Too much fuel is what melts things..   Too much boost just plays hell on the head sealing to the block..  Ask Kevin how he knows that..  ;D

The compression ratio for the 1.6D is 23:1 and the 1.5D is 23.5:1.

There's other option for cams and that's through Giles, they're call high performance but they'll probably get you better mileage too.


Sweet, I'll look in to that. Going to pick up another engine stand today so I can tear it down. Time is really thin with me at the moment.



Who sells cams for the 1.6?

I was old anything over 6lbs boost on an NA engine will melt the rings. Anyone confirm?

How can you tell the rings melted when they're fused with all the surrounding bits?

Typically the rings don't melt first, the piston does..   You'll be able to see obvious damage to the piston..

but i can tell you its un-true as hell.. i run around 20 psi to my n/a all the time.

Do you run squirters in this motor, I'm asking because of my knocking TD that has just been installed and the previously fitted perfectly good NA is sat on the floor. I've not used the NA because of the lack of squirters.

im running a n/a.. (it came out of a vanagon, and they NEVER came with turbos that i know of.)

if it had squirters, i would call it a TD..

its a 11mm n/a block.. stock fiber head gasket..

the key to not burning these engines down, is not about keeping low boost, its about keeping the fuel in check with the right amount of air. thats why i can get away with 20+ psi.. i have enough air in there to keep the burn nice and lean.

Yup they did, look on ebay, someone usually trying to sell a TD vanagon engine.........
'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

FYI-surfacing the head will raise your compression ratio zero-its already flat. And if you surface the block .010 (DON"T!) you would only be raising CR by maybe .2.(21.0 to 21.2) And your piston + valves are closest at (apx) 8* before tdc for the exhaust-and (apx) 8* after tdc for intake.
