Engine Service from JGY

Looking for more power than 350HP on your SR, 400HP from your RB, or 400HP from you VQ and want it to be reliable? JGY has been building SRs and RBs for years and is well known for the quality and the power they can hold. From Washington to New York to Florida to the Caribbean to Finland, the world knows that if the block and head are stamped with JGY its going to make power. Nissan makes some great motors; but, JGY strives to out do them when they build it.


We have built motors available and ready to ship.

All SR motors including but not limited to SR16VE, SR20DET (gti-r), SR20DET (s15), and SR20DE roller rocker get built by JGY. All RB motors including but not limited to RB20DE, RB25DET, RB26DETT, and RB30 motors get built by JGY. Currently, JGY is ONLY building VQ35DE and HR motors. The 3.7 motor and cores are NOT available yet for work by JGY (8-3-11) which is subject to change later.

When the 350z and G35 first appeared, JGY knew it would be just a matter of time before calls would be coming in about building those motors. JGY bought a few donor VQ motors and started to work. Their first build was a 4.3L bored and stroked VG35DE motor...to say the least, they mastered that motor as well.



RB28DETT and SR24DET have both been built here... and JGY was one of the first in the industry to do both.

Over-attention to detail is used in all assemblies and measuring. JGY will completely tear down your motor, bore it, (sleeve it if desired) do a complete head service including cutting valve surfaces,, replace seals/guides, install pistons/sleeves/rods, measure/order/install all bearings, install aftermarket parts/cams/intakes/turbo, and then ship the completed motor to you ready to drop into your vehicle if you are not picking it up. They can even set up the shipping TO JGY from you. Each motor get stripped/washed/ and looks like a new motor upon receipt. All motor builds receive a free IN-house powder coat job on the valve cover/covers.
