slowman's EG8 build - D Boost!
Well here we go. Picked up this car in November 2009 I think. When I got it, it ran rough, thought it was plugs or timing but I did a compression check and cylinder one yielded a whopping 5psi of compression so that was the problem!! So that's when I got in touch with MrM3 to purchase the old heart out of his Wagovan project, a D15B2. (thanks!)
So I was initially going to just swap it and roll with it, but I got the itch to build another boosted D Series because the last one was a lot of fun and man, it's been awhile since I've built my own car instead of buying other people's stuff. So that's what's going on with the project. Boosted D15B2 from 89 Wago, force fed by a Mitsubishi 14b turbo, and a GM ECU and Speartech harness will be telling the engine what to do, and when to do it! Onto some pics:
Here's the 4 door, got the rear quarter cancer for sure:

Picked up this FMIC off Seth (thanks!):

Got some fresh Honda hardware. Gasket for HF manifold, 2 exhaust manifold studs to replace the 2 that are broken off in the head, and 2 nuts:

Picked up a cluster with tach since the original one doesn't have one. Yes, it's for an auto because I wasn't gonna pay $120 for a manual one. I just Sharpied the PRNDL letters out black lol. Whatever, it works. And also swapped my speedometer so I retain the actual miles to my car:

Removed stud 1 from head:

Installed the 2 new studs and finally used this new exhaust manifold gasket that's been in my garage for 4 years. Glad I didn't throw it away!

You have to drill the threads out of the two holes that face the front of the car to work with the adapter plate. So I did that, then you use two studs in the adapter plate that fit through the holes you drill out, and secure it with 2 nuts:

No one sold studs for my thread pitch, so I bought two bolts and hacksawed the heads off, creating studs:

The exhaust housing presented a problem, not enough room to fully thread and tighten a nut onto the stud, so out came the Dremel:

Finally, after tracking down the proper SHCS bolts and stuff, I was able to put the turbo/manifold/and adapter plate together and onto the D:


The DSM exhaust housing is just about perfect placement to fab up a downpipe to exit out properly.
And thanks to zach_oaks on here, I bought his complete intake mani/tb/fuel rail that he had for sale in his thread. This wasn't really necessary as I already have one on my car, but it will make the swap go much more smooth so it can already be done and ready to throw in, instead of taking mine off and putting it on. One of the studs that holds the fuel rail on was jimmy-rigged with some washers for the spacers and a bolt, so I got onto Majestic Honda site and ordered a new stud, proper spacer, and nut tonight.

So that's all the pics I have as of now. As soon as my fuel rail hardware comes in, I will be installing the DSM 450s I got off Joey (thanks!). Also ordered new oil pan drain plug and washer cause this one seems to leak a lot so that'll be in soon too. Also ordered a Go-Autoworks thermal intake manifold gasket and the Pro oil feed and return lines. Should be here by Friday! (http://www.go-autoworks.com)
Next up is just clutch, charge pipes, and seeing what's up with the harness and ECU. Think I still have one from when my dad mocked it up for the old EF, so we're gonna see how usable it is tomorrow and such. Will keep this updated regularly! Thanks to all those who have helped so far and thanks in advance to anyone who does in the future!!!

Got oil feed ran. Need two bolts for the oil drain though to attach the flange with AN fitting. So getting those tomorrow then oil pan will get modified and ready to go. Put on the Go Autoworks thermal gasket too. Also ordered my Comp clutch

I'm thinking about doing a Ferio project but with a D16 VTEC boosted. You gotta let all us know how it drives!!
