Update New clutch Ecu swap out of the question at the moment. Plug on harness is a 3 plug all 4x9. very unusual. So would have to trace all wires back to ecu and fit wire in harness. not keen to do So ill look for a gc8 harness for an upgrade so a link will plug in. So took it to dyno to sort fueling out. You see the car doesn't even get that hot at the track Say tops I've seen is 76 degrees manly because of the richness of the fuel. 9.60 So about 10kw down there. So mucked around with it and got a better afr and ended up with 138 at wheels on 9psi. I wanted to turn it up to 12-14 psi but they didn't want to because they didn't new the engine. But I'm fine with that. missed the first round of the summer series here because it was pissing down. Don't do rain, no fun for me and a waste of money. $270 entry plus petrol, NZ 100 octane $3.20 ltr Anyway I need to go see a friend of mine and talk about setting up the wheel alignment to force the car to turn better without losing the rear end. He's a racecar fabricator plus has work in wheel alignment shop setting up racecars. Will start from there and see how it goes I'll work on getting some videos up at some stage for ever one to have a look at. Have a good xmas all

Been a while from last update. Sorry Took the brat to the track for the last round of the summer series. At this point I was coming 3rd and with all the teething problems you get from a new build. Mainly with the boost soleniod not doing what it should. So just put a manual tap on it and added a 02 gauge to keep an eye on fuel ratios Started with 6psi qualifying then to 8psi for first race. Starting to go like it should but noticed it slipping the clutch a bit at the end of the race. Only 9.6 on the 02, so really rich so cranked it to 10psi. No good the clutch was pretty much stuffed on the warm up lap. New clutch only done 2 practice events which the car wasn't even going propalley, 2 qualifying runs, so just warm ups and a fast lap. 5 of the 9 races. So disappointing for a upgraded clutch, but was running 3rd out of most corners so lots of torque. Will have to save up for a really heavy duty one. But anyway just an update for those who are interested in whats been going on.

Took it to the track for the clubs summer series. Upgraded the front springs to 450lbs. It made a difference, way better under braking and better through the corners. Still not quite where I want it. Unable to really push it coming into corner but more steady in the rear than last track outting. Results Qualifying , the little sleeve of rubber that goes over the throttle cable slipped down and got caught in the throttle and jammed it on full throttle. First race made up a few spots 2nd race reverse grip got more confident with the handling ended up in 3rd but the 2 guys in front of me broke out, so 1st for me. 3rd race handy cap based on lap times. Flag drop per group So might be 5 second behind the slowest car the next flag drop and maybe another 5 second to the next flag drop and so on. Slowest first off and fastest last. Got 1st in that race but broke out on the last lap by 300s of a second Now it not fast yet and I'm in the slowest class, but under full boost I can feel it will be allot quicker. Problems Apart from the bit of rubber throttle jam up only one other problem. The same as last time. The boost fluctuation. jumping between 6 and 10 psi under load. Sounds like the clutch is slipping. We changed the boost solenoid but didn't fix it? Check for leeks this weekend Anyway a fun day had by all

All sorted We had plugged a injector plug into the crank plug O well moving on with handling stuff

So update after todays work The cam and crank triggers are the the same between both bg5 and sf5. Have power going to coil pack Have checked coil pack and tested it. working fine. Cranks over easy but still no spark. Got good earths, added a few more to make sure. checked all plugs Bit off a loss now. Didn't check igniter, don't no what im looking for ha ha ha Yea i only have iphone on a prepay system do not connected to net to post pics from track but my wife made a instagram account and put something on it but i dont no what But next time i'll get some shots and a flick or 2 Thanks doc

Thanks el_freddo The forester has a td04 turbo on it But well have a look today at other stuff

How's it going We have had the brumby at the track a couple of times now with mixed results. Since the change to the sf5 engine out of my forester no engine problems other then running on gate. (6 psi) And the handling need some work. but got a plan for that. Hooked up boost control solenoid and got boost jumping up around to 5000 the solid 10 psi. Got a fix for that. But seems really slow for a turbo 2.0. Down the back straight its only getting to 165kph which i would expect it the be 180kph with say 190hp? My honda with a b16b does 185kph with 185hp. There's not push into your seat. So the handling we are going to run a stiffer front spring and toe in the back a little to force it to turn in better as I can feel the back wanting to brake loose. Now the problem is we decided to swap out the 1996 sf5 300000km block that through a sparkplug out the head for the 1996 bg5 200000km block which is in way better condition. Swap everything over, blocked up unused holes, wiring etc. Problem is it won't start. Now my guess is that the crank and maybe cam triggers are different? Any ideas Thanks doc

Thanks man The motor is from my 1998 s/tb forester. Its seemed to pull the trailer no problem. The turbo looks like a td04 but will have a better look in the weekend. Also will look into the boost controller. As you say must be an issue for it to be blocked off. And i do have a forged block sitting at home for a later date when I get the the handling and braking tuned a bit more. Definitely needs a front rear brake bias system. maybe a G16 turbo?

Update Took the car to a track the other day Went pretty good, just a few little things to work on. Brakes need sorting out, bias mainly Found that the tyres don't get that hot (but only did 3 laps a run) And it seemed down on power. There wasn't much kick when you put your foot down. 300000km engine might be the problem or only running 6 pound boost. My xsi teg is 14 seconds quicker a lap noticed that it seems to be setup to run on gate pressure only. The wastegate solenoid valve hose it cut and blocked off Hose plumbed from turbo to wastegate only. Should be running around 10 pounds. Bit anyway stuff to work on

Update Twin turbo engine out, wiring out. Forester wiring out in 2 hours, engine out and in brumby. Made a A frame type engine lifter on wheels with a electric hoist. So easy to put engine in and out. Just finishing wiring Should be easy now single turbo and manual wiring. And now we can tune it too. Thanks doc

Hay all Don't no if you have seen my build Brumby with mid mount bg5 engine. Just having a problem with the vss wiring. So the engine and wiring is out of a 1996 bg5 gt legacy. Now on the wiring harness has a plug for the vss. Q: do I still use that plug and plug it in? Also we have removed the TCU as prescribed and now are trying to wire that up. But all I read is that you wire it to the vss? (confusing as it has that plug) So I no we need a 5volt power source to run that vss, So we nick a power wire, earth wire, signal wire from the tcu plugs. But what now? Do i need to wire them to vss or dash or? The good news I have a ecu pinout for a 1997 gt legacy (thats helps alot) but no tcu pinout. Pin for me are looking from the wire side. All comments welcome Thanks doc

To help everyone with the imposable mid 90s bg5 pinout. Can't tell you who I had to sleep with to get this info, But in my world there are no secrets. These are 1997 legacy gt twin turbo Hope this helps everyone and pass it on for my 1995 bg5 the info for the pinout was looking at the wire side. Doc

All good here fuel flow rate 15oz in 7 seconds The aeromotive fuel system I run is rated for 450hp na, so all good there. Now a surprise to me I managed to find a BG5 1997 4 plug pinout. It seems to match what I have. Check with other sensors on engine. Now hopefully it will rev over 4000. Cheers all doc

Thanks all we may have pinned the wrong pin on the 4 plug ecu. It is extremely difficult to find anything on a 1996 BG5 T5 ecu pinout. heaps of 1994-1998 pinout and single turbo pinouts but trying to figure out the right pinout of the ecu to think it a manual, no go so far so far the only 4 plug ecu pinout we can find is connector B58 pin 10, Doesn't match our ecu and the only other stuff is from a 3 plug ecu connector b135 pin 25. no go again O well keep looking

Thanks man Hope the above post made sense. Half a bottle of bourbon down
