MK3 2.5 swap

**88vwFox** · 04-30-2009 02:51 PM

the side by side pics of the heads tell a great story. plus the fact the new 2.5 uses the same bell housing as the old I4's. how long is it from crank pully to bellhousing?

this is a great swap. it's like the new audi tt rs. 2.5l 5 banger turbo AWD. great combo, fyi the new audi is rated at 325hp but it's FSI. I hope you crush that.

ridiculous

cant wait to see a finished product. I thought my mk2 vr6 swap was cool.

**vr6tjet2** · 05-01-2009 11:04 PM

yep its a nice motor .. as for the lenght of the engine block a conpared with the VR and if i remember corectly the 2.5 was like 1/2 inch longer than the VR but im not sure ...it was longer but nut by THAT much ...will remesure it soon ...we started to rebuild the motor will post some pics soon

and for the TT-RS you want me to crush ..i would'nt worry about that

**88vwFox** · 05-03-2009 11:13 AM

not to TJ but i would like to know because the vw fox only came with the classic 1.8l 8v and the old I5's use a different bellhousing, so if the new I5's use the old 4 banger bellhousings then it would be a MUCH easier swap. The hang up on the fox though is the room you have to work with in LIMITED to say the least. Just wondering if it would fit.

Back on topic, I ALMOST sold everything i had a couple years ago to get a mk5 rabbit just to get a 2.5L and see if anything could come of it. good to see it's being pushed.

it bolts to the fox tranny thats for sure .. but i cant tell you if it would actualy fit under the hood .. that would be a sick sounding fox tho

**Golf 2.0T** · 06-07-2009 06:15 PM

the work on the car started

only got one pics ...more to come

motor in the engine bay but not in actual final position ...

had to cut a fews inches off the passenger side rail for the motor to fit and the oil filter comes in contact with the front crossmember

more info soon

**thewhitsnpt** · 06-07-2009 09:04 PM

progress is good

**Mr. Ninja** · 06-08-2009 01:38 AM

Thats a cool swap. I'll have to pay attention to this one. Alot of hurtles that you have yet to overcome, but thats the fun part.

**vdubwardo** · 06-09-2009 04:18 PM

amazzzing build!!

**Golf 2.0T** · 07-01-2009 07:50 PM

here is the progress so far .. the last pic shows what had to be removed from the passenger side rail ..

it took 3 100% custom made engine mounts and some minor triming of the 02M and engine block for them to fit together

damn that is one hell of a post. If people keep up these kinds of swaps soon it will be as bad as.... dare i say it. Honda's. LOL. VW needs a place that can make mounts for any vw motor to fit into everything.

Great work looks like it's going to be very nice.

**notso2slo** · 07-03-2009 10:29 AM

haha, I seriously doubt VW ever intended the 5 cylinder to fit into a mk3... there's a reason they didn't put one in to begin with!

**Lloyd Plumtree** · 07-03-2009 10:56 AM

Looking good. I`ll try to post some pics of mine frame rail before I reinstalled the motor. pretty big piece that needs to be cut out.

yes you gotta cut for the engine to fit ..the motor is kind of boxed into the frame .. we were kind of surprised when we had to cut that much since the motor was not significantly larger than the vr ..but what we forgot was that the VR is like inclined 15* forward ..and the 2.5 is like any 4cyl so 15* backwards ..and the space between the side rails gets narrower near the shock tower ...so if it would have been forward like a VR it would have fit right in , probably without even cutting the rail ... and all the engine mounts needs to be fabbed up since were using a 02M ... and the cross member needs some modification because of the oil filter housing that comes in contact with the stock cross member...next thing we will install the rear diff and drive shaft ..oh and we started the tubular 5 to 1 exhaust manifold

thank you all for the comments
