I understand there is a good location to tap into an oil source for the turbo in a B18C1 block. where is this? Any pics would be helpful.

I don't really want to use the oil pressure sender since I will use that to T off to provide for my Oil pressure gauge and really don't want to double T there.

 

I think there's a metric fitting that goes in you oil pump where you can run your oil sender from...
it is the actual 1/8" NPT.try z10, I think they have one for 20 bucks..

 

Its not that easy to get to the oil pump, is it? Looking at the Helm book, I can't see where that would be.

 

I found the z10 product. any idea where exactly that fits in? any tapping needed?

 

I think there is a port you can tap into near the vtec solenoid. Someone on here has done it.

 

i remember seeing that a while back. I couldn't find it with a search.
The Z10 fitting seems like it would just screw in somewhere but they don't describe the location. I'll have to look at my car tomorrow to see. I'll try calling them tomorrow too.

 

There is a place to tap the line directly beneath the VTEC Solenoid. I tapped mine there and it seems to work fine. Easy as hell to get to and everything. I'll try and get some pics of it up tonight

 

Is that the place they sell the fitting for? I assume when you say below the VTEC solenoid that it is in the block rather than the head, correct?? However, the Z10 fitting indicates the oil pump and that is on the other side (timing belt side) of the engine, right?

thanks...pics would be very helpful

 

Also, I heard rumors that tapping that location only provides oil when the vtec solenoid is activated. Is that true or not?

 

not true. It gave me oil when cranking the engine with no spark. SO i would assume it would have oil flowing at all times.

 

Chris, you have an Integra? please provide some detail as to where you got you line hooked. Did you have to tap a hole or is there a ready made bolt hole?

 

there is a pretapped hole with a bolt in it. It looks like it goes to nowhere. I'll try and get you a pic up tnight. depending if i have a USB cable here

 

I just ordered one of those from Z10. It should be here tomorrow. If I'm gonna T off a connection I would rather it be in a location less prone to vibration and the oilpump fitting may be a better location. then I can have my turbo feed and pressure gauge right at the same spot and leave the factory oil sending unit alone.

Apparently the bolt on the oil pump is easy to get to and the guys at Z10 were surprised no one had marketed a fitting for it previously!

 

I know, I thought it was a good idea for the oil pump...
lemme know how it goes....my kit should arrive anyday now and just trying to get everything ready as much as I can...

 

depends on your set-up but the pressure from vtec solenoid may be too high for your turbo / return line. oil pressure sender on block is what i use now, the head gave way too much oil pressure for my set-up.

 

The bolt on the front of the head is the oil pressure test port. The pressure
there should be the same as jsut about anywhere else in the system.
The oil pressure in VTEC engines is higher to begin with anyway.
Also, the VTEC solenoid only allows pressure to the vtec system. This is
drawing oil from the same source as the vtec solenoid, but NOT from
the solenoid itself, or else the oil pressure would be there only when vtec is
engaged.

I have heard that restricting the oil flow is a good idea. Any thoughts?

 

don't tap it from the oil pressure test port. There is a allen head plug right under the distributor, tap it from there. It has british pipe threads though. THe oil pump is not filtered yet.

 

is there a reason to not tap it from there, or just a general preference of yours?

 

Correct, the oil pump is unfiltered!!
I will probably use that point for my Greddy oil pressure sender and use that one under the distributor on the head to send to my turbo. I'll have to tap it for NTP and i should be ok.

No T's or anything to worry about then.

cool.

 

Its on the .summitracing.com web site under books (this is the earlier and better version).

Shows the VTEC-solenoid area oil tap location on its cover (they claim to make 477 hp at the crank on a 18 psi built bottom end GSR motor), and discusses the oil pressure at that location as well as some hardware ideas for doing the plumbing.
Good appendicies in the back with engine series info such as bore, rod length, stroke and model years for the various Honda motors over the years.

tell us what the book says about the pressure there. Does it mention the allen bolt under the distributor and the oil pressure there as another possibility?

Is there pressure near the vtec solenoid too high like others have said?

 

hey i have that book ..dont know where i put it after i moved tho

 

I got that book and the volume 2 so I will scan through it and tell you guys what I find by tomorrow....

 

I have both of the books. They have pretty cool theory in them but some of the information is outdated.

Its not an allen bolt, its a plug.
