Absolutely no performance parts on 3s-ge vvti Options

[Beams]

What the hell is wrong with people? Is the 6th gen so unpopular? I'm loonking for Pistons and Camshafts particularly for the Beams engine. Does anyone know if anyone makes pistons or camshafts for beams? thnx

The real reason the Beams doesn't have many mods... wasn't because the 6th gen celica isn't popular...but it's because the Beams is simply a very rare engine. As far as pistons go... the Beams pistons are already very performance oriented... I forget exactly, but I think the Beams has a compression rating of 11:1... already much higher than the 3rd gen 3sge... The easiest way of upping the compression ratio is to prep the head... shave it.

As far as cams go... you can always do a re-grind...but you'll lose VVTi as west_minst said. You'll probably gain a better top end, but typically, if you do a very agressive grind, the lowend department will be very harsh... unsteady idle... pinging and knocking possibly...

Now... for the disagreement part... Don't go turbo on the Beams. It's such a beautifully designed engine, that was not built for a turbo. Its block is hardly as strong as the 3SGTE block and its very high compression ratio will make it very dangerous to run even modest levels of boost.

The difference between the Altezza beams and the Celica/MR2 beams is the VVTi design. The celica/mr2 has VVTi on only the intake lobes, while the Altezza has it on both the intake and exhaust. It's not just the cams that are different, I believe. I would imagine much of the electronics and the heads are both slightly different...
