just wondering if anyone has got the intake manifold off before to polish or something else and just wondering how do you get the wiring out of between the pipes of the intake manifold. there is a pic of the what i mean.

Are you wanting to take the manifold off completely or just replace a head gasket? Reason I ask is because if you are doing a head gasket you can just unbolt the manifold and slide the head off the other side. If you are wanting to polish your manifold as per the above good luck because removing the manifold completely is a complicated process. If you have mechanical/electrical experience you should be able to fumble your way through it. Its like anything it will probably take 10 times longer the first time lol

When I did my my build I put a heat resistant gasket on. I also put an pen gasket either side of it which I wasn't supposed to do so I have to now remove the own gaskets. I figure that I can just unbolt it and slide the manifold on the two remaining studs and cut the oem gaskets out but I fear that I might have damaged the heat resistant gasket and may have to remove and replace it which would require the complete removal of the manifold. I'll just get started on it and see how I go. I think the hardest part is going to be removing the loom so if anyone has some pointers on that that would be very helpful.

I tried to remove mine before taking my engine out because I thought it would make taking the engine out easier, I did it with no prior experience or much knowledge in removing the engine or manifold.
With some parts of the loom unplugged, I could slide it out a bit and let it sit on the studs.
Removing the whole manifold would mean disconnecting the loom from the ECU, passing all the plugs through the firewall and then through the manifold.

basically you have to undo 90% of you loom. From your alternator and coil pack loom to the gearbox loom and all the sensors that side of the car and the connectors that go to the fuse box. Also your coolant sensors on your water outlet. If you have all options after i done mine i found would be quicker to take the motor out. If you dont have the abs unit back there would make it 100times easier to get to everything

Aaron has a good point, the loom just as most things are easier to take it out while the engine and gearbox is out. But I reckon just see how you go, just remove enough plugs to give you enough slack to get enough to the head.
OH and also, some of the plugs and lines that you may need to disconnect under the manifold are going to be an absolute pain in the ass to get back on, it looks like spaghetti bolognaise.

yeah sure does i was really disappointed about the toyota engineers when i tried to do this. i mean how hard would it have been to make a slot in the manifold between the runners!!

I'm disappointed that the toyota engineers didn't put a 2J in, in the first place especially for the price they were charging and the weight of the vehicle.
I'll try and pull it back first and cut out the oem gasket, if that doesn't work I'll have to pull it out while taking lots of pictures as I go.
Has anyone used Hylomax gasket joining compound before?

2j with turbo's couldn't make more power or they would have had to de-tune it. The max power the gentlemens agreement which was enforced through the 90's included cars could have no more power than 206kw. Hence why there's always speculation that these vehicles made more power than what was on the spec sheet.

Torque is what you need to get off the line, especially with a low stall converter hence why I want a 2j and anyone who thinks that the 2j is only 206kw hasn't driven one before. I would estimate they would be closer to 220kw+ the extra torque.

You run a suncream business. It costs 14 dollars a gallon to make sp 50 sunblock or 30 dollars a gallon to make sp 100. The govenment comes in and says "You aren't allowed to call any sunblock better than sp50".
You consider your market and realise "It's too costly to make a sp100 for 100% of shipments because it'll be twice as much as our competitions products. But a few informed people might still look beyond just the label rated and find out that it's still higher quality. Lets make 90% sp50 and 10% sp50+."
Extreme example, but it's about cost benefit versus market perceived value.
In japan in the early 90's toyota;s cars like the celsior and soarer were the japanese equivilant of the BMW. How informed do you think the average 5series owner is of their horsepower? Not much? What about the m3 or m5? They probably do.
Has nothing to do with torque, or actual real life. It has everything to do with the company being a business and understanding the people who buy the vehicles.
If you want to be upset at anyone about the fact that they have a 1jz model at all, complain about the ill-informed first buyers of the cars.

I get what you're saying Austen, the extra torque alone wouldn't have made it any more attractive a car to buy on paper but once you take it for a test drive which I'm sure everyone does before buying a brand new car that off boost torque would have made the soarer a much more worthy competitor to the m3. I also doubt that it would have cost much more to put a 2j in but I may be wrong.
Also, they put the 2j in the Aristo which I'd imagine was directed at a similar target market to the soarer so why does the cheaper car get the better engine?
