[e30_Turbo]

(ow but it pinks at 4k and above, so what )

I know what it is, I just need to get into the ecu again and change the settings a little, all's cool.

My car share buddy, whose just been on a multi car track session reckoned it was as fast as the impreza they had and he drives a daewoo. So it was certainly a fun run home, not high speeds as such but the acceleration was proper heart stopping momments not knowing exectley ho fast it's gonna go is quite a strange feeling. Everything is sooo much louder, the dump valve made us both jump and watching the boost gauge slam 1/4 round instead of just twitching was awesome.
Wastegates still my favourite noise so far, damn cool sound, I think every bmw should have a wastegate (e30's especially )

We must encourage all memebers to turbo there cars, especially toby and andy335, we can see you two are keeping a close eye on these threads.

When i accidentially turned my wastegate the wrong way i nearly sh!t my pants when i pressed the acelerator about a third of the way down round a corner, it literally jumped forward! god help anyone who dares press it all the way down round a corner. But that way it pinks above 3500k so i HAD to turn it back!

Sounds like you are having a wail of a time Mark, going for an MOT in 2 and a bit weeks, no washer bottle, very rich, and generally a bit of rust on the car. Lucky i used to work for the garage, hopefully call a few favours in.

So toby you looking out for a LHD e30

I am watching and i can't wait to see some Turbo action at the Donington show, are you comming to the show ?

I'm going to finish modding my engine in N/A form and see how it is, but those damn turbos are very tempting !

I think Toby has caught the Turbo bug too

No i don't think so, i'm far dowwwn south, plus i'm at uni so don't really have the time.

Yeah thats the best thing to get the engine sorted N/A first then when you feel the urge....boost it.

There was a LHD 325 in my local paper with a blown head gasket but no price, probably only wanted Ԛ£50 for it to get shut!

[jmc330i]

but those damn turbos are very tempting !

You can say that again. My M20 is sat in the garage with nothing to do and I keep reading these threads and getting ideas.

Although if I was going the turbo route, Id probably put the M20 back in the Sport and turbo the S50 because well, why not??


When we getting some vids of the turbo monsters then?

[Andy335Touring]

Just found some thing that might be of interest to you F/I chaps, i found a place that sells M20/M30 thermostats with differant opening temps so if your cooling is struggling a bit you could may be fit a 'stat that opens earlier ?

Opening temps are 71,75 and 80

I have just looked at an old M30 stat and it is marked up at 80 but this wasn't a genuine(sp?) BMW 'stat but it should be the same ?

The ETK says its the same 'stat in the M20 and M30, it also says 80CEL in the description so thats got to be refering to an 80 opening ?

Type in your car type ->Engine->cooling system

I was thinking i could use a 71 for summer and track days, and then use an 80 in the winter ?

no i don't think so

i was thinking about getting a LHD because it would mean using standard turbo manifold downpipe etc (lots of turbo m30s in the states and you can buy complete kits) but i think if i make my own manifold or start with a standard one upside down as has been suggested, a turbo will go in my RHD shell - at the front and high up.

going to look for turbos now

You are going to have to find a monster of a turbo for that 3.5, i think on e30tech one guy raves about holset hx40 turbo. I think its a very large diesel turbo, but apparently they are developed far superior to petrol ones. This spools at about 4000 rpm on and m20 so i would have thought on your 3.5 it might come in at about 2800-3000rpm and probably hold up to redline.

It would certainly be a torque monster with any sort of turbo, you'll be able to rival glenn then for torque! Incase you haven't already looked, look in the F/I links these provide good resources.

MAX boost so far

[320Touring]

MAX boost so far

vrooooooom PTSHHHHHHHH!

looking good, mate-just gotta get it up to the RHS of the gauge now

[Jon_Bmw]

Wicked thats about 7.7 psi is that spiking up there or continuous/held boost. If it is you must be wipping along! between randomly putting the clutch in to hear the whoooosh chirp.

Thats peak spike It hold's .3 and rises from 3k revs to .5, I have a record function on the gauge so I can watch it back after, it's rather cool.

The kick in the back is awesome, I FEEL the acceleration again, although we all know that wears off after a while

[Turbo-Brown]

Getting close!

Just gotta do a little bit of port matching with the Dremel tonight / tomoz then the pressure takeoffs for the various odds and sods need drilling.

Should have them done by next weekend which just leaves the various exhaust bits to sort out.

Will it all be done by the end of next week?!

Who knows

[Toby_Unna]

well as if you haven't already got enough on Alex...

i'm having problems (conflicting info!) about which turbo to buy.

a couple of people on the e30tech/turbocharged forum have told me garret GT40/Holset HX50 minimum, to make sure it will give good boost to the redline and to make sure the boost doesn't come in very hard and early leading to uncontrollable wheelspin. But these are very big and very expensive turbos, twice the price of the T04b and T3/T04e hybrid listed on turbocalculator.

However... i'm aiming no higher than 300bhp and i guess i want the turbo to make good boost from 3/3.5k to 6k. so with this relatively low boost in mind do you (/anybody) think i'll need such a big turbo, or will one of the T04s be sufficient?

If i NEED a big expensive unit i WILL shell out the cash for one, but if not, i don't want to unnecessarily build 450bhp capability into the setup when i'm not going to want that for a long time/ever! 230lbft still feels pretty nice at the moment!

UK shipping is reasonable from turbocalculator and the exchange rate is nice, and i have money burning a hole in my pocket!

[e30_Turbo]

Try http://www.essexturbochargers.co.uk, they know there stuff and have had me on the phone a few times. Should be able to help

[Toby_Unna]

brilliant cheers Mark will give them a call

are you going to Donnington then?

[e30_Turbo]

No worries

I'd love to come to Donnington, but I NEED to swap heads and get the tuning done before hand, Ant has my WB and I need another laptop, ow and some money too So not really sure if I can or not.

Pity it aint after payday

[Toby_Unna]

ah well.. would have loved to see your car though!

have been buying bits:







i'm HOPING this is the same volvo one as Ant has (because he squeezed his into the e30 front mask, and it looks a bit marginal!).

anyway it only cost a fiver (yes!) so it wouldn't be the end of the world if it's no good

no going back now, i have a full Ԛ£5 invested in turboing my car so i'd better do it!

[Jon_Bmw]

Haha One more to add to the list lads. That looks like the right intercooler Toby from memory, seem to remember seeing that one in another e30. Its nice and big, but quite a thin core so you should be able to sqeeze it in unless you had to remove the rad forwards for the 3.5??

I know what you mean about the americans suggesting huge huge turbos, they have a habit of that, I think that a holset HX50 to be honest is serious overkill, but then americans think big is best i suppose. They said my dinky turbo would never produce boost and but i can tell you otherwise!! The compressor maps are the best thing to look at, but its an art even to work out exactly what they mean.

Have you decided on FMU or megasquirt/other standalones yet?

Jon

[Toby_Unna]

that holset says it's suitable for a 15 litre truck

and while i know a 15 litre truck revs low and doesn't make all that much power, but that's still a very big turbo!

i may be wrong.

[Toby_Unna]

i think i'm going to try to do what you have to start with jon, if i understand right. motronic, afm and a rising rate fpr?

i just don't know yet if the ecu chip will need remaping as well?

megasquirt ultimately, no doubt. Andy335touring's NA car runs so nicely with emerald, as far as i'm concerned standalone is the best way to go.

if you have the cash

[Ant]

Nice lookin IC there Toby Its the same unit as mine so it will fit 100%

Be nice to get a spare intake modded to put the TB on the passengers side Toby, you are gonna have no room going in and out the same side unless you want to use a realy long charge pipe run, which is OK but will absorb a lot of heat after the IC has removed most of it, might be worth looking into that one M8??

As for the FMU vs ME/Standalone....... the costs are very close, a good RRFPR(new) is a good Ԛ£200 in the UK, MS is the same basic cost + approx another Ԛ£75 in sensors and TPS

[glenn]

toby
my opinion is the garrett T04 is plenty big enough.
it's what is fitted to the rs500.
the rs500 we had never ran out of boost, and was set at around 25psi to just under 30psi.
some t4 cossys are way over 500bhp.
i think it should perfect for you!

[e30_Turbo]

You could ask the guys at bavariacars in Oz, they have a m30 turbo.
erik@bavariacars.com.au

[Toby_Unna]

i can be pretty thick sometimes

I've just spent 3 weeks researching a PPC article on the cossie/rs500, i know the rs500 used a t04 turbo and that it can make a lot of power... but did i make the connection between that and my car? no i did not

thanks for the pointer Glenn

I tried emailing them about there manifold but i never got an answer

[Turbo-Brown]

Well, that was quite a satisfying day of machining

I wasn't too happy with the original oil takeoff I made (pictured left) so I redesigned it. The three holes are tapped to take M10x1 brake fittings and are to feed the two turbos and the oil pressure gauge. The threaded hole on it's own is for the oil pressure light switch.

The giant bolt is hollow and just needs a couple of cross drillings for it all to be done

[Andy335Touring]

That looks good stuff mate, i wish i could that type of work

[lentec]

Good work mate!

[Ant]

as fook Alex

[dlatch33]

Good work guys
been an interesting read. is there a book running on who's will go pop first?
my bet it fozzy he is boost happy

[Jon_Bmw]

Naa not fozzy's he's in control with megasquirt, my bet is well....my own.

I seem to keep missing this thread, loads of posts have been written since I last saw it. Alex I need your machining skill and machines.lol. As ant said cool as fudge.

Yeah Toby I've got larger injectors/tweeked AFM/FMU(different from rrfpr) and of course motronic.

Seen the other thread Ant, about standalone, you've got me thinking. My brother is doing a degree in electronic engineering so he would be able to put all the boards and do the nasty soldering and the alike. How much is megasquirt in kit form, just the basics and sensors. Damn you Ant for opening that other thread, you're just teasing a poor student!

[lentec]

Been doing a bit of turning myself!

8" new pulley!
cant physically fit anything bigger on my lathe!

[Turbo-Brown]

Buggering hell Len, that's a great big pulley!

I've been busy too getting the TBs ready. Little bit behind schedule, but I'm still quite chuffed. The links between the actuator bar and the throttle spindle links aren't in place yet:

[lentec]

Masterpice as ever
