Smile 2003 350Z LS Conversion

Hello everyone I'm finally building LS 350Z��. It's been a very long time coming but here we go. I bought the conversion kit from Sikky including their Master cylinder, 1 7/8 headers, solid rear bushing, wiring harness and power steering line. The computer is out of a 2002 camaro wich makes it a dbc. As of now the engine and tranny are put in and all the rest is left. I'm trying to keep things on a reasonable budget since I'm having a house build. If you gents could please gid me the right way with the rest of the parts that would be great. Oh and I need to replace the fuel tank. The one that's in there is dirty as heck and no one in SA will clean it. I need to find a solution for a replacement. A stock one is priced at $700ish. Here's what I need of the top of my head
- speed hut Tach
-fuel system
-catch can's
- radiator and fans
- rear exhaust
This car will be a DD so AC is going to be put in. If you gents who have done these swaps help me find the parts I need or some in site on some does and donts that would be great. I'll post a pic as soon as I learn how lol.

That tank really isn't very old. How dirty is it? Can you clean it out with a siphon pump a few times?

It's pretty bad but I'm thinking giving it a go myself. To bad they don't make an aftermarket tank

I believe POR-15 and Eastwood have fuel tank cleaning (restoration) kits.

Your gonna probably need a custom radiator unless someone is mass producing them for the Z swap. and as far as the fueling...............just gut the spare tire well and mock up a cage for a fuel cell. Ive got like $150 in my setup (LS6 swapped 04 STi)...Even reused the stock sender and walboro 255 to keep gauge functions stock lol

There are a lot of LS swapped 350Zs out there. Google search and you will find all kinds of build threads on various forums. Whatever your thinking about doing, has been done 100 times and the answer is somewhere online. Start searching!
