JDM Evo 7 from Australia
Hey dudes,
Bit of a build from DOOOWWNNN UNDER.
This is my second Evo 7, and third 4G63 powered car.
- First was a 1995 2L GSR (Basically a poor mans Evo 1 chassis) with a VR4 based 6-bolt motor, Evo 1 RS short ratio driveline, GT28RS turbo, Autronic etc. Was nothing special by todays standards with only 182wkw on 18psi, and 12.6 @ 106mph. At 19 years old however, combined with the gearing, it was a formidable street weapon taking down alot of much higher powered cars on the usual Thursday - Sunday night gigs.
- Second was a Evo 7 with some pretty nice fruit, PFC, 8MR turbo etc. which made 213wkw on 23psi.
Again I pounded the daylights out of the car, which never gave me an issue in the time I had it.
After doing the responsible thing of selling, getting married, buying a house etc. etc. etc. I came across the current Evo 7 by a bit of an accident as I wasn't intending to purchase another car at the time.
It was a little rough around the edges, had had a quick and rough rebuild a few weeks prior to my ownership by the previous owner as it had broke the ring lands off of several pistons due to a crazy aggressive tune in Japan which wasn't really going to work on anything less than Ethanol or C16 out here.
Mods at the start were cat-back, HKS intake and grenade tune.
Added a front pipe, 4-bar map sensor, MR Bov, 3-port and retune. Quickly learning I had run out of fuel on the stock pump.
Replaced the pump and cleaned up the tune.
The car stayed like this for a few months, copping a flogging where-ever possible!
By this time the track bug was hitting and since this car wasn't in finance wasn't it finance it was full steam ahead.
Thanks to Pete for the rims and semi's to get be started with.
By this time E-Flex was rolled out in Newcastle early 2011, so injectors and a retune on the love juice were in order.
After retuning for a while and learning lots about ethanol in the same process this is where it was left for a while again to enjoy.
Car once again proceeded to cop a hiding for ~18months on the street at Powercruise, hillclimbs and various tracks, also receiving a few sets of wheels along the way.
Tarmacs, which my mate decided looked better on his E4 shortly after I got them. lol
Then replaced with OZ's
Killed some pads and discs in the process.
Small vid of a local hill-climb in King Edward park.
Another of the car being enjoyed how it is sposed to.
Then a few weeks ago, late May, early June, I went to a track day at Eastern Creek with CSCA.
Chasing a local lad with a pretty serious S13 on the North circuit at the Supersprint, fourth session of the day and starting to get the car dialed in nice after being off the track for nearly twelve months.
Went out with 1/4 tank and only being 5-6 laps figured i'd be fine as I have run down to the light at Wakefield plenty of times.
3rd lap at the top of the straight the engine light flashed quick a few times (big big detonation) backed off, checked the boost and wideband, all good.
Got back into it, car pulled fine and boost stable at 25psi, AFR mid-high 11's.
Went through turn one still hot on the heels of the Sil after the braking zone, car felt flat and missed again, AFR 13-14, then back to 11's. Being in the red zone I just kept into it.
Back through the back half of the circuit up and over the flip-flop all good. Back straight and major miss and engine light again, followed by a muffled 'bang' big puff of grey smoke out the back and running on 3.
Limped it in and figured it was pretty terminal.
Jumped out and no oil underneath thankfully, oil all over the rocker cover having blown out from under the oil cap!
Pulled the plugs and found the culprit, other three were perfect, one was hammered.
Initially thought I had a injector fail on me as the damage was pretty catastrophic on cylinder 3, after speaking to a few more experienced Evo guys, they had all done the same thing themselves but on 98 you get a bit more warning of running out of fuel.
Major fuel surge causing the pump to suck air and leading to minor lean-outs on that cylinder as it fills with air the most on a stock intake, 1-2 laps worth at 25-26psi was obviously too much in the end.
Pretty upset with myself after working out the issue a week later, but kind of ironic as I had a block at the machine shop getting made up as a spare a few weeks prior.
Lesson of the day kiddies is to be careful, especially on E as the warning signs aren't purely obviously like 92 which will buck and kick when lean.
E will pull hard well into the high 13's, on a track where you aren't as alert to the motor and have a helmet on, its easy to miss the 'flat feeling' that a major lean-out on Ethanol gives.
Late last year I purchased everything to build the motor whilst the dollar was peaking and this forced my hand.
Dennis from Denstoj Auto Centre in Newcastle threw the motor together for me.
Build consists of:
- Stock crank
- 156mm Carrillo H-Beam rods
- 2.3 spec Wiseco 1400HD pistons
- GSC race shaft.
- GSC 5041 valve springs and Ti retainers
- GSC stem seals
- GSC S2 cams
- Tomei cam gears
- Reco head
- Mitsu head gasket
- Mitsu timing belt and seal kit.
- Carbonetics twin-blade clutch.
- ETS 3.5inch cooler.
- Plazmaman LICP kit
- Invidia dump (match ported by me)
- ToxicFab custom manifold to fit under a heat shield, coated etc.
- HTA Green with Turbosmart 22psi wastegate.
Everything back together with a reco box, new carbonetics twinplate and a few other goodies thrown in as it usually goes with rebuilds.
Threw it in the car on Tuesday, fired on the key and runs like a Swiss watch.
Time to give it hell for a tank on gate pressure, then turn it up and hopefully make EC in a few weeks.
Fast forward two weeks due to lack of time I have only driven it 100km
Bar has been raised a little in street trim now which i'm a little disgusted with myself as I am not one to look for numbers at all. sad.gif
Just that all my mates are building cars starting with 6xx and I don't like being left behind, which gives me bad ideas until the next time I hit the track which I then realise I struggle to harness 250. lol.
Should have 92 octane numbers by mid week (be happy with 250kw on gate pressure.)

Picked up some wheels I was planning on using as track rims, but don't mind the colour so might rock the orange/white theme for a while.
Found the limit of the setup on 92 last night, unsure whether its just the Jasma cat-back with neck downs in the muffler raising its head or whether its the limit of the setup.
It'll run through first and second gear at 28psi no dramas, top of third it starts to rattle a touch and forget the rest at 27+.
This run wasn't clean but not far off it with the odd 1-2 counts of knock, I dialed it back a touch though to mid 420's to allow for weather changes.
And just a little insight to my daily ride also.

Thanks for the props guys.
Have been stupid busy with customers cars, hence the lack of updates.
Bigger pump, ID1300 or ASNU injectors of some description will be going in, in the next few weeks, boost to ~30-32psi and call it a day.
Focus after that will be rebuilding the Brembos, install the braided lines, then handling in the form of some MCA struts, re-bush the car front to back and enjoy some road racing.

[quotelove your evo, rhd ftw....are your hvac gauges different than the u.s version?[/quote]
Yeah this has the RS2 climate control setup released in Japan. its a bit of a pain but what can you do.
In Newcastle mate, ~2hrs north.
Yep will be back at EC next month hopefully!
Been fiddling around with this cool feature for a few months now also.

Sweet as ride dude. You in Sydney i'm assuming?
Keen to see it munch up at Eastern Creek!
