m52 Turbo Build

[328iFun]

Thanks P.

This whole experience (coming from someone who doesn't or didn't a turn a wrench or paint very often) has been interesting:

1. It's amazing what these cars/engines are capable of in stock form with the right compression and tuning.
2. How enthusiast are willing to help one another. I don't think you would find this kind of support lingering around on other forums for other automotive manufactures or models.
3. Plain and simple, the best part of all is I can say "I did it" and that the car is absolutely addicting. Everyone who rides with or hears it, loves it. After taken my ole' lady for ride (and she hates speed/torque) she was even interested in what was happening and how it was working and driving the car.

I think at 7-12 psi, if you can drive the car correctly you may be able to make as much power as the average Joe pushing 18 and not knowing how to drive. And I say 12 because I've seen it creeps to 12 in 4/5th from time to time.

But it's not over yet, I have a spare motor in my garage that needs built

As for the spare motor, clean it all up, spend $500 on rods (or those nv m50 rods), cut bew stock rings (ill send you the tools to do it) have a proper oil drain welded on the pan and have it ready to go for the lower end. I don't think bothering with pistons and punching it out is worth it. You already have a copper spacer. Then prepare the head. Maybe buy valves, and springs. Have the head cut and install them your self. Then you will have a bullet proof setup.

Chances are, your m52 will live a long life. I pulled mine at 300k cause Pbonsalb set me up nicely with a s52 and forged pistons. But that 300k m52 is still sitting here in case.

Why ATF?

It flushes out debris better than engine oil since it is thin.

Lol.

Yes, you are correct. atf is thinner than oil. Thinner and cheaper = mineral spirits or reducer if you dump right into pan via dip stick hole

This sounds spot on.

I don't plan on pushing the M52 too much unless I need too. I've got a couple drag races planned where raising boost may seem fit.

But as far as my back-road driving 7-10 feels great. I don't like pushing it too much on public roads the car wants to run at 80 cruise and will hit 100 in no time - if I let it. But I really enjoy low speed, fast acceleration, and the torque. Ill often stay in boost till like 60-65 and left off, I just like how fast it gets there and the sounds.

By all means, walk me through the engine build, ill listen and turn the wrench! Would love a solid setup.

I like the idea of the 92 NV rods and stock M52 pistons with looser rings for a durable budget build. Refresh the head and use the ces spacer and cutring.

Non vanos rods and head + M52 pistons and crank + S52 cams =

Has anyone tried a set of eBay $279 rods ?

Look at this on eBay http://www.ebay.com/itm/161145203741

Is absolutely necessary to retighten head bolts at this point? Even at 7 psi?

Best way to do Without removing cams?

No rod bolts with those. The 279 option has bolts I believe.

you can fit a socket without removing cams.

Your saying he should take out his head studs and put stock bolts back in?

[328iFun]

Doesn't seem like a good idea...

I don't think I have a socket that fits with the cams on

[someguy2800]

craftsman and others sell small diameter sockets

[328iFun]

I could open a small shop after equipment I've acquired

The northern tool socket works. So does the craftsman.

I have used both

I have been spoiled with 3-4 boxes filled with Snap-on and Cornwell. But, have been paying them bastards $25/week for 20 years so, I guess joke is on me.

At least you have what you need when you need it.

Nothing is more aggravating than being in the middle of working on something and not having what you need. Even worse, knowing you have what you need but can't find it or don't have a back up. My shop gets so disorganized when I'm in the middle of something takes me a good day to get everything back in order

Opps, forgot he has studs.

[328iFun]

Now that everything else seems to working properly I think it may be time to get this $500 meth kit hooked up

I have a single nozzle, where do you guys think the best place on the manifold would be to tap for even distribution?

Put it pre throttle body.

I had it in the Intake Boot initially but boost blew it out
