An Example of Truly Impressive Turbo Engineering

[Colby Colbs]

They are in Greece Colby.

That's where my use of "some day" comes into play... manny moons, many moons away

Soo when that some day get here, should I book another first class ticket?

[600whp S4]

question is, how they've got all that money to start such an expensive thing?
what's their background?

Nice to see some real expensive work, finally.

there are people that spend 250K dollars on a single wrist watch. So this evo build is chump change for some people out there. Some of my buddies parents rebuild and have spare boat motors that cost $100K a piece and each boat has 3 of them X the three speed boats they own.... Its all in what your passionate about and how deep your pockets are!

My mind = blown.

I am impressed by things most impressive...


and especially enjoy the fact that its on 4bangers

Holy crap!!

I remember a drag turbo-integra motor build that was similar to this extent. It was a cnc machined 4.6L I-4 block based off a B18 engine. Everything was cnc'd from a single piece of billet and the car was RWD. Had 2 massive turbos and was supposedly capable of 3000hp and was subsequently banned from all import racing or something. Anyone remember that one?

I believe you are referring to Norwood Racing's Integra funny car. Definitely a beast and one hell of a one off engine.

Every now and then I come across something truly impressive. This represents some of the work of Extreme Tuners in Athens, Greece, and the name is no joke. Pushing limits requires funds and skill, and these guys have both. All they do is build and tune engines. The entire lengthy discussion can be found here (http://forums.evolutionm.net/evo-dyn...ne-2007-a.html), but unless you feel like reading quite a few pages of posts, I'll post the highlights here.

FWIW, this is some of what they've done:

2006 - N/A ford cosworth 4cylinder 16v engine 119cui: 416hp -11,900rpms
2007 - Ford cosworth 4cylinder 16v Turbo engine 120cui: 1280hp 47psi (custom triple ball bearing 80mm turbo 119lbs/min)
2007 – Mitsubishi Evo 8 4g63 4cylinder 16v Turbo engine: 1416hp – 57psi (custom quad ball bearing 82mm turbo 132lbs/min)

So, getting 700whp/L from 2.0L @ 8500rpm is no small feat, but what do you need if you get bored and want to shoot for 2000whp?


Cast Garrett compressor wheels (right) tend to come apart above 50 psi. CNC billet aluminum wheels (middle) are stronger, but why not be different and use your own CNC billet titanium (left) compressor?




You'll need a turbo big enough for the job, which in this case is a 108mm twinscroll T4 turbo, with custom quad ball bearing CHRA and 100psi capability.








To get enough airflow at 12,000rpm(!) to get the job done, you'll need a skillfully ported head, complete with titanium valves and copper-beryllium valve seats:








And you're going to need a set of camshafts to handle the rpm and withstand tremendous ramp pressures, so why not a set of hollow titanium billets with DLC at only 234 grams each?









And since there is no aftermarket rod up to the task, just ask for a set of billet mmcs-titanium connecting rods at 286g each. Rod/Stroke ratio is 2.07:






For pistons, a set of custom beryllium pistons with DLC fits the bill, and since methanol is the fuel, 13:1 SCR is fine:







A strong piston pin is needed as well:






Toss in a custom titanium billet crank:





A set of 9000cc/min injectors:




And since a factory 4G63 block probably wouldn't hold up, just CNC machine your own from billet aluminum:






No head gasket is used:




And to put all that power to the gearbox, one needs a suitable multiplate clutch:




Yes, it is smaller than a cam gear:






An example of very efficient turbo manifold design from one of their recent projects:






And last but not least, a dynosheet from this car, running 'only' 48psi and hydraulic cams:

a) *mocks* oooh...I like big turbos...ooooh...

b) What? No Inconel? tsk tsk...

c) Must be a drag racer since they CUT into the frame rail of an otherwise unibody chassis, which means it has NOOOO torsional ridigity. Not without a shitload of strut tower bracing, and even then, the chassis will flex like it's sheet aluminium.

d) That is NOTTTT efficient turbo manifold design. If they want to see efficient turbo manifold design, go look on the BMW N63(B44) engine. THAT is efficient turbo manifold design.

e) I wonder if they're using a Haldex or Torsen center diff/transfer case.

f) I'm also betting, no polymer electronics.

g) Awww....no carbon nanotubes for the drive/prop shafts?

h) Nothing like the leading edge blade design of the GE90?

i) No tandem, e-clutch packs for the DCT?

j) I'd love to see this thing try and take the Variante di Rettifilo. LOL.

Just about all of what you said is retard.

was in necessary to quote every single pic?
I hope you're trolling

[mike radowski]

Just smile and nod

[jo3y]

wow whats the price tag on that?

[mcoupemindy]

wow whats the price tag on that?

It's one of those, if you have to ask, you can't afford deals.

[jo3y]

yeah i figured as much, just was curious if it was worth all that cost. I mean JZ motors do those numbers too. hmmm just curious.

[milKt]

wow whats the price tag on that?

Just look at it.

[mazur]

Where's the inconel tubing? I'm confused.

[bdeitemeyer]

True, but sometimes it's not always about the numbers. The quality and engineering in that 4g63 is beyond comparison. If I had to guess on the cost of this build, I'd say somewhere between $150k-300k...without having any clue about the labor charges. Extreme Tuners does top-notch builds, so I wouldn't expect them to have competitive prices with your local tuner shops...you get what you pay for, and with those guys you're getting a masterpiece.

[biglou911]

this is some sikk stuff!!!!

[qscftz]

reminds me of the Norwood nitro motor, also a unique piece... unfortunatly

[rundatrack]

Serious engineering!

Fakk yeah...... wow

[yessir7]

any one else notice the kind of car the "hater" drives, lol

[nyskiffie]

we all just chose to ignore him. He could drive a Zonda R, if you're gonna hate on this car you're still an idiot.

[FastrTHNu]

a) *mocks*

ok simple jack
