The second set of tapped holes are probably there for the ISF tranny which looks like will work perfect for you.

It's awesome that you have a rebuilt LS1 with no car to put it in and of all the options, you chose the IS250 as the candidate

Good luck with the project!

Thanks SB350. I'll post my engine build pics when I find some time but right now it's hard to divert my attention from the swap. Your car looks sick, the wedssport wheels are on my short list right now, just not sure if ill have any money left once the swap is done.

Looks like a great project!! LSX swaps are so popular these days... I sold my LS1 FD RX7 about a year ago...

I did some more work on the clutch pedal placement, fuel system diagnostics, and brake system planning.

First, I wanted to track down the fuel lines. I am planning on using a bypass style fuel pressure regulator so I need a supply and a return line. I don't have any specs on the IS250 stock fuel pump but I am going to give it a shot unless I discover that it's not adequate. The pictures below show the fuel line locations at the fuel tank as well as the engine bay. There was an extra line in the engine bay that I tracked down to a unit underneath the trunk. After a little research I found it that it's a fuel vapor canister. Something for emissions. At this point I don't know what I am going to do with it so I'll have to do some more research.

Engine Bay Connections

Fuel Vapor Canister (To get an idea of the location, you can see the exhaust where it splits to go to each muffler in the background)
Click the image to open in full size.

The IS250 brake controller is huge and in the way of where my clutch master cylinder needs to go. I also don't think it would work properly without the inputs from the engine so I have decided to pull the system. I'll most likely install a brake proportioning valve in it's place.

Brake Controller, Now you see it...

Now you don't. I have a few marks on the firewall in the background where the clutch master will penetrate the firewall.

So is that not the ABS unit you are removing?
