It was $1 reserve on trademe ha, but no bidding war started and that was the final price Paid for half my ticket to WA ha.

I sold my full 260 conversion for 250 bucks. God some people ask some crazy prices for them.

Went out with motosoc, just a track intro kind of evening. Gooooood fun. I love having hooked up brake ducts, fade very minimal. And I discoved e30's have no trouble drifting the whole sweeper in 3rd (not show (off) drifting) And also found out that oversteering gets you black flagged ahaa.

My suspension mods start very soon, and I've added a pic of the slalom that shows that stock suspension is just horrible. 25mm front sway bars win.

Anyway some pics. Great evening. These old bimmers are so much fun, great balance and grip.

Weeee, foot flat with good tires in 3rd

Yuck. And yuck photoshopping sorry.

Hunting... Making him watch the mirrors ahaa

Next lap

Piccyture of the Mtech2 spoiler??..

Yeah I was concerned about that.. thought a well placed wastegate would solve that though. .84 is too big for my goals. Why is there no .74!?

Forgive me but this is all in retarded imperial, only cause garrett measure their turbos in that system. Too bad they make awesome turbos..

At 7000RPM the 2.5 M20 flows through 308CubicFeet of air per minute. (my intended redline)

On 10psi at 85% Volumetric Efficiency (single cam goodness), the turbo must flow 38.2 pounds of air per minute. At the torque peak of 4000RPM, 21 lb's per min. You idealy want boost before 4000 then to actually make 2g on a new garrett worthwhile. Or less if buying used ha.

Spending hours staring at info and turbo graphs, I came to this conclusion for the set-up I'm considering

GT2876 with .64 exhaust housing

Calculating exhaust flow rates see that thing spool before 3, easily, and top out right around 7000RPM for a shitty M20 2.5 with good boost management and the right wastegate size. (link G4 of course, my friend works at link ) And that works at 1 bar (14psi) and 7 psi, because as you increase the boost, the limit on the graph heads diagonally up to the right, staying in the efficiency islands (Around 68-72% depending on boost) Anything less than 60% is bad, and those maps only show 65% and above. So, heaps of room.

The next step is a GT30, it'd be doing less work for the same results, but the response wont be the same as this thing. I've had a nice internet chat to a guy from e30tech with a GT28 (a rare person who doesn't put a big f**koff Holset or GT35 on a whatever-they-could-get-their-hands-on turbo system) and says at anything over 2.5-3000RPM, it's like a beautifully smooth monster of torque.

I'm doing this ^ or S50B32 if one pops up. *DIBS*

Pictures for anybody who is like 'WTF R DEY TALKIN ABOT?'

Larger percentage of glue than actual metal in those kits

Koyaanisqatsi

FM901 yes, and I run a spare set of basketweaves on my e30 with 4X901's for summit rd runs and also had 4xDirezzas on my car when I got it in October last year. I know which tires I trust on a cliff road. The 901's have fantastic grip and heat up so well. Direzzas are very very dodgy in the rain.

I run Pilot Precedas now, downhill braking with these is a caliper flaming affair.

My old boss used to be the South Island Rep for Michelin. He currently owns the rights to distribute Michelins in the South Island and does so out of Advantage Tires. That's inside industry knowledge

Direzzas were made because the predecessor to them had more grip and took longer to wear out. Gotta make MONEYYYYYY they said.

Anyone who has done 6th form maths knows that.

Oh wait, it's for Americans. Makes sence. Lots of pictures.

That was a fantastic video, thanks.

Love how the Skyline just gets destroyed, then Tsuchiya nearly dings the AMG twice ahaa, and that the M3 sounds the best and has no understeer compared to the others, especially the AMG haha.

Why have I always thought the Tii had a turbocharged injected engine?

I'm so confused. I swear there is a 1970's turbo BMW... Google will know. Or someone here.............

9500 redline? sh*t, must be a Spoon engine. What a bargin!!!!!!!!!!111!!111!111111111!11

Go slicks! Go no driver aids! Go Monaco! Go Kubica!

*Oh, and Go bringing back the Nurburgring Nordschleife!

I wish.

Because of this 'waterhammer' I always think someone is running up behind me when I get a drink late at night ha.

No suggestions sorry.

FOR SALE THREAD FAIL!

The jappas have a huge 4 cyl crankshaft spinning at 10000+ rpm with all it's gyro forces to pull the bike up, it's the turn-in on them which sucks compared to twins. The bmw bikes handle amazingly because of the front-rear boxxer crankshaft. No gyro effect in the corners. And you can hold yourself up at traffic lights with the torque roll ha.

As soon as I can I will be buying a gsxr600 to race. Probably after uni of course..

Yeah christ it's horrible, the prices I mean. I got my Eng textbooks 2nd hand woot, saved hundreds..

Mathematical Analysis 11th Etd and a GT2876R Garrett Turbo.

Yeah it is, a massive sound cannon haha.

I can't believe most people are trying to sell zxr's and cbr's for 6 grand.. They are nice bikes and all. But so much maintainence is required and they are getting very old.. 180hp per liter engines don't last forever ha.

What full sized bike are you looking at??

Little plastic diddle of a thing breaks off, must replace whole indicator. I could not get the unit open to replace just the diddle bit..

Read and research forums, mainly e30tech, for 6 months. Then put together a parts list.
