so what to do? A new 3.4 or maybe (dare I say) and LS1 swap?

 

I had mine rebuilt for $4400 in Austin TX. I even upgraded to all ARP bolts studs and better bearings.. LNE cam paddles, new chains/LNE guides and LNE IMS bearing....

I paid a total of $5500 installed 6 month 12k warranty! I have 10k miles on the rebuild and couldt be happier.

Im sure with as many guys on this board, we can find you a place to allow your wallet to take a break!

Good luck!

 

Interesting Sergio.

As far as I know there are not aftermarket main/rod bearings available (yet).

On your rebuild was there any treatment of the cylinders, or did they just reuse your existing pistons and just re-ring them. If so, did they measure bore/taper for wear and was it within the acceptable limits?

Also you said that LN supplied paddles and guides, but do you mean the main billet tensioner? I don't see any other guides or ramps in their catalog other than the main IMS tensioner paddle.

 

I'm not sure about this, but i remember reading a thread previously about the swap only requiring some retuning (that's possibly a 3.6 to 3.8 swap, not 3.4 to 3.8) so that might alleviate some of the DME, harness, and rewire.. but i'm not certain.

As for the airbox, if the 997 airbox fits the 996.. would the reverse be true? for that matter, i've seen people install a K&N FIPK 996 intake into a 997 (albeit a 3.6).

As for the exhaust, as per this thread; https://www.6speedonline.com/forums/...t-headers.html fabspeed implies that the headers on the 996 and 997 are the same, also their catalytic converters are interchangeable, so i'm not sure why you'd need a new exhaust?

 

gray,

I thought the same about the bearings.... but when my mechanic asked me if i wanted the standard or "better" bearings, I assumed there was an aftermarket. I took the time to research my invoice for you and found that the cam paddles are stock and LN supplied the main IMS tensioner paddle as you stated.

The block was "x-rayed" and found to have no cracks and did not need to sleeve. we reused my existing pistons and just re-ringed them. The block was reworked.

Great job for what i paid.

 

This one has 30K miles. 6.000$ including exhausts. However international shipping may cost...

My guess is this he meant the IMS bearing. Because the main and rod bearings are only available from Porsche AFAIK. I believe Flat 6 is developing aftermarket bearings, but they are not ready yet. I would be interested to know for sure if the main and rod bearings were aftermarket, since this would be the first I've heard of them.

 

Lol, I am coming from the BMW community and buying my first Porsche and DAMN does Porsche rape people

13-15k to replace an engine is astronomical.

I say go LS1 or LS2. Motor should be roughly the same $$$ and find a shop who builds cars and have them fab you up a set of mounts. Go from there.

I put an SR20DET in a BMW and it was pretty easy in all reality

 

Example www.renegadehybrids.com

Although in my opinion most P-car owners are purists and would not go down that route.

In any case, if you plan to keep the car forever then by all means Frankenstein the hell out of it.

Otherwise, there are certainly more resalable alternatives out there.

 

Have you talked to Jake Raby and his shop Flat 6 Innovations? The guy know more about Porsche engines and rebuilding/tuning than almost anyone in the industry.

Give him a ring and he will be honest with you and more than helpful, even if the route he suggests has nothing to do with his shop or making a sale. I know because I've had the pleasure of speaking with him about one of my problems.
