Jerminator: did you happen to discuss the why's and wherefore's regarding cams with Mr. Aardema? It would seem that you could put any type of cam in there from hydraulic flat tappet to solid and they would all still "behave" like a solid lifter setup. Is setting valve lash still a requirement?

Also, did Mr. Aardema happen to mention if there were any limitations/warnings on how aggressive a cam you could run?

 

I think you're right, they probably would all feel like a solid lifter setup.

We didn't talk much about the SOHC setup once he convinced me to try the Nissan heads. To tell you the truth he was very disinterested in his old work, got bored I guess. My kind of guy though, always looking for something new.

I could tell you the limitations of the DOHC nissan heads, but you might want to call Mr. Aardema about the conversion kit limits.

Just got my set of Infiniti heads in the mail!!!

I'll see if I can't post some pics tonight.

They look great though, it's going to be interesting to see how they fit onto the block. The main problem being the water passages.

 

post em up man...I got to see this

 

I agree, got to see this.

 

hmm....subscribing...

my first thought was even if the bore centers are close...how 'bout the water passages?...interesting to say the least...

 

Water passages into the head are not a big problem. The head bolt holes having to be drilled into them is.

Still don't have any pics, trying to find a camera. I'm still using 35mm full-manual SLR's

 

I'd worry more about the bolt holes than anything, maybe a LS1 block would be better for this since the head fasteners might work better in that arrangement. You can get a OEM dry sump setup then and run the ignition off of the crank reluctor wheel so you don't need the cam at all.

The cooling setup is what worries me.

Either way it's too bad you are in NC cause id like to see this just for curiosity sake.

so its gonna look like this:

those are some MASSIVE heads. what are you going to put this engine in?

 

Correct, Mr. Aardema said he would send me some pictures of his setup to give me a better idea on how he made it work.

Not really sure what the motor will go in, something small for sure. I might try to build an aluminum tube monocoque around it. It'll be a while before I have to worry about that.


Bret,

Where are you at? I may need to talk to you when I change the cams out. I can't seem to find anyone who makes blanks for this motor so I'll probably have to do re-grinds

Jeremy

 

How do these things do on lubrication in the 7500 rpm range?

 

You got me, Bret had a good idea with using a dry sump LSx block. I guess to be safe if I do use a conventional wet sump I can get a 7 quart pan and a high volume pump. But Dry sump is probably the way to go.

Anyway, thats a good point, I'll keep it in mind.

Jeremy

 

Jeremy,

I'm in NY. I know someone can do regrinds for them though.

Bret

 

I know I can get regrinds. The question is to what specs will they be ground?

These are uncharted waters I'm sailing in now...

I'm up in Baltimore on occaision, maybe I'll have to ride on up to NY and check out the famous (infamous) Bauer Racing.

 

I'm going to DC next weekend to visit a buddy.
