Monkeywrench Racing’s exclusive 2.0L stroker kit is the centerpiece of this engine. Increasing your displacement to a full 2.0 liters has many advantages; stronger torque throughout the rev range, quicker turbo spool, potentially lower VVL engagement, better throttle response. The 2.0L version also improves on even the 1.9L version with a stronger custom crank and stronger rod bearings. The V8 boys say there’s no replacement for displacement and after driving a stroked 2ZZ you might just agree with them.
All MWR built 2ZZ 2.0L stroker engines include:
– MWR forged steel 2.0L crankshaft
– Powder coated front cover and valve cover
– Brand new OEM gaskets and seals throughout
– Brand new oil pump
– ARP main and head studs
– Wiseco forged pistons
– MWR main and rod bearings
– Competition 3-angle valve job
– Your choice of upgraded valves, springs, retainers
– Expert machine work and assembly
We can build your race engine with stock or aftermarket cams- for aftermarket cams just select that option then check out the camshaft section of our store and purchase the cams of your choice.
2. Compression Ratio
Choose 9.0:1 compression for high boost turbo, supercharged or extreme nitrous applications. You can use the 10.5:1 or even 11.5:1 for low boost and light nitrous applications. Choose 12.3, or 13.1 depending on available fuel octane and tuning for the ultimate in naturally aspirated performance.
3. Connecting rods
Select stock or upgraded connecting rods for naturally aspirated and lightly boosted engine combinations. For serious turbocharged, supercharged or nitrous applications we recommend upgrading to MWR or Crower billet connecting rods for additional safety and strength. For maximum weight savings and high rpm performance choose Crower Maxilight (up to 500hp) or Crower Titanium rods.
4. Core Charge
Like most engine builders we sell these engines, heads and blocks on an exchange basis. That means that we require you to send us a rebuildable “core” similar to the engine, head or block that we are sending to you. If we’re going to send the rebuilt unit to you first then we charge you a core charge, which is a deposit that we hold on to until your core is returned to us and is then refunded to you. For a full refund of your core charge the core must be returned within 30 days and must be rebuildable- this means no holes or cracks in the block, no significant damage to cylinder heads, and no missing bits such as cam caps. We don’t care about pistons or rods. Valves may be bent, crankshafts may be scuffed.
5. Oil Pan
For cooler oil temps and better oil pickup upgrade to a Moroso oil pan. If you’re doing any road course racing this is a must because of the stock oil pan’s poor pickup which can cost you bigtime when it starves your rod bearings of oil. Also works great with turbo systems.
6. Port work
Select the ported head option to have MWR fully port your cylinder head. We smooth and reshape the ports and seats for the ultimate in flow. You can expect improved power throughout the rev range whether you’re turbo or NA with no loss of street manners.
7. Valve springs
Select MWR valve springs to safely rev 500-600rpm higher than the stock rev limiter. Add Titanium retainers for the ultimate in valve float resistance. Choose Ferrea dual valve springs and retainers for racing applications up to 10,000 rpm (may cause faster valve seat wear, not recommended for street use).
MWR’s top quality stainless valves work great for most applications. Ferrea’s valves are polished to a mirror shine. The intake valves are stainless like the MWR valves but the Ferrea exhaust valves are made of inconel which has exceptional heat resistance and is preferred for extreme turbo or nitrous applications.
Note: additional shipping charge (beyond what the website will calculate at check out) for delivery to residence or business needing lift gate service.
