need more ooomph

[mearnsy]

My 1600cc AC engine just has to go, it al works fine but with 5 of us travelling its just too slow.

Im not bothered about being air cooled any more just need more power, what is the easiest and most cost effectibve engine replacement??

[Laurie]

Maybe the addition of some CCs may help.

Seriously, any suggestions welcome.

Have a word with 'groovy'. He has a totally stock CT with 1776cc and lower compression, about 70 BHP. Add a pair of single choke carbs and you'll have around 80+BHP Or Kinky Mick of the Happy Wheel Shack has a 1966cc CT with about 110+BHP. I've done about 20 CT big engines over the years. Mick has a cog box gearbox and does 3500 at 80MPH and when he's sensible, gets around 30 MPG

that was serious change it for a 2lt.
lots have done it and from what I have heard they have been pleased with the conversion.

CU engines were the lousiest type 4 engines VW built! There is an alternative, if you're ready to go the distance.

Heritage are selling VW 1800cc industrial engines. I recently autopsied one and found that they had 6,300 rpm rotor arms??? 36mm solex carbs???? Big valve 1800 heads???? Definitely not for generators!
Lovely engines, around £800 then you need to convert it to take CU tins etc. Only awkward bit is the heat exchangers which will convert if you can weld.

Further to my first statement. The CU has a horrible habit of losing valve seats, likewise valve guides. It produces 68BHP where it's earlier 1800 forebear with the 36mm carbs, made 80BHP. Hudraulic tappets were 'power thieves'.

Back to my serious suggestion. if your tins are good and your exhaust system is good, then a 1776 cc conversion will give you a better engine than the CU. Plus if a head dies, you'll be buying BEETLE heads at 80 quid new, not Cu heads at £200 each. 1776 Barrel and piston kit is 175, less than the CU kit. If you have alternative heating, the CT will take the 2.1 water boxer exhaust with the better support and flow.

Stick the 1.9 water boxer crank in the 1776 CT and you can use the 228mm clutch and have a crank that wis over engineered for the job, rather than under engineered.

If you can do the work yourself, then the CT case can be machined by anyone who can machine a Beetle case for 1776. Just work out your compressions and the carb will run the bugger too!

This sounds like a good option and was recommended by a friend at the weekend, can anyone else recommend this and posiible give associated costs?

PS Cant find groovy?

Not cheap..........

[dekker]

Just done this with my 1600CT. Cost me
£140 for excellent 2nd hand engine, crank, block and heads mint
£100 good 2nd hand 90.5mm B&P
£100 machining work to block and heads (included equalising vol in heads)
£10 2nd hand type 1 camshaft
£10 2nd hand type 1 push rods
£70 solid lifters
£50 bearings, gaskets, push rod tubes etc
£20 spacers to lower compression.
Thats about £500 but I've got a reconditioned 1776 motor. Twin 34 ICTs next.
Accept that 2nd hand CU cheaper but theres a lot of crap out there.

Main problem I've run across is that very few people know anything about this engine when you try to buy stuff and give you duff advice, exception being Laurie on here.
Cheers, D

Having just read the article in this months volksworld camper mag about 1641cc barrel and piston kits i was wondering if this could be done to my 1600ct?

The cost i believe is approx £120 which makes it very attractive.

Need more oomph for the A286 Hills!!

This is - sort of - being discussed here;

I've stripped an entire engine and just replaced one faulty valve in the past but it depends what kind of mileage your engine has done. If its an old 'un I wouldn't be shoving bigger pistons and barrels on without checking at least the endfloat, main bearing wear etc. The sudden increase in compression on a sloppy engine can often polish them off. It can be done yes but not without risk unless the engine is in otherwise good condition.

nice to see people actually talking about upgrades to the CT's - they get a really bad time -far worse than they really are...

People don't seem to realise that ALL VW engine's are sh1te!. The CT was just different in layout - not naff in reliability - it uses all the parts of any other vw engine just some type 1 and some type4. I'm pretty sure that if you put a CT in a beetle it would fly!

OK they are not as powerful - thats due to the fact its a smaller engine! (I don't figure how smaller cc's = a poor engine!)

Anyhoo I should hopefully be able to vouch for the 1776/twin carb (and remote oil cooler) conversion soon enough as this is what has previously been done to mine

We recently had an earbashing on VZI for having a CT! Until we - repeatedly - explained that we were only trying to keep one engine (we have 3 of them!) running long enough to 1776 another!
