I'll talk to Giles and see what he says. And I really don't want to spend 570$ on new pistons and another 600 on new 1.9 head. I'm going to upgrade rods so stop telling me not too. I've seen them bend and I don't want to have to deal with it. It cost me less to do it know then when I'm at a track 200 km away and have to drive home.

These rods are good for high hp and power. Bad for low end torque. I will have a lot of low end torque.

how are you going to achieve that? compounds? big VNT? Nitrous?

Compounds. K03 and a t3 with 50 trim and .48 ar. Water meth, water/air IC, cam, the whole 9 yards. im not skimping on anything

down the road i might do nitrous and propane injection but Ive heard your way more likely to blow your motor on propane. Also might go with a third bigger turbo down the road if i can figure out how to keep the head bolted down or convince my cnc friends at work to make me a steel head

What T3 specifically are you planning to use?
A regular, old school Garrett product will not get you in the 200-hp range reliably.
It is possible, but those engines tend not to run very long..
Maybe consider a well-flowing modern turbo instead?

Just my 2p...

You are skimping on the turbochargers! Put in something useful instead of those stoneage turbos ;)

It's a brand new airesearch turbo. The t3 isn't a t3 ether, It's bigger. Old t3 is about a 35 or 40 trim and not sure ar but lower than .48. Mine is a 50 trim with a .48. It's what people use to make 250 hp out of these motors. Problem is getting them to spool. That's why I have the k03 there. And it's rebuilt.

T3 50 trim producing 250hp on an IDI? BS!

27lbs/min (at best!) won't get you anywhere near 250hp...

Well we will find out how it's works when I'm done.

And prove me wrong. Don't just tell me.

on paper it is good for 250hp at the crank, in practice is another story, i think the possibility of breaking 200whp with it would be safe to assume for now tho, but 250 will take quite a bit more than 30psi.  But certainly the scandinavians of the forum know far more of what actually works and what doesn't.  I don't think i would put a ko3 from a tdi on any performance oriented engine.

you are gonna need a seriously big external wastegate to bypass that K03 at high RPM..

The pen and paper for my similar build was 250 crank hp, 34 lb/min at a 3.2 p/r. Boost was in the 30's. Not many turbos out there in that range. I don't know how it would work in a sequential setup(bypassing small one after spooling). Would the smaller turbo move the surge line to the left on the compressor map?

Garrett GTX2863 abd GTX3076, both are in the 73-74% range of the map as a single (on paper).

Maybe 27lbs/min would give you 250 real bhp on a petrol engine but less on a TDI and even less than that on an IDI. I'll give you a couple hints: BSFC, AFR and VE. Read up, compare the different engines and consider what you learn to be the proof that you are making WILD claims.

Lost me at compressor mapping...

The k03 is still up in the air. If I can find another turbo a little bigger then I will grab that instead. Like I have said before, this is my first true top to bottom build and I am expecting to go down a few wrong roads. If I have to changes things then I will. But as I am now I am basing things off of research I've done, what people have told me and sheer guessing.

if your still looking for rods look at Pauter. They got some good stuff. That is what I am running in my Franken Engine. I bent the stock rods. 3 out of 4 were bent. So far with these not a problem.
