Just In Case You Were Wondering


Can You Hit VTEC In Reverse?


Snow Plowing

Romping around in the snow on lowering springs was going to result in getting stuck.



A nice man in a van helped me get out so the fun could continue!

This is from my $10 video camera... Hope you like it. There is a Go-Pro coming in the future... Don't worry.

Merry Christmas

I didn't put a bow on my car this year, but I am sure you are sick of only seeing my legacy so here from the archives is my '72.

Stay safe and have a happy holiday from all of us at YNS Production and SeriousSubaru.

Looks Hot!


SVX with a Legacy GT front end. I was thinking of doing the opposite but I don't think it will be anywhere near as cool. K I'm gunna go split my block!

BO-OST Controller

So, when I was building my car, I was mostly rebuilding what was already there, just in another chassis. The previous owners of my engine had already tuned and equipped it. Part of that equipment was a better than stock boost controller. The controller that came on the car was a Blitz Dual SBC boost controller. Seen here:

For those who don't know how a turbo works, there is this thing called a wastegate. The wastegate functions as a turbo speed controller. As the pressure increases on the manifold side of the turbo, it will open up allowing the exhaust gas to bypass the hot side of the turbo, slowing down the turbo preventing over-boost, and damage to the turbo. Most stock, and manual boost controllers function linearly, meaning that as soon as there is positive pressure in the turbo system, it starts letting exhaust bypass the turbo, and once you are at full boost, the wastegate will be fully open.

Here is a basic diagram of a non-controlled turbo set up:
 

As hinted above, the big problem with this set up is that as soon as you have ANY boost, the waste gate opens allowing exhaust go by that could be used to help build more boost. This is where the EBC (Electronic Boost Controller) Comes in. The way my EBC, the Blitz, works is by breaking the line between the pressure side of the turbo and the wastegate with a solenoid that doesn’t let ANY pressure by until you are at (or very near) full boost 

See the diagram here:

So, to sum up the function of the EBC, it allows the turbo to spool faster, and also allows on the fly boost adjustment. The Blitz Dual SBC has 4 preset values that you can easily toggle between. I have 1 and 2 set up for low boost, 7 PSI for 1 and 9 PSI for setting 2 which I use for cold starts. 3 is my normal driving at about 14 PSI, and 4 is currently set a bit too high, so It works great on the roads, but on the highway allows too much boost, hitting my limiter set at 15 PSI, which turns the boost down temporarily.  This EBC also features a small tone warning so it will make a small beep if you hit boost above whatever you have the limiter set at. 

My only problem with this controller is that it is tuned, somehow, based on maximum available boost, so if your turbo is capable of making 28 PSI with the wastegate fully shut, and you want to run 14 PSI, instead of programming in 14 PSI, you tell the controller you want 50%. So if you don't know the maximum boost the turbo makes, you have to play games adjusting the percentage trying to find the boost you want. For me I was aiming for 14 PSI, which is about 62% of my maximum boost.

More Stuff for the EG

Got my box today from Diy Autotune--Your source for all things megasquirt. I also got started on what will be a full custom EG33 air intake out of PVC, we will see how all the angles work out under the hood.

So Excited!

I gots me a 120k SVX motor for my Legacy. Oh you know this is going to be good!


Dual throttle bodies promise more air to this sweet engine.




 Pulled my stand alone out of retirement!

Cars I Want Pt. 2

Last month I posted about the awesomeness of old school Supra's this month my mind has totally been on the SVX.


I've been looking at them for doing a EG33 swap into my underpowered Legacy. However the more I work with it I remember how badly I just want to cruise around in a bad-ass SVX!

The Next Steps

Alright, so everyone knows my plans for the lights on the roof rack...

Well I finally got bored enough to start working on it. I have 1 of the 2 sets of light mounted to the load bars.














So tomorrow will be the 2nd set of lights and mounting to the car.

After that comes wiring...

Stay posted for more.

I Guess We Can Handle It

Nothing long underwear, wool socks, and a cocktail won't fix


Nothing cutting, welding, recutting, rewelding and another cocktail won't fix

New England Auto Show Pt.3

Here are some more noteworthy items from last weeks show.

Nii's Maintenance Update

There are those weeks, the ones where you know you have a few little things you need to do to the car, or maybe a big one, but you convince yourself you're not in the mood (maybe next week, right?).  The things accumulate until the inevitable Productive Days arise, seemingly at random, and with surprising energy.

Productive Day 1:

  • Changed my oil (full synthetic)
  • Modified my custom undertray (added a lip at the trailing edge so airflow breaks cleanly)
  • Cut the heat-shields off my exhaust (stock crap rattling around with the insulation inside disintegrated)

Productive Day 2:
  • Bought and replaced my steering u-joint
  • Siphoned out some oil (a little overfull)
  • Welded a newly broken exhaust bracket
  • Replaced a hose clamp to the heater core
  • Painted the notched ends of my Cusco lower control arm brace (needed modification to fit a Legacy)
  • Drove to work with a crooked steering wheel 
  • Got home from work and readjusted the steering u-joint so my wheel was centered
  • Changed the rear differential fluid (getting those damn plugs out, what a pain! Fluid was black. O_O)
  • Tapped the holes for the Cusco brace and installed it

Not Productive Day 3:
  • Overpaid for 6 year old snow tires, because I am a certifiable moron/nice guy

New steering u-joint. After I installed it my steering wheel was cocked to the right, haha. It took several attempts to fix that because I turned it the wrong way one of the times.

Cusco rear lower control arm brace. I had to be notched to fit the Legacy subframe, so I painted the cut parts to prevent rust. Yes, a genuine Cusco part that's merely steel...

Installed. I changed the rear differential fluid before I installed it since the fill plug can't be accessed with it installed.

You can see the edges of the original holes on the right. The subframe is so rusty that I think this brace will actually help. The holes for it are threaded from the factory, but I had to run a tap through them for the bolts to fit.

As for what's next, I'm leaning toward engine response. I recently realized that a lightweight pulley frees up almost half as much as a lightweight flywheel, which is pretty significant. I'm still considering a MSD coil pack, and might install a gutted muffler, which we did on Squarebush's car. It's not very loud and works well; modest power gains about 4,000 RPM.
