    Alright, I figured I would start my own thread instead of using the parkway projects thread.  I purchased this car a year ago in pieces and have been working on it in my spare time.  It is a numbers matching, pan, engine, trans, body and I believe front end car.  It has all of its original clips hood deck lid doors and one fender.  The rear fenders are correct heart fenders with one being NOS, the one left in primer with the factory part number on it.  I also had to source one early front fender as well.  This is an original East Coast car and I believe it to be a Hoffman car as well.  It was very rust free and has been off the road for decades.

    Since buying the car I have sourced all of the missing and zwitter only pieces for it.  I have also stripped back the red primer and white paint to find the original paint.  The car is mostly original paint and the darker green is what I put on,  it is just rattle can metal etch primer with clear over it.  I have finished all the rust repair and metal work, and sent the pan to KCW to have blasted and painted, along with a bunch of chassis parts.

    The trans got a full rebuild from Rancho, and the engine is a 36hp based 1558 stroker I built a while back, then sold the car I was going to put it in.  The brakes have all new hard and soft lines and Porsche A drums, backing plates and wheel cylinders,  with a rebuilt 19mm master cylinder.  I also rebuilt the original steering box.  All hardware was blasted and black oxide coated. All seals have been replaced, the car has been completely rewired and everything electrical is functioning. I also just mounted some new Firestone bias ply tires and tubes.

    Just finished going through the fuel system and was able to get the cam broken in as well.  Now I am in the middle of tuning the engine and jetting the carbs, I have a few other things to do to dial in the engine.  After getting everything assembled, I realize I am going to need to get a new interior.  What is left of the original is in such bad shape it just falls apart when you touch it.

    That looks so nice Josh. I hope we can get you to do a rally with us.

    I have some scraps of various original split seat covers if you want to try patching what you have. Yours, if you can use them.

    Thanks Franz!  Just need to get it all dialed in and I would like to do a rally with you guys.  I think my seats are too far gone. I dont think the fabric would hold a new stitch.  The Zwitter and 53 oval fabric is also a different pattern from any of the other years as well.  I need to see how much Doug would stitch up some seat covers for me if I got him the fabric.

    Great build!  What are the specs on the Okrasa to get to 1558?  Would love to see video of it running if you have any.

    Pete, it is a 83×72. Lots of work to make that happen. I will try and get some running video when I get it dialed in.

    Thanks.  I was trying to get to 1558 using the 74mm Porsche crank and couldn’t so I was guessing you had some custom stuff going on.  I’ve got a 1397 okrasa in the works (80 x 69.5) and was curious about your setup to get that displacement.  I bet you had a fair amount of machine work to get that to play well together.

    I sent my stock crank to Jose at DPR and cut and welded it to 72.  He also 8 doweled it along with my flywheel.  The cylinders had to be rotated 90 degrees and I had to refile the stud pattern to fit the 36hp stud pattern.  I then had to clearance the fins to allow the fit and also clearance some of the fins to allow the cylinder tin to fit as well.

    I built it a couple of years back, if I remember correctly I chose the 72 because it fit with very little or no internal clearance issues.  I believe I had to take a very minimal amount of the  piston skirts and then have them re balanced.  Cylinder shims were the worst part.  I had have them custom machined to obtain my deck height.  As I remember the 74mm crank needed quite a bit of clearance issues including taking some material off of the cam.  Also with the 74 Porsche crank you have the issue of which rods to run, and the main bearing issues since porsche used different size mains than VW.

    I built this engine before AA reissued the 80mm pistons.  They were very hard to find and expensive then.  The 80 x 69.5 is a pretty sweet set up!  Very little extra work to install, minimal extra $$$ to purchase, and readily available.  I definitely have way more labor and time in mine for minimal horsepower gain.  I was just very interested in learning how to build something new at the time.

    What carbs and exhaust are you thinking about running.  WW sells this one now

    Very cool, but a bit overkill, expensive and probably loud.  It wasn’t available during my build.  I chose the vintage speed single tip.  Looks great, sounds good and was priced pretty fairly.  Also it is adjustable to fit a stroked engine which eased my pain a bit.

    Wow…that’s an impressive amount of work.  Should be a killer performing motor.  I love the look of your car…definitely has that Vintage Speed vibe.

    For my motor Joe Ruiz is in the process of building the long block, and KCW will build it out to turn key.  It has the Wolfsburg West crank and performance cam and the AA 80 pistons. Head seats are being replaced to accommodate larger valves, and I’ve asked for some mild porting/polishing.  Speedwell intakes, carbs undecided.  Franz has some Solex P11 40’s he’s offered up, but we’ll have to talk on that…I’ve heard they’re expensive to rebuild, rebush if needed and something about converting to solid shaft from split.    We haven’t talked specifics on them yet so I’m not sure if they’re ready to rock or in need of an overhaul.  40 idf’s/dells are an option….I want a reliable driver foremost over authentic vintage.  He also has a Porsche shroud/rear mounted linkage which I’d really like to take him up on.  I have a Vintage Speed abarth style exhaust on order which will hopefully show at KCW in the next week or two.

    Nice, sounds like it will be pretty fun.  I think you can mount 36 Dells to those Speedwell intakes too.  I heard Franz really likes them, and loves to work on them.  Hahahaha.  What about the 32 Solex PBIC units?  I will let you know how the Zeniths perform.  Everything I have read about them gives a pretty good review: production runs were long so many available units, parts are pretty much available and not too overly priced, and they sound to be pretty strong running carb.  There are also many quality re builders out there if you need a set rebuilt.   Also, manifolds and aftermarket air cleaners are available for them as well.  They seamed like a good fit for my engine displacement and driving needs.  Also just a heads up and my two cents, if you want reliable driver and practicability, go with the stuff that has been proven, has the most reliable info out and is very accessible.  With that said I would try and stick with front mounted linkage as VW intended.  Less modifications and fab work, more readily available, more practical and easier to access, especially road side, and probably less expensive.

    them guys there are typing on computers… 😉   Like me.. 😀

     

    I love these bad ass 36HP motors..  I’ve thought about giving a build a try.. but I want to go turbo 36hp… 😳

    I have the Wolfburg West Solex 32’s, and Ruiz is going to rebush them and change the jets and venturis.  But with the bigger bore/larger valves/raised compression I really think two barrel carbs will perform better, especially on the bottom end.  I’m thinking I’m going to sell off the balance of the WW dual port kit since I’m only using the heads.  As for linkages I have both the original style and the CSP that WW offers, so we have options should the Porsche shroud be too cumbersome.  I’m liking these air filters for dual carbs: https://www.thesamba.com/vw/classifieds/detail.php?id=881918

    them guys there are typing on computers… ? Like me.. ? I love these bad ass 36HP motors.. I’ve thought about giving a build a try.. but I want to go turbo 36hp… ?

    They’re not for everyone; I know a 1914 would put out more power for less cost, but I like building off of a base correct for the model year and really dig the vintage speed stuff.
