Default extensive comunication w/ TJM, hopefully a K04-23 soon........

I was looking at MJMturbos.com and saw the K04-23 (bigger than K04-15 but still direct bolt on) so i called up TJM to see if they can do tuning for it, they got back to em today and said yes. they couldnt tell em expected horsepower but it should be between their regular K04-15 setup (240 hp @ 5350 r/min and 284 lb-ft @ 3400 r/min) and the next step up wich uses a custom turbo built for dahlback by KKK (286 hp @ 5500 r/min and 304 lb-ft @ 3450 r/min) the turbo costs 995$ the bosch injectors cost 800$ and ill ahve to pay the chip re-burn one time fee of 300$ (i got the dahlback chip for 500$ because i didnt pay that fee in the first place) so for 2100$ it seems liek a pretty good option. or do you think id be better off with a more havily tuned K04-15? oh and if (when) i add a front mount i get the chip re-burnt for free, or if the program is off (by looking at dyno charts, EGTs or other readings that ill do once installed) all future re-burns will be free.
any opinions or feedback is greatly apreciated.

Default Just dont expect to push the boost up too much over 15psi.

Not the first time someone has tried using that turbo.

For the cost, why not the T28 PES set-up or something similar. I rode in a B5 with the PES kit... Yikes awesome.

Put down about 230 on a dyno dynamics machine nice and smooth, very similar torque and whp of a stock Subaru STI..

Just a thought..

Default I say listen to Tim @TJM, they arent known to make false claims

And besides the tuning has more to do with it all than the turbo. Turbo just sets the outer boundry, if you cant tune you will never get there.
