  1. I bought one of those Chinese exhaust manifold for turbo. The turbo T3 or T25 will fit but way too small for this car if using single turbo setup. My Turbocharger Garrett T72 will not fit and will hit the valve cover. No way ...No how. First thing I did was cut the exhaust manifold T4 turbo flange. Then I bought a square stainless tubing 2" x 2" 1/8 gauge. Then I cut 2 pieces with the angle of 35 degrees. I cut the middle of the square pipe. I took the middle section plate and I used it to divide the port Then I eyeballed the gasket and see how my mod looks I tacked weld the flange and tacked it to the exhaust manifold Then I mounted the T72 turbo --- it looks ok though.....nothing fancy NEXT IS MODIFYING THE WASTEGATE PIPE. THAT PIPE IS NO GOOD TOO. THE PIPE RUNNER IS LOWER THAN THE COLLECTOR FOR SURE IT WILL BOOST CREEP.
  2. I've been starting to do some work on my 280z Rb26 swap. Many years ago I bought one of these Chinese turbo exhaust manifold. http://tinyurl.com/myfnv5h I thought it will fit to the Z. I mounted it and found out my T04 T76 turbo will not fit. If I sit the T4 turbo, the turbine & compressor housing will hit the valve cover. This manifold has to be modified. My question is, is there anyone here able to modify this turbo exhaust manifold to work ? thank u
  3. I'm ready to tackle a big job. My 1977 Z was been in the bin for many years now. Three weeks ago, I moved the Z in my garage and started the process. I installed the engine and the transmission (Rb26 mated to Rb25 tranny). It's in ! I have a question in regards to the engine wiring harness. I completely removed my stock 280z engine wiring harness except the accessory wiring (lights-instruments-signal and so on) 1. I have an Rb26 engine harness, I spoke to wiring specialties - they told me that it's better for me to start a new wiring (made by them) to ease the process. I'm trying to save some money 'cause the wiring specialties cost $495. and I already spent $250. on the Rb26 harness. Can someone give me a feedback in regards to the harness? Can I make the stock RB26 harness works in my 1977 z? 2. I rebuild the engine but in stock form (piston-rods) are stock. My injectors are stock - how much power the stock injector can handle? I have no problem buying a 750cc or 800cc injector if I need to. 3. I will use a single turbo setup (Garrett T-72) & I bought an apexi powerFC. My rear end still the stock R200 but with QUAIFE ATB, will the R200 can support 350 & up hp ? I appreciate any help on this project....thank you
  4. Ok, I will buy the L-jetro (MAF) 'cause it's cheaper and can do the same function. I plan to use a much bigger airflo meter like the Q45, is there adjustment value on the L-jetro in regards to mapping using a bigger meter like the Q45 vs the stock RB26 airflo meter?
  5. Which is easy to tune? D-jetro or L-jetro ?
  6. I have two questions: Anyone has experience using Apexi PowerFC for Rb26dett? I have a AEM EMS on my Lotus Seven(powered Honda s2000 supercharged) and I like it but they are pricey. I have a chance to purchase an Apexi in cheaper price but I have no knowledge on this standalone. Can someone give a little feedback on this? Also.. is there a code in the block to differenciate if my engine is R32/R33 (I know it's not R34)? Thanks
  7. The last time, I remember modifying my oil pump sump pickup....but I'm not comfortable i did it right. Is there any aftermarket that you know selling an oil pick up for RB26? I also forgot where my oil sump came from but it fits...all i need is the proper pick up.
  8. Oh, that's good news, I will talk to them. What they do? modify the R32 harness and plug it to stock 280z harness? Thanks stony
  9. I want to make my life easier and perhaps buy an AEM EMS? - I don't know i'm not certain yet what to do in regards to the wiring....what do you suggest? I just finished my Lotus super 7 project and now ready to the next one.
  10. I wanna go back to continue my 1977 ZapZ project with RB26 engine and Rb25 tranny. I forgot what i need to do in regards to the wiring. I have the stock 280z wiring in the chassis and I also have an RB26dett R32 engine/injection wiring harness. Where do I start? Is there anyone one can help me convert/merge my stock 280Z wiring along with the Rb26 wiring? I will pay. I stopped this project for about 3 years now. I'm ready to continue. I forgot all my plans & things that I need to do. That's a long years that the car sitting.....empty heart. Thank you...
  11. Too bad, I wished I bought the wiring from you. Can you PM and give me the price anyway? thanks
  12. My F20c is done! Oh, not in my 280Z but in my Lotus 7, 9K rpm weight 900lbs --- not turbo but currently i'm installing a rotrex supercharger http://imageshack.us/photo/my-images/203/supercar10.jpg/ http://imageshack.us/photo/my-images/59/may172010013.jpg/
  13. I have a 1977 Z with RB26 engine and Rb25 tranny. Due to some medical issue, I kept this project aside for many years. I lost interest but I'm rebounding back. I think working with this car again will be a great therapy for me. I have an old electromotive ignition and fuel injection system. I don't have a plan to use this system. I plan of using AEM EMS and a stock wiring came from Skyline. However, I don't know if my engine is R32 or R33. The engine is 1998 and did not come with FI injection wiring. Someone is selling me an R33 FI wiring. If my engine is R32, is the R33 wiring will work on the AEM EMS? Oh! can someone tell me too if 1998 is R32 or R33? Thank you

    Base maps

    550 injectors and T76 single turbo. Can I read your latest base maps? I'm not too sure on a bunch of parameters. Yes, I know I can get the base map but there are parameters I need to understand. Will you share me your config?

    Base maps

    I'm in the process of putting back my Z and firing my Rb26dett engine. Is there anybody here kind enough to give me a hand? Is there anyway you can share a base map for electromotive. I know every car is different. If I have a base map, at least I can continue my quest to an uphill tuning battle. Please?
