745i manifold upside down?

[rod2190]

hello i was wondering if anyone has ran the 745i manifold upside down to make it a top mount setup, what problems i might run into trying to do this aside form the wastegate any info would be greatly appreciated

[johnnye23]

Shutting the hood.

[rod2190]

even if i'm using a k27?

[T_C_D]

I think the turbo interferes with the valve cover/cyl head.

[rod2190]

another quick question is an o2 signal clamp required to prevent lean tip in? if so where can i buy one or if anyone has an alternate solution suggestion i'm all ears i'm going with chip and fmu setup for now until my knowledge on tuning increases.

[T_C_D]

Which ecu?

[rod2190]

059

[rod2190]

1986 u.s. spec

[T_C_D]

No o2 clamp required.

[rod2190]

if i was to purchase a chip from u would the chip have to be mapped different if i was using a b35 head on b34 block or would your standard 059 chip work? sorry for back to back questions but i'm almost done putting my engine back together and have alot of little details i keep running into and need advice with i appreciate your time.

What boost level?

[rod2190]

well i'd like to go back and fourth between 12 and 18 if possible but if its better to stick with one boost level i'll just do that i'm gonna use a digital boost controller, and i will be using the bosch red 30lbs injectors

You will be limited to about 15psi with 30lb injectors depending on your location. The chip would be suitable for that boost level.

The coolness factor of a top mount is not worth the added complications.

i'm located in texas, so would the map be different for the b35 head or do i just order the one off your website

Send me an email when you are ready to order.

The TCD chip will be fine for you even with the b35 head. All you have done is lower compression even further than a stock B34. Not sure why you went that route since you have a laggy turbo and its going to be slower out of boost than a stock B34, but it will work.

[rod2190]

well i plan on going with a more aggressive setup as soon as i can supply the fuel and i get a feel for the current setup the k27 i have is a modded one with 60mm blade i didnt know the k27 was laggy i figured the lower compression would make it more reliable, i'm 22 i'm a collge student and this is my first turbo build so i might be miss informed so any info given to me to better my build is much appreciated i just finished mock up with the engine on the stand yesterday

[cvillebimmer]

And for the record, not the best idea to top mount a TCD manifold either.

Well, it looks like you will be getting rid of the MSD and the stock single coil parts so it'll clean up a bit.

This is a cleaner install.

[rod2190]

thats sick i hope to have my car at that status soon enough i want to learn as much as i can before i go with a crazy setup it be nice to be at 500rwhp within the next three or four years but i know nothing about standalones and tuning.... YET

[cvillebimmer]

Todd, yes! Much cleaner. Where are the coil packs on that car?

Can you recommend a brand/source for custom wires? I was also going to throw a turbo blanket on the turbine for good measure.

Single coil, MSD on my cars (always),

I can order you wires. Just need lengths, and the year of the coils.

To me it looks like we have a lot of work ahead of us.

[Bill in MN]

This is even more cleanerer

[cvillebimmer]

Bill, are you recirculating the CCV? Or using a catch can?

[Bill in MN]

Bill, are you recirculating the CCV? Or using a catch can?

It's going to a catch can mounted to the drivers side frame rail, then to the exhaust. It works quite well but I don't think it's exactly smog legal

Are you running a 1-way valve so the vacuum created by the exhaust can assist the evacuation process? If so, what valve did you incorporate?

[Bill in MN]

There's no valve. The line from the separator goes directly to a 45 deg. inlet welded into the pipe.

Understood. Exhaust passing this 45 inlet creates a vacuum yes?

OP, sorry for the hijack. Something to be learned here.
