also in that 70's show there was a silver z in the background at the drive in.

I went with a four wire off a thunderbird, but if you're going new just go to autozone (or any other place you can get parts cheap) and get a universal 4 wire (or 3 wire if you must) from bosch (or ngk). Here's a link to the thread I posted about finding out which wires go where. http://forums.hybridz.org/showthread.php?t=124853&highlight=o2+sensor

Ron I'm just curious as to how you are calculating those diameters/torque peak relations. I would like to know what changes these numbers, and how does it apply to ITB setups vs. plenum setups.

2000-2003 suzuki gsxr 750 and possibly 1000. 600 will work as well, but they are smaller (38mm), and bulkier looking.

yamaha does. on the 2007 r1 but they are not infinitely variable

On a dcoe the spacing is 90mm... so If i got a cannon, or equivalent manifold, I would have to space every single throttle body. Then I have to deal with the fuel rail in between each throttle body or go totally custom. BUT the main reason I'm going with this setup is because these throttle bodies mount with rubber boots, just seems a little easier. The spacing on these is 80mm, and the less I have to deal with spacing them out the better. The fuel system could be hooked up the way they are setup right now and the linkage works... just a few less things to worry about. Although, 90mm would allow a slightly wider velocity stack and more filter options. I'm running MSNSE so staged injection would not be a problem. I like to keep things simple, so if i can get away with only 6 injectors I'd be happier.

I've been following the honda guys with their motorcycle itb's for well over a year now... and with a little extra money I made from some ebay sales, I started acquiring parts. Heres what I have so far: Heres an idea of what the manifold is going to look like: In case anyone is wondering, these things stack like legos. The linkages and all. to get to my final design I'm just going to put a spacer in the middle and extend the linkage. I'm also planning on making some fiberglass Velocity stacks that will require nothing other than a hose clamp to attach to the outside of the throttle body. The next step is to decide on a runner diameter and find somone to TIG up the runners to the flange. I haven't decided if i'm going to run 12 injectors or plug up the flange holes. Thanks 1 fast z for the quick shipping! -Oliver

chassisshop.com has a bracket that will do just what you want, you just have to make your own links.

I wonder if that last suspension is designed to use a pull type bellcrank setup for the shock/spring. Doesn't look like they left much room for a pushrod the way the upper control arm is made.

sounds like a government regulation in play. kinda like why your speedo only goes up to 85mph

i drive mine everyday... I got some fumes, but hearing my slightly hopped up l28 lope at idle makes it all worth it for me. No (insert disposable car here) can do that.

I'm confused... you're trying to replicate a guitar you already own?

gsxr 600? Heres a hint: 2001-2003 gsxr 750 had 42mm TB's, and the same year gsxr 600 had 38mm (which I think you are refering to). Both had 240cc/min injectors. And Both are independently cast. both 600 and 750 (and 1000) are held together by three long rods with nuts at each end with 80mm spacing. Basically you could splice the center two TB's into the other set of four TB's and have 6 itb's with 80mm spacing. The spacing between 1-2 and 5-6 intake ports is something like 50mm or so, so you will have to angle out, because the gsxr TB's can't really be smushed together without any significant amount of machining and redesigning of the linkage. oh no... i've given myself away...

uhhh.. aren't you a field engineer!!!!???? I guess you guys use the 'merican system in the field anyway.

I'm no specialist on the subject, but since the cams interchange, and the cam spacing is the same, I would have to guess that the valve spacing is the same.

I have a 272/282 split cam with .480" lift (12.192mm) and I want to go bigger. This is on a street driven 280z with n42 head and flat top pistons.

Why did you form the metal with the bends instead of the way the cardboard was mocked up?

did you speed up the playback rate? I'm looking at that cyclist you passed and he must have been spinning a 150rpm cadence... ( i guess it could have been uphill)

Believe it or not, I read that article before posting this question. The article revolves around an engine with "high" and "low" injectors. In my case I am going to be running "medium" injectors... where the injectors are neither right behind the intake valve nor right behind the throttle valve, but rather right in front of the throttle valve. After reading Tony's post, I have been convinced that i will have no problem running the injectors right in front of the throttle. edit... wording was wrong....

I want to go with an ITB setup, but I'm thinking about drivability. The throttles i'm going with have the injector in them, but for convenience I'd like to have them further away from the head (less angle on the runners). So there is going to be a limit here: Too close too the head = bad runner angles, better driveability Far away from the head = great runner angles (almost straight) but loss in driveability. (more homogenous fuel air mixture) I'm trying to avoid adding a second set of injectors close to the head. Seeing the accurate injection setup it looks like it places the injectors about 5" from the head (maybe more with a cannon manifold) and i'm wondering how streetable this is, at idle and low speeds, for example.

That's awesome. The cage looks great, can't wait to see the primered pics. Put some clothes on her!

the 993 had 11qts and 2 oil filters

wow. Ok who's going to do it for the L-series??!? Cast a DOHC head while they're at it

Is that a pvc intake elbow mounted right on the turbo?

also, Building on the atm machine one, TPS Sensor ...ok thats all i can think of.
