Hey everyone, I currently have a 318is E36, with some minor details done, most on the body....however I have not yet at all attempted to do much under the hood. I have only installed a cold air intake. I am not loaded like some guys, so Please try to keep the engine swaps to a M3 engine to a minimum because I doubt that will happen. Its the 4cyl. engine and i'm at 140hp, I'm not wanted something crazy like 300 but it would be nice to be able to get an extra 50+ horses. If anyone is good with performance mods that won't cause me to sell me house and live in my bmw please post. Let me what upgrades you think I should do on this virgin. I am open to opions, as long as they don't end up costing me to repair.......thanks for your input guys.

50horses? ur gonna have to go with DASC or something i think..im not familiar with the M42 motor..but KIRASIR has a turbo 318 and daydream M3 had a supercharged 318is

Its a M44 engine, however like a said i am a newbie so I don't know what you mean by obc1 and obc2....now in response to the chip. Is that really a safe thing to do, I heard that people who put that in, screwed up there on board computer and it cost them about 150 to have bmw reset everything. What kind of performance can I gain with a chip?? also you had mentioned a supercharger/turbo, where would i be able to get one of these things without breaking the bank??????

1) Forget about a chip for your car - waste of money

2) Forget about CAI, exhaust, cams, larger tb, software - waste of money

3) You have 2 options:

a) sell the car and buy 325/328 or
b) get DASC(Downing Atlanta SuperCharger) www.downingatlanta.com

It's about 3200US. So start saving.

I agree with KIRASIR. However, if you can find parts cheap, possibly used I would consider doing the basics (intake, exhaust, chip, TB), it made quite a noticeable improvement on my car. If you paid full price for these basic modifications you might as well get the supercharger. It will give you around 220 at the crank (175HP@ the wheels).

For OBD2, computer reprogramming is useless and a waste of money. The only time you would need such a thing is if you had a really hard tuned engine.

Exhaust won't give you power but might move it around your rpm band a bit
Chip will bump up your redline so you can blow your engine
Cold air intake unless done properly will act as a "hot air intake" ..but it sounds nice
DASC supercharger will give you much more power and actually is a good deal, but don't expect to win races against any m3's
Rear end gearing.. will give you better 1/4 mile times.. but you loose driveability

What i did to my M42? rebuilt motor because it was worn out (only 150,000 km's) kept everything stock except some head work. didn't gain any power, but it runs nice. I learned that's about all i can expect from the M42/M44 unless i spend atleast $8000 tuneing the engine and drivetrain.

Your motor as a knock sensor unlike mine so you can play with it a little more and not have to worry. you could try getting your Cam timeing adjusted to optimize the engine slightly, if it feels like it's lugging.



Good luck

I guess I will just stick with what I have, pamper her, then get into a 330ci, I have looked up 1/4mile times and the E46 330ci and E36 M3 are pretty close, a few engine mods on the 330 and I will be there....The problem is finding a 330 ci for a good price and selling my 318is for a good price and not giving it away.

Increasing the rev. limit 300 rpm or so will not be the cause of an engine failure, especially in a small 4 cylinder like this one.

If you put a chip in your M42 you would notice an improvement and it wouldn't cost much. You can gain around 13 hp from a chip in your car.

(the original poster can't use a chip as he has OBD-II )

This is the only thing I'm planning for my motor:

1. Chip
2. Differential

MarkD, you sell chips, right? Do you remap the software or make custom chips?.. how much hp can I gain (I have a M42)

See my post previous to yours for the where I mentioned a 13 hp gain.

I'm not sure exactly what you mean by re-map or make custom chips - Yes I remap the existing timing and fuel maps, I also make custom chips on occasion but I don't like making customes as it takes a lot of time and most people don't want to pay extra!

In the last year the some of custom chips have been for an E30 M3 used as a club racer, an M6 with different cams, and now another E30 M3 in the USA with many changes. But these chips are expensive to develop.

Oh, I see. If you don't make any, what kind of chip would you reccomend? (Something I could get locally?)

I will probably stick with what I got then, After hearing the facts. Hopefully when the new 3 series comes out, i'll be able to scoop up a 330ci and mod it to hell.:cool:

Sorry if I wasn't clear... I do make a chip for your car. Send me an email at: mark@dsylva-tech.ca and we can discuss it further. Or call me at the number shown on the CONTACTS page of my site.

Thanks

3:91 makes the m44 alot of fun even in stock form.

You should try 4.44. It's no challenge breaking the rear wheel's traction. Ask me how I know ;)

Gavin (daydream) said he had one, and he was hittling redline at 120 km/h

3:91 need around 3g's to consider breaking the rear loose, but past 4g's can burn the tires off (both), can image how easy it would be with a 4:44 and impraticle for a daily driver.

LOL, it's not that bad. I topped around 160-170 before hitting redline. At 110-120ish in 5th gear, it would do around 3800-4000rpm. However, even so, still very impractical. Well suited for Auto-x and very short circuts. The fun thing is on a short track like Shannonvilles Fabi, I barely ever had to downshift. Kept it in 3rd most of the time.

Funny minein 5th at 110kph is at 3800 ish rpm, 120 4000 rpm, 130 4200ish rpm & 190kph 5800ish rpm, it is governed @ 190 but still not at red line.
Think your buddy had a 3:91 diff not the 4:44 or was this in a e30 with a .89 final drive unlike a E36's 1:1 5th gear?

We're talking about 318's here correct? The 4.44 was taken straight out of an Auto E36 318. It's the only Bimmer you can get that diff from. I topped out at 160-170, and I doubt the governer is at 190. I've hit over 200 in a stock 318 before w/o any chipping. Mine was an M42 if that makes any difference. OBD1 vs. OBD2 basically. I think you get a bit more torque from the 1.9 is it? I forget.

Thats crazy Bry, I mean the 4.44 is so insanely short, if it's really as you describe it, at 120 it's 4000 RPM?? Thats only 500 RPM more than stock diff. So it doesnt look that bad for a daily driver (obviously not a highway cruiser).

jeffrie
01-18-2006, 07:47 PM
e36 318is yes, which I drive daily so I know the RPM's @ speed are correct. OBDII 190kph top speed and just stays their, before the diff swap was 195 but speedo was the one that was out of spec then (new diff new sender). Old 3:45 diff was all reving 500rpms less @ speed then the new one. Thinking the speedo was out on the 318 you were driving which may be why were both cunfused.
I would think with a 4:44 160kph would be my top speed RPM wise.

Yeah but that's only the final drive. The first 4 gears go by like nothing. It's more like 4500RPM at 120 and 4000 at 110. I forget since that was my car almost 4 years ago, hard to keep track. At any rate, 500RPM means a lot, especially when you top out at 160. I noticed a difference of about 800-1000rpm's at highway speeds, but anyway, you can't compare the gears like that. All the gears are different ratios and they won't be consistantly 500RPM higher than with stock gears. Like I said, the first 4 gears are REALLY short. Highway driving is OK. Try keeping up with quicker traffic at 130-140 constantly. It's nearly impossible without serious wear on the motor.

Well I've owned 2 different 318s. A '92 with stock ratios, then with a 4.44 from an auto, then a '94 with stock ratios. I know the top speed is around 160-170. I've tested it numerous times. I've driven these cars for 4 years and I'm 110% sure that I had a 4.44. I just noticed that you're from the UK. I don't know if you guys have a different top speed limiter. But all E36's here are limited to around 220.

Lol, I'm from Buckingham Qubec Canada (north of Ottawa, it's sh*t hole, no surprised you mixed it up with a place on the other side of the pond).

You had 2 M42 OBDI 1.8L 4 cyd 318's.
Mine is a 97 M44 OBDII 1.9L 4 banger. Geuss the older 4 were alot faster then the newer ones, much easier to chip too (wish I could) and looks like they had no govenors.

Jeff is actually a half hour outside of Ottawa...lol....yeah for some reason his 97 M44 is governed at 190km....My 94 M42 goes around 208-210km/h at redline...I smoke Jeff on long(straight) runs lol.....

I'd get you guys numbers for 110km/h (It was usually 20km/h for every 500rpm in 5th past 100km/h)and so on but I haven't driving my car in about 3 months....man I can't wait till spring....

And no I'm not putting any $$ into performance...at the rate M3's are going for especially E36's....I'll get one of those instead.....Or an E46 depending on cash flow....

The only mods worth spending money on for a 318 are suspension and weight reduction. Anything else produces very marginal gains. Get the weight down to around 2500-2600lbs and the car is pretty quick and handles like nothing else. The LTW M3 flywheel is amazing for the 318, it actually renewed my joy of driving it. Although not too powerful, there's something about a lightweight, rev happy car that's very appealing.

The best way to gain power for this type of engine is going FI. Turbo would be the better choice.
