I know I've been missing in action for quite a while, and it is mostly due to commitment to work and the extensive travelling required.

My inbox has been flooded with inquiries about the cars and parts etc, and I'm sorry that I wasn't able to reply in time.

The car is very much alive and kicking, spitting out flames at the exhaust on 3rd gear when I pedal it on the highway.

The boost setting of 1.6 bar has proven more than adequate for daily driving for now, and while I have no complaints on the power delivery but now I am starting to get used to it.

So this means either I have to learn to be contented with what I have, or plan for more upgrades.

In-Car Video

This was a pathetic attempt from us to produce an in-car video.

Boy, did we fail :-)

Nevertheless, hope you enjoy it.

World's First 500 WHP 1NZFE

Yesterday was a historical day for myself and GT Auto, after running in the engine I had the car sent back for a retune.

With a little help from avgas and a race map, we made 501 wheel horsepower.

And for my daily drive map, we managed to squeeze 454 wheel horsepower.

I am still pretty much out of words to describe how I feel right now.

So for now I'll just let the video and the dyno chart do the talking.

This is just the beginning.

Blue: 1.7 bar boost, pump gas, water/meth injection
Red: 2.2 bar boost, pump gas + avgas, no water/meth

Stage 2 Turbo - Base Tune

We got the engine fired up nicely, so we strapped it on the dyno to run it in and also to give it a base tune.

Currently the rev limit is set to 8,000 RPM at the moment.

With just pump gas, no water/methanol injection, no nitrous we made 404 wheel horsepower with 1.6 bar of boost on a very conservative tune.

So if we do a reverse calculation of a 15% power loss on transmission, the engine should be making around 475 horsepower at the crank.

The engine needs to run in a little more before we tune it again with a more aggressive map and with water/methanol injection.

I made a short video clip for your viewing pleasure, pardon the bad video quality as it was shot using a crappy camera.

GT Auto was kind enough to give the car a wash before tuning it

Stage 1 Turbo vs Stage 2 Turbo

By comparing chart with the Stage 1 Turbo kit, we could see that there isn't any difference in the power delivery at the low end so we don't really experience any turbo lag at all.

Now that there isn't any issue with lag, we might consider removing the nitrous kit.

Stage 2 Turbo - Work in Progress 2

The car is now back to GT Auto for more work to be done, however this should be the final work and we will be firing up the engine.

It also was nice to see Andrew from The N16 Files as he dropped by today to deliver more parts for his monster project.

Another mad fella in a quest to make over 400+ whp on his N16 Nissan Sentra :P

The intercooler pipings looks like bull horns to me from this angle

A Haltech electronic boost solenoid is added to regulate boost with the Turbosmart Comp-Gate 40

The BeatRush Direct Brake System is now fitted, we'll know very soon whether this thing works or not

Right after the down pipe we have 3 O2 bungs welded

right: stock O2 sensor which I have no idea why we are still keeping it
