Performance intake and exhaust?

[Max Welton]

My fastback should be out of paint in mid January. While I'm waiting I'm thinking about engine options. Even more dangerous, I'm asking for ideas on thesamba.

God help me.

I currently have the 1776 I was running in my daily-driver squareback until 2016. It's fitted with an ISP OOT exhaust, stock heat-exchangers and I've adapted a stock FI intake from the old 68 squareback to use modern injectors. It's very smooth and a great cruiser but the stock intake and exhaust limit power to not much above stock. This engine is sorted and fresh and the default option for this car.

I also have a 2110 configured as a type-1 for my Karmann Ghia that is still just a long-block. It's all new but unfinished and not yet run. So now I'm thinking about pulling the 2110 out of the KG and using it in the fastback.

What I need is an intake and exhaust that would support 100-130 HP in the type-3.

The stock type-3 cooling system will be retained. No upright engine in a type-3 car for me.

The car will stay FI/megasquirt. I've put a lot of time into learning that system and very much like it. The intake must remain low-profile to fit under the engine cover.

For the exhaust I'm prepared to make my own type-3 heat exchangers if necessary. This car requires heat. What is available for a performance type-3 exhaust?

So ... ideas?

Vintage Speed. Thats it. Anything else is crude and or pushing back to stock.

Having a stock muffler on a performance motor is not bad. Just not as crisp.

If money was no object, CSP makes performance heat exchangers and a python muffler that will support some serious power. As for intake, I would look at buying some mandrel bends (Columbia River mandrel bending) and make my own runners and mate them to a newer style throttle body.

1.5 header and I build my own 2 inch turbo muffler set up. I think the muffler, flange and 90 pipe was 40 bucks all in, new.

I bought the VS stainless exhaust for my KG. It looks great but it seems quite heavy. Read a little about people having them crack at the welds. Might be worth trying to fab some additional support so all that weight isn't hanging from the heads.

The CSP Python looks nice in the ad ... heat exchangers too.

What did you use for the header?

does A1 do a type 3 sidewinder? that would be nice on a 2110cc
We have one on the wifes 2110cc on her 73 super

the Vintage speed sport muffler has been on my square for several years now, it's solid, but I don't think its heavy compared to the stock exhaust, maybe compared to an EMPI tin can exhaust, or the OTT but the quality difference is Big.

the 38mm J tubes from vintage speed are an easy fit inside the stock heat exchangers

vintage speed VS OTT

I have a CSP Python with a 1904 - it's expensive but, IMO, well worth it. The only thing I had to do was come up with a bracket to mount the oil filter/thermostat bracket. The exhaust pipe exits the right place on the rear apron and the pipe is the correct length so it doesn't heat up the rear bumper.

The VS exhaust didn't fit my car for some reason. I tried to fit two of them and neither one fit in the apron cutout and the exhaust pipe was just the right length to heat up my rear bumper (too short).

I think STF might be the ticket for runner diameter and plenum sizing. Or you could always go to some IDF throttle bodies.

[Max Welton]

No doubt. At least we got some exhaust options.

Hi, Max; good to see you here again and still active with your VWs. Thinking out loud for heater boxes: CB Performance now sells a Type 1 performance 1 5/8" HB with full aluminum internal heat fins. https://www.cbperformance.com/product-p/3682.htm You could do a reality check by placing an old Type 1 HB next to a Type 3 HB so that you could see the differences in length and design. Thought is, if the outer metal SHELL together with the heat flaps at the forward end could be removed from both HB by uncrimping the joints and transferred over, then you could use a Type 3 HB shell on the CB Type 1 hi-po HB. Might need to extend the rear outlet pipe somewhat, but you are good with the welder.
