i fashioned one using a gas strut(from the rear door of a van) which i had the shaft shortened to allow for only 1cm of travel. It stopped me breaking the left hand engine mount, as i had done two. (lots of launches at the drags)
My drag mate reckons it is the torque convertor winding up the trans that causes the majority of twist, rather than the engine itself. On his 9 sec 1uz twin turbo auto supra, he tethered one side of the trans to the chassis with a metal band. job done.

Does anyone know of a pulley that I can buy to fit this:

I just looked it up on toyodiy p/n 16371-50020
on a LS400 $70.14 the p/n has probably been superceded but as they were aus delivered it shouldn't be to hard to get.

Ok, So I purchased a couple of things yesterday.

I purchased an Adaptronic 440D, ID1000 Injectors,207-T1 Camshaft from Kelford cams, KVS1UZ Valve Springs and Titanium retainers.

Hey can anyone tell me how fast oil will drain away from the cam covers? I was thinking of putting my oil return directly beside the oil filler point on the cover. Seeing as no matter what my return oil has to be pumped back to the engine

Oil return from the turbo's?

I'm guessing you have to pump it from a reservoir due to them being low mounted.

Some heads (nissan) have issues getting oil back to the sump at sustained RPM, not sure how the 1UZ goes, probably safer to go directly back to the sump tho.

Check out this page on my old thread on where I put my return http://soarercentral.com/sc-forum/messages/121829/247437.html?1209974662

Hi Joshua , just reading all your post , be careful with the 255 pump in the tank feeding the surge tank , I was going to do the same thing with the forged engine I am putting together . I have been talking to a guy who does the heads and cams in Joe Geri's 1UZ Capri in Sydney and has just done a set for me , when it came to the fuel system I was going to run my 255 in the tank and 2 x 044 Bosch from the surge tank to the engine , he said NO , the 255 is to big and will end up with heat soak in the fuel because of to much fuel going through the surge tank and then back to the main tank , told me to just use a stock fuel pump in the tank to keep the surge tank full .

I'm with you guys and really don't see why everyone needs to run a surge tank , its more for track work I think or so you never pick up air , if that's the only use for it why not just make sure you never jump on the throttle unless you have 1/2 a tank of fuel or more , old school race cars never had a surge tank , most just had a good lower pickup point under the tank .
Running 2 x 044's in the tank or out in the lines would be ok , the second pump wouldn't run all the time if not needed ,it would come on slowly or if the pressure dropped below a set PSI then the 2nd pump would come in to protect the engine , only problem with 2 or more pumps is from what I have been told is heat soak getting into the fuel and then you end up with other problems .
I would just run one pump and make sure you use one of the inputs to pull timing and RPM out of the engine if the pump psi drops off below a set pressure . Give me my blown injected methanol engine any day , these EFI engines do my head in .

Thanks for that additional info guys.

I wanted the surge tank simply because I already purchased the Aeromotive A1000 pump. Factory pump sounds like it's the go. Will the A1000 ever suck the surge tank dry tho?

Just fill the stock tank's pickup pot with quality alcohol proof open cell foam and fit a good size pick-up tube, job done, no need for extra pumps, hoses and tanks, just extra weight, complexity and expensive fittings!

the Soarer tank is not like an old v8 under floor tank that lends itself to fuel slosh, no need to be a sheep with shiney bits if they are not needed!

You can get a decent surge tank made for about $50 if you're resourceful or about the same off ebay for a stainless one... You can make a surge setup very cheaply, no need to bling out with speedflow fittings...

I'm with you 100% Allan , just don't see the need for all the extra pumps ,tanks , lines , fittings , COST and work to get it all to fit . One good outlet and pump , filter and return pre pump or to the tank and job done.

Remember Joshua you are only going to use what ever the engine need as far as fuel go's and the rest will end up back at the surge take , you will need to run a line from the surge tank to the main take also , with the pump in the tank filling the surge tank and the returning fuel from the engine you shouldn't drain the surge tank if you are using the right pump for the engine combo .
This is what were saying , an easy job made complex . I made 1300hp with my SB chev and that was fuel tank , 30mm fuel line to mechanical pump and straight to the engine with return lines going back to the base of the pump . I know it a different set up and application but all still comes back to the same thing ,air/fuel and ignition .
If you have the parts then use them and if it makes you fell better to run the surge tank do it , I'm not here to tell you how to put your car together just trying to help .

It's about what is better, I think less hoses, joins and weight is better.

One of things I will be adding to my turbo v8 build is a cooler in the return fuel line, recently did a fuel filter on the supercharged beast and the heat still in it after sitting for an hour I could hardly touch the fuel filter, would of had to been 60c+, I can only imagine in your case Joshua with two turbos stuffed in temps would be even higher!
