Dyno testing/Mikuni PHH jet advice for E88+F54

[EricB]

Hi all,

Morning!

Just went through the pics of last weekend's meet down at Nissan HQ which I unfortunately was not able to attend - bummer... I was all signed up and had a place reserved for me and everything.... sucks....

I never realized how much work it would be to swap out my old (Warped?) stock oil pan for a cast Aluminum one - that's why I didn't make it... How tight is the fit between the bottom front part of the pan and the steering rack when it's all in place? It looks like it is going to be pretty close....

I wish I could have seen that LY cylinder head - oh well, maybe next year, right?....

Anyways, here's the reason for the post:

So I'm just about done with the break-in of my new '81 F54 in which I put new rings/bearings in and my new early E88 already fitted with the bigger N42 valves on IN&EX...

For the time being no aftermarket cam but that's bound to change... Currently using an L24 one, the one that came with the the E88.

Carbs are 3 new Mikuni 44 PHH & I haven't messed with them, they are as they came out of the box... Has anyone found that they work better with different size primary/secondary jets? (sh*t, I left my notes with my stock jet sizes at home, sorry)

I am almost figuring that I ought to drag myself up to San Jose for a visit with Rebello for some set-up/tuning advice... Or maybe try to find a Los Angeles dyno tuner conversant with Lseries and Mikuni carbs... Don't get me wrong, it runs well enough I just wonder if it could be further optimized...

How do you feel about where timing ought to be? 7deg like stock on L24 or more like 10~15?

Or should I not even worry about this until I get the cam...
