Accusump is installed and plumbed into my oil cooler bypass

I plumbed my oil pressure gauge into the sandwich plate by the oil filter.

Heres a pic of the thermal bypass plate

In other news the hydraulic lifters in my IPP heads are pretty loud and knocky .

I’m working with them to troubleshoot.

If I have to rebuild the heads (pray not) ill swap on C2 JWT exhaust cams. I really do NOT want to go through all that but will if thats what is needed to un F*%k those IPP heads.

So far I’m not super impressed with IPP. More on that after I sort all this head nonsense. If I require a rebuild that will be pretty bad.

Before I get too worked up though, I’ll do my due Diligence troubleshooting these heads with input from IPP. Wish me (and my bank account) luck...

Its not a good sign that brand new heads from IPP are not functioning properly. IPP built them from scratch (they would not accept my cores which seemed odd at the time)

I asked IPP to use the new JWT cams on the build and they assured me that they did only to admit later that they did not know about the C2 cams. At that point my motor was already build and installed so it was JUUUUUST days too late. That was a bit upsetting.

Stay Tuned (pun intended)

If you're going to swap the heads, you could look at going to 350Z/VQ35HR heads to delete VVEL, though I suspect there's a lot of work associated with it (and probably a new ECU).

I feel for you. I've been through this mess myself. No one wants to take the blame for their screw ups. :shakes head:

Bad rattle in my berk glass packs so I cut em open, gutted them welded em back up and reinstalled as “expansion chambers!! Lol

Exhaust rattle cured

That should fix it. :rofl2:

Surfdog , I assume they put together for you the Stage 2 longblock which is what I'm wanting to do. I'd be miffed as hell if they told me C2 cams and then did'nt have them. My question with me planning on getting the Stage 2 longblock is whether or not you're happy with the build of the motor. My goal is to get a minimum of 650 on pump gas and to do it I'm gonna need to be in the 16psi range with no concerns. I don't want to spend money on their longblock if you just got yours and you're not happy with it.

I’d be a bit careful using IPP. It might be that they are great, but my experience was disappointing. The heads are not running very well (either the lash is off or the lifters are bad or perhaps it’s something else that we have yet to diagnose)

I’ll let you know how it goes. For now to be safe I would stick with Z1 or look for recommendations here I. The forum of good engine builders.

BTW I don’t know much about FI, so cannot really help with recommendations there.

Thanks, FI or not if their build is sketchy pushing it will pop or bend something. Your top end not operating optimal after they put it together speaks to a QC problem somewhere because it should've been caught before it shipped and not after it was installed. I'll keep an eye on your progress, I have till February before I have to start writing checks.

Rebello Racing built my engine and I was pleased with the result. MA Motorsports is another option and I understand they are the exclusive distributor of the new JWT stage 2 exhaust cams.

I was thinking about adding an accusump to my setup as well. Thanks for posting yours. Which valve system/PSI did you end up going with?

My oil system runs high (near 100 psi). Due to Nismo oil pump. This will pretty mush just act as insurance if I cavitate the pump in high g turns.

Also it’s kinda cool to be able pre lube the motor on startup.

Surfdog's 09 journal
 

After an ocean of due diligence and troubleshooting it turns out the cam noise I have is due IPPs heads having a valve lash issue. Not cool on brand new heads.

The valve lash is pretty bad. I can’t run the motor this way.

I have troubleshot all I can and had my suspicions verified by my go to guy at a Nissan dealer nearby. (I know I know but the guy is good and also a friend)

Next step is to tear down the heads and reset up the lash with proper valve caps. It’s about 15 hours labor.

I’m not too happy with IPP.

On the plus side I can now retrofit in my JWT c2 cams.

About IPP

I have heard good things about the shop, and this story is still not over. I”m hoping IPP will make this right. I’ll let you all know how it shakes out. I hope to hear back soon about what their idea for the next step in getting me up and running is. Pulling the heads and shipping them back is probably not a viable option just due to labor costs. I will probably have to have the lash redone locally.

I understand stuff happens, and I think they are good guys down there. It will be interesting to see how well they stand behind there work. Like I said I’m reserving judgment. They may yet come through and make this right.

It has been quite a voyage so far trying to put my blown Motor back together.

Hope that everything works out for you Sir :xmastup:

:happyholidays:

It will al be fine. Expensive but fine. I don’t mind spending a little money on the car, I prefer it when they guys I’m working with do a good job and stand by there work. I really hope IPP pulls through. I’d love to give them a good review on a tough situation
