There was a great article from Grassroots Motorsports awhile back. They did the install. I know the fuel rail is changed among other things.

Alex,

The biggest bang for the buck without doing a rebuild will be getting rid of the AFM and going MAP with Alpha N. Get your ITB's of choice. If you can do the cams now, then do them now and then get your tune with whichever standalone you choose. Talk to your local tuner and see what they like to use. The only other thing that will wake up the motor, but not add any HP but make it feel much better will be a lightened flywheel. Get one around 11-12lbs and made of steel if you can. You can take M20 FW's and swap the ring gear from your M42 or you can change the starter to an M20 with the M20 FW.

Those are my suggestions for you.

Good Luck!

Cheers,
~Ralph

Hey Alex,

This is a tough choice. It all depends on where you are going with the engine and it's development.

The dBilas unit is 45mm and they now have other options. The RHD drive option is 44mm.

I've had the dBilas and I would probably opt for the RHD if I were to do it again for the street.

For the track....I still have my slide throttle assembly sitting in a box. 

No matter what size you choose, you still need to have the engine tuned. My suggestion is to get rid of the AFM and go MAP with Alpha N.

Lots to think about my friend. I hope I didn't confuse you.

Cheers,
~Ralph

tomasb,

I'm going to guess that you had a complete head rebuild? valve guides and all?

I'm not sure how you can tell that your cams are in time with your crank from the oil cap but ok.

Have you done a compression test or leak down test? If not you can start there.

You can also check to make sure that your plug wires are in the correct cylinders.

It could also be that you're off by a tooth or more on your timing chain. It could have slipped during installation.

I would pull the spark plug in cylinder #1 and put a long screwdriver in there and bring it to top dead center. Then I would check the reference mark on the crank pulley. See if the marks line up on the pulley.

Cheers,
~Ralph

tomasb,

Did you by any chance tighten the lower ones first and then try to tighten the upper ones after? These need to be tightened by alternating cylinders and in a very slow fashion. It looks like you have too much torque and if you try to tighten the upper any more you may snap your cam.

My suggestion would be to loosen all of them and start over. Make sure They are A on the exhaust and in the correct order.

Now you're on the right track!!  You'll also need to add another keyway (woodruff key) since the one on the M47 crank is not in the proper position.

You need to "turn down" the nose on the crank until the gear fits back on.

I can tell you that you won't be using the standard M42 rods and pistons with a M47 crank.

You need to do the math to figure out how it will work.

« on: October 28, 2021, 06:41:11 AM »

JuliusE30,

Here is an example of the stock M42 set up.

Desired Compression Height = Block height - (Stroke/2) - rod length
Desired Compression Height =*   ** * * **212mm - (81mm/2) - ((140mm[Honda rod]-.15mm{protruding out of block}))

212-40.5-139.85= 31.65

31.65mm is your stock compression height.

For a turbo you will probably have the piston recessed into the block a bit. So what compression will you be running? Well that all depends on the pistons, rods, head gasket and the crank. Are you shaving the block?

There are a lot of calculations.

Cheers,
~Ralph

Hey JuliusE30,

This is a tough one.....as I've said over the years to many people, Do your math. Then do your math again.

It doesn't matter what looks "beefier", it's what will actually fit into your math equations to make it work.

You need to plan out the whole build before you get any more parts. Especially if you plan on doing a turbo.

Do some reading. There is lots of info on this forum and others. There is no "one magical solution" to your project. You can make lots of things work you just need to do the math to make sure they'll fit properly.

Maybe someone who did a turbo will chime in and give you a starting point for a good "recipe"

Good luck with your build. Keep us posted on your progress.

Cheers,
~Ralph

Did someone say stroker  ...... I went directly to my BMW dealer and ordered a crank for an E46 320d. Had my machine shop turn down the nose to fit the crank sprocket and add a keyway. I also figured while you're there to just lighten the crank a little bit. Not sure what the going price is these days but that's what needs to be done. You could go the M47N route but you'll need that adapter for the nose. I believe Metric Mechanic can make you one. Then you can weigh out your options as to which one fits your wallet better. Good Luck!! Plenty of info on strokers and I have one piece of advice for anyone doing it.......do your math and then do it again to be sure. And maybe a 2nd one too.... Go with at least 11:1 compression and get some good cams.

Cheers,

Suspension / Re: Restore 1991 318is to stock height - Much confusion, PLEASE ADVISE

« on: March 29, 2021, 11:45:04 AM »

Here is some info for the E30 that I researched and got directly from H&R about 8.5 years ago. HTH

I checked into it a little more and the 29664 would be the option to use if you wanted to be a little lower than the standard 50404 kit.
Rates between the two kits are comparable with the 29964 being just a little softer in the rear.
I hope that helps.
