Can 8v swap with 16v?

[metalman1004 0]

Curious as to whether or not a 16v non-supercharged head be swapped with the G60 8v head? I have an 89 Corrado G60 8v and I cannot seem to find alot of information on the 89 Corrado's anywhere. Seems I happen to purchase the misfit Rado! And being new to the scene has left me out of the loop when it comes to swaps and any other modification information. :bonk:

all factory G60 Corrados had 8v engines, with the exception of a few one-offs (if that makes sense)

 

it is possible to build a 16v G60, but not a 'simple' head swap, it's a very involved engine conversion and some of the parts would be very difficult to source.

Ok. Thank you. That makes perfect sense. Would it be smarter then to just stick with the 8v head? I'm trying to think of smart HP improvement aside from boosting the chargers PSI [because its such an old engine with high mileage]. Primary concerns right now tbh are just improving the exhaust along with the audio system. Everything else will be tended to if the car pulls through long enough

Tis a bit of a rocky road, G60 tuning. It's a sweeping generalisation here but most G60's I've known over the years who've gone beyond the basics (small pully, chip, larger intercooler) and gone into engine modification rarely ever run right and never last.. so many disillusioned owners just end up getting rid of them and moving on.

 

For the G60 all I'd do would be smaller pulley, bigger intercooler, remap.. you can see a reliable 200BHP with that easily :)

Thats sounds like a brilliant idea! But do you think it would be wise though on a car with such high mileage? [200000k+] And also. What all is involved with a remap on these? Im more used to OBDII Hondas than I am with these. Tbh, I'm totally clueless when it comes to engine tuning on the Rado's, or just VW's in general :cuckoo:

To be safe you need a freshly built engine if you are planning any power increases.

VW were (and still are) good at overengineering their cars and engines, so conservatively increased power outputs don't reduce engine life terrifically, but on a tired engine you are asking for trouble.

If you were going for a reliable 200bhp I'd look at stripping and rebuilding the bottom end, with VW bearings of course. If well cared for, the crank and pistons should be reusable and the bores a flick hone. A charger rebuild by a reputable specialist (if these blow you can say goodbye to the whole engine) and then a chip tune to match your car are also essential, a destroyed engine, either because it or the charger are on their last legs is going to write off the car value wise.

None off this comes cheap, but it's worth doing properly.

All very useful information. Thank you sir. And instead of rebuilding the bottom end and possibly having to get the block machined, do you know where i can purchase short blocks for these cars? Ive heard of BBM but they dont offer a 1.8 short block and they want atlleast 3000 for a 1.8 longblock! And thats is beyond my budget. I just want short block in good condition to replace my current old timer [nearly 300,000k], and take up to 200 hp as daily driver

I'd look out for an audi 6A engine (A80 and coupe), same engine as the 9A short block 2L, but just a different sump pan and oil pump pickup pipe. I've opened those up and there's been next to no bore wear on a 150K car, especially the auto's, they get an easy life usually.

Then, if you find a good-un, replace the bearing shells and if you want to go a bit further, take it to bits and have the bores honed and perhaps new rings.

I'd imagine that with budgeting around 100 quid for the engine (might take a bit of searching as they are becoming rarer) you could do the lot for £300-400. That's based on the crank and pistons being serviceable.

worth a read,

very useful post. i think a hybrid like that is beyond my VW knowledge at this point. maybe somewhere far along in the future. right now im just focusing on finding a rebuilt 1.8 g60 shortblock to start my journey. something significantly younger than my current engine to have something reliable to work with. and it will all be fun from there out. :norty:
