Someone remind me WHY I wanted to do this!
car now has stock 2.4L engine, t-5 transmision, r200 3.9:1 diff, and some suspension mods.
2.8L with 9.8:1 compresion is in the works.
Now I'm just enjoying the ride!
Here is a link to one of our local club members cardomain site. There are a few pictures of his fuel tank that he modified with a sump. He is also a member of Hybridz.

ZR8ED I guess I type to slow!
In the TIZCC at least half of the members are from Ottawa. We usually meet in Brockville, it is mid way between Kingston and Ottawa.
For Ottawa and Kingston there is the TIZCC.ca (Thousand Island Zed Car Club) that I am a member of.
There is also the Ontario Zed Car Club Ontariozcar.com (for the Toronto area)
For Montreal there is The Zed Owners of Montreal car club. ZOOM

Thanks for running the c/r number for me. I was unawear that the lengine calculator was not accurate.
The cam I have is a .460 lift 270 Int/280 Exh. duration. For now I was going to run S.U.'s with SM needles until I can aford megasquirt. The maximum octane available here at the pumps is 94, with the correct ignition timing I was HOPPING it would be ping free.
After reading through posts for 3-4 weeks (before I decided to use my n42 head) I knew there was a good chance I may have problems with pinging. On the other hand there are a few people on this site that have had good results using the n42 head.
I'll have to wait untill it warms up and some of the snow melts so I can swap engines and post the results.
I have calcutated the compression ratio several times now and according to the lengine calculator a stock n42 head with a standard nissan head gasket on a l28 with flat tops gives a 9.82:1 c/r.
My n42 head has 41cc chambers (stock is 44.6cc) and using the lengine calculator this gives me a c/r of 10.48:1. I have run the numbers on a couple different programs and I keep on getting the same result.
Is there something that I am missing? Can someone double check my numbers for me?
Thanks
Just got my n42 head back from the machine shop last week and thought I should post a couple pics. After I had finished porting it and unshrowding the valves I had the machine shop shave it .060, do a valve job and shave the intake/exhaust side to clean it up.
With the .060 shave and unshrowding the valves chambers are now 41cc. This should give me a compresion ratio of 10.5:1 using a standard nissan head gasket on my f54 block with flat top pistons. The quench is much better now too.
This is the first head I have ported so any comments/advise are apreciated.
