Another M54B30 N/A Engine Build

Hi all,

Just as the title says, This will be a thread about my M54B30 N/A engine build.

I got inspired by Adam's (PEI330CI) threads here at E46fanatics, And decided to start this project about ~6 months ago.

My goal for summer 2010 is to have the new engine mounted and running in my 330ci '01 with about 340-350hp @ crank, later when I'm satisfied with the engine I will start working on the chassie. My plan is to use the car on both the street and on the race track. But I've noticed that my plans gets more and more racecar inspired, So we just have to wait and see what happens.

Adam Hale and Erland Cox has been a great help, Thanks!

I had Erland to do a cylinder head for me and the pictures below shows you the great work he have done to it.





Look at these intake ports, they are BIG. 50x27mm, same as Euro S50B32.







And exhaust ports:





The valves I'm going to use is Supertech nitrated steel 34mm intake valves, wich is +1mm from stock. And Supertech inconel exhaust valves, but they stay at 30.5mm as stock. I only got bad pictures of these, So I put up pictures later. The valvesprings will be uppgraded to Supertech together
with their titanium retainers. All this will be sitting under Shricks 272/256 camshafts.

I've decided to use CP pistons, 12,0:1. These will be mounted together with Eagle rods.











Compared to stock:









Many of you have already seen Pei330ci's thread "M54B30 oilsquirters (Version 2). I started working on the oilsquirter "project" about 2-3 months ago together with a friend that got access to CNC machines. If you want more information about the M54B30 squirters, I recommend you to read the great thread mentioned above, written by Pei330ci. But I'll show you a couple of pictures of this new version:











Test mounted:






The next step is to have the block machined for a 84.5mm bore, and then have all the rotating parts balanced and weight adjusted.

So at the moment I'm looking for a serious company that are doing all this and has a good reputation and are easy to work with.

I rather stick with one company instead of having 2-3 companys involved in this.

The crank will be balanced together with a clutch and flywheel that most of you will recognize.









Yes, that is Pei330ci's old clutch and flywheel. It has been torn down and cleaned, and putted together again with new bolts.
I'm sure it's good as new.

That's all for the moment, I will put up more engine realated pictures next weekend.

Regards

This thread should be dedicated to all the people who want to run 110 octane in there stock internals engines so it will make more power!

If I could re-consider my choice of compression ratio of the pistons today, I would choose a higher CR, Like 13.0:1 and have the engine run on E85... But thats to late now.

But at least we got 99 Octane pump gas in Sweden.

Damn you, I was wondering how you were going to deal with running 12:1 CR. I'm stuck with the 11:1 CPs...but seeing CPs in person gives you a better perspective on their quality. Plus, I called them up to inquire why my pistons (which are presumably the same as Adam's) looked different. They pulled up the CADs of my specific pistons and came up with an answer pretty quickly: great company.

For those who are wondering how extreme those 12:1s look compared to a (more) normal 11:1 CP piston, here is a picture of one of mine:

You should measure your pistons and calculate the CR just to make sure those really are 11:1.

I never heard of anyone who got the wrong CR out of CP, But I've heard alot of people that are using Wiseco and JE pistons that have had problems getting the CR that they ordered.

One tip is to always check aftermarket pieces measurements ect...

I will definitely be checking final compression ratio when I pull the engine and get it to the machinist. I ordered from VAC and checked directly with CP. After they looked at my job number and the preceding jobs I was told that they were originally a flat top design (Adams). Later on, they deepened the valve reliefs and added the dome to make up for the loss of compression (Mine). They will be checked to verify again, though.

Pictured below is my Supertech intake and exhaust valves.

The black one is the nitrated steel intake valve, And the shiny one is inconel valve.

I got home from work yesterday and found a set of S50B32 ITB's for sale.

I've been looking for these for a couple of weeks now. And I got them today.
And YES, I will use the ITB's.





1st and 2nd



3rd and 4th



5th and 6th



And test mounted to the head







And the clearence issues:







Also the bolt pattern is different. But the size and shape of the ports are almost a perfect math to my head.

I've already started the work on this... This drawing is of the flanges that will meet up to the ITB pieces,



I'll have it CNC'd in a week or two.

That's all of now, Mary Christmas!

Nice! What do you think the peak horsepower RPM will be?

I would guess around 8k rpm... Rev limit will be set at 8500rpm.
