upgrade to a 318is

[Dan318-is]

interesting!

why new wheels? what ya got in mind?

and what chip?

personally i would do all your performance and maintenance mods an then get a remap youl unleash way more power

I could never sell those wheels!

[Jamesb318is]

These babies



prefer something with loads of dish and in a smaller size for handling. Still deciding though, and would prob keep mine for winter

I'm gonna try a viper chip, i know you had a bad experience but i'll see how it goes!

Anyway - i'm stealing the thread - back on topic!

[Dan318-is]

yep

im also dooing a mini m42 project but nothing on tims size or scale

jsut a little 1.9 conversion with m44 rebuilt bottom end, reground cams, hopefully megasquirt (with the help of my EMS lecturer) and eventually dbilas

i also have acces to gas flowing facilities for the head

but first thigns first i need suspension n brakes upgrades on my pile of poop so it wont be started until at least may unliek Tims who is started already

[dark_sounds]

wheels that sexeh,,, its all good.

yeah i was messing about with search function looking for a chip for the IS general consenses is that theres nothing availible thats worth using.

i understand theres no useful induction kit, though what about a replacement K&N air filter eliment? havnt explored the engine much,,,, but cant you put in a air filter and drill the air box?? if it has one?? this gives a similar effect and sound to an induction kit... thats what alot of poeple do with the mk2/3 polos iirc

[Dan318-is]

IS dont respond well to kits of that type, sal has confirmed this on a dyno i believe

induction kits dont do a lot without shields anyway

a big bore throttle body is a much better option!

[dark_sounds]

what big bore thottle body can you use and goes onto the IS easily? how much is the cost roughly (cost of parts and labour seperate)

[tim_s]

ha james, don't think the thread has much topic anymore does it? thought talking about my golf was more offtopics!!!

fair enough on the diff thing, i'm with dan though, its a good modification.
i've always been a bit uncertain about the throttle body, i'm sure it'll help get more air in, but i'd have thought that goin bigger you're likely to run the car even leaner than stock at WOT as i think the injection will be running open loop (ignoring sensor input like afm) and sucking in more air than it expects.

those wheels look great for an e30, the right kinda style for the era, and a huuge dish. perfect! how wide are they, how big and how much!

as for viper chip, mine's great for me. a really noticeable improvement, it goes a good bit better. uses possibly a bit more fuel in day to day driving, no noticeable difference on the motorway though. might be getting some 'before' r/r power runs done before i put the new engine in, may get one with and without the chip done.

dan: i'm re-boring mate to fit bigger pistons (then honing obv!).

dark_sounds - k+n filter element if you want, but wouldn't bother with induction kits or whatever, tried one did very little for me and sounded naff, was going to use some samco and mount it right down the front to draw in some cold air, but sold it cos it was crap, the 318is doesn't have an impressive enough induction to make them worth it. again, drill the airbox, but you'll fuck up a well-designed air box setup just to get some induction noise.


i've been playing with a mate's scirocco today, we're mating up a 38/38 twin carb to it. sounds mental, proper old school car engineering stuff that was
mm carbs.
my bm feels so slow, went in my mate's audi s2 today. big boring fast capable back-to-front porsche thing. very very fast, nearly as fast as my mate's sierra cosworth. cars like that are unreal, power delivery so much more exhillerating than s50s.
anyway, the mates of mine who i was helping today are up for helping mate throttle bodies to mine, so maybe that will happen after all. they have access to cnc'ing facilities etc, so is sounding good!

[Jamesb318is]

The zone shop does them
http://www.xsperformance.co.uk/e30zone/ ... f81c2a3c00

[Dan318-is]

the throttle body does make a difference, at high revs. low down i noticed nothing. but above 4.5 - 6.5 K the car does pull a bit better

im with tim on the induction thing too; no drilling no cones, just use a filter element from KnN until you can afford TBs

Tim that scirocco sounds like a beast!

tim without being rude, how much u paying for a rebore?

i think i just had some bad luck with the viper chip, im very temtped to try again but i would rather spend my money on HnR chassis upgrades and brakes then just get a remap when the 1.9 is done

or jsut get megasquirt

tim what you doing for management on the 2.1 any more thoughts?

[Jamesb318is]

anyway, the mates of mine who i was helping today are up for helping mate throttle bodies to mine, so maybe that will happen after all. they have access to cnc'ing facilities etc, so is sounding good!

Go on the throttle bodies! - always wanted a set, i will be watching/waiting with baited breath!

those wheels look great for an e30, the right kinda style for the era, and a huuge dish. perfect! how wide are they, how big and how much!

They are from a UK firm www.imagewheels.co.uk they made Bootymans wheels, and my uncles got some on his kit car. They can make whatever size/width you want! so i'd probably go 16x7.5 on the front and 16x9/9.5 on the rear. That would make them over a grand though, but your car would stand out a mile!

And as for the BBTB, i'm willing to give it a go, and wouldnt the chip help with the increased top end fueling?

[Dan318-is]

i cant comment on the chip as it didnt help me at all!

[tim_s]

james, yeah bbtb will prolly compliment the chip nicely. out the box, m42s are conservatively mapped to help fuel economy and not performance, so bbtb is pissing in the wind really, but when the AFR is lowered a bit using a chip, its a different story.

rebore i haven't bothered to ask mates where to take it yet. prolly cost about Ԛ£100 from past experience, have used an engineering firm in bristol before, nice chap but a bit pricey. a mate of mine is r/r his motor at circuit motors at castle combe on friday, i'm prolly gonna come along for the craic and have a chat to them about some stuff. pistons haven't arrived yet either though. need to get all engine components balanced too, and want some newer bmw 'cracked' rods too.

management on the 2.1 conversion is a bit of a sore point. basically its gonna cost a fortune and is depressing. i wanted to keep motronic, going to MAF mb as i reckon the AFM will prolly be maxed out, then get it rolling road remapped. a mate of mine is on about me getting something like emerald and mapping it for me though. i don't want to go to standalone as its a daily driver! i want nice part throttle behaviour and reasonable fuel economy!
motronic is decent and reliable, and although the standard is stuff might not be upto the power i'm gonna get, i reckon i can up some of it to cope. my mates are strongly against my ideas on the fuelling though, think i'm being a pussy, basically. this is an area i'm not brilliant at. i understand motronic very well, but am not the best at knowing about its limits etc.

will prolly build the car then tackle the fuel system afterwards. this is not considered conventionally wise though mate! generally ppl say make sure the fuelling is sorted before messing about with engine stuff.

[Dan318-is]

theres a place that will rebore your engien for 40 quid near me. they charge a tenner a cylinder, his name is Roland Alsop. Let me know how much you pay will be interesting

from what year onwards were the cracked rods used? are m/s50 ones a no go? what about more wilder ones like the ones in a m60 they no good?

emerald website is fookin useful, like you i wont mine as a daily so standalone would be maybe a waste of money. having said that emerald csot about 800 quid were as you can get megasquirt for about 350-400 an have something which is well coveredd and standalone?

[Demlotcrew]

I cant see why a stand alone cant be used on a daily driving car?

Andrew

[Dan318-is]

i spose it can really, just money aint it!! if tims spending all this money on the rest of the engine an has a budget fitting a 800 quid piece of kit in at the end could be a struggle?

although this iant the case with megasquirt i guess?

[tim_s]

shit, Ԛ£40s good! a tenner a cylinder! wow! you had any experience of them? you in surrey yeah? i'll see what it costs down here, but might be worth considering. cheers.

emerald's been going for a long time and is well regarded, but commands a premium - you have to bear in mind you'l get second to none support and setup though. and it used to be way more expensive.
i'm not going for megasquirt. i know MS makes sense, its just that making a car that's not suitable for everyday use would be missing the point of this exercise, and i'm not 100% on MS's reliability.

i really want to keep motronic, there's nothing wrong with it!

[tim_s]

andrew, i'm sure a standalone sertup can be used on a daily. its jsut for me drivability first, performance second. end of. this car's used for running me around, its never gonna be the fastest car on the planet, i want reasonable fuel economy and good drivability. most standalone setups and ppl who map them are tailored towards performance first, drivability second.

[tim_s]

oh and andrew, i still want those cams and carriers off you dude! wanna pm me an all-in price? try www.interparcel.co.uk or parcel2go.com for postage mb.

[Dan318-is]

just found his number : 01276 858073

without being harsh, be very polite, hes not the friendliest of old men! but a fucking good workman has been recommended to me buy everyone around here

thats a good point about emerlad. but support on here for M/s woudnt b to bad! i think both have there positives and negatives

m52/4 pistons, r they the right dimensions 4 u?

[tim_s]

you're a champ fella! sounds like a funny bloke mind! im a fussy sod so maybe not the best idea, plus i want to make sure the bores are perfect - the standard to which the bores are done will influence the life of the engine.

i reckon MS would be a great project and definitely the best performance per Ԛ£Ã”šÃ‚£, its me that's being awquard really. i'm just going for maximum reliability over everything else.
MS is supposed to be awesome. if you get around to it, do it separately from your engine project, as it will be too tricky at the same time. plus get in contact with that chap i mentioned earlier in the thread, as he's done it to an e30 m42 already.

oh and i meant m54/2 rods, not the pistons. the pistons are no good for me.

[Dan318-is]

i meant rods not pistons sorry for generalization

hes a good bloke he just hates good customers; i thorougly recommend him

im using Ms i think when im done purely cos of the cost, although it will be harder i guess

need 2 source a laptop also

[tim_s]

ah sounds promising mate! definitely an option!

I'm getting some whacky ideas now injection-wise, but makes sense in my head somehow.
jsut had a chat with a mate cos this thread got me thinking a bit.

latest is i'm thinking going to go to e36 m42 318is injection to give me knock sensors and lambda. this would be the bare minimum. would want to convert to MAF too, maybe using a piggyback, maybe just through remapping.
mb i'll even go to m44 obd II with MAF and live mapping capabilities. don't know enough about all of this, know i'll need the EWS module for m44 conversion, but this might give the most potential.

don't want to keep the primative e30 system when there's much more advanced systems out there designed for the same engine.

[Dan318-is]

how would you install knock and lambda sensors into an m42 block?

interesting theries here guys!

[tim_s]

dunno what the knock sensor looks like yet but as there's one on the e36, can't see why I can't have one on the e30 if I've got e36 injection sys, ecu etc.

[Dan318-is]

i spose the lambda wouldnt be a problem, it would just be a case of choosing a sensible place for the knock would it not?

OBD and EWS?

i lack knowledge in the e36 department please explain?

iv heard of m30 AFMs being used

[tim_s]

mb an M30 AFM might be an idea... mmm.
OBD - on board diagnostics

ODB 2 - post 95 cars (m44) have a new version of motronic (OBD II) that gives a load more info on the car etc.
EWS is the security stuff

as for knock sensors, both e36 m42 and m44 had it.

dan, i don't know that much about all this btw, never had to look into it in any detail before, so don't take all this as gospel!

[Dan318-is]

m42 did not have knock sensors no, this was one of the "major" upgrades of the m44 engines i think; that they included one

that on board stuff sounds rather interesting but messing around with ignition barrels finding new keys n stuff is a large hastle for a fuel system overhaul aint it?

i take it you can install OBD without EWS? if you can than that sounds like a plan if you can find a place for the knock sensor

could youl not drill a hole in the block or something?

[tim_s]

just edited my above post mate, but obv you missed it. e36 m42 does have knock sensors, and same block as e30.
so knock sensors are possible definitely.

[tim_s]

oh and you don't have to actually use the new key/barrel with obd2, just tape it up and hide it somewhere.

[Dan318-is]

lol i like the sound of the barrell one thats more my "basic" engineering lol

so e36 m42 lumps had knock sensors but e30 m42 blocks didnt?

interesting!!

so on the e30 m42 lump is there not a location for the sensor?

[tim_s]

the block should be fine for the knock sensors. problem is, from the etk i can't see where they actually go! all i know is it has the same block, and the knock sensors are under ' block attached parts'

[Dan318-is]

the e36 swap certianly sounds like an original idea my man.

how much do you rekon all that is going to cost though?

also, engine loom would be a bitch would it not?

[tim_s]

it wouldn't cost much, beginning to wonder if it will give much benefit though.
it is original, might be a complete waste of time though!

m44 conversion might be more worthwhile, its harder though.

[Dan318-is]

both sound like interesting ideas. i certainly wouldnt have a broad enough knowledge to take on either; however if its done it would be interesting to see the result! problem is do you know of anyone who has done this? like you say if the early m42 e36 block and enigne is basically the same, the ecu cant be that different? so i dont see where the gains woud be?

are you sure you can get chips remapped to accept maf? i thought that you had to buy piggyback ones?

what do you mean wire the temp sensor manually, exactly?

[tim_s]

its not all about gains in power fella, i'm thinking about getting the car fuelled as well as possible. knock sensors are a really good idea on any engine, especially if like me you're on about running a high compression ratio. basically not running knock sensors, having a completely different engine in the car and stock injection, the consensus is i'm setting myself up for a fall.
lambda is only any use for part throttle and can be a pain in the arse, but ultimately keeps emissions down and fuel economy up.
mate, whats the name of the bmw electrical program that has all the wiring diagrams on it? do you have wiring daigs etc? I have some info from an e36 bentley, which seems to me to suggests all i should need to do is swap the ecu over, add knock sensors and wire to the appropriate pin (which i know now) on the ecu. it looks like the the connector for the ecu is correct.
