how much hp can be produced with ct9 on stock internals

[FLi_GTi]

160 hp . (not at the wheels)

[rozzzzz]

@fli
just 25hp more then stock and no more use of stock turbo

[rozzzzz]

which turbo can be replaced to get maximum power on stock internals

[FLi_GTi]

The CT12A off a 99 3C-TE is a good replacement and is a bolt on fit save for the fact that its compressor housing needs to be rotated 360degrees to face front. Reliable 1bar plus performance!

[lowresolution]

The Toyota E series was never meant for performance .! its for economy ..! so if u want a real performance / affordable engine go with the 4age ...!!
I personally prefer honda`s line up of engine over toyota`s for swapping ....coz of the much better aftermarket support ..

@roz
The stock CT9 runs out of breath at around 16 psi ...! which`ll be probably be around 170ish hp at the flywheel ...


@Fli_GTI
As far as i know , the only ct12 which is worth upgrading is from a Supra ...! and that does not fit bolt on ...!

Also , if someone wants a real upgrade for the 4efte , the TD04 series is widely used all over the world.....but it should be backed up with fueling mods etc .....

[FLi_GTi]

@Lowres.
Firstly the CT9 does'nt run out of breath at 16psi, the small wastegate gives you surging issues bigger still, reliability is the 9's biggest issue. Secondly, the 3C and the 1J use the same turbine (latter models on the 3C). The upside to using the 3C's turbine is that you can use the exhaist flange to the manifold and the the down pipe at the same time. The job requires less than 30 minutes.

@Fli
come on man , both engines are different , 1 is patrol and the other one is a diesel ..i hardly doubt both will have the same turbo charges !!
2ndly ....how much do you reckon ct9 would go up to ? people all over the world agree that above 16ish psi ...ct9 just gives out hot air ...

[rozzzzz]

@lower

thats was the point i had in my mind about CT12A

[rozzzzz]

@lowresolution

how much encomical is stock 4efte

and 1 thing to ask...converting a 4efe into 4efte do required changing internals..as i have seen on some forum saying both engine have diffferent internals..like connecting roads and gas kit .pistons etc

[alihashmi]

@Rozz...


thrz a diffrnce in compresion of 4efe and 4efte....


other thing u will need to change is Wiring which includes Map sencor ,Ecu Distributer and all....

[FLi_GTi]

They're the same, I should know, I've owned both . 5blades on the compressor, 9 on the impeller for CT12As. The CT12s on earlier versions use 4 blades on the compressor and 8 on the impeller. A turbo's a turbo, does'nt matter if its on a diesel or petrol (e.g. the TD04 used on the 4M40/1 is also used in .8 petrol variants). As far as the CT9's concerned, the CT9's been used till 17-18 psi with a wastegate port and actuator contrary to people claiming shaft disintegration at 14 psi.

[rozzzzz]

@fli_gti

rdo u still own any 4efte setup...or if u did in past as u said ..no how much psi and in which car

[REDZDEVIL]

Finally.... Here too....!!
Gud Luck Bruv....!!

[saadzae92]

very nice thread , i'll also join in

@rozzzzz




Sir 4E-FE and 4E-FTE are worlds apart from a performance point of view. while the 4E-FTE might look like a Turbo was bolted on to a normal 4E-FE but the truth couldn't be any more further from it , alot of meticulous attention was given to the internals of the 4E-FTE , because it has to bear the grunt of a Turbocharger, so as Turbocharging basics go firstly the compression ratio(CR) of the 4E-FE was lowered from 9.6-1 to 8.2-1 to avoid detonation, this was done by using slightly flat head pistons and using a thicker head gasket (1.2mm) the combustion chamber was same as the 4E-FE (combustion chamber volume=39cc's) as the same cylinder head as the 4E-FE was used alongwith same lift and duration camshafts as the 4E-FE , secondly slightly "beefier" conrods were used to survive all the 135 horses @ 6400rpm to a redline of 7200rpm , the fuel delivery system was almost identical to the 4E-FE with the exception of 295cc injectors in the 4E-FTE as oppsed to the 195cc injectors in the 4E-FE , to ensure that all the air provided by the Turbocharger has sufficent fuel to burn. also the crankshaft pulley had a harmonic damper instead of a normal crank pulley, to further ensure the longevity of the cranshaft by reducing torsional vibration. so thus the 4E-FTE is a stronger and powerful member of the E family of Toyota engines.

@ FLI and Low


both 4efte experts, and my opinion is 4efte is a very good engine. parts are available in paki. and cheap upgrades which will produce some good power.

[farhannk]

Whats the cost of this engine,. and can it be fit in to Corolla 1980??

[lowresolution]

@roz
You cannot exactly convert a 4efe into 4efte ...coz as saadzae92 stated that both engines are quite apart from one another ...!

However you can have the 4efe turbo`d using the basic bits and pieces from 4efte ( electronics , turbo ) , how do keep in mind that max boost you`ll be running on the 4efe internals would be around ....0.4 - 0.5 bar at most .... !


@7650
upgrades are not cheap etc at all trust me ..i know ..coz i have 1 ...

@farhannk
under 50k for a complete engine ....keep in mind that a few bits ( ecu / map sensor etc ) of 4efte are quite difficult to find..
