supposed to be co-driving the SD1 sled
and isnt mini's doin manfield day before?

tl;dr

what does the oil do? i woulda thought is would protect?!Q?!

big slide hammer.
this. if you dont care about wheel nut threads you can put a bar/chain arrangement on those. chances are they will come out easily anyway
or a big effin Agle iron
good thing the reVenger is 4 stud, two holes for studs & use nuts to bolt on third hole for puller in center, agree 5stud be PITA for similar method

as for volume (dont think it's been covered yet)
dontcha need the same volume of air in the plenum as the capacity of your motor? (or enuff to fill 2x cylinder at any one time ie half) I can never remember
edit : some copy/pasta from some very knowledgable guys I am allowed to hang around
http://bbs.scoobynet.com/projects-40/420866-intake-manifold-more-top-end-power.htmlI stumbled upon this thread where Andy F is developing his intake manifold. Interesting discussion on the plenum size in particular. Bigger is better due to induction overlap between cylinders on the boxer 4. I hadnt considered this before
Unfortunately the thread turns political, but we know what it ends up looking like
Main points were pairing cylinders 1,2 and 3,4 for induction cycle separation. Larger Tb. And also having a plenum big enough for more than one cylinder to draw air from.

great read!!!!!!!!!!!from what i understand is that you want a plenium big enough for two cylinders worth of air. please correct me if i am wrong as i am going to be doing a cutom intake at this stage for something a little different and to help the piping to go over the alternator easily.
Is there a great deal of perfomance gains in dual pleniums considering cars like gobstopper only has single plenium ( not that i am going to do dual plenium )
what difference does the length and width of the runners have?
----------------
Dual plenums isnt necessary, you might get slightly better throttle response from having two throttle bodies, but the extra effort doesnt reap any real rewards from what ive seenRAC showed good gains from increasing plenum size from the v3/4 to v1/2 manifolds. V1/2 manifolds typically require a lot of honing out of the runners as the casting is poor. EJ25 manifolds are much tidyier inside and have the sameish size plenum, so prob best option
runner size influences gas speed and harmonics, it's all a trade off. long runners for low rpm power but less high rpm power, short runners for the opposite
large diameter to flow more gas but loose air speed and therefore torque, smaller diameter to keep air speed up but cause a resitriction at high flow rates limiting power.
in your situation there's little issue in starting off with a v3/4 manifold, get tuned and running, then look at switching to a manifold with a bigger plenum. Retune costs will be negligible as usually only fuelling needs to be slightly tweaked

half a hacksaw blade in a saws-all works wonders... (like a mechanical chisel but BETTER)

super charger off a dozer or something!
-
wicked - ya gunna get it hot dipped?
they charge for drilling holes ya know so put as many as ya can in everywhere to let the fluid out

Mate i know runs v8 Hillman imp with a Renault gearbox iirc

there is slipway Auto-X on sunday - meet windmill carpark around 9...
gate is locked after all enter, may be charge for vehicle not participating

1st dont underestimate the drums
2nd good planning for upgrading
3rd the cert guys will runs some basic test like stopping distance and fade (or heated stops) to ensure upgrade is indeed just that
4th proper pads and fluid can over come this from the start...
5 shouldn't be too difficult.. but I have nfi as I never done it before so all of the above might as well be ignored unless confirmed buy real mechanics... (or a chosen boe)

try keltik (pm)

i'll have a trawl later - probably in Fahrenheit or something fittingly oldschool

the oven trick regally does work on some lights I know the Subaru USDM guys do it all the time - it wasnt a joke...

records "may" exist of that wof tag... on hard file locally

awesome stuff dude - no stickies around here?

dats it yes she couldnt sell it whole

what was that DBdrag racer seirrer called? red - has cossie 2l in it

wtf is a KE2x ~ toyota?
best ask yerself - buggered if i know - hard enuff draggin him out to see a car/make offer - dont wanna do it twice..
running no headunit in car, whos done it?
