  1. Star Road Fairlady 360hp L28 :O

    Nice car , i was having a chat with the bloke on facebook last week about the engine , 3.2 L 330HP ,he said he has never said it was 360 hp , and he is only guessing , its never been on a engine dyno ,like most jap engines they run them up and they have a guess, about engine PS . We sent one over it was 350hp hear at the engine they said it was 400 at the wheels , i dont know how that works . best you dont beleve all that is said , and in car books
  2. AWS 86mm crank 3.2L Kit

    We do the same sort off kit with a longer stroke 89mm or 90mm billet 3.4 kit , the road kit is 89mm and cost $6000 US dollers the race 90mm kit will set you back about 9000 with all the gear
  3. Biggest bore L24 Block??

    We only make the hi deck on the 3.6 . 3.45 does not need it the 89 and 90 stroke use a 138 mm rod so comp hight is around 25mm on the piston so we can get the ring pack in no problem . The 3.3 89 mm kit is rated at 8000 max .because its only a budget kit .the 90mm kit will spin to 9 000 you just need a head and 50mm trip carb set to get it there .
  4. Biggest bore L24 Block??

    We have a 89mm rb stroke crank for the L 28 , We also have a 90mm , and 96mm stroke billet kit for the L28 block , i have fitted the 89, kit in the L 24 block with 86mm bore , made great power and torque , no need to go vo7 ,just to hard ,when the stock block works fine ,we have ways of making the deck taller. The 89mm kit comes with ever part for the bottom end , rods and pistons, bearings and custom flywheel , and ready to bolt in crank , cost $6500 + shiping also i check all sizes before its go out to make shore its a easy build
  5. Rocker arm wipe pattern

    i would try move the wipe , fit a 140 see if it moves it closer to the pivot end of the rocker
  6. Small port heads.

    It's more about port volume than velocity . When the valve is that small the air slows down as it can not get past the valve . And torque drops real fast as rpm is lifted . A large valve and the right port size for the engine will make more from 2000 all the way to 6500
  7. Small port heads.

    The things we think we know .. after years of porting , thinking all the air was in the top off the port ... Then we got 3d port air speed chekers and find all the air is not any place near the top , then we find we need to shroud the valve after the short tern in the chamber ,mmm the things we think we know lol . I think you all will be shocked what our new race port looks like with the port floor being flat and wide and lower than ever seen and the valve in a new spot.in the chamber . Lots to learn out there new tools helping old motors go fast
  8. Building a P90 head for supercharger service

    I think your spot on with your thoughts Xnke boost will drop , and the engine will make more power with the port job and port size , it has every time i have done this , ... one thing most forget with supercharged engines is the exhaust , make shore its at least 3in and free flowing , keep up the good work
  9. Building a P90 head for supercharger service

    BTW Xnke the ports are looking good , you could take more from the cheeks off the short turn , this will help in the top end from 300 to 500 lift , and wont hurt the bottom to much , keep up the good work should be a top engine
  10. Building a P90 head for supercharger service

    If you port to engine size and rpm you need to make the hp , a L 28 with a 88.5 mm bore that makes max power at 7500 it needs a 39mm port with 225cfm @500 will make 310hp with all the right gear on it , On my 3.3 + motors we did a test with port size , from stock all the way to a welded 41mm port , flow did not change much and it was all about x section and port volume , what we found was the engine just keeped making power in the top and torque moved up with it . TORQUE was at its best at 5500 with a 40.5 mm port , cam was the same 310d 550 lift , 260 @ 50 . this was on a 3.35 engine same test on L28 with 89mm bore same spec engine same cam and carbs Torque was best with 39mm port and was at the same 5500 rpm , so you need to port to engine size , and yes it has to be the right size for what you are doing , if you want power at 3500 you need a cam and head that work there and you need a primery pipe lenth that work there as well , AS for big ports being slow thats crap,,, there is only bad ports , if you port it right the L head is more than up for it at any size it will go , mach your port to the engine you are building , ....
  11. Small port heads.

    All the cams you could want are hear in aus , and there is 4 full time Datsun engine shops you can deal with to make shore you get the right cam , in fact if you send me the head i will flow it and give you a cam, that will do want you want . and will set it up so you can just bolt it on .
  12. Turbo intake manifold fabbing

    I made this one about 7 years ago , and fitted the injectors in so they would fit lol and it idled like a stock engine , engine made 400kw and drove nice , and was easy to tune , some times you just need to build them and see how it works , all the theory people said it wont work and it wont be good and will not idle , bla bla bla , give it a go and see how it goes .
  13. 81 NA Dizzy 180 degrees off

    HAHA i had that happen only 2 days ago on the dyno , your lucky when they just stop , hard to pick if they just move slow a few deg at a time , lol pin your shafts boys ,
