Jotech Gives us a Peek at a Darton Sleeved VR38 Block
Always good to get a look at the finished product, after first hearing about Darton having sleeves for the VR38DETT some time back now, here’s the first photos I’ve personally seen of them actually fitted up.
These photos are courtesy of Jotech Motorsports based in Texas who are now offering the sleeving service for $1,100 in labour plus $1,325 for the sleeves themselves provided you deliver them your OEM block. If you want them to provide a block it’s another $3,231 on top.

Forged Performance Announce the VR38 FP1 Short Block for Nissan GT-R
It keeps getting more interesting in the built VR38 world with another newly announced complete, built, short block hitting the market in a big way. This time hailing from much closer to home for many of you, Marietta GA, comes the Forged Performance VR38 FP1 short block for Nissan GT-R.
The Forged Performance FP1 Shortblock strengthens the GT-R engine for maximum reliable power! We start with a BRAND NEW VR38 block casting, and all new OEM parts. The OEM rods and pistons are replaced with Pauter forged rods, and our own spec Arias Extreme Duty pistons. The block is precision CNC machined to accept a new cast iron cylinder liner. The cast iron liner allows for the long term reliability and exceptional strength when running forged pistons at very high power levels. The is the same proven strategy used in numerous 1500whp+ builds in the exotic car world. After the liners are fitted the cylinder walls are bored and honed to .0001 tolerance and the block is decked flat. The liners are purposely left .001 above the deck for headgasket seating and block expansion purposes. This block is engineered to handle 1000whp+ easily.

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