    for one, you can possibly look at a very costly repair bill.

    simply put, the crosswind's engine isn't designed to handle all that additional power regardless if it has an intercooler or not.

    it has been mentioned in a number of threads that they have different internals.

    some few threads:

    as for 2C Tamaraw FX between 2C turbo Liteace
    or 2L Revo between 2L turbo Hilux Surf... despite the same engine displacement, the piston's shape are different. even the air filter size is different.

    he dis-regarded the engine's pressure limit for sure... maybe he could even have the wastegate removed...

    you can increase your stock turbo pressure instead. transplanting a turbo with a different size is hell work.

    but I agree with sir mazda. unless your baby is old na I would not risk it.

    but if you really want to try, kung may manuals ka, check mo na lang pressure limit. kung may overboost warning code yung dashboard, mas ok.

    but still risky Imo...

    just curious lang...

    how "low" is the max boost ng isuzu crosswind low-charge turbo? may nakapag-connect na ba ng boost gauge sa engine & read the max boost? :D

    natanong ko na dati sa isuzu yan how much it would cost and what mods will they do if I wanted to convert my 4JA1 NA engine to their "low charge" turbo version. ang sabi sakin, di daw simple yung conversion at all the cylinder liners(?) and piston rings, exhaust etc will have to be changed and it will cost a hefty P100TH as per their guesstimate. so basically, it's the same engine, with stronger internal linings(?) to accomodate the extra pressure.

    as for other turbo kits for the 4JA1, Denso offers it for $2560 in the US. (http://www.dencodiesel.com/turbo.asp). Sayang lang di ma-download yung turbo fitting instructions.

    Share ko lang po...

    I have a friend who installed a surplus intercooler and turbocharger (from an isuzu bighorn) into his 4ja1 (hilander). I dont remember how much he spent for labor but it was really expensive Yung surplus parts, na freebie nya kasi.

    We tried driving it along the nlex in the middle of the night and malaki talaga ang driving difference. Lakas ng boost at arangkada. Parang hindi diesel yung dala mo. When we tried to push the speed to 150 kmh, we started feeling strong vibrations from the engine. Thats when we started slowing down. Overall, accelerating to 140 kmh is just like driving a 1.6-2.0 gasoline engine. This happened three years ago. The vehicle still has the upgrade but the fellow doesn't floor the pedal anymore. Maximum driving speed for him now is 120.

    Lessons learned:

    If you have money to install that kind of upgrade in your 4ja1, do so at your own (pocket) risk

    You WILL have all the additional power that you need. If you abuse that power, then be prepared to either buy a new engine or meet your creator
