Twin cam 998 running
Turbo Mini Forums

well,,, i see no reason why you couldn`t turbo inject one of these "Little" things,,, this std one with a single SU carb & std mini dizzy just screams

I have noticed a whole lot of bollocks being bantered about as to the viability of twin cam small bore engines, & i`ve certainly had my fair share of people all around the world asking my advice after they had allready purchased conversion kits from other companys & am always happy to help out if & where i can,,, & it seems there was very little info avaliable for the small bore twinky punters at the time,,, well all that is in the past & i hope i`ve steered most of them in the right direction because this one is an absolute little ripper.

I`ve made 3 small bore twin cam engines myself now & i`m certainly going to throw a turbo onto one of them soon,,, well as soon as my 1510cc K1200 head-ed road engine is finished

This particular engine is a std, bare bones, 8V, on 998cc (taken out to .080 oversie) single carb & std dizzy,,, probably the very cheapest twin cam in the world, it cost me very very little to build,,, it`s probably the very slowest twin cam mini engine too, but hey,,, it`s a good cheap little run-around for me

But Wow it just loves to rev

Sounds Good.

I'm a bit behind you with mine. I might get the engine built next winter. then just need to prepare a car to fit it in.



I think Miniboo is near to running his.

Yeah i`ve been talking with miniboo all along , he`s getting there

I`m really starting to fall in love with this little donk & as most of you should know i`m very much more a fan of great big whopping big bore donks, but this one is just a sweet little screamer


& sorry about the crappoy video,,, it`s just off my phone camera

i`ll take another video with my helmet cam from in the car in a few weeks

Very good. I have plans somewhere amongst all my projects. I have a K100 head for instance.

I'd be interested to see what cutouts are neede on block and pistons.

wil_h,,, this one is only .080 oversize bore & have tiny reliefs the top of each cyl for the valves to clear,,, if you went for 120thou oversize (like another one i`ve made) then you don`t need these cuts,,, i`ve also built a 100thou oversize & moved the cyl head over so it has fly cuts in the top of the block but only for the inlets & they`re only tiny little ones that i did with my die-grinder,,, they just needed a whisker

& piston fly cuts are simply done to suit each engine build, i think we went 5mm deep in this engine, but it will depend on yout own engine, piston choice, deck height & position of bore centres etc as to where & how deep you need to go,,, but that all gets worked out on the "Dummy up" stage,,, its not hard & quite normal engineering practise for anyone worth their salt.

hee hee,,,i`m getting more comments about the evil laughter at the end of the vid than the about the engine itself

Shame I cannot see the vid from work :(

yeah Sproket, it`s just me being a dick running a small bore twinky donk on the ground,,, the camera phone sucks & looks like i`m doing it all in the dark,,, it`s crap really,,, i`ll get a better vid of it when it`s in the car

Cheers for info Matt. If I use the engine for the hilclimber I'm restricted to 1000cc, so standard bore and stroke, or 850 stroke and +120 (iirc).

But if I use it on the road car it'll be +120 on a 998 crank (easier and cheaper).

Either way it'll be turbo'd

good stuff matt

Team Racing

ok wil_h,,, i understand your reasoning,,, so my toughts there would be 1071 Sth African donk large journal with a slight sleave down or destroke a bit ,,, either way probably the strongest & revy-est way about it

& Jimster,,, not sure i`ve congratulated you on your beast yet,,, but still,,, very well done mate,,, the bench mark has been set

"""LazyGoodForNothingSmartArseKnowItAllBackYardMiniMechanic"""

Cheers Matt, I can see a few with the same power or more from others too soon

Team Racing

yeah so true mate,,, there are plenty being built with major potential

This little one has killed 2 birds with one stone-->I just needed a cheap little run around donk for my road mini,,, & it also served well for my build guide info purposes as soooo many people havn`t a clue how to build a small bore twinky

Ok, I`m off surfing Byron Bay, see you all next week
