3sGE unboostable?, Dont burst my little bubble... please! Options

[markjbutler]

Hey all,

not been here long and reading around the very few posts about boosting the 3sge it seems that it either a) isnt a good idea or b) just simply shouldnt be done. I've read up on wiki about how turbo systems work and also looked at the differences between both the T and non-T versions of the 3S and bar a few parts in the bottom end and compression ratio there aren't any discrepencies - correct?

so... with a standard compression ratio would it not be possible to boost the 3s just at low PSI? As far as i understand it the whole point of boosting is to force more air+fuel into the chamber i.e. artificially raise the compression ratio to rather giddy heights so therefore starting at a higher ratio could be seen as a benefit as you could use lower pressures/smaller turbo i.e. faster spool up times (i'm yet to get into what the hell A/R and all that palava is).

I may be way off here - dont be too rude on this n00b!

p.s. going to refurb my alloys tomorrow hopefully, black wheels on a silver celica acceptable? i'm thinking black should be the hardest colour to get wrong (although they cant look any worse than they do now)

Cheers if you are still reading!!

I think you have the right idea and you say you don't care much if you blow the motor. Under those conditions, if I was you, I'd do everything the 5S-FTE guys are doing but with slightly lower boost and if you use everything stock 3S-GTE [CT-26, Manifolds, etc] then you will be able to use that stuff on the next motor if you do happen to blow it. At that time just drop in a proper 3S-GTE and you're good to go.
Read Pressure2's sticky on how to turbo the 5S exstensivly. Read up on the differences between 3S, 3S-GTE, and 5S.
You can do it if you really want to, and I say good luck to you on breaking new ground. I remember when the 5s was considered unboostable and "not worth the effort"
