Forged crank? The pistons sure arent

by **Mr Revhead** » Mon Jan 29, 2007 3:52 pm

yeah the crank
and iirc the pistons are.... will check the set we have at home tonight
certainly didnt look cast

by **Prymal** » Mon Jan 29, 2007 5:32 pm

Semi forged if i recall , like the 4agze pistons

Theres a specific term for them but i cant recall it atm

and they will hold around 350 - 400 HP , but the question is for how long , till either your rings go , or your headgasket goes pop

If your looking to push the stock engine , at least double check headstuds and head gasket , the crank and rods will see that figure fine.

So 3SGTE pistons are semi solid forged? How come they break so easily then?

Bad state of tune

by **flygt4** » Mon Jan 29, 2007 7:06 pm

dont spose they are the same or similar material as 4agze ones? 4agze pistons take some pretty serious abuse to break.

i ran mine at 20psi for a while after i replaced the turbo with a new one the exact same, turned out it flowed so much more not being damaged it made the a/f ratios dodgy as hell. thought it felt faster :oops:

turned out it needed a shitload of fuel added into the tune on the dyno. seems to have survived tho

its only the real wrc motors though i belive...gt420 had some for sale for a while

Those are about the only differences between that engine and any other Gen III 3S-GTE, and they don't even work

and ct20b turbo. yamaha head

The CT20B is stock on all Gen III 3S-GTE's, the only slight difference is the export models got the steel turbine, even the Japanese WRC models got the ceramic one that every other JDM Gen III had.

There's nothing special about a Yamaha head on a Toyota, it's stock on all 3S and a lot of other engines. Yamaha are Toyota's design partner and have been developing heads for the for the last 30 Years or so.

For about 30 Seconds, until the ring lands give up and cry enough :evil:
