ISR Intake Manifold Review Part 2
Vložit

- I've made some improvements and changes to this manifold since it's been on the Skyline for a couple years. I ramde the coolant system with stainless hardlines and installed better fittings where I could.
thanks you saved me from a big head aches
@@r33skylineprojects59 Glad to help
This is beautiful! Well done sir
Thank you!
Great job mate!!!
Thank you!!
what did you do for the throttle cable? the one I had in the car originally doesn't reach, i got an S14 cable (supposed to be longer) but from the L bracket the cable doesnt go far enough to actually connect to the throttle body... im at a loss, it looks like our l bracket to throttle body spacing is the same...
Did you figure this out? I’m in the same situation
Yeah all intakes, even the greddy, is made in China. I've compared them and even looked into how Japan gets their parts. Their bulk fabbed in China then sent to Japan for final machining. I was able to get the Freddy to work, but still looked awful so finally decided ISR until I can get/have time to do a plazmaman one as those are fully 1 offs built to how you want it. Lead times are long af right now for them.
Question though, how is your car dealing with no IACV, the smaller one that is stock bolted to the coolant line, and how does it deal with the AAC going to atmosphere?
That's good to know and I'm not surprised most things are coming from China. Those plazmaman manifolds are nice too. That other idle air control that the coolant runs through is mainly just for warmup without an aftermarket ecu. It runs through the throttle body too so its all deleted and much cleaner. Everything is tunable with a new ecu
@@BMcGuinness the actual IACV is that one connected to the coolant. The coolant does not actually run through it. It's just a mount point. Basically the RBs have an IACV and an AAC. Found this out while browsing Nengun Microfiche. One is for idle and the other is for idle when at idle or while auxiliary components are running. You'll notice the IACV loops to the AAC that is kind of like a double IACV. Only know about this from dealing with SR20DETs and rollers as both have the IACV and AAC.
Anyhow, guess I'll have to figure out the tuning on the ECU Master if I run into an idle issue. Thanks for the info. I do like the stainless lines though. Good job!!
@@kcobabe Yes correct the AAC is the one that runs with coolant. All of us get rid of that to eliminate the eyesore and leaks and such. The IACV is just for the aux components like you said and does great still.
Thanks! Really trying to come out with an available kit for people and some great other parts for these cars and 240's
@@BMcGuinness ditto, just bought 2 large scale 3d printers. I didn't like the gauge holder I got from another manufacturer in Australia so I decided to make my own. So now I have a 5 gauge holder. I also recounted my intercooler to use tye front bumper re enforcement.
Lots of custom fabwork required on these cars if you don't like what's out there.
I would like to scan my Garage Yoshida environment control relocation kit so I can make em in pla or abs instead tye frp or carbon fiber they make.
@@kcobabe That would be pretty awesome! I'm going to be doing a bunch of scan videos soon since I got a scanner almost a year ago and working on massive projects with it. Hope you have good luck with it too
Any updates on how this held up ?
Honestly held up great, still didn't find a company to cnc bend this honestly
Did you ever start making a kit for the hard lines?
I've remade parts of my own while testing and might be into a 3rd and final version soon. Works great just looking for better fittings
@BMcGuinness thinking I'm gonna but this manifold for my s15 (has a s13 sr) in a couple weeks I'll check in in a month after I get it powder coated if your doing something like that I'd definitely purchase a set from you
@@shiftcoupe Awesome okay!
Did you ever decide if you were building more kits? I think I’m going to build a similar one. Curious what you have found are the best fittings. (And what size you used?)
@mattbuechler8005 Honestly I didn't finalize the kit because of the complex assembly and the manifold that combines the lines and goes to the radiator isn't the best. But if someone found a company that could cnc bend lines I'd start asap!
@mattbuechler8005 The line is 1/2 stainless and the fittings are compression which have been holding up but flare is the best
@@BMcGuinness are the fittings 1/2”OD x1/4NPT? I can’t seem to find the correct ones (in the last week that I’ve looked anyway)
@@BMcGuinnessalso thanks for the response! I blew a stock coolant line underneath the manifold so I said screw it, I’ll make sure that doesn’t happen again.
@mattbuechler8005 Thats always the worst. I believe I mentioned fitting sizes in one of the 2 videos at some point. The other route was going to be better rubber lines with AN style fittings which is much more repeatable
I'd be very interested in this kit. Did you ever end up making it?
I only made that one kit so far but still planning on remaking it soon!
Any one tryed a dual chamber intake manifold on rb engine ?
Not sure what you mean but they're usually oem, greddy, or isr styles
Can you make one for me
What throttle cable are you using for it
92 Maxima cable actually fits perfectly
Did you ever make a kit ? I have a similar (not ISR) intake, I'm sure its the same dimensions.
I've driven mine thousands of miles and it's started leaking only a couple drops so I'll be using different fittings for the next version actually
@@BMcGuinness Well if you come up with a kit I would definitely get one from you.
@@1970PMD Sounds good 👍🏼
I have the rb20 intake manifold but would that fit for an rb25?
I believe rb26 is the only different intake port but double check based on intake gasket fitment. I have worked on many skylines with this exact manifold, both rb20 and rb25
@@BMcGuinness ah okay. I’m hoping I can just put the isr intake manifold from my rb20 to the rb25. I Really don’t wanna buy another one lol
@@Minidonut I'm pretty sure you can, let us know!
Bring it to travis and have him mill both surfaces flat.
Solid, I should do that
You hand bend those coolant pipes correct?
Yes, a little difficult in the tigher areas
1/2" OD x 1/4" NPT?
@@darrylherbert690 1/2 Stainless lines with 1/4 npt compression fittings to the manifold. I'd like to remake this with flared ends to fittings
You have any leaks without flaring the 1/2 tube?
@@darrylherbert690 I actually haven't had any leaks since I used thread sealer and tightened without preload on them
What did you use for bottom injector O rings into the manifold ?
I'm pretty sure all these isr kits are for 14mm injectors only
I bought 14mm injectors but the bottom o ring doesn’t fit in there . Super tight
@@jakeschlichte-xl2de Some might be very tight, you used vaseline or a little oil on them?
I don’t know . There is barley any clearance on the bottom of the injector when it’s in the intake . It’s tight
@@jakeschlichte-xl2de I'm really not sure what that could be then
Figured they'd all be about the same thickness
Please let me order one
Definitely!
@@BMcGuinness how's the kit coming mate? Would be keen on one here in Aus. But I would prefer the hard lines to all run underneath the manifold. Might end up having to do some custom stuff myself. Let me know though. Very interested in your work!
You ever make the kits?
I’d be in for a line kit also 🥵 (in US)
