Throwing in the towel and going the LS1 route has been done before and cracking the 11's with a domestic V8 in an E28 would be cool but IMO not as cool as doing it with an M30. Is the justification monetary, mechanical or both? I am disappointed with the move from the M30 and still feel the goal could be realized with the M30 given a well thought out build and tune. Perhaps a better test of the E28/M30 as a whole would be timed laps on a road course, not autocross or drag strip. We know these cars were designed for high-speed maneuvering. Because of this, forcing an E28 to perform at the dragstrip is analogous to bolting up a 4x4 suspension and rock crawling. An interesting pursuit regardless.

It's really just about Hot Rodding and continuing to have fun with car. Ultimately, hanging with friends and building stuff is the real fun.

That's it hey Todd, nothing like having a drink talking crap and modifying cars/bikes. Wish I had a sweeny just down the road. So when's the four link rear end going in? [/quote]

Purchase an engine today. SPECs for LSX geeks:

2007 L33
all aluminum 5.3L with 243 heads (same as LS6)
310hp/335tq in stock truck trim

Removed from 2007 GMC 1500 truck with 80k miles. The L33 in 2007 was called the Vortec HO.

9.9CR should be perfect for low boost madness!

I'll start a build once I tow the car up to Sweeney's in 3 or 4 weeks.

Time to start - OPERATION BOWTIE E28

Got the LS-1 motor weighed today with all the accesories attached (A/C, P/S, Alt, wiring harness, ECM; etc). Believe it or not it weighed in at 481-LBS !!!

Don't spin it over 6K

I'll have complete control over the factory ecu with HPTuners. Safe rpm is 6500. I'll probably install ARP rod bolts when I change the oil pan to be safe.

My research shows 315lbs vs 390lbs in long block with no accessories. So will gain a little weight.

I think the t56 is 50lbs heavier than the G260. At least all the weight will be better balance and with a lower center of gravity.

That's the motor I eyed for the Bav... Looking forward to this.

I would do crank studs too while you are there.

No issues with the crank. This motor will take 75rwhp per hole stock with better fasteners.

I'm surprised that an all aluminum motor weighs that much.

Should be mighty fast, though.

mooseheadm5 wrote:I'm surprised that an all aluminum motor weighs that much.

That, plus the fact that it came in a truck. I thought all the truck motors were iron blocks.

LM7 (in everything else) is an iron block.
L33 (2005-07 Silverado SS) and LM4 (2003-04 Trailblazers and others) are aluminum block.

Are you going to stick with DBW or going manual? Have you decided on your intake and therefore your accessory drive(s) yet? I've thought that it would be nice to get a decent cam to move the powerband up a bit to emulate more of a higher-revving Euro-style V8. You won't even need to change the heads.

I've also thought the weight of an M30 at 315lb. seems suspect, as I've always thought that it seemed heavier. I've got a 3-liter block sitting on the side of the house and it is one heavy mofo. Maybe Todd can be the final arbiter and weigh this mess?

Look up Vorshlag's E30 swap with a 5.3 iron block. They have pics of them weighing the motors and trannies somewhere, although they were comparing it to an M20. For what you are getting with the swap, the weights, IMHO, aren't that big of a deal. Plus the distribution is set quite a bit closer to the center of the car.

LS1Tech.com has more info on this stuff than is possible to read in a lifetime.

Good luck, Todd, this will undoubtedly be awesome.

I am feeling greedy so this is my current plan.

LS6 cam
LS6 valve springs
BBK or LS6 intake
Conventional Throttle body
2000 F Body wiring harness, ecu and accessory package
GM MLS HGs
ARP Head Studs and rod bolts

and boost.

Thanks for the well wishes. It looks to be a lot of fun.

Todd, if you plan to do track events (the non straightline kind) I would suggest a baffled oil pan. The ls motors I have seen will run dry on track events doing high bank left turns. Especially oval racing, even though I doubt you plan to do that, it's something to keep in mind. I don't think their oil pans are baffled at all. My friend lost a healthy ls1 because of this.

Damn... V8 TT

I can't wait to see what she runs in the 1/4...

<12 4 sure!

Sorry I missed this one.

I've been dreaming of this one for a while. And we have that Z28 collecting dust. Shoulda seen the wife's face when I asked how long it was going to just sit in the garage. (She won't admit it, but seeing as that car is the most uncomfortable vehicle ever built, I suspect it will not be going anywhere.) It might have been the gleam in my eye that gave away my thoughts. All she said was, "No."



Looking forward to the details,

This is great news. LS based motors can get sh!tloads of power with minor add-ons. I have come from the e28 533 to a LS2 based platform. So much cheaper to work on and get power out of.

For those that are looking for a turbo conversion in addition to ls1 swap. You better get some $$$ thrown at your drivetrain. That amount of torque on these older parts is going to lead to a ton of blow ups. Invest that money into the drivetrain components to handle stock ls1 power consistently then add power.

A blown ls1/2/3 can easily make 500rwhp 500 torque. Have to get the car in a state that can handle that...because that is the min in regards to FI for this motor.

Todd

Are you looking to do a Daily Driver version of a swap? Something that someone can have 5-6 speed and AC..


This is a great project btw. Best of luck.

If you make an affordable LS V8 swap kit for E28s, I WILL come back to the BMW world. Well, kinda.

Don't wanna miss this.
Hopefully see it in the flesh if TedFest works out for 2012.

nice!nothing like pure american muscle!

Won't be delivering the car to Sweeney's for another week. Some eye candy in the meanwhile.







And check out this clutch. m30 stock clutch pictured for scale.

Holy crap! That is a large clutch.

Hurry up and get this done. Forget working on the house. You have a roof over your head that doesnt leak. So the car needs to come first.

Towing it to Sweeney's on Sunday! Let the fun begin!

I can't help but note that the clutch appears to be larger than the normal available space in an e28 transmission tunnel.

Will the car be getting modified to make space?

I think the tranny fits without mods.

Day 1

Travel 140 miles to Sweeney's.



Test fitting with foam block.





Stripped all the truck parts off the L33.



Ugly on the outside but like new where it counts!



So great to be back at the lair building an e28! Even better this time with Harper old enough to help out!

Did you have to fabricate the foam block? Pretty cool.

turbodan wrote:Did you have to fabricate the foam block? Pretty cool.

It's available from Summit, Jegs etc. It has removable heads. You can bolt everything to the block like a real block. It's very useful.
