    Hi there as the Thread head says im Looking for a place to buy new LIM Bolts and Superchager to LIM Bolts as i am building a L36 into a L67 with 8Psi Boost i have searched and searched called holden apprently they dont make them any more and said to use aftermarket bolts and the best i could find is getting the bolt specs and having them matched from a good Nuts and Bolts shop (if that would even work IDK). Be for this Thread is Hijacked i know that the stock internals can only handel a max of 10Psi for a short time so i lowered it to 8Psi to be cautious also running stock compression with stock injectors to reduce the ignition forces. I am Building this for a Burnout Car Looking to get Boost from the moment i put my foot into it for the initial power from the charger not for Drag runs.

    Titanium is for those who measure every gram on a race car, for any other purpose it's not worth the cost. Grade 10.9 or 12.8 (high tensile) would be more than sufficient, factory bolts are grade 8.8 I believe. I run the MACE spacer on our L67 and it come supplied with new cap screws which really is complete overkill when the blower bolts are only torqued to about 20 Nm and the LIM bolts are only 15Nm. highly recommend using a thread locker compound on both.

    i will be Immortality this car is being built to be a burnout car so i went titanium so i can torque them down just that tad more because the stock torque specs allow the charger to separate from the LIM Quickly so i Did my research and titanium bolts can torque down more in N-M than High Tensile eventually i will be poring more money into it to upgrade the internals and its always nice to see shiny stuff in the engine bay those bolts will help it shine :).

    So my Mate that was helping me build this engine can no longer help back at work now so im prity much kastuffeld so here is the problem when putting the lim to the block i dont know the sequence to tighten the bolts same for the supercharger to lim sequence also any one know where to get custom piping that wont cost a fortune as some reason where the top radiator hose goes to the thermostat its on the firewall end of the passenger side of the car(if this sounds funny please do tell as it seems to only align that way).

    There are very specific tightening steps/sequences for both the LIM and the Supercharger. I'll post the info later when I can track down the right pdf.

    Not only do you need the bolt sizes up the top of post (they are to mount supercharger to intake) you will also need these bolts 5/16 X18 @ 1.1/4 inch high tensile grade 8.8 or above. I was able to get my hands on 200 of them and am selling them in packets of 14 There is a Limited Stock of 14 packets left here's a link to them: https://www.gumtree.com.au/s-ad/mel...1-4-inch-bolts-packet-of-14-black-/1206999555

    The new sizes listed are needed to mount the Lower intake Manifold to the block (If i had known it was so hard to find these bolts i would never have brought a supercharger kit with some missing bolts)

    Never Mind the 5/16X18@1.1/4 is wrong found that out the hard way now a bolt is stuck in the head tried to easy out it but the easy out snapped inside the bolt now and the head is damaged around the snapped bolt hole so i do have the stock vt heads just wondering where i can find details to drill the injector holes as the heads are the same except for the injector ports need to be drilled out any help would be greatly appreciated as after buying s/c to lim bolts and lim to head bolts have added an extra $150 to the expenses that i did not have. when i brought the s/c kit as a whole with all top end bolts it was at a mechanics shop being stored for the owner i brought it off when i picked it up the bolts were missing and have since rang the mechanics and they said the bolts were not there, no wreckers that have these engines would ether sell/ give me just 1 to have the bolt made up and after looking and looking online for the specs the bottom lim to block bolts were wrong , i dare not try the first bolts that i brought s/c to lim bolts as i too scared to find out they are wrong too.

    ok after finding out the hard way it is the size i got but i got unf these bolts are meant to be unc, so basicly i put a fine thread into a corse thread now i have the intake on and torqued down now since changing the bolts from unf to unc and having the thread doctor save my heads. Now any one know where all the small rubber seals go for the mace regrind kit i do know the 2 orange seals are the supercharger o-rings then there are 12 or so black seals i think they go into the rocket covers but that leaves me with 12 brown seals with 2 metal rings on each one would not have a clue where they go any help? Greatly Appreciated

    also little brown ones with the 2 metal rings on each one dose not fit into the inlet manifold to head bolt holes little to big but it dose fit in some of the holes for the supercharger on the inlet manifold.
