I was just learning about fittings and such and ran across a very informative post at Honda-Tech. Wanted to share this picture, its a setup with two braided stainless lines running from the back of the block to a “T” on the firewall where you can place your oil feed, the stock oil pressure sensor and either a plug, or an additional oil pressures sending unit to an in-car gauge.

Hope this helps someone!
This is an order with part #'s from:
Like this?
Very much Stu…although, how much did yours cost?
I was very impressed with $45 price tag from mcmaster!
For the lines and all? Or just the fittings and stuff?
xenocron- Good find. I just ran a fitting off of the back of my block, then a dash 4 line to my T fitting (where it has multi ports for my feed line and sending unit). From there I run a dash 4 line right to the turbo.
How are you holding up the “T” though, since the whole point of mounting it on the firewall is to reduce weight and vibration from the block.
As long as the T is not mounted to the block your fine. There is no stress on that line at all. The weight of the T in conjunction with the vibration of the motor when running causes it to snap if its attached directly to the block. I tie strap the main feed line to my master cylinder. So there is no stress on the line or T fitting, and because its braided line. Its flexible to move a little bit if the motor moves when shifting or stopping.
So you just tie it up some where, where it holds the line up enough to not cause strain on the block?
Zip Ties work wonders!
xenocron, that is def a good setup, but for 20-30 dollars more, you can save alot of headache and get the GE adapter. There are 2 1/8NPT ports as well as one for-6. I have em on both my cars and will never use anything else, cause they are nice and easy.
The GE adapter might be $20-30 more…but then you still have to add the cost of all the lines and fittings…and it doesnt make it any easier or safer to install.
My T for LS/VTEC is right on the block…no problems yet. I have heard of people putting on an autometer oil pressure sending unit and snapping it right off…that thing is BIG and HEAVY. Anybody recall what size the stock oil pressure sender is?? I seem to remember -4AN…any help? Thanks!
Size of the sender? -4an is the size of a hose not a sending unit. :bang:
The hole in the back of the block needs a male 1/8" BSPT fitting.
nice. i want to use the tranny cooler section of my auto radiator as an oil cooler.
what about line pressure to the turbo? are you guys using restrictors and what are the pressures like with our b18a’s?
Whoops…I knew that…sorry my plumbing/fitting size/terminology isn’t as good as it needs to be.
So what’s the difference between “NPT” and “BSPT”???
I believe the taper is the difference between the two…
[B]Tapered vs Parallel Threads.
If you look at male NPT threads, you will notice the diameter of the fitting is tapered, narrowest at the end. Parallel threads do not have a taper. The most important thing to understand is that tapered threads form a seal differently than parallel threads. Fittings with tapered threads seal on the threads. Use teflon tape on these type of threads to help make a good seal. On the other hand, parallel threads can either seal against a gasket or oring–do not use teflon tape–or on the threads–use Teflon tape if you want to seal on the threads. Garden hose thread GHT is another example of a parallel thread–the seal is made against a gasket—don’t use Teflon tape. Bulkhead fittings, shanks for beer faucets, and the couplers for our picnic coil coolers have parallel threads–the seal is made against a gasket.
Gas regulators connect to cylinders thru parallel threads. Do not use teflon tape.
Why does NPT work with BSPP?
Take as an example 1/2"NPT vs 1/2"BSPP. Both have 14 threads per inch so they match up quite well. The primary difference is in the pitch (angle of the thread) which is 60° vs 55°. Use a little teflon tape and they screw together and seal just fine. I was surprised that 1" NPT worked with 1"BSPP because in this case the threads per inch are different (11.5 vs 11). I think the reason they seal is that you don’t use many threads to make a seal, perhaps 4 or 5. 3/4"NPT should work well with 3/4" BSPP as well since the threads per inch is the same, 14.
[/B]
Makes sense. I would assume that all threads on the block and head -for example stock water temp senders etc- are all BSPT spec?
I would assume that Honda would follow the BSPT standard…i believe NPT is an american or military standard.
Good find XDeep
Hey xeno (or anyone)- I’m about to make an order from mcmaster (thanks to you). Got a question for ya- All of your fittings are 1/8" yet the PTFE hose assembly is 3?16" That does fit the 1/8" fittings, right? I’m assuming that follows the ID/OD pipe size chart thing. Thanks!
