Can't sleep, so I decided to start my own projekt thread.
My Mini needs some rust and crash repairs - so thats a good time to add some performance too.
As I went to the SRR08 the weekend before, I crashed into a Golf (was tired after 2-3 hours of traffic jam).
No major damage, but needs to be pulled out plus some new paint.
And the rear end has become rusty the last 3 years - and needs a replacement.
Luckily the only panel in need of replacement (it's a '84!).

Now the part I like the most: my funny iron-puzzle
I'm currently having a 1275 50HP SPI engine, with 'Stage1' and HIF44.
It runs well and economical - but I'm in need of a bit more steam!
And - as I'm a rather poor student - it needs to be 'no-budget performance'.
Which means: no extraordinary expensive high-tech parts and doing everything possible by myself.
The base for the new engine is a 1275 RSP Cooper engine.
Got it for almost free - but needs a rebore and new bearings + pistons.
I don't want to go for a 1380. My aim is something unusual.
I'm currently searching for +.030 pistons + rings. They are quite rare nowadays
but will give 1300 (or 1301) cc - that's the biggest legal bore I can go.
In Germany taxes are based on the engine's cc, x€ per 100cc. I'm paying for 1275cc - so I'm "allowed" to go up to 1300cc.
1310+cc will go to the next 100cc step in taxes and cost a little more... But the thing is: I just want an exotic bore

The internals look very healthy, exept of the exploded piston which damaged the cylinder wal
Rolled radius A+ crank and good A+ rods.
Will be balanced and weighted. same with the flywheel (balancing together, of course).
The head I'm going to use is of an Innocenti B39, 36/29mm 11 stud.
I will try to port it myself. Thats why I have another - cracked - Innocenti head for practice
The good head cost me a bit - the other was for free.

Polished valves, 36mm in, 29mm ex. Swapped for something I forgott.
Maybe I'm going for 30mm ex - but due to the minor difference I'm not sure about it yet.
My (smal) budget will decide what to to

As mentioned, I have a smal budget.
So I'm not going to use high-tech aftermerket stuff like full roller rockers and the like.
An old Innocenti pressed steel rocker shaft must be sufficient (they'r stil WAY better than the sintered A+ *rubbish*).
Got it cheap as well (like 5puond).

And now the most desirable part of the engine:
The 1.5" Reece Fish carburetter. It's a rare early piece with the original cast Reece alloy manifold!
Pure retro porn! Expensive - but bought before becoming a student
As I couldn't find an original trumped I ordered a custom one.
Another reason for the custom trumped is that with the original it would have only be possible to fit a sock filter.
And I don't like sock filters... So my trumped has a big brim to support a K&N filter.
The second trumped is more like a stubstack to give more room for air inside the smal filter. I will see which one works the best.

The only thing I'm not sure about is the camshaft.
Either I go for a Swiftune SW5-07, try the experiment with the A+ 998 high compression cam (the one I have - would cost me nothing) or - I don't know.
MG Metro is another choice, or cooper 997. Or MD246, or MD266 (but opions are divided about MD266 over here).
Compression will be around 10:1 ish.
Plan 'B', if my budget is too smal for a new engine:
I'm having a complete set of new RSP Cooper (&co.) pistons.
If my budget should be too smal for a completely new engine, I will put them in the SPI engine and put the head on there.
That's my 'rescue plan'.
The engine needs to come out anyways,
I want to check the transfer gears and the gearbox needs a rebuild...

(But if anyone is in need of a swap (cooper for +.30) - PM me )
For my new engine I'm getting another A+ rodchange gearbox.
All I have to do is bring an 998 Cooper engine from Switzerland to Berlin.
(Would have ben gone to Berlin regardless of it - but it's a nice addition, isn't it?)
So thats the iron-puzzle I'm going to play with. I
t may take a while to report any progress here - but stay tuned!
Best regards,
Jan
