Hello everyone!
I thought I'd put together a build thread finally since I'm getting towards the end of college and starting to have enough money to fix it up right. Also, it will help keep me motivated to do good work knowing that the vigilant eyes of Zilvia are watching.

My goals for this car are to have a responsive 350-400whp, make it light and make it very well handling. Basically I would like an all around fun "driver's car" that will be at home on the track/strip but still see significant street time.

I've been around the 240 scene since summer 09 when I graduated high school and picked one up to go along side my DD, a Volvo S70

So here's the 240 coming off the tow truck

Here's the reason why I needed to tow it. It came like this...

A valve popped loose, and the previous owner got fed up mid repair so he sold it to me for $3500. What I got for that price was the car (obviously), an SR20DET with an S15 turbo, Koyorad radiator, Greddy FMIC, Greddy Type-RS BOV, Greddy turbo timer, an incomplete "Freddy" manifold full 3" exhaust, ACT 6 puck clutch, ISIS short shifter, Nismo slave cylinder, z32 VLSD with 4.6 final, Megan coilovers, Q45 Brakes, z32 maf, 550cc injectors, a "tuned" SAFC II and an extra set of cheap-o wheels that I sold for like $300. Pretty sweet for $3500...

The interior was nice and clean too

I tore out everything in the rear though, who needs that?

I decided I wanted more power than an sr could provide so I bought this baby and its 1.6L of Honda fury!

Actually... that was for my girlfriend's civic whose piston blew through the side of the block. So yeah, I just got to work putting the head back together with some new goodies. I figured while it was all apart I should port it a bit, solid lifters, Supertech dual springs/retainers, new guides, new seals, new valves, Greddy RAS, Tomei Poncams; ya know, do it right. Here are the cams, lifters and adjustable gears which I later exchanged for Jim Wolf gears which do not have sliders that can break free and ruin valves.

Here you can see how I ground down the slight lip under the valve seat which reduced the area of the opening for the valve.

Here you can see how I ground down the casting marks.

And here you can see how I just generally smoothed things out and brought the divider in the middle of each runner to more of a point.

Finally, it was time to assemble it all which was very tricky since I wasn't the one who took it apart. I could now do it blindfolded though, considering how many times I have had to take this thing apart...

All done!

I took it out for a quick drive with my dad but it turns out we forgot to tighten the three downpipe bolts and it worked it's way loose about a mile down the road next to a corn field.

Rather than accept fate and call a tow truck I got inventive and shoved a corn cob above my muffler. Pressing the muffler down brought the downpipe up because of the exhaust hanger in the middle. Think "see-saw"

And here's some rust in the footwell I found shortly after. I have a growing rust problem that I have yet to properly take care of but I'm about to buy an angle grinder and mig welder so it's all getting cut out, welded over and painted soon.

Next on my list was some under-dash wiring for some new gauges including oil pressure, boost, wideband and a failed attempt to install a little 52mm tach since the sohc tach in mine doesn't work with the SR. Also notice my new leather nismo shift knob to replace the pos Autozone one that came with the car and most importantly the Haltech Platinum Sport 1000 ECU that I would be tuning myself.

Got a new tubular manifold, Nismo FPR and z32 BMC too

I also decided now that I had the Haltech, that I'd run LS2 truck coils because they're awesome and I can

I tuned this all myself on a side street for a few days off and on and then on a dyno for an hour. AFR's were pretty much rock solid under boost and I managed 293whp/299tq on a hot (94F) day. Pretty good for an s15 turbo so I was proud of my tuning job. Plus I could tell my little bit of porting work helped too since my s15 turbo could barely flow enough to hold 14psi. My engine was really sucking in some air and the turbo couldn't keep up.

Well that's enough writing for now. The story of my numerous valve issues, suspension goodies and a gt2871/S3 cams/Freddy manifold upgrade are coming up next
