I have 10k on mine so far. All I've had to do is oil, plugs, and a couple coils.

I haven't been in here in forever...My 550hp+ twin turbo has been with ME since '07..I have put roughly 25,000 miles on it..I have raced the www.bborr.com 7 times and had several track days...I rebuilt the turbos and flow matched the injectors about 9 months ago...pulled the motor, did the pathfinder mod and a bunch of wiring clean up and wrap...
just replaced the wideband o2..it went bad and was giving erroneous readings...I am registered to run the Big Bend race in April..car runs like a scalded *** ape!

I have been running the same Built motor since 2004. Charles At CJM built the motor. Over 40K miles on it now(Not sure on exact numbers). Power has been anywhere between 550-650+whp. Last tune was By Hal 636 Dynojet last year.

This year i am planning on pushing the motor pretty hard. Using Twin GTX3076 turbos. Using a set of custom CJM turbo manifolds. Upgraded intake and ID1300's. Shooting For 800whp maybe a little more if everything is going smooth.

I think most VQ failures are from improper tuning. These cars are also not the easiest to work on and a lot of simple mistake can be easily made. These motors make so much torque for there size and spool pretty quick which makes them so hard to tune.

I personally think the VQ's are VERY underestimated. Not many stock block motors can make it over 900whp. No one really even know's where the blocks limitations are. Watching all these VR's make over 1500whp on the stock sleeves makes me think.

Stock block 900whp VQ and over 1500whp stock sleeves? Are you high?

I think he meant sleeves for both.

unless he is from relentless auto

He means VR stock sleeves


IE Vr38dett.


But they aren't at all comparable, if anything the vq should be much weaker; open deck vs semi closed/closed.


I've heard reputable shops claim that vq's push water at like 700hp, I've heard that certain parts wont hold four digit power, I've heard that vq's can't be reliable, I've heard that you need to replace your hG all the time.


Don't go by everything that you read. Do your own research on how things work and go by that.

I have been running a vq in a track car, the engine is making around 760hp the engine never uses water, running stock sleeves.

Used to have issues with head gaskets, changed to power enterprise gaskets that are made in Japan had no more issues since.

Even the VR engine won't make 900whp on stock block.

A shop that sponsor's this forum just made well over 1000whp on a stock sleeved Vq. Not going to say who or when they did it because i am sure they will be making a new thread about it when its time.

There are Several Vr's making over 1200whp on stock sleeves. I know of at least one VR that makes just over 1500whp on stock sleeves. I am sure there are more out there. I have a couple friends that work at AMS (I am not a fan but they tune alot of GTR's). They have yet to break a stock sleeved motor that i was told about. They have had a couple sleeved motors fail.

Sounds like he is saying stock block as in specifically the block/sleeves. not the typical use of stock block which is causing some confusion.

they are several threads and post about the sleeve strength and no need to do drop ins for under 1000whp. it's nothing new.

Yeah, I just got that.

Ya.. Sorry for the confusion. I was referring too the block its self.
