Mark II Engine swap to 1JZ-GTE Turbo Engine

nitrousFiz · Post by **nitrousFiz** » Wed Dec 21, 2005 5:27 am

Holla guys,

I'm very bummed today coz the new 1JZ-GTE engine that I want to get from Japan wont fit my MARK II GX100 chasis. There goes my dream of 280hp sports sedan.

The problem is that the engine mountings are DIFFERENT in my GX100 chasis to change the 1G-FE (current) to 1JZ-GTE (swapped) enngine.

I need your help guys! I'm sitting wid the £2000 cash and no engine!
Help me find a workshop who will modify the mountings and help me fit the 1JZ.

Alternatively, I can custom turbo my 1G-FE engine, but is it possible in dhaka? Any contacts or suggestions will be very appreciated.

If I cant make sure that I can fit the engine in Dhaka, then its no use importing the engine.

Seriously guys, help me out! samar, rawfin and others post some replies plz..... your help will be really appreciated....

nitrousFiz.....(very bummed)

Sorry to hear that.... a well-known DTD member told me that one can fit 1JZ-GTE in Altezza... which uses 1G-FE.... engine mountings have to be modified... there is a '93 Corona with 3S-GE... my cousine's '78 Corona have 3S-GE with Turbo........ he have installed turbo in '97 Starlet & his brothers '91 Corolla.... so first u decide what will u do.. swap or install turbo.

thanks for ur reply sakin bro.

my first choice will be installing TURBO in the 1G-FE since it is less of a hassle.

I can get really good turbos from Japan directly, but do you know who can install the turbo in the 1G-FE in dhaka?

hope so.... if they can install turbo in 3SGE.. even in a 2A-U (AE90 Corolla) so hope they can install in 1G-FE... but u will need to swap some engine parts.. well i have no idea what they r .. but to absorbe the presure of turbo.. u need to do work on engine.. plz pm WRX.. he might give u some idea..

I'm sorry to say that I cannot give you much info because I have no experience with turbo charged Toyotas. I have 2 turbo charged cars - one subaru and the other mitsubishi. Both had turbos from factory - one I modified later after blowing the original engine (subaru).

Since the GX100 is a JDM (Japan domestic) car, I am afraid you will hardly obtain any info from English speaking countries. So, you will have to look to Japan for tuning work on this car. This I won't recommend, unless you have very strong ties to a Japan based exporter. That is because of the following reasons :
1. Adding a turbo to a normally aspirated car :
For this you have to add a lot more than just a turbo. With the turbo you are adding more air into the engine, for that you need bigger injectors to match the increase in air intake, a bigger fuel rail to carry more fuel, a bigger pump, an intercooler to cool the hot compressed air, and a new programmable computer that will work with the existing electrics. This is the least you need. Out of all this the tuning of the computer (which controls ignition timing and fuelling) is the most important aspect otherwise the car will not run properly. But I don't think there is anyone who can tune your car in Bangladesh, unless you have a microtech about which I have some basic tuning knowledge as I use one.

2. Installing a turbo charged complete engine :
Even this will require proper tuning after installation otherwise you may find you have thrown money into a car that runs poorly and will be so unrelaible that it will give you a lot of grief in the long run.

Now, comes the problem of dealing with Japan. Whichever you go for, turbo kit or engine swap, you need constant contact with someone who has done exactly the same thing before on the same model, so that he can provide solutions to all the eventual problems you will undoubtedly face, because he has faced them before. But, the Japanese hardly speak any English. How do you get round that problem ?

Sorry to disappoint you, I have to suggest you forget about ruining the car you have, try to save up to buy a an original factory performance car, turbo charged or V-tec engine. Then after some time at factory power, you can modify it later for more power when you get bored. In that case, buy a car that is exported to English speaking countires from whom you will get good support - say from tuners in the USA, UK, AUS, NZ, etc.

thanks for the input WRX. new engine or adding turbo - none seems to be an option anymore.

i just want to make my car go faster. wat is your opinion on nitrous injection?

i heard almost every car can handle upto extra 50hp (shots) of nitrous. but nitrous refills seem 2 be the problem.

any help on where i can get nitrous tank refills in dhaka?

I have to discourage you from nitrous as well. Nitrous works because it has more oxygen content than air and by making the air intake cooler, therefore, denser - increasing the number of air molecules. With more air you need more fuel to keep the air/fuel ratio correct to keep the car running properly and to extract maximum performance.. Now, how will you add more fuel ?

In a wet system it comes with extra fuel injectors, in the dry system you add more pressure through the stock fuel pressure regulator on your car. BUT, if you don't keep the pressure/temperature in the nitrous bottle constant, the amount of nitrous injection will vary - running too much or even too low pressure could destroy your engine in seconds as too rich will increase cylinder pressures and too lean will lead to severe detonation. You could also get low pressure when your bottle is running low on nitrous. Then, you have the problem here with installation and refill - what grade of nitrous will you get here ? So, not really worth the hassle and danger in my opinion.

I was once pretty serious about installing it in my Impreza. In a turbocharged car the effect of nitrous is doubled. So, a 50hp shot will actually give you 100 hp increase as you can run more turbo boost due to the extra cooling you get from nitrous injection. BUT, the potential risks far outweighed the gains so I left it out.

LoL, seems like i'm running out of options.... I contacted a performance store in Japan - they also discouraged nitrous as it will kill the engine in months anyway even after proper use...

For now i'm gonna stick to minor mods like upgrading:
1. Exhaust system to 3" pipes with hi-flow CAT
2. DENSO Iridium Spark Plugs
3. Strut Suspension
4. Wheels with slick tyres
5. Intalling an EVEN BiGGeR & better induction system
6. Sports Thermostat
7. NOS Octane Booster

And wat else? cant think of more stuff..... any ideas?

Regarding Nitrous injection-

I actually contacted some local nitrous dealers (in london) and checked out the internet for more information and found out-

1. Fuel Delivery- Stock fuel pumps can deliver upto 40hp extra fuel when required.

2. Dry System- using a dry system with 35hp nozzles should be okay since stock pump can supply upto 40hp extra and the trans will take upto 40-50hp extra.

3. Nitrous refills - difference between grades of nitrous is that the automotive grade has an additive for smell (Hydrogen Sulfide) so u know when it leaks, otherwise it is the same as medical grade. So medical grade can be used in cars just as effectively! I just have to contact the local dentist or hospital 2 find their supplier. lolz!

4. Bottle Pressure- adding a bottle warmer jacket and monitoring the bottle pressure effectively for refill will solve this problem (they do come with a pressure gauge). its all about maintainance. plus adding a purge kit will remove the gaseous nitrous from the lines and allow fresh liquid nitrous from the bottle into the engine for a "harder hit".

5. Installation - this is the part i am least worried about. not to mention that all kits come with comprehensive installtion guides plus I have read quite a few installation walkthroughs in the web and it does seem pretty staright forward for a DRY SYSTEM that I am goin for. i figure that any good workshop mechanic will be right for the job!

Finally, most people fear using nitrous since they want to run high shots of nitrous like 50-75-100hp, but in my case running only 35hp does seems okay, doesn't it?

Nitrous makes the most HP per $ or £, and the risks after getting the right stuff for nitrous does not seem extremely high in my case. Does this still seem like a bad idea?

The store selling you the nitrous kit will not take any responsibility if you face any unintended consequences. My tuner would have made some money by selling me a fully loaded WET kit, but HE discouraged me. He does it for a living and he's installed it in many cars he has modified. Since I spent a lot of money on an engine package from him, he wanted his engine to give me lasting pleasure, so, for his reputation he would rather make a little less money than have an unsatisfied major customer So, beware !

you can also go for broke and try modifying the engine mounts... which is still a very bad idea

or you can try fiddleling with the engine internals, bigger bore intake, and if you have the money to burn have your engine cams bored from japan, and get forged connecting rods, aftermarket pistons, cam sleeves, cam shafts, drop in a MSD ignition system, high performance tranmision. Brake upgrades... bigger fuel injectors with a fuel management system or chip your ECU(piggy back ECU) I feel that improving the engines response and power with out installing a turbo is very rewarding in a big car. Raw naturally aspirated power is pretty awsome aswell. You can scrap the automatic and drop in a manual tranny and get performance clutch and flywheel kit.
