I need some help. My friend has a 1982 XE falcon. It has the 3 speed auto and Carby Alloy Head 250.
He doesn't really know much about cars and he thinks to get a bit of performance that he has to upgrade to a commodore V6!!! I'd like to keep him away from that if possible, show him that you can get some decent performance out of the 250.
So can you get some alright performance out of these motors, enough so to maybe cane my EB, and commo V6's??
I've heard talk of people getting 12's and things like that relatively cheap, well how about 14's - whats the path to get that?
Thanks guys - if we cant get this car going good he'll more than likely get a commodore being a Holden guy.
Thanks, but I think that might prove a little too expensive, it wouldn't take a turbo to impress him I don't think.
Just wondering what you guys with Carby 4.1's have done, what times you have ran etc.
Like for example you do the usual mods in an E-Series - cam, extractors, exhaust etc - and you get low 15's/high 14's. Can an XE pull the same times from these mods?
We would look at getting it converted to a manual of course...
Well just take a look at xdc351's XF wagon. He's done a bit of engine work, Cam, 465 Holley, extractors etc and is still running the auto and has done 15.43 down the quarter... Probably look at spending 2-3-4k on getting it doing low 15's depending on your mechanical knowledge and how much you can do yourself.
Well we'll definately put a manual in. I'm not to sure about what the go is with XE manuals though. Was it the 250 that got a 4-speed and 200 that got a 5-speed - is that right? Been looking around and not sure what gearbox to get??
What do people think about sure-cams (CLICK) particularly HYX80 and HY44?
Might get a spare crossflow head from the wreckers to attack with a die-grinder, then hand it over to a head-shop to get shaved a bit (how much off is good?), and then depending on what cam you guys reckon is best we might have to put a valve spring kit through it I guess....
So could a manual XE with shaved head, extractors, exhaust, slight head work and cam pull a high 14?
Can the cams be reground for these motors like you do in an E-Series, or will we have to use expensive billet cams.
You can get 10's out of the 250 if you have lots of ca$h. Ive got an XE and im going the turbo route. Been acruing parts for more than a year now, will be running when i finish this semester in a few months. Anyway, i have at the moment:rebuit 4.1, built for straight gas and turbo, with stage 2 cam in it, T04 turbo, HKS BOV, Garrett 42mm wastegate (running 5lbs at the start, but have a 12lbs spring too), Exhaust manifold, underbonnet pipes(including 'ford turbo' one, see avatar), 3inch stainless turbo back exhaust system, intercooler (big), all of this including installing the engine was $3500. I estimate i need to spend another $1500 on the gas system and tuning. So for $5k i should have the turbo on and running. Thats pretty decent i think considering most turbo kits go for a lot higher and dont touch the engine.
AND it will be fully engineered too.
Was it the 250 that got a 4-speed and 200 that got a 5-speed - is that right?
I believe that is correct. I think some XF 250s came out with the 5 speed box, but I don't know whether the box had been toughened up or not for this. I don't think a standard 5 speed box will hold up with a worked 250... I'd go for a 4 speed honestly & put up with the higher revs @ 100kph.
