So, in the quest for more and more power, and in my case a larger margin for error, lower temps, and a precautionary tear-down as a response to an unknown noise I am building another motor for the Z. This has been in the works for some time and I should be up and running by ZDAYZ this year. The biggest changes were the cams, ferrea valvetrain and the highest end Carillo Hardware. Otherwise ill be sticking to a fresh block and crank with .020 over pistons.

Block Specs:
Carillo Rods With Pro Bolts
CP Pistons
ACL Pro Bearings
ARP L19s
ARP Mains
Dynosty Billet Girdle
Dynosty HG
Rev-up Oil Pump

Head Specs:
Tomei 272 Cams
Ferrea Ti Springs & Retainers
Ferrea Ti Valves
OEM valve seals

Turbo Setup:
BP 6766 Twin Scroll
Momentum Manifolds
Cosworth Intake
Haltech Pro Platinum
Haltech Boost Control
Haltech Dual Wideband
Haltech E85 Flex Fuel
AEM Fuel Pressure to Haltech
AEM Oil Pressure to Haltech

Fuel System:
TBD

I will continue to update this post with more information as it becomes available. I will also post pictures of updates. Also the fuel system is the last area for change as I figure my new goals is fuel.

I would like to thank the guys at Dynosty and Sasha for patience and helping me decide between abandoning the Z and a new motor.

 

Dynosty Headgasket?

how much power you expecting?

Good Luck! Glad another person didn't switch to a Vette

 

Yes the Dynosty Headgasket is a pretty perfect option for those who want something better than the cometic without the cost of the cosworth.

It wouldn't have been a vette... I am not sure on what to expect for power. I guess it'll depend on fuel and tuning. The best answer would be MOAR!

 

I see you have one 6766, I raise to two

Looks like a good build man, look forward to the finished product. What clutch, if manual?

Cool, is there room for a slightly bigger turbo?


I am gonna guess the car you would've abandoned you Z for, a Porsche 997 turbo? There is one for sale at the Kings dealership.

 

There is not any more room for a larger snail, I have already massaged things to get it to fit. I was looking at 2011-2012 Maserati Granturismo S. I love a FR GT car. I had one for an extended test drive and if it hadn't been for me getting married I'd have purchased it.

 

NICE! I notice all those cars rolling around here!

 

Why Tomei over Kelford? (I'm going to guess long source time with Kelford) 1+ oversize valves? Seems similar to my engine - should have a nice torque curve!

 

Good to hear Don...looking forward to the results with this build. If there is anything you need with regards to the kit, just let me know.

I think with all the upgrades on your head, you may be close to 600whp on the DD at Dynosty on pump gas (from memory, I think you made 560whp there already with the old set-up). That would be awesome...I think Hal made just a bit over 600whp on his GT42 powered Z way back in the day.

Too bad that Precision doesn't offer the 7276 in a twin scroll configuration.

 

10:1 compression I hope! When I refresh, I am def going 10:1 or 10.5:1

and supertech > ferrera


Sasha, you just need to start building a kit around these http://store.forcedperformance.net/m...de=NTFPSUPER99

 

Dam I'm in on this..GL w it all and I was going to finally make it to zdayz this year but unfortunately cannot again..next year is set I'm stone...I know its a while away but I keep trying to go and things come along..I'd love to meet some of you guys and see the big power in person also.

 

That may just be straight bolt on to the twin scroll kit. Would have to have it in hand to make 100% sure thought. The T4 1.15 a/r would be the way to go..not a bad choice for $1,900.

 

RC are you running Kelford? If not what are you running? I'm running their 272's, but going with a custom setup.

OP, +1mm OSV is really a waste of money man for the power output you'll be making. Crap even with my twin 67mm I'm using stock size valves.

I made 602 at 17psi on DJ with the 272's and stock size valves. I don't see him having too much trouble getting close to those numbers. I had a GT3794R at the time. Be interesting to see what his graph looks like compared to mine when he does dyno.

That would definitely be ideal I hope for the build, especially since he will be running corn juice.

I have full supertech right now, used them in many builds without any problems. However, I think on this new head I'll most likely make the switch, all because the guy doing my head knows their product a lot better than I.

OP, I'm definitely staying tuned to the thread.

 

Yes

 

Stock sized valves, stock porting, and basic 3 angle.

I chose the Tomei over Kelford for only two reasons, price and lead time. The Tomei are 780 a set shipped and have a very good reputation and similar cam profile to the Kelfords. The Kelfords are also flawless but are more expensive and take 6-8 weeks which is time I do not have. I also wanted to try something different. If I can make just as much power on the Tomei and they are as high quality as the Kelfords it would really put a strain to drop the prices on Kelford.

Ferrea was chosen by Dynosty. They say they have very good results with that setup on stock sized valves. I trust their judgement on this.

The pistons I have now are 9:1 I am going to keep those and run new rings. I only have two corn stations within 30 min of me. I hope to be on pump most of the time so the lower comp is a big factor.

Also we are not sure until I get the results but it looks like one of eagle rods may have failed. It is showing discoloration and possible stress fractures. The engine oil apparently was clean though, so the bearings and rest of the motor was intact...

 

Yep kelford 272s (no driveability issues at all), ferrea +1mm valves. All the components were selected by Dynosty (Hal and Ed). Ferrea I believe is more expensive than supertech but I don't know enough about either to make a statement about quality.

 

Good luck with the build bud. Hope to see this beast at Zdayz this year.

Chris

 

That is the turbo used in the " The Little Hero Super99 2000hp+ GT-R ETS Turbo Kit"

 

All this for $2k....damn.

 

In for the new build. I believe I saw your Z on the strip last year at zdayz, no? Looking forward to seeing it on there this year. Good luck with everything
