2001 porsche 996 ls1 conversion
#201
I've bought quite a few parts from LAPD (Sun Valley, CA). I have dealt with the owner rather than his crew, and he has always been very accomodating, honest, and concerned for your satisfaction with the transaction.

996 ls1
Very cool thread, this type of conversion takes a lot of brain power, good to see you are keeping on it. Reminds me of a 914 conversion I did with an alum 355 Chevy several years ago, not a sleeper with the Crower inj sticking up behind the window and 930 rims with box flairs, used a 911 trans to hold the power without breakage. Fun fast and unusual, I like it.

Nothing much to report ,
i'm just waiting for the next batch of parts to show up. i ordered a magnaflow muffler PN12469 with dual inlets and outlets , the muffler is kind of an "x" design inside but without the pipes actually opening into each other . this would be the muffler that sits infront of the balancer where the original stock muffler used to be.
another thing i ordered is a couple of mufflers from extreme mufflers , these are "U" mufflers that have both inlet and exit on the same side.
http://www.extrememufflers.com/index...p_image&pID=54'
these mufflers will be on both sides of the engine and will flow into the "x" muffler.
also ordered an engine harness, and drive shaft for the tranny, coolant expansion tank , exhaust flex coupler, as well as the missing brake caliper and emergency brake parts. and i should get the exhaust flanges from the machine shop tomorow .
the oil pan has been shipped as well
untill then , i guess all i can do is cut the brace and start routing some wires and hoses.

I know the motor mounts and tranny placement have gone through a few iterations, so I am not sure if this has been addressed or not.
Do you think that with the current forward tranny placement and LS4 accessory drive, you could fit the engine without having to cut the brace? Also, if cutting the brace is a necessity, are you going to box in the notch to enhance its strength?
One last thing, do you know if the standard 996 transmission has that same removable pad mount on the bottom?

Great questions derek, if i used an LS4 accessory drive and and the CURRENT trans placement i would still have to cut the brace . now if i made a custom transmission mount and worked around the coolant hoses , shortened the drive shaft , and cut and rewelded the shifter arm then an LS3 accesory drive would work without cutting the brace.
my problem with redoing the trans mount is that it was alot of little hassles to deal with , along with the added CV angle. another consideration is that we don't have any cars with LS4 accessory drives over here. so an LS2/3 would be more practical now and later down the road.
and yes i do intedn on either building a new brace to strengthen the part i cut out , or just using GT2 bumper mounts which are solid peices that will attatch to the stock alu. bumper making it a rigid brace.
another thing to consider is the adapter plate and oil pan clearance with regard to the suspension crossmember . setting the trans closer towards the center of the car means you have to cut the adapter from the bottom (like i did ) and notch the oil pan or get a flat drysump pan.
as for the standard 996 tranny i don't think it has the pad ( look at the first trans in the link) :
http://www.californiamotorsports.net...oxster%20S.htm
but a GT2 tranny is basically the same trans as the one i have but 2wd. but if you ask me , the standard 996 trans is alot easier to fab a mount for.
now, if i was building a race car with rwd anstead of AWD then i might do things a bit differently; the trans would probably be shoved as far forward as possible and a new mount made and the engine would be sitting alot forward than it is now to get the best weight distribution possible regardless of comfort or longevity of parts.
heck , if you are only going to run an alternator and a remote pump , you can get away with not cutting the brace at all or maybe notching it only.
any how , i managed to cut the brace out and test fitted everything from the accesory drive , and they fit !
i just have to sort out the power steering pump since it will mount on the motor plate and will be offset a bit.
sorry but no pics since i didn't get my camera with me

Here a couple of cell pics ( sorry for the quality ) of what i did last night :
will get better ones soon
on a side note , found out that a stock F-body alternator will not work with an ls3 alternator mount.

I think the LS4 accessory drive would only be worthwhile if you didn't have to cut the brace. The high mounted alternator is kind of a turnoff, so unless the LS4 would fit without altering the car, it is pretty much a non starter.
Great project and keep up the good work. Always look forward to updates.
BTW: Seeing that intake manifold on there makes me dream of seeing a nice cross feed ITB intake with a massive airbox fed by the rear spoiler.

sorry for the lack of updates , but i've been busy andout or town , plus i've been waiting for the batch of parts i ordered to show up.
here's what i did so far:
i cut the brace and welded patch panels to close the holes , i also found out that the muffler i ordered (magnaflow p/n 12469 ) is not the design i was thinking it was : apparently it was dual inlets aand outlets that merged in the center of the muffler , i was hoping that it would be two seperate paths that crossed in an x pattern but did not open up on each other.
any how here are some of the parts that already showed up :
and here is the ultra sexy kevko oil pan and integrated baffeling :
EVOms GT2 clutch hydraulics conversion :
and here is how the brace looks like after cutting and welding the patches:
like i said i'm still waiting on some parts to show up like the harness and extreme racing mufflers and the GT2 solid bumper braces so i can begin fabbing up the exhaust and brace reinforcement and the rest of the brake parts . i'm also am waiting for the driveshaft to show up along with some other things here and there
so as for now , all i can do is build up the mid mounts ( between the engine and trans - to help support the two just like a mid plate) as well as route a few hoses here and there. after that i should start thinking of where and how to route the LS1 wiring harness and clean up the existing wiring in the engine compartment.
