The long awaited transformation, 1 car 1 decade 1 dream Options

[coldbluesteel]

Hello everybody. like it says... this is the story of my Celica's transformation. This will be an on going thread so if it needs to be moved go ahead, thanks. I'll post pics when I get a chance. Great things are on the horizon.


The goal... to have the meanest street driven Celica in the world.

Details will be added soon.

That's OK - I'll take cash,.... how much you got in that wallet ?




"But really though I do see your point on the 3u."


-snip -


It's the ONly way to go for a Lex V8 - the 1 UZ is a money pit with little to offer
other than cheap initial availability - after that ....... WoW is it Expensive to
get 'right' - and a major let down without.




Ok I did some more reading.


milnersXcoupe- I do see that the 1g is a nice motor.

The 3u does have some pros too, but it get its extra power from the VVTI.
It seems like I t would be easier to build up with out VVTI, or am I wrong?


-snip-


Well, yes. The VVTi changes the intake track runner lengths to optimize the air flow for a given RPM -
which helps HP / Torque as well as mileage and emissions.

MOST of the increase comes from the HUGELY upgraded Intake Plenum / Intake Runner / Intake Port / Larger Valve / Combustion Chamber reDesign / Piston Crown design / Piston Bore Increase > 85mm to 91.5mm !!


I can understand people building 1u's if they have 1 stock but there are lots of people dropping them in other cars too.


-snip -


Yes, agreed.

But why ? Cheap availability, WoW factor to look at initially - BUT - every single 1 UZ user complains bitterly about the Intake / Bore / lack of Torque unless the engine is Turbo'd - and then they hit the problem of the Entire Intake Tract being 'choked' - so they port the Plenum - swap it out for a later version - port the runners - port the heads - bigger valves - then after thousands of dollars and tons of time - realize they should have used a 2 UZ top end as it breathes much better in STOCK form than does any Hyper Ported 1 UZ top end ?

Ain't done yet! Then it's Cams - and the motor is STILL not as drivable as a 3 UZ would be just off boost -
you want an engine that is GREAT off boost - then a 'FREAK' ON boost........ THAT is where it's AT !


The GR engine is the Wave of Toyotas Racing future - as the cylinders are COMPLETELY surrounded by coolant - so Turbo and Supercharging will NOT bring on all the headaches of hot spots that the FORD Cobra camp are experiencing:

That engine weighs 384 lbs. - it LEAVES the line Flying!

The V8 guys are there waiting for the motor to make power and lifting
150 more pounds coming from nothing to RPM - Lite Weight = Torque !


Read those Racing Posts above - they went from a MAXIMUM EFFORT
Turbo 'Blown' 4.7 with GS400 heads etc. - set new Track Records -
then went to a TOYOTA V-6 adding Turbo - and went FASTER !!


Even the 5.7 - which is *Sweet* for a Normally Aspirated engine -
is NOT suited for Supercharging / Turbo , as it has Siamese'd cylinder
liners > Hot Spots <, and Alloy Melts around 1100 degrees > Turbo engine
combustion chambers see 1250 + ........ so tell me what comes next ?

Cylinder bore distortion and broken piston ring lands......... no thanks.
