  1. Yeah I did before sending them off to be cleaned and flowed.. They are all 2.5 to 3 Ohms.
  2. Nothing has really changed with my setup though other then the injectors.. I have been running this setup fine for 6+ years with the supra 440cc mk3 injectors. MS1 has a 12 x12 table.
  3. I will post up on there .. I have never been on it before.. I cannot attach it.. Can I email it to you? PM me your email address if thats cool . Thanks!
  4. Thanks for your response!.. I have tried tuning non open loop and open loop.. both do the same hunting for AFR.. I looked at EGO control and I do not see anything that refers to PID. here is a screen shot as to what I see for EGO.
  5. Hey HybridZ ! I am running a L28ET with JE pistons nismo HG T3/t4 50 trim turbo .. Mega squirt 1 extra rev 029V with Tuner Studio MS v3.0.10 I used to run Supra Mk3 turbo 440CC injectors (low emp) and switched over to these Denso 19550-1350 RX7 NA 460CC injectors (low emp).. I sent them to be flowed and cleaned. They all tested good and actually flowed 492 @2.25 bar fuel pressure.. However when crusing the AFR is hunting and never really stabilizes.. I set the required fuel for 460CC and I played with the Injector open time and the PWM under required fuel. With the Supra injectors I had the open time at 1.2ms same as the PWM. It does not seem to matter much if I change it to 1.0 , 1.2 or 1.3ms with these .. I have searched and searched and cannot find the dead time for these Denso Rx7 injectors.. They are Pintle style and I think the Supras were (disk with multiple holes ) has anyone had any experience with running these Rx7 injectors and tuning with them? at 25% throttle and at WOT they seem to have stable AFR right at what I am tuning for. Thanks for any help!
  6. Ok, back on the road! Still not sure about the head gasket.. Thanks to Jonathan Taylor for helping me do the coolant pressure test.. We put 16psi in it and it really didnt go anywhere.. We did a leak down and every cyl was 10% leak down accept one.. Cly 5 was 20-25.. Not great but not terrible..
  7. Hot side of the IC pipe is almost done. Just need to clean it up and paint it. Hugh thanks to Mike at our local speed shop Top Dead Center for welding the pipe up for me so quickly! Just one step closer to getting her back on the road. Hot side welded up.
  8. So I got my Turbo back from being rebuilt!! woot woot! now to start putting her all back together! All the bad parts
  9. RESULTS! well at least bench results.. Soo I used a heat gun pointed at the bottom of the manifold before and after the gold heat tape.. I showed a slight difference in heat soak on the manifold.. It looks like it dropped only about 10 degrees. I was hoping for more but about what I expected.. However.. I did the same test with the gold reflective tape and my jet hot coated heat shield and that made a huge difference. about 20-30 deg cooler.. These tests are very far from being "scientific" but at least it showed me a very small sample. I think if you have the money, Jet Hot coating the whole manifold would do better then the gold heat tape and in combination with the heat shield would also help a lot. Ambient Temps; With out DEI reflect a gold DEI Reflect a gold Added Jet hot coated heat shield.
  10. I am thinking about ordering some and doing a heat test of the manifold.. Run a heat gun under the manifold acting like turbo heat and measure the heat soak.. Then put this stuff on and re measure.. thanks for the Info Tim..
  11. Turbo should be back this week.. Also upgrading to 550CC injectors and Champion Radiator.. Will post pics up soon.. Also thinking about re routing the IC piping under the motor to the passenger side and then forward to the IC.. Pipes should be no longer then what I currently have but feel it will clean up the engine bay a good bit.
  12. Thanks man.. Tokico springs with Tokico Illumina struts..
  13. So while everything is apart on my 77 280Z turbo, I was thinking about the DEI reflect-a-gold heat tape.. Was thinking about coating the bottom of the intake manifold as well as the runners and maybe even the IC pipe or fuel lines and rail.. I am running a T3/t04E 3" downpipe .. I have had this turbo setup for many years. I have a turbo blanket and the downpipe is wrapped with header wrap. Does anyone have any real world experience with this stuff? Their claims are pretty impressive if it actually is true. with the intake directly over the turbo, it should help with heat soak. https://www.summitracing.com/parts/dei-010396/overview/
  14. Up for sale her is a set of 6 Toyota supra MK3 440 cc injectors. I am upgrading and no longer need these. They have been sent to injector rehab to be fully cleaned and flow tested about a year ago. This cost 118.00 and they actually flow 456. Also comes with the Toyota injector clips. As for the rail they need a 11mm O ring style rail and can be made by Pallnet. Asking price is 150.00 obo. Located in Mobile AL.
  15. I bought it new back in 09.. I put a lot of hard miles on it.. I am going to send it back to the company I bought it from for a rebuild. I hope the compressor wheel is not chewed up too bad.. might have to replace it as well.
  16. Well, starting taking her apart and found that my turbo has in and out shaft play.. thrust bearing issues.. Soo now the turbo has to come off and sent off to be rebuilt.. uugh
  17. Wow man what a great build!! Went through it all! great job dude!! watching your youtube videos now heh..
  18. Thanks man! It has been down since Feb. I thought I had a HG issue but I think it is just a combination of water pump and I have a small leak in the radiator.. I should have the new radiator in a week and I should be back up and going here soon! I decided to stick with the S13 trans for now.. Maybe eventually I will be able to move up to the Z32 trans.
  19. Very very sad to hear this.. john C will be missed. Prayers to his family and friends. Wealth of knowledge he bestowed unto the Z community is great indeed. You sir will be truly missed but never forgotten.
  20. It has been quite a while since I posted on hybridZ.. good to be back.. 1- My Z is a 77 with a L28ET 2- Motor is a stock bore L28ET with JE pistons. I am running NA-a cam , ported intake manifold with the 65mm Weber TB and I ported ever living crap out of my exhaust manifold. 3- peak power was 385 to the wheels at 17-18psi and expect around 400 at 20psi 4- peak torque @ 390 to the wheels at same boost pressure and expect a little over at 20psi. 5- I am running Megasquirt 1 V3. 440CC MK3 supra injectors with a Pallnet fuel rail. Garrett T3/T4 50 trim turbo. 3" turbo back exhaust and 12X24X3 front mount Intercooler. Tial 38MM external gate. I modified the stock exhaust manifold and welded a uptube at the turbo collector to bring the gate to where I wanted it. 6- Porting the exhaust manifold helped the HP up top a good bit.. Also with the NA-A cam I am able to make power all the way to 6500 and still have plenty of power down low. I get 20psi right around 3Krpms, Port matching the exhaust housing of the turbo and the intake manifold helped as well..
