Going built engine

[Montegobluee92]

Its about time to keep dumping money into my E92. I know it makes more sense to just get a b58 or S55 but I love the body style and handling of my E92. Ive already had the car 5 years and will continue ownership. Its current setup is PTE6466 running 28 to 30 psi, port injection(750cc injectors), dual walbro 450s, 3.5" exhaust, and all the supporting mods. I'm looking to take it a step further and put in forged rods and pistons. I'm also looking to close the deck on the block (Epoxy or insert), swap in a ford 8.8, 8HP swap, and run an N53 head with cams/valve springs. The turbo is going up in size and id like to make sure it stays together. Im looking to build the block to handle 1000hp but not make 1000hp. The goal is 850-900 on E85. The car is being set up for roll racing events/ 1/2 mile racing.

My question(s) are,

Any recommendations on pistons and rods?

Anybody have experience here with closing the deck with epoxy or would the insert be better suited?

Anybody here running the N53 head? I've found fairly limited information there other than hydra performance posts.

Not sure but I think @ShocknAwe messed with N53 head. Could be mistaken was a while back.

If you’ve got an 8-bolt you might be okay with the epoxy closed deck, but you may be better off going with the insert and sleeves if you want to do things properly (regardless of 8-bolt or 6-bolt). I know this is an N55, but the block is very similar to the 6-bolt N54 block.

I wonder what the elastic modulus of that epoxy is? Unless it is close to that of the sleeves and surrounding block material, seems like it would be more placebo than functional. I also wonder how it impacts heat transfer through the top of the cylinder walls where the epoxy is? I haven't looked into epoxy closed deck, but seems like it could be bad idea, depending on the physical properties of the epoxy?

If you haven't already check out Darke Peak on youtube has Australia’s Fastest RWD BMW
tons of testing and info on the epoxy closed deck N54

Thanks I'll have to check out some of those videos when I get a chance

This is correct. N53 ported head and cams. It works.

Awesome, im glad to hear it works. What sort of modification is necessary to get the head to bolt on and everything else to function properly?

That was an interesting watch. It wouldn't make a ton of sense to spend the money on quality forged parts and then try to save a few hundred on epoxy vs the insert.

Drilled decked port matched. Then you need custom turbo folds to match the new head exhaust ports. Bought it complete from Hydra Performance.

Sounds easy enough. I had found a little more info on the swap through various forums. I priced out sourcing the head, sending it to a machine shop, getting cams, etc. It makes a lot more sense just to buy it done already. Way less of a headache that way too.

This should be your engine build breakdown

Mahle Powerpak Performance Pistons (Don"t go with anything else its all junk, these are cheap and fantastic)
Boostline rods (These things are absolutely beasts)
HCR Headstuds (4 corners drilled out 11mm)
Cometic Headgasket or OEM
ACL Rod Bearings + ACL Main Bearings
Stock head is fine or you can go the extra mile and do upgraded valve springs (Port the Intake and Exhaust side for more flow, a lot of people forget the exhaust side is just as important.
Go with an epoxy closed deck, CSS is pointless.
GO FULL DI DELETE DO NOT FUCK AROUND, Maxxecu or Emtron Standalone

Care to elaborate?
