Well it's time to present my project.

I have a '82 998 mini who was fully restored six years ago. the car was almost original with a few simple modifications.
i fit a maniflow 1.75" side exit lcb twin Su Hs2 with ram pipes,a simple polish 12g202 double springs and a 45D aldon red,lumenition coil and silicone 8mm leads and a ngk B9EG
spark plugs,and it rev until 6200rpm.

now i'm start building a fast road 998 and i'm looking for "some more power".

the "spec" will be someting like this:

-Close ratio gearbox (3.44 or 3.76 FD not decide yet)
-S/C drop gears --------------- I've fond ones here in Portugal...lucky i guess
-A block with cut out's to fit a 12g940 33/29
-A+ flat top +0.40 press fit (Was 998 Std press fit pistons?
-A+ press fit conrod ligthened and polished (575g)
-A series crankshaft
-Lightened Vernier
-45D Aldon Red
-Weber DCOE 40
-Maniflow 1.75" side exit exhaust system
-Maniflow Lcb
-Lightened flywheel and pressure plate
-Orange Clutch Diaphragm
-Uprated clutch plate
-Kent cam 295 scatter patern
-Kent cam ligthened follower set
-Facet Fast road fuel pump Kit
-Facet fuel pressure regulator
-.............
-.............
-.............

now some pic's

Nice existing spec, you look like you're handy with a grinder too!

How much bhp are you going for? What hp is your current setup at?

thanks!we have to do when we have no chance to buy one made by professionals.

honestly don't know maybe 70bhp??, I think it depends very much on the head to use i hope i can find one well prepared!
the current setup i don't know because I don't have access any rolling road .

Do you allready have a set of S/C 998 dropears?

They are rare as hens teeth, thought...

Looks like it's getting a verr high reving little beast with that cam

Jan

not yet,hope i can find ones

nice project mate

I wouldnt use a 295 scatter on a 998 mate, the highest duration cam you want in a 998 is a 276, dont forget a lower duration cam in a 1275 may be more lumpy in a 998, but thumbs up with the build my 998 is quite well tuned with 70bhp.

Hi

thanks for the advice! i have a friend who built up a 998 like the spec of my engine but with a 286 kent cam and that small bore runs like the "beep-beep"
that car is a really road runner and in most cases can ashamed a 1300 lightly tuned!and he told me,if i were you i put that 295.now i'm confused.

once again thanks for the advice!

Cheers

A 295 scatter will make bags of power mate no question, but with the expense of driveability, by this I mean your power band will be very limited and high up the rev range. This means that your 998 will be very unresponsive until you hit about 4k by which time you only have 1.5k to play with before you have to change gear. The advantage of a metro cam, sw5 cam and 276 cam is that they are roughly the sort of duration that gives a good ammount of lift and power in a 998 that is very useable round town and with a much greater power band and a desirable straight torque curve if this makes sense.

i only go to tihs type of cams because the mini is not my daily car,i use it only for 2/3 days/week.just to take a ride with my friends at night or trackday's or a sunday morning to take a coffe and take a hill climb etc etc, its the car who takes my stress away, press the "go pedal" and...catch the 998...if you can...

I that case go for it then mate, it should be interesting to see!

real nice job on the rods, spent abit of time dong them I bet.

I will keep the post updated, for the rods it takes about one,two each...when the job are all done, it's time to weight one by one and try to keep them with the same weight.

it's really nice to have so many reply's and see how interesting is a built of a small bore engine.i'm just a curious who loves minis and DIY.

so if i upset you guys with more and more questions about how it works and how is the best option don't forget Small Bore Power addicted and if i mistake write someting
don't mind, i'm portuguese and don't speak/write or understand you at the "first shoot" so i have to translate some parts.

Best Regards

Looks like a good project, keep it up, nice country portugal, where abouts are you? I like Alvor and around there lol.

I'm from Sintra (near Lisbon).

one of the first run with one hif38,now i have the weber dcoe 40 and its more racer than ever

Congratulations!! Nice sound! How much does it rev?
I love how the revs just continue to go up

Well done!

Cheers,
Jan

I Love SC Drops

That sounds awesome, i love the straight cut drop gear noise!, great job.

TKS!

i love them too.later i'll put a new video in the same road but with the weber.now i have great exhaust sound,great gear noise and great intake sound too.
and some mates who don't belive that it's a 1030 running..only rev until 6k.but i hope that 296SC put my revy upwards until 8k.

unfortunly i can't put some more pic's of the job done because my status here in the forum don't let me dowload more:(

i'll try delete all my photos and upgrade.

Cheers

that sounds amazing!!!

try using this website for hosting you pictures:

Hi mate, Great work on that engine as i told you.
And for all the guys from the forum, believe that is far much better when we are seeing it rev all the way up...
Not bad at all for a 1ºst try building an engine
The sound is so sexy!! love the drops and the webber

keep it up my friend, hope i see it again friday.

Abraço

Hi there!!

that 1030 still running.now have 2500km done with one single but big problem...a broken diff .
but one bad thing turns to a very good upgrade(SCCR).still have that advance curve on the dizzy to modify.

considered megajolt ignition? especially if your putting in the 295Scatter cam..
very nice build im doing something very similar atm

wow, wow and wow i love the sound of your carnice work.

Nice nice nice & 10" GBs

Did you take any pictures of them fitted but without the arches?

yes i have,but can't put more photos here

think it's about the status here in the forum.

If you make an account with www.photobucket.com (it's free by the way) you can load your pictures up to photobucket and link them into your project thread. Dead easy. If you need help just post on here or pm me and i'll help you.

Andrew

yes i do.i when my mk2 bodyshell were done i will open the engine again,put a swiftune ultralight flywheel and backplate (everithing balanced again) and then install one megajolt .

and a another 12g950 but 35/29 instead 33.if i could bought one CST fast road or race spec or another of the same range i think that 1030 will be great!

already smash 2 1300 one stock A+ and a 1275GT stage 1 kit hif44.

very nice i like this a lot, i want your wheels.
