Hi
I have a 244 I've been tinkering with on and off the last two years. Thanks to a forum member here or elsewhere I got the thing from not running to running pretty ok on 4 cylinders. It's been a bit of a battle involving taking most everything apart save the longblock itself.
I have decided to sell the 244 but keep the b23ET due to their potential and rarity, even in Europe (where I live).
Here's my problem/question:
This thing now starts, runs and idles. Doesn't idle smoothly. But it idles.
It starts to break up under load around 3k rpm, sometimes 4k rpm.
Fuel pressure is set to 3 bar and. It's got green injectors (stock?)
The turbo is a T3 Garrett.
Other than breaking up around 3k, sputtering and so on, it's slow. I can feel boost just starting to build and then it get's unhappy.
When checking the timing belt it seemed to be a tooth, maybe two teeth off. This wasn't comparing crank to cam gears (pulleys still mounted in the way) but by putting it at true TDC. The cam seemed a bit advanced dot on pulley b4 mark on housing)
I've had a motor start and run 1 tooth off so I know that's possible. I'm building boost although yet to measure how much.
The Motronic unit in this (only used for 84/85) does ALL the timing so adjusing manually does nothing.
Could it be that my timing belt is just off a little, do Redblocks still run? I measured compression as it's setup now and it seemed high if anything. I measure around 13 bar per cylinder!
Thoughts?
