Pre A+ 1330 engine. Will be turbo'd.
Turbo Mini Forums

Hi guys.

I have had a search around and just wanted to ask again as i could not find to much information. Sorry if i missed a good thread!

I have been offered the following engine.

1330 engine pre A+
+060 pistons
kent 286 cam
11stud cooper head
ARP bolt kit
New duplex timing chain
New oil pump
New Alden race dizzi
Rod change straight cut gear box with straight cut drop gears
3.44 diff

With a change of pistons/cam and some head work is there anything else I should worry about going for a pre A+?

I have a megajolt setup (i know the dizzy differs), a gt17 and a mirage mani.

I read about the hole above the center main but I doubt this will cause me any issues aiming for around 130-150bhp not to high revving.

EDIT:have now purchased to turbo.

Depends on the price.

But fundamentally there is no reason why you shouldn't turbo a pre a plus engine.

It is a very good price :). A few pictures.

you could get those pistons dished out a bit.

Its sitting in the shed now, so no going back!

Nick on here has used the 21253's dished out to 11cc

I will try to avoid taking material out of the pistons. I hope there is enough room in the head.

Started stripping it down today added a few pictures in my build. I did think about not stripping the bottom end. I was right to though with a hand tight gear box layshaft nut.

I'm going to keep all my questions in here on this engine. Some bits i've found during strip down...

It seems to me its more A+ than pre. The gearbox is A+ with a 16mm shaft and 3 bolts. Good news.
EDIT: Scrap that, wrong shaft its 14mm Pre A gearset in an A+ box with A+ drops.





A+ casing.



Innocenti/1300gt rods, light and strong.



Although i have a slight issue here... Would it be acceptable to smooth the high areas, or is it scrap?



The laygear is stamped as follows, 22a1737 on minispares website it should be 22a1737'A' for A plus but after a bit of digging i found this information...

"The laygear has the pre A plus number stamped into it but is in fact an early a plus laygear...apparently when the first a plus boxes came out they had a bit of a mix and match going on...So it needs the pre a plus shaft but works with the a plus gears!! how confused am I now!!"

I'm confused to, layshaft seems ok for wear so just new bearings needed.



I think i need a floating bush.

Its quite floppy on the crank and has been ground away a bit.

On a second look, after checking bearings, laygear itself looks worn out :(.

Stress relieved the box.



Blasted it to.



What do you think of this synchro? Its 1st so i was think just use it.

Baulk ring definitely needs changing.

Edit: its 4th... so better change it. Not re built a box before, steep learning curve!

Take the baulk ring off and inspect the cone. Had one of these wear in an early close ratio a plus gearbox in the past. I had to change for new as it crunched into fourth. A new baulk ring helped for about 100 miles!
