Cutting a long story short until now. I've gone from this '95 Evo last February, not running, in poor condition and needing more work than I really thought.
To a rebuilt stock engine and budget paintjob by the start of the summer:
And then in November the project started to make a car I can have a little fun with:
And most recently the car is all but finished:
5-7 days and it might be in a position to start up and possibly even move. Fingers are crossed.
Specs are roughly:
-Mahle pistons
-Scat rods
-Eagle 4340 crank
-fully ported head by Motorworx Engineering
-stainless valves, FP springs and retainers
-removed balance shafts
-Ported oil filter housing to drop oil pressure under high boost
-Throttle body half shafts removed and ported intake manifold
-custom 70 MM piping (giving me a total piping length of under 1m)
-Treadstone Vertical flow intercooler with fabricated mounts
-JM Fabrications top-mount manifold
-Holset HX-40 with a .84 Garrett exhaust housing
-Twin 38mm XS Power wastegates
-Synapse Engineering Synchronic BOV
-custom 4" intake with K&N filter (to be upgraded to Blitz stainless SUS filter)
-custom 3" downpipe, and 3" exhaust, with Blitz muffler, and Apexi mechanical valve
-OS Giken STR2C clutch
-stock 1.5 way plate diff
-walboro 255 fuel pump (re-wired)
-850CC fuel injector clinic injectors
-Sard Fuel pressure regulator
Winner Racing custom-sized aluminium radiator
Suspension & brakes:
Cusco coilovers
17" Dunlop Star Spec tyres
Mazda RX-7 brake calipers fitted with custom bracket to redrilled Nissan Altima rotors
Evo VI master brake cylinder (better for the larger calipers)
Hawk HP+ brake pads at the front
Project Mu B-Spec brake pads at the rear
Interior:
Integral Knock Meter
Billion VFC-Pro fan controller
Blitz SBC-iD boost controller
Blitz Power Meter
AEM Uego wideband
ECMLink engine management
Think that covers most things! |

Damn ! That's a big motherfokin' turbo 
Very nice job on the engine, piping and manifold. This is gonna be a real beast
Does the stock gearbox usually cope with these kind of setups ? |

Stock gearbox will hold up to mid 600bhp. My aim at the moment is somewhere above 550. The twinplate is only rated to 600 too so I don:t want to be having to fork out on a triple plate any time soon! Meth injection is being considered in the future and that would get me over the 600bhp mark. Axles are good to about 700 I've heard and the transfer case has been known to do a 1/4 mile in under 8s! But I am making sure I've got a spare mission, transfer box, driveshaft etc a I am at the point they start to become consumables!
I'm into drag (the racing, not the lifestyle) and will be aiming for very low 11s or if I can nail the launch maybe sub-11s in the 1/4 mile. We'll see... |

It's alive! Only just though, and what a mission it was to get it there. What I thought would be just an hour today ended up being 12 hours of constant work without any breaks on it. The battery got connected up relatively easily and without major incident, and that was where the simplicity ended.
When that was wired in I was able to connect the battery and see if everything did. My boost controller, fan controller and wideband did, but they stayed on when I pulled the key out! Realised I'd tapped into the wrong wire under the dash so had to redo that, and then a few other bits of wiring.
Got the oil line re-cut and welded and got that fitted up after much messing about. Problem is that the drain line comes dangerously close to the manifold. While it's not gonna be a big issue at idle or doddering around, I probably wouldn't want to do any full power runs in it when exhaust temps inside the exhaust manifold are 1600F or so. The flanges are aluminium too which have melting points of 1200F. They should be ok but I might need to extend one of the lines so I've very little rubber line close to the manifold.
Got that fitted up though and the car filled with oil. Did the same with coolant, after dealing with a coolant leak and realising the radiator is sealed with no drain (my bad... forgot to request that!). And then it came time to test it again. I wanted to test the fuelling to make sure there weren't any leaks after changing to the new FPR. Activated the fuel pump and the pressure gauge went up to 46psi monentarily, and then dropped to 10psi and stayed there. Strange. Tried again and only 10psi again. Checked voltage to the pump which was fine and the pump was definitely working. Changed back to stock fuel pressure regulator and no change. Tried firing up the car and it would sometimes try to cough or start for a split second but would then die again. After an hour or so I pulled the Walbro out as I'd assumed it was bad. Had a look and it turns out when I put in the Walbro in I hadn't transferred over the plastic spacer that goes in before the o-ring on top of the pump itself. We replaced the stock Evo III one with a much better Evo VIII 3-level o-ring and put it all back in.
Tested the fuel pump again and had fuel spurting all over from a couple of leaks near the FPR. Took a while and new hose but sorted those out too. And then I turned the key finally and it started up.
For the first time in almost 4 months it was idling. It has thrown up a CEL which I need to work on diagnosing, but will look at that tomorrow after work. I think it's something to do with the speed density setup I'm trying to get working. We also have an exhaust leak at the turbo-downpipe v-band, and we broke an older v-band clamp further down in the exhaust, but those can be sorted out quickly enough.

Congrats Dave ! 
Looks like you've earned the right to be really happy when it runs for good |

200hp at idle... you know you're making real power when you can do that!
A little more work done on the Evo tonight. Did some more playing around with the ECU and got rid of a nagging check engine light from first startup. Tough to confirm, as I've got an unclamped v-band upstream of my wideband O2 sensor, but idle AFRs seem to be bang on at stoich.
Even more promising is my cooling system. Put in my Purple Ice (to increase coolant surface tension) and bled the coolant system tonight. Found that even with the fans unplugged so they wouldn't come on the car was keeping cool at idle. Temps were going up to 80C and then as soon as the thermostat opened they were dropping back down to mid 70s. That's a hugely encouraging sign that the cooling system I've got in place is going to work pretty well. We tried revving the car and warming it up and couldn't get the temperatures to rise above the low 80s. So all good stuff.
All I need now is a replacement 3" v-band for the one that broke and the car will be good to move again. Typically, I don't think they are available on the whole island, so I'll have to get one sent from China or the States.

And the finishing touch to the car: a carbon bonnet. Don't think it's any lighter than the stock one, but that carbon definitely looks the part.

The car got the full treatment today: wash, claybar, polymer coating, steam cleaned interior, engine bay clean, and pretty much everywhere else you can think of polished. As you can guess from the pics, I'm pretty pleased with the results.
Thanks to Chris Willson at http://www.travel67.com for the last photo too - really pleased with how mean looking that's turned out.

I would love to drop it and the Cuscos are adjustable. But thelip on the bottom of the HKS Kansai front bumper sits real low, and any lower would really mean I have to take a lot of care when daily driving as if not it'd be ripping off in no time.
The car's now almost finished with its tune. I'm boosting 1.75bar and both meters I have are saying that I'm making about 560bhp. The only thing I need to fix is spool - it's spooling a little slow 4,800rpm to full boost, at the moment but this weekend I've found that almost all of my injector seals were leaking so I've ordered a full set of them. Once that's all sorted out it should be nice & quick. |
