2.1 8v build

[Swys]

Hi guys is it worthwhile to build a 2.1. What is needed for the build did my first 2l conversion and i love it . Planning on building the 2.1 for my caddy any advice wil help thanks.

[Darrien]

in my opinion it is worthwhile,loads of torque

assuming you are going to leave your std block complete...

parts you will need

- 2l block -2e or ady (if 2e,make sure that there hasnt been line bore done to the main caps or you will run into a issue with the crank weights touching oil squirters)
- 2l rods
- 83.5mm pistons or bigger for the actual 2.1 effect
- 038c tdi crank
- tdi crank original crank gear bolt
- and the obvious rings,bearings,oil pump etc...

things to be done (assuming you've bought whats needed)

- bore block to intended bore size
- if std crank was bought,the nose will need to be machined to fit the 8v crank gear
- crank gear hole (where the crank bolt goes through) will need to be drilled slightly larger to fit the crank bolt
- crank bolt will need to be shortened as it is to long
- top of pistons will need to be machined as they now will protrude the bore,how much is dependent on your application,whether it be a everyday 95 pump fuel car or a weekend ethanol car etc,get good engineers to do this,guys who build cars,as they can measure your comp ratio for you and not just chopping and estimating

- that is more or less it,or atleast as much as i can think of at this hour
- goodluck on your build,pm me,ill be more than happy to help or assist as ive built a few
- i apologise if ive forgotten anything,im sure ill remember in the morning

Goodluck

Good detailed info Darrien

This post reminds me of Torker, he is an addict of 2.1 motors.

I also have my first 2.1 motor, but in 16v.

The 8v will give awesome low down torque if you fit the right cam. 16v's make power higher in the rev range, again dependable on your cam choice.

It is not as fast revving as the short blocks, but really make great power all the way through.

thanks guys
