The v8 is certainly not as wide as the dohc flat 6, but your right about height wise. The thing is though, the 914's 4banger was just a tad bit shorter then a v8 with a carb. Luckily the LS1 isnt as tall due to the efi and maf placement which would be flipped around. I need to locate some measurements for porsche 6, but I'm betting the LS1 can be fitted in there as I've found some LS1s that have been shoehorned to even tighter spaces ala 993s. As for the DME, isnt this just going to be replaced by the LS1 pcm anyway? Oh someone has already came up with the solution for mating an SBC (LT1 this time) to a boxster 5spd and resides in a 914 as we speak. Again my comfort tolerances are alot more different then others so aslong as that motor runs, the suspension works, and the drivers side window is down, I'm all for it

With a just a quickie google search, it looks like I can find non OBC cars and the DME looks like all it does is control the motor what nots. I think I can take the same approach as the FD Rx7 guys on how they deal with the ecm issue.

This would be awesome, seems like I have seen a v8 swap done to everything except the boxster. But Id really be suprised if this could be done without major modifications to the chassis. length wise you are very limited... pop the service cover on one and take some measurements... the flat 6 is literally crammed into the car.

Lets hope not, but there probably will have to be some massaging done to get her in there. With the 914s for space, some folks have resorted to banging the firewall a bit to just clear the belt assembly as well as moving the tranny back a few inches. I guess its time to start visiting dealerships with a ruler and tape.

The LS1 is very light and with the FI, fairly low. I think you could get that bad boy n there.

350HP and 375 Ft lbs of torque-2002 spec.

Wheeeeeeeeeeeeeeeeeeeeeeeeeeeee!

The LS1 fits in the 944 and the 911.

Can someone please tell me why you would put an American engine a PORSCHE? The 914 with the Volkswagen engine was one thing,it was not 100% true Porsche. Putting a v8 in a Boxster isn't what Porsche is about. Porsche has used smaller engines and created amazing out put out of them,they are the whores of engines. Why would you want to mess with that? Keep it in the family,put a 3.4 in there. If you put in the American engine you would also as well lose the Porsche whine,there is no substitute.

Sorry, but IMHO, the ls1 and the ls2 is simply a much better engine that any normally aspirated Porsche now being produced. Cheaper, more power, more topque, more durable, on and on.

Bring the conversion kit on, I am ready!

Thats exactly what I'm talkin about . Mid engine, rwd, under 3000lbs with that kinda power = goodbye 997. I wonder what it would be like with a proper heads and cam combo at around 450rwhp

Oh yeah I know about renegade. Its just the 986 platform has everything better to offer. Well maybe not engine bay space but cant win them all.

Lets see here...

-Ronzi
The car will see track time but it is never going to compete in anything due to the fact that it would be stuck in unlimited class (ala all out race cars) in any sanctioning body which this car certainly is not. Besides I dont think people buy or modify cars to make others happy, especially PCA or this collared shirt crowd you speak off.

-Dr. Kill
I wonder what people will be intrigued in more, the lopey v8 thats coming out of a stock looking boxster or the mullet sporting asian driver

-RandallNeighbour
I bet porsche never envisioned that 20 years after the 914, enthusiast would be putting all sorts of p-motors, v6s, v8s etc into a chassis and aswell as the transmission that were originally designated for less then 100hp all the while being VERY competetive in any of the sanctioning bodys This just goes show how overly engineered the cars are in the fact that even with the extra power the chassis took it like a champ. The funny thing was that the 914 was made over 30 years ago, so you can imagine just what the boxster chassis can do given the right circumstances.

-rdancd816
I hope I dont come off as some muscle car nut which I'm certainly not. Muscle cars have their place, just not in my garage and this porsche is not going to be in that sterotype either. What I want is an all around performer and not some drag car.

-Finallygottaporsche
The bang for the buck for both the c5 or any of the 911s is just not happening for me when compared to the ls1/boxster combo. The FD rx7 guys have been doing this and the same principal can be applied here. I dont see whats the point of spending more for a lesser car, especially here in socal where 911s and c5s are almost just as numerous as hondas/toyotas. What other mid engine rwd car, that will probably weigh lighter then the CGT, do you see thats as good as this platform for this price? As for working on them, its not like the things are easy to work on as they are now so I'll bite the bullet.


-olly986
On paper alone it looks like it wont drastically change the handling which is what I'm going for. Google the LS1 and you'll see what I mean. As for the emissions thing, the law here in cali states that you can use any motor aslong as its from a newer car along with its stock emissions devices. Someones already mated an LT1 to a boxster 5spd and the LS1 is basically about the same bolt pattern. I think he quoted somewhere under a grand to get it done (thats along with the clutch/pressure plate, etc )

I don't live to far from Pomona (yeah, I know, I'm not that excited about that fact either) - anyway, I passed by that area on the I-10 and believe it or not, saw an asian with a super tight mohawk/mullet driving a hot 78 Camaro with the back end jacked up atleast 4 feet. Ironic thing, it had a center exhaust and a Japatucky personalized license plate, wshiwasabox -

I think this whole thread is a scam by a schlitz drinking, luke duke loving Hemi hopper who's just trying to get a rise out of a bunch of guys who appreciate true automotive engineering and drive real cars!
