heres the proof and clencher.

look at the right of photo showing tranny attachment. looking at front of motor the intake is on the right ala 924.

also you are veiwing the engine from the front of the car.

stand next to your 924 cars open engine bay on the drivers side looking in and your timing belt will also be on the left and the intake side facing you. tranny to the left.

gotta get that engine.

What is the point in doing that engine swap? Better off just doing high comp pistons and make more power then that engine and you would spend a lot less.

put the 16 VALVE HEAD on a vw rabbit/ AUDI type 2 litre stretched vw rabbit block and go with a good set of cams, valves p@p and a good exhaust.

PARTS ARE MORE READILY AVAILABLE. more so than our 2 litre engines.

engines have knock sensors and run up to 10:1 cr NA and mega boost on turbo's and intercoolers. and YOU GET EFI in the deal.

No more bastardized and cobbled up efi systems

all sorts of oil baffles and cam savers baffles and intakes. also custom distributers, eproms, throttle bodies you name it.

Yopu guys need to look outside of the box.

this conversion makes alot more sense than a rover/buick or chevy v6/v8 conversion.

and a hell of a lot better fit than some of the 5 cylinder conversions talked about.

More whole dollars worth.

i believe applebit dropped 10:1 compression pistons in his car. Also how much would this engine mess up the weight balance?

It shouldn't be heavier and you can still use your mostly stock ac system.

If the engine is heavier than desired get an alloy flywheel and a optima battery and a liteweight hi torque starter and a smaller high output altenator.

if the engine is already lighter then you should take out weight from the rear by use a rear eurobumper and or a lexan hatch in the rear or move the battery to the rear of the car.

As far as weight goes it should be close to the same or less than our current engines.

ok just listen to the amount of money this will cost. Then think of how much it will cost you to upgrade the existing engine. It is completely not worth it.

I didn't know that owning or fixing up a Porsche was all about the money.

I thought It was a hobby and a passion for cars.

Not a Business.

Besides I will be looking for a 16 valve head to go with my GTI rods.

And the foreign car friends of mine doing honda's are giving practically away their old rabbit, scirroco's and parts.

Be sure and let us know how this swap goes, should you decide to do it.

I know a place in Montreal that sells Nissan CA18DET engines for $900...

DOHC EFI turbocharged 1.8 liter inline 4 cylinder... I'd say that's the best swap, dollarwise... just have to figure out a way to get the clutch to mate the engine and the driveshaft...

our engines are good only after a good port and polish of the head and then to get any real power we need to a upgrade to a turbo or modify the NA engine with a turbo head.

My whole point on this is that out of the box stock we already have a hp gain.

couple that with a tb on the 16v engine (which does nothing on our cars until the head restrictions are removed) and cold air induction and freeflow filter and you have made some modest gains. (ditto for these mods also).

next would be a set of cams (easy to get new, no regrinds and cheaper priced) and cheaper priced easier to get cam followers (some are even hydraulic) and a free flow exhaust for even more power. (with a 924 you would have to port and polish the head to get anything with these mods at all and bigger expensive custom valves to get any real gains)

and all the while you are getting a factory vw/ audi EFI (which you can get chips for to increaase HP) and a higher revving engine and 16 valves to boot.

to get new lifters we pay roughly $75 to $85 each, $200 - $300 usd for a reground cam to get more hp from the motor.

more power can be had by custom one off pistons at or around $550 to $650 usd and custom bigger valves and a port and polish for big bucks. you can even bore and stroke the motor ($1200 plus usd with a welded up crank)

with the 16 v engine you can go for even more power by using the rabbit type Audi 2.0L block (not Porsche 924 type) to get even more gains.

all this using a stock crank and rods and pistons (no modifying or bastardizing the engine) so parts are easier to order should you decide to take a road trip and need something

bolt on goodies for this engine are abundant as are inexpensive and abundant spares (compared to Porsche 924) such as heads , blocks and cranks and rods and pistons.

try that with a 924 engine.

what I am saying is no haltechs, mega squirts or cobbled up efi / cis from obscure parts to be tracked down from other vehicles systems.

no custom one off trick parts (other than mounts, oil pan and exhaust) or using trick machining inside of the engine.

easier to get and cheaper to get parts both at tuneup repair or overhaul time.

some of you guys are good at fabbing stuff for your personal needs.

It shouldn't be hard to install one of these engines since someone out there already has done the audi 5000 engine. its basically a rabbit engine with one extra cylinder.

we could probably use some of his diagrams to simplify our process of installing this engine and besides it would be fun to run the 16v engine in 2 litre form in a 924 or carrera gt replica in the 2 litre class races.

and a complete 16v engine can be had and built for power less than the stroker 924 engine could be built and more reliable.

and you don't have to run a rice burner engine or some off lineage engine with bellhousing adapters, custom flywheels and clutches and linkages.

I am sure Porsche would have considered this engine had it not gone to the 944 instead. after all i am sure VW /Audi used some of Porsches data to come up with the 16v engine.

I have stated my case.

you guys are missing the point. AGAIN.

Sure there is some fabbing and fitting to do. BUT you guys are willing to install a cam on a stock system after sometimes removing the head to PORT and POLISH (alot of detail work and hours too) not to mention the work removing the HEAD., intake and exhaust maifolds and all the CIS stuff to get out of the way just to do that.

all that work when you can do the VW 16v conversion and get some results without REMOVING the HEAD. or any parts to change even. the 16v engine already has a hp advantage and power to weight ratio advantage over the 924 2 litre NA engine and an infiniteley better flowing head for adding other mods as well.

this engine readily responds to external mods and even more so to a set of cams which are just as easily installed on the 16v as our engines.

Put it this way to get the same gains you would need not only to port and polish the head but you would also need to go to bigger custom made valves to boot. and don't even start into matching the compression ratio yet.

custom pistons for the 924 engine cost lots of money.

and beyond that you would have to bore and stroke the engine and / or make a hybrid engine using a turbo head on an NA engine for the better flow through the turbo head. that requires fabbing up custom headers

now lets see which is engine cheaper in the long term in the scheme of things?

add up the dollars it would take to get close to the performance figures of a good prepped basically stock 16V engine on a 1.8 block let alone a one based on the 2.0 litre "big block".

and for you turbo guys out there 16 valve engines have turbo systems readily available and plenty of boost controllers and a safer engine thanks to the knock sensor in the engine management system.
