Boosted G35 Sedan

Ahhh, nothing like a fast sedan so you can take more than one passenger but you take your family in while smoking the sports car next to you!  Ben’s G35 Sedan is a perfect example of this.  If it wasn’t for the Stoptech brakes this thing would be ultra sleeper.  Ben’s running a built low compression engine coupled with a JWT Sport 700 Kit (GT2860RS’).  Other mods include Cosworth cams and Cosworth Intake Manifold.  We suggested a few changes to Ben to make more BOOST more EFFICIENTLY.  We tuned it to run 9 psi and look forward to turning up the boost to 12-14 psi for more 4-door fury.

Here are the results after tuning this beast.  All on only 9 psi of BOOST.  We’ll be back after making some changes to Ben’s G!  14 psi here we come!

Dailey Engineering Dry Sump for the VG30DE(TT)

Over the last + year Bill Dailey has been working on a dry sump kit in conjunction with Mike from NZ and with some help from SZ.  For this we are proud to be distributors for this high quality, hold nothing back kit.  A must for serious racers that want to keep their engines alive in the rigors of racing.  Do yourself a favor and upgrade the heart of the oiling system!  The VG30DE(TT) suffers from poor oiling under stress due to engine design.  This stems from various things.  Poor oil capacity, hydraulic lifters, VTC system, the latter two suck up oil capacity like crazy and oil has a hard time draining back to the sump (pan).  This is why early on Nissan campaigned wet sump road race Z32s with drain back pumps on each side of the head.  A solid cam and lifter setup like the one JWT now offers is a good step in cutting down blood oil sucking parasites we know as the hydraulic lifters.

The dry sump kit includes the billet pan with integrated pump bracket, oil pump & spacer with optional oil & air separator, ATI damper and pump pulley tensioner assembly.  What’s not included and will be up to the user\installer is the lines and oil tank.  This will depend greatly on the vehicle setup.  Pricing not set yet and look for it starting this week.  It will be available for order on our site.  Any questions on the system can be directed to SZ.

You can see the integrated pump bracket.  Note the groove on the flange for superior sealing to the block.  Reuses the factory front and rear oil pan seals and silicone.

Pump mounted.  The pump will sit in place of the existing factory A\C compressor.  So yes, you will have to delete your A\C to use this system.  The turbo drains have their own scavenging section directly on the pump.

Complete kit shown.  Lines & Oil Tank not included.

Slacking and more Juice

I am way behind on my blog posts.  I’ve got more than 6+ months worth of posts and information.  Gonna try to catch up!  I apologize to the faithful readers.

Our bud Alex with his juiced Z33 came back for more tuning and testing.  We upped and played with the jetting with great success.  The initiation of nitrous was moved up to 4k RPM to keep the rods happier.

We gained another 20-30 more hp and torque.

Z32 Inlet Pipe Change

A few weeks back Mr. John G. from AZ brought his red Z in for some inlet pipe (ASH) dyno comparison among a few other cooling mods.

OK, I want to make this clear!  Please ready carefully and pay attention.  I know the public school system has failed many of the young Z owners.  The RED run was John’s previous best BEFORE the inlet pipes.  This dyno\tune was performed earlier this year.  The inlet pipe dynos are both the BLUE and GREEN runs.  The reason I am showing two runs is that you will notice the top end power is lower on the GREEN run.  The GREEN run I performed with the VTC system ON throughout the ENTIRE RPM range.  I was doing testing for those curious.  The BLUE run was normal but it showed lower power down low and I did NOT want to misrepresent have people think the pipes lost low end power.  You can see that on the GREEN run the low end power is on the par with the OLD RED run.  Hopefully this did not confuse anyone.   Any-who, no changes were made to the tune or boost settings for the sake of keeping things consistent and repeatable.  Between 3800 and 5500 RPMs we saw nice gains which anyone who drives there Z in the street can appreciate.  At 4700 RPMs we gained a sweet 50 ft\lbs of torque!  Horsepower was in the 40-50 whp gain.  This is on 91 octane fuel and Sport 530 Turbos.  Any questions please shoot Greg or myself an e-mail.  Pipes are available through our site here.
