For years now there has only been one available stroker option for the VG30 engine platform.  Offered by one of the best Nissan aftermarket companies in the world JUN Auto, they were the first to offer a 3.2L rotating assembly for the VG30 that allowed us to take a step into the larger displacement catagory.  The upsides were ultra premium materials used with exceptional quality in details from the billet crankshaft to the remarkable “I” beam rods they included with the rotating assembly.  The drawback was the price.  At a healthy $12-13K consumers were rarely if not ever financially ready to spend that type of capital for a working piece.  I’ve personally built an assembly for a client that has utilized this exact kit and I must say it truly is a great product.

But now times are different and the racing industry has made it more available the items and systems we’ve only dreamed of to be part of reality for a large group of enthusiasts.  I spent a lot of time looking over the JUN Auto rotating assembly and paid attention to not only what was good but what could be better to allow a revised and ultimately much better designed system for the consumer who wants a much better option with a better more affordable price point in mind.

EPR has finally compiled all the details a proper rotating assembly should have and has made it a true reality to offer a very affordable rotating assembly that is a huge step above whats existing today.  The EPR 3200RA system gives all VG platform enthusiasts the capability to expand the power potential above and beyond what was then and is allowing it to be in your hands NOW.

This new system is a 3.2L Stroker Rotating assembly that is manufactured right here in the US!  Thats right, cheaper costs, higher quality materials and a faster turn around time than before.  I’ve incorporated industry standard features to both the crankshaft, rods and pistons to give you the consumer the absolute best system your top dollar can buy.

My rotating assembly consists of a brand new billet crankshaft made of EN4340 steel that has been triple hardened (ion nitride processing) with a “straight shot” oiling system better known as the HSOS.  Rod journals have been increased in both diameter and width to give the crankshaft a significant increase in overall surface area for oil and bearing function.  All journals feature a better filet radius to aid in oil relief and include a leading edge tear drop for better oil supply to each bearing set.  Counterweights have been modified to decrease parasitic drag within the crankcase and allow for more power potential.  Each crankshaft comes directly to you having already been dynamically balanced as well.  The rods (consumers choice on design) feature a ridge beam (Pauter designed) connecting rod that not only is one of the lightest rods offered but is the most functional rod in cutting through windage plumes within the crankcase.  The ridge beam is one of the most well engineered designs and has an excellent history of withstanding some of the most abuse seen in the racing industry.  Rods come with standard ARP 2000 rod bolts and come already pin fitted for a complete connecting rod solution.  Customers can opt to utilize an H-beam selection at an additional cost if they do not wish to use the standard ridge beam connecting rod supplied with the kit.  The EPR 3200RA comes standard with custom EPR spec’d forged pistons which have lateral gas ports for increased ability to promote a better ring seal to the cylinder bore, dual oiling in the pin bores and come full coated (crowns & skirts) as well as being pin fitted to round out the assembly.  Main and rod bearings are supplied.  King bearings are the choice used due to their composition and overwhelming quality compared to other bearings offered on the market.  All bearings will be fully coated with a dry film lubricant.

As you can see this is a 100% full comprehensive system that gives you the consumer a fresh and new look at power production at an affordable price compared to the current offerings on the market.  There simply is no better system available and when paired with EPR billet main cap & girdle kit your VG engine will be the biggest, baddest VG engine to hit the track and dominate the competition.

Each rotating system includes:

EPR Billet Crankshaft
EPR Forged Rods w/ ARP 2000 Rod Bolts
EPR Forged Pistons w/ Detail Specs
King Main & Rod bearings (Fully coated)
Dynamically Balanced
Custom Piston Ring Kit
HD Wrist Pins
KrammLox Clips
Piston Coating

Each EPR 3200RA Kit is priced at a remarkable price of $6500

Please contact me regarding any questions you have pertaining to this system.  These are available now and take typically 14-16 weeks to produce due to the custom application it is.

Theres so much to list on this build that I honestly would be here for a very long time drotting down the list of custom one off parts.  However I can say what this engine has is what every SOHC VG owner would dream of from a custom billet stroker crankshaft to my newly designed VG33 pistons, Billet main caps and new solid adjustable roller rocker arms, & Garrett GTX Turbochargers with custom equal length tubular manifolds.  The list is extensive and this client is literally allowing me to write the new rule book for SOHC VG performance.   This will be the bar from now on.  Check back with me periodically to see how this system unfolds to produce remarkable feats in the Z31 community.

STAY TUNED!!!!!!

I was contracted last year to build a VERY robust high compression (10.5:1) turbo build for a client in Houston, TX.  He wanted to do the build the right way and use the industries latest systems with coating applications, manifold design, machining and build practices.  I’ve gone through this setup with a fine tooth comb to the likes of the clients request and the product of final setup is nothing short of beauty.  There is a little bit left to go for this build to be a completed setup but the light is very near and I can’t wait to hear my clients enthusiastic nature to run this engine like it was meant to be.  More things to come from this setup!

More to come……

WINFACTORY has teamed up with EPR to produce a fully CNC machined billet fuel rail for the Z32 community. The birth of these newly designed rails from billet to final production shows the commitment EPR has to its community and WINFACTORY to get the job done! Currently we have a few that are done as test pieces to ensure programming and material are best suited. This will be a true billet product and will be the best option for top feed fuel system for the VG30!

Rail kits include all mounting hardware and fuel rail unit.  All rails are processed through a very unique anodizing process that is 100% corrosion free since the process impregnates the material with ceramic.  I only use the best processes on all parts I produce so that all my clients obtain the latest technology for their builds.  This setup requires very minor clearance of the upper plenum and once fitted fits under the stock throttle cable cover.  Now owners have a complete kit that essentially drops in and can be hidden to keep your engine looking unmodified to now show off the upgrade you have!  This is the best solution to topfeed injector conversion for the VG30DE platform

Here is the world’s first production solid adjustable tensioner for the VG30DE engine.

Say goodbye to timing belt flutter, slippage, failing hydraulic setting fixture, headaches & worries with the old system. Now there’s a positive solution to eliminate the issues associated with the stock assembly.

Pricing is $275 for a full HD complete assembly with the new updated tensioner body included. The HD complete tensioner includes a newer swing arm that has a wider contact face for the pin set to rest on for a better and more even contact between both surfaces.

Innovative and secure here is your solution!!!

Currently my new timing belt tensioner is used in many countries spanding from the UK to Australia and more.  There are quite a few currently in the US utilizing my new tensioner and all are reporting back stating they like this new approach much better than the factory system.

Feedback and reviews from clients stating:

I ordered EP Racings HD Tensioner a little while back. Finally got round to fitting it today and found it incredibly easy to install and correctly tension the belt. Looks better than OE quality and gives significantly more adjustment that the factory option. Great bit of kit

Thank you so much for producing this product!  This is by far so much better of a setup then the OEM unit I had been relying on before.   Now that I have full control over the tension of my timing belt I can set my tension and know that its set properly and not have to worry a part component will fail after a period of time.
