yeah john coliades runs a straight 6 dedicated lpg turbo but it's in a mustang.

which engine is recommended? million dollar question. how mechanically apt are ya? do u have the facilities? do you want the grief associated with an engine conversion or do you want something u can get in and drive soon?

btw, similar engines in many ways but pretty much nothing is interchangable

[syko4d]

yeah good point

mechanilly minded

but not electronically minded the computer things is what will throw me off

wich engine do you run do you have a buildup thing for your car mate

Hey syko4d
Is the project a long term goal, or you have a shell waiting for a motor.
I think Te Jet has a turbo runs straight bullshit, :azza:
Get a plan first, right down a list of smaller tasks/jobs and break it down into time and cost.

i have the car but i want to do alot to it before i put the motor in

so a long term goal

but im just fooked if i can decide what motor to use

i don want a v8

turbo six is it although i just found what i think is a cheap supercharger

The 4L and 250 have similar potential so which ever one works out to be the easiest for you is the way to go.  The 4L is a bit different but some poeple like to be a bit old school and stick with good old pushrods.  If you are only after moderate power then either will work fine.

No much is interchangeable.  Pretty much the crank and conrods are the only things interchangeable.  Only the late 87DA 250 interchanges cranks with th 4L, there are plenty of threads about using the EF fully counterweighted crank in the 250 block.

bellhousings, flex plates, timing gear cylinder heads, block, inlet and exhaust manifolds are all different.  None of the manifolds even run the same bolt pattern.  They do have the same bore and port spacings though so you can adapt manifolds.

One area where the 4L is better is they can use the Multi layer steel head gasket which came out on the AU engine and handle a lot of boost.  The 250 needs the block or head o-ringed then an AQCL race series head gasket to handle decent boost.

thanx for your help every1 i really appreciate it

ok im sticking with the 250

it will come out and will be fully rebuilt

if you run straight gas will you need a carby?

i know that sounds stupid but if you dont need the injectors on a efi then yeah i feel stupid asking but why else would you put a eb manifold (inlet) on?

i want to be able to break traction very easilyas im driving not a stand still

also can you get straight cuts for the 250?

thanx alot guys you blokes are awesome

[BigNorm]

depends on what gas setup u use whether or not u still ant to run a carby. one alternative is using a efi throttle body setup ford or aftermarket otherwise a gas carb. if you're gonna boost it the throttle body is the way to go.

[pcman]

efi intake  with a impco 225 will let you have up to about 180kw

gas research setup around 350hp

theres talk on xfalcon at the moment about running dual impco 225's  but noone has tested it yet

[syko4d]

180rwkw would be plenty

what times would that get roughly down the quarter


would a modified eb plenum be ok?
