bigger pistons?

hey wats up,
i was talking to my bud 2 days ago and he was telling me how he bought bigger pistons for his car...he had a pro. drill his block and install bigger pistons on his ride...wat i was wondering was would it be safe if i were to get the same for my 2000 celica gts...buy a set of bigger pistons and a better crankshaft and all the works? if so would it be a big power gain? and any recommendation on any brands? thanx

Well first of all it is called boring the cylinders and reaplacing them with bigger pistons. This is mainly done it older cars like chevy's. I know that it can be done but I havent heard of anyone doing it to the celica. I dont know if there is enought space between each cylinder to safely do this. If you really want to do something buy domed pistons in and that will increase you compression ratio which would be a lot safer then boring the engine. I think there is some out there to raise it to like 13 to 1. Probably not going to run on pump gas and with the stock ecu, but I really dont know. You could get a forged crank but it really wont do that much because your engine doesnt have enough power to really need a forged one.
So if you are going to do anything get high compression pistons, but along with that you might need stronger spring and harder valves to keep this insanse amount of pressure. Also look into stroking the engine. It does just what is sounds it increases the stroke thus giving more volume to the engine because the stroke that the piston makes will be longer!

That is all I got. If you want to know more PM me. I just dont wanna type everything I know about boring and stroking your car! It would take a long time

SeeULater, you're talking about the kit from Trial. Big bucks. And I believe I read somewhere that our cylinder walls are too thin to bore it out. You'd have to have them sleeved I think. Not sure on this though, better read up.

brashboy makes a stroker kit that will bring you engine to a 2.0 but it's expensive. it comes with the crankshaft pistons and rods

or you can get the 2zz piston and sleve kits from monkey wrench http://monkeywrenchracing.com/mwr_toyota_2zz_ge_piston_and_sleeve_kit.html

That is what I thought because there are coolant jackets between the cylinders. And you wouldnt want to test your luck. I knew there was some kit like that! Yeah you would have to sleeve them.

MWR has a stroker kit too. I wouldnt suggest going over 12.5:1 compression N/A. you'll wind up having to run 100 octane all the time which will cost a grip if your car is a daily driver.

don't forget Ti rods. also consider having port work done on your head, and getting your rotating assembly blueprinted and balanced. while you're in the head, pick up some valves/springs/retainers from MWR, and keep an eye on TPR to see what happens with their cams.
