It's when I read this thread that I remember I have absolutely no idea what the hell you are going on about

Re: a very powerfull and troublesome bmw 316

im really struggling for motivation at the moment, the main problem is needing to spend some big chunks of money to take the project forward and i havnt got any

i did a bit on the intake side the other day rummaging around in a scrap bin i found these



bored a 14mm hole up the middle of them



mounted them at an angle and flycut a semi circle into them, and cut some holes in a strip of alloy plate



and got these! which still need welding together, once i've decided exactly what im doing with regards to filtration because thats going to effect the positioning of the outer injectors ( going to run the engine on 8 injectors)

Re: a very powerfull and troublesome bmw 316

ive also been thinking long and hard about the dry sump, dry sump pans for this engine are horribly horribly expensive, the cheapest i found was from america and that was still going to cost me £500,

in the end i choose to swap the big cast M3 lower sump section for a steel non M3 one and modify that, i dunno how well it will work, becuse dry sumppans normally have a channel right along there length, which i couldnt do unless i swapped to an all steel Bmw2002 sump, but i think i will be ok on that front as upper part of the M3 sump has a nice scraper plate built in and does a good job of putting the oil back in the well.

doing the job with in two halves with the sump bolted to its alloy upper part and a block i hoped to minimise distortion, it worked to a point, the sump did distort a bit but is flexable enough it will go back into shape when you bolt it up, i didnt do a bad job either if i say so my self, holding the finished artical upto the light i spoted 5 pin holes, migged them up and filled it with deagreaser and found just one more








after a really thourgh cleaning i painted the sump inside and out, not something i'd normally doo but i figured it would help prevent any possible future weapage, plus any tiny bits of weld splatter which may of been stuck in a joint somewhere are now permanantly sealed in and will never go up the oil pump, i hope :prey:




my only slight resovation with teh whole design is that it leaves a "wing" which will trap oil round left handers, on the one hand i think thats very bad news, on the other, the engine always did trap oil there before but cant trap as much now and the dry sump tank holds more oil than a normal sump, i might have to see if i can come up with something that i can bolt in to fill the void

Re: a very powerfull and troublesome bmw 316

lastly i went back to my ashley 3 piece manifold after getting the primaries to fit the head, i kinda lost any enthusiasm to finish it but finding i was getting stuck everywhere else on the project i dug deep,

first thing was to make a new "y" piece for branches 1+4 as i had to seperate them to get it round the steering,



basically with the primaries bolted to teh engine i just worked my way backwards, using some off cut bits of exhaust a bit cut from a new old stock astra back box and i bit from an RS2000 exhaust



and turned my ashley 3 piece into a 4 piece

top work keep at it, looking forward to seeing this out on track

Re: a very powerfull and troublesome bmw 316

Graham,

If you want to make a revision two sump using the ally M3 one, stick it in the post with a a dimensioned drawing and i will happily mod/weld it for you FOC.

Doesnt running 8 injectors put you in the big class mate.

only with forced induction, and im coming to play in the middle of the pack without one

Re: a very powerfull and troublesome bmw 316

Middle of the pack!! I hope that the class C cars will be higher up then that next year I know I want to get in to the 52s around Brands next year

Re: a very powerfull and troublesome bmw 316

a little progress,

having finished the exhaust manifold i pulled the short engine out, and put a std m3 piston on one of my nice new steel rods, piston pokes out the bore by 2.5mm, but my new accralittes when they get here will be 1.5mm shorter, so they shoukld end up 1mm out the top of the block which will work well with a std head gasket which is 1.75mm thick

Re: a very powerfull and troublesome bmw 316

Loving the build! cant wait to see the trumpets tiged with the standoffs ! Seriously impressive stuff! Everytime i look at the blue paint i think its going to be a stunner! Cant wait to see some more updates!

Re: a very powerfull and troublesome bmw 316

sadly no more progess except im now the proud owner of a very expensive new oil pump

Re: a very powerfull and troublesome bmw 316

Me too Graham, i think they charge by the kilo, cos the things are damn heavy too

I take it you are making the bracket etc yourself..

too tight/skint to do anything else my friend,

i might have an easier job of it though if i can have the loan of your dry sump bits

No worries, will try to pop up and see you next week so you can try my pace kit on yours.
