Author Topic: Another budget turbo build. (Read 67353 times)

Awgy · « **on:** March 25, 2009, 02:04:42 PM »

I must say after reading Danny707, Bearsbmw and tglaze's builds, I am just itching to start one myself.

thanks for the motivation.

Goals are the same as Danny707 stated in his thread.

Parts that I do have:
Small turbo from a 91 Saab 900. (TE05 12B) I know... small.
22lb injectors from the same car.
Intercooler from the same car.

I traded a car that I had sitting around straight across for these parts at the local junk yard. I also got cloth seats from an e30.

As for the parts I dont have:
Turbo Header.
Fuel Pump.
Intercooler Pipping.
RRFPR.
Lines and Fittings.
PLX Wideband and Guages.
BOV (undecided) what even what to do about this.
and what ever else I cant think of.:rolleyes:

I have been doing some research for the parts that I dont have. Such as the RRFPR, I was thinking cartech but there has to be a cheaper solution for the same quality. Do you have any input on this guys?

OH... I have given myself a deadline. JUNE 1st 09

Ebay BOV.

And any adjustable rrfpr will work.

Nice, I'm hoping to finish my build early this summer too! all these builds are great

Also, prepare for some headaches.

Its fun, but alot of work.

Oh.. trust me, I am expecting some headaches. Do you have any pain relievers to help? I really dont want to start taking steps backwards once I go forward. And if (when) I do, I would like them to be small.

Test fit everything before you bolt it up and get it going.

The m50 manifold's up-pipe is interesting to fabricate.

Just set aside a week and you'll have it done.

As far as the BOV, I would look into a 1G DSM BOV, they are cheap on ebay (you could even get one for $20 locally) and they are a popular item for all makes of cars. They hold around 20psi in stock form and there is a mod you can do here http://www.thedodgegarage.com/turbo_bov_mod.html to make it hold over 30psi.

ibe been considering a turbo build but when it comes to a gas turbo motor im in the dark. i come from the turbo diesel world. we push 60+ pounds of boost without a wastegate,blow off valve. my 96 cummins 12v is pushing 980hp on fuel alone.

is the wastegate or BOV really necesairy?

You got it easy with diesel's, they pratically run on detonation. BOV has to get rid of the build up pressure in intake pipes when the throttle body closes or it can damage the compressor in the turbo causing it to come to a complete stop between shifts. With it open when you shift the turbine keeps spinning. Wastegate helps turbo spool up and build boost quicker, then at a set psi they open up, either to the atmosphere or rerouted back into the exhaust, so boost doesnt build sky high and destroy your engine. Your boost is dependent on the RPM's of the engine, the wastegate just controls how much of that exhaust the exhaust turbine really sees.

stock diesels are wastegated. i understand the part about boost being dependant on r's. im making zero boost under 3500 rpms but it makes upwards of 60lbs clear to the 7100 rpm redline. im gonna do some more research before i build my manifold and get started.

I have a little update.

PLX wideband is installed and works great!:D
I found a Mitsubishi BOV from an old SR20DET project that I had and forgot about. Part# K5T09
Ebay manifold is being shipped.
2.5" 2mm wall thickness intercooler piping is being shipped.

Just a few things left.

I found a oil filter cap from UUC Motorwerks that fits the E36 323, 325, M.
Does this fit are M42?
It comes with 2 1/8 holes for sensors. I was thinking of making one of the holes to a larger 3/8 for oil feed for the turbo. That is if it fits.
Here's a pic

I just got a ref ticket, I'll be selling my whole turbo setup as a kit if you're interested.

Awgy · « **Reply #12 on:** April 26, 2009, 05:44:37 PM »

I already most of the parts to be buying a kit.

Just need a RRFPR and the cooland/oil lines.

Any chance of parting away with just the RRFPR?

Danny707 · « **Reply #13 on:** April 26, 2009, 06:16:26 PM »

I don't use one anymore.
