I don't know if anyone has ever tried this, but if not can you guys think of any reason it wouldn't work...this is only for dohc VTEC.

Instead of using some T-fitting adapter in the oil pressure sender hole or adding a costly sandwich adapter to get oil output, is there any reason the plugged hole in the head usually used for LS/VTEC adapter fitting can't be used to feed the turbo? Just put a 3/8NPT-4AN fitting in there, you could have a shorter, cheaper, easier, more reliable feed line...at least that's my theory. I thought this could work with DOHC VTEC blocks by drawing off the internal oil passage feeding the head.

 

That will work...thats the hole I use to feed my turbo but I think you will need a 3/8 NPT to a -4.

 

Cool, thanks...I think I may use a 3/8 to 1/8 reducer bushing and run a 1/8 hardline all the way to the turbo and skip the AN fittings w/braided lines.

I will be running a t3/t4 non-ball bearing turbo on a stock B16, do you use a restrictor, or would you know if I should use one and if so what size...thanks!

 

You don't need a restricter

 

pics of said setup?

Thanks, I'm happy to know that, it will make the setup even cheaper and easier than I thought. I can get a brass reducer for a couple bucks at Home Depot, and an unbent 1/8 hardline (I think they are supposed to be for brakes) at Murray's or Auto Zone for like $5 or so, they come in several lengths and I'll just bend it to shape. Since I have a total budget of under $1000 for my turbo setup, going from like $50 down to $10 for the oil supply helps!

I don't have pics since I just thought of it, but since PHDZINE has already done it perhaps he will grace us with some photos? I will take some when I'm done though.

 

this is what you want http://store.summitracing.com/...w=sku

that connects to the vtec head at the 3/8th opening on the dizzy side. you can use it for ls/vtec conversion kits or you can tee it to feed the turbo and run your ls/vtec conversion its simple and reliable.

 

Yeah I saw those, I have been researching what might be the best way, also what would be most cost-effective. After shipping costs that fitting will run me about as much as the whole setup I concocted. Since the head is NPT, and the turbo is NPT, I wondered why should I convert to AN lines/fittings then back again. The aluminum fittings and stainless lines can get pricey, even though they look good. And I don't really need anything versatile or with T-fittings, It's already a stock VTEC block so I just want something simple to run turbo.
But I did think of the same idea you had for using it for LS-V and turbo simultaneously. Actually there is an adapter fitting I found on Ebay that has multi-port output so you don't have to stack an extra fitting on there.

 

I hope you are not talking about the pressure check port on the head.

No not the one in the picture in that link you put up. The one everyone uses for LS or CR-VTEC next to the intake manifold. See below pic where I circled it in red...

you can buy 3/8th to 1/8th npt adapters just search on google they should be around $5~$8

 

this is actually in the plans as of right now for the next turbo set-up...

 

there is a smaller 1/8 port toward the bottom of the head that could be used as well
copper color plug @ the bottom, under the dist mount location.

Aha, I didn't notice that little thing under there, that would be even better to not use a 3/8-1/8 reducer bushing, make the line a few inches shorter and make it less noticable. Thanks for the tip.
