I could have got it in without an problems. I did cut out the very center of the upper radiator support, welded 1/8 plate metal to it, matched it and drilled holes to match the existing radiator mount holes, so now the whole center section is now removable, to make working on the front of the engine very easy. I am getting the driveshaft shortened Tuesday, so it should be driveable by next thursday or friday. Not too bad to have swap like this in and completed in a week or less. Motor sounds very good and strong, I need to order a turbo gasket and a MAF. But first I am going to try wiring a Ford Ranger MAF the size matches and the specs. So in theory if wired correctly it should work and priced way less. I have some much better pics with my camera I will post up later, all those pics were from my phone.

It doesn't look like any firewall mods, and did you just flip the shifter plate around or did you do a front transmission case swap? I think its cool that its like the VG's and that it just bolts into the front crossmember. peace.

Yes I just flippped the shifter plate 180 degrees. As far as bolting into the crossmember, it does not. I had to cut the engine mounts of the frames and move them forward 6-7"s then reconfigure and reweld them to the frames. Match the tail section for the tranny mount, make sure the engine is centered and high enough to clear the front sump oil pan so it does not hit the steering centerlink and the turbo clears the steering shaft. The Z24 engine is a rear sump, so it makes it a little tricky. The trans mount went straight in with no problems. Not sure about how long it will be now before I can get the driveshaft cut down, because I live in Baton Rouge and we are about to be nailed by hurricane Gustav. But when it gets done I will post up some more pics.

WOW! It looks like factory mounts from the pics so, good job on the fab skills! I didn't realize the RB20 was a front sump design. Anyway, yeah keep things bolted down man and come back to us when that **** b lows over. peace.

Does someone know if it's harder to fit an RB20 in a D21 4WD?

should be the same exact swap as mine other than trans issues and possibly the front sump oil pan possibly interfering with the front axle.but anything is possible, it time time, thought & money

there are a couple mods, the defrost duct and the two side ducts are different, the steering column mount it different and needs modding, the center support and driver side brace is different, and the lower mount on the left and right sides are different. the ac panel from the old d21 fits back into the 97 dash, all you do is swap the face plates. the instrument panel has to be completely rewired, and you will need a 97 speed sensor because it is electronic not cable.
SO basically if you have a 97 truck that has the complete dash and can get the speed sensor, your good to go. It sounds like a lot but it's really not bad.
If you decide to do it, email or pm me and I will email you both IP panel wire diagrams to rewire it. ANYHOW..... I cut and shortened the driveshaft, it's in and the truck drove out the shop and back in on it's own power for the first time. I just ordered the AFM yesterday. I put the carpet and 79 280zx center console, getting ready to install the 280zx seats. only things left now are the intercooler and radiator and it's ready for the road........well actually for it's first drift comp in 3 more weeks.

Did you take any pics of the engine mount work you did, and did you say that the transmission crossmember bolts straight up?

I'm not sure if I was too clear. I meant does the RB mount fit straight onto the D21 body or do you use the D21 crossmember?

the HB has a fs5w71c transmission so there fore the fs5 used on the rb20 in the pics will bolt up to the HB crossmember. If your talking about an engine crossmember there is none. peace.
