My e39 LSx swap

Indeed. Bigger is not always better. Clay will have quicker spooling and usable power

Reasonably..

NICE! Your creativity continually amazes me. That is a trick setup.

Great build! Would love to see it sometime! I garage my car in Richmond.

Neat mount idea.

**RVAE34** · 12-29-2012, 04:59 PM

Peter, nice to see you in here. I sold the E34 to build an LS E39 as well.
Hope your project is coming along. Also hope to see you at cars and coffee soon.

3" downpipe.

Dear Jesus, can someone explain how a V8 copes with FI on only 1 bank of cylinders?

Very nice job!

He's not. There will be a crossover pipe from the other bank. See post 126.

Very cool, though I loved your E34!

LS power in an E39 is a very attractive option. My Beast is getting a new rear drivetrain, including a new diff, and a dry sump system, but should be ready when the weather warms up a bit!

That is all coming together beautifully! I take it that a 3.5" DP would have been very difficult to fit? 3" seems a little tight for the power you will easily be making.

looking great, FYI, many of the foxbody mustang kits do not use a flex piece on the crossover pipe. My old turbomustang never had one and it worked great for the 3+ years I had it. Adding one wont hurt but its not a requirement.

**M5Hunter** · 12-31-2012, 12:16 PM

Exhaust size has been a very difficult decision. I could have squeezed a 3.5" downpipe in, but after a pile of research I have found that many people with a similar setup are able to make 600+ at the tire through a 3" pipe. I think I am going to split it to two 2.5" pipes shortly after the downpipe. Also, the wastegate will not dump into the downpipe, so that will allow more flow once the gate opens. I plan to bring the wastegate pipe in where the exhaust splits to two pipes.

**M5Hunter** · 01-20-2013, 05:51 PM

Finally messed around with the car this weekend. My main objective was to figure out my wastegate and I feel like I have a decent design. On to the pics.

Also messed around with turbo drain ideas. The turbo being mounted so low has become a bit of an issue, but with some professional advice from Mr. 5nail5 I will come at it from another angle. I have decided to run an oil cooler, not only for cooling but to allow for a lower oil level in the pan while keeping the same capacity. I may also go with a 5.3 truck oil filter as its a bit longer. Other than that, I have just been gathering parts. I hope to start the engine in a few weeks.

**wheels4265** · 01-26-2013, 12:13 PM

Looks nice, wish I had your welding skills. Now you need to duplicate that design for the other side for the TT. C'mon, a TT will be "easy", lol. You can put the TT set up under the "one of those things I need to do while Im here" tasks. Dont you love us mond morn quarterbacks giving advice?

**M5Hunter** · 02-02-2013, 07:13 PM

I would love to run twins, but A/C is just too important to me.

Welded the wastegate port onto the manifold. Looks good, hope it works! After that I finished up the revised crossover pipe which is a little bit more aesthetically pleasing and wrapped it.

Also picked up a Suburban oil cooler adapter with thermostat. I was concerned it may not clear the turbo or downpipe, but with some creative bending it clears everything fine.

Hope to work on it more tomorrow.

mmm pretty manifold

sexual bumper

did you just heat the cooler lines with a torch and gently bend them? i'm sure the aluminum gets soft super quickly compared to steel

**M5Hunter** · 02-08-2013, 09:58 AM

no need for heat, aluminum tube is very flexible.

**M5Hunter** · 02-09-2013, 06:04 PM

Hopefully the motor is in for the last time!
I've gotten to a point where I have to spend a little less, so the Tial BOV I had chosen didn't make the cut. Went with a Godspeed Project 50mm, there are some f body guys that swear by it.

Looks like I won't be using foglights!
