 Posted: Wed May 12, 2021 1:38 pm Post subject: New Engine for daily driving, 71 squareback |
 |
|
I have a 1971 Squareback, with a rebuilt 1835cc engine, with a single EMPI two-barrel progressive carburetor. Recently, it has been jerking when getting up hills, I'm thinking it might be because it might have an acceleration pump gasket leak. Instead of fixing this I'm thinking about just replacing the engine. I've had it for about a year, but as I'm starting to drive it farther everyday and need it to be more dependable I'm thinking about getting a new engine of the same power or even a little more. In addition, I'm thinking about changing the shocks to make the ride a little smoother. Does anyone have any recommendations for an engine and smooth shocks? Any help would be greatly appreciated. Thanks.
Here's a link to what the car looks like. https://bringatrailer.com/listing/1971-volkswagen-type-3-squareback/ |

| I'm also wondering what the difference is between a performance turnkey engine and a longblock engine and which one would suit daily driving better. My budget is around $5000 for both the shocks and engine installed. Thank you! |

It might just need a tune-up. Are there other reasons you are leaning towards a new engine?

A big reason why I want to get a new engine is because of the carburetor, since it's just the single one it sticks out and has to have a box around it that takes up space in the back. I'd like to get a dual carb setup also. |

Yeah, really dislike that box too. Even worse is just not running an engine cover. 
But changing that doesn't require a new engine.
VW ran a dual carb setup before going to FI but those little carbs probably wouldn't feed an 1835 very well.
The challenge with a type-3 is getting dual carbs to fit under the engine cover. You really need a compact carb with short manifolds.

Softer shocks will not make it ride better, unless someone installed stiff higher-pressure gas shocks or helper spring/shocks.
The stock Type 3 is very smooth riding, with long suspension travel and progressive action.
However, broken or missing bushings can make it clunk and feel worse than it really is.
Replacing shocks with stock parts, a good alignment, and checking/replacing rear suspension bushings may make all the difference you need. |

Not a big fan of the center mount weber progressive carb. You loose all of the cargo space. Source out carbs for a type three. They are out there to find along with air cleaner. That is what I had to do.

the 1835 is a good size, just lose that progressive carb, it's the carb equivalent to a bucket with a hole in it. You are probably just running really rich with that thing.
Buy a set of duals, tune them, and you'll have a runner that should keep up to traffic no problem. Even a set of stock type 3 carbs, with larger bus venturies and new jetting would work better

Exactly. If not talk to someone at CB Performance about some dual carbs jetted for your engine size. Either some 34 ICTs, or dual 40mm throat carbs.
Also, since the front end is lowered, try and find some link pin oil shocks for a lowered bug. Those gas a just shocks are too stiff to use.
Keep in mind that the skinny tires aren't helping with the handling, which is why most of us run a 185-195-60 wide tire up front, and a 205-65 or 205-70 in the rear. Some of this is from years of driving our cars. Myself I learned that the stock width 165's were too narrow on a road trip, so I went with 195-60-15's when I needed to replace them. Then I changed the rears to 205-65-15's to keep the gearing correct. The big and little combo gives just enough rake to look good, but also handle good.
Something to keep in mind, is that you may want to check over everything chassis related, just in case the PO missed something suspension related (either end). These cars were designed to be serviced every 3K miles, and depending on the PO they might not have gotten that service.

Cool! Will definitely look into that! Thank you for the advice, would these type of carburetors be compatible with the engine without a lot of effort?
Thanks! |

They should be. Make sure whoever you talk to understands that you need the shortest manifolds available. This is to keep everything under the load floor. The big plus going to dual carbs, is that it gets rid of that box poking thru the floor. Most type 3s run better with dual carbs, and even get better fuel economy with them.Mark (W1K1) is running a similar sized engine as you are, but with dual 40's (twin throat carbs), and has been enjoying it as a daily driver. He did have to add an extra oil cooler, as he was concerned about his oil temps.

Cool, talked to a mechanic earlier today and I'm going forward with the dual 40's, does $1300 installed sound about right? |

That one I can't help you with, mainly because shop rates vary so much from state to state and region to region. Not to mention 870+ of that will be for the carbs themselves.

That doesn't sound unreasonable - with carbs, manifolds, linkage, fuel pump(?), etc. plus the time to install and tune them.
Also, be sure the ends of your fan housing are plugged. You're losing a lot of engine cooling air flow.

Agreed. There was an Invader from Arkansas in a white Notch at Carthage with a 2110 running dual Solex carbs (rejetted and larger bus venturies). His biggest problem was cracking the top of the stock air cleaner. I didn't get the jetting info, but maybe Brian did, as he was asking all sorts of questions.
My son is running Weber 34 ICTs on his type 4 powered 1700 with domed pistons. It runs very well with them. He ran those same carbs on his 1600 engine too.

^ i like that. the 1600 i threw together for mine has a counterweighted crank, engle 110 cam, china IDF 40's , and the compression is sitting at around 8.2 right now.. it will be 8.5 when i pull the engine down and re-do this winter as a backup motor. I've been very happy with the setup but because i can never leave anything alone.. the 2110 is building the parts list now.
