dokładnie tak jest. zresztą tragedia nie miała nic do czynienia z mocą, ale to właściciel później opisze..

no właśnie - tylko gwarancję czego? głupiego pomysłu?

Zobaczymy co z tego będzie bo właściciel nie rezygnuje i tym razem już zakuje cały silnik :wink:

Hi, i hope it's no problem that i write in english, any translation tool would end in chaos

The engine didn't blew in consequence of the power, it was still far away from that point. The problem was a faulty spark plug, the plug overheatet and the electrode began to glow wich caused pre-ignition. When this happens the fuel ignites already when the piston is on his way up, this will either cause the piston to melt and brake or the connecting rod will brake.

I still don't exactly know why the spark plug failed, maybe a mechanic overtightend it after the last compression test wich can cause a spark plug to get damaged.

The rest of the engine looks fine for several years track racing and over 20.000km with turbo.

kto by pomyślał :eek:

Świeca takie spustoszenie zrobiła...

Seryjna kompresja, świece o za wysokiej ciepłocie i jak widać wystarczyło, ale mogę sie mylić oczywiście

Czyli, ten silnik wytrzymał by tą moc gdyby była lepsza świeca :?:

Update:

New block, a mildly ported head and forged internals

And just before the engine blew i finished a new brake system, Porsche 996 Turbo Calipers and ST205 brake discs (315x32mm), barely fits the 16" wheels :wink:

Very nice

Hi Hafkai
good job :-D

but what with the sparks now ? will you use the another one ?
and the pistons are they OEM ?
have you got a lot of problems with install set of Porsche 996 Turbo Calipers and ST205 brake discs ? Are the rear breaks the same compilation of set ?
good luck with fast run :-D

Hafkai · Postautor: **Hafkai** » 27-12-10, 01:01

Hey Rzeski

I will use them same spark plugs at first, but i will buy another set of colder spark plugs for higher boost and racetrack.
The Pistons are from Wiseco, 0.5mm overbore.

The Porsche brake was actually pretty easy to install, a local tuning shop build me some adapters to mount them, the ST205 brake discs fit almost perfect, i just had to grind 1mm from the lower ball joint so they dont scrape unter load.
The rear brake is still the original ST brake, no problem with the ABS or something else.

did You think about 4age head? In Your situation it is pretty easy to install and run

I thought about using a GE head but i will try to get as far as possible with the FE head, they got some advantages, the only thing that is restricting is the absence of any aftermarket camshafts so it's hard to get the engine to rev higher than 6500 and make power.
The only way is to let the stock camshafts regrind but i'm no fan of that.

Hi, the new engine is almost ready, it took much longer than i expected but i hope the car will run at the end of the month :-)

Awesome!

what was changed ? only rebuild ? what`s with compression ratio ?
i wish realy good 1 start :-D

Hafkai · Postautor: **Hafkai** » 19-07-11, 12:53

The compression ratio was changed with the new Wiseco pistons to 9:1 instead of 9,5:1.
The connecting rods are typical h-beam rods, the rest of the engine was reabuild with Toyota parts. The turbo is now a T28 from a Nissan 200SX S14, quite a bit larger than the old T25.

I removed the stock ECU and the e-Manage Ultimate and installed a EMS 6860 standalone, this will make the first start a bit tricky
