Re: SR20 Engine Swap into a 90's Era Hardbody(D21)
I'm currently swapping a SR20 into my 97 hardbody. I'm doing this swap on a budget and to say the least its been quite simple so far. bought the engine/trans/harness/ecu, swapped SR bellhousing to hardbody ka trans tailhousing. i got the engine and trans stabbed with the oem sr20 mounts but the engine sat too high in the front and the trans sat too low and all the while it sat too far back. the trans cross member was able to be bolted about 1.5 inches farther forward for it has the hole for the V6 package. AS OF RIGHT NOW, i sent my driveshaft out to be lengthened by 1.5" inches, got the engine and trans level using a '72 Dodge Dart mount and the oem sr20 left mount and added an 1.15" extension to the trans mount to raise it up. Also had to add sway bar spacers in between frame and bar, dropping it .5 inches to clear the front sump oil pan. Would like to find some one out there that has ran a/c in there truck, I live in south texas and DAMMIT I NEED A/C! AND ANY WIRING INFO WOULD BE A PLUS! got most of it situated, just have a few BS questions. i have done a bunch of little thing preping it for the road. will post pics soon. any info relating to the swap thus far i am willing to share and would also enjoy info from someone who has done this before.

Re: SR20 Engine Swap into a 90's Era Hardbody(D21)
Hi, I have a 1986 d21 swb that had a z18 and column shift 5 speed , I blew the head on that and swapped in a 1997 s15 sr20de and gear box. Not the easiest swap I've done , but ended up with a useful truck with a good turn of speed . Surprises the hell out of the mini guys when they can't get away.
The engine position ends up being a compromise, you can get it to sit at the sr angle altho a little high in the front , needs to clear the drag link. I reckon a notch in the sump would be worthwhile to get it down another 15mm or so , but it runs fine as it is. If anything it messes with oil levels in the gearbox, overfilling a bit helps this. Has no ill effects on motor so far ( I have driven it hard, no worries).
Be prepared to cut and weld the chassis mounts for the engine .I used the sr engine mounts and rubbers. Gearbox xmember comes as far forward as you can and up 30mm in the centre. Cut a hole in the floor for lever. ( I notched the bench seat as well, gotta have 3 seats!) I am using the sr lever in backwards and bent a bit, works a treat. Shorten the driveshaft.
As for the little stuff ..... speedo- use the d21 cable and reroute thru other ( 4wd i think) speedo hole to get cable on right side. I shortened it 50mm to fit nice. A VG30 or early skyline gear drive into where the sensor sits and your done.
Some plastic adaptors for the different heater hose sizes, throttle cable lines up, fuel lines are easy to line up.
I used the sr headers bent and cut to suit and built a 65mm exhaust , with two large mufflers its pretty quiet with good torque and power.
Running standard ecu at this point on a cut down loom. No Problems.
Custom built intake....etc etc etc
A good swap if your keen and a really good intro to f..ken around with cars and hot rodding cheap cars. It weighs the same as a s15 handles and rides 10 time s worse (Part of the fun) but goes hard and makes a good noise. There are also two driveshaft loops as per New Zealand certification rules...
Hope this helps

Re: SR20 Engine Swap into a 90's Era Hardbody(D21)
Very seriously considering this whole SR20 swap, the bloke told me to think about it and had no rush but, got offered a package the other day from a s13 drift car, he just rebuilt the SR and is going for a V8 upgrade.
So it isn't just the SR either, what I can remember from the phone call it has heaps with it, like.. uh, wiring, something something, tail shaft, r33 gearbox.. uh, garrett 'some number' turbo, forgot what kind of intercooler, exhaust components.. s*** I pretty well forgot after he said we'll meet at the pub on Monday for a beer and talk about it, he will have the full list written down for me then anyway!
I've pretty well just pulled my KA out anyway, and haven't yet spent anything on that.. hmm...
Opinions/Thoughts???
