as far as the oil fitting on the block, I know that Rob at Descendant sells one that is a direct fit for the tC block....one that dosen't cross thread. Give him a call!!

The kit I'm installing is actually the descendant kit...I wonder if that fitting comes with the kit....I guess I'll have to ask when I call them to order this weekend.

That part threads into the block perfectly! I just threw it on and had some leakage, but some teflon tape will take care of that...

Yea i just clicked on it and it says account suspended as well
Well here is another link i found: http://www.pegasusautoracing.com/gro...D=PLUMADAPTBSP

As long as you go to google and type in BSP to NPT adapter or fittings, a few places will show up.

But yea the block is BSP threaded so we need these in bulk for the boosted scionlife community.

For what it's worth I would like to contribute my experience and solution

After visiting skinnayy to see his install I saw his feed line was plumbed 1/8 NPT into the block.

Despite reading this thread I tried to fit 1/8 NPT but could only get in 1/3 a thread before it came back out with a sliver of aluminum from the block.

I ordered the NPT-> BSPT from JEGS ( http://www.jegs.com/i/Auto+Meter/105/2269/10002/-1 ) and the damn thing still didn't fit.

I had a close look at the stock pressure switch and compared to the existing NPT adapters I tried and the JEGS, the Stock pressure switch appears to have a slight conical taper at the threadbottom, the JEGS piece was dead straight

The solution: I threaded the JEGS through the back end of a 3/8 NPT die to take down the starting threads (it was either that or tap the block.) To my surprise the part threaded in perfectly! (not loose, not overly snug) Added some teflon paste and got my T-Fittings in. So far 50 miles no leaks, not that I expected any but it's always good to check.

so now we know if you are getting a BSP to NPT fitting, it has to be a tapered BSP male thread.

Woops! Totally forgot about this thread haha,


Well those two parts posted in this thread work together great as I stated.

So, this splitter- http://www.glowshiftdirect.com/1-8-n...g-adapter.aspx, which costs $18.53 shipped. Plus this adapter- http://www.vgauges.com/catalog/produ...8a4f293da45845 which costs $14.75 shipped will allow you to tap your block seamlessly.



The third "port" is currently plugged up, it's going to be for the oil return line when I install my kit in a couple weeks. That plug also comes with the splitter.



Also, I had to use teflon tape because at first it leaked a little, but now it's been on for over a week and I've done some heavy driving on it without a single drop of oil.
