Port/polish guinea pigs, flowbenched, guaranteed increased CFM
Ok, I posted a while back about an Altima 3.5 I was working on. We gained a GOOD deal of hp with a few minor bolt ons and some bowl porting and a nice 3 angle valve job.
Here's my proposition:
If anyone would like to be a guinea pig, I will do a full street port and polish on our flowbench for a VERY cheap price. The increase in CFM will be documented, and I will pay for before and after dyno runs.
Procedure:
You dyno your vehicle, and list all your mods. (Paid by me) Minimal mods preferred, as I would like to have a good baseline to go from.
You or a mechanic remove your two cylinder heads from your motor.
Ship them to me.
I ship them back to you.
You or a mechanic replace the heads.
Dyno again, (paid by me).
I'm confident that on an otherwise stock motor, you will see gains of AT LEAST 10-20 whp, again, I say AT LEAST.
This modification is a MUST for anyone choosing the all motor route. The infamous "heads and cam" LS1 motors you see running the streets, including my current 9 second full interior LS1 built by my grandfather's shop (the guys doing the work), all have aggressive cams with flowbenched heads to boot.
My original intention was to obtain my own 350Z, and do my own independent testing and get a dyno sheet out to the public, but my plans have been halted by my new project car; '92 240SX coupe w/SR20DET motor.
Now, I turn to the public. If anyone is interested, PM me.
Flames, challenges, questions, comments, rudeness, all welcome.
Cheers,

Ill consider it. but the big question is, how long is the turn around time? and if we need a mechanic to remove the cylinder heads, do you cover that too?
oh and of course, you should offer some proof that you are who you say you are and we wont get stiffed or robbed or returned junk products.

I recently purchased a used VQ35DE. I may only be using the short block, I have to check the head gaskets between the VQ35 and VQ30 to see if all the fluid passages are close so I can use my VQ30 heads so my intake manifold will fit.
I might be interested in parting with the heads. They are from a 02' Maxima with 10k miles. All the part numbers are the same as a 350Z & Altima. I am perhaps two to three weeks from having the heads off the block.
Nice guy, if you could do some work on a set of VQ30DE heads for me perhaps we can work a deal if you want a core set?

Actually, I can do work on any type of head you have. I'd REALLY like to get hold of my own vehicle, but can't afford one right now.
I would have the heads in my possession for about a week, no more.
Also, if anyone is planning on high hp forced induction or nitrous applications, I can duplicate the stock rods and pistons and provide a complete internals "kit" for anyone looking for lots of power and reliability. All I would need is one stock piston, and one stock rod. Pistons and rods would be forged, and balanced.

Pretty intersting. Any chance this offer applys to a 2002 maxima? Or would you be willing to port out the heads on my 2002? What would the price be and total turn around time? Thanks!

PM me for pricing...I'll do it cheap.

I have been cosidering a forged, balanced set of internals, but I can only work with someone I have met.

Don't expect to meet anyone from Crower, JE, Manley, Eagle, or any other producer, either.
But I do respect your concern. I'm just trying to help out the community. I'm mainly a browser on this forum, and don't post much, but I'm tired of all the threads about intakes and exhaust and "my hyper ground system gave me 1 hp!". I'd like to see some high horsepower domestic killing 350's running around.
Ah, port this!
Did you ever post before and after graphs on the Altima motor?
(not a Z owner yet, just curious, since I've been wondering what could be done with a port/polish/3 angle valve grind.)

Nice Guy,
Tanks for the polite response and not taking my coment personally. I am dieing to pump some F-1 technology into my 350Z. I am just really concerned with wasting my time.
If you can e-mail me directly (wizeline@yahoo.com) I would like to contact you and chat about possibilities, and what type of financial imput / potental gains we are talking about.
I hate to sound like a jerk (please don't take it that way) but if you can also fill me in on some of your past experience and let em know who you are. I know there are alot of wanna be gear heads in here that talk about engines but have neve leveled a RB26DETT head with two straight edges and a ruler.
I would love to find an experienced machinist that can create F-1 quality work without the 1.5 Mil price tag. A bit much to ask for I know.
San Jose have tons of parts places but I haven't found the skilled hands to do the work yet.
Thanks in advance!!

Hey NiceGuy,
Have you had a chance to tool around with any of the other VQ engines? And what kind of difference between a 3-angle and 5-angle valve-job. Is it mostly just a better seat position for the valve and head?
Thanks
Drew

Port and polish and cc heads
Not sure exactly what is planned for heads but may not see increase in performance on Z you see in Camaro. My experience is that heads on American cars were not very clean castings etc., and therefore had much greater benefit from porting to clean out (sometimes major) imperfections. Heads on Z likely to be very clean, and assumed close on cc.
Does anyone have specs on balancing engine components, rods, pistons, etc. for the Z.

The heads on my Camaro were the best (stock) flowing heads ever made. The LS1 motor was equipped with cathedral-type intake ports that were so ahead of their time, nobody thought they would benefit.
Now, a simple LS1 motor can put 481 whp to the wheels with just exhaust, lid (intake), and a mild cam. Why do you think everyone with a LS1 motor goes "heads and cam"? Because they can easily put 550+ to the wheels with a simple cam and port work.
I'm making a very educated guess that the heads on the Z need a LOT of work.
