my 2.0 lives between 5000 and 7000 nearly all stage. It just has crap for torque below that.

Yep they do have a good rep..
Now being a long term engine builder and having seen PIKLES of flow sheets for the motors we muck around with AND keeping in mind the "pretty damn good" rule-of-thumb that "max valve lift= 1/4 of valve diameter"......

I sure as hell see very little point of cams with valve lift into crazy degree when flow charts show a flattening out of flow at oh say 11.5mm for something with 44mm valves.

in other words let's say a head is flowing 220 cfm @ 10.5, then 223 @ 11, then 226 at 11.5, and then 228 @12 and maybe 234 @13mm

For a piddly few more cfm we have huge packaging problems: valve spring may not have the travel, spring rates start being hard to do and even lobe to head interference or bucket diamter is too small and cam lobe rams into the side of the bucket...all kinds of problems for a 1-2-3% increase in flow...

Rum, very rum some of these crazy lift designs...

Oh and BLOOODY PRICEY they are too .

That price is what led to me making these (under contract for a specialist Volvo shop)




Here's some completed:


Here's a nice side by side of a stock Volvo cam and a common Swedish rally oriented profile:


Nice, eh?

I'd surspect that its one of those things where peaking at most lift than necessary means, if you can have stuff tolerate opening that far, the valve is open past 11mm (or whatever) longerer. If you have a valvetrain that can tolerate opening that fast, I bet that the nose curve is easier on things doing that then it would be doing like some circle track cams with limited lift do and holding at a constant lift for a while.

Now I kinda want to do some simulation though, for shits and grins. Not like cam profiles are relevant to a rotary powered rally car. winking smiley

They are not the most expensive but they do cover a pretty broad range of vehicles. Obviously if there is the demand for you to get a batch made like you have done then that makes sense. It's impressive to see such commitment in doing that.
But possibly just for the one off purchase then sometimes it is less hassle to just bite the bullet. I noticed they did offer cams for the BMW 1.8 M42 and 1.9 M44 engines so posted the link as it was relevant to this thread.

I mentioned the 14.5mm lift with an eye popping smiley merely to show they do produce things that are a little out there. That cam may be for a very specific application such as hotrod or other restricted class. It's certainly not for me with all the extra grief it would bring that is for sure.

Actually, 14mm for a Rabbit head, wonder if that's intended for the old Formula SuperVee cars. Pro class back in the day too, so probably completely willing to look at valve springs as a wear item.

This butthurt guy really needs to find something better to do with his time. So far my interaction with everyone on the site is fine.

sometimes i miss my 325IS. Didnt like the steering very much, and was nose heavy feeling, but overall was enjoyable as a car.

Im not at a competition level but the 4cyl car feels good, probably a little nose heavy but dam is it fun to drive! your right!

As for the Picture IM BONED on clearance I really thought it was gonna be more, John V maybe I can run a shorter spring from your collection? As for the struts I havnt gotten those out of my other e30 yet but I would have no problem sending them away and matching them to THE BEST spring I can fit in my area, I dont see it being a problem as the Bilstein HQ is local and they rebuild them with a valving of your choice if you know what to pick. Another guy mentioned "rally" to them and they said they knew just what to build them up to... But never said what spring to run so thats pretty much useless. The car never got driven to my knowledge so we dont know how it all worked out. ANYWAYS!

A couple responses to earlier threads.
The car is very high but only because it has a Double stacked strut top hat to gain ground clearance and still has noticeable droop. Even thought Im picking serious rally guys brains the car is used on more of a "pre runner" or "fun car". Love me hate, at least im not in a pickup.
My clearance problem is now an issue and I might get a low offset wheel and gusset up the strut so incase I do get some clearance a bent spindle will have a harder time rubbing the tire on the spring.
Anyways thanks for the help and hopefully I can get this semi assembled.

Re: Cars good, idea on suspension improvement.

I know this thread is dealing with suspension mostly, but with all the talk of motors, I thought I'd throw in my 2 cents.

When getting started on my Compact project, my target was 220-250hp.

Did some reading seemed like the S14 would be perfect...until I priced them out. $5-8k in the US for one that's leaking from every seal. Then add in the costs of getting it rebuilt and that option was off the table.

Did some searching on modifying the stock 1.9L engine that came in the 318 model cars. That too was a no-go when I realized how much people charge to work on these motors. Once again, $5k plus for a rebuild an you're still not likely to be anywhere near 200hp.

Finally started looking at the 6-cyl engines. 2.5L motors can be had for $200-500 at local wrecking yards and from people parting out cars on Craigslist. Willing to drop $3k and you can find several 100-150k mile M3 motor/trans/wiring swaps on the message boards. Want 330hp N/A? Get one of the early 2000s M3 engines or source any of the Euro 3.2 engines from 1996 on. Prices for those are back into the stratosphere with most running in the $7500 and up range.

Since my car was an automatic and I know how out of control getting an engine built can get (see: 700hp Evo motor...gahhhh!), so I decided I'd simply buy the engine that would give me the power I wanted right out of the box in a reliable from-the-factory package. Of course it turned out that the 1995 engines built January-October had one little flaw in them (soft retainers) .

Yes, the 6-cyl engine weighs 100 lbs more than the 4-cyl and the weight is in the absolute wrong spot, but that's a reasonable compromise IMO for a privateer building a rally car. All these 'cheapish goodish oldish' cars have their faults, just pick the one you can live with and go slidewayz in the woods. smiling smiley

Yes, sideways in the woods is best, as opposed to straight on into the rocks!!

Could be a donor car here, but it looks like this big 6 in the M3 suffers from chronic understeer (by the driver). smiling smiley

Probably better that he went straight off considering how well that seat belt appeared to be holding him in place. LOL

Wonder if he had an anti-sub belt?
