You will need all of the timing parts and thetiming cover as well as the intake manifold and throttle cable. The throttle cable will be hard to find and the imrcs will not work unless you buy a lot of wiring. You MUST have the engine out of the car to do a 4v swap. You will most likely need the exhaust manifolds too.

no i plan on porting them so the difference should be negligable in that sense, i would like to know more about making them work, i know they will bolt on... but i need them to function also, does this require a new harness or what? bc i thought i could use the gT computer (reflashed) and i dont see how a throttle cable would be a big deal ... hell no engines come with that

you may need a new intake ( i dotn know one this one)
as far as bolting it up. your best bet would be go to svtperformance.com and post under there most prolly have done it or have experience with this type of question

The throttle cable was discontinued a long time ago. To make the Imrcs work you will need alot of wiring.( I am working on doing this for my 4v swap.)So far I have engine harness and ecu as well as the ecu to engine harness and there is at least one more sectionI still need to make them work as well as the gauge cluster. It would be less costly to just delete the imrcsbut the secondary air injection uses the same wires and I live in CA so I need that to work.

98's came with b heads which i heard sucked compared to 01's and 03/04 are even better then 01's.
so unless you plan on porting them. look for 01's atleast (c heads)
