4.6 Callaway engine in 4.6 HSE

I just picked up a 98 HSE with a bad motor on Thursday. I just picked up a 4.6 from a '99 Callaway today. I know the top end is different, but what do I need to run it? I snagged the engine ECU and MAF, but the air intake tube and airbox were broken in half and missing. I also grabbed the transmission and transfer case. Other than a broken battery cover, and a single lug nut pressed into the mud, thats all that was left. I know the TCU is specific to this transmission, but unless it is located on the tranny itself, I do not have it.

I guess my question is, can I use the stock air intake tube and air box from the 98 4.6? Is it worth taking out the working (apparently) transmission and t-case for the Callaway stuff?

Thanks in advance.

Email http://www.v8developments.co.uk/ and see what they suggest. You have some choices. Piper do a modified RV8 fast road unit. JE Engineering do one as well which IIRC is called the JE-101...

The Callaway project is very interesting. One of the LR magazines did a write up about it about 6 months ago. I think Land Rover were getting 20 horses less than they were advertising and asked Callaway to try and put the problem right. :doh:

I do not have the front axle or the TCU. Honestly, I dont think I need to upgrade my diff. Its an extra 50lb of torque or something. I drive easy in my Rover, so I dont see it being an issue with the factor 2pin front diff and axles. I am going to use the Callaway Torque Converter and probably the transfer case for its gearing. While I have it all out, I may even put the Callaway transmission in, just because it has lower miles
The standard drivetrain should be comfortable with this extra power. It's not that much over the standard to make any difference. The standard powertain was designed to take 300bhp or so.
