Dilemma - 2.0l 16V or G60?

Hoping you can help out here, I want to upgrade my GTI with a powerful engine. I'm after a worthwhile upgrade, so for that reason 1.8 16V and 2.0 8V are not being considered. I figure, what's the point in investing a lot in either of these when the 2.0l 16V exists, and would give better performance?

I've done a lot of reading around and I have a good idea of the parts required for a 2.0l 16V, also I understand that the advantages are that it gives good torque, as well as decent (top end) power, so even a tuned motor retains good driveability.

But, the G60 also gives similar levels of performance, a different way. I know that a G60 would need a bit more in its wiring (electronic engine management, rather than K-Jet) and also you need to find space for extra pipework and the intercooler.

I have a ballpark figure of 175bhp (flywheel), which is easily achievable on the 2.0l 16V using a ported and polished head, balanced bottom end, 4 branch exhaust manifold and 2.5" exhaust and the KR inlet cam.

Thoughts anyone?

how about a 1.8t with megga squirt? should get more than 175bhp, and loads of tourque.

I'd avoided turbo because I don't like the way they drive, I wanted to retain as much low down torque and driveability as possible. Also, I don't think I'd be able to afford this kind of conversion, for example how much do 1.8T engines start at? I know that Megasquirt is a logical way to go though, around ?300 and it avoids a lot of hassle trying to wire up the later cars ECU and dash, etc to the Mk1.

Paul - I've mulled this over myself and would go 2.0 16V. G60 great, but potential supercharger problems scare me (servicing costs / massive bill if needs replacement, etc). I had a Polo G40 and it was always a 'back of mind' worry. Benefits of 2.0 16V = loads of donor cars inc. Audi's (ie, scrapyard sourcing) easy/cheap to get spares, no intercooler to worry about, and easier to do the swap in the first place.
I'm sure others will have their opinions though ……..

im biased but G60 defo, the sound, low down torque. just keep on top of the servicing ie regular oil and filter changes esp, use quantum silver as people say fully synthetic is too thin and can get passed the seals in the charger.  How about seeing if you can get a go in each type of conversion too !!

Any offers for a ride in a G60 and 2.0l 16V? in the NW Area???

How about a 2.0 16v G60?! Use an 8v bottom end with a 16v top end (will lower compression) and get a supercharger on… Have a look for eaton chargers as they are much cheaper than the g-lader units by all accounts…

I would personally go for a 2l 16v on megasquirt…

I've considered building it all up as a 2l 16v, then adding ignition control (eg MegaJolt) which would allow me to run a bigger advance, yet avoid pinking by mapping around it. I read on another forum there was a guy who saw 10-15bhp gains by advancing the ignition, but it was pinking really badly at certain points.

Soome good info in those links… Pretty tempted. Got to get it on the road with the 1.6 in first though. I nearly bought an audi 16v off ebay for ?150 yesterday for the 6a engine but the g/f would have spat her dummy out at that!

Paul,where abouts are you? anywhere near burnley?

i am stupidly,stupidly! busy at the moment,but if you are near to me and can get over some time,ill take you out in the rado.

Well, I've decided on the 2.0l 16V route, mainly for cost reasons, although I did some planning and to achieve similar power levels, I'd have paid similar money. Anyway, here is my shopping list:

9A engine
4 branch manifold (Ashley)
Exhaust system (Ashley)
Mk2 16V gearbox (secondhand)
Cabby (100mm) driveshafts         
Port & polishing of head
KR inlet cam            
WUR               
Upgraded engine mounts            
Oil, filters, bolts, etc

Can anyone spot any obvious high-value items I've forgotten?

Paul - you'll need an early Golf Mk2 16V air filter box to sit neatly on the chassis rail as they're comparitively small. Late Scirocco's may be an easier to find source for the driveshafts too.

A CLUTCH UPGRADE MIGHT NOT BE A BAD IDEA WHILST ITS OUT :wink:

Cambelt too, while its out.

I used the mk1 airbox and just swopped the top bit over, as they are a straight swop (on KR anyway).

Also, fuel lines need moving, i replaced mine.
