Newbie alert! Opinions on motor I've just bought (in bits)
 

OK, this engine was running last year and had a damaged piston, was stripped down and checked out by a well known (for type 1 motors) UK independent professional and everything else was OK. Got the motor at a bargain price by the way. Anyways, it comes with new replacement barrels & pistons (J&E) which are 103mm, new total seal rings, a 71 c/w crank, unknown aftermarket cam, ported 48x38 heads, porsche shroud cooling (unknown manufacturer), BAS exhaust, 44IDF carbs.

Now I have a couple of questions:
103's - good or bad? I've done a little research, some say theyre fine, others that they're not. Opinions?

I've built type 1 motors before, what other things should I take into consideration when building up a T4 from a pile of bits? Are there any other things to look out for.

What kind of power & torque outputs would I be looking at from this motor?
Now, what about maintenance? I'm a bit religous with my maintenance on my T1 engines, what kind of maintenance schedule would I be looking at for the above, and what kind of oil would you recommend?

Sorry for all the Q's but totally new to Type 4!

Thanks guys

Ohhh nasty things them 103s, you need to get rid of them for some nice 2Ltr ones that I have ready to swap ya ;)

Seriously tho sounds a good spec to me, you have it all there to make some serious power, providing the cam is right.
My 2Ltr when in its 1st incarnation had the same kit as u have (exhaust, carbs, valves) and was kicking out 130 bhp according to the rolling road. tons and tons of torque. so expect more than that.
I dont think there is a lot of difference from T1 building that springs to mind anyways.

You will enjoy it. :D

I think that you would do alright by the 103's , but only if everything is working together in harmony . By that I mean that you don't under- or over- cam the engine , or go overboard with the carbs , or whatever . The whole key to building a good engine is make sure that you have all the information you can get your hands on , and plan out the engine down to the last detail . The more work you do beforehand will save you alot of headaches later . Axl .
