now at 15psi, the turbo that's on there does about 380whp. The dyno couldnt' create enough resistance to push the psi up. On the road, it does between 18.5 and 19.5 depending on the outiside temp. I'm guessing it does about 420whp. I think I want better spool up and more power.

I've been on the forums (supra and supramania) for about a week. Everyone on supraforums is pushing for me to front the money for a precision or comp turbo. Somewhere in the area of a 6466 or 6262 or 6266. All which would go for about 2k when it's all said and done (supporting exhaust mods etc.).

The supramania guys suggest going with a hx40 (standard or super 40) or a Borg Warner. The hx40 would be in the realm of $900 and the Borg would be around $1500.

Does anyone have experience with any of these? The Supramania guys (mainly an mk3 supra forum) are really pushing for the hx40 or super hx40. The hx40 does about 60lb/min (480-500whp) and the super hx40 does about 70lb/min (550-600whp).

A few other guys have used gt35 & gt40r's and got between 500-700whp.

Are there other options I should explore?

I want to get some of the local guy's perspectives and put them into the mix with those on the supra scene.

If you need more info about my mods, here is my cotm thread with the mods on it: http://nemotorsport.com/boards/showthread.php?t=12627

Thanks in advance.

I'd vote for the 6262 billet journal, it'll spool just fine and make over 600 and under a thousand bucks.

That's not a bad idea. I was narrowing my mind on a triple ball bearing 62/62...but a journal would be about half the cost.

Any other ideas?

This ^ you wont regret it pte turbos are dope

[gtmustang00]

Go precision turbo. You won't regret it.

Well everyone already said what I was going to... Lol

Precision. 6262 is what I personally would like to get. I think it would be awesome for the Supra

i have an he351cw on my z. From the research i have don it flows 68lb/min. I got mine on ebay for 400 with 15000 miles. It spools fast and hits hard on my 3.0

Get the borg warner if you drive it on the srteet I'm assuming you're talking about an EFR for that kind of money. Do it. The time between when you hit the pedal and when you have boost (assuming you're above the boost threshold rpm), its almost imperceivablely small because the EFRs have half the rotational inertia of any other comparable turbo on the market.

[MrSupra9-1-1]

So...from what I'm gathering...all the turbos are good...so just get the one that fits my budget best?

[Leafy]

It depends. I dont think you'll be unhappy with any turbo sized to your power goal from a name brand (or even china). But some are better than others. I would rank EFR > PTE > normal BW > Garrett gtx with tial parts > other stuff.

Id go with the PTE 6466 Billet. Ball bearing if you can afford it but a Journal bearing turbo isnt the end of the world. 6466 is the new jazz in the turbo world. Get with the times ;-)

Are all the turbos you mentioned rotated setup? Or are some available in stock location. I'm assuming if you stay stock location you would have more money to put into the actual turbo it self.

I think I remember seeing a chart where the 6265/6266 doesn't have as much top end (over 600hp) but has better spool than the 6466. Am I right? EDIT: Found said chart and have attached it...

There is a guy with a na-t 2jz with a 6262 pte who made 520whp @ 18psi on pump. 3200 rpm stall, VPC/stock ECU. Stock fuel system too IIRC. So I'd be a little below that because the 7m is slightly less effecient...but not a huge difference since I'm all forged and freshly built.

I'm guessing that might be a good way to go b/c it has better spool? The 6265 might be a good choice too, since it will have good spool and a little more top end potential than the 6262...

I'm going to need a manifold..which is part of the budget. Is that what you're asking Shawn about stock location?
