2.0 upgrades
Is anyone goin to do this mod? whats our celica gts compression ratio on stock? Cause from what i hear from the shops here is that 13.2 and 13.7 to 1 is very high and can blow up our motors. I want to do this mod but i dont want to mess up my engine. If anyone is goin to do this mod please give me details on what i should do to not make my engine blow.

Ha ha, I don't think i'll be messing with the compression anytime soon.


Knowing the path and choosing the path are two different things.

th3 2zz can handle 31:1 compression just fine, but you7'll have to run racing fuel (98+ octane) if you stick with the factory ECU.

If you get brash boy's 13:1 kit, it comes with a new ECU, and will run just fine on premium pump gas.

31:1 sounds high, you sure? thats almost triple it's stock compression. are you sure that no engine reinforcement is needed (i'm thinking reinforcement.

I have an '03 GT and I swapped my pistons out and went with weisco 11:1 pistons, and crower rods. I went with higher compression because I knew I didn't want to go with any sort of forced induction. angry...Remember that if you go with a higher compression ratio (13:1) that you can't run any kind of boost in the future. Having your engine built costs a pretty penny, and if you ever get the itch to run boost, you won't be able to run it safely without spending a ton of money (again) to have lower compression pistons put in...so just be sure

thats a very good point
plus you can get more power from lower comp. pistons and higher boost
