hey tech heads,,, got a few 2 many questions 4 u guys so here they r...
is $6000 enough 2 buy all the parts and get whatever machined and what not 2 build a 1916cc race engine.
ive got a guy i know to build it 4 me 4 cash and beers and he knows what hes doin, but i just want other oppinions.
i would prefer a engine 2 race around a track rather then down a quarter..
and would i get100hp plus??
i want someting that i can drive daily,,and would last a good time..
ive watched ct race and some pobjoy cars race, could i build someting similar???
Yes and no. To get daily drive, reliable, and powerful won't be cheap.
Depends on exacly how race you want to go, and how much power you want. I think you will be looking at 10K+ a 1916 or greater race motor (thats with all the goos stuff)
I have no sympathy for my car, only the wallet that pays for it!
Go hard or go home!!!!
looking around for bargains, yes would come in around the $6K............depending on your patience and penchant for particular materials/brands/qualities..............
if ur building it urself, i'm not experienced, but i been shopping for all kinds of bits on ebay and what not, but purchasing over the internet will save you HUGE bucketloads of money.
I found this great site that comes with great vw engine rebuilding kits from 69mm to 78.8 mm counterweighted cranks and from 87.7mm to 94mm pistons + barrels, come with performance cams too. Mainly Scat and BugPack brand too.
The U.S. Dollar is weak at the moment, so its good timing. Its just the shipping u will have to price, as well as the tax you wil ahve to pay if your importing something you paid more than a grand for.

Heres a pic of their kits. All you gotta sort out then is the little bits and the case. But its practically a long block. If you chase up shipping prices and what not, give us a buzz hey.
Gday Chris thats a really tough question because there are so many variables.You can typically go 2 ways,either buy the parts yourself and build or get somebody else to build your engine or,buy a complete engine of someone like Stan Pobjoy or Rod Penrose
For sure 6k is a good start but there are so many extra things that come up when you start chasing hp.Its very hard to get good hp out of your engine and still drive to work the next day.CT has managed but his engine is a freak, and he really keeps it in top condition and tuned to perfection.
My personal engine to replace is just to scarey to think about but lets say if i spent 12k i would not have any change
My best advise would be to talk to as many people as you can then form a plan.Cylinder heads are the secret to big hp so get a good set if you can, and dont rush ,wait and get the best rather than saving a few bucks and getting something that may fail down the track.
Hope this info helps a little
My donk has 100 at the treads. Colin's has over 130.
I'd love to have 130 at the treads but that spec may not be as reliable with all the miles my oval clocks up (But it might be).
Here's my 2 cents, I'm no expert. Hopefully you'll only have to spend $6000 once.
Don't get pursuaded by 'bigger is better'. I went wrong with some 44 x 37.5 valve street eliminators. Keep things conservative if you want reliablity and get good quality parts. My engine has 40 x 35.5 valve mini D-port40 heads and under 0.500 valve lift and 9.6:1 compression.
Get good quality webers like the old ones. If the casting is a bit rough don't touch them. My car pissed fuel all over the engine when I was racing at Eastern Creek on the cars second ever track day because the spanish webers popped a plug at the bottom of one of the float bowls.
Keep the carbs balanced with a balancing tool. Make sure the linkages are in sync (often). Get used to clearing blocked idle jets with 44 IDF webers. You'll need to access them though the inner wheel arches. Make sure you've got a good reliable spark with a pertronix (or similar) and an MSD (or similar). Then the thing will run sweet, sound sweet and be enjoyable.
Use good oil like Motul or Castrol 20/50 Formula "whatever they call it now" and check the valve train religiously. Set the valves by rotating the engine until you feel the valve start to open then go back half a turn so the lifter is on the heel of the cam. Doing the valves at TDC is unreliable due to overlap if you have a long duration cam. I set mine to TDC and then Jak showed me his way and it was amazing how the gaps opened up more than what I'd set them up at. After that the engine sounded less tappety.
Always check unusual noises coming from the engine bay. Like the screams of small children!

Wow CT - I've never heard of that way of doing tappets - have to give it a try I reckon !!! 👍

hee he.......or get a good pulley with 360'of markings and check it to be true to the crank position when you build your motor!
YES CT and COLIN.......the reliability and h.p comes from a good combination of parts not necessarily the biggest or baddest.
match your capacity, cam and heads to a goal output, very important😎
Regarding adjusting Valves. When I worked in a VW shop many years ago and we would do many services at once on air cooled cars.
A trick that I was shown was to set the valves without standing up and down to turn the motor over.
We would 1st remove all the plugs and let the handbrake off, put the trans in 4th gear.
If working on hoist I would adjust one rear brake so that it would lock on, its a good time to adjust brakes anyway, then turn the other wheel to get the correct valves rocking, then release the brake and do the same on the other side.
If working on the floor you can do the same thing, but I was always able to hold the opposing wheel with my foot and turn the other wheel with my hand.

PS, off subject but $6000 + for 1916cc with about 100 RWHP makes a Suby conversion look attractive
if you buy every thing straight from the state's yeh it's possible.
your head chioce is one of the most important things that you need to decide.if it don't flow it don't go.cam is next.based on what the heads do.
make sure you do plenty of research,and when you think you have it all sorted,start again
the biggest problem with your budget is how much of it has been alocated for beer and how much will be consumed before the building will be comenced.
i have seen some mistakes made while building completely smashed on beer,car still ran 10.1 @ 116km/h 1/8 mile in a heavy type three.it did last all day.but the drive home was hell.the mistakes were minor but the engine is known a the one day screamer.
have fun in what ever you decide.
Research everything, then do it again. Damo is on the money, you must match heads, cubes, cam, carbs, comp ratio, combustion chamber design. I've seen big dollar engines not make hp, and visa versa. Biggest mistake is to always be thinking of the dollar. As they say in 'how to hotrod your vdub engine', there is no substitute for cubic inches. For a daily, I'd be thinking more displacement, less heads, unless there is bacing rules or whatever to consider. My 2332 makes great power ( possibly 130+ atrw), very drivable, but although I'd take to the shops anytime, I'd hate to rely on it for everyday to get to work.

Stan’s the man, not many high performance engine builders offer a warranty.
Were all driving 30 year plus vehicles, to some any modification to a vintage car is abhorrent. In most cases any modification you do to fit an alternate motor can be undone. My old 1302 was water-cooled for 16 years, it’s now back on the road, air-cooled.
I could not agree more with you Matt ,its easier to get 100hp from a 2332cc than a 1916cc but it comes down to your plan.Chris you mentioned racing ,now most clubs run different classes based on modification and engine capacity.As far as hillclimbing is concerned Nathan,Craig,Heath and myself run in Improved Production 1600cc-2000cc.
Now if you build a 1916cc motor you will run 1600cc-2000cc but if you go a 2332cc for instance you will be in the 2000cc-3000cc class, a big step up. So as Matt said do your homework and have a plan.
Hows your gearbox? Remember no point having a street stormer if your gearbox explodes every time you drop the clutch.
ok guys, how bout if i built a hot lil 1640 or 1776, but one that i could build up 2 a screamer 1916 in the future????
and yeah i do have a stock gearbox, but not thinking bout that at the moment.. the guy i bought it off did have a type 4 2.9L
that he said makes bout 190hp, supposably, with the stock gearbox.dunno how much he was dropping the left foot though.
ive been enquiring bout a 2276cc combo thats maybe 4 sale,owners not 100% SURE YET...its in feb april 08 aussy vw mag. what u guys think bout that 1 4 circuit racing and bit of a daily driver as i have enother car??
i know stan from when i lived over there cause i was from coffs as well.used 2 go 2 a few hillclimbes with him, AND YEAH HE DOES LOVE A CHAT,he,he.
his engines is what i have been saving for, but so far im still a few g's off his base 1916cc engine.
should propably keep saving 4 that.
Did you used to tag along with Stan? Did you go to Mt Cotton and Grafton Hillclimbs when Greg Ward and I were there?
If you're going to get your case bored etc you may as well go for a 1916 instead of a 1776. I think it's the same price. I'm sure somebody will correct me if I'm wrong.
First stroker I owned in 1987, I said I'd never go stock stroke again. Having said that, I have had success with strong running little motors (1776) where you can put more money into refining the little things, and overall your little motor can run cooler, but 'big has balls' that you never get with the little rever.

So you have another car.Well that puts you in a very good position.I didn,t start to make real gains in hp until i decided to bite the bullet and not registar my car at all. CT is right you may as well bore for 94,s as 90.5mm barrels and start at 1916cc.

yeah Matt, i was ten years behind on my OWN first stroker, but racing Luke driving hardings targa car, and Pigmi with his 1776...........both more refined by an expert company😎...over my swap meet special 2180 ......made me realize how well these little revers could go also!...........amazing how equal they were despite the different style of power delivery. pigmi and i ran almost identicle et's that weekend but.....
yes there is no torque like that of a stroker tho when you pile a couple of mates in our little cars to show em what you've got. the grunt shows up when approaching the big speeds with the stroker
make the decision up front tho, as said..........a change in stroke "down the track" should mean different cam, valve size, porting, exhaust and carburation to make the most benefit from the upgrade.........ie, totally different set up🙅
should we turn this into a confessional as to how much $$$$$ we've spent in our pursuit of reliable power?........ as Colin has so generously confided
Thou shall not confess thy sins, to thy girlfriend, in relation to dollars spent in the pusuit of horsepower.
Chris, I still have a copy of the video you did at Grafton. You were filming Greg Ward on his last run when he spun it coming onto the straight. I remember your comentary, in a Bill & Ted's Excellent Adventure style, you said "..oh... spewin'! He's gonna be pissed". It cracks me up.
Damo what a contest that would have been.
Amazing you got to see a direct comparison with three very diferent engines.
For the un oldies; Pygmy's engine: 1776cc, Engle 120, 40x35.5 MB ported rever,2x 40 IDF
Targa car :1300cc, Engle 120(?), same style heads (probably the set after Pygmy's?)2x40 IDF
Damo :2180cc, ? ,? (feel free to help here Damo)
The Targa car was built for rev's (my combo afterall) and she saw 8000rpm regularly, which I think is very sustainable with the right components. My old drag engine on the other hand, saw 9000rpm and I feel the need for the Chev valve springs and spring pressures needed to achieve this, make the streetability unreliable. The 2332 I now have, sees 7000 and so the dual Scat springs are so much easier on the rest of the valve train, it is more reliable. I am presently building a 2165 with small carbs, and it will be rev limited to probably 5500, as the budget is small, but it will have 'balls down low' (said with a deep voice). With the availability of affordable (remember there has always been cheap) stroker parts, I feel cubes is the easy answer for street power.

2180,all good gear, lightened and balanced, 48's, berg 310 (which was very nice), BUT performance down due to it's heads.... out of the box 041's yuck!..........
........poor porting, shrouded & silly match of valve sizes for engine capacity and cam needs, also poor combustion chamber design...........low compression to keep the heat under control............it ran out of puff by 5600rpm
fast in it's own right and i was not dissapointed with it, but other combos (smaller & better match) could provide the same performance
which leads us back to IT'S A COMBINATION of well planned, matching parts that will provide the best results.
there was the articles on Jurgos yello zonker (V.V.D.S) all those years ago to get the most from his small valve heads with great results
Craig Torrens6 times Australian, 7 times State Hillclimb Class Champion
If you want to keep it under 2lt then IMO the best option would be to stay with the 69mm stroke crank and increase the bore size to 94.......the good old 1916 combo.
If you want a larger than 2lt combo (type 1 motor) then you will have to use a stroker crank.
IMO the under 2lt stroker combinations just don't cut it.
The strokers can't compete with the 1916's in hillclimb, and its been that way for well over a decade.
In hillclimbs you need torque for out of corner "punch" as well as a very wide rev range for less gear changes, so a 1916 is more than capable of producing both.
As for $6000 as a budget......well I built a great 1916 for the ragtop for less than $4000 using Pobjoy as the builder.
Just buy the parts when others are selling them cheap 😎

Sorry I cant agree.
All things being equal, more cubes is more low grunt.
