Having had two E30 with E30 M3 suspension parts and S38B36(315HP) and S50B30(300ishHP) engines I could not agree more. E30 is a lot of fun, but the chassis of the 944 is way better, the engine however is terrible. I really miss the big straight six engines with ITB.

So you need to prove to the government that the 944 chassis can handle the power of an LS1?

Naturally aspirated LS1s, depending on tune, generally make 300-400hp (what do you plan for yours?). Not sure about 944s beyond 300hp, but Porsche built a lot of 924s (remember, 924 + fender flares = 944 ) with bigger and bigger turbochargers, all the way up to the Carrera GTP with 420 horsepower. Probably close enough for government work.

If you can install LS1 to 944, Norweigan laws are very free.No chance here in Finland, because too much CID in those engines
Also no possibility to install to E30 chassies engines you mentioned.

What exactly is the restriction?

in 944 world it is 3.0L + 20%, so 3.6L is the max for us. Also power can be increased max 20%, so legal max power is 250hp + 20% = 300hp. But most people does not care of these if engine is more or less original style what comes to visual inspection. LS-series engines are little bit difficult
I suppose our "big brother" is concerned of our safety. More free rules and young guys start to install bigger engines into their Rice-Rockets

So the rule is that the displacement of the engine must be no more than 20% larger than the largest engine available in the car, or it can't be registered or something? And same with the horsepower? Do they actually inspect such things (other than a look under the hood to see if you've replaced your four-banger with a V8)?

Olli Snellman

You figured it out correctly. The biggest engine in 944 world is 3.0L. You can add 20% more volume legally. The most powerful series vechile was 250hp 951. You can add 20% more hp. In certain cases local inspection can demand dyno figures if they feel there is more power. What comes to 2.5L=>3.0L turbo conversions they are not able to find out is there more volume or not, they are not familiar to the differencies of these blocks & heads.16V head is a little bit different story but most likely not a problem. So V8 does not pass visual check, they know these engines are far more bigger than original ones. V8's are allowed if they full fill 20% rule, just give me a 3.6L LS-series engine

If I lived in Finland I'd run nothing but turbo cars...oh, you want this dyno'd? Sure, let me turn this manual boost controller here a little bit. Yes sir, 2psi is all the turbo puts out. I know it's a little slow but I like to be safe!

JDS968

If displacement is the limiting factor, you want DOHC, not pushrod! 3.6L 32v V8 from the Audi V8. Twin turbocharge that one, you'll have a beast!

*roflmao*

Seems like it's always easy to make a car produce less power than it can, for inspection purposes...turbo or not. Why do they even bother?

Olli Snellman

I suppose Audi unit would be nice, but most likely it's just too wide. So engine room needs to be modified heavily. Also there is a price factor, even here in Finland we can get LS-series engines far more cheaper price compared to Audi unit. In BMW world here they install BMW V8's to E30 bodies, here's one of the nicest examples.

Jando-Porsche 944 Turbo 1990, 300hk got some reviews in 1990

Wide I'm sure, but I thought we were talking 3.6L maximum displacement? There is no LS series engine near that, the smallest they can be had is 4.8L. I think it would fit though, so long as you're willing to relocate the master cylinder and brake booster, and maybe notch a few inches of firewall (or space the whole thing an inch or two forward)...does anybody have specs on it?

BMW V8s are very nice though...and the 3.5L M62 would be within the 944's displacement limit as well

DMV is on our case with all this, our DMV doesnt care about engine volume, only power, but the power numbers has to be FACTORY,so we cant detune it.

we found a LS based engine down to 270hp in 4.8liter and 290 in 5.3 alu, that might be doable, especially if we could just find a tuv approved chip, for a turbo S, that would help soooo much!

At least when your Government is concerned with your safety, they make sure you know how to drive before allowing you to do so on public roadways. Here, they teach you how to cover your eyes and hope. I swear, a driver's license in the US is just like beer... "You can't have any until you're old enough... oh, you are old enough? well then here, have all you want" And it's obvious on the road... the vast majority of the people out there have no idea what they're doing. But it's not really their fault, our Govt. gave them a license and told them it was ok to drive. I just don't get it... because you can pass a written test that basically asks you to read road signs and define their meaning, and a driving test which requires you to drive at a constant speed, then stop, back around a corner, and then parallel park, you're qualified to operate heavy machinery around a bunch of other people doing the same things with equivalently terrible training? And then, you take these tests ONCE when you're 16years old and then you're good for life? And then getting wildly drunk and driving around MIGHT get your driving privileges revoked, for a while? I think trying to merge with an 60-70mph interstate highway at 35mph should result in loss of privileges... but no, people do it all the time. Our department of licensing might as well be a vending machine.

Sorry, that wasn't intended to be a rant... but I just got going....
