Well guys here is a link to the motor thats going into the DX and its build
http://www.redpepper...showtopic=49596
anyways i picked up a Red 1987 CRX Si that had been hit in the front end and had a bit of damage, Also the engine had 3 bent valves on the Head and the camshaft grinded off on the journals.
So flash forward i go to VA and pick up a new motor and transmission from a Dude on here that was selling it, the motor was sitting for 3 years in a shed, rings were stuck in the block but really i only needed the head and it was in excellent condition (head i ended up using)
After a stream of bad luck with this car i end up finally getting a D15a2 Block getting it punched over 60 and using 88-91 CRX si pistons,
Came across a MINT!!!!! almost rust free CRX DX yesterday that requires Little To No bodywork all the plastics are MINT and in perfect tact and i just feel that the body is a much more solid platform to use than that of the CRX Si,
so starting today at 1:00 i am going to get the CRX DX and begine stripping the CRX Si to nothing but a Shell and then proceeding to swap everything over to the DX so i will have a Si with the body of a DX
Also with the car the guy is throwing in a D16a1 Blacktop axels spindles ETC ETC everything (he was going to swap it all but needed the FI CRX)
so i will either Sell the D16 or save it for a build later on
wish me luck and i will keep this thread updated as i go!
if you have any input or advice PLEASE feel free to share

If you plan on swapping over the Si skirts, I'd gladly pay handsomely for the dx skirts and/or front bumper cover. Always love to see the builds.

You are going to find there is a difference between a Si and a DX. Little things like the welded on fuel filter and coil brackets are different.
I want to know how that engine is going to run. I am working on a similar one for my "new" civic.

Very interesting as I am also probably starting a similar endevor. I'm getting a rust free HF and building my spare D15a3 and ripping the guts out of a wrecked 87 Si. Keep me informed on any little problems you run into and ill do the same. I hope its as straight forward as I think... We'll see. Good luck!

I stripped a rust bucket SI once, and the interior was the hardest part. The big rubber plug in the firewall pushes through and is part of the harness itself. Just unbolt/unplug everything.

just an update for this thread!
i got the Red Si pretty much completely stripped down to shell.
I took the fuel pickup out of the Si tank and then i pulled the rear wiring harness out of the car, pulled the fuel pump out of the car, and all the fuel lines out of the car, Also Man was pulling the dash wiring out an absolute pain in the butt lol.
But as soon as i can get the Si out of the garage and into the hands of the crusher i can move the silver DX into the garage and start the swap process. I already have the interior pulled from it though

well, last night i ended up getting the full interior pulled out of the CRX DX and as soon as i can get the Red si out of the garage i am moving it in,
If someone wants to come get the red si and pick it up i have title in hand and you can have it if you just will haul it off. Otherwise i am taking it to the Junkyard to be crushed. i am located in WV

Update*
car has all 3 Si fuel lines swapped into it (terrible job to do) lol Si main line was rusted a bit so i took some POR-15 to the outside of it to prevent further damage everything bolted right into place but you have to use the Si clips that hold the fuel lines into place (which should be noted) Also the Si main line and the DX main line are IDENTICAL in size except for on the pickup, there its a much larger line that goes into the 5/16th line so other than the high pressure fittings already being on that then it was basically pointless to change it out IMO, The rturn line in the Si was much LARGER.
Fuel tank has some (looks to be) rust on the inside cleaning that out the best i can and working from there right now.
