Turbo Build

Discuss general and Technical 1991 - 1999 BMW e36 Turbocharging & Supercharging information & questions here. pppppssssssssssssstttttt! Whether its building up that nasty Euro S52 for mild boost or prepping that that non-vanos m50 for 30lbs of boost, share your experiences, tips, and build threads here.

Turbo Build

Postby JFM325is » Mon Jan 23, 2012 2:42 am

I saw a post on the tech about a turbo build where the OP put a volvo intercooler in and it looked very very stealthy clean. Now to my point, a friend of mine crashed their 740 turbo volvo and she is now going to junk it. Since it was a rear impact her intercooler is still intact and I am going to be taking it to start my turbo build. Looking for ideas for this build to take into concideration. This will be a long standing thread probably, since I dont have a lot of money and its going to take some time to get all the parts I want but let me know what you guys think I should do so I have some other things to consider. Also I have a vanos unit and heard that sucks for turbos. True? False? let me know!

Just to be clear I have spoken with Euro about this alot already and have kind of an idea on where I want to go with this but just looking for more input and to have my own thread about this.

As of now this is what Im looking at:

WAR Engine managment
WAR MAf
WAR 60lb injectors
SPA5000 turbo (not set on this what do you guys think?)
Headers (dont know what to get but I kinda want a top mount)
DP?
Oil lines?
Piping?

so yeah there ya go lol

if the volvo intercooler fits then go for it, if it requiers no cutting or modification then i would vote for it. WAR (you know how i feel about this already so if not search back on another turbo information thread). Its not called a hearder any more incase your having issues searching for turbo hearders. its a turbo manifold and good n tight makes some great parts and are tested but there pricy. I my self have been looking for a manifold but am unable to find one for the e36 for a resonable price.

dp you can build your self with a welder and a hack saw and about 1 u bend pipes from ebay (for the exhaust and dp your going to want all manderal bends as a 2.5 with a crush bender makes it into a 1.75" bend and greatly reduces flow.)

oil lines i went with ebay not my favorite choice but i think vac sells a supply kit that connects to the oil filter housing. the return line will need to be either tapped into the block or into the pan and must be above the oil level line.

piping im assuming you mean intercooler piping. ( i went with the manderal bent piping from e bay and looked great however when i cut the pip in half for a 90 degree bend there is a hump in the process of manderal bending the pipe. this cause a boost leak issue and alot of time to fix every pipe. ) i would plan out what bends you need and order from extremepsi since i think there parts are better and dont plan on cxutting the pipe to get your 90 degree bend. this will save you some time as well.

you forgot a few things i would get for sure would be a wide band so you can monitor if your running lean or rich.

oil pressure gauge oil temp gauge and boost gauge as these are sorta important to know but not a neccessatie.

afr gauge that i saw that was sweet was this one. (edit cant find it bc i think i saw it in a video) but it was just a gauge face that you would look through the vent and see the afr gauge. (i like the stealth look so all these things to me are important) if you dont care then do what ever and mount them where you want to just prefrence.



as for the turbo i need some more information i cant find any values for it to compare it or even match it to a compressor map to show you how well it will go with your build.

I figured as much but I really dont want to tap into my block.. Fack

Yeah I know its called a manifold, I just put down header...it was late lol I seem to find the best deals for mani's on bimmerforms so I will probably end up finding one on there.

Forgot to put down gauges. Sorry, yes these will all be added. I am going to have to figure out where to put them as I do like the stealthy look so yeah thanks euro for the info!

when i boost the e36 i plan on getting the center (sun glasses area) gauge set up with 3 gauges.

lol i suppose you got me there. I still dont like the way they look there though. I might make a PODI holder for my steering colmn but havent put to much thought on that yet. I will cross that bridge when I get there. For now gotta focus on the more improtant things.

Soooo ive been thinking.... hard... and this is very dangerous because I come up with unrealistic goals and then try to accomplish them and end up fucking everything up. Anyway I was thinking... because our cars (325) come with the dual exhaust out why not make a small twin turbo set up.... As in have 1 turbo per 3 exhaust ports... Small turbos that dont take alot to spool but then combining them at the intercooler. Is this resonable? is it even something that could add power? lol I have no idea I was just thinking of it.

May not add power but it would definitely reduce turbo lag.

Well I thought about it more but I dont know if this is logical. PSI is generated by how much pressue is in a certain space. The smaller the space the easier it is to obtain a certain PSI. So if I have 2 turbos running at 6 psi and the both interject into a pipe that is the same diamiter as the pipe there were previously in would that mean that both intejecting flows would increase PSI to say 10? I know it wont double it doesnt work exactly like that but you would figure it would increase pressure alittle bit causing more PSI. Or am I getting the whole concept wrong?

psi is just a restriction of air flow. what yo need to look at is mass flow rate for each turbo in lb/min of air.

this way you can match two turbos that will equal one larger one. you might loose the upper area power but its up to you. two times the work for the same power

its all still theoretical. I havent started building it out yet. Just thinking of ideas. But if everyone starts to agree that this MIGHT make more power and a stable system then I have no problem testing the waters to see if it can be done. Although it will take me awhile to get the money to get all the parts but still.

Google E36 Twin Turbo Hulk and youll find a build thread on it and a nice facebook page
