  1. Hi, Looking at you Adds as listed in the first post, to me it reads as Nissan parts. Maybe it's as simple as changing your add to read " will fit Nissan (whatever model)". or "suits Datsun". Just a thought. Wording of an add can change buyers perception. Hope you get it sorted. regards David.
  2. Building an L28 (NA)

    Hi, Just a thought. If you are getting a spark at the plug and fuel is present, Check that the valve adjustment is correct. If the valves are not closing all the way you will have a miss on that cylinder. If the valve clearances are correct do a compression test in that cylinder to see if you have a bent valve that is not closing all the way. David
  3. L28, Fitech Throttle Body Injection

    Hi Brent, Still haven't got around to firing mine up at the moment, but have some extra info for you. You have probably already onto this, but I will repeat it anyway for people not in the know. From FiTech: 1. The pressure regulator on the Fuel Command Centre (FCC) which the original instructions said to leave open on a normally aspirated engine is now recommended to connect to manifold pressure. This can be done at the Throttle Body or direct to the manifold. This lowers the fuel pressure when at idle and cruising conditions when high pressure is not required. 2. The PWM number is 75 which can be dropped to 40. This allows the computer to tune itself easier. Hope this helps. FiTech seems to be updating the system for easier use. Cheers David. (Enzo)
  4. L28, Fitech Throttle Body Injection

    Hi Brent, Same here. Looked at rotating the throttle body but it was in the "too hard basket". It didn't line up easily with the Arizona Z manifold. Probably a bit of overkill but with the alloy plate and extra phenolic spacer, I should have maximum shielding for the IAC. Also the back set of throttles don't seem to open the full 90 degrees. There is something in the installation paperwork about not adjusting the linkages as they are set at the factory.
  5. L28, Fitech Throttle Body Injection

    Hi Brent, I spoke to you recently on Auszcar about your installation. I have attached a picture of what I have done regarding the heat from the headers. I haven't included a picture of a thin stainless steel plate attached to the manifold bolts in the middle section where you have the excess heat wrapping but that is my first shield. Then is the alloy plate over the inlet manifold. Then a White Phenolic plate at 6mm which can be seen that goes back towards the valve cover. The throttle body is then placed on top. Gaskets are between the manifold and alloy plate/ phenolic plate/ throttle body. This allows a small air gap between plates. This should give maximum protection for the electrics on the back of the throttlebody from heat off the headers. Also the studs have been replaced with longer ones for the extra thickness. Regards David
  6. Mystery hesitation under load, worsens over time

    Hi Mate, Check out the rubber diaphragm in the mechanical pump. If it has a small split it will still supply fuel at low rpms but get worse as you drive. As the split get bigger fuel starvation will get worse. Also check you oil and see if it smells of fuel. Regards David.
  7. 5spd front cover lip seal

    Opps!!! I stand corrected. Newzed is spot on. My brain wasn't switched on. ( I could say being from a land down under that I was looking at everything in reverse).LOL. I will delete my first confusing post. David.

    Hi, First picture. Listen to NewZed, he is correct.
  9. Why L28 Piston Deck Height?

    Interesting question. I recently installed an F54 block with a P90 head in my 260z. The engine had been rebuilt by the previous owner some years ago but had been stored. I wanted higher compression so I replaced the P90 with a refurbished N42 head. While the head was off I noted that the Flat-top P79 pistons were sitting above the deck but I didn't measure the height. (Looked to be only just above. I'm guessing 20thou). Felpro gasket installed. Once assembled the cylinder compression with some oil added to the dry cylinders was between 220-225 psi across the cylinders. Higher than I expected. Lucky in Australia we have 98 Ron fuel.
  10. 1973 240Z, L24 questions

    Hi Jamie, I misspelt the Business name (Mangoletsi) . If you go to the where to buy section all UK and worldwide distributors are listed. Have a talk to the guys at Jenvey and tell them your plans for the engine and get there recommendations. If I lived in the UK I would buy the Mangoletsi manifold and get the Jenvey boys to set up the throttle bodies and linkages for me. I would definitely go with the Heritage series so I could have the old school carby look with EFI technology. I have a 2.9 litre L28 with all Datsun Spirit and Kameari components waiting to be assembled when the head is completed and this is the way I will be going for that engine. For simplicity on my existing engine which is a L28 with flattop pistons and a N42 head with 72 degree camshaft I have an Arizona Z 4 barrel manifold and FiTech throttle body with The FiTech fuel command centre suppling the fuel. Talk to Datsun people and get a firm idea of the direction you want to go with the engine and car and work out your budget before making any major purchases. Good luck David.

    Hi Jamie, Since you are already in the UK check out Mangolestri for a Datsun manifold and Jenvey for Throttle bodies. If you want your car to look old school, look at Jenvey's Heritage injection setup. They have throttle bodies in specially cast cases that look like Weber DCOE carbs. You get the old school carb look, but all the internals are EFI. David
  12. Another Vela Rossa install

    Hi Dan, Great work and looking good. You have a lot more patience than I have got. It's good to see another car with the rear side windows left in. It does give better vision and I think it suits the lines of the car. Call it an optical allusion, but I think it makes the car look longer and leaner than having the fibreglass covering the side window. I did mine back in 2004. Keep up the good work. Regards David
  13. RIP John Coffey (johnc)

    RIP John. A genuine nice guy and wealth of knowledge has passed to a better place. Our thoughts are with his family. David.
  14. RebekahsZ is right about checking the tires first. I had fitted some 245/45/16 tires to my '76 260z on 16x8 BBS wheels and found that they tram tracked on every uneven section of the road. The tire shape was more of a sharp angle at the edges with a large footprint. On changing to a 225/50/16 profile tire which had more of a rounded edge to the footprint, it was like driving a different car. For a street car the narrower tire worked out better. For a race car on smooth tracks and without the suspension travel of a street car (which would be on all sorts of rough roads), you can obviously get away with wider tires. As to modifying the cross member or adding Bump steer spacers, well that is up to the individual. All the best for the New Year. David (Enzo)
  15. Hello Guys, Merry Christmas from Australia. I am getting a head heavily modified at the moment with Argon welded chambers, etc to go with a bottom end with all Datsun spirit parts. The original head was warped so I purchased a replacement head. When I was discussing the modification with the engineer he mentioned about pre-bending the head prior to commencing the work. I asked him if the head being warped was an issue. He replied that if it hadn't been cooked beyond repair and softening the alloy it would be ok for the modifications. As it worked out the warped head was ok to use with the benefit of being pre-bent and I got to keep a spare good head. Have a safe Christmas and new Year. David (Enzo)
