Title: My M42 turbo build
Post by: George77 on June 15, 2008, 06:19:45 PM
Hi guys,I started the project 2 month ago and it took me 4 Saturdays working from 8 to 14 ,after that I could take the car out for a little tour around the block.I used an exhaust manifold which was designed for a six cylinder engine (m50,m52....)and to be a bottom mount.I cut the last two cylinder and made an adapter between the manifold and the turbo.I'm using  310 cc injectors ,stock fuel pressure regulator and I managed to control the fuel and spark with emanage blue.I went with 3" downpipe and exhaust ,I'm using a 3" magnaflow muffler and it's not loud at all.I hope I can share some pictures,last time when I  have tried I couldn't.I just tried but I can't share  ,could someone help me with that.

what kind of numbers you think your getting out of the turbo?

The first two weeks I went with 5psi because I didn't have the emanage hooked up for spark control and then I raised up to 7psi so for the last week I'm going with 7psi.I'm looking forward to dynotest the car but I still have few things to do ,like adding a fuel pump  and to put a bracket  between the exhaust manifold and engine block.I can say that it's a big difference,the car pulls nicely.

I don't know if it's any. If you can't just try hosting them on Imageshack.us or something like that. If that doesn't work email me them (Just PM if you want my email) And I'll host them for you! -Preston

yeah, i would recomend hosting on imageshack or photobucket, and then hotlinking them to here.

Ok,these are the pictures,hope it's gonna work,  http://s284.photobucket.com/albums/ll4/george318/       The pictures are not in the proper order but I hope you'l figure it out.

So whats the info on your build here? Any engine work done? What size turbo are you running? Software? Questions questions answers answers lol:D

I don't have any work on the engine done yet,but I'll change my pistons and the head bolts ,I will go with a stock head gasket,I'll change the flywheel and the clutch .The setup is:
-Volvo v70 turbo (td04-14) I think,i'm not sure if it's14 or 15
-Ebay exhaust manifold for m50,m52......,which I cut the last two cylinder
-310cc injectors
-emanage blue for spark and fuel
-2.5 inch  IC piping
-volvo 740 turbo's intercooler
-custon 3 inch downpipe and exhaust
If anyone know about how much power a stock clutch can hold ???

Your best bet is to just do an M20 flywheel upgrade, since the clutch is physically larger and the OEM clutch has good torque capacity already.

I'm curious of how you are adapting emanage to suit your tuning needs. The idea of using another elbow added to the cut m50 manifold was something I thought may solve the issue of hitting the strut tower, glad to see it actually is something that works, haha. This is exactly the kind of build I like, low budget but very well thought out. Have any more details regarding the build, I have looked at all of your pictures but some more insight would be great!

More info on the emanage?

speaking of budget, what was the cost of it so far? If you got any wild deals then what would the cost be at average used prices?

I'm running 10psi with emanage controlling the fuel and spark,the hardest thing it's to make it suit to control the ignition timing,because this thing it's desingt
for japoneze cars witch has a 5V signal going out to coils.You have to interrupt the low signal before the amplifying transistors and go in the emanage and the out signal from the  emanage to go in the transistors. And there is another thing,you need some resistors for the injection wiring harness or you will get error codes.

the budget was quite low because I got the turbo,injectors and the intercooler for free,other wise I would go with a BIGGER turbo,with this one it's like a factory turbo car,but that's for the upgrade project.As for the price:
Exhaust manifold   150$
emanage the unit     200$
All harnes and pessure sensor for emanage     500$
metal plates, for flanges  30$
3" exhaust pipes with clamps 100$
muffler 120$  on sale
2.5" piping kit    150$
wide band kit LC-1  280$
   
About that free stuff ,I'm mechanic  at a garage specialized in Volvo, VW,it's just me and the oner,but I'm a 10000% bmw guy,I love bmw

If you ever wanna get another "kit" together and sell it I'd definitely be interested!

Nice job

If you could possibly post a wiring diagram of what you did that would be awesome and much appreciated. I have access to the units and have stuff for a turbo kit literally lying around, the management has been holding me back.

I'll try to post some diagram ,if you have some soldering and some electronic knowledge it won't be hard.

After 3 days of fights with the LC-1  I managed to make it work properly .This thing it;s so sensible to the power ,if the power  drops to much during the cranking goes in recalibration again and because the engine is running it doesn't recalibrate right ,the O2 sensor it's supposed to be in free air during the calibration.

I just drawn a sort of diagram. http://s284.photobucket.com/albums/ll4/george318/?action=view¤t=Untitled-1.jpg  Can someone tell me why I can't post pictures directly I need some help with that.Do I need 10 000 posts or something????????

and here a picture  http://s284.photobucket.com/albums/ll4/george318/?action=view¤t=IMG_1055.jpg where you can see how I cut the left transistor's leg and get the signal from circuits board ,go with the signal in the IN of the emanage and the out of the same channel go back in the transistor's leg.

Brilliant and simple I love it, a detailed how-to would be very popular!

Keep us posted on the progress!

To do what??The turbo thing or just the emanage adaptation??

This is the second time I have seen people using M/S50 ebay manifold with the extra 2 cylinders cut off.

Curious if you have any more thoughts on going that route vs. buying one specifically for the M42.  Obviously price is the biggest factor.  Power numbers could potentially be lowered or at least not optimal..... but if that were the case cost would outweigh the loss (which would be minimal I would guess).  Any fitment issues using that manifold trimmed down?

Thanks!
Title: My M42 turbo build
Post by: George77 on August 10, 2008, 12:08:12 AM
1st factor was the price,it's 8 or maybe 10 times cheaper then lets say 666 one and I'm pretty sure that can handle 300 hp with no problems.And for the fitment ,I used 2 sets of exhaust gaskets cos with just one the turbo flange it would be to close to the valve cover,mostly to the valve cover gasket which is from rubber so...As long as I'll use this engine I gonna keep the manifold.I'm thinking about a m50 turbo and 80% I might use the same model of manifold,I don't think that it's that bad.

love your step by step pics, brilliant workmanship.

Have you thought about putting some fins on your copper oil exit pipe coming from your turbo, to kind of compensate for the added oil heat? How does your car perform after the new install?

Post by: George77 on August 10, 2008, 11:46:02 AM
Thanks man.It crossed my mind but I was thinking more to use some how water ,cos it's easy to work with copper,it's easy to solder it ,but I don't think it's really necessary.My car runs very well at 10 psi,but I really need a bigger turbo ,this one it's to small,chocks my engine ,if with this one I can run 10psi ,I'm thinking that I'll be able to run maybe 1-2 more psi with a bigger one,the engine it's bone stock.

my engine is absolute stock m42 aswell, which makes this 11 to 12 boost REALLY interesting cause i haven't seen anyone do it yet. it's probably been done, but i don't know if it's been done on a stock motor. keep us updated

I have an emanage blue with the spark & injector harness and map options (Got tired of my crappy SAFC-II). Mind sharing a wiring write up with me. I think it would be highly beneficial for everyone.
