Pettit turbos
Just got my turbo from Pettit. For those interested in keeping the sequential twin turbo, but increasing the output, this may be for you. Their advertized unit is the hi-flo turbo blueprinted, with ported and radiused interior passages and ceramic coating over the interior hot spots. Usually this unit is a rebuilt unit (your core or theirs) for $3500. Due to a scarcity of good rebuildable cores without cracks, they have had to start with a NEW Mazda stock turbo. Price is the same, but now they start with a new unit. Workmanship by Cam is excellent- the interior is smooth as a baby's bottom and larger bore, with no abrupt angles anywhere visable. Cam claims the ceramic coating will substantially add to the durability of the turbo, especially for those who increase the boost above stock. It gets put on this Tuesday. Can hardly wait to get my current oil leaking unit off. Am eagerly waiting to see what new 0-60, 1/4 mile times will be and if I get time- new dyno numbers. If this works out, I'll need to talk my wife into another side-by-side FD vs Z06 adventure. Zoom Zoom.

Hell yeah, I'd like to know how those stock sequential twin upgrades workout. I'm thinking of doing that for my car, but for $3500, there's other things that I should be spending my money on for reliability mods since my turbos are still in good running condition. Ball bearings and ceramic coating....mmm, smooth. Let me know how it runs.
your wife drives a ZO6? That's hardcore, man!

You paid $3500 for Pettit turbos? Ouch. I hope you like them. I heard they flow about 15% more than stock so you'll get maybe 15-20 rwhp - atleast they are new. For that money I would have fone T04E or S - much better reliability with watercooling. And with that kit - your wife would be way back in her 02 Z06

Can you run a single turbo with the stock system at low PSI while you raise cash for fuel, ecu, etc upgrade?

1) my income isn't high enough to pop for them all at the same time
2) the sequential system gives too many problems...so i was wondering if i can get a single turbo and run low boost (like 5 psi) controlled with a boost controller, until i raise more money and get the rest. It's for reliability only, that's the only reason i want the single for now until i tap into it for it's real potential

The Pettit turbo is a little pricey, but mainly cause they have to start with a new factory turbo, instead of a rebuilable core. Did not want a single turbo, since I wanted to keep the low end power that the twin provides. I have enough mods to support the single, if the mood ever strikes me, but I was getting pretty good output with the stock twins at 15 psi.

Hey Ken, how are you liking T04E? Is that the street racing one? And how much did you pay for the whole kit? Jeff at Rotary Power said he'll charge me 600 for installation

i dont think anyone should say that the turbos are pricey to the guy above. im sure he paid for them with the cash in his pocket. no offense im not *******, we all wish were in teh same situation. ZO6 vette, rx7 with new turbos, truck, etc... toys...does it get any better than that. let her drive teh vette its under warranty, but the 7, dont even think twice about saying NO..................

Let's see. I have Pettit's hi flow turbos and for awhile I was using Pettit's computer with them, hhmm no standalone computer there, just an upgraded one. Fuel pump? Nope, just the stock one. 1300cc injectors? Guess again, still stock. Intercooler? Hhmm, stock too. At 13 lbs of boost it's still pretty rich too. Detonation? No sign of it at all. Makes plenty of power too. Will I go single one day? Probably, but there's things other than my RX that need my money. I'm also running them because Cam told me to run them. Now I don't think he'd tell me to run them if it didn't fit my setup.
Now for anyone thinking of getting them, my recommendation is to get them. They do make very good power and it's definetely noticable. They do seem to spool up a little quicker than stock, and make more power and torque at a lower RPM than stock too.

single not reliable?? It's a heck of a lot more reliable than the rat's nest sequential system. That's the reason I went non-sequential to make it more reliable and that's added more power - no solenoids, actuators, rack, and about 70 less vacuum lines
- full boost by 3200 rpms. A TO4e gets full boost by around 3500 rpms - not bad and yes, if it's tuned right it is much more reliable than the stock twins and cheaper to fix if a problem arises.
