Supercharging my grey FB

srevoice · Post by **srevoice** » Thu Apr 26, 2007 7:40 pm

Hello all, I am just starting to restore my FB holden. It used to be a Tasmanian police car and i will try to restore it to her former glory. I am installing a norman supercharger ( I have the book for it too ) and was wondering what sort of mods I will have to make to the bottom end. This is my first full restore of one of my old cars and will be learning everything from scratch. First thing learnt was I have to get a custom set of extractors as the manifold is getting in the way of the inlet. Look forward to any help.

Welcome Andrew,
A good friend of mine races an appendix J car (Group Na) and runs a grey in a FJ.
Iv'e got to say he pushes the old gird hard and Im surprised how quick it does go. He does have engine failures no surprise there

mainly breaking the crank. The grey has only 4 main bearings and is prone to severe crank flex. I have built a couple of motors for him but they require a lot of maintenance.
To make them last we machine the main caps flat and install steel supports across the bolts (this saves the caps from cracking).
We polish the conrods and install good rod bolts. We fill the block with some grout to hold the bottom together and use a very large and custom harmonic balancer (a must for the flexing crank).
We also use forged pistons that are extremely hard to find.
Now all this stuff is super heavy duty for the grey under extreme loads so if you intend to abuse it then thats what you have to do to make it last.

Regards Greg

Wow...Norman supercharger!

There is a bloke (FCCOOL) in Sydney who is restoring a FC wagon with a supercharger - not sure if its a norman or not. You can email/pm through here http://www.fbekholden.com/forum/profile ... file&u=813

or check out his thread on the FE FC board http://www.fefcholden.org.au/cgi-bin/ya ... 75;start=0

Thanks for all the help, yes I am from Tassie, I have about 6 old holdens and go to the FE FC site quite often. As fo ar as I know I am the only one at the moment installing a Norman, so the info is greatly appricated. I wnot be driving this car hard, just want to go crusing in something diffrent and to be a bit of a head turner with the noise it will hopefully make. I will start posting pics as soon as I figure out how to do it.

Gday Andrew
Norman superchargers were primarily designed to be fitted
to standard engines.
Although a mild cam, extractors, lightened flywheel, & full balance
would do wonders for it.

Good luck with it
Cheers Jeff

Andrew, welcome to the forum , if you need to know ANYTHING about making grey motors go fast, send a PM to 4hammers on this site .
He is the grey motor guru and he lives in Tassie.

Rob J (4hammers) probably owned the norman at some stage!!! Leon (FCCOOL) has built a real hot red, but im not sure what type of supercharger he has but Im pretty sure its not a norman. A Norman in an FB what a package!!!! Good luck, keep yr eye out for a repco head to go with it. Id love to find a norman to put on the ol FC

Hi, yes 4hammers did own the norman a while ago, I brought it off him when he wanted another car. He now wishes he never sold it. I have sent 4hammers a pm on the FE FC site but I am still waiting for him to reply, too busy restoring his kombis.
