Record Crankshaft

This kit is for a stock rebuild and includes everything you need for a complete overhaul. All that is missing from this kit is a timing belt, oil and water pump.

It is a little bit on the expensive side but this is because there is a crankshaft included along with all gaskets, oil seals and bearings. The crankshaft has been reconditioned and hot washed, shot blasted and inspected for any wear or scoring.

This would be a good kit for someone with scoring or wear on their crankshaft however this would not be common unless a broken connecting rod damaged the crank.

Pros:

• Comes complete with crankshaft.

Cons:

• This kit is pretty expensive especially if a crankshaft is not needed.
• No oil pump or water pump included.
• No timing belt.

Evergreen Performance Components

This OEM rebuild kit is the best of both worlds. It comes with absolutely everything you need for a full rebuild, including a timing belt, T/B tensioner, water pump, and oil pump.

Evergreen Performance pistons are made from premium grade aluminum with gas nitrited steel piston rings which say 50% longer life span. This D16y7 performance rebuild kit is designed for both stock and mild tuning. This means it is capable of handling most bolt-on mods you can throw at it except a turbo.

This is an ideal rebuild kit for your daily cruiser. The kit comes well packaged and all the parts are brand name apart from the oil pump. NPR Pistons, GMB water pump/tensioners, and a Mitsuboshi timing belt which are all good quality well known brands.

In my opinion, this is the best all-rounder, and at a good price.

Westcoast Hard Parts

This is a complete OEM stock rebuild kit. Nothing fancy but it would still be a solid rebuild. I don’t always condone eBay parts but this an exception. The kit includes everything you need including pumps, belts, tensioner, seals, and bearings. And when I say stock rebuild I don’t mean you can’t do mild tuning of your own, it would be more than capable.

DNJ Engine Kits

DNJ Engine Kits come complete with Pistons & Rings, Bearings, and a full sealing set with upper and lower gaskets. This kit is made of cheapish Chinese parts but they are pretty good quality and will work just fine if you’re not planning on racing every day.

All the parts are backed with a 12 month / 12k warranty and DNJ has a good customer service rating which is always good to know just in case the worst was to happen.

How Do I know If My Engine Needs to Be Rebuilt?

• Knocking/Banging noise coming from the engine due to worn internal bearings.

How Much Does it Cost to Rebuild a D16y7 Engine?

A stock rebuild for a D series engine would typically cost anywhere from $1400 to $1800. The labor cost would be $1200 on average plus $200 minimum for a stock engine rebuild kit.

If you are planning on going turbo you can expect to pay $450 to $800 for a high spec performance rebuild kit alone without labor.

Then you also need to include labor costs if you are not planning on building it yourself. Labor would cost from $800 to $1200 depending on the mechanic. If the engine overheated you would need to get the head pressure tested and possibly machined along with the crank and block if the engine is really bad.
