Turbo M20 2.8L Stroker w/ 135mm rods

..
That is a lot of options...i dont even know what I do or dont need as piston options...

Then you can't build that engine.
The variant is that someone is building it for you and you just seek for an advice here.
Better ask the guy who is building the engine on the options.
And also the guy who is going to tune the motor.
Otherwise, all the answers shall be provided by the EngineBuildingBird in remote mode and you'll be very happy to be advised by one of the Guru's on this forum and show off to everyone.

you're not contributing anything at all here. I'm surprised you haven't been banned yet. Not for being a retard, but for being an asshole.

I don't give a FUCK if I am banned from this forum.
And you are wrong, I am contributing. A lot.
Digger and EngineBuildingBird will confirm.
I have instructed them so since they are my inferiors and therefore slaves.

This car will be full time E85, so what should I do?

Gapless top will be fine for you ( conventional also good I'd still get total seal brand rather the Std ones from Je) , topend can do an OEM 8.8:1 dome style for 885 head on a piston for a 84mm crank should net 9.5:1 CR give or take.

Sometimes I wonder if you guys are serious about what you post.
9.5:1 CR for a boosted engine? Most N/A strokers go with similar CR and aftermarket cams.
Unless M/Ethanol or special racing fuel is used there is no way that decent boost is inducted into this thing.
No one mentioned about boost limits on this "build", but it is apparent that it is a fantastic project for a discussion.

It's not high less than stock b25 euro engine

Well if you would have read early, you would see that I mentioned this car will be strictly rsn on Ethanol only, as it is available at the pump here. I would like to stick with 9:1, though I dont think 9:5:1 would cause any problems.

As for boost limits, I'd like to know that as well, the stock engines have already seen 30psi and the car was a rocket, so I'd like to run 30-35psi on a 6266 when I need it. I am debating Oringing the block OR sticking with OE gasket and ARPs, just in case we have a problem with detonating during tuning. MLS has been brought up, which is an option. Power goal is ~600whp

The piston guy what you want they can mod as required, 9.5 is just what you get with Oe dome as is with standard valve reliefs.

Euro engines are 9.4-9.7 preface and 8.8 facelift.
They use totally different engine management.
8.8 CR are commonly turboed in Europe but the preferred CR is around 8:1. on 100 octane fuel and 1.5-6 bar boost.

Well, that's a quite of boost.
You may want to rethink the CR or face detonation issues.
If I were you, I would use 8.5-9:1 CR maximum even with Ethanol.

9.5:1 is not sweat, specially when you are using e85. The stock m20b25 is 8.8:1 and we saw 500+ at only 19psi - and it is the same turbo as yours, but ball bearing and t4 turbine (believe you said t3 for yours)?

[ForcedFirebird]

I am actually starting to enjoy Prostate's posts. Some entertainment between all these numbers and letter.

[apostate]

I am enjoying all of yours. But there are special ones that I made a collection of.

there is a cutring option

psig is just a bragging number. A lot of people ignore pressure ratios. It takes very little effort to plumb a pressure reference port in your exhaust. If you have a 1.5:1 or more ext:int ratio, the system is inefficient, 2:1 it's defunct.
