How do you Rebuild a 16v

[GoLfMan]

if the 16v has a blown headgasket and stuffed rings, what is required in order to 'refresh' it properly.
reseat the valves

The price of a litre!

An oil burning 16V might not need new rings but if you are pulling it down then they would be worth changing.

I would definitely be changing the exhaust valve guides on any motor with 100,000 miles/160,000 KMs.

I wouldn't toy around. I'd get a complete rebuild kit for piece of mind if I didn't know the history of the engine. That said, you can tell a lot as soon as you pull the head off.

You can either re-sleeve the block - AFAIK gtimk5 has had success with this - or buy oversize 83mm or 83.5mm pistons. The stock bore is 82.5mm.

www.eurospecsport is the place to buy parts.

16v on 45s is hugely expensive: you need a good manifold, properly jetted carbs, a tune up, a new ignition setup (most yanks use MSD - also not cheap), an ABF water outlet (with some manifolds) etc etc. Not cheap

so you can buy a full rebuild kit!
A friends dad has the full porting and polishing kit so we will be tucking into the engine with porting and polishing (when i get one) as he is keen to help me build an engine.
so its more economically viable just to convert my carby car to fuel injection? but im not looking at a cheap option, im looking for the power and straight forward option, which ever is easiest to obtain the most amount of street power possible.
thanks for the link Valver!

[GoLfMan]

just had a look at the site Valver and I didnt see any rebuild kits that you speak of?!

[Valver.]

I don't think Eurospec sell the rebuild kits, but they're a good source for pistons

These guys - http://www.mjmautohaus.com/ - claim to do the best deals on 16v rebuild parts, so send them an email and suss out what they can do.

I ordered all my replacement parts from here:

https://www.parts4vws.com

https://www.germanautoparts.com

https://www.gsfcarparts.com

Had great service from all of them. Someone also recommended http://www.carmadillo.com/ but I never tried them out.

And, most importantly, here's how to rebuild a 16v:

This pic is very helpful, too:



Vortex is the place to go for 16v info. The threads are endless.

If you dont want to go crazy with the rebuild GolfMan, a lot of the parts are the same as an 8v motor. Headgasket and Rings for example.

You could hone the bores, put new rings and then do some headwork, port and polish and a skim. You`d end up with a nice rebuilt motor, but wont have spent silly money.

If you start buying pistons and resleeving blocks it gets expensive. Even a stock kr engine in a Mk1 is gonna haul ass.

Throttle bodies are very expensive, use factor fuel injection, or go aftermarket. Fuel is never gonna get cheaper.

Hey Valver, I know you've had ABF's in the last 2 cars but do you know where I could find 83mm or 83.5mm pistons for a KR? All the aftermarket 16v pistons I could find were for 9a's or ABF's, except for the ones TSR used to sell in the 1.8KR to 1.9KR rebuild kit

thanks for that info Loon. Porting, Polishing and port matching should release a few more killowatts. What about grinding the cams to a more agrressive lift?
what do i need for a injection conversion?

Gav was saying you can use two exhaust cams in a kr head and that gives more mid range power.

Fuel Injection you need a diesel fuel tank and bigger fuel lines and a fuel pump to suit the application. You need different pumps for kjet and aftermarket. If going aftermarket computer, you can use a cheaper fuel pump

so how much all up would be the tank, lines and pump etc and how hard to install?

You need a modified chainwheel to do the twin exhaust cam mod, mine arrives in 2 weeks.
I don't see the point in modifying your engine to give more power, and then using cheap fuel(debatable weather it gives you worse economy also).

[GoLfMan]

did you miss-read mate? its cheaper fuel pump...
but yes i also agree that modifying your engine then using **** fuel is useless... its like putting water on a fire really.

back to it!
so why do you need a modified chainwheel?
