Thats all out dated information, If 2 reputable (enough) company's are pushing a kit, backing a 100% increase in power then what is your argument?

Zpi is running a 14b btw.

You need to start collecting facts, not assumptions and opinions.

 

i AM collecting facts and outdated or not, the kits they talk about in that and many other posts are the same ones that are out now. i never started an argument what so ever about any turbo kit company what so ever, i simply started researching for upgrade parts for the more indepth tuners that would be VERY useful. if you have a problem with the products that i find that WILL help in anycase, then stop comming back to this post. i'm going by other people's experiences with these kits and what more they could see out of them with the right parts. i'm taking in incident reports about what problems go wrong and going out and finding upgrades to prevent that from happening IE heavier duty axles, stronger rods and crank, stronger pistons and better engine heads and so forth. i always read up on here about those who want more power, well i'm finding ways of bringing that to reality. if the part doesn't exsist, then i'll find out where to get a custom piece and for how much and i'll still post it for info for other members of the boards who may find it useful to them.

the turbo kit companies can indeed back thier 100% increase, thats fine and dandy and ya it shows, but theres parts on the xB that they are REALLY stressing for example the axle problem, new axles = never worry about it. i've hear of blown rods when pushing it, new rods = never worry about it. if someone isn't willing to go as far as to get even custom pieces made to protect the saftey of the settup and save them selfs lots of $$$ in replacing blown parts, the they shouldn't have gone and pushed it. want to be the faster on the block? then do whats neccessary to get there, thats what this thread is for, not putting down reputable turbo kit companies.

now for one more time, a basic summery. i started this thread to post findings of upgrade engine internals, drivetrain and power transfering components. don't appreciate the finds and help? fair enough, find your own alternatives. i'm out to make the best of my box, are you?

 

I love all the effort your doing to give us this information, its been DAM helpful for me. I will be most likely purchasing these pieces in the near future i want to push 12 PSI on my xA, but until i dont replace the internals i can only push 7PSI. The more information you can find me the better.

Dont pay attention to metal112524, who cares if its outdates, your looking for internala dn way on how to make our black stronger, i dont care about turbo kits, im looking for internals, as the topic states.

Seriously, the more information you can find the better, would be saving me alot of time and i dont have the patience, so please continue your search.

 

no joke! as for right now i'm in between jobs so i lituraly have all the time in the world right now to do the research and i'm glad it's helping!

i just got an email back about the crankshaft i posted a link to. it's just a stock replacement...

still waiting to hear from World One.

 

From what ive read and seen, isnt our crankshaft already forged?? You could balance it and do a couple of other things to it, but with the package from IPP and a set of rods you should be good to go.

With a GT2554R you could easily push 16lbs reliably into the block without getting out of the efficency range of the turbo. This is of course with low compression and forged internals.

As for driveshafts i dont think you need them, unless of course your drag racing. Im sure the OEM shafts can withstand 200WHP without a problem as long as you dont slam on the clutch. For regular circuit racing, where you get on the power gradually, you wont snap an axle.

 

guys not to rain on your parade or anything, but this is all old information thats been floating around for a while...I boosted my xB almost 3 years ago and found majority of these parts...I found a complete stoker kit for the xB...as far as the crank goes, your probly better off just knife edging the crank and for cams just get crower to do some regrinds for you. My friend over in Cali already has majority of these parts that he is gonna be using for his blitz supercharger build up....hes got everything including the axles, and is just waiting for AEM to realease its PNP standalone
heres the thread if you wants some more info

i'd personaly like to change the compression only down to 10.0:1 but i'm also having trouble seeing the benifit of lowering the compression.

you lower the compression of the piston and based on the engine it's self, it looses power, but we do it to have more turbo boost... if so, whats the point of doing it in the first place? if you lower the compression, you loose power off the barebone, but you're capable of boosting even more. to me it seems it would give the same power gains either way...

correct me if i'm wrong on that but the world is a trade off of equivelance.

for example, lower the compression and loose 20hp from the engine it's self to only gain that 20hp back from the extra amount of boost but still you wont be gaining more because you still have those physical limiting bounderies of the block and parts them selfs...

please clear me on this because i just don't get the point of changing the compression in the first place. does it allow for enough extra amounts of boost to actualy go from sa you're hitting... 170whp with stock compression and lets say you change that, wont it till be 170whp only with more boost to get there or will it actualy gain even more?

 

Wow nice, i totaly over looked that!

 

Lower compression lets you run more boost. Having said that, I've boosted cars at 8.5:1 up to 10.5:1.

Don't think so much about it.

 

i understand that, but my whole point is though... wouldn't you just see the same amount of power gain from that? if the compression from the amount of boost is back to 10.5:1 again, wouldn't it be the same?

 

Simplyscion covered my argument. You didnt find anything it was already found. People here know whats out for the xb, but the problem is there arent many that are going to go that far. My argument was that your bringing back a chase to the most whp when it already happend 3 years ago like simply said. Not to mention rollhard has his box up past 300whp getting close to 400. If you want REAL info go ask him on his forums, ask whats braking or broken.

And if your just looking to post up old info collectively for people too lazy to search the f/i thread, go ahead.

 

nope, it doesn't work that way.

google compression ratio and engines.

 

looks like most of that stuff is remanufactured stock replacements. your best bet is to take your motor to a local engine shop and have them do all the work. i wouldnt trust some "sales" guy on the phone telling me that it will handle 20psi. when it blows up, there are not going to give a crap. just an easier way to avoid headaches down the road

 

actualy that engine kit is actualy proven, but new rods are must and i saw on the other thread related to this one a link to the good rods.

as for that site mentioned above, yes it's all reman stock pieces, i hadn't gotten to posting that yet but i was told by the site sales reps that infact they are stock reman stuff.

 

new rods that were shown in the other relating thread can be found here: http://www.raceeng.com/pc-8538-46-cr...1nzfe-set.aspx

they are about twice as thick as the stock rods, stocks lituraly look like toothpicks compared to these.
