Turbo in a "built" motor by a qualified tunerBolt on low boost kit
why? because turbo + high compression + low octane/quality fuel is not a good combination. You need quality internals too.
A knowledgable tuner can easily give you 15-20 PSI boost without issues which will definitely make you happy. Speed = Money If you can't afford forged pistons, rods, ti springs etc. be happy with what you have. If money is no concern and your tuner cannot guarantee that your engine will not be damaged by the constant 15-20 PSI boost maybe you are talking to the wrong guy because 13-15 PSI is quite normal for a STOCK turbocharged car now a days be it a WRX/STI, Evo, or Mazdaspeed.
To save you all the trouble just buy a turbocharged car.

intercooler turbos use pre-cooled exhaust gases (cool air=denser air=better fuel/air combustion) to improve hp. activates at a certain rpm depending on how it's set up.
at idle, it'll be the same as non-turboed normal displacement car because the turbo blades wind down and stop pushing air into the engine.
San po nyo balak install turbo charger? Gasoline or diesel engine, EFI or carburated.
In general turbochargers are specific for engines, they are not simple bolt-on device. The engine should be materially ang functionally ready for the turbocharger you want to install or else you will end up with a wreaked engine.
For a carburated engine here is a link for a DIY water/methanol injection device:

Upping the power/torque of a car requires equivalent improvements in your suspension, chassis stiffness, brakes, wheels and tires.
So let's say you get a PhP135k turbo kit from Speedlab and bolt it on to your Jazz or City. The way I see it, that's only part of the cost. If you want to really use the power on the road the rest of the car has to be fit to handle it. So spend the following:
- PhP67k on TEIN Coilovers
- PhP40k (est) on a better brake package
- PhP40k (est) on 17" wheels and tires
- PhP20k on chassis stiffening (strut braces, anti-roll bars/sway bars, etc)
In short you end up with a car that is easily more expensive than what you got it for.
Over at Jazz-City United we have a member who turbo'ed his Jazz 1.5. Total cost of the car plus upgrades was a reported PhP1.5M; he's selling it now on a "sacrifice sale" price of PhP1.1M.
My two cents...remember "power is nothing without control"
Turbos aren't really specific for engines, the install itself though is engine-specific or vehicle-specific. Depending on the size of the engine bay it's going into, the piping for the intercooler and other parts could be longer or shorter. There are turbos that are a better match for a certain engine than others though.
Madadaan yan sa tuning. If you don't tune a turbo'ed car well it may even produce LESS power than stock. Kaya mahal ang charge ng ibang shops for turbo installs...the extra money you pay goes into the tuning, to make sure that driveability doesn't suffer and the extra power really is generated. They do various runs on a dynamometer ("dyno") to confirm this.
Mitsubishi's TD04 turbo for instance has been successfully used in a variety of Hondas...and TD04s are standard equipment on turbodiesel Pajeros.
As for upgrading a 4JX1's stock turbo...pwede gawin yan. Aside from the complexities of the physical installation, you will have to tune the fuelling and A/F ratios accordingly to suit the new turbo. This will be relatively easier/cheaper than starting off from scratch with a non-turbo engine like your Corolla's 1ZZ-FE.
I think there are turbo kits available for these engines at least sa abroad but going back to the original question if these upgrades are cost effective, my bias is toward the losing side. There maybe other options to restore and optimize the performance of your cars.
Yung 4Jx1 medyo maselan at matampuhin daw talaga yan but try to check the injectors at sensors, dyan ata madalas magkaproblema yan, I think sir 'dieseldude' could help you with that.
Cheers po.
It would depend greatly upon what the car's owner if the turbo/intercooler upgrade is worth the money spent on it.
In comparison to upgrading using all-motor mods vs turbo upgrade to achieve similar HP targets, the turbo upgrade will achieve greater HP gains for the same money spent.
If you are just using the car to commute from point A to point B, having a turbo/intercooler will generally not be worth it unless the performance of the current car is so poor that it takes a calendar to measure it's 0-100kph acceleration time. This point becomes more important when the car is taken to areas with many tall hills or mountains to travel over.
I don't think the Jazz-City United member was happy with the upgrade or he wouldn't sell his car at a loss. A turbo upgrade will not save gas inversely it will use more fuel. The boost will depend on the turbo size (inducer). You are better off leaving your Altis as it is and not listen to outrageous stories.

The K3-VE is the Toyota Avanza 1.3 liter engine. A bolt on turbo kit converts this to K3-VET.

magkano? I have no Idea.
Consider this: from 120 Nm/4400 rpm to 170 Nm/2800 Very nice low end torque. :D
92 Hp to 116 Hp.
sir s_quilicot,
Meron po palang thread dito about 4JX1:
http://tsikot.yehey.com/forums/forum...er=desc&page=7
Bibili ka ng bagong turbo from bushing to ball bearing type at kung anong size ang kaya mong boost.
A brand new ball bearing turbo from Garrett (good for 275-350 hp if done right) will only cost $+- 600 (turbo lang more or less P25,000) Dami pang kulang for the install at ung sabi ni type 100 na chassis, brakes, at suspension. Ang chassis nga dapat seam welded para maganda kasi d kaya ng mga braces lang.

A Jazz/City with a turbo is fast but the problem is not the engine but the transmission. The manual transmission will handle the power but the automatic tranny like the CVT will simply not handle the increase in power too well. This might have lead the owner to frustration and eventually selling the car relatively cheaply.
hey bro, kung hindi mo naman ipang kakarera ang kotse at medyo konti ang budget mo, then just leave the stock engine alone. specially if your engine is a 1ZZFE.
although you can have a custom Turbo Kit made for your engine, I just do see any point of doing it.. specially if your car is only used for daily driving.
but if you want to get more HP out of that 1ZZFE, you can have a TRD supercharger kit installed. but then again, it almost costs the same as a custom Turbo Kit (or maybe more) but the HP output will be much lower compared to a turbocharged 1ZZFE. coz a Supercharger can be used and tuned to a conservative 5-7 psi of boost, while still using the stock engine internals. but the ECU has to be re-calibrated (by using a re-programmed chip, or use a Piggyback ECU).
anywayz, I would still suggest leaving the 1ZZFE engine stock OR use a Supercharger kit instead of a Turbo kit. since the 1ZZFE engine internals is not designed to withstand boost pressures (even 10-15 psi) plus it will COST A LOT to build a 1ZZFE (Forged Pistons, Rods, Valvetrain components and other related parts to do the job right, aint cheap).
but if you want reliable HP and have an engine w/ lots of aftermarket support.. then just swap in a 2ZZGE(but still, engine swaps aint cheap either!)
aite, peace.
ahmm mga sir kiinilabutan ako dun ah ..
daily car lang naman kasi yung 1zzfe but gusto ko lang sana mag increase yung performance ng engine (if ever needed) ..
anu po kaya kung reprogram nalang yung ecu? magkano kaya ..? and ilang HP kaya gain ..
and replacing headers, tailpipe, muffler will help you save on gas mileage ba?
currently K&N filter and sparkplugs palang replace ko eh ..
sa 4jx1 naman tapos nako dun sa problem niya sa injectors .. horrible story ko yun ..hehe ..
pwede rin po bang i increase ang output ng 4jx1 by reprogramming the chip?![]()
