  1. the cheaper is to build your own multi layer copper head gasket , what i did , removable and no leak if well done . custom pistons ? after market pistons exist , some times need over boring the rod at the pin
  2. 89 mm with F54 would be rather safe , but not with P30 or other blocks my P30 from l26 was in the water at 89 mm , sleeves to come i did not sonic test my f54, i think for NA it's enough
  3. my F54 is bored to 90 mm , stock rods but much work on them, no problem for a NA engine , megasquirt injection and timing
  4. front cover without water pump
  5. The timing cover was removed and changed for a custom made in billet alloy I dont Know the power
  6. Hi, Already done years ago : 6 holes above exhaust pipes, and one big tube feeding water in reverse flow with an australian electric water pump Davis Craig. Absolutely no problem of over warming there are two little purging hoses in the upper roof of the head , for avoiding eventually steam , returning to the expansion tank excuse my bad english in my explanations Regards Didier PS : Peter Macdonnel built an amazing system like this on the Green Hornet , but no reverse flow
  7. The one and unique thing to Know is the total lenght from valve to Horn limit, looking for second harmonic at your rpm wanted, that's all,
  8. Hi, here my 260 2+2 just finished : rebored block F54 (90 mm) P90 head with cam, injection ITB's ( gsxr) mégasquirt/Edis 6 Dry sump pump, electric water pump davis craig, custom idler gear, OBX lsd, etc , etc , Big brakes front/rear all body parts in fiber glass/Polyester : front and rear hood, fenders, doors, front and rear , etc etc i made moulds myself . Gotti wheels 225/50/15 front ,,, 245/45/16 rear Plastidip with custom color, pearlizer finishing coat
  9. Well, i'm working on my Z sometimes, not so much anyway, i'll try to make photos of my pan, steering rack, etc ...as soon as possible
  10. I made my own oïl pan with a sheet of aluminium, with a Weaver bros dry sump pump system, and lowered the steering rack, and cross member,, so i am about 50 mm ( 2 ") lower . You have to realign the gear box bracket ( 25mm or 1") Of course, you have to modify the steering geometry to avoid any " bump steering" on such a bad suspension and steering system
  11. OK,Matt, I have read everything, and i have the solution : Go for injection .......
  12. Not sold , and not relisted ...what's the future of this head ? who knows ?
  13. I swapped the two antic fusible links with a modern fuse box Peugeot . 4 x 30 amps blade fuses in a little box. very smart and reliable some pics :
  14. Stil growing....DOWN ;;;; eh eh ! $9,950.00 http://www.ebay.com/itm/Datsun-L6-DOHC-Cylinder-Head-240Z-260Z-280Z-L24-L26-L28-Fairlady-Z-Nissan-/261378053354?vxp=mtr
