Tomei Launch Even Bigger Upgraded Procams for the Nissan GT-R

November 13th, 2010

Since launching their first upgrade Poncam camshafts for the VR38 back in March, Tomei has been busily preparing some significantly more hard core camshafts for the more heavy breathing VR38’s around. Recently they announced the availability of these Procams which look to be the biggest set of cams that the VR38 has seen to date.

Adding to the existing 256 degree 10.25 mm IN and 264 degree EX 10.50 mm lift Poncams which come as a fixed set of 4, the Procam range gives tuners the ability to select from a long list of profiles to mix and match on the Intake/Exhaust side. Here’s the full list of cam profiles available:

Once you’ve decided your application and selected your cam profile, price is fixed at just $550 MSRP per side so you’re looking at just $1100 all up for a full set irrespective of the profile you choose.

Hit up the Tomei website for more information or contact your favorite distributor of Tomei parts to order your set.

Tomei Poncam Camshafts for Nissan GT-R Now Available

March 24th, 2010

Prior to Tokyo AutoSalon 2010 we had seen that Tomei were on the brink of releasing these camshafts for the Nissan GT-R’s VR38. We’re happy to announce that Tomei has released them and they’re now available.

The Poncams are designed specifically as a drop in upgrade to run with the completely standard valve train. They’re said to give VVT enhancements across the entire rev range. Exciting stuff, the feature list reads as follows:

  • Made from special materials specifically for the VR38DETT
  • Precision grinds
  • Valve timing has been pre-set
  • Compatible with the stock valve springs
  • Best turbine response
  • Variable Valve Timing compatible
  • Stable idling
  • Best overall balance

As we suspected earlier on in the year, the Poncams are quite a big step up for a drop in upgrade. The specs are:

  • Intake; 256 Duration x 10.20mm Cam Lift
  • Exhaust; 264 Duration x 10.50mm Cam Lift

You can pickup your set at your local Tomei dealer listed over on their website. MSRP is set at the $1600 USD mark.

Tokyo AutoSalon 2010: JUN Camshafts TypeZero and Short Block with Liners

January 21st, 2010

Well the work-in-progress JUN 1000ps build with big cams is a great thing no doubt but not everyone is shooting for that level of ultimate power so they need a camshaft that will operate reliably with a more standard engine build. To fill that need, JUN Auto have produced this High Lift Camshaft TypeZero for the Nissan GT-R’s VR38DETT suitable for use with the standard ECU.

These camshafts feature identical duration and lift on both intake and exhaust sides which is 256 degrees duration and 10.3mm of lift. Not the 264 degrees and 10.5mm lift we heard for their big power build.

The price for these is set at a interesting 84,000 yen in Japan and about the $1,200 USD mark over in the states.

Update: You can now pick up a set for lower than our estimate, just $1150, online @ GT-RR

On the short block front, JUN Auto were also showing off their VR38 bare blocks with liners fitted. This is the kind of thing useful when you’ve spent the cash on the JUN Auto 4.0l stroker kit.

No pricing on the short blocks with liners just yet.

JUN Auto Nissan GT-R Camshafts Specifications

January 10th, 2010

The quest for the 1000ps JUN GT-R engine continues with the development of camshaft upgrades for the VR38. To get there JUN have opted for the biggest cam profile so far with 264 degrees of duration on both the intake and exhaust sides. Lift is also the most aggressive yet with 10.5mm on both intake and exhaust.

Pricing is not available yet but perhaps we will be able to probe deeper at Tokyo AutoSalon later this week.
