its actually torque that requires a new clutch. and a k04 actually puts more stress on the clutch (and rods) than some BT's. but since you got your new clutch you dont have to worry about it.

you can find the sp51 wheel on ebay, i think docurley was planning on running it last i heard. but if your planning on pushing the k04 past 250hp your gona want supporting mods like an exhaust manifold and fmic, which is the same as a gtrs. you can always run the gtrs at a lower boost without those supporting mods anyway. so really the only difference in price between the 2 setups is the cost of the turbo, which is minuscule. yet the gtrs has the potential to produce way more power and doesn't choke out in the higher rpm's

 

If anyone cares, I have the "regular" gpop k04 upgrade, and it has made a HUGE difference and I'm still on my dahlback k03 chip. On a budget I would deffinetly do it again. Also I got it back when it was still priced at $495.

 

yeah, i wish it was still that price...

 

not exactly. i have to pay $890 for the unitronic file as well. and you need bigger injectors, fmic, 3" intake, a few little things.

the cost difference is way more then you realize.

 

But you would need bigger injectors, fmic, 3"maf housing, and a bunch of other things to get 250hp out of the 250hp rated turbo. If you are going with the basic k04 file, there is really no reason to pay for the upgraded turbo, which is what your question is all about.... Right?

 

^what he said. you cant push the k04 to the max without those mods anyways. so 300 difference in tuning and the difference between the cost of the turbo. thats it

 

a guy chipped with the sp51x and no other mods has 243bhp. i think this turbo without to many mods is a big increase from the k03s and you can slowly upgrade those other mods without worrying. since the gpop turbo is pretty much the exact same, im expecting simular results.

 

Yes, but you have an AEB with a K03. We're talking about an AWM with a K03S here. A K03S is very close to a K04 and only has a difference of about 10hp.

Where did he get that number? Bhp and awhp are two totally different things. 243 bhp translates to what, 200-210 awhp? Bhp is "brake horsepower," in other words, output at the crank of an engine on a loaded (braked) dyno. Is it an upgrade? Sure, and it will be a blast, but don't expect it to be a rocket ship.

Additionally, in order to take full advantage of any turbo larger than a K03S, you really need a FMIC to keep down IATs. The expensive cost of a FMIC and S4 front bumper to fit over a decent sized one are what have kept me from going bigger than my stock turbo at this time. >

Whatever you decide to do, good luck!

 

good thing i already have a s4 bumper. and i know the difference between bhp and whp, i didn't want to mislead u by saying it was whp.

i totally understand what u guys are saying, i guess i wanted to know if there was any flaws, bad exp. or better setups without going bt. but i realize thats not a whole lot of choices.

and heres the link of the guys dyno with the sp51x, its pretty cool and he hasn't had much done at all.

That my mate who runs the Hybrid turbo and I have mine going on today but it is in fact the Scroll sp51 Outlaw version with a twin oil feed CHAR so it's somewhat better spec then the G upgrade plus they use there own design turbine blades.

The only mod the Outlaw is running on my mates car is an exhaust the rest is all stock bar a custom remap. I on the other hand will be looking to run a setup like some of your hammer files: 380 injectors, FMIC, SB Stage III clutch, 3" S3 MAF and 2.75" exhaust. We already have a 4bar FPR so I don’t think I will need to swap that out and will be looking to hit the 260-270bhp figure and you guys struggle to make 250bhp with the same setup so the fact the Scroll turbo can do this with just a remap says it all.

My turbo was a dead K04 bought from Canada for $200 (I was feel generous) and I paid $650 for the Outlaw conversion which bring the turbo to a higher spec turbo that the K04-23 (TT225 turbo) so I have an Hybrid turbo for the cost of a stock K04-15 plus current K04-15 units are going for nearly $1000 so this make this a very viable option.

The other option you could do is get your K03s turbo’s and get it converted to K04-15 spec which I think is around $550 if a K04 is all you want.
