Not to be a Dick but this has been beaten to death. Just do a search and every thing you are looking for is there.

Really depends on what fuel you will be running it on. 8.5-9:1 if you're running in on mainly pump gas, 10:1 if it's gonna be race gas or E85.

I would recommend the size pistons that fit in the bore. But that's just me.

I went with 9.5-1 on my stroker. Off-boost driving is wonderful. Throttle response for days and damn near insta-boost. But will limit boost if i dont run the meth. The engine is almost broke in and the tune isnt spot-on yet. A work in progress still.

Shearer Fabrications makes a manifold that would probably work for you (top mount twin scroll T4) don't assume it will be cheap.

Honestly, you might want to put that GT40 to the side for a while until you get all the other stuff sorted out. Realistically, once you're at that size turbo, questions about which manifold, piston, etc should either have obvious answers, or the question should be a lot more pointed and detailed.

well I understand the gt40 being it's size and what power it is capable of I understand what I would like to do.....I have been building my 7g galant for a long time and I am not in a big rush to finish it so all my parts that I was going to put on my 7g is going on my 6g....So long story short I have been doing this for a while and I will do it right one time only. I really want to keep all my options open that is why I always ask question and I am always researching parts so I guess in the end I really know what I want I just think there is always better ways of doing things...but thank you for the sugguestion.

I ran eagles with no problems.

You don't *need huge, gangster, aluminum rods to make big power, chromoly is tough as hell.

The powerband on this turbo on a 2.0 is about 5k-9k.

Make sure that all of your components will spin that high. (Engine, trans, fuel system, wastegates,etc)

You have a lot of work ahead of you, if you don't want to be ultimately dissapointed by your new turbo purchase.

GT40>E316G , but if its not setup correctly the 16g's will walk by you.

I hope your in for the long haul...

Well 638 and I will both tell you that DS-Map is about $500 or so better than DSMlink, seeing as it works just as well and is free software. Personally, I will always take speed density over a maf sensor.

Neither is a stand-alone system, they are both just remapped stock ecu. Just about everyone that talks about a standalone ECU is referring to a haltec, motec, or AEM system. Generally a universal ECU that can be put on anything and needs to be tuned from scratch and has every variable adjustable.

isn't that once they have the update for it?

It does have native GM Maf support though.

It's pretty much done. My V3 is on the way and we're switching it to speed density when it gets here. There are several cars currently running v3 in speed density mode with great success. Some big power guys are beta testing it and providing feedback which is what we're doing as well (if you consider 400-500whp big power). It just hasn't been officially released as an update. Read up on the link forum for more information or call me next week and I'll let you know how it went on the dyno.

Once I get a MAP wired up, I'll be running speed density with my V3. Money's tight right now though.
If you want stand alone and are cheap..... don't laugh...
check out megasquirt. It's not fancy, but it works.

Also you'll be just fine with 9.0:1 It's a GT40, it's going to lag.

by the way keep me posted on this. I'm really curious. I have high hopes for link. I don't mess with the sliders, just the factory maps.
