    the downdraft shape of the port and therefore angled manifold face makes the port look bigger than it really is its actually 34mm and feeds a 37mm valve so the port is now almost 92 % of the valve dia, although it does taper down smaller as you get closer to the valve

    Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

    no more progress as such, i've been searching more camshaft option most options involve lots of cash which i dont have,

    i talked to cat cams earlier but when we got into 4 figure sums it ruled them out the equation, the cams themselves are a reasonable price compaired to schrick ones its just all the other stuff to go with them that really hurts

    cheapest is obviously use what i have and deffo be stuck at about 250bhp and have a major problem with too much compression

    reprofiling is the next cheapest option, but thats going to leave me short on lift and timing particulary if they keep the valve acceration down to avoid risking flicking a shim out.

    next option is to buy 1 schrick cam and use the group N inlet in the exhaust, the question is whether to err on the side of caution with the 284 which wouldnt flick a shim or the 292 which is slightly less safe,

    although its a faff to do i can convert to top hat shim for about £300, if i do that theres deffo no money for schrick cams,

    the way im heading now is to convert the shim type and get cams reprofiled, with top hat shims kent can be agressive as they like on the valve acceration so i can probably get decent lift and timing, nothing like as much as with either the cat or schrick cams but its should give reasonable power and no danger of a topend blow up

    decisions decisions.......................

    by any chance would VW or similar cars be the same? Some of the M42/44 guys use VW buckets AFAIK.

    i dunno if vw buckets are the same size but i do know they have the same shim arrangement, i.e the shim sits in the top of the bucket, which is what im trying to get away from

    Some guys use Volvo shims as they are cheaper than BMW you would have to dig through s14.net to find the info, and if you look on ebay.com there are a few sets of the supertech sim under bucket sets, also a Finnish guy done some work replacing the rubber mounting blocks with alloy so you can blend the ports to the throttle bodies and found a few more ponies

    yes i think i've used volvo shims before, i've also got a set of e36 buckets and shims which are lighter, i've since given thoughts to using alloy to replace the throttle body rubbers but right now have a more pressing problem in that i hit a waterway when opening up the rest of the head to match the high flowing port so i now need to find another head

    Bad news i guess its probably cheaper to get another than to get it fixed? Julian Godfrey fixed my mates yb head that was smashed by a valve dropping its head on the motorway but it all comes down to £££ at the end of the day, his was £3k for the headwork so it was worth him getting it fixed!

    maybe we actually broke through in 3 places! two went in to an area of the head that can easily be repaired/filled and i knew there was a chance of it happening but wasnt overly worried, the waterway hole was a real bummer though because its going to be dammed hard to get a tig to it and it means that port will have to stay smaller then the rest.

    will Jed do it for you? or are you going to bite the bucket and buy yourself a new christamas present?

    Sorry to hear about the head being scrapped, but sure the next one will be even better!

    I just found some very good information about head porting etc for this engine here: http://www.metricmechanic.com/pdfs/m...ne-booklet.pdf

    It may come in handy for you later on, port dimensions and flow graphs are all in there

    Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

    thanks jason, already got it saved!

    they do have one or two strange ideas though, like replacing a duplex timing chain with simplex on a full race engine

    maybe it was a one off but the port that broke through wouldnt of gone out the the bigger sizes the metric mechanics lot say

    the whole thing has ground to a serious halt, heads are easy to find if you want the rest of an engine attached which i cant afford, several people have told me they have heads but no ones actually coming through with the goods, the big nasty swine flu has cut me down, so i havnt worked for over a week, and willl of cost me a couple of K in lost income with lost overtime and productivity bonuses, fardon still havnt dont my crank, with a shortage of time and cash i might just chuck the towel in for now and wait until i can afford to build the motor i want to

    Get us a couple of pics of where you've broke thru Gra, our tig sets have very small angled heads so we can get in and out of pipes so we may be able to repair it for you, wont cost you anything either

    This question has probably been asked already but:

    Is it possible to fit an S14 engine into a Mk2 Escort? I got a rally prepped shell and am thinking about engines.

    anythings possible as they say, although the s14 having a front well to the sump will make life difficult as will the fact the engine is canted over 30 degrees leaving little room for an exhaust in an escort,

    its also an expensive engine to tune, in this instance a duratec would make a much better choice

    Even the flu could not stop you getting to Manchester to get the heads. Good find. Great to see that the project is back on.

    M42 use 35mm buckets (and there are shim under options - I have Eurospec buckets for my M42). Supertech have buckets for S14s (link).

    Also Graham have you seen pics of the chopped up S14 head on S14power.com (UweM3)? These could be useful.

    Lovely bit of kit Graham, are you missing many parts now to build the engine or is it all porting and machining now?
