V2Cayman Posted 31May, 2015 Report Share Posted 31May, 2015 Hi, I've been looking everywhere for sizes (dimensions) of the Engines. Looking for the height of the 4.5L Cayenne engine for swap into Cayman. The LS series can fit with minor work, but these may be taller. Thanks.

V2Cayman Posted 1June, 2015 Author Report Share Posted 1June, 2015 Yes did a measure today, way too tall.. Was tempted to investigate due to the low prices of long engines.. Link to comment Share on other sites More sharing options...

V2Cayman Posted 4June, 2015 Author Report Share Posted 4June, 2015 I agree --- Its just a cringe factor of having a Chev motor in a Porsche and the modifcations to firewall required are, well, permanent. The V8 grumble from an LS just doesn't seem right on a Porsche either - crossplane crank to blame. Which brings me onto a little gem of an engine - seemingly. The AJPV8 .. Flat plane v8, 75 degree configuration SOHC. It's very light weight and the package will fit into a 22" cube and weighs around 121kg (about 80kg less than the LS1). More research underway.

Russ Posted 4June, 2015 Report Share Posted 4June, 2015 You're not really going to put a TVR engine into a Cayman are you? think of the reliablity (Maybe a K series Rover is more your thing?) Doesn't the engine need to be the same age or newer than the car for registration? LS motor, 2JZ (assuming it's a 2005) or VK45 or perhaps some variety of flat motor (unless you're keeping away from those for cost reasons) Link to comment Share on other sites More sharing options...

More research underway. even TVR guys are scared of those.it would be cheaper to source a gt3 motor, Link to comment Share on other sites More sharing options...
MFX Posted 4June, 2015 Report Share Posted 4June, 2015 This is an interesting concept. I dont imagine any V8 would fit under the standard engine cover, but if you bring it up into the cabin and fabricate a new engine cover it could possibly work. I am assuming you have a car with a dead engine. The simpler route would be sourcing something like a 996 turbo engine (if you are looking for more power) depending on your budget.

V2Cayman Posted 5June, 2015 Author Report Share Posted 5June, 2015 Thanks guys --- I'll do some more research. Link to comment Share on other sites More sharing options...
mikefocke Posted 19June, 2015 Report Share Posted 19June, 2015 More started engine transplants than completed ones. The physical placement seems to be the least of the problems. Think of the electronics and electrics. Link to comment Share on other sites More sharing options...
Euge Posted 23June, 2015 Report Share Posted 23June, 2015 If I had all the money in the world, I'd See if these guys would build one for the 987 platform http://www.synergypower.co.nz/ The build they did for the FT86 was incredible. Dry sumps and materials etc ... can read about it in speedhunters Link to comment Share on other sites More sharing options...
