Nitrous is an imaginary turbo for n/a engines.

Preloader, i bet you could plumb direct port nozzles in a way that would look like a piece of art.

i have never really been a fan of cheater spray. If the K03 needs motivation to get to work i will be very surprised.

No n2o in my plans anytime soon.

It will be fun but I genuinely believe it is a bridge that you should wait to cross until necessary. Mainly because of the cost and time spent installing could better serve you if spent somewhere else, like your second engine.

With or without it you're going to have one kick a$$ engine!

Also boost lag and boost threshold are two different things.

The boost threshold is the area that the right turbo can put you in your desired range.

Boost lag, largely has to do with driving behavior. Keep above your boost threshold, and boost lag will be minimal.

MZ0 is going to pay dividends with my new turbo's higher boost threshold, cause I'm rarely below 3k as is.

Preloader, what are your thoughts on internal vs external wastegate?

 

[Preloader]

Internal offers much more simplicity and requires less space, which is valuable for obvious reasons.

External requires much more complexity in the exhaust mani, and the freer flowing bypass won't provide much gains on such a small displacement in my opinion.

 

[DevilSonic89]

Im going with internal

K03 Replacement Turbocharger Turbo 1 8L FOR Passat AND A4 | eBay




okay i have found that same turbo for a little cheaper. i was actually thinking of getting it myself

 

[Sonicpizza]

Guys what about a centrifugal supercharger??

Guys what about a centrifugal supercharger??

I have thought really hard about this one, i want to pursue a m45 s/c with in the next couple years.

Issues with s/c vs turbo is the room factor

 

[Sonicpizza]

Yeah. Ive seen a integra with one they made a bracket with a belt and what looked like a half axel that went acroos the front of the engine(above headers) and connected to the s/c. It worked but thats alot of calculations and even more weight. And i cant think of a place to connect the belt. Usually the kits for cars come with a bracket that mounts where the alternator goes and it has a double belt pulley. The alternator is where i was thinking of attaching the belt, just steal a pulley from another car and put it on there. I found a Paxton sn93 for $300 on cl, and its not an overly huge one it looks about the right size for the 1.8.opcorn:

 

[Sonicpizza]

I was looking into it further and itd probably be easiest to just have a double pulley made to replace the current one on the water pump.

On another topic, nobody makes any performance rods, pistons, sleeves, cranks, cams, retainers, for the 1.8......what can we do?
