Rebuilding a T4 1.8 with so many ?'s

[gsusmaniac]

I am currently rebuilding a 1.8 out of a 411/412. I have so many questions and dont know where to start!

First off, I have the entire engine dissamsembled.

Here are my goals for the engine:
1. Want to try and keep it as reliable as possible!
2. Want to make it a mild performance engine (130-150 HP)
(dont know how possible it is)
3. Want to do it within a reasonable price.

What I have learned so far...
I can go with the 96mm pistons that are still slip-ins and require no machining. However, the ones I found are the KB's and are $525. Just a little out of my range.
Are there some somewhere that are less expensive? So far, I have only spoken with Jake Raby.
Also, does anyone know where I can find a shroud that has been converted? The DTM is the one I would really like, but runs $600.
How much money am I looking at in the long run, to get this engine in my car?

Pretty much I am looking for any information that can help me out! I am a college student and working 45 hours a week. I have fallen victim to the VW addiction and just have a desire to keep on making mine better! All advice is welcome.

Yep, I know the feeling..

I can only chime in on the shroud. If your going mild, then maybe a Next Gen Conversion may fit your bill. Its a do it yourself upright based on Type I parts..

Not sure if it will support the HP you have indicated, but food for thought..

One option could be stock replacement 94mm P/C set for a 2.0 bus $229 from CIP. I'm not sure about slip-in or not as i've only built typeI HP motors so far, but two weeks ago i got a 2.0 typeIV long block out of a running '77 bus for free . I plan on using it as a core to build a 2.5 RAT. I would have to say don't cut corners on your cooling system period! You wouldn't run a water cooled motor without a good waterpump and radiator would you? Getting your heads, crank, rods, rebuilt, and new cam and lifters plus gasket kit, and conversion flywheel and clutch and pressure plate etc.... You might stay under 1k minus cooling system. I'm not trying to wreck your plans or anything, but there is a bit of $$$ to stuffing a typeIV (i'm assuming) in a bug. The transmission has to be considered also, and exhuast. You can do it, even if it takes a little longer to save the cash. It will be well over a year before i can even think about buying the 2.5 kit.

He has a 1.8 crank. The 2.0 bus pistons have an incorrect pin height and are incompatible with the 1.8 bottom end..

And with a 13cc dished piston getting any CR from the engine would be a big challenge..

Holy crap, Jake Raby is everywhere!

I got all the answers I needed from Jake. I am going with the econo 96mm pistons and the 9130 cam. I assume that I can use my same crank and rods? Hopfully!

Jake is a tremendous help and from what I read sells the best parts! My next step is trying to make enough money to get the DTM shroud.

Yep, Jake gets around. He must have a secret room with pc's logged on to every aircooled forum on the planet 247.

Thank's Jake for clearing up the 94mm piston issue. I wasn't sure if they would work. I'm just learning about type IV's myself as i said in my previous post . I just like trying to help and learn all at the same time.
