x51 996 3.4 kit?

Hey guys, So I've recently purchased a gemballa kitted 996 with a fair few mods and have been trying to get to the bottom of all the work done so far in addition to the gemballa kit/wheels/exhaust/x51 etc I'll be keeping it long-term and want to go nuts with it over time but would love to know what it's starting off at. It started life as a 3.4 with X51 kit so the question I have is: I'd read that the x51 included a different crank with a longer stroke (but in other things I've read this wasn't mentioned). Did it, and if so what does that result in engine size wise? Am loving it so far, it feels a lot more frantic than stock 3.4 and 3.6's I'd driven prior, albeit some were tiptronics, but feels very snarly with the higher rev limit and little extra torque. I've barely been able to find any tangible information on the x51 though.. My OCD is intrigued to know :lol: Cheers

as far as Im concerned, you need to find out from gemballa what the engine has. If they did modification to it, then they would have the record of what they did and what improvement it did to it. they could have changed internals, who knows what. Id get their records and find out what parts they provided, what ecu software they installed, what hp is it now.

Congrats on the purchase. How about some pictures? The X51 3.4 kit did not include a crankshaft. It indules the following parts: 1 - 000 044 100 10 Piston Set 1 - 000 044 100 11 Gasket Set 1 - 996 104 982 01 Cylinder Head 1 - 996 104 983 01 Cylinder Head 1 - 996 110 980 00 Intake Manifold 1 - 996 110 983 00 Intake Manifold 1 - 996 105 991 00 Camshaft 1 - 996 105 992 00 Camshaft 1 - 996 105 996 00 Camshaft 1 - 996 105 997 00 Camshaft 1 - 996 106 037 51 Oil Cooler 1 - 996 107 988 00 Oil Pan 1 - 996 111 991 01 Exhaust Manifold 1 - 996 111 992 01 Exhaust Manifold 1 - 996 575 141 02 Duct 1 - 996 106 665 55 Hose 1 - 996 106 641 59 Hose 1 - 996 106 666 52 Hose 1 - 996 107 980 00 Oil Pump 24 - 996 105 994 00 Cam Follower 2 - 996 110 985 01 Elbow 1 - 996 107 984 02 Hose 1 - 996 573 980 00 Hose 2 - 996 107 221 51 O-Ring 1 - 996 104 995 00 Heat Shield 2 - 900 075 495 00 Bolt Kit 1 - 996 504 485 02 Bracket 1 - 996 504 487 02 Bracket 1- 996 505 553 05 01C Lower Valance I own this kit and plan to install it on my track 996 later this year.

That's awesome, thanks! They must have been mixed up with the new camshafts perhaps.. Thanks for the link too, it's a good read From a bit more reading, Seems like the emphasis of the x51 is mostly on lubrication and cooling (I believe from the factory it also has an additional third radiator which the Wide body cars eg the 40th don't have due to having the larger radiators out of the box?) rather than out and out power, but with the higher rpm etc, it feels a lot more alive than others I had driven, fell in love! sure, here she is at the minute Will take some better ones when I'm home. Got a load of things I want to do with it, first being a thicker alcantara wheel to match the headliner

Nice ride! Glad to hear you can feel the difference the kit makes. It looks like a perfect kit for my car. I need that extra push in the straights and the added reliability these part provide is a plus with a track car.

thanks! Actually didn't intend on tracking the 911 as I'm building a track car, but I can't wait to get it down there. Yeah it's hard to tell not driving them back to back, but having driven a few there's definatley a little more urgency, the extra torque and higher rev limit seems to make it a bit more usable and the delivery feels different to non x51 3.4s or 3.6's I've been in, it feels like it comes alive a lot more around the 5k rpm. (Also looked at a 997s but have always been a sucker for the controversial 996 looks!) Some of this may be a bit of a placebo due to the suspension and exhaust mods too that said. A contact may thinks he may be able to chase something up based on the vin/engine number so it'l be interesting to see what it comes back with. Want to get it on the dyno next month just to see. Long term want to get a balance between power/reliabilitiy but staying lightweight and NA.

Congrats. With the secondary oil pump on there, you owe it to yourself to take her on the track at least once. The urgency you feel is the revised throttle mapping.

This kit is for NA 996? I'll keep my eye out for one if so. Congrats on the purchase!

Cheers Yep it's for the NA, by all accounts an expensive retrofit but seems well worthwhile even if just for the extra reliability and drivability hehe Twisted my arm, booked up for the next track day and have a few bits and pieces to help get ready for the occasion I suppose that makes sense, been away from it for 3 weeks so can't wait to have a play tonight!
