Hi guys,
My name is Matt and i joined because i recently purchased an 07 Versa from my mother (lol). A short history on the car. Mileage is 325 000KM as of now, i've done all the required maintenance on the car over it's entire life for my mum. Coolant flush and fill, spark plugs (stupid job, and proper plugs are hard to find), transmission gear oil changes (twice now, first using Motomaster Synthetic 75W90, second using Royal Purple 75W90), all 4 wheel bearings, brakes, all the typical maintenance items. For a while i had told her it would need a valve adjustment, but now that i have it and the motor is nearing the end of it's useful life, i would like to do an MR20DE swap, and not spend any money on the existing MR18DE.
For documentation/posterity purposes i'd like to say the MR18DE in this Canadian market car has not had any of the piston slap that many other MR and HR engines have had, absolutely NO oil consumption whatsoever. In fact by the end of the 5000KM oil change interval i go by, the oil is still a healthy golden amber color, and feels fine between my fingers. Since it's an 07 the upper strut bearing recall fix has been done, many Versa's had the problem of upper strut bearings seizing up. The recall for a bad FPR to my knowledge has never been done, but has not shown any symptoms of going bad to this day. I've done fuel pressure tests on it a couple times in it's life to verify.
My mum has been very lucky with this car.
But now it's mine. I've always liked the look of the Versa, always been attracted to the "odd" looking cars as an enthusiast. I also have a 1987 Porsche 928 S4 as my project car. I wouldn't mind throwing a bit of money into this car and have started to already. I have a set of straightened 5 spoke Spec V rims powdercoated in light grey/charcoal metallic ready to go on the car, just need tires. I will soon be able to do a proper battery relocate, putting it in the spare tire well. This is convenient as the spare tire well already has a grommet or two to run the wiring on the underside of the car over the axle and over the heatshield through a small indentation on the drivers side of the car. After the battery has been relocated, this will free up the necessary space to run a homemade CAI i am working on. I am using 3" ID and 3.5" OD black ABS pipe. Direct 45 elbow/reducer will go on the throttle body, then piping will run to the headlight/fender area, and another 45 elbow will locate the pipe/filter to terminate at the drivers fog light. I am planning to use an AMSOIL EA 3590 filter, it is the biggest filter they offer which should have sufficient surface area to offer some gains over the stock filter. All lengths of pipe will be chamfered/rounded on the inside edges to reduce pressure loss as much as possible. The pipe will then be wrapped in a reflective material to prevent radiant engine bay heat from penetrating the pipe. The remaining PCV fresh air inlet on cam cover will then be protected by a small K&N breather filter.
The MAF will probably need to be recalibrated as it is factory calibrated to a much smaller cross sectional intake pipe, and installing the MAF into a 3" ID pipe will make it less accurate.
Eventually i'd like to swap a fully built MR20DE into the car, using one of the HP kits that importperformanceparts.com sells, i would be using their 11:1 pistons. Has anyone built an MR20DE with this actual kit? My concerns are with using the piston to raise compression, and valve clearance? Do the 11:1 pistons in that kit have valve reliefs machined in them so they don't hit them? I would hope so.
TL;DR i know, but i don't care.
