Forged Performance: Insane 350z Roadster Build...quest for the FI's Top 5
In past posts, go-fast has recommended eliminating the squirters and using coated pistons to preclude windage losses. I'm not an engine builder so just throwing it out there as something I would research if I were doing this again. You might want to PM str8dum1 as FP just built this same motor for his car. He's a research maniac so he'll likely be able to give you another perspective in addition to Sharif's expertise of course.
i wouldnt worry about the main caps. the standard Injected billet girdle is fine.
I would also, skip on the CJ hard line. Buy the twin pump and rail and have forged make all your lines. I'd use -10AN for the feed as well. That way it can be custom routed to fit your car exactly.
also better bet is to have forged get the DSS pro axles like alot of us use. That way you are not using any of the stock CVs.

If you don't plan on installing a traction control...impedance won't be an issue.....
The TC systems that have been researched on here will not accept less than 6 ohms. The ID injectors are the only one that will work for me.
Speak to Sharif ... He is aware of this issue.

My advise is to go with the ID now just in case....

Very nice build.....

We had not talked about installing a traction control system like you did, but it's probably not a bad idea.
Oh....how could you NEVER have turned the boost up? Weak knees?

To address a few of the other questions in this thread:
We are going with the Injected Performance Billet Main Girdle.
We chose the C8 cams over the C9 because one of the goals was to keep this build as streetable as possible. The C9's have a much more aggressive lift which we believe will make idle a bit rougher than desired for daily driving conditions. We believe the C8's will be a better choice in this case as we are not shooting for any power records

I was thinking of the C9s for a couple reasons
-heads are already apart for work so clearancing would be easy
-using +1mm valves
-wont need to be high rpm screamer with stroke and turbo size
-reflash the idle for 1000-1100
for reasons that XKR mentioned, is also why I concur with just going with ID1000s over the HKS's.
Are you really going with a 98mm bore on an unsleeved motor? That 1mm more than any other unsleeved block I've seen. Never read any discussion on what the maximum unsleeved bore is though.
personally I wouldnt wanna have that much power on a vert without a roll bar at a minimum (at least just for chassis stiffening). Hopefully that is in the works as well.

FCON with all the extras....Love it !!
C9...WOW...Sharif wanted to install that on my ride....but after hearing the C8....I felt that the C8 was a little too much for a street car as far as idle, but I still went with it......C9 was way out of the question....IMO

i wanna go with C9's but my curve is already soo right shifted. I guess in the end, i shouldnt try to worry about my power under 5000 rpms and use bigger cams.
But whats the fun of building something, if you cant upgrade later

Another good point and the subject of ongoing discussions... Thanks!

However, Mark's car is not going to be pushing that type of boost or power, so the stress level is significantly lower than yours. If he had the same goals as yourself we would not be going with the 98mm. As a fun weekend and occasional strip car I am very comfortable with this setup
Hope this clears things up.
good deal! i've just never read about anyone using more than a 97mm bore on an unsleeved motor. this will be a great build to follow. It should inspire more stroker builds and other options for larger displacement than just crank stoke

what traction control are you gonna run? i am at a toss up of selling my current fcon for a pro-efi, but am second guessing it. can you run e85 on your fcon?? and mind if i ask, what power levels are you at now??

I do not have it tuned for E85.... But yes....the Fcon can run it. The MadScientist ran the Fcon and made I think 650whp + on E85.
To date I have made 1006 whp...
impressive! i may just keep my fcon and save some pennies over the pro efi. going to be a great upcoming season. everybodies power hungry, i love it
