Outer Limits 4x4 Board

Hi.
I have a custom made intake manifold for my gen 1 pajero. I made it cause of an EFI ocnversion, a few years ago. Now I'm looking to put the original stuff on. I read that a Magna TR head and intake manifold fit ok. Can you pls confirm this? Magna is an uknown model here so any info is greatly appreciated. I dont know if the same is true for Starion 2.6L models. In short, I'm looking for a way to fit a factory cylinder head and intake manifold to my 4G54. If you also can give me some links from sellers would be great.
Thanks

Do you have a efi conversion wanting to convert it back to carby. Or are you just looking at changing the std pajero head to a magna head?

When i did my efi magna conversion i swapped the head off a tn magna, and it fit perfectly and the exhaust stud pattern was exactly the same

The Magna has an East-West engine, the Pajero has North-South. The water pump for the Magna is located at what would be the rear of the Pajero. In short, I doubt that a Magna head will suit a 4G54 engine for a Pajero.

Um I beg to differ as the magna is a 4G54 aswel and I have installed a tn magna head onto my pajero. The only thing I had to do is remove the pully (on the left of the magna, back of the pajero) connected to the camshaft

Well, sort of.

If you used the Magna camshaft, you would've had to cut the shaft off the end.

I'm guessing you used the Pajero camshaft & rocker cover, and standard half moon, so you weren't left with a hole where the shaft drove the pulley.

Did the Pajero intake manifold bolt straight up?

Like I sai all I did is take the pully off and I am using the magna camsgaft and rocker cover. It does stick out at the back about half an inch and it does spin. The hole is sealed with a donut shaped seal which when I first instaled the head want on and oil went every were, but luckly the seal came wit the gasket kit I got for the head gasket.

Because I used the magna manifold for the efi conversion, it bolted straight up. But the pajero intake and exhaust stud pattern are exactly the same (in the tn magna anyway)

Thanks for the replies! I would like to keep the pajero camshaft (more low torque i guess). Is this possible with the magna head? Also you said for magna TN. In other sites i've seen a "TR" head instead. Is there any difference?

The Magna 2.6L 4 cylinder series went through from the first (TM model) to the TR as far as I know. After that, they had a 2.4L 4 cylinder for the 3rd gen Magnas, but this engine differs from the earlier models. The TP & TR models were fuel injected. The early (TM Magnas had problems with cracks appearing in the camshaft bearing posts. I believe that they sorted this after a while, so the later models should be OK. From what I know, the TP and later models were very reliable.

Fuel injection arrived in the TN; TP/TR had different manifolds with larger diameter & longer runners (from memory).

The heads evolved over time, got up to about 9 versions. Earlier versions had hemispherical combustion chambers, but later versions went to kidney shaped chambers (to help emissions, I believe). Later versions also had larger valves, but I'm not sure of the details.

I think the Magnas also came with roller rockers, which use a different profile camshaft. I believe the non-roller rocker set from the Pajero will bolt on.

Thanks Scott! I found at sigma-galant everything i needed. Does anyone knows any links of a wrecker where i can find what i need? (intake manifold with injectors). I have a contact in Sydney that can send it to me, but it would be better if i could point him to right direction...
Thanks again...
