Been busy with life but i'm almost done with the fuel pump. Should be finished tonight along with the inlets.

Only thing left is to find a permanent solution to the steering rack (Fast intentions gave me the basic idea which actually solves my problem) but they weren't willing to give any details or sell it for me.. So i will have to make it myself. I could actually tune the car as is since the downpipe doesn't leak when it's missing 1 bolt but i don't want to leave it like that.


Another exhaust video for you guys! The tone actually changed somehow and now i love how it sounds.

Getting close man!!! Bummer that FI wouldn't sell you their spacers...
I agree it's a good idea to to make sure you get three bolts on the downpipe... don't want it to start leaking when the motor is rocking and rolling.

Is the spacer something you can have machined?

"This video does not exist!" - YouTube

Fixed it for ya.

Thank you! For some reason it shows on my phone but not on a computer

I understand your dilemma on the steering rack but FI is going to give up their proprietary engineering to anyone. You can't stay on top if you give share everything. It's that they don't want to help you it's about their bottom line!

I totally understand and I appreciated that they even let me know that they use the angled shims on their kits.

Hopefully it won't take me long to figure out the angle. I already got all the dimensions and length needed for the spacer, with just the angle left to figure out.

Yup. Wouldn't be good business sense.

Right on...that is very cool!

I am good with whichever direction they choose - as the IP belongs to them so they can do what they want.. I just prefer the CJM approach. Seems like any return fuel system you buy from almost any Z vendor includes some CJM parts.

Maybe if FI took the same approach, then a bunch of turbo kits would use their spacers (or ICs, or manifolds, or whatever)? I don't know if the idea would be applicable in this instance and is certainly not usable universally. Just saying - there is more than one successful approach out there and the alternative in this case brings the most good will and does not need carry as much risk of copycats since most copycats would rather just buy it from you than reverse engineer it. (Just speculating here, I am no business expert)

edit: This reminds me of an episode of those old Biker-Build-Off shows.. I remember one of the builders also sold all the parts he designed and coincidentally the guy he was competing with actually ordered a headlight from him for the show-build. He was like "Even if I lose... I still win."

Sometimes selling components can cause trouble.

Just as a made-up example, but one possible scenario: Perhaps their source on the spacers is slow or unreliable. They might only have a small amount of them available at the moment. If they had to push back a turbo kit sale because they sold off a set of $25 spacers... no good!

Certainly... just wanted to point out that there are alternatives and since you are probably 1A/1B on everyone's list here along with FI, you made for a good example. =)

Im still waiting on that free S1.SE fuel system you sarcastically promised me somewhere. ITS DOCUMENTED! =)

Sorry husam, I'll stop shooting your thread off topic now.

Yeah I totally understand their point of view. I certainly wouldn't give away the design of any of the adapters i worked so hard on to finish.

Anyways, some good and bad news.

The good news is I have been experimenting with angles and it looks like I figured out the exact angle needed to clear the bolt for the downpipe.

I also scheduled an uprev tune at a performance shop a couple hours away from me. I will probably rent a U-Haul to tow it there or something.

Bad news but not so bad is after removing the fuel pump, I figured out that I had to buy the CJM install kit for the aeromotive pump.

I thought that it wasn't necessary but it is. I will be ordering it tonight so hopefully I'll have it finished asap because it stinks now!

WOW this thread delivers!! Mad props for following though.

GT-R turbos on the VQ37
 

Just doing a few things while I'm waiting for my fuel pump install kit.

Anybody know what these do? They fell as I adjusted the steering rack.

Finishes installing the fuel pump and it still idles fine.

One thing I just caught is that the low oil pressure light has been on since the first day I started it!

I'm hoping it's the sensor gone bad and not a different problem because It was a perfectly running engine before.

I'm ordering a pressure gauge and installing it instead of the oem sensor.
I'm hoping everything is well before my dyno appt 2 weeks from now.

This might be the last and final post I make on here.

Bad bad news. The oil light that went unnoticed by everyone including myself turned out to be very real and not due to a damaged sensor.



After the initial panic, I opened the turbo feed lines and I found oil in there.

Turbo drain lines? Nothing there but tiny drops.

Turbo inlets? Dust on the driver side :(


I guess I'm in denial at the moment but the worst case scenario is probably what happened.

No oil pressure due to something magical, followed by the turbos oil starving and the engine grinding itself slowly (it still sounds perfect somehow)

I will drop the pan tomorrow to see if that is the case. I will post back on here if I got lucky by an act of god.

Thanks everyone for your support along this dream project of mine! I couldn't have gotten this far without you guys.I guess I should of listened to the older members on here so I wouldn't be in such a horrible situation.

:eek:
Dude I hope you find something that is not terribly expensive. Best of luck mate.

:(

Say it ain't so...say it ain't so! Sorry bro!

Would like to know what happen. What was the cause?

is it a 09?

Opened the downpipes and dropped the pan.. not a single thing blocking the pickup tube and somehow the turbos still feel healthy with no resistance and no shaft play.

Any ideas why there was no oil pressure?

Oil galley gaskets are a common problem.

I dont know at what pressure the oil pressure switch closes. I will see if I can find it in the service manual. Perhaps you only had very low pressure rather than zero pressure. If the engine was only at idle and not being driven, it doesnt take much oil pressure to sustain. How much was the car driven or run with the light on? It sounds like it might be possible that you dodged a bullet. I have seen engines last for years of abuse after brief oil pressure mishaps.

I actually hooked up a mechanical guage (cheap tester) and it didn't move at all which is what worried me.

I doubt it's the gaskets since that's a pre 2012 problem i believe. I also find it weird that the oil filter gets filled as soon as i crank it but the pressure gauge never shows anything. It's almost like the oil never comes back from the filter.

Only thing left to try is to remove the sandwich plate and try it with just the filter attached to the engine. I just have to order the shorter oil filter stud.

Oh man... Hope you find the issue.

A stupid question - your oil pan spacer came with a matching oil pickup spacer/gaskets, yes?

I'm not sold it would be the OEM oil cooler sandwich... since it hasn't changed for this install... Also, I have taken mine off... it is a pretty simple device and seems difficult to clog.

Hope you get to the bottom of this soon, i've got my fingers crossed the motor is still healthy.

Good news! Finally found the problem. Somehow after removing the Mocal sandwich plate and getting the pre '12 stud, it works perfectly. Approx 100psi of oil pressure at idle.

The turbo return line was opened though haha so I have to clean up that mess tonight.

Crossing my fingers that the turbos and motor are still healthy

Did you have the thermostatic Mocal plate? If so, that thing is bad.

Yes that's the one I have. Unfortunately was with the car when I bought it.


Sent from my iPhone using Tapatalk

And what are you basing that on?

It has a thermostat inside that opens up. Not sure why this happened. I would have to take it apart to see. I have one on my car and would like to know myself.

I think the way you worded it - it sounded like you were saying the Mocal plate is bad in general, not that this particular one is bad. =)

I think tons of people are running Mocal plates and are happy with them... unlike the Mishimoto trash.

victorious.

Friends don't let friends buy Mishimoto.

Someone needs to tell that to Trips and AK.

I think I got super lucky on this one but time will only tell.

Just ran the car through 4 oil changes (cheap oil) just Incase there's any objects but looks good so far.
Oil pressure is approx 100psi on a cold start and 45-50 psi at 2000rpm when warm.

I'm going for a final oil change just after the base tune with M1 0w-40 (GT-R spec oil). I'm thinking that it's a little better for an engine on boost.

Currently I'm just waiting for some 2.25 piping so I can finish the inlets and install everything back on. Base tune should be next week with Ecutek.

This is good news!

But, I am still confused on the Mocal therm plate. I just put one on my car a few weeks ago. The valve is partially open most of the time, and if it stuck in either position you should still have oil pressure.

More info on the filter and sandwich plate failure would be helpful for those of us who run it.

Husam, reading your posts makes me belive you have removed the mocal plate and the oil pressure problem has been resolved?

I was a hydraulics system design engineer for over a decade.

I am thinking that there are two failure modes in the the mocal oil cooler/ filter system that could explain your low oil pressure concerns.

1. Blocked oil cooler or oil cooler lines. If partially blocked, only a small volume of oil would flow back to the filter inlet side (across the thermo bypass valve), effectively causing a big pressure drop in the system.

2. Blocked or damaged oil filter. Definately this condition would be a problem. Cutting the filter open would reveal any malfunctions or manufacturing problems with the filter. Filters designs have an internal bypass to prevent pressure loss in case of element blockage, so this does not happen very often.

I would check these two items out before reinstating the oil cooler system.

Sorry I haven't had the time nor patience to dig in deeper considering I have probably over 150 hours in this project. I'm going to assume installed error before calling it a failure on the Mocal plate since it's very hard to literally get 0 pressure with it installed.

I did try two filters on the sandwich plate and both had exactly 0 pressure. I even unbolted the sensor and started the engine, but nothing more than a few drops came out until I took off the sandwich plate.

I will let you know as soon as I figure it out.

With a Mocal sandwich plate, oil flow to the engine cannot be stopped.
The thermostat only restricts flow to the cooler, it does not restrict flow to the oil filter.
If the valve is jammed open oil will flow directly to the filter, by passing the cooler, then back to the engine. If it is jammed shut it will flow through the oil cooler first, then back to the engine via the oil filter.
In either scenario the oil returns via the oil filter.
The filter would be my first suspect in this situation.
Husam, did you change the filter when you swapped sandwich plates?
Just a bit concerned for you that the fix was a coincidence & it may happen again with catastrophic results.
Here is a link that explains how these sandwich plates work, it probably explains it a bit better than I do.
Cheers.
