Question for the high power track guys - I have done some searching but still not sure if I should move on to another turbo or keep what I have and have it re-sealed. I'm currently getting a lot of oil in my charge pipes and some smoking. Also down on power. Catch can is dry so no blow by.

I currently run a Turbonetics Stage III 60-1 HiFi, ceramic BB, stage III turbine wheel, 8cm hot side (purchased from SpeedForce).

Motor Mods: 2.7ltr (104 over bore) steel sleeved with J&E pistons, Pauter rods, stock cam, stock valves, stock head, (port matched), vitesse MAF/software, 83lb injectors, 3" exhaust no cat and 100 octane fuel.

Considering the Lindsey Super 65. Need a turbo that will support 400HP at 19PSI. I want a bolt on ready turbo. The Turbonetics was not so bolt on friendly. Required a bit of modification. Thanks in advance!

what tracks? what gears do you get in, get unto fifth or just fourth?

So Cal tracks. Autoclub Speedway, Willow Springs, Button Willow, Laguna Seca, Chuckwalla etc.
I hit 5th on a couple of tracks (Autoclub and Willow Springs. Mainly I need full boost by 3500 rpm. I don't want an "on / off turbo. The Turbonetics has a smooth linear feel to it but I'm wondering if something else would be a better more efficient choice.

Your biggest decision is efficiency / bolt on. I mean, having been in friend's cars with journal bearing turbo Vitesse Stage III it's easy to say just run one of these. On paper a Garrett turbo will have more recent technology in it but it's not bolt on.

Anyone running the Lindsey Super 65?

The super 65 is basically a GT40 compressor shoved into a T04E front cover. I think a compressor that large would be counterproductive if one didn't use a #10 hotside and at least a stage 5 wheel. You might see just shy of 60 lb/min out of it at reasonable track boost settings, should be good for 450+ rwhp and a really fast ride! You probably wont see much difference if you get it with the #8 housing and stage 3 wheel, but the #10 and stage 5/p trim wheel should rock your socks in comparison.

I really like the Kokeln stage V on the track car, which is comparable to the Super 61 of today. It makes 350 rwhp at 17psi with the MAF/chips/Mafterburner, head, etc, 348 torque. But we also don't go to any high speed tracks like Road Atlanta either - Hallet and TWS, Barber but those have been a while with the car down. Hope to remedy this by May.

Bret you planning on doing Mayfast??

well the question is will I have it back together and running by then? It's out and stripped down, if I didn't have to fly to Houston for a meeting tomorrow before going to work it would be rebuilt before I left of Wed. Going to try my best to make it...if they aren't full when I get it running.

Jim and I headed to pick up his 930 next time off, call you on that story.

I have a new option from Turbonetics featuring ceramic ball bearing and billet aluminum compressor wheel that will allow you to reach your power goals, while retaining a the smooth linear pull. However, it will require some modification due to the standard T3 exhaust housing. I will pm you with further information.

Vitesse stage 4. By far it'll be the best choice.

I run the Super65, not BB. It hits full boost at 3500, but it is realy very on/off. I have posted a boost chart in some other thread.
I am on a standard 2.5, so with a BB and 2,7 you should gain a few hundred rpm's.

I do some track days, and this turbo is not optimal for me. I want boost at 2800-3000, and more linear build. So i am going to a smaller BB. (or the vgt route )
But for fun, the Super65 ticks all the boxes. It realy is a fun and strong turbo. Oh, and it is realy bolt on. Just 5 min with a file and you are done.

Thanks for the replies. I have been emailing John at Vitesse and think I'm going to have him make me a turbo specific to my application. TBC....

I think that's a very good option. I have a Vitesse S2 on my stock 2.5 and I love it. You can't go wrong letting John do your homework for you.

Why are you thinking a custom turbo? The stage 4 was designed for a stroker?

I have the Vitesse St 3 and I love it. At the track I run significantly less boost than you though, 15 lbs. Turbo really comes into its own between 18-20 lbs.
