General Topics / Sudden Drop in Fuel Economy?

« on: January 12, 2011, 10:54:10 AM »

My fuel economy is back to where it was, I changed from 91 octane to 87 octane and the car seems to be running much better. I am wondering if it had something to do with the Ethanol levels in the fuel in Colorado, the decrease in fuel economy started right when they changed to winter fuel with a much higher percentage ethanol level. I am still trying to figure out my idle issue though. I peaked under the intake and it looks like the hoses had been changed relatively recently, they looked like they were in good shape.

The car starts up fine even in the -2 weather we have been having, but it doesn't seem to want to warm up very fast. After I start it it idles at 700 rpm's, as soon as I put it in gear and move it jumps up to a 1200 rpm idle, and will climb to 1500 rpm every once in awhile. Seems like it should be the opposite, warm up at 1200, and then drop down to 700 when it warms up... Any ideas?

Well, I reset the ecu, swapped out the afm for the one that I replaced when I swapped over the airbox. Changed the oil, cleaned the airfilter. My mileage increased about 3 mpg but is still about 4 mpg different than what it was before taking of the "cold air intake". Now the thing is idling from 1200-1500rpm. This happened after reseting the ecu. Now I have 2 problems. Wish I would have left the thing alone haha.

I am thinking that the afm might have caused it, I am seeing more like a 15% decrease in mileage now, I am going to swap afm today and see if it helps. If that doesn't help I will order some new plugs. Frustrating to say the least. My hard starting has gone away though, so that helps.

I recently switched my stock plug wires to the 8mm performance wires suggested by the Grass Roots Motorsports article, at the same time I took the cheap "cold air intake" that was installed by the previous owner and swapped it over to my old stock air box that has a K/N filter installed. Nothing else has been done since then, and my fuel economy dropped from around 28-29 to 23-24. I have not been driving the car all that aggressively, so I am trying to figure this out. Is it the plug wires?

Engine + Driveline / M42 single mass VS M20 single mass conversion

I just bought the used single mass m42 flywheel off of the classifieds here and I was wondering if anyone knows the lowest weight I can have it machined down to. Going through this thread I saw 13 pounds, is that what I should do?

Swaps, Turbos, Buildups / Turbo M42 Race Car, Version 2.0

« on: November 20, 2009, 05:12:57 PM »

I remember when you guys were first building up this engine, what did you modify this engine with, stock rods, and lower comp pistons? I sold my car a few months ago and the guy who bought it cracked the oil pan blew the engine and left the car at my buddies shop who proceeded to get it back for me for free. I was thinking about rebuilding and turboing the engine and it seems like you guys are running the most reliable set up out there with very good results over many race weekends. Is there a link to the original build thread?

Thanks

how hard was the sound deadening to remove, looks like you did a good job

I have found that dry ice works the best for removing sound deadening, get a couple of big chunks place it on the deadening for a couple of minutes then hit with a hammer and it will chip up, then go back with a degreaser to remove the rest of the residue.

This project looks great sounds like a really fun car!

How-To's / DIY M20 flywheel conversion

« on: March 26, 2007, 09:05:23 AM »

I need a new clutch and thought that this would probably would be a worthwhile upgrade, what clutch kit do you use, a m20 or can you use a m42 clutch? This uses the m20 flywheel, the starter pinion from and m20 and the tob from a 323 is there anything else that needs to be changed? What weight can the m20 flywheel be machined down to?

I found mine on bimmerforums.com, and also saw it listed for a lower price in the local newspaper. I had a 2002 that I was trying to get running for the winter so I could drive to work but found out that a new windshield would cost 350 bucks installed, and the car needed a wiring harness rebuilt and new brakes etc..

            So I went and checked out my car, even though its paint isnt in the best condition and the bumpers seem like they were put back on wrong after the partial repaint, I fell in love with the car as soon as I found it.  


            I talked him down from 4000 to 3500, probably to much but it was one of the first 318is I had found with a 150 miles it had all of its maitence records, and has been lowered with bilstien sports, has recaros out of a VW i think and it checked out great at the local mechanic.

I love it, in the first month or so I drove a canyon a night and put like 2500 miles on it. I have had no problems with it so far and am just now starting to think about what I would like to do to it...
