Just starting my LS v8 conversion

[obthomas]

Now retired with the time to work on my 2003 Boxster S 3.2. Starting a LS swap. Got an adapter, flywheel and clutch on the shelf. Bought a junk yard L92 and have started prepping it for installation. Essentially turning it into an LS3. Ordered a LS3 intake, Saved the wiring harness and ECU for later. Deleting VVT and looking for the right cam. Need all the help I can get to get the balancer closer to the engine and find the right water manifold. It is going to be fun eventually cramming the LS into the Boxster. Others have done it so I am convinced I can.:dance:

The truck balancer sticks out the most.

The next shortest is the 4th gen camaro and firebirds. The 5 th gen cars went to the truck spacing.

Next in line is the corvette version with matching water pump.

The absolutely shortest set up they ran was on the LS4. You will have to get the front of the crank shortened. The water pump is moved off center to get it super close.

LS4 is the front pulley you want

Thats the V8 from the FWD cars. So its the shortest. You might be able to use a crank from an LS4 in just about any LS no machining required... but don't quote me there.


Gonna make your own engine cradle or buy a pre-fab one?


My buddy has a TB SS with a 6.0 in it. He went with a 216/218 cam... can't recall the lift, but it cranks out the power. Not much chop.

What heads are you gonna run? That should help you make your decision on what cam to get.

Update...Sprucing up my Junk yard LS 6.2 L92. Deleting VVT and going with a comp thumper cam 54-600-11 219/233 Decided to use the corvette accessory spacing on the front of the engine. Planning for Earls remote water pump manifold up front. will find or make brackets for alternator and AC compressor low on each side. Will make my own engine frame/cradle. There is an Aussie on Youtube just made one for an Audi V8 going into his boxster. Will pattern mine very much like it. Oh, staying with the L92 heads with rectangle intakes. This L92 is just over 400 HP stock. I hope to make about 50 more HP with the cam.

What's your plan for the transaxle? That's a lot of power to be putting through a 986, even the 6 speed. I'm super psyched to watch this go down though!

Others have told me that the transaxle will be fine with a billet side cover. Actually I think the axles will be the weak link.
