I re-entered the Z-World last summer after 20-years away (had a couple 280ZX Turbos in the distant past). First thing I started doing when I got my car was spending hours each day in this forum learning everything I could. Well, 8-months later my engine mods are done. So, I thought I would post my build details along with the dyno sheet.

Thanks to everyone who posted, replied and helped along the way!





Here's what I did to my 2004 Roadster:

• Turbonetics Single Turbo Tuner Kit/ Intercooler
• AAM Spec 1 Fuel Return System
• AAM Spec Angled Intake Plenum Spacer
• AAM Spec Oil Pan Spacer w/ Line Kit
• NGK One-Step Colder Plugs
• Turbo XS UTEC Engine Management
• TurboXS UTEC MAP (Manifold Absolute Pressure) Sensor
• TurboXS Tuner Reg
• Walbro 255LPH Fuel Pump
• RC 440cc Injectors
• JWT Aluminum Fly Wheel
• JWT Heavy Duty Clutch
• NISMO Cat-Back Exhaust
  • Test Pipe
• Greddy SMI Meters
  • SMI Integrate Controller
  • Boost Meter
  • EGT Meter
  • Fuel Pressure
• BBS RGR Wheels – Diamond Black Painted
  • 18x8.5 Front
  • 18x10 Rear
• Michelin Pilot Sport Tires
  • 225/45ZR18 Front

Thanks again. This is a great forum!

Great stuff!!! Congrats!!!

 

Impressive mod list you have going on there. I bet you are loving the big single. Congrats.

 

humm...... I have the same basic setup but with the vortech sc. I tought that the turbonetics is soppose to make more power than the vortech? I get 400whp @ 9psi. but you get power earlier witch is expected.

 

I think it may be that I am only boosting to 8psi (even though the graph looks higher). Also, it will depend on the dyno used.

Either way, I would guess we're both having a blast with our FI Z's...

Cheers,

Mark

 

depends on the dynos too... i would not compare there...

 

Congrats on the turbo kit install.

I'm interested as to why you're making boost so late (well past 4k rpms). Just saying because my setup made 9psi well before 3500rpms.

 

i had that same question..i hit full boost 3.6k avg

 

Don't know the answer. I'll ask my tuner when I see him tomorrow.

Thanks!

 

hahah there is probably "not going to be a good answer" there lol.... i dunno... they might be pulling too much timing
you might be able to squeeze a lil more powere there...just dont mess with the rev limiter

 

So, the answer is... That dyno sheet is a HP Run. The boost actually does come on much higher under driving conditions. I looked at all 20 dyno sheets at my tuner's place yesterday and under normal acceleration the boost is there much earlier (in the mid-2000's as stated).

One thing for sure, you feel it in the seat when the boost comes on! A whole new car.

Thanks for scaring me... LOL.

 

Sweet, welcome to the world of FI And yeah I'm at full boost by ~3500 rpms

 

Thanks! My boost goes positive at 2250rpm and am at full boost at 3500.
