how about a chip, k&n cone filter and exhaust for starters*th-up*

or just get nitrous:eek:

Nos and chip are to costly chip is something around $650*thmbsdwn* so maybe cone filter i have a 2 inch exhaust and a sports muffler :) but thats it, any other suggestions ?

i was gonna say shorten your gearing up a little more, but after looking it up you've got 4.10 already... idunno about anything past that for the street, i chickened out and went with 3.91 myself :)

if you've got a good exhaust on, then i'd agree w/ the previous poster- intake, chip, and then headers w/ a good aftermarket cat would be my route... if you don't want trouble from the cops around where i live that's about what you're restricted to, and only then when they have the proper paperwork...

which is why on my last VW i went on a huge weight-reduction binge- removed PS, the entire AC system, and a good chunk of the interior all at once- made quite a difference once i'd gotten a 16v engine in. whether or not you're willing to live w/o these amenities on a daily basis is your call... but if you don't have a lot of money to throw at the car right now, the colin chapman approach always helps :)

Get the chip, it makes a huge difference. I can already smoke stock 318's silly with my current setup.

like _dk_ said, the best HP gain for $$$ value is serious weight reduction. Don't know how serious you are about spicing up your ride but those stock seats weigh a ton, so does the factory carpet and A/C system (if you have it).

Whatever you do, DO NOT get a K&N cone filter. It's been proven many, many times that the cone filter only sucks hot air in from the engine bay. Dyno results have proven time&time again that the best filter is a K&N drop-in type with the stock airbox.

Randy thats exactly what i needed to hear! I have the K/N drop in in my stock airbox and people are constantly telling me to go cone, but now i see they were wrong!!!

Hey Randy,

I'm not saying your wrong, but when you dyno your car the car isn't moving, therefore the cone intake would suck in more hot air. While the airbox doesn't have a fresh source of air either, it is well protected from the rest of the engine bay's heat. However, when the car is moving, there is a fresh source of air and therefore would be difficult to tell which intake setup works better. The point of a cone intake is to be more free flowing and less restrictive while the car is moving. There is no doubt that the stock air box works better in heavy traffic conditions and basically any non highway driving. But on a race track, wouldn't the cone filter work better?

I've tried both setups. Infact I sold my drop-in filter to Terry. The cone filter felt slightly better, yet I could have just been distracted by the sound it made and thought my car was pulling harder when in fact it wasn't. When I tested them both in 30 degree celcius weather, no doubt the airbox w/ the drop-in filter worked much better. With the cone filter the car was torquless and bogged when trying to go from stop. However, if the temperature outside is just perfect, cool and low humidity, you really "feel" the car pull harder on those cool nights with the cone filter.

I'm not disagreeing with you. This is just a great topic to discuss for anyone who wishes to mod their cars for street or track.

Good point Bryan. The dyno tests that I mentioned where performed by my friend Sean with a '96 318ti on a dyno with a massive fan infront of the engine (if that matters). An E36 chassis has the option of using a heat sheild around the cone filter sealing up to the hood isolating it from the rest of the compartment. I think the best setup would be a true cold air system like Carbonio, but E30's don''t really have that option unless you go crazy with a sawzall and reloate the ABS system too. I custom made a heat sheild and had a ram-air snorkel right to the high-beam location which helped a bit, but I was weary about driving in the rain.

Weight reduction is definitely the way to go for the M42. I just pulled out the stock seats today and they weigh a tonne, it felt like at least 50-60lbs each!! I replaced them with Corbeau Forza seats which weigh significantly less, only 10-15lbs each max. The car pulls so much harder and the suspension felt much stiffer giving the car overall better handling. I lightened the car at least by 80lbs today which immediately could be noticed.

Put it this way. The 318 motor isn't such a bad motor; it's just underpowered for such a heavy car. Once you start to get the weight down, it really is a fantastic car to drive.

Weight reduction all the way!

Here's something that hasn't been posted yet. Switch out the (15 amp brown) fuel delivery fuse (9) in your fuse box for a higher rated one.

NOTE: This is a little dangerous. Bentley Service Manual for the E30 BMWs reports that swapping a smaller fuse for a larger one could result in fire.

But, when I bought my car it had the yellow 25 amp fuse already in it, which I later swapped out for the 15 blue because that's what the Bentley manual states it is suppose to be. After feeling a lack of power and acceleration I swapped the 15 for 25 on Sunday and the throttle feels more responsesive.

I'm not sure if this does anything bad to the electrical sys., but I have noticed a slight change in fule economy. My car is an '84 and yours is a '90 so the fuses may differ.

From a standstill he should be kicking your ass stock for stock anyways. He has literally hundreds of pounds on you. If you pull on him at all it's a sign of solid power gains.

anyone can confirm this?

I might do it if it gives more power*uzi*

hmmm I got heat shield, and it works.
we compared temperature (by touching :) ) on my car vs openwheels car (no heat shield) and what a difference.
and c'mon the sound of the intake is just amazing

I shall fill her up today and see if there is any change in fuel economy. Useually within a week to week+half I'm at 1/4 tank. So I'll see.

I would reckon and change in fuel dilvery would decrease fuel economy, but don't hold me to that. I've always said the stock fuel pressure/delivery was poor, especially under hard acceleration my car (5 speed manual trans.) would accel. bog, accel. bog, accel. bog, then revvvvvvv off we go into what evers next usually 3rd.

I realide that my engin is a M10 and yours is either M42 or M44 (same diff I say) but do you think any of this would hold true for my 18-21 year old motor.

BladeRunner
01-09-2004, 03:26 PM
I thought the M42 was not the prefered motor to place a supercharger/turbocharger onto because of knocking, pinging, and possiblity detonation (or explotion), or is it certain years of the M42 are ok for FI.

---

ADD: Did anyone mintion a AMF/MAF swap any increase? I believe that if BMWs were equipped with the same intake design as the one on Supra's with a shield there would be a slightly noticable increase in power (minus the location because of water, snow, sleet, ice, etc.).

I'm not too familiar with the M10 motor. I just know it once produced an awesome 1200HP in a '83 formula 1 car. I know the M10 motor is very strong indeed. What's the compression ratio of the M10? The M42 is 10.5:1 I think, I forget.

Anyways, there is a popular supercharger kit for the M42/M44 which produces 175RWHP and it runs at around 7-8psi which is relatively low. This uses the Eaton blower with a kit designed by Downing Atlanta. It's true the M42 doens't like to be turbocharged. I've heard from people who have turbocharged the motor have run into a lot of problems.

The M42 motor was made to be revved. It's been used on the race track in BTCC for 3 years. It was the 2.0L S42 they called it, which was just a highly tunned M42 motor. Just before that they were using the S14 motor in their E36 chassis.

After reading some articles, I read that the M42 motor's technology was based on the 850 motor, I don't know how true this is, but that's what I read. I think the M10 and M42 motors are really quite different.

There was a long discussion about that MAF, it would seem it's a huge restriction on the M42 motor. A lot of people were talking about having custom ones made.

Fuel comsumption has dropped I have noticed. I would say it has almost doubled, but if gas in your area is cheaply priced who cares. I wouold say my sad 0-60 time has gone from 11sec I believe they say to 8-10secs (human counting here).

One more thing your engine will get a little hotter, which might be good for those of you drive your car likes its a M3, meaning you hit 5000+rpm freqeuntly. Moreover, the heater get hotter too.

It is ok during winter but in hot weather the wiring might melt
because of higher amps going

Knocking, pinging, and detonation has nothing to do with the engine itself. If the fuel delivery is not properly tuned any engine will ping, knock, and eventually melt a piston or two.

Moreover, m42 is a very good engine to turbo/supercharge because it has a forged crank. All you need is some low compression pistons and a couple more internal items here and there. Then 250rwh is easily archivable.
