LCR Pistons 411
ok, so I don't mean to dig up old dirt but I'm finding myself reading back at 05 postings when I searched off something that caught my eye on nasioc.
I noticed on there that they had mentioned that the 2.2t pistons were pretty much drop in replaceable for the EG33 high compression pistons. I noticed that a lot of people tried it on here quite a few years back and that a lot of things were found in this process. I'm just curious as of late, what besides getting a full long block from LAN are my options for LCR pistons for a turbo build?? Seeing as that LAN no longer sells the after market parts individually. Are aftermarket WRX or other impreza pistons and rods compatible with the EG33?? I know that rallybob has been doing a lot of work with high compression lately and NA but I'm still looking at turboing down the line. Please those that already know please inform me so I don't end up reading almost 4 years of postings.... thanks in advance Johnybeas |

PM Old Tom about it.
He and a few others picked up where I left off in the hunt for forged pistons. Dustin

Re: LCR Pistons 411
you might get dizzy reading that thread and I don't think the final info ever made it in there. To summarize:
SVX pistons come way "out of the hole" and ej pistons don't so any piston other than SVX pistons or custom made pistons will pretty much negate your squish area. If you were to use legacy pistons the turbo pistons would give you too low of a compression ratio; the na pistons would get you in the ballpark but you would have an extremely large gap in the squish area(over 40 thousandths if i recall correctly). |

Re: LCR Pistons 411

Re: LCR Pistons 411
its less about the compression ratio, and more about how those pistons are filling he cylinder and combustion chambers in he heads. Considering that the SVX head is unique in its design, the 2.2l pistons will not yeild your desired results.

Yes too low even for a turbo setup.

Re: LCR Pistons 411
Questions answered so pretty much I'm looking at getting some custom forged pistons made, or finding someone like mikecg who had a pair of your (lan) pistons they no longer need/want.
Do the rods from any of other subaru motors fit? could I look at say the aftermarket rods for an sti? or is it a whole different ballpark with those as well? |

Re: LCR Pistons 411
If you message obi on these forums you might be able to get him to sell you his set of rods.

Re: LCR Pistons 411
Well you see, right now I can't afford the turbo and all the rest. So buying the engine components for a build that without a turbo will kill my power, just doesn't seem logical. Thus the reason for my research and figuring it all out while I save my money, because, well... lets just say I'm not loaded lol

Re: LCR Pistons 411
Was just letting you know I know of someone who is stalled in their project and might be talked out of them.
Sounds like maybe you should be taking the small turbos on a stock bottom end or na build route more seriously. A built engine and forced induction system isn't a wise investment for someone that doesn't have plenty of spare cash. Quote:
