ic and intake piping

[lowdown]

Ok, standard 240z with 280zxt (stock) motor in it. Looking to order some 2.5" or 3" exhaust mandrel piping to make all the connections. I don't have a IC yet (just working on getting it running first, will work on that in january) but I'd like to order it all now, including the intake piping. I do lots of welding/fabing but this turbo stuff is new for me. Debating on ordering 2.5" or 3" for it all, should I just go with 3" so upgrading is easier later?

 

Thinking of ordering a few of these

Also what would I need for the connections to the turbo, IC etc. Can i use the spetra ricer crap from vatozone?

The 2.5" ID tubing should be plenty for your i/c since most cores use have 2.5" inlets and outlets. If you're shooting for 500+hp then you may consider 3", but most likely that will just be overkill and will make finding a core a little more expensive. As for the autozone tubing, it will work just fine. Aluminum piping will help dissipate heat a little better, but for a budget you can't beat the exhaust stuff. Couplers are one of the main areas that you really shouldn't skimp too much. You can buy quality silicone stuff from

http://www.turbohoses.com/ for pretty cheap, and they even sell the t-bolt clamps to secure them. Make sure that when you're fabbing up the piping you (or have someone) run a bead along the rim of the pipes so that the couplers and clamps have something to keep the pipes from blowing out of the couplers under high boost.

 

And for i/c cores check out the godspeed (or whatever the ebay name is) cores. They are way cheaper than all of the big names (greddy, spearco, etc.) and usually perform almost as well. Just make sure the cores are bar and plate as opposed to tube and fin, and you'll be fine. Hope that helps.
