Rebuilt our current 1600 sp a few years ago although it has a few upgrades (34 icts, leccy ign) it never seems to move like I expected. So I have a good 1600 engine from our late bay that I want to upgrade, without machine work and using 34icts what cam for just doing 0-50mph is recommended, will I need to go HD springs. Was thinking of using our mahle 1600 b & ps as dont want thin wall with the chance of warping (wet/damp weather). Could I take it somewhere to alter compression ratio maybe.
Plan is upgrade to ecu wasted spark set up for ignition only, cb throttle linkage reuse, oem twin webers, C25 cam and better flowing exhaust and sell 1600sp engine turnkey.
Dont want to go down of route of machining thats why originally I opted for s/p for durability but may replace oem exhaust look which we prefer to a vintage speed oem appearance.

My engine skills are very basic so please be nice !!

H.P is in the Heads, go dual ports , add a pair of 40 IDF's a nice header and you'll be Happy Wink I would not waste my time with S.P heads and single throat carbs!

If it's a '71/'72 Bus engine it will already have dual ports heads. That is worth 3 HP in stock form. VW got 66 HP out of dual single carbs on the type 3 engine. The crank trigger ignition will net you some drivability and maybe a couple mpg but little in the power department over stock ignition. The cam change without any change to stock heads might be worth 3 HP but expect to loose a bit on the low end. Maybe a HP or two with the exhaust. I'm thinking 68 to 70 HP? Your current one I would guess is giving you 60 HP now.

I guess what I am getting at is your total power gain is going to be very modest. You need to decide if it is worth the $$ spent.

Oh! And as for the no machining thing... good luck with that! I have rebuilt a number of these engines over the years and have yet to find a used type 1 engine that did not need an align bore.

Why are you intimidated by machine work?

Building a nice 1776 can get you 80+ HP and be a great pleasure to drive.

Not in the UK, Type-4 was an option. we could still get 1600's right to the end of production and the vast majority of UK buses were 1600 powered.

Well, forgive me - I didn't know where "Cambs" is.

By the way - I've run 1835cc DP engine since 1976, and love it.

Read all you can about different builds here on the Samba and then research parts availability and cost. It won't take long to get a grip on the possibilities.

You are forgiven. lol
You lucky Americans seem to have got the best of the best as standard, so many deluxe buses, type-4 engines etc. All these things were options here and the import tax was so great in the 70's that most people went for a very basic model instead. Many of our campers were stock panel vans converted from new in the UK purely because the import tax was far less on commercial vehicles. Horrible things TBH but £ rules.
