I was wondering when you all think there will be some form of product, or results in regards to how these cars are going to take to modification. AMS, BR, Norris Design...

I do remember reading up and one of them saying that these cars having an aluminum block will now require major internal modification even only after 100-200whp gain. Leaving these things at roughly 400ish whp, and that even pushing it...

Iron block may be heavier, but I'd much rather have 600whp potential (and have that extra 27lbs vs the Alum.) than have to reach deeper into my pockets.

 

There are tons of other cars with aluminum blocks making great power. People have been doing it with Honda motors for the last 10+ years. Stop jumping to conclusions about the potential of the alum block, and wait.

 

Sure they have, but not neccessarily without internal modification... You can slap a GT42R on a 1.6L B series... huge FMIC and bla bla but without pistons, rods, crank, cams, bla bla bla...

 

I would like to know of an engine w/ aluminum block and big turbo without being sleeved and decked.

An sr20 is an aluminum block motor.
an LS1 is a aluminum block motor.
please, if there is one thing that holds this motor from over 600hp it is not going to be the aluminum block.
stop being ignorant

 

s2000... stock block record 630~whp totally open deck, stock cams, just 3mm headgasket. People really need to stop crying over the aluminum block. The 4b11t evo block is semi closed with sleeves in it already.

 

i love the 4g63, not the new 4b11 whatever. Only time will tell how tuneable and good the new engine is, i hope its good

 

The good thing about the 4B11t is that is comes sleeved from the factory.

 

So what sti blocks come sleved from the factory and are a semi closed deck block and can still blow up with a large turbo. Dosent mean the evo x wont. Don't get your hopes up untill you see results.

 

Sti motors tend to crack piston ring lands, they generally don't have sleeve problems until well in excess of 600 hp or more.

I have high hopes about the new motor. It will be a beast.

 

Sure they dont generally have cracked sleeve problems but like i said once your using a large turbo its a different story and most people arent using large turbos on stis like 40r plus turbos for those exact reasons i stated. Well see what the real deal is with evo x's when tuners start slapping on 40r plus turbos on them.

 

I think they will be fine. My stock motor has 507WHP on race gas for over 2 years now with no issues. The stock block record for an STi is 634WHP (ran 10.3 @ 137) so I wouldn't get to worried about the 4B11T, it won't be a 4G63 as far as the block for 1000WHP but it would be enough for most enthusiast. Now the weight is a different subject.

 

Coming from about ten years of honda' all motor supercharger and turbo, you can do anything to the motor stock. The real question on honda's is, will the stock block be reliable with alot of hp. 400 whp on honda's will work if you got pistons and rod's, not saying that stock pistons won't work just that ring lands will go bye bye. Even if you swap out for pistons and rods, your weak link is now the sleeve's. I've been through that and I'd like somthing that will last.

 

People with honda's like myself build the motors with sleeve'd blocks to handle the power. Thats the right way of doing it. And don't torque the headbolts to tight, those threads do come out Ever heard of helicoil?

 

I'll go out on a limb here and say that nobody will find out how much power the short block will be able to handle until the ECU setup is cracked. New gen ECU's are much tougher to hack; the 4G63 had it easy with it's practically open-source ECU. Time will tell of course; we can hope the new ECU will be easy. Ripping it out and going full standalone may have more repercussions than most people want to deal with [like no RKE, immobilizer, dashboard displays being all driven by CAN].
