The Project Pad

You can add me to the list of 30r's running strong on a stock block (even though mine was a Holset). Same power capabilities. Soon I'll be on the 42r (equivalent) on stock block list lol... probably not for long.

For some reason I get a lot heat for believing on the internal strengths on an AAN... it's obvious all things have a limit but to disqualify every other variable that could go wrong and simply say "above RS2 levels can bend rods so 30R is a definate no-no" with no evidence just doesn't settle well with me...

But hey I'll be putting a 58mm PTE soon and strongers rods I'll do as a precaution as I'll be going more for low end response and torque (.63 AR) & I know that type of tune could decrease the lifespan of stock internals in the long run...

Same type of comments about 7ats. Same rods just less tolerant pistons.

You sure know how to twist words around OB. Couldn't let it die, had to bring it to another forum eh?

Saying that there is "no evidence" of 20vt rods bending due to high cylinder pressures is naive and foolish, to quote my earlier post. You either haven't been around long enough or haven't been paying attention because plenty of people have done it.

I absolutely recognize that the AAN is a *very* strong short block from the factory. One of the best. But if you have any concern for the longevity of the motor you need to choose turbos wisely. Strapping 30R's to fatigued 200k+ factory short blocks and assuming that you're good-to-go is just dumb.

As I said before, running a 30r (or equivalent-sized turbo) at lower boost levels is fine. Not gonna blow anything up. That is what both Nick and Chris are/were doing. And since they both have plans to build the bottom end it made sense for them to buy those turbos. If someone plans to keep the stock bottom end then a 30r is NOT a good choice as they could be making the same power with less lag had they chosen a better alternative. If you're not running a turbo at it's maximum efficiency, then you're running the wrong turbo. I know you don't care about efficiency or compressor maps though. Do you really need to physically SEE someone blow up a motor to believe it happens?

The ad that was posted claimed 480hp. My point was that is a bad idea if you have concern for keeping the motor running for any extended period of time, "walking on thin ice" as they say. MAYBE it will run great for 20k miles, MAYBE it will blow up after 2k miles...that is the entire point. Wasn't trying to give you shit about it, but a false sense of confidence never ends well. That car isn't making 480hp anyways.

I won't thread-jack Nick's project thread anymore, so here is the convo that got dragged over here: http://forums.quattroworld.com/s4s6/msgs/140688.phtml

All I did was post pictures & commented on the turbo that was running fine on it, efficiency wasn't mentioned nor compressor maps ect... I sort of wanted it to be an inside type joke without it being a TJ... but then you linked the post...

who's really taking this to heart here... relax Ed,... Rest assured, I'm building my block & understand why I'm doing so...

Thanks cuz I know I'm not alone here... we all have our own experiences that shape and mold our beliefs. I've learned from others mistake and my own & proceed according with caution, of course. But I'm in no way a purist & more an enthusiast like most that have agreed with my way of thinking... If it weren't for the enthusiast we would have data on how unorthodox methods work & respond to traditional method...

With that being said I'd wanna see how far an AAN block would go on loxx's 42R...

Its really a 67/99mm HX52 which will flow 90 lb/lm according to some (lowest I've seen is 87 lb/min) which is right in the same neck of the woods as a 42r. I probably wont be able to push it much on stock block due to my clutch, but I'll try lol. The plan is to get it on (waiting on some 4" SS piping blah) and then run it on stock block/trans until I can get some time and space to tear it down and do a full engine build/trans build. I am willing to be 15psi will be fine on it at least.

I may have a new turbo setup come spring...we'll see. My buddy decided he's getting out of the car thing for a bit and is parting out his 730whp Honda Civic and I offered to pick up his HTA86 GT35r. That'd work quite nice with a new manifold and a built bottom end I'd say.

Hank's manifolds are nice

You talking exhaust manifold?

yes, mine is almost done

Let's see some teaser pics
