Hey guys,

I wanted to know... does the 2.4L engine that is in the tC have strong internals from the start?

Is it built for turbos?

 

Not really...

It was built for efficiency and economy. Then again, so was the Honda Civic.

-THE DON

 

obviously you havent' heard of kenny tran's new car. it's a tC running 600hp @ 23 psi on a stock crank. check modified mag's websitehttp://www.modified.com

 

www.scionspeed.com

 

I'd thought so...

Reason why I asked was since Toyota had the intension to supercharge it. But then agian low boost wouldn't hurt it.

I was thinking in terms of... if the car was built strong I was thinking of getting turbo kits after my mfg warranty.

 

Correction, try 30psi

This is also with extensive internal mods; port and polish, bored 1.5 over & cylinder sleeves bring it to 2.5L, new valves, rods, pistons but yes it does have the stock crank.

Scionspeed had their's @ 12psi with stock internals and that thing hauled ___!

 

I was told by the local scion parts rep that it was built with the internion of boosting, .... a lot! It's injectors are oversized the maf sensor is also oversized. most of the parts built into the stock Tc are overengeneered(sp) for durability. compare the parts list between similar toyota products and the Tc and you'll see what I mean.

 

But the tC and Camry have the same engine, so does that mean we can safely boost 10lbs in a Camry or the tC and have it run 10 yrs with no leaks or major fixes?

 

I don't know about 10 years but technically you can. Also don't forget the Rav4, we share the engine with it too (kinda makes you wonder how hard it would be to add the transfer case and rear axle to give the tC the Rav4's 4WD).

 

Then how dependable would you say a turbo car would be?

Audi, Volvo, etc. Most of thier cars comes with turbo and they have small engines too. They have to last at least 6 yrs with no problems right?

 

They might also run lighter cylinder compression than we do but not by much. Being how over-engineered our engines are, 6 years is very possible. Even after that you might just have to replace a gasket here or there, but probably nothing major.

 

Interesting... okay cool. Thats assuring.

I didn't know the RAV4 shared the same engine. Hmm... good point, I would be interested in a 4WD conversion if they have one.

 

I know we have a toyota camry engine but i think it's tweaked to get more power out of it so in comparason i think some things are different like the other guy was saying, built for POWA!

 

I noticed you said its tweaked for more power... but when looking at specs. The Camry & Rav4 have a little more power & torque than the tC. Or at least the RAV4 does.

 

Really now? DAMN RAV4!!! That's ok tC looks better HA!

 

few reasons why toyota decided to release a supercharger for the TC.


its toyota/TRD tradition to release a supercharger for EVERYCAR they have.

and

becuase of the low RPM which resulted in long stroks of the internals, its a lot easier to spool turbo's. but the block can only handle so much HP (believe its 300)

so in a sense its was meant for boost yet it really wasnt.

 

but they swopped the tC's engine

 

worng yet right...


they blue printed the engine and had it rebuilt as in new crank, new pistons, new rods, new rings, new valvetrain, new block (short block), new cams

in a sense is stil the 2az jus hella modified but its not the ACTUALLY 2az that came frome factory

 

The tC does not share motors with the Rav4.

The 2az-fe engine is in the following US models of toyotas

05 up tC
03 up Camry
03 up Highlander

 

It may be the same engine, but like a brother, it can be built differently. Different pistons, lower compression, etc.

The 3S-GTE in the turbo mr2's and celica's is almost exactly the same as the 3S-GE in the euro/jap Celica and MR2 non-turbo, but the Turbo engine has a 9:1 compression to accommodate boost, while the non turbo has an 11:1 compression to put out more power. Turbocharge the 11:1 3S-GE, and when you start hitting double digit psi, it is more mikely to go "boom"
