How do you Build for Torque 3.2 Ltr
Hey Guy's,..I will be rebuilding a 2000 3.2 ltr engine, And Iam curious on how can you build for more Torque and HP,..Iam interested in more Torque first,with more HP as a bonus if thats possible,I already have the 987 airbox,74 mm TB,and plenum..I will be running headers also,..but I also want hi-way speeds aswell,..say a crusing speed of 80-90 MPH,..can you get the best of both world's ??
Thank's for the help.! Frank

You're on the right track. You're including all the proper components... already you knew that. Maybe a build thread?

You're on the right track.
Bolt-on's will only net you so much, but there is a gain to be had.
In order of ROI:
1. Exhaust; headers, cats, mufflers. (Get it to breathe out)
2. Intake; airbox, plenum, tb. (Get it to breathe in)
3. Tune. I got one from VR Tuned. they send you a kit to flash your own using your laptop. Truth on this: you won't see higher peak numbers, but you'll get much more acreage under the curve. Trust me; it's worth the $800 or so. But do it last. get all the other parts together and working first.

Well that's good to know..my other issue is Iam taking parts from a 3.2 that has a hole in the top of the case..I have a new case ( Thank's 78F350 Great case ) But I dont know what shape the crank ,rod's or heads are in..I do have a 2000' M.Y. bottom end from a 911 , I think I could use the crank and rod's from that engine if I need to correct ? Thank's again ! Frank

If the bottom end from the 911 is a 3.6, I believe that you would be happy with the torque :-)

You may add two more "add on:s".. It seem to be consensus that using the 996 intake does quite a lot, at least according to some who have tried it here on the forum. Also if you go for the 987 Airbox, you can also use the 987 MAF-tube. This WILL need a tune, or at least an updated MAF-table.

Thank's Gilles..That's true I will ck the cylinder size on my 911 bottom end,..And thats a good idea. Starter986 Ive read about that,Do you or anyone know know if they are a direct bolt on to 986 S heads ? that would be perfect Because I dont want to punch out my Boxster S cylinders ??
Thank's again, Frank

If the 996-intake is a direct fit? You need to drill some new holes in the head and lower the engine to make it fit.

It's pretty simple to drill and tap the holes to mount a 3.4L intake.
The port on the head is a pretty good match for the intake already.

Frank, the 3.6 crank will have a longer stroke than the 3.2

Hello...I have located a 996 intake system,..But the ports are more oval,my 2.7 is a bit more triangular, I have'nt pulled my 3.2 Ltr yet, so I don't know what those intake ports look like,..trying to figure my best option for building a stronger, reliable engine..? Thank's Frank

The lower portion of the 996 intake is a separate piece and mounts to the head with a metal gasket. The port is generally oval except for the injector mount. Is that what you're looking at?
Note, this picture shows the bottom of the intake facing upwards.
