V8 Swap in a SVX
I was just wondering if there has ever been someone who swapped a v8 into a svx. I have a green svx that is just for parts and I have a lincoln mark v8 that the suspension has damaged. Its a 4.6 4v V8. The ford Cobra motor. I think it would be cool to put it in my old svx. Its so sad to see it sitting there.

Re: V8 Swap in a SVX
I honestly don't think that's physically possible..

Re: V8 Swap in a SVX
Anything is possible.....but it'd be easier to stick an old school V-8 in it to avoid many of the wiring issues

Re: V8 Swap in a SVX
What wiring issues? Run the engine stand alone. Not much to merge.

Re: V8 Swap in a SVX
Yea, on an OBD 1 SVX this would be quite doable as long as you ditch the Automatic and manage to mate whatever V8 to whatever trans (STi 6-speed!) you use. Mounting it might be tricky, you'd have to mount it real low, a V8 can be a lot taller than an EG-33. LS1s have been swapped into pretty much everything you can imagine, so that would probably be the easiest thing to use.

Re: V8 Swap in a SVX
Skip that 4.6, as its HUUUUGE. Its the size of a old Ford 460 big block.
I'm quite certain that a GM LS family engine will fit, only concern is hood hieght and the engine subframe. Not the hardest thing in the world to make a tubular subframe, but either time consuming or expensive depending on your skills. Might not be needed, or just a modified stock one is all it will take. Just want it out there that its one of the few places you will see issues. People swap them into 240sx all the time, and people have swapped them into 300zx too. GM and painless wiring both sell "hot rod" wiring harnesses for the engine that will allow you to run the enging without making a custom wiring harness yourself. A stranger idea, but the Jag 4.0L V8's are suprisingly cheap. You want a 2000+ one if you go this route. It it definitely will be more work as no one sells off the shelf harnesses, but its a sweet little motor. The 4.0 with supercharger is a truely epic motor in its own way, but might have more issues getting it in. Mind its likely better and cheaper to just buy a 2000-2003 XJR right now and its much the same size as a SVX. Lincon LS/Ford Thunderbird uses a "3.9L" version but I have no idea what if any changes they made for those models. Last edited by XT6Wagon; 06-04-2011 at 10:21 PM. |

Re: V8 Swap in a SVX
Old School V-8 and transmission, you'll never bolt a V-8 to a Subaru Transmission, due to Starter issues...
And on a carbed V-8, the only wire to hook up is a hot wire to the distributor....

Re: V8 Swap in a SVX
Sound cool to have V8.
Just the sound of a V8 it is worth it..

I don't think a LS1 would fit where you would want it at least, same goes for the modular ford 4.6 and 5.4. They are both quite wide as they go up compared to the 302. Jag 4.0 is way too wide and lacks a viable manual tranny option. All of these engines you'll want pretty far back (which takes out the awd tranny set up in the Subaru sense at least. I have a 302 that could be yours complete with t-5 and the engine harness and computer as I've decided to go with a ford 3.7 in the TVR.

And Sure the Jag has manual transmission options. Guess what the V8 in the 2005+ Aston Martin V8 Vantage is? Might even be a GM bellhousing pattern as they used GM 4spd Autos in the XJ all the way till 2004. I don't have the actual dimentions, but its a very compact little V8 as it fits in the old XJ which has no great amount of room under the hood. Course if you are really really crazy, The Jag V12 might even fit. Someone managed to shove one into a miata.... Sure its stone age lump of crap, but just imagine a V12 SVX. Still 350hp before mods. |

As for the LS1, take a look at the unibody of the SVX and tell me how you plan to put it in there without cutting out 3 inches on either side of the unibody?. The Jag v12 will result in 4 inches gone per side (so then you are talking about cutting inner fender out too). Yes you can simply move it forward but then you're in need of plenty of other work to the suspension, rad support and figuring out a place for the radiator for either of these options. As for the Jag V12 being a stone age lump of crap, you really show your ignorance on that one.

Re: V8 Swap in a SVX
when i had an sts i always dreamed of dropping the northstar v8 from it into the svx. it with the transmission (fwd) would barely fit if you didn't have a hood. the engine itself is actually pretty small for an 8

Re: V8 Swap in a SVX
Set in, and back against the firewall, a small(ish) V8 like a chevy, or ford smallblock, Northstar, or just about any import V8 SHOULD fit. that said, getting it low enough to clear the hood, and keep some sembalance of handling, may be troublesome.
