Very sad day

Its only been around a month since my car was finished from its gtx2867r, putting out 400bhp at 26psi. Very happy with the power but things started to appear not quite right, a few odd oil leaks, the usual boost leak.

Then last week a massive oil explosion happened, high crankcase pressure. Oh no.

Engine stripped today and the worst has been confirmed.

Oil pump failure, crank has had it, piston rings, bearings etc all knackered, inlet cam, possibly exhaust cam not seen it yet. Bores scored etc

Somehow something has got in my turbo and destroyed the comp wheel and messed up the housing, literally no idea how that's happened.

Very bad day. So now I'm wondering what to do, looking for big turbo guys advice. Do I source a second hand engine and replace or take the opportunity to go stroker?

Would it be worthwhile to go stroker on gtx2867r or go GT30 stroker? Or just replace what I can?
Engine itself is standard other than rods.

Opinions welcome

was it high crankcase pressure that caused the oil explosion? what PCV setup were you running?

If you were happy with the drivability off boost I wouldn't worry about the stroker, but I am currently running a stroker and it drives a dream off boost

Depends on your budget...

Personally I'd spend the money building a solid engine then bolt what you have left to it... if you need to replace the turbo then I'd consider something other than the GTX2867

Oil pump failed, piston rings then failed, causing the high crankcase pressure and thus oil explosion and oil leaks everywhere. Engine bay was covered. As far as I'm aware you don't know an oil pump has failed until it's too late unless you have an oil pressure gauge. PCV system was standard, no catch can.

No problems off boost with gtx2867r. Not sure yet if the compressor housing damage can be machined out or not yet, just wondering whether stroker and gt30 might be a better option?

Well I'm running a stroker and gtx30 and although I'm not running high boost yet, it drives very well off boost. Plenty more torque at low revs than my 320i

No low pressure warning on dash? Or did it all happen in an instant?

Low pressure came up, pulled up to have a look and oil had exploded in the engine bay, dripping all down onto the floor.

I have very little luck with cars it seems:sorry:

Just can't decide which way to go next.

I should hopefully have some pictures by the end of the day.

Sorry to hear of your problems but a long standing rule has been that if you want a quick car then go buy one; modifying is great but has it's hazards as all components are rarely uprated and it take just one of them STD ones to exceed designed limitations and pop!

PS: loved my 8L S3 but then drove an RS3 and later that day it was goodbye S3 and hello RS3, it's just soooo much more... :superman:

Wheres the fun in that???

For what its worth I have an OE oil pump in my not so std engine... most people building an engine for this level of modification would have already uprated relevant components anyway so this argument is a little moot...

As for the "long standing rule"... with all due respect thats boll*x... there has been and alway will be modders and 'buyers'... I have been modding cars since I could drive and wouldn't have it any other way... there will always be people in both camps... if you want to buy a faster car then thats fine... if you want to mod your car then thats fine too... there are no rules either way..

Long standing rule? People were putting big V8's in passenger cars in the 1930's... What long standing rule is this you speak of?

If people didn't modify cars, you know high performance factory cars wouldn't exist, right? You're welcome.

I agree, I agree, just saying what happens and it's happened to me with the 8L S3; uprated the engine and the clutch starts slipping, etc...

That's why you upgrade EVERYTHING!!!!! :D

Sad news, OP. I'd stroke it. Seize the day.

@45bvtc did Audi ever issue a recall on the RS3 for the prop shaft failures?

Not to my knowledge Alex; a few were replaced like-for-like but then Audi concluded that in general the cars that suffered failure had either, a) been re-mapped, or b) had been launched excessively

A typical failure:

And the last time, in 1968, I was involved professionally in putting a V8 into a 'small' car was the Westfield Seight, and GREAT fun that was, too; I later did the technical manuals and owners instructions - as shown:

So I do know well of what you mean... :readit:
