So planned on the calendar for next saturday is for me to pick up a spare VQ35DE, with the help of a rental car company and a friend with straps and a tarp.
So why am I getting a spare longblock? Well, first, what IS a longblock?
- A longblock, generally speaking, is a complete motor. Simply, the block (cylinder block) and the heads, with a front timing cover, and maybe some accessories, depending on how lucky you are.
I don't need the accessories because I'll simply swap mine over to it.
The only important thing to me is the block and the heads.
So why am I getting a spare longblock?
Let me list off the reasons:
- Eagle H-beam connecting rods
- Arias 8.5:1 forged pistons
- Cosworth rod and main bearings
- ARP head studs
- ARP main studs
- JWT valvespring kit
- Some secret stuff.........
I'm getting a longblock so I can assemble a built motor while I daily drive the 350z. This way, I'll be in no rush to complete it, meaning I can make sure all machining is done properly, and all assembly is precise and clearances are measured and within tolerances.
This will make for a much more reliable engine when finished, and one that will be the most efficient at making horsepower and maintaining high horsepower levels without failing.
One thing to keep in mind when building a motor is to have the rotating drivetrain precision balanced.
Why is this important?
When you purchased your car, your motor was specifically made to run with the pistons, connecting rods, crankshaft, flywheel, and crankshaft pulley that came in the car. Since I'm replacing the connecting rods, pistons, flywheel, and most likely crankshaft pulley, I must take these parts to a machine shop to have it assembled properly, and so that they can balance the parts together as a whole to prevent any damaging vibrations that may occur.
Also, many aftermarket parts companies say their parts are balanced off the assembly line, but that does not mean they balance together with other parts or even with that part's specific brother or sister.
So, when this motor arrives, expect pictures as we mount it on the stand and start the tear down! We'll show you specific parts inside the motor where improvements can be made via upgrading parts or simple cleaning or porting/polishing.
