Best turbo upgrade for toyota 3c engine

[zed2d]

Mga Sirs what is the best turbocharger that will fit the 3c-t engine without changing the pipings because i want to add more boost to the diesel like 8psi or more from stock. thanx in advance

hey bro, have you tried upgrading your Intake and Exhaust system? also, do you have a Boost Controller? (or even a boost gauge to monitor boost pressure??).

anywayz, if you dont have these upgrades then I think you should have these basic mods before replacing your Turbocharger on the 3C-T. also, its not a good idea to "over-boost" a diesel engine (8-10 psi over stock) since the engine will not run efficiently. not unless if you want to spend more money on engine internal upgrades & engine management upgrades (which I think is not worth doing, specially on a 3C-T engine).



aite, peace.

I assumed you already put intercooler in your ride right?

I don't know what turbo to replace, but I know that 2c-t CT12 is swappable with 3c-t CT9's.



but I do not recommend upgrading your turbo. your ct9 is capable of producing boost even up to 13 psi or more

like KBR suggested, increase boost by using a boost controller. or plain cheap washer. though 3c-t has boost fuel compensator, you need to manualy adjust to a little more fuel.

buy a boost gauge to see not to get it exceed 10 psi. (readings must be tested while the engine is running hard or uphill) I recall I mentioned before to a similar thread that 12psi is the max but I was wrong. 10 psi is the max and 13 psi is the check turbo alarm indicator. contrary to a friend from uk that he get's 12 psi regularly in his diesel. autodata suggests 10psi. his 12psi data is probably for Starlets, Gtti's.

You dont have to upgrade your turbo, a cheap way is delaying the openning of your waste gate. Like kBR said a boost controller can do this. Ingat lang sa pag increase ng pressure, your head gasket ang pinaka maapektohan niyan.

Modifying or changing your turbo for an additional 8psi of turbo boost will not significantly improve power as this is only air. Power gain will be marginal. To gain more power, the injection pump has to be readjusted to deliver more fuel as well. But this is not calibration; this is modification. And you will be running the risk of damaging your engine. The 3C has ample power as stock.

Ingat.

I realize your stock engine used to be 5K from a local liteace right?

I'm noob with muflers, is your intake, exhuast, mufler for 1.5L gas engine compatible with 2.2L Turbo Diesel?

3CT has bloody vac and boost pipes. are you sure all of the pipes are properly routed?

your Injection Pump has two valves for the vacuum and boost pipe to connect for fuel balancing. it should have 5 actuators. and your TPS should be working too.

thanx sa mga reply ninyo mga sirs. by the way yung intake ko pala i modified na ang airbox chinange ko from the oiriginal to a isuzu elf airbox plus large pvc pipings. and i added an intercooler from a isuzu trooper. and lastly my exhaust is already turbo back free flow 2" diam pipies. And i've already adjusted the full load adjustment screw in my injection pump to its fullest. sir rion how much pala yung ct12 na turbo? and what boost controller should i get for this type of turbo?

This is very interesting but off topic: I know of somebody in Colorado who is a dieselhead and goes by the name of Zedd, and here you are who seems to be similarly interested in diesels and your handle here is ever so slightly different

If the device that compensates fuel input per amount of boost at the intake has not been adjusted then I think you need to check it in order to achieve optimal air/fuel mixture. Remember a larger turbo will create more lag due to the larger components.

I think the best turbo upgrade would probably be a VNT - variable nozzle turbocharger

[rion]

interesting, full na yung governor? dapat lilipad na yan. but how is your fuel consumption? and smoke levels?

no idea how much ct12 costs. whole engine kasi kami bumili.

I believe there is something missing in your mod and transplant. considering full yung governor. a stock setting is halfway lang.

you are using a intercooler for 3.0-3.1L TD engine but the engine is 2.2L + longer than stock pipe routes. and specialy NO boost mods, that's a huge lag.

I will this stress again because your engine is a transplant and a partialy electronic controlled fuel. Your boost fuel compensator valve in your injection pump must be routed properly. without it, no fuel compensation during boost. happened to me when we had injection pump cleaning. the mechanic was not able to return the pipings properly and it was disastrous. A working TPS (throttle position sensor) is helpfull. it also balances air/fuel mixture. were you able to make it work?

also, for further improvement disable your EGR. gives you a little more pony power.

any mechanical boost controller will do fine. haven't used one personaly though. I am using plain cheap washers lang, not as efficient...

*mbeige: VNT is the ultimate satisfaction. but I bet the turbo costs more than the engine itself.

[mbeige]

*Rion, I didn't say it was the best one, financially

I have a CT20 TOYOTA, I bought it so i can study its dynamics yung nagaaral pa ako. I dont even know kung saan siyang engine naka mount.

Meron din akong 4AB1 VE pump, kaso was to scared to open it then fearing hindi ko mabalik ng tama and nga components. Balak ko sana donate sa school pero tuwang tuwa ako so I kept both.

bro rion my tps was broken by my mechanic when he installed the engine. about
my emission there is no visible smoke except from accelerating from standing still there is a little smoke. just would like to ask any of you guys what tachometer should i use with this engine and how do i wire it to the injection pump sensor?
because i want to achieve 160kph and would want to know at what rpm could i achieve this because for now i could only achieve 140kph * unknown rpm but thats with a 235/45R17 rear wheels with 215/40R17 front tires from original 165SR13. thanx

[mbeige]

If you know your transmission and final drive ratio then you can probably compute what RPM your engine should be running at any given speed. It would be ideal to make a blocking plate for the EGR piping, not just disabling it because it can be disabled in the open or closed position. While you're at it have the manifolds cleaned too.

TPS would help a lot for your injection pump to determine what the proper amount of fuel should be injected. Maybe you can even modify you IP to get larger plungers if you want to go that route.

I would imagine that a Toyota Lite Ace van would have a very low final drive ratio to achieve good acceleration so your RPM's at high speed would be really high and noisy too. On my diesel the final drive is 3.07 and at 100mph/160kph the RPM is around 4,600. At 110mph/180kph it's around 4,800RPM.

ey tol, I think you should try a 2.25" or 2.50" turbo back exhaust. since ang 2" is like "stock" and medyo restricted pa din.

anywayz, as for a Boost Controller, just get a Manual Boost controller. either from Hallman, Turbo-XS, Perrin, etc.. OR you can shim the Wastegate but before that though, make sure na may accurate na Boost Gauge ka (either from Autometer or VDO.. both brands are pretty inexpensive)

aite, peace.

140kph with 17" mags is good enough considering your didn't have it hook with the computer box.

a normal full govenor (which 3x 12' oclock turns) would have you pull on the edge of your seat even on half throttle. I have done this myself on our 3ct a/t without mods pa yun. but the smoke is hard to disregard and the mileage is bad.

3ct pumps are tacho hook-able, but finding a electrician that can hook it could be hard. if they cannot do it, hook it in the alternator.

and yes, I meant block the EGR. as mbeige was saying...

will help eleminate lag due to the space allocated for the egr pipe. and no more inhaling back it's utot.

I have no idea if this will help you, a friend from uk sent me this photo to help me install back the right 3ct pipelines.

bro rion talking anout wiring the tachometer to the alternator how do u do that? and what kind of tachometer is that so i will just D.I.Y. it. And just would want to know what is the fastest speed you've drove your liteace?

[4JGtootsie]

Wala ba abang sa transmission?

[rion]

sorry bro, I would like to know myself how to connect the tacho on the alternator. sa loob kasi nag-ta-tap ng alternator ang mga electrician. I hear autogauge for diesel will do.

I would like to know myself the top speed of the ride. but I had a car accident 6 months after I learned to drive. my driving foundations today is based on fear. kaya hangang 115kph lang kaya ng puso ko.

Alwayz Yummy was able to get 140kph with his stock 2CT 4x4 automatic tranny liteace though...

Sirs. I am planning to change the engine of my dad's Tamaraw FX with a 3C engine. I'm a total noob at engines and mods. Mahilig lang ako magbasa ng mags at manuod ng Discovery Turbo :D

Anyway, as a gift for my dad, papalitan ko ng makina un FX nya. May sentimental value kase sa kanya yun.

Do you have any advices as to what the best engine is to buy as replacement? May nag-recommend na 3C and it's worth around 45k. Sulit na ba to?

Ang objective ko is to have that FX restored like new and change the engine. Thanks!
