Default 97 lgt opinions on turbo?

soo..iv got my exhaust set up except for the cats ( still stock ).but it sounds beast! My car has some pull and picks up fairly nice.im wanting to turbo it now lol.Iv read that the open deck sucks for turbo and most would suggest a swap.but I also read that Changing the blocks and pistons could make this possible? Have any of you tryed this hybrid experiment?? . I feel like a swap would take all the fun out of it.Iv never gone further then exhaust and rims lol so ideas, opinions, experiences all excepted!!

The best thing to do is to bolt your heads onto an EJ22T and then bolt on WRX hardware (turbo, headers, intercooler, etc) for a super reliable turbo build but bolting your heads on an EJ22E will also yield a reliable turbo ready engine as well (I have built this engine & I am currently running it in N/A format).

Lets clear up a few things.

Open deck is very underrated.
The pistons to any open deck block will give out long before the block itself does if you're not running extremely high levels of boost.
Open deck is actually better for cooling purposes & should not be overlooked.
The EJ25D is not good for turbocharging as the rods are simply not up to the task & the pistons yield too high of a compression ratio.

If you turbo your LGT as is, you will need standalone engine management past a certain boost level, even before that point, you will need a piggyback ECU.
