1jz how hard is it???

we have enine mount from right hand supra and it has some defect. that is why we deside swap engine on modify engine mount...rakkasan said:
P.S. Engine pillow i meant rubber round pillows thats conect paws and mount
P.P.S. sorry for my language)

Yep pretty much on the engine side.
The body side will need about 15+ 1 time only splices to your jumper harness. Mine haves only about 15 but if you have other systems like pps hydro fan and abs so on it adds to that also i removed 2 wires that where just looping in and out of the connector it was the oil level warning system.
It had 3 wires going through the connector you only need 1 that red/yellow one just loops in and out the same connector. The yellow/blue one that goes to the sensor is the only one you need if you keep the sensor like i did.
I had so few splices to do after removing PPS ABS Hydro fan Cruise Control A/C complete system etc.... that I removed only 2 wires that were left in the White connector that i needed and moved them to a 25% empty Gray/Conector so now my swap & harness haves only 2 Connector to mate up with the body.
15-20 1 time splice jumper cable is managable and there is no shielding on them.
I had to splice 2 wires by the fuse block to go with the alternator that was it maybe total max of 20 splices.
The PITA way is easily well over 200 especialy inluding shield jumpers. Will also set your swap back a lot of time if you want i will let you see how to do if you live in the So Cal area.
proof you can use hydrofan parts (high pressure line) for the replacment power steering line on a 1jz conversion.
I think i rearanged the union bolt and couplers with the 7m left over parts but here is how it is configured go from here.

I think the hydrofan pressure line would be much better when used as.......the hydrofan pressure line on a working hydrofan. The hyrdofan pressure line has been known to fail, why use it on your power steering?

proof? who said you couldnt? This reminds me of when you posted that thread 'HAAYE GUYS, proof you dont have to extend the harness!'

It is a power steering line! The hydro fan system.
People dont realize that the hydro fan is a verry parasite design sucking hp away from the engine it is an extra power steering pump just pushing a remote fan thats all. Its complicated looks ugly takes up room and is heavy, takes away from your water pump also.
Use the alternator most of its over generated energy is filtered and regulated back to ground the left over unused energy. Just use that wasted energy thats allready potentialy there to run a e-fan.
more theory below lol.
"Its like inventing a perpetual design by having an electric motor hooked up to an electric generator and saying you just spin the electric motor 1 time manuely and it generates enough energy to spin the generator and then spin the motor more. Endless process."
The irony of this is only people that believe this above theory love hydrofans.

I dont claim to have invented the wheel but when you should be dring round tires on the road and see people use square ones saying extending the harness is better you would hope to try and save people and help them thats all no HATE here. I am not insecure about the past post of other people 6 months ago trying to bring them down and throw down hate and discourage good ideas like some is there something wrong with me? I think i know what it is you extended your harness and blew up a couple ecus doing it wrong or know people who are taking longer trying to tackle the harness extension and you believe people must go through hell like you did to do there swap that must be it.

I know you are all excited about learning about cars and stuff, and you want to help others, but slow your roll there cheif.
What most people REALLY don't understand is that added load on a alternator also causes the engine to work harder to turn the alternator.
The horsepower required to turn the alternator is dependent on the load on the alternator. Electric fans pull a lot of amperage, electric motors are not 100% efficient, and alternators are VERY inefficent (only around 50%). Your perpetual motion comment is nonsense.
The loses of an electric fan are comparable to the hydrofan pump. The hydrofan is also variable speed, so in fact, it requires LESS horsepower to turn it when the engine is cool then a fan that is on 100% then off, and the hydrofan can better regulate the engine temp. A hydrofan on full speed also has probably 3x the cooling capacity of a dual 11" electric fan setup. So basically, the hydrofan kicks ass over electric fans in all situations you motor will be subjected to. All the horsepower you think you are freeing up by using a electric fan is being consumed by the alternator, plus some. I would venture a guess that the hydrofan is at least 10% more efficent overall then electric fans.
The real irony here is that you offer a whole lot of advice as of late, but most of it is misguided, or sometimes (as in this case) complete
misinformation.
Here is some good reading on alternators and such:

I hardly think the hydrofan is 'ugly.' I like it alot because no one usually has heard of it so they go 'OOOOOOOooo what's that.' lol... looks alot better than some E-fan with exposed wires though...
parasitic loss? ohnoes! a few horsepower. Probably less than the difference between a hot day and cold night...
and no i didn't blow up any ECUs so try again. My harness is just fine, thanks. I didn't go through hell for my swap. It wasn't any harder to put my 1J in than a 7M. Maybe you're the one who went through hell blowing ECUs with a crappy extended harness. :ugh2:
oh and aaron ftw

i agree. i like my hydro fan. I think it looks better in the engine bay than the stock 7m clutch fan and shroud. all things said and done i wont loose any sleep over a few lost horsepower to keep my 1JZ cool... :icon_conf
stanzaspeed said:
I agree too. A hp or two loss can be remedied with just a turn of the knob... :biglaugh:
lol true, but im running on my wastegates right now so no knobs for me. i just live with what i got
