another S50 swap! now TURBO

[bigpimpin]

Ahhh, those pics bring back fond(? ) memories !

Gaz, I have a 3.25:1 M3 LSD sitting in my garage. It locked up due to lack of oil but I think the actual LSD bitty is interchangeble between diffs. It doesn't look damaged when I took the rear cover off so I presume its that LSD bit thats buggered.

[ian332isport]

Gaz,

I've done your charts

If you let me have an email address, I'll send them over.

Ian.

[gazatron]

cheers ian i have pm`d you my email.

Yeh im BMW through and through so yeh it is jap wrongness, but it goes like stink dyno`d at 304 bhp and in a egg carton also 4x4!!

been down the unit tonight didnt really do to much except give the car a good coat of looking at. but i have got a few questions if any one is feeling knowledgeable.

what gear box set up have you guys used i.e cross memeber, selector rod etc.
ive gone with e36 crossmember, e36 shifting arm, e30 selector. and e36 shift lever. it all fits well but the shift lever sits slightly to the right in the
car rather than central just wondered befor i have a tinker?

[buster]

Hmm.strange actually as mine sits slightly to the right ( 6 speed ) .
It sat more to the right with the e30 gear lever but when i used the original evo one it put it more to centre,but like i said, still slightly to the right.
Do you want a picture ?

[gazatron]

yeh mate do a pic, it changes gear fine just 5th sits very close to the center console

doing some more tonight a few bits came today so ill put up some pics where im upto, going to finish the wiring to thanks to ian

[buster]

5th gear is ok on mine,not close to console.Infact in the extremes ,reverse and 5/6 th it seems centred.
Pics speak a 1000 words.

Natural/relaxed not in gear :





Reverse :



5th gear :



There you go,
cheers,
andy

[gazatron]

cheers mate, im going to have to play around with the linkage mine seems a bit more over than that, any sugestions any one?

i have a few questions with pics if thats ok guys?

lambda probes and reverse switch, right?



relays, mass meter plug and red eyelet and black eyelet, where do the eyelets go?



diagnostic plug, one black eyelet and two red ones one fatter than other where do these eyelets go?



expansion tank, the two smaller outlets near the cap, one goes to the rad, the other???



cheers people!

[old_skool]

expansion tank, the two smaller outlets near the cap, one goes to the rad, the other???

Vent pipe, goes down through the inner wing.

[gazatron]

ok thats easy solved, any one else got any sugestions for the others?

[gazatron]

i think i may have sussed them out now if any one can just tell me if this sounds right?

the pic of the two wires with the relays, the red one is the live for the fuse box not needed of the e30 one is in place. and the black one an earth?

the two red with the diagnostic plug fat n thin go to the bat + terminal on the bulkhead, and the black is an earth?

sorry to mider but want to get this right for obvious reasons, "whats that smoke!!!!!"

[jmc330i]

lambda probes and reverse switch, right?

Yup, reverse lead isnt needed as you use the E30 one.

relays, mass meter plug and red eyelet and black eyelet, where do the eyelets go?

Both are live - if you peel back the black sleeving you should see the wire is red. I think both connect in the fusebox (Im sure thats what Ive done). I removed the E30 fusebox live and used the E36 one as it looked neater.

[jmc330i]

diagnostic plug, one black eyelet and two red ones one fatter than other where do these eyelets go?

Black should be the earth, cant remember where I fixed it to the body - probably inner wing on drivers side (where the M20 coil was).
2 reds to the battery +ve terminal - smaller one can go to the smaller wire on the +ve terminal which is fused IIRC.

[jason90m]

lambda probes and reverse switch, right?

yep, lambda probes. also wanted to mention that they are numbered. #1 and #2 with the plastic yellow rings near connector. lambda probes are also numbered. #1 goes to cyl. 1-2-3 and #2 goes to 4-5-6. dont mix them up, car will not run correctly. cheers, jason

[e30Alex]

hey gaz, you based in southport by any chance?Alex

[MR_SAZ]

i just just my intake manifold lastnight....far out if only i saw this thread b4 hand.... i still may move it over before wielding up again... i dont want to lose BHP's...looking good guys!!!

[bigpimpin]

Yeah, what he said, I found out eventually !

[gazatron]

alrite guys sorry for the lack of posts not been doing too much on the car recently, its pritty much finished except for last few bits mainly waiting for the exhausts to be made on the 15th of may othwise it would be done!!

we have had it running in the car but with no exhaust, manifold back, its far too noisey to do anything with.... ill get some pics up. its getting painted this week so if not before it goes when its nice and shiney when it returns!

has any one uprated their calipers, thinking four or six pots, did you have to change the servo again from the audi one?

and any comments on a nice black to paint the car while its having a full hit?

[Jhonno]

what about one of the blacks from the e46/e60?!

Video of it running without manifolds? Where you getting them done?!

[gazatron]

yeh they are nice blacks but they scratch so easy, i dont think i have seen one without swirl mark scratches in it! the manifolds are on now and bolted up, a lad we know modified our original one, only took him a few hours or so over a couple of nights. but its still very loud and the lamda probes are just dangling there!

changing the subject slightly been offered a diff off a zm roadster (or coupe cant remember which one) cheap enough is it more the ratio that is needed over the 325 lsd thats on now, plus it has the cooling fins which look cool

[Jhonno]

worth getting for the backplate maybe.. Its a different style of LSD tho, but does fit

[Assault]

I've put a ZM roadster diff in ours but we used the ZM trailing arms/brakes and half shalfs/axles. It bolted up to the E30 subframe, prop shaft and rear diff mount no problem. the ratio is 3.2:1 I believe but to fit the m325 half shafts/axles you'll need different drive flanges as the ZM flanges are larger than the end of the E30 shaft. I dont know if the standard 325 flanges will fit into the ZM diff, anyone?

[jason90m]

. I dont know if the standard 325 flanges will fit into the ZM diff, anyone?
]

yep. the 325 diff output flanges will pop into the mz diff. im using the mz diff with the 325 output flanges and 325 half shafts. cheers, jason

[gazatron]

re opening an old thread, this is where im upto with the car at the moment. the car was on the road as an s50 see the first two pics. since then ive taken it off the road for a turbo conversion and had lots of the engine chromed and some coilovers , this is where im upto so far............. any idea where i can get some acl type bearings for the bottom end also some arp bolts??

[isTURBO]

[GraniteE30]

Hi mate,

That looking great so far, fair play to you! Thats gonna shift when its finished!

What sort of BHP you aiming for?

[curryp]

what sort of exhaust and fannymould are you using?

[orr]

can anyone tell me what that servo is off it looks nice and small

[ed325i]

[quote="old_skool_2002"]This may be of some help:

Golf MkII 1.3 servo (ATE item) moved over 57mm on my car


Did you put that bracket on ?
Mine hasnt got it.

[orr]

thanks i have a golf gti one fitted,it must just look smaller in that photo

[gazatron]

[mattm]

Christ on a bike!!! That looks crazy!!!

Top work mate. My hat goes off to you!

[bss325i]

Hats off to you sir!

[Jhonno]

Christ on a bike! Bet that will shift..

[bss325i]

Out of interest, do you get fuel stavtion problems when cornering with less than half a tank? Also what fuel pump and tank are you using?

I ask as i have this problem with my S50B30.

[gazatron]

dont really get starvation never run below 1/4 of a tank if it can be helped, got a walbro 255 as low in the tank as possible. When we go past the 550ish bhp with a bigger turbo going to get a swirl pot and a bigger pump maybe a inline one too.

edited with spec i have remembered!

yeh it will shift i hope! i was just curious if there was any other rhd ones as i havent seen one, only lhd`s?
