[thedjse]

As title is there many changes that need to made is worth the hassle etc?????

Have you blown the engine in it just now? If so, not really, although the manifold is different afaik

Yeah my current engine SMOKES!!!! like mad and the compression is down im in a limbo of whether to reubuild it or throw another one in

 

[levaz]

rip old out, fit new.

job done.

Thats what i plan on doing thats why i asked if theres much difference in the engines

 

[levaz]

If i remember right.
Ph1 had larger exhaust ports on the head.
182 had a better matched lower inlet.

Thats about it aside the obvious (fbw throttle body/exhaust manifold)

 

[thedjse]

what about looms???? Throttle pedal?

 

[levaz]

Just use your throttle body with cable throttle

 

[Djw John]

The breathers are different so
I believe you use the 182 inlets but with the ph1 throttle body. I'd like a second opinion on that though @Budgie

 

[GrahamS]

The only differences between the engines are the breather on the cam cover which you can simply swap over. As said exhaust ports are a bit bigger on the ph1 but the exhaust manifold bolt pattern is the same. Your'll use your existing inlet plenum so there will be no difference with the throttle body. The ph1 throttle body you don't need.

So its fine to fit the 421 manifold to a ph1 yeah?

Yep, once you've swapped over the breathers, you can use your existing inlets.

If your new engine comes with inlets, no problems using those. Just need to make sure the vacuum pipe fits on.

 

[Mr R.]

Mike im sure you can't use the 182 inlet as a PH1 has a ICV.

 

[GrahamS]

sorry I read this the wrong way round. Swap the ph1 breather onto the 182 engine then use all the ph1 inlet, tb etc on the 182 engine.

Yes you can do, i have the 182 exhaust manifold on mine but i also have a de-cat and a Ktec single box system.

 

[Finny]

what does it go like mate alright yeah? ill be putting a decat on and already have a stainless stealth on...will i need to just buy a 182 decat and thatll be that?
