Car Forum / Ford / Ford Falcon / December 2004turbo engine for an ea ???
i would like to put a turbo in my '90 ea but was told by an old friend that although i could do it i would not be able to run very much boost pressure because of the compresion ratios and so would waste the turbo, he told me that you can get engines for the ea designed for use with turbo's but wasn't sure where or how much, i was wondering if some one in here could tell me wether it would be worth while getting a new engine or just tacking a turbo on to the the engine and how much it would cost and who and where in townsville or north queensland in general (!!GO MAROONES!!!) to see for a good deal > i would like to put a turbo in my '90 ea but was told by an old friend that > although i could do it i would not be able to run very much boost pressure [quoted text clipped - 5 lines] > townsville or north queensland in general (!!GO MAROONES!!!) to see for a > good deal I know that Modern Motor fitted a Sprintex Supercharger to an XF Falcon back in 1987 as a project car. As your EA's engine is similar to the XF I suggest you talk to these guys if you want to get more go from your EA: http://www.sprintex.com.au/ FF > I know that Modern Motor fitted a Sprintex Supercharger to an XF Falcon back > in 1987 as a project car.

Also, As far as turbocharging the ea, I wouldn't bother, go the engine swap. Maybe a later model falcon engine or somethin. The Ea was such a dog of an engine. Hope I have helped Cheers, Waity. > I don't claim to be the ultimate mechanic who knows all about all, That would be an understatement. Both the 4.1 and 3.9 respond well to turbocharging. They might not like a rev but both can make gobs of reliable torque with the suitable setup. > > I don't claim to be the ultimate mechanic who knows all about all, > > That would be an understatement. > > Both the 4.1 and 3.9 respond well to turbocharging.

As these old 6 cylinder engines did not like to rev hard, turbo charging would not work as well as a turbo improves as the revs increase. The sprintex supercharger would work down low in the rev range where these engines like to be operated at. The superchargers disadvantage is that it does not like to rev as the mechanical/frictional losses are high at high RPM. Which is not a problem in XF / EA engines as neither are worth reving beyond 3500 odd RPM. FF Or twin turbos. > > > I don't claim to be the ultimate mechanic who knows all about all, > > [quoted text clipped - 12 lines] > > FF > Or twin turbos. > [quoted text clipped - 17 lines] > > > > FF The plumbing for a twin turbo installation would be a lot more difficult. But if you could set it up that the turbos 'kick in' at different stages then you have a real potent engine. That is two different sized turbos. The smaller turbo to start proceedings and then the bigger turbo to take over at the top end. FF the multipoint ea is to bad, its the throttle body injection thats got the bad name, 4.0L is the better engine but the later the engine the higher compression, the best engine to use is the eb or xh ute that used the run out model eb engine the compression is 8.8. mate of mine is runnin stoch xh ute engine in his eb runnin 15 psi, made 255KW at the wheels (342HP) he ran it WSID drags ran 12.58 1/4 mile with slicks and a mod BTR auto, stock single wheeler 3.27 final drive, hardy no turbo lag(turbo is GT35R, 1.06 A/R exhaust, 0.70 compresser, ex 48mm wastegate) it all depends want you want it for street/ stripe/ drag car but one with turbo cars low boost for street higher boost for stripe, the turbo cause any where bewteen $7500 to 10.000 complete dependin on much you do yourself (u will need intercooler,pipin,hosein and clamps,turbo manifold,wastegate,oil lines off the sender unit and return line,wate line,dump pipe and exhaust,blow off vaule,fuel pump fuel regular,larger injecters,arfermarket combuter and of cause a turbo.
