where 87 came from is back in 1970 what they did is instead of giving you new p/cs they would use a old school piston expander and then there was it looks like a drill press machine that was a cyl bore hone and then stick some .010 rings on it . then they had green end wrist pins that were over sized and hone the bushing in the rod and the piston to match , they charged 8 bucks a piece but when you could get new VW brand p/cs for 10 bucks a piece WHY a 87 is a 85.5 .010 over sized . now they make them new but back in the day they were used .
I have 2 - AS 21 cases. Sitting on my bottom shelf in the back. Saving for rainy day - ha ha !!! Both have never been machined. All stock - might have to sell to buy groceries if things keep going up !!!! Excellent video as always - thanks for the info.
Thank You for sharing with the VW community. The thin wall 87 mm and 92 mm cylinders are a bit risky = hot running... A 1904 is a good choice due to very little case clearance work. The nice cylinder heads available today save a lot of money. Having custom head porting is money. One quick point for performance is with a higher lift/duration cam you can bump up compression. For my own engine I will run 9 to 1 in a bug with a 110 cam. In a bus, 8.5 to 1 (realizing a bus engine has a shorter lifespan 😊
I used to be a vw mechanic in early 2000’s, that 110 cam is old school mentality, I’ll try and find my old cam profiles but we ran special grind web cams, there’s a lot goes into making power but yes a good cam is where to start. I found using a flapper paper, made my own tool with a rough grit paper and de burring heads urself is way to go saving money.
Well said Mike. I am Looking at building a 1904 just like in one of your videos. W110 cam good to use or do you recommend something else? I am thinking about using a Holey Sniper too.
Ok Mike like your videos, building a 1904 new case 74 crank scat 35 cam looking to be around 8.5 comp ratio oh yeah rods 5.325 rods what cc heads should go well for this application thank you for your knowledge
Thank you so much, always on, truthful and helpful. You've really helped me. I'm rebuilding an engine now based on your advise,can a I use my stock/currently in operation lifters and or I'll need to buy the kit of Engle 100? Thanks in advance. Respectfully yours.
@@Mikefngarage Thank you sir,sorry for the dumb question;what are are reground lifters?? I bought this cam: Camshaft Lift Duration @.050 Lobe Center Rocker Ratio 400" 257º 108º and 1:1.performance rockers. I kindly ask do I need buy set of performance lifters? Thanks in advance. Respectfully yours.
@@felixmwanza.1912 stock German lifters sent to a machine shop to be resurfaced. (reground) Must be German or it wont work. never thow the old ones away even if your getting new ones. Cores are becoming extinct.
@@Mikefngarage Thank you so much for taking time to educate me,I appreciate it very much. 2 last qns and won't bother you farther; 1.if I'm to buy new ones,what is the size 28,30 or 31 mm 2. my old ones how much are they to be re-ground please? Once again many thanks and beg your pardon for too many questions. Blessings 🙏
Mike, what are the reasons for not building a single relief case if you are not building a performance motor? I have seen people build them to 1904 or even bigger
Thank you you all way give your viewer different options I have Mexican cases are Brazilian heads good quality for building a stronger 1600 you don't recommend a 1641 for a bus what do you recommend ? Asking for a friend !
74 stroke. if your keeping a stock case and have access to head machine work only 1800. if you have only stock heads you can do 74 stroke 85.5 But you will need to trim the piston skirts on either one. Not hard to do.
Hi Mike, a dumb question, perhaps. I have a 1302 with dual port 1300cc (40hp) and the plan is to go up a bit with 1600 (or 1641) kit combined with engle 100 or 110. If i understand correctly, performance cams have better material, build quality and some have more agressive lifts, which will in turn build a bit more compression, as I understand. Are stock heads capable of this extra pressure? This is not going to be a race rocket, just a bit more responsive summer drive.
By changing the cams, will the fuel economy is heavily affected? Currently running 1641, and seems to be running hot. My Beetle is a Cabrio so it has lesser cooling intake.

WEB CAM.....is now $$$$ yea they are great. I like the price and grinds a bit of scat. c25 1.25 rockers. Even the C20 with ratio rockers.
Like always great advice my first build I following your advice and that little monster is 15k miles and running strong
Thanks
Nice work!
I gave the 1.25 Rockers to my wife for her dune buggy I rebuilt. It gave it a little more pop. And in that fiberglass car it moves good.
Yea they do help a bit. But the Duration on the stock cam is way too short. need at least 250 or more duration I like 265 or more.
@Mikefngarage Yeah I tried talking her into a w100.
Well said Mike. I am

yea that cam is great.....Or try Scat they have a few that are cheap. But most I think need ratio rockers. C20 C25....1.25 rockers. Cheap prices

stock reground lifters are great.

I kindly ask do I need buy set of performance lifters?

Thanks a lot. I got the measurement size I'd asked sorry for many qns.

Hey Mike ! Holley bug spray carb. N-O G-O O-D + gas guzzling black smoke producing waste of money ! nice chrome intake .
yea I have one of those in the shed......NO GOOD I totally agree. lots of black smoke , lots of fuel use and NO POWER.....
Excellent information, thanks.
And im available Sundays and Mondays :)
By changing the cams, will the fuel economy is heavily affected?
Currently running 1641, and seems to be running hot. My Beetle is a Cabrio so it has lesser cooling intake.
Is the ingle 110 good for bug or bus ? Thanks
Cool man thanks for your input
Great info! Thx Mike
I built a floor sweeper 2332cc with a stock cam and it was a torque monster. Every part you change from stock just makes it worse. LOL
Mike what’s your thoughts on line border thanks buddy 😊
