Recommended Posts

You guys make me feel better about it. I was kinda down because it wasn't in the 800's. Thanks!

 

... this isn't a supra ...Though the first couple passes sounds like it is LOL

 

 

"whats the same about a 300whp supra and a 1000whp supra? They both run in the 11's" ;)

Really jon? So what is the dry sump motor going in? Awesome either way. I'm still hoping to get up there in august.

 

I will be putting the dry sump motor in my z this time around. But I have no doubt that I will end up blowing it up AGAIN. For this reason, this is the last time I am messing with the VG30E engine. Then its on to the stroked out boosted LQ4.

I raced in a local event on saturday called No Bull. I was hoping to do some license passes but still need a engine diaper first. I ended up runing in a 10.2 index class. I turned to boost down to 14~15psi and thought that was enough to hit 10.2's. I got one test pass and it ran 10.1 @ 140 but was spinning a bit. I lower the tire pressure for the first round and lined up against Nitrous SBC Vega. I didn't realize were on a pro tree. Opps. I tried to chase him down and broke out with a 9.99 @ 141. I need more seat time If I want to bracket race. I did one more run at 20 psi and ran 9.52 @145 with a 1.5 60ft. I pretty happy getting the car more dialed in. I beat my best et with 4 less psi.

I took the z out one last time before my winter project starts. Here are some photos taken at a local meet. The neon in some of the picture is one that I tuned and helped build. It has run a best of 10.25 @ 145mph so far. My winter project consists of shaving/cleaning up the engine bay and repainting it. I also plan on adding a bigger cam while the motor is out. Right now I'm thinking speedinc's tu2 cam. If funds allow I would like to change over to a air to water intercooler too. I'll keep you guys posted.

SOOOOOOOOOO glad you cut the hood all the way out.

 

I wasn't going to say anything before, but it looked haggard, even though you did a nice job with the cutout. :lol:

 

Were your IAT's really high, or why are you looking to go to an ATW IC? Don't want meth injection?

My Iat's were around 190 at the end of the track. I have considered Meth injection as well as giggle gas. Nothing is ruled out yet. I was hoping by doing a A2W I could run a inlet pipe to the turbo from the front grill area. I would have to put the radiator at more of an angle to do it though.

I started my winter projects. I pulled the motor and discovered there was some damage the the zo6 cam and one of the lifters. The #3 rod bearing was not looking good either. I decide that I want to rebuild up the motor with gen IV top end (ls3 heads) this next time but its not in the budget just yet. So for now I picked up a 5.3 LM7 to play with while I gather parts for the 6.0L. I started shaving the engine bay to get it ready for a new coat of paint before the motor goes in. I also got a swing out bar kit for christmas. So I got that installed. Should be easier to get in and out of now. I got a new 30psi boost gauge and msa headlight covers that will be going in soon.

Continuing shaving the engine bay. These shots are of the fire wall.

 

I wanted to move the engine harness behind the intake manifold to make it less obvious.

I got a nice grommet of a honda harness to fit.

I cut out some plugs and got them welded in.

Where the wiper motor plug cam threw. I don't have wipers though. So I pulled the motor and sealed up the top.

I will be down to 2 holes passing threw the fire wall now.

I still have some more holes to fill on the driver side.

Was it the lifter guide that allowed the lifter to turn and **** up the cam? I have a 6.0 cam as part of my mail box that has MASSIVE grooves worn into the lobes from the guide plates wearing out.

 

 

Don't get upset when you are able to push that stock 5.3 just as hard as the built 6.0. LOL

I still haven't pulled the heads off the 6.0L But I expect the guide to be broken. The roller part of the lifter is smooth in the center but scalloped on the edge on both sides. So it must have been rotating abit. I would love for the 5.3 to out do the 6.0L. It would be awesome and depressing at the same time. haha.

 

Another update:

Finishing up the engine bay. Here are some shots of the bay in primer. At this point I had a week to get the motor in and interior back in for a event I wanted the car at.

Fast forward a bit to some finished shots. It now has the stock 5.3 LM7 motor in it. I was on a mad dash to get everything transferred over to make it to another dyno day I was hosting.

Here are the headlight covers installed.

Here are a few pictures from the 5th Annual SQC Tuning/Motiva DynoDay/BBQ/Show-N-Shine. (Feb 2012)

I also Finally got a matching 30psi boost gauge in the dash.

I went back and forth trying to choose a cam. I was on the fence between the Speed Inc tu2 and the Comp XR281HR. I finally picked the later.

As I was doing the install, the lifters would not stay in the trays so I was using a magnet to lift them up while I slid a dowel in to retain them. I got to the last 3 lifters when the magnet broke off inside the motor. I did what I had to do and pulled that head off and got everything back together the way it should be.

Also on this round of upgrades is a new windshield and I got new Tokico blues installed up front. The old shocks were a little blown.

Lastly for this update got some logo’s donated for the car.

The goal for latest sprint to get the car ready was a local Import vs Domestic race named All Out Call Out. I had taken the car to work to make sure all was good but had no time to really dial in the tune on the smaller motor. I got two runs on the new setup in the test passes before the real race to tune it. On the first run I had the boost controller off and with 4psi it ran a 12.1 @ 115 with a 1.9 60 ft. Run 2 with the boost controller set the same as last year the new setup hit 18psi (down 6psi) and ran 10.3 @ 144mph (only down 3mph from last year) but still a weak 1.8 60 ft. It is not building boost on the line like it use too. Next up was the first round of eliminations and I’m facing Scott in the Vega that I ran in No Bull last year. I had adjusted the Ams1000 to push some more pressure into the top port of the wastegate and added some timing. He left the line with a much better reaction time but I was playing chase. Still no real boost on the launch but I came on much quicker and harder. I lost both my tach and shiftlight but still shifted flawlessly. Unfortunately the car didn’t stick with the increased boost and I found myself in the middle of a wild ride trying to keep the car off the wall. I succeeded in saving the car but lost the round with a 12.3 @ 110 mph.

A quick update. I know its been awhile. Sorry guys. I finally killed the stock 5.3L It wasn't even something cool. I was cruising to a car show doing 30mph when something that sounded like a tire blow out let go in the motor. No visible external damage or fluids but something is flopping around in there. I'm thinking maybe a wrist pin or rod let go. Since its winter time its time to start the next chapter in this saga. I finally got the 6.0 over to the machine shop.  I have sold off the borg warner S480 and have order twins 61mm's. Once the parts start showing up I will get pictures up.

That is the plan Dans toy.
 
I have gotten most of the parts I need for the new turbo kit. I'm finishing up a build for someone this weekend and then hope to start on my datsun again.
Here are the turbo's I'm going to run. They are precision MFS 6152e with t4 .58ar housings. I ran the t3 version on my integra back in the day and loved it. I'm speculating that I will have a power band from 3500 to 6800 although when I called precision they thought I would have full boost at or below 3k. We will see.

Here is what I'm hoping it will look like:

You should try building something that doesn't have parts sticking out of the hood!

 

LOL

 

Just messing. I look forward to seeing this happen. I'll just live vicariously through you until I buy a house and can hear that whistle under my own hood!
