XR6T into Mustang??

FalconXV · 13-05-2006, 08:29 PM

Hey. Have a friend in the US; thinking of getting him to bring over a Mustang fastback (circa '65). Was wondering what would be involved in getting a BA/BF xr6 turbo engine into one; if anything similar has been done. thanks/.

I don;t exactly know what would be involved, but I would imagine that it would be alot.

BPXR6T · 13-05-2006, 08:52 PM

I'd be more thinking what could be done to get a boss motor in one... ;)

dynosteve · 13-05-2006, 09:30 PM

i think you'll find the motor will be too long to fit

My thoughts exactly, so go the BOSS 290.

outback_ute · 14-05-2006, 07:56 AM

The good news is the 4.0 engine is based on the original 144ci Falcon six that was also used (as a 200ci?) in the Mustang. However as dynosteve says it is longer - the 250ci version was longer and the 4.0 evolved from that (it is actually 243ci), and I expect it would be longer again due to the ohc cam chain. Adding to the challenge is you want to have an intercooler in there somewhere. I'm sure it is possible somehow!

The easiest way to go is get an engine complete with loom and ecu, the ecu is the same basic unit as used in the states and can be fully reprogrammed.

Now aren't the early Mustangs based off of the American Falcon platform? I remember discussing putting a 4L into an XP coupe at one stage with my old boss from Coles but I was told it was too long to put into the engine bay. Whilst then we would assume the Boss engine is a good fit instead, your mate in the US should just buy a 4.6L Mustang crate motor from the new jobbies.

nb_351 · 14-05-2006, 07:29 PM

i dont think it would be that hard to fit it in there... yeah theyre not the biggest engine bays, buti think youd struggle widthways to fit a boss in there... youd have to chop the strut towers... just about anything can be achieved though... look at rod hadfields chev...

XR Martin · 14-05-2006, 08:32 PM

How would it be too long? The base Mustangs ran a 200ci I6, which is pretty much the exact same engine as our 6 cyl.

Except that it is pushrod, not DOHC, nor is it Dual VCT... alot has changed since 1960.

Better off building up a good Windsor (as per what the Mustang originally ran) - an EFI one if you want new-car reliability.

XR Martin · 14-05-2006, 09:32 PM

Its still isnt going to be much longer, only higher.

Plenty of room!

Steffo · 14-05-2006, 10:10 PM

As opposed to...

You seriously think there's not much size difference?

I'd love to see it done, but it would be a very, very costly exercise.

Grechie · 14-05-2006, 10:26 PM

same id love to see it done, defently something different there n very unexpecting, catch anyone off guard

LUXO_8 · 14-05-2006, 10:28 PM

of course the BA motor is quite a bit longer.....the old motors were just a bit longer than the inlet manifold on the BA engine

LTDHO · 14-05-2006, 10:50 PM

It would be just as easy fitting a 290 GT motor!

Easier to fit a 200 5.7W EFI in it.
Swap winnie for winnie!

ON_DUBS · 15-05-2006, 11:39 AM

nothing a good cut n shut wont take care of.

seriously going to need some physical measurements or you'll never get an answer

XR Martin · 15-05-2006, 12:23 PM

Imagine where the human race would be if we listened to people who said it couldnt be done. We'd be still in caves freezing our asses off eating raw meat

Ryan · 15-05-2006, 12:31 PM

This sounds alot like the guy at CalaisTurbo.com, that wants to put a XR6T engine into his VL.

Bossxr8 · 15-05-2006, 06:21 PM

Length and height would be big issues. The BA is a fair bit higher than even the AU motor was.

XR Martin · 16-05-2006, 02:08 PM

Ive done some measurements. Length of a pre-crossflow 6 is 77cm from block to balancer, a '92 4L is 80cm from back of the block to balancer.

Going by those earlier pics of the Mustang bay, an inch isnt going to be hard to find

Now height is an issue, but remember the bonnet on the mustang is fairly level all the way to the front, unlike modern Falcons which slope down.

16-05-2006, 02:13 PM

A buldge could easily fix that problem.

Remember you could probably bring the radiator and thermofans to the other side of the rad support panel if you needed more space.

If you have the budget of say 10-15k Id say go for it.

rag top · 16-05-2006, 02:53 PM

I reackon it would be pretty cool - Do it.

A lot of people said a clevo would never fit in an RS2000, and that has been done!

I feel sick...

As far as an XR6T Engine into a stang goes i would love to see it done and for those saying just throw in a 260/290 have a look in the Sponcers section under the blue oval garage and have a look how hard it is, not real easy...

Trouble is you might want to put the intercooler in front of the radiator too.

If I'm not mistaken, VCT engines are slightly longer then the non VCT's.

**ebxr8240** · 17-05-2006, 11:57 AM

Set motor back into firewall approx 30mm and you'll be fine...
The new motors don't have aircleaners on top of them which gives them room....

At the head perhaps, but its still not going to be any longer at the crank pully

Ringo · 17-05-2006, 01:58 PM

I think its sounds interesting.

I also think it is possible albeit it will take some sorting by someone who knows their stuff.

Me? I'd throw a EFI windsor in there like everyone else....

070mstg · 17-05-2006, 11:06 PM

if you're serious about it have you considered a later model? a 67-68 will give you a bit more(few inches ). a 69-70 will give you even more. (also i personally think theres enough 65-66 mustangs around.)
my '70 engine bay is big, very similar in size to say an XA-XC falcon,probably narrower but longer. (clevo is a fairly tight fit if towers untouched)more room in front of radiator than a falcon of similar era, theres,theres a ton of room in front of radiator (for intercooler,air cond,thermos) etc.
then if you dont mind te 71-73 models i think you'd have tons of room. they're looong
you could easily get more length out of a stang with a custom radiator and some reworking of its positioning.i think i could get the radiator forward probably 2 or 3 inches without too much hassle (with a custom radiator)
