Turbo Qs for Damian, et. al.

[Vettezuki]

What do you know about aftermarket turbos and related stuff? I'm doing some research for my brother's VG30ET (Nissan 300ZX, 3L single Turbo). So far, it seems the Garrett T3/T04e (whatever that is) is the best choice for targeting the 400-450WHP range.

For reference here's the main thread for the engine build in total.

I know some, but my buddy sells Garret turbos and has no problem helping you. I can get the number if you'd like?

But the T3/T4E turbo is a good one, that was my next choice for a compressor wheel. It's bigger than mine. What about a Holset HX35? The 2nd Gen Eclipse guys are getting 500whp out of them easily.

I'd be grateful for any contact info. As for turbos, it's a cost benefit analysis. Another one people were recommending as awesome was the HKS, but holy Christ they were radically more expensive.

[Damian]

HKS is over priced if you ask me. Garret GT series turbos are always a good choice as well.

He told me you want part number: 715583-4. I think that's a T3/T04S 60-1 trim.

Ask for Nick and tell him I told you to call him. They are located in Fontana across the street from the track.

Have a picture of intake and related parts?

Thank you very much. I'll give him a call. I searched for that part number on the interwebs and no dice though. :huh: Maybe that's just their part number and they don't seem to have a website??

Also, what's the big difference between the T and the GT series? What's the price differential for the different design?

[Damian]

The T turbos use a journal bearing and the GT series use ball bearings. Ball bearing turbos spool much faster than journal bearings and also provide better shaft support. They also have ceramic ball bearing turbos as well. The GT turbos are more expensive but are great turbos. Look at www.turbobygarrett.com and look at the differences. I really wanted a GT35 (I forget which exact model I wanted) but they are a but pricey. A GT35 is going to run around $1000-$1200.

Are you looking for an internal wastegate or external wastegate?

I don't know. What's the performance and cost difference?

Thanks for the info on the GT. vs. T.

[94cobra69ss396]

The current turbo has an internal waste gate.

The current turbo has an internal waste gate.

What's the thingy mabob on the outside of it? BOV? I know very slightly more than nothing about turbos.

Internal wastegate turbos are easier to install due to less piping to make up. External wastegates are actually better because you can size them up better to your setup (different flapper sizes), but it's more piping that has to be made up.

A good read for you that will make things make sense: http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech101.html

If it's on the turbo, that's your wastegate actuator. The BOV is actually on the intake piping.

I've been lazy. Thanks for the reminder to be diligent. Soon I'll be an internet expert giving questionable lectures on turbine blade geometry or some shit like that. :smack:

[Damian]

That's just turbo tech 101, just wait till you get to 102 and 103! I never made it past 102, or even finished it. Massive headache!

Well, if my OCD kicks in, all bets are off. :sm_laughing:
