another budget turbo build...bottom mount

[tglaze]

so i had been wondering about what sort of power i could get out of a stock m42 if properly set-up and tuned and without modifying/deleting/re-routing/relocating any thing if at all possible.  this is my own personal car and started working on it little at a time as a had time in-between working on actual paying customer's cars.  I posted up arigionally over on e30 tech but realized it would be more usefull and appreciated over here probably.

In order to not have to move/delete/change origional components, i decided the only way to do that would be to try and make the setup bottom mount.  I havnt seen one done on an e30 so i was even more excited to take on the challenge. oh, and did i mention i plan on retaining the a/c as well??

motor was pullled, parts were cleaned as needed, all new bearing, seals, timing chain components.  new stock head gasket and bolts, and thats about it.

turrbo is a garrett gt2871r with origional 12psi internal setup.

the pics should explain the rest.



very inexpensive and efficient way to run vaccum lines, looks nice in the engine bay as well



might as well as some cooling capacity/efficiency



clean parts



strpped down



back together



FMIC had to remove aux/ a/c condenser fan    plan to add smaller one when it warms up



bottom mount log manifold





very tight in there....



managed to fit a 3" intake all the way to the turbo.  used DEI intake sleave to keep the intake at or near ambient temp and wrapped the manifold to help keep temps down



intake shoe-horned in there



origional coils and windshield washer resevior put back in factory locations un-modified



MS PnP for m42






update later when I get more done...

[tglaze]

turbo outlet barely sqeaks by a/c, motor mount, subframe and steering rack





even the belly pan still fits un-modified



intercooler ish all done






on tap....
swap diff
rebuild driveshaft
swap fuel pump
finish downpipe and exhaust
install guages and wideband

huge compliments!
all fit great there with that short manifold.
don't complain about space because in my e36 it's really a more tight fit than your, and I'm doing all possible to not remove A/C compressor or anything...
 
waiting for the MS installation details / maps
PS: great turbo

[tglaze]

thanks.  
on the e36 the subframe is further forward so there is a bit more room actually in the turbo area if you do a bottom mount.. it is a bit tighter on the fender side though.

 the obx manifold will work for you and you should be able to get around your a/c. witht he intake.  i actually have one and it is quite nice. they are made from what looks like schedule 10 stainless and it comes with a downpipe. i was hoping to be able to use it slightly modified or something on the e30 but that pesky subframe is right there in the way.  so, needless to say, its available.

I have already the manifold, a great bullet proof Neukin. Last week I fitted it in the car only to see how it would fit with my T3 60 trim turbo, and there is not so much room because of the engine mount, and A/C compressor is at 4-5 inches from the inlet of the turbo;) I'm fighting to have the charge pipe over the subframe so I need to do a lot of pipe work
The only fucking error I made was to choice the manifold for internal wastegate... I will need to do a custom actuator bracket, so some fab would be required.
 
I think that in the next 15days/1month I should have it running
 
- what injectors you'll use with the MS?
 
- what size is the elbow reducer on the Throttle body side? is a normal 3.5"?
 
 
you have a really clean engine bay now :cool:

[tglaze]

ya, 3.5" on the throttle body.

i'm running 72lb/hr injectors.  they are overkill, but i had them laying around and someday i will require that much from them.

just a thought from experiance on the location of your turbo oil return line that will not work you will blow your oil seals on the turbo. you have to return oil above your oil level you cant have any pressure on your turbo return. i have tried that same spot on the pan and things didnt work out to well.

Other then that looks nice great build.

i have definately had that in mind.  that entire side of the oil pan is filled with oil, did you wrap it around to the other side?  also, where was your turbo mounted?  i figure that the turbo is still higher than the oil level and it should still drain ok, simple siphon effect.

nece build

Where did you get that silicone intake boot?

I need one just like it.

[tglaze]

we sell them.  like $26 i think

[Danny707]

I need one thats exactly like the stock intake boot as far as angle goes and will match up to the afm.

[tglaze]

ok, i think i have an m42 car coming in tomorrow so i'll check it out and see what size will work best for you.  probably 3.5-3.0.  i think the afm is actually like 2.75 but that reducer doesnt exist so you have to most likely use 3.5-3.0. i'll test fit it tomorrow though

update:

got the diff swapped today and rebuilt the driveshaft.  
installed 88 and newer style m20 coolant expansion tank  to work with the 6 cyl. aluminum radiator i am using.
also found a hose at napa to work with that radiator to the m42 thermostat housing.  
made the downpipe as well
just a couple more days...

[nomad]

Is that log turbo mani custom made or did you buy it somewhere?
