Well, look at your engine... On the rotorhousings it says "12A" or "13B"... Also, if it has a blue airfilter canister, it's likely to be a 12A, if it has a intake plenum reading "EFI" or "Fuel Injection", it's probable 13B.
But shouldn't it say on the paperwork? Like 2.3 or 2.6 liters?

if yours is a GLS, chances are it's a 12a.

12As look like this:



13Bs look like this:



as to what you can do to beef it up, first thing I'd suggest (once you figure out what size engine is actually in there) is a Racing Beat exhaust system (huge HP gains) and a K&N air filter (far less HP gain for far less cost, but better throttle response)

If it was a carbureted 4-port 13B, it would probably also have a blue air cleaner.
But, the rotor housings will be marked as our friend in Belgium stated.
I think if it was a 13B, you would probably not be in such a hurry to try to "beef it up".
Anyway, welcome to the forum! -WG

1.1L = 12A
1.3L = 13B

Ok, that's how the you guys do that... Sorry, I just assumed that the US and/or Canadian goverrnements were just as fucked up criminals as ours are. those idiots double the capacity of a rotary (hence my 2.3 and 2.6) to make sure I'll pay WAY more taxes.
So, they are ripping me of, stealing my money, so they can afford themselfs a stupid Mercedes S with driver. **** them...

They say it's a 2.3 or a 2.6??

I'm glad I'm in Canada, and somewhere with no Aircare

The Society of Automotive Engineers (SAE) standards list them at 1.1 and 1.3 litres respectively, but I think (please correct me if I'm wrong) that Europe goes by DIN instead

You are very right. But that doesn't matter actually. Germany says: no cilinders=no cilinder displacement. So very cheap taxes... Holland goes for the weight, but calls them 1.1 and 1.3l engines. Belgium thinks you can never pay enough taxes, so they say it's a 2.3 or 2.6. Making $375 or $500 the annual road tax. If you have an FD, they make that $1100. (extra tax 'cause your car is TOO powerfull...)

Sounds similar to Japan.

Yea it does. Don't they have a 280hp limit on production cars in japan too?
BTW, its GSL, no GLS, not like it really matter cause we all know what your talking about. Just thought I'd throw that in there.

As far as I know that's a sort of volentary limit (not sure though)
As for Belgium, we also have a tax on buying a second hand car. Every time a car gets a new license plate, this tax must be payed. They just increased it a bit... My friend bought an FD, last year a 10 year 240hp (european FD=240hp) car was $60 tax, now that's $ 1200!!! He didn't like that...
All I can say is: there is a eason why politicians are called powerhungry, corrupt bastards overhere. As far as I'm concerned, they can crash a plane in there.

Wow, this exhaust sounds interesting. I have a 12a motor also on my 83 GSL and I was wondering how much HP gains I would get with this exhaust system? Where can I purchase this exhaust system? I live in CA so the smog regulations are STRICT (my 83 GSL has 2 months to pass smog right now ) so how would this affect my smog test with an exhaust system like this? Sweet, thanks.

er... I don't think it's smog-legal... but my Cali buddies use header exhausts, then swap in the stock stuff for testing, then swap back to headers etc.

Seems to be a pain in the patootie to me. Having Saskie plates on her, Pamela doesn't need to do the annual blow test

you can get the exhaust system directly from Racing Beat.
