Can you daily drive a closed deck engine?
There are no downsides with daily driving a closed deck, no overheating issues whatsoever.
Is closed deck better?
Better cooling efficiency due to an open cooling channel between the block and the cylinder and having full contact between the coolant and the upper portion of the cylinder. Lower manufacturing costs since less material is used. Easier manufacturing since it has fewer details and takes less time in production.
How much HP does a EJ205 have?
Subaru EJ205 Engine Specs
|Valvetrain Layout||DOHC, 4 valves per cylinder|
Is EJ25 open deck?
Semi-Closed Deck These are found in most EJ20 and EJ25 Turbo vehicles. Semi-Closed deck blocks offer reasonable strength and an open coolant passage to the cylinder head for optimal cooling.
Is ej257 closed deck?
This closed deck block design has been proven to withstand extreme boost levels resulting in high cylinder pressures without the worry of cracking a sleeve.
Can you daily a closed deck block?
A: Yes, this block is suitable for a daily driver. The closed deck inserts have no affect on cooling.
Is the EJ207 closed deck?
EJ207 CNC Closed Deck Modification. Designed to strengthen an EJ207 block for high power reliability.
What does a closed deck do?
The closed deck engine case was designed to support high power and boost applications. Machined inserts are specially pressed into the deck to completely fill up the space around the cylinder, whilst retaining coolant ports to allow adequate flow and cooling.
Is it necessary to deck a block?
If the block is NOT square it’s a no brainer, gotta deck it. If it is square and it passes a flat test using a straight edge and a feeler gauge there is no “normal” reason to deck it at all. If you want to get fancy and go for zero deck height (not a bad thing) or some other “race ready” reason, then deck it.
Is the EJ205 a good engine?
The Version 5 and 6 EJ205 and EJ207 is a good motor, but it is over 15 years old now. It is considered reliable and will make around 250hp. Unfortunately, users have few tuning options on the stock ECU.
How much HP can a EJ20 handle?

What is the best EJ20 block for a closed deck engine?
Possum Bourne Motorsport have designed and developed a CNC program to close deck EJ20 blocks. PBMS recommend moving to a closed deck 2.0 if targeting in excess of 330kw/450hp at the wheels. Using an MY98 EJ207 will give the ability to have a closed deck block with a rear-thrust crankshaft.
What is a closed deck block and how does it work?
The solution is a Closed Deck Block, which provides support around the top of the bore. Unfortunately, the factory produced EJ20 Closed Deck Blocks are becoming very difficult to find in usable condition. Possum Bourne Motorsport have designed and developed a CNC program to close deck EJ20 blocks.
Can I have a closed deck block with a stroker crankshaft?
Using an MY98 EJ207 will give the ability to have a closed deck block with a rear-thrust crankshaft. These have a larger thrust bearing surface for better bearing life, and will accept a stroker crankshaft for larger displacement. We have the CNC program to close deck EJ20 blocks with the following casting numbers.
