It all depends on how much boost you plan on running. If you want to run anything over ~7psi, you'll need to lower your compression, whether it be with pistons or a head spacer.

Sorry I haven't been around in the past couple days but here is my answer to your question.
When I boosted my car that was my biggest concern was the compression mine is 9.2:1 which is high for a turboed car where as many turboed cars are running 8.5:1. I have ran up to 14psi on my car with no problems(but i don't recomened this for everyday driving) but around town I run it at 9psi and i'll tell you that is plenty for killin rice rockets. I don't know the exact compression ratio of the tibby's but if it is around the 9.2:1 ratio then you should have no problems with running 9psi safely I must also add you don't want to run under 92 octane in your boosted car it kills the performance.

AT 14psi HOLD ON TO YOUR SEAT, IT"S GONNA BE A WILD RIDE !!!!

The 2.0L beta runs 10.3:1, the 1.8L runs 10:1.
You can run up to 10 PSI if you have an intercooler, but beyond that you will have to lower the compression, or rework the head/pistions.
Onpol managed 227 HP at the wheels on a dyno with 10 PSI with stock compression and pistions.
I have the Alpine turbo kit, it comes with a "spacer" to increase the distance between the head and the block. While not Ideal, this lowers compression to 9:1, and should allow more boost. I am currently running at 10 PSI.

WELL SH I T, Looks like after reading some of this stuff I might need better pistons ( forged) and cams and **** if I wanna run more than 55 SHOT witout problems. I was talking to my friend troy who has a EX V-tec A newer model and he says he can run 75 Shot , but hed have to replace **** within a year. So I was like so your gunna run around 50-60 Shot and he was like "yea, if I ever get a system, I told him to go with venom." Hes also getting forged pistons. for his **** , this is probably the most honarable honda owner I know. He used to have a maro and he knows how to fix **** up. So I was wondering if they actually DO make aftermarket pistons,cams,rods,blahblahblah for my type of car. I told him a reason why I got a hyundai because I knew it would be a CHALLANGE to fix up, because i was going to get a 96 civic untill I steped inside and felt the power of hyundai. But IM a domestic man, Hydro and forged pistons were a luxtury we had the first day we got our cars because they were everywhere. same with honda. you can look anywhere and they have anything from freakin custom ciggerette lighters to the ricy pin stripe body kits. I dont find that very challanging and kind of boring. I got hyundai because I knew parts were scarse but **** man if you look hard enough you can find ANYTHING for them. Hyundai is making a great come back from the 80s and honda owners still have that bad reputation.

Lantra,
They do make all that stuff (HKS in Korea), but it's very expensive, and it's for the 2.0L Beta, not the 1.8L. If you wanted pistons for the 1.8L, you'd have to get them custom made cause I doubt there will ever be enough demand for them to put them into production.

Lantra,
Go here to http://www.rpw.com.au and email them about getting some forged pistons for the 1.8L Beta. They have it listed at AU$900 on the site, which is about US$468.
