Ok, got it in the right forum this time.....



This idea was given to me by another member here, who exactly it was escapes my feeble mind at the moment. Anyway, there were quite a few changes to the engines and trucks from their introduction in 1989 till the end of the 2nd Gen run in 2002. A lot of things were upgraded, some are a direct fit into our older trucks, some require mild to extensive modification to make it fit. Seeing as we, as a group, are fairly fearless and adventuresome in our quest to make this or that better for our old rigs, or due to the scarcisty of aftermarket stuff for our trucks, I thought I'd start a list of stuff that will fit, based on my own experience and readings here.



Turbo- direct bolt on to the engine. If the exhaust housing of the "new" turbo is wastegated, the downpipe will have to be either shortened or moved back about an inch and a hair. If you lack the heatshield of the intercooled trucks, I would highly suggest cutting the DP after the turbo clamp flange and again right where it fares to 3", and reweld the flange to the DP,taking a total of an inch and a half or so off the top end of the DP. ALso, if you are putting a HX35 or HY35 turbo on a nonIC truck, you will need to get or make a bigger intake hose from the filter, and rig up a way to plumb it into the intake. Take a look in my reader's rigs for pics of the HX35 install.



Head- from my reading, direct bolt on. Some have said flow is improved slightly over the older stock heads. I have no hard evidence (from a flow meter) to refute or back this claim. Some accessories (t-stat housing, intake, heater hose routing) require some creative thinking.



Exhaust manifold- direct bolt on from 12v; 24v manifold will not work. The ports are different.



Clutch- The stock clutch and flywheel from your Getrag will work with a NV4500, provided the NV4500 has the stock 1-1/4" input shaft. You should research into whether you can use the flywheel adaptor and starter. Bellhousing is different I know.



Intercooler- Will fit with some modifications to the radiator core support, and new piping/ boots, as the 2nd Gen cooler is a bit wider than the stock 91-93 IC, it can work. Some have put the newer style ones in upside down and had a good fit. I personally plan to do this eventually. (have been planning it for over a year, so dont hold your breath waiting on me)



Front 40-20-40 split bench seats- requires an adaptor to be made to bolt it to the floor. I'll look up the thread and post a link here for specifics.



Radio- For AM/FM CD or CD/ cassette, I have been told it is a direct bolt in, plug and go fit. Dont know for sure; will find out as soon as I get the cash. I miss being able to play Chris LeDoux and Toby Keith when I want to.



Someone else chime in here with what is required for axle (D80), auto transmission, and any other swaps you can think of.

For those with an auto, The second gen flexplate is a direct bolt in and supposed to be stronger too. I haven't had to do it to mine, but a lot of the others here have done it.

It will interchange up to at least a 97 model with no problems. The thing to remember is our older model radios have the green light to match the dash lights. The newer one might have red backlighting in it.



The one we installed in Case500D's truck last summer had the red backlighting. It is kind of annoying at night. I like the green backlighting to match the stock dash color.
 
On the newer seats, if you DON'T want to use the newer center seat/console, the seats will bolt right onto the baseplate of the stock buckets. Check out my Readers Rig for pics.



I got what was claimed to be a 01 radio/cassette, off EBay, and it was a direct swap with green lighted numbers.



Concerning the many changes, why did they stop using the D and W designation, and why the extra zero on the number.

I have heard that 2nd gen drivers are not compatable with 1st gen trucks...

But that may only be a rumor... :-laf

Hardy, harr, harr... :rolleyes:



Here's a good one for you, the P7100 will bolt right in with some creative thinking...



Same thing with a p7100 in an ISB engine... ;)



A p-pump engine will bolt right in with some creativity. So will an ISB, but who would EVER think of doing that!?!?! :rolleyes:



I will still hold firm, the biggest weakness of the first gen truck is the injection pump (well, and the transmission, cowl area, and front suspension... :D ). Otherwise, it's a much more rugged truck than any other models.
