As the titel tells I´m going to upgrade my K03-005 turbo to either a K03-SP51R witch should be able to produce 220hp or K04-SP51X 250+hp.

If I upgrade to the K03-Sp51R I will recieve the the turbo internals and will be able to change these myself. Price: 615$.

If I upgrade to the K04-SP51X I will have to send my turbo away to be reworked to fit the larger internals. Price:965$

I will get my car custom mapped in both cases.

At the moment I'm leaning towards the K04 option the other one seams to be a waste of money. Now to the questions:
-When will I have to change the MAF and to what?
-When will I have to change injectors/FPR?
-Anything else that should be changed?

Mod at the moment:
-2.5" cat-back
-tuningchip
-openfilter

 

which motor are we talking about?...is it an AEB?

Im guessing that it is an aeb...you can run a PC-16 file from GIAC...

you will need

FPR
injectors
intercooler
chip (mentioned above)
you already have exhaust

definitely go ko4....

well, gl!

 

Yep AEB motor.
As I live in Finland I don't think the GIAC chips will work so i think a custom re-map is the only way to go =(
I kind of figured that I will need these things but I wanted to know how much HP the stock parts can produce.
What FPR/injectors should be used?
Will the stock cat flow good enough?

 

this should give you an idea

Docurly....a guy on here just got the SP51X...he may be able to give you a little more insight....

gl!

 

Well I have the SP51x Outlaw version on the K05-15 turbo which got fitted Monday and on my K03s chip is mad. This thing boost to 24+ psi without any issues (still trying to tame it with my EBC).

I'm shocked at the price hike as I only paid $650 + shipping $725 but hay thing are crazy right now.

I will be running all of the above but will be going with a custom map and SB Stage III. I'm hopping to have the final setup running by the first week of next month as I have a track day challenge with my friend running my turbo with just an exhaust, clutch and a custom map on his FWD A4 with 243bhp.

 

Wow that sounds great =)
I think the price differance is because they will be re-machining my K03 to K04 specs. The basic upgrade is the K03-SP51R option which is 550$.
What kind of mod are you running with the outlaw? And what kind of hp numbers are you expecting when you get it re-mapped?
I'm thinking of getting:
-FPR & Injector (don't know what to get yet)
-FMIC (maybe)
-HF-cat or 2.5" DP with HF-cat (maybe)
-Remap

 

I sent him a dead K04-15 which had to have the same work as yours but with a K04-23 shaft and larger turbine put in so it still gone up quite a bit but then I was one of the first to have this done.

I will be running 380 Semen’s injectors, 2.75" exhaust, 3" S3/225TT MAF, Racetec FMIC, Profec B II EBC and SB III Clutch. I'm expecting around 260-270bhp mark once mapped.

 

theres a place here in ny where i can bring my car in and get a k04 and giac with pc-16 file for 2000$ comes with everything FPR injectors intercooler....

 

I don't think I'll be shipping my car 4000 miles to NY and back to get it tuned... =)
When will a bigger MAF be necessary? Can I make 250hp with the stock one?

 

Does that include FMIC & clutch?

My total cost so far:
