i have a stock 924 auto and i want to 'up' the power output by about 40%(ish).

i have seen a header by msds that boasts of a 14% minimun increase! is this true/worth the money/ etc.?

does anyone know where i can get a franco gear set (haven't a clue what they are but applebit recons that they're good! )

i would also like to change to twin weber dcoes (either 40's or 45's). should i change to them or should i stick the mech. injection? if i should does anyone know where i can get an inlet manifold to fit them from?

one more question! ;o)
will i need to make any mods to the tranny when i increase the power or will it be ok as stock?

I would KEEP the automatic tranny. They're great.

Headers will work. Just watch the heat and cracking.

Franco cam gear gets very good reports.

Port and polish the head if you get a chance. I've done it and it worked for me.

A good electronic ignition would help.


If I lived in England with the weather you folks have, I would definitely NOT go with Webers. You'll be tuning it up more than driving it. The stock fuel system is adequate for your goals.

where can i get a "franco cam gear"?

also would it be worth while changing the cam? if so what sort of lift/duration?

Hi Matty,

Franco cam gear is at :-
Franco Industries
Attn: George Franco
6693 Alcala Knolls Dr.
San Diego, CA 92111
(619) 292-7949"
dunno if there's a web address - maybe someone else does ?

As for Camshaft, there's another thread on this part of the board titled 'Performace Camshaft and Camgear' - gives a lot of information. Also buy last months '911 & Porsche world' magazine its got a good article about fitting a piper Cam to a 924. You can get this magazine in most large WHSmiths in the UK.

A Word of warning though - be careful with hot cams and auto transmissions - they don't always make ideal partners.

Matty- first question: How much money are you willing to throw into this go-fast project?

BTW: The area code for Franco Industries is 858 not 619 (not posted correctly)

Go to my website and go to links. Go to business links and Franco Industries is at the bottom of the page... let me know if you can't find it.

Matty- I would seriously recommend a Franco cam gear along with an electromotive DIS system. Then along with this purchase an Integral Cam stage 2 and if possible a port & polish and headers. Yes, you are talking $2000 but I have a computer-ized theory of the 924 getting to 60 MPH in the mid 7 second range! No joke.

Anyone who wants to put an electromotive DIS system on their car- I can help them with all the details as well.

Just remember, you're talking with a guy who has his 924 getting to 60 MPH in high 5 second range right now... going to get an Integral Cam stage 2 cam in my car next and... well, I have to still input the data and figure my 0-60 MPH times... but I am sure it will be a Boxster S killer...

Anyhow, look forward to talking to ya again...

(I could have put a new Z28 tag on my car... . read my post about Franco cam gears and you'll understand)

P.S. don't get carbs... no extra power unless you do major mods... and then I know a better solution for the money than carbs...

I know tricks to make your CIS injection system 25% more effective!

(I have got to update my website guys... there is so many valueable pieces of information that I have not posted it is incredible)

If you're going to go to that level, it would be a good idea to get a 931 cylinder head, and P&P that, to go with your hot cam.

Of course, a 931 head will drop your compression by 2 points or so, right? The 87 and 88 944s had the same 100mm bore, and 10.2 to one compression.... Or you could get a stroker kit, good for 300ccs or so... Comes with custom pistons in your choice of compression, and you can always sell your old parts to offset the cost.

are the 924 cam gears the same as a vw water cooler?

[coconutcowboy]

Is the 924 2 litre cam gear the same as the vw water cooler.

sorry to get off the subject,

also will I get more power using a 80 02 sensor downpipe mated to a 924 primary muffler and behind that use the 944 exhaust sysem. do 944's have a resonator?

Will a 968, 944s, 944 turbo 6 blade fan and motor fit on both sides of my 924 dual fan shroud or can I use the 944 dual fan shroud from an early 944?

sorry to get off the subject again.

I was also thinking to take the load off of the fan thermal switch by using cooling fan relay and some wiring from a eek!!! chevy celeb.

was going to use the switch on the ground side and connect the hot side of the relay coil to the battery directly as well as the connecting one side of the switch contacts to
the battery and run the ground side of the switch to the fans and then to ground.The relays are only $12 usd

was going to use a power tap block and fuse holder as used for high power car audio amps to make the connections to power.

Any thoughts

coconut, why reinvent the wheel? if it is there and it works perfectly fine why reinvent it? the way your talking about doing it would make a simple task more complex, and with more complexities comes more things to fail. I'd say don't bother just leave the fan switch alone.

[Cbass]

Coconut, if you are going to all that wiring trouble, start from scratch. Find out how big of a motor you will need, and find the biggest prop you will be alble to fit in the space. Good luck

[coconutcowboy]

The original fan wiring was hacked all up and so was the fan shroud(cut in half and a vw rabbit motor and fan installed. The thermoswitch was bypassed and the fan wired to the ignition circuit.

This car came from a sheriffs auction from a chop shop operation.

Will the stock switch handle the two fansmy car is supposed to have or is one wired to the switch and the other to the ac

Sean?

Buy the Piper Cam, and Timing Gear. That way you have no problem with shipping and import duties. L242 for the cam and L91 for the cam gear.

Piper Cams, Sevington, Kent, the phone number is 01233 500300.

Dump the automatic transmission and get back the 20% of the engine hp that the transmission is sucking up.

When the rubber dampener located in the would have been the clutch housing dies, the replacement part cost is $700-$1000, plus labor. You should be able to do a five speed conversion for less than that.

Coconut, if you need a fan setup and shroud let me know, i also have the wiring harness for it.
