Gtr Engine Rebuilt, But Seems Slower Help!

Hey all, Hoping for some input :

I just rebuilt my GTR motor after the oil pump failed and took my crank along with it. I replaced the oil pump (n1) the crank (33 gtr) the rings (n1) and bearings… I put a sump baffle in also… thank that’s about it.

Now the engine is still on running oil at the moment. I’m not sure if this would have an impact or not.

Now… I have A greddy boost gauge which is not hooked up properly electrically, but also I have a HKS EVC which is working just fine, the EVC is reading 6 pounds which is what I have always run at but the car just seems a bit slow. More to the point I drove my mates supra the other day which has ever had anything on the GTR but I’m SURE the supra is running faster than my car.

Now I know I shouldn’t be smashing the car while its running and I’m not, but when you DO put the foot down, it feels like its running on lower boost… runs dead smooth but just not fast. The boost is definitely coming on. Just not convinced its running as fast as it did.

The head was shimmed before putting back on , and the rings are new, so it shouldn’t be compression…

Any other ideas at all?

I am as far as \i know. I am running th car gently for the most part, putting load on it up hills but not too much and so on, but from my reading I know that you shouldn't be gentle on it always sometimes you need to give it a hard time.

also i am on the home straight only 150 k left to go on my 1000, but when i put the foot down there is boost but just not much power.

makes me sad.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
