My main concerns were price and availabilty, I got a set of leather 88 300zxt seats with power everthing, they look pretty nice too . I would rather have MR2 or Corrado seats but I can never find those cars in our small junk yards . I got mine for $100 cdn for the pair, and have to fix the drivers seat . The drivers seat is real heavy like 60 pounds plus . Paying for shipping on a seat to Canada is way too expensive . I think this adds to enjoyment of the car, so I take the weight penalty .

Yes that will work, and with factory emmisions is #1, economy next, power third . On the 280z(x) non turbo the igntion advance is not set by ECU . An air fuel ratio meter with O2 sensor bung might be a good thing to try and set the right ratios .

Other seats I like are Toyota MR2 and VW Corrodo seats very nice .

Just to let you guys know that my brother has a RAM clutch in his talon AWD. I was not to impressed with it, it is an on/off button with no slipping allowed . The pressure plate was a stock one, and had very thin friction material . It chatters once and a while too after hard driving . Not very impressed, IMHO I think CFDF is worth the extra $$.

Yes I have heard about the jump around sampling and updating . But hey it's better than a poke in the eye . Smart tuning proceedures, and some dyno time should keep me out of hot water .

I think the Z is quite sensitive to this, used to happen when I drove my car in the winter for a few years . It was very pronounced on ice and ruts, 5 psi made a huge difference .

I am a little fuzzy on the Miata one whether it was stock or aftermarket ECU ( think it was stock) . Anyhow the DFI situation isn't as bad as it seems, not optimal but will be very useful . Once the major tuning is done I doubt I will need more than 6 variables at a time anyway . I will logs up with RPM, O2, MAP, TPS, Air Temp, Total PW . From there a charts will be made, the key here is to plot one variable vs time and don't try and mess with scaling . Then I will put some text boxes and arrows to scroll through the graphs . It will take some time to set this up but once done will be very useful . The setup will be very simular to what Scottie has posted . Only trouble is I have to switch to Excel from DFI software .

The Miata guys had a real nice one for a palm pilot that does there datalogging . It was super slick and had a good sampling rate . My programming skills are limited to visual basic, so a conversion from DFI to Excel format will probably be down the road .

60-1 you will definately want an external wastegate . TimZ had the cleanest install I have seen with minimum hassle, as well as optimal performance . Search those archives, he gives all the details . Make sure to verify the A/R ratio on that monsta turbo . You may want to step down to mabey a .63 or mabey even .42 ratio . A little known fact is with a big external wastegate you can have a lower A/R ratio than normal to get turbo spooled up quickly, then dump the extra gas without a big pressure drop at high rpm and load .

This might be a bit easier unplug TPS and take it for a spin . If it runs just as bad and doesn't get anyworse, chances are you have a break in your TPS wiring .

When I was looking at the graph I "ASSumed" that the 749mv was max and Omv was min . Then I looked at were the launch speed was 0 . Just before launch I thought that the O2 voltage was below 500mv . This would indicate a lean mixture, a shot in the dark . Good to see you straightend things out . A good datalogger is a nice thing to have, to bad my DFI log is so mickey mouse !!

I think Scottie likes looking at the graphs almost as much as racing . I like the numbers as well . I was just looking over the charts trying to see if I could spot anything wrong . It looks like the car is tuned very well from info given . The one thing I noticed with the launch is that O2 voltage is below .5 mv when at the lights . Could this be why it is not getting enough rpms with the transbrake ?? Probably need a graph of the MAP sensor . Good luck tracking the problem down .

Easy way to check a slipping clutch on a turbo car go 60mph in 4th or 5th then tromp gas . The car makes max boost in these gears and with the high speed aerodynamics it is hard to push the car . End result is the engine rpm will noticabley rocket up without much increase in speed .

If I had to guess I would start with the charging system . Since other electrical components have been acting up . If the ECU doesn't have proper voltage then EFI will not run correctly . TPS sensor is a 0ohms-High restance it should be linear . An engine analyser may be cheaper than replacing parts at random .

I believe the sensor is 3/8"NPT for a standard GM sensor . Nice to hear you are pleased with your purchase, just wait until that puppy runs . Mine may run sometime soon, got a chance to work on mine on the weekend .

I did not have the $$ to buy a set of the CV adapters But I would like to thank Scottie for coming up with something great and sharing with everyone . His prices are very cheap, and top quality !! I can see quite a few custom parts flying around this site, making the Z cars better than ever !! Hmm SCCA for brakes, Scottie for CV adapters, custom control arms Mikelly . I can't believe the amount of customizing that has taken place and shared on this board in the last year. The R&D on this site far exceeds any Z specialist company .

Very nice I wanted to get Konig Villans a while ago, no luck . The mustang ones look even better . Very tastefull !!

Good discussion, I hope I didn't come off the wrong way to anybody not my intent . Excellent diagram I know exactly what you are driving at . Won't the front hinge be less likely to flex with the rocker box tube connected at the bottom of 1 . Yes I do agree that it placed in the middle of the door will be way better . But this is unacceptable for my street car, I am 6'1" and 190 lbs . I may be grasping at straws, mabey a 4 point is all that is needed .

Yes it will be street driven car 80% of the time, I will drive it every day of the week (enjoying every second). It is in Canada so I don't think driving with a roll bar will be a problem . Still undecided on how far I want to go with my cage .

I am a little new at the whole roll cage setup, so I am no authority on this . However I do know some basics Any cage is better than none, unless it has a bar that can hurt the driver in a crash . The car will be used everday and have people in the back once and a while . Given that the car is unibody, just about anything will benifit to chassis stiffness . I think the rocker tube will keep a square car from turning into a rhombus under hard cornering forces . The door bar is nessary to provide a gusset for the main hoop . It will keep the main hoop from delfecting in case of a roll over .

Just thinking out loud here but when I was doing some frame repair, I noticed that the rocker panel box has a bit of room in it . Mabey you could have the bar run right by the seat tying in front to rear . Might even be able to sneak the carpet right over it with a small bulge . I am double pooched by having a 2+2, I will need a cage and acces to rear seats . I don't care if mines legal, just want some added safety .

Lots of people when building an engine don't consider it as a package that must be built for a specific price, purpose, power, rpm . For example a tunnel ram intake on a stock 350 with dual carbs sux for power and gas milage . I would have loved to see the look on that vette owners face . A small dose of reality to his fantasy world

One thing about all-wheel drive cars is they don't need the power to weight ratios like the RWD cars . They have a huge launch advantage giving the impressive 0-60 times . That is if you drive it like you hate it . I think the fuel delivery issue is what stops most people from going turbo . You just can't slap on a rising rate FPR onto stock EFI and expect a turbo to run as good as the supercharger . A new fuel map must be done, it takes more R&D for a turbo . In the end it's worth it though .

Alright for a chevy nova, but I think just a plain old LSD would better suit the car . Most people, many people don't realize how fast they take corners in the Z, until the get in a different vehicle . People who follow me are like " You really whizzed through that corner!!" Hmm I don't remember driving that fast . The powertraxx is definataley better than a locker or going with a welded diff .

Hmm it sure seems good that SportZ magazine is out find the good articles . Congratulations on being published, a big pat on the back .
