Is that GR266 cam very different from the Kent 266? I had the Kent one in my 1330 van and while it was pretty tame down low with a fair mid range torque, it was nothing fantastic and ran out of puff all to quickly as the rpm went higher. I think the old Wade cam I had in my 1310 S was much more fun.

Well $1000 in parts and machining plus labour costs of stripping it down, cleaning, reassembly and possibly an engine dyno to sort out any starting and tuning issues.
Hopefully a mechanic can quote what the labour costs would be but I'll guess 2-3k for the whole thing, drop off to pick up.

You need to take in too account bearings, water pump oil pumo gaskets etc. There is another $500....

Kev You have been around Minis for a very long time, and you are well known and respected for your knowledge about all things Mini, So What do you think, is GR on the mark or not

I applaud GR for his work on small bore 998s and 1098s. They have been ignored by all and sundry for years because we all wanted a 1275. Sadly, those are now getting rarer and more expensive.

I've said it before- my 1220cc road Mini (with a near stock 940 head on it) back in 1968 did mid 16s 1/4 miles, it went a lot harder than with its same cam, head and twin HS4 carbs then put onto a new 1275 short motor.
I am not surprised at the HP and torque figures GR is getting from a 1220 now.

I disagree. Graham is not the only one developing small bore engines in Australia, he is the only one that advertises it on a mini forum though. The rest of us just get on with it.

Both Link Automotive and Matt the Mini man, have developed and offer performance small bore motors for a long time now, NMP built & sold them as well, and I believe Mini & Moke world offer them too. And I build them as well, the last 2 I did got good HP results without huge modifications, and the worn out 1100 in my van goes harder than most "performance" 1275s. Its not hard to make a small bore go well, hell Henry Draper competed at Targa Tasmania for 12 years in a 998 powered mini that bet every other mini down there, using 1.5 roller rockers that was said would never work.

And 1275s are not that rare, you just need to know where to look.

Merry Christmas.

There you go guys. Why do we bother with 1275s?

My current 1140 although not as much power as my previous 1310 is a hell of alot more fun too drive. The 1100 revs harder than the 1275 ever did.. a boy does it sound good at 7000rpm....

Not a great idea revving an 1100 crank up at those levels. they don't handle high revs very well....

(The Doc now comes along and tells us how many cracks his new 1100 crank had after he had been revving the guts out of it way back when )

I find this thread amusing,

End of the day buy and build what you can afford,

1275's have always been the top shelf motor, but really small ones can be built and repaired cheaper,

Nothing wrong with a std 1100 either they punch along, even a well loved 998 is good, Jesus I even have an 850 40thou over balanced and it hammers

Its like a Cooper S some think they are the pinnacle of Mini's other like original unique cars, less faked and rarer today then a Cooper S


In summary, its all ego's


Monte

An interesting take - but I agree in most part, and I'm not ashamed of that. There is something very cool about having a fast mini ,and then being able to say it's 'just' an 1100. Hell, that's half the fun about minis - they were designed to be cheap and practical, but they are now fun and fast. There is something inherently intriguing about using the wrong tool for the job.

Commenting from across the Big Pond...if I was in Australia I would love to try GR's build up of a 1098...since that is what is in ROO. However, I'm here with no local talent having experience working up the small bores...and I happen to have a good 20 over 1275 and a 1275 auto block (cost $35) on the shelf.

So I'm building a 1293...

Had a ride in town with GR's son Matt with the 998 worked over...went very well indeed, though an older build. Went for an evening ride with GR in the worked 1275...most racers would like that kind of power availability.

Maybe after the 1098 is retired from the OZ Van I can put together a project to replicate as closely as possible what GR is doing in OZ.
