Hello everyone,

Some of you know my car. this Dec 20th would make completing a yar of me owning the Z. its been great, reliable. and takes abuse on a daily basis!

I recently purchased a VQ35DE stock short block, and I sent it to a reliable machine shop here in San Diego, it was torn apart and everything looks great.

So I plan on keeping my 530 turbos, and I will be talking to AAM for them to make me a custom downpipe and eliminate my test pipes. I know that the ones designed by JWT create boost creep really bad, and are so restrictive.

I would like my build to someone be apart of this community with your advice and help. of course I am on a budget here!

I am not shooting for anything crazy, I would like 550rwhp max. and I know its achivable even if i am in just the 500rwhp I would be happy.

so, I am going to get this extra block built while still beating on my stock one.

50/50 mix of 100 oct and 91 with a peak of 11-12psi daily.

So this is what I was considering for my engine:

Weisco pistons but JE comes to mind because it 9.2:1 (dont know if anyone used them)
Eagle rods (but my tuner tells me that they are heavier than stock) and go Pauter?
stock bearings
Cometic HG's
All ARP hardware needed
block assembled
decked
blueprinted
heads reserfaced and pressure tested
.20 over bored


I was thinking cams but I would rather spend that money on a Haltech.

what do you guys think?

I havent dyno'd my car in a while since my first dyno, it was with HFC's and HKS TD. not with TP's and Greddy with is .5 inches bigger than HKS I am assuming its greater than 380rwhp

 

nvm.

 

Good Luck!!

 

i think with what you got planned, and your list of mods you tend to go with on your next build you should be at 500whp easy.. def. ditch cams and go with the haltech

 

You may want to consider going with the HR stock headgaskets if you are keeping the studs stock as well - they are cheap too. Eagle rods are fine, the Pauter rods look nicer, but my understanding is that either set will do the job. One thought about the cams is that it is a way to get good power out of your build and it is much cheaper to have the work done with the motor outside of the car, but a good EMS is needed first.

Good Luck and take pics!!

 

thanks guys, i was thinking all ARP main and head studs, but HR's one are better?

 

this is def. up for debate. some guys have had luck with the hr head gaskets. Alot of guys swear by hks.

 

I would stick with HKS headgaskets. They are proven. I have heard of problems with other headgaskets, especially Cometic.

As far as rods go, most of the aftermarket rods for high hp applications are heavier than the stock rods. I beleive that the Pauter rods are even heavier than the Eagle rods (I think by around 50 grams or so per rod), which is why alot of people are now going with Eagles (also the Eagles are about on-half the cost of the Pauters). It is my understanding that if you are going to go north of 850 RWHP, then the Pauters are a good choice. If you will be under 850 RWHP, then Eagles a good choice because they are lighter and less expensive.

In my build I went with Eagle Rods and Wiseco Pistons. I spent the extra money and got the ceramic/moly coating on the Wisecos. The moly coating on the side skirts lowers friction, and the ceramic coating on the top of the piston distributes heat more evently, thus reducing the onset of pre-detonation. I have already laid down 584 RWHP, but we had to stop because the wheels were slipping and they were getting chewed up. We will be back on the dyno with different tires this week looking for more.

thanks for the advice, but weisco 8.8 or 11 and i need like 9 or above, to the same feel of my car now just safer

 

you will not notice a difference from 8.8 to 9:1. for that matter, you wouldn't notice a difference from 8.5:1 to 9.5:1.....

 

comments above..
I will be very important for you to do a good ems, haltech proefi, hks vpro are all very good options. Also at the very least IMO you will need 800cc injectors fuel return and pump to be in the 560ish so if you want to push it further check SP tripple pump hanger, or CJMS or APSs fuel setup.

 

Eagle rods actually I believe are the only lightweight aftermarket rod option.
I am doing a similar build but selling 530bb and going with 700s.

 

*****.....lol....why not go with 850bbs

 

I know don't tempt me!

I dont have the ***** to go big.

 

i was thinking about going witg the 700bb, but I would like to see what happens with the 530s.

if I keep my stock head, can the rev limited on the DE can be pushed to 7k no problem?

I may go with Tomei cams, but just not sure yet

 

as you guys know, the jwt has am FMU.

currently, I have kept that on the car, and I think its good.

I have 600 DW cc injectors now. with the pressure applied from the boost via the FMU 11PSI the injectors are at 36% duty cycle. via the SS box. peak fuel numbers are like 6.8 (volts, for those who know the R4 software)

I will be running the SS box for the break-in 3PSI boost for 1000 miles and then everything 200 i will add 3PSI till I reach 15 PSI. and all wil be controled with HALTECH!!!

 

how do you guys feel about VQ35HR head and main studs????

 

Agree, I have 8.5:1 and it still drives like stock. Tons of low end grunt still.

EMS and tuner determines if you'll have good driveability

 

I realize this thread is a little long, but there is a ton of good info in it. This is why I went the way I did with my build.

You can always PM Joe and ask him questions as well. There are some slight cooling benefits to the HR gaskets too, but there are other proven stud & gasket combinations.

 

thanks for the thread. yea it is long
