Outer Limits 4x4 Board

Asking on behalf of a mate at work, who had his 94 1HD-T 80 series drop a big end bearing, and is now looking at fitting a reco long block and getting the pump and turbo redone too.

Will the 1HD-FT fit into the same hole as a 1HD-T left? I know the blocks are the same, but is there any differences to the heads that will affect things? Like needing new injectors, manifold etc.

And is there any advantage to fitting the 24 valve head engine? prices for reco engines seem very similar between the two.

Cheers in advance guys!

yes, the injectin pump and injectors are different, ie they run different pressures etc. as far as physical fit, I think they are interchangeable but not 100% certain.

Im not sure about the manifolds, 1hd-t is 2valve, HD-FT is 4valve, so I would be suprised if the manifolds were the same

the HD-FT puts out more grunt

check out 80SCOOLfor a conclusive answer

tappet cover, pump, injectors, some accesories (different brackets)
exhaust manifold is same size but different port shapes.

pretty easy swap tho

you cant swap anything....you could buy a complete hdfte and put the pump and timing gears in it from the hdt using hdft injecters...but for the dicking around, you might aswell put the hdfte from a 79 in it and wire it up....more power again....see if uu can get a complete hdft...you wont

And you've got bucklies finding a HDFT in bits, I've been searching for ages.

Cheers guys, I'll let him know. He's on a pretty tight budget, but is going the Reco motor route just for completeness.

If the budget is tight get a 1hz and bolt the 1hdt turbo on. It's a compromise, but could be done for just the cost of the motor (about 2k on average)

probably best just to rebuild the 1HDT
