Im not going to cut any corners when/if I rebuild, so it may take me a good while to save up enough money to get it running again.

Isn't PRS that retard Bobby from VSR's new shop? I wouldn't let that waterhead assemble a balsa wood glider for me, much less a motor.

Could have been a crappy tank of gas. Did you fill up anywhere unusual? Ive seen it before.

If you want a completed shipped block call the guys at Import Parts Pro. They are a vendor on here.

Sadly it always seems to happen when you go to show someone the potential of your car. I snapped an axle doing the same, which created another line item on my never ending 'to do' list. I saved for 4 years for my build, so maybe you can make the 5 year plan work.

Sorry to see this happen and best of luck in whichever route you choose from here!

Z1 has a short block on their website now, built for some boost.

Hmm... I didn't know that. Supposedly they have had good dealings with the Subaru crowds and their "closed deck" blocks. If they are having a 3rd party machine shop doing the block, would you trust that? They won't be building the bottom end for me.

IPP has always had awesome prices on their motors. I'm kind of skeptical about buying a built short block for some reason and may end up building it myself. Anyone heard any bad things about IPP motors?

Nope. I filled up where I usually do. I would love to run a conservative tune on E85, but it's not very easily obtained here in Memphis.

I wouldn't trust any place that would employ Bobby to do anything right. IPP has been solid from what I've read. That's the direction I'll go if/when I join this club.

IPP has been in the vq game for numerous years. Trust them.

Ugg, had something similar happen to me on another car. I was just showing out for myself though....LOL 12psi of boost and clack clack clack. Dropped a valve seat.

BGTV8 · 08-13-2015, 08:17 PM

That is a comprehensive enforckeration.

zguynate · 08-13-2015, 10:14 PM

Anyone know where some good info regarding the HR head swap is?

Megan370Z or Clark Steppler at JWT or Brian At Valkyrie AutoSports

HR head swap will require aftermarket ECU or piggy-back ECU as the Nissan 370Z ECU expects to be managing VVEL and HR head swap will delete VVEL.

I am involved in a major CANbus sniff exercise on a Z34 but it is at least 3 weeks away from any sort of conclusion with no guarantee of success just yet.

"If" this works out as expected, there will be an aftermarket ECU option to run a VQ37HR in a Z34 chassis but there will also be some constraints ..... like cruise control will not be a feature, not sure about ESC/VDC and some other similar features.

When I have something definite to post, it will appear in my race engine thread (Search for "VQ40HRGA").

Just because you fill up there regularly doesn't mean that the current delivery wasn't mixed up or just crap. I had this issue a few months back. Filled up at my regular spot, got about 3 miles or so and the car started back firing and sputtering under increased throttle and throwing codes left and right. Would pull over, scan, take note, delete, and repeat till I got home.

Once home I opened up the tank, drained just over 15 gallons out (now being used in the lawnmower and running fine lol), pulled the pump, inspected the screen and bowl (nothing out the normal), reinstalled, put in 2 gallons from a different station the opposite direction of my house and car has been fine ever since.

Still have about 8 gallons left, would love to send it somewhere for some form of test to see wtf is wrong with it.

But, I was bone dry upon filling up, literally about 3-5 miles and the car started to freak out. Never filled up there again.

And out of curiousity, how did the tq get so close to whp? Most I have seen are at least 100 point difference between the two?
