I'll bet you've never seen this one...

[silverbulletAWD]

Hey guys, I used to post on here years ago and I kind of got off track with a business I started. I haven't touched my car for like three years and I never totally finished it but I thought some people might like to see what I did to it...

I put more pics up with some description on this site too:

Very impressive!!! Does the stock hood still fit?

 

[talonalex92]

How did you get pics of my car?!?! Hahah kidding, looks awesome dude!

 

[Phil1320]

Definitely one of the top five DSM engine bays I've ever seen! I'd like to see that thing done and run......keep us updated and good luck finishing your project.

Jeez, that is really nice!

This may be obvious to everyone else, but what are these fittings/lines for? Vent? They look too heavy for that...

That roof scoop makes me . It is very clean, though. Those aren't the OEM engine mounts, are they?


BTW, for all you noobs out there, this is one way to get an Evo VIII/IX (or IV through VII, for that matter) into your DSM. Have fun.

Crankcase vents. You can see someone else did a similar configuration here.

They are -6AN or -8AN lines ( it allows for all the crank vapors to be removed even while boosting( unlike when using a PCV)). I see race applications using them mostly. Notice that he blocked the stock location vents.

Wow Very impressive.. Keep up the good work.

?????? You might want to look at those pictures again.

I believe he is talking about the Evo 4+ turbos, which have the compressor housing on the opposite side compared to DSMs, just like the turbo in the picture.

No, you are wrong. The Positive Crankcase Ventilation valve will let blowby gases through, at idle or WOT. Boosting or not boosting, its still working. It allows fresh air to be brought in the crankcase and allows for the blowby gases to be drawn in to the intake manifold to be essentially burned up...

The only reason why they replace the PCV system with the open setup is because the PCV system can only do so much, and it can only go so far. The air/blowby pressure get so great, that they will go through the intake manifold and your air intake and cause major problems, and to avoid that, they reroute it like some of the setups you see here. That is usually why its routed to the intake, for fresh clean air to enter the crankcase and so it can allow the blowby gases to escape through the intake manifold. Its supossed to be a closed loop system, until you do this to reroute it. Its not wrong, if you do it right, but most people don't. And these were one of the first emissions devices put in place by the EPA/SAE. The government set the regulations, and we all had to follow it.

The plenum design is horrible.

 

[AshTsi]

Man, that is Super impressive!!! Congrats on the nice work. the only problem i have is that you said you havn't touched your car in about 3 years.... thats a crime against nature! how could you not just sleep with that thing! Sorry got a little off track there, beautiful car though! looks great!

 

[turbo90gsx]

So when is it becoming active again?

Agreed!!! WTF

I'm glad you guys like it. I know it's a shame to leave the thing sit. I need to rebuild the engine now before I can run it again. I never did get this setup to the track either... I started a type of fabrication business that has completely consumed my life for a while now. I think maybe this winter I might have a chance to get back at this thing.

I'm building a custom head that I welded the ports shut on right now. The ports are re-cut to a design that I came up with after about two years of serious airflow research. I have a design for some custom pistons that I will need made and I believe I have about all of the other major stuff here now... I also have a design for a complete K-member and rear subframe replacement that will also replace all of the suspension arms and relocate all of the pivot points. I'm finally getting caught up at the shop lately so mabye this winter...

Oh, and whoever said the plenum design was bad, I'd like to know why that is? Do you know something I don't? Or is it just different than what you've seen? Yes, I do know of a few things that could be different but the piece in these pictures was built as more of a study of the actual runner design.

You guys are right about the crankcase vents on the valve cover too. I wasn't using it quite the same as it was intended though. This was another one of my ridiculous ideas I never totally finished. I don't think I was the first to try this but I came up with a fitting to weld into the exhaust that could create a negative crankcase pressure with which I was hoping could actually help suck the pistons down on their down stroke. The problem was I was actually sucking some oil out of the engine in the process. I had to build a small surge tank to catch it and I already had an electric pump taking the return from the turbo so I used that to pump all of the oil back into the engine... Like I said, I never really has the time to totally validate the idea so who knows...

 

[matthewdesigns]

Thanks for the vent clarification, guys.

One of the names of the game is smooth transitioning. I don't consider an intake plenum that resembles a UPS box I get in the mail anywhere near ideal.

BTW, I'm still wondering if those are the OEM motor mounts.

Hm. I don't know if there's enough energy in the exhaust system to do much with this. But, I'm keen to hear about it.

Old news, V8 drag racers have been using exhaust scavenging to pull crankcase fumes for years. It does work (better than a regular PCV), but it's not wise on a street car as it only works when the exhaust is at high velocity (WOT). Vaccuum pumps are better if you're trying to actually create a significant pressure differential on your crankcase, or better yet a dry sump .

Agreed to an extent, but when volume conflicts with packaging one must make compromises. I will say the major change I would make with the next one would be to build large radius' on the back edges. That's about it. Like I said though, I was in the process of validating the runner design and not nearly as worried about the plenum, as should anyone.

The motor mounts are all stock. I just cut the front off the driver side mount and capped off the front.

I'm suprised no one asked where my alternator is yet

Your right on all counts. I had to redesign the fitting to get enough vacuum at low RPM's and that actually turned into more problems. I think that's why this idea was left alone by others a long time ago but I'm the type that just has to find out for myself.

 

[99gst_racer]

Car looks bad-ass, Andy. Hope to see it running at Martin next summer.

 

[tstkl]

im guessing the alternator was relocated to the rear axels to have better weight distribution, so the car can only be on when its moving or as long as the battery supplies it,....


but thats just going off the other crazy ass shit you've been doing,...

in all seriousness, it looks like your car is in some dire need of practicality,... that uicp, that turbo location,.... that CAR

as for the whole "this is an evo in a dsm"

the turbo is a dsm style, the motor is a dsm motor, someone better step up and give me some of the drugs they are on or prepare to get tally wacked.....
