Finally an update! Sorry for the wait, we didn't get the fuel rail back until Tuesday 12/10/02, so we haven't really been able to do much 
Today - 12/15/02 we accomplished the following...
1) lower intake is now on
2) EGR is blocked
3) Fuel pumps mounted in tank, all lines run.
The fuel pumps proved to be a little pain, so I am going to give a small description as to how it is setup in case anyone is attempting this. Since we had 2 pumps, decided to mount them together, so they are in the position of where the factory pump was, they are ziptied together with like 6 ties
We eliminated all of the emissions stuff, so we were able to use that to our advantage with running fuel lines. Each fuel pump has its own feed line. The original feed line remained a feed line for pump #1. The original return line became the feed line for pump #2. Then we used the old line for emissions that went to the charcoal cannister as the return line. So there are 2 feed lines and 1 return line.
One of the feed lines goes directly to the fuel rail. The other one goes into the Aeromotive FPR, which then goes to the rail.
Hope someone else can understand all this info
Things left to do...
1) oil return line (we don't have a fitting for the oil pan yet either)
2) oil feed line
3) Finish up intake install
4) Permanently bolt FMIC (it is kinda a temp setup right now)
5) AEM EMS wiring
6) miscellaneous guages (EGT, BOOST, etc)
7) configure and tune.

Sorry for the delayed response.
We weren't using dual relays, however, since we are on the subject, were you using dual relays or not ? How was yours setup ?
Also, we weren't really sure how much power the pumps are going to pull, if it was going to be way more than stock ... are you able to fill us in on that ?
Thanks
And sorry, no pictures yet, I wish!!! I will have some after Christmas because I am getting my new digital camera
All info on the car can be found at www.turboforum.net/lexus
There are lots of pics of stuff and lots of information on the car, but no pictures of anything on the car yet.

Angel,
I did use dual relays for my setup. The twin pumps would just require too much power to run on the stock wiring. I actually ran power directly from the battery to a powerblock, and tapped into the stock wiring for the ign source. If you give SP a call they can send you the relay block they use, its $9buck or something like that. Then you can use the attached diagram to help you out with the appropriate wiring of your dual pumps/dual relays.
I would highly recommend using dual relays. I tried a single, however it got VERY warm, so I added the second one immediatly.
Hope that helps a bit.
REALLY looking forward to the pics.
I'm actually getting ready to pull my motor for the swap
I'll make sure I take pics of that!

Angel,
I like your progress. Congrats! However, what are you going to do for a clutch/driveline setup? Many folks have produced well over 490 Hp (http://www.moreboost.org/turbos.htm#SP63) with the SP63 turbo.
I can't tell from your profile if you have a 5-speed (I assume you do), but that tranny has been known to break as low as 400 Hp. Additionally, the stock 5-speed clutch will probably slip unless you get a new pressure plate/clutch plate.
What are your plans for the driveline?

quikturbo - thanks for the info and everything. I am going to make the phone call to SP tomorrow and give the rest of the info to my mechanic and I am sure we are going to use every bit of it. If you have any other suggestions on ANYTHING, feel free to hook me up! Thanks again.
motorheaddown - yah, using the stock 5 speed tranny and stock flywheel. The clutchnet clutch was broken in 1,500 miles before we started the turbo project, and it should hold tons of HP, now it is just a matter of whether or not the tranny will hold up.
From what I read, it is very controversial. Some people claim to break trannys at 400rwhp, some people claim over 500rwhp. I have seen the SP63 dyno 670rwhp, and I am pretty sure that if I even get close to that, I am going to have tranny probs, however, I think if I am in the 500rwhp range, as long as I am not slamming gears constantly, it SHOULD hold up, but that is wishful thinking, only time will tell.
Hopefully we shall soon see

I talked to ComputerWiz a while ago about the 5-speed, and he said it's 3rd gear that's the problem. Due to the open differential, one wheel typically spins in 1st gear when under heavy load. By 3rd gear, the wheels have good bite; so the tranny is the next weakest link. He went through at least one tranny (possibly two) due to 3rd gear giving out.
Good luck!

Angel,
I suggest you read the following from the Supra forums thread concerning crank walk:
(http://www.supraforums.com/showthrea...threadid=56195)
It applies to anyone with a strong aftermarket clutch that puts stress on the crank thrust bearing.
Easy prevention is to bypass the clutch pedal switch.

I appreciate everyone's interest and their help.
motorheaddown I will take a look at that link and relay the info and go from there, thanks.
As far as what tranny is in the car, I don't even know It is the stock tranny that comes with an SC300 in 1993.
We might get some more work done on the car tomorrow, I am not sure, but if we do, I will post the update
