throttle valve reverser dimensions for EJ2x engines

[mwebber]

If your not going with a turbo make your own using the stock parts. That's what I installed on the 64 bus.

Could you pass me a copy of that picture at full res? That looks like the UUEL! (Ultra-Un-Equal Length!) header. I'm specifically looking to avoid the 'boxer rasp' that every other rice-rocket seems to be trying to cultivate with off-the-shelf UEL headers. I'd prefer the Bus to cruise by and no one think anything more of the exhaust note than they would of a Honda Odyssey. Shhhh.

Nicely squashed out oil pan there. Did you fab that or was that a purchase?

M,
Are you asking me or Joel? Mine does not sound like subaru and I have since changed out for a small Thrush muffler. On my Beetle I made the muffler to look like a stock VW unit and it sounds like a beefed up VW motor.

Well what the hell...as long as I'm at it I'll ask both of you!

The exhaust issue is one I'm tempted to try my hand at, but goes against the grain of 'what is commercially available' then to 'what is available from the boutique (custom) shops' and then finally 'what spec can we publish for having a shop Fab this according to instruction.'

My concerns about the oil pan are not quite as extreme as the nutty off-roaders. Unlandened weight, I want that oil pan at least 200mm (7.8 inches) off of the ground. Because that's the Unladened ground clearance of a stock Bus. (Trivia: What's the lowest part? If you're running over a dingo, he'd better be shorter than 200mm if he wants to keep his skull intact: The lower front torsion bar is the lowest part on the vehicle. That's going to contact anything I'm rolling OVER first.)

I take the stock unit chop it up and reassemble to fit my needs. It actually sits higher than the stock VW exh I make it fit as high as I can but allow room for movement. The oil pans I have done are shortened 2 3/4" and I extend them to the front so I keep the proper oil capacity. And it sits higher that the exh and I haven't hit anything yet. I don't use 1/4 plate since I am not building an off road vehicle.

The sump on mine is one of Custom Veedubs.
They are the mob in Brisbane that were making the throttle reversers.
It's not a cheap option, they are $600au but was worth it to me.

It was one of the only parts of my conversion I farmed out so I didn't mind paying that as its 85mm/3.75" short than stock but holds more oil than stock too and is clearanced for stock subi engine mounts if I ever went a subarugears trans.

Even at 85mm shorter it still hangs about 1" lower than the sump of VW engine but the lowest part of my conversion is my header where it runs under the transmission anyway but even that is 6" clearance on a lowered but, the lower shock mounts hang down further.





With the muffler, if you get a fairly quiet one and set up the header reasonably close to equal length you will get it sounding like a VW engine just with no valve train and fan noise.

I personally love the boxer rumble, you can't have a subi engine without the subi sound.
THe looks I get when people spin around expecting to see a WRX and see an innocent VW are priceless even after all these years.

But I can understand some people are doing the conversions for a modern, reliable QUIET engine and wouldnt want the noise or attention.
I wouldnt go an exactly equal length system as it really will sound like a Honda but just slight variations in length will keep that VW noise.
It's when you get huge variations in length that you really get that choppy thump thump thump note..

Steve, I just noticed your header turned out pretty much exactly the same as mine:




I got the EJ20 Impreza header as the stock EJ22 Legacy one on the right was just to messy to do anything with.

[Prtexx]

Yes they look very similar I have it tucked up nice and high and so far no problems. I also used the stock flanges and the y portion. The VW look a like muffler is very throaty and gets attention sounds like a strong VW engine but without the squeak. BTW you did a good job on yours it looks clean and well put together.

[Buggin_74]

Thanks Steve,
Jake Raby worked out the secret for header length and collector order to get a VW note out of them.
A friend of mine put an EJ22 in his 63 single cab and used a sidewinder muffler, it sounded nice.
Most people were shocked when the engine lid was opened and there wasnt a VW engine in there

[webwalker]

So was your friend a customer of JR's or did he just hear about the secret sauce?

M

[Buggin_74]

Absolutely no connection there, he just made his own header up to fit with the available space and mate to a VW sidewinder muffler.
Just sounds like a hot VW motor with IDAs

[mwebber]

Yeah, I'm looking for the quiet ride, not the 'hang on Sheila, here I Come!'
