I have similar mirrors sitting on the roof of my car waiting to go on. Can't really tell you yet, except that I am going to try it too!

SWEEEEEEET! Can't wait to see more scottie.

Yeah the japanese automakers (or maybe it was the government) made it so no car could clain more than 276hp from the factory. I'm not 100% sure why. That said, the 3200lbs 276hp R34 Skyline GTR keeps up fine with the 3700lbs 386hp Audi RS4. (both AWD) You do the math!

Heh, my favorite doggie!

Yes, check out my webpage. At the end of the tech article/FAQ are a couple links to other really good turbo sites.

Take off your windshield cowling, and take a look underneath. I know a guy who put his in there, totally stealth. I wish I had seen that before I put mine in, because I would have copied him. I put mine next to the alternator on the L6, on the inner fender. (about 1/4" away from the lower rad hose)

Uh guys, he's not running a turbo...

You know John, by the end of the day you aren't going to have any secrets left.

Hey dude, if anyone can help you its this group! You've started well by asking questions and trying to find out more about this swap... However, its my opinion that unless you have about $20,000 to spend, OR 5 years to do this kind of swap, its just not going to happen. Maybe I'm considering this too much from an engineering perspective, (go figure) but we are basically talking about designing a new drivetrain for the Z from the ground up. Suspension, brakes, steering, and driveline all would have to be redone. I'm currently in a group of 4 people that are designing the suspension for our FSAE race car. The 4 of us spent 900 man hours on the suspension alone just to be happy with it. And we were lucky enough to not have to build to any preset specs, such as driveline types, specific wheels, etc. Now tht said we were 4 engineering students, and engineers are notorious for over analyzing and over building stuff. Not trying to dissuade you from this, I just want to make sure you get a picture of what your in store for before you go nuts building it.

John yuo can't really compare lap times between the series. Nascar has a weight requirement of something like 3400lbs min. (I think) F1/CART are both a LOT less. (like half that)

I'd like to echo pete's statements. Thanks for posting John! I learned a heck of a lot from those posts.

I've had terrible luck with UPS and really good luck with USPS. You save a bunch of dough having it sent USPS as you don't pay all the duties and taxes that you would through UPS coming into canada. Sounds good dude! Glad to see you back here. Hopefully soon I'll send you some updated pictures of Goldie.

Sean I think what Ross is saying is that resonators themselves are usually fairly flow restrictive. You'd likely be better off with a high flow muffler instead of a resonator, but in the tranny tunnel. I would certainly expect that 2 high flow mufflers, 1 in the tranny tunnel, 1 in the stock location should suffice. But if you like it a little throaty, I would try just the 1 in the tunnel first. FYI, I had a 2.5" exhaust, with just a straight through muffler in the stock location on one of my L24 powered cars. It resonated a bit, and so on, but I drove it for ~25 hours in a day and a half and survived in a 240z with no carpet or sound deadening. The same setup with the muffler in the tunnel instead of the stock location probably would have been that much more bearable, and with the zx you'll likely have a bit more sound deadening as well, so you'll be fine IMHO.

Not much for me to add, except for if you have a L6 why would you want to make it sound like a V8!!! IMHO (very humble) the only thing that tops an inline 6 for sweet exhaust note is a V12. Don't get me wrong, the V8 sounds AWESOME, but its a different type of awesome. Its kind of like comparing a tiger growling to a pack of dogs barking. If you are mostly stock a 2.25" system should do you nicely. I would recommend getting a single muffler that flows well and putting it as close to the engine as possible, then running a straight pipe after that. (in the trans tunnel is a good spot) This will dampen the resonance typical at 2500rpm, and still leave good flow. If you find thats still too loud just add on another straight through (high flow) muffler in the stock position as well. Best sounding exhaust next to a ferrari I've heard was a friends BMW 323i with this setup, except his car had dual 3 cylinder headers (on an inline 6) and true 1 7/8" duals all the way back. 9.8:1 compression at 7,000rpm sounds awesome!

Yeah we're pretty lucky in North America when it comes to cars. I remember my time in Denmark thinking 'where are all the old cars?' You just don't see them there. The I found out how difficult it is to keep anything over about 10 years old on the road due to government legislation. No thanks! That said, there are a lot of good things about Scandinavia as well. More good than bad!

Hey Jens, where in Denmark are you from? I spent about 6 months in Aarhus a couple years ago. My Danish is a little rusty however.

Just a small correction. Nearly every after market efi system will operate variable valve timing. (at least I know the SDS, haltech, etc will)

Went for a drive in an Audi S4 last week. It was scary fast. Gobs of power anywhere from 1500rpm to redline. Not a hint of lag. Not bad from a small 2.7L twin turbo. Its amazing how may misconceptions about turbo engines still float around, my guess is that they are from people that did the early experiments with a draw through system, which is decidedly very primative as turbo's go. A properly setup turbo system can have no noticable lag, and produce gobs of torque even at low RPMs while still maintaining high rpm performance.

Trying to think about this with an open mind, however I can't see the marginal gain running only 2 psi really being worth the effort. Likely you'd get similar gains by advancing the timing and running higher octane gasoline. Not to say that it can't be done, but how much easier is it to install this system than a full blown turbo system?

A t3/t04 should bolt to the stock zxt exhaust manifold, as it uses a t3 exhaust flange. As for the additions, it depends on your fabrication skills. An external wastegate or an intercooler would probably be about the same amount of work, requiring some new piping, etc. Personally I wouldn't screw around with the stock system/wiring/sensors. I'm using stock injectors with a few other cheap mods and an SDS. I'd say the whole setup could be copied for around $1500canadian. (SDS, fuel pump, injectors, etc... my whole engine was $300 from a wreckers) Like Mike said, throwing $500 or more at the stock system might make sense at first, but I think once you really get into it you'll enjoy the fact that you can tune the car easily for any mod you want to make.

Davy, you need to get a Z-car dude!!!!!!!!!

Uh, I don't think we need to see pictures of your boogers, no matter what colour they are. Oh, hey, did you mean the polishing?

Just one point of clarification to an otherwise excellent post: If you work with aluminum dust a lot, your boogers will turn green, not black. Black is the result from carbide dust.

Jamie, if money is (relatively) no object go for it by all means. The one to really talk to is 240Z Turbo since he is running a 3.0L turbo. I believe that even more than the increase in displacement, the ability to get a really good rod/stroke ratio and therefore help prevent detonation is the selling point on this one. I think 240Z Turbo is running 8.5:1 CR at 15-18psi boost. (off the top of my head) Some serious torque available there! (he uses a 4200 stall too IIRC )
