3.6 Engine Work

Raby, Brad Roberts, and a few other people here have been extremely helpful.

I finally found a shop that will do what I wanted. It's a small shop in Riverside that my brother takes his 996TT to. I was quoted for a 3.6L re-sleeved from a 3.2S. I thought I'd share it with you to get some feedback, and whether or not this is trustworthy and accurate.

I drive a '99 Boxster base

Engine case machine work will be done to a 3.2 to make it into a 3.6
Custom JE pistons to make it into 3.6
I'll have to get a new chip, various gaskets and bearings
I'll also need the third radiator setup, and a new front bumper that has the vent


He says I get to keep my non e-gas setup. He also says that it'll mount straight up to my current tranny with minimal fabrication work. I asked if I needed new gauge pod, and he told me that I could use my current one.

Is there anything obvious that I'm missing from this? Is this a reliable setup?

Done correctly the engine will be more reliable than the original engine.

987 airbox & filter
987MAF housing & hose
996 plenum "T" & 996 cable controlled throttle body
987 clutch
1999 996 DME reflash
Headers, midpipes & muffler
Injectors cleaned & flow tested
Engine balancing
LN triple bearing IMS upgrade
ARP rod bolts or LN rods

In addition to new gaskets & bearings, replace everything inside the engine that is worn.

To go from 3.2 to 3.6 you need to either bore it or stroke it. The question you should ask them is how they intend to re sleeve it.

I'll ask him tonight. He was kind of vague. Are there any other specifics I should ask him?

I would also ask him about the 'chip'. Probably a semantics thing but you don't chip these cars. You can however re flash the ecu /dme with updated programming. According to the lne website, a new flash isn't required so you may wish to hold off on that for now. I say this as I've heard that a 3.2 3.6 conversion can be quite peaky in power development due to restrictive intake and exhaust. So, to do it right you should put freer flowing intake and exhaust systems in (typically from a 987, etc as per the earlier post). The thing is depending on what intke system you decide to go for you will need a different flash. So, given that flashes can cost a lot, you should hold off until you know what you want.
