Can you do a swirl flap delete on the CAPA engine?
All it takes is money!We all wish we could get our hands on one of these cars!
Hi,
I know this thread is old but I need some advice from Turbo veterans.
I have modified myself my 330d E90 2007 prelci to a 354hp 787nm... my set up is:
- Full 76mm exhaust no silencers dual exit
- EGR, DPF, SWIRL FLAPS removed and deleted from system.
- hpfp modified and 2015 model #pn
- 2015 injectors
- uprated IC w/ 2.5" piping
- Custom Map
- Hybrid GTB2260VKLR double ceramic bearings w/ modified manifold
Now, my can is running out of air apparently. I am running at 2.7 bars (real) and I cannot extract any more HP from that turbo.
Already tested my with similar settings made for a 535d running 420hp but only smokes and power is 355hp... so no improvement.
Turbine is standard 44.5 / 50.x mm
Compressor is billed 69mm / 71 exdended 73mm tip.
I need a bigger turbine but as far I can see is impossible to fit a bigger turbine because new VNT mechanism, is that correct? Anybody knows if is possible to fit a bigger turbine to VKLR?
I have another turbo to go soon and replace the VKLR but I would like to know my possibilities before I modify everything again.
Thanks,
Jackson.
Do I have to machine the turbine casing and get it all balanced again? Is it really compatible with vklr core and vnt system? I read that it would touch vanes when fully open.You can fit there the slightly larger AMG turbine, but it wont take you alot further also. Around 380-400hp maybe.
Edit: How does your vklr spool by the way, with that big CW?
Hi,What not try two gtd1752vrk or one GTC3576V?
just a thouht
Hi,
I will have to do a lot of modifications to install 2 parallel turbos..already thought that, ever triple turbo from 550d but nice idea.
Is the gtc3576 ball bearing and vnt? Have you got wheels sizes?
What about the BG S300V.. ?? I purchased it from america and I will probably replace my current kit with it.
Thanks,
Jackson

Hi,What S300V version? With 56mm inducer comp wheel or maybe 60mm inducer?
I wonder if you had any issues with the vklr turbo yet, what EGT do you see for that boost ? Reason i ask is one of my mates had no end of issues with the vklr turbo, the retaining bolts keep coming off loose and the vnt has been damaged in a few ocasions. The locating pins are also coming off/braking and the vnt ring keep spinning inside the turbo throwing actuator alignment off ! He drilled the bolts to take larger bolts and so far it holds however i like the gtb2260vk better as the vnt ring is secured with bolts and never had one behaving like that yet !Hi,
Spool is very good. What do you mean fit a amg 49mm turbine? The grb2260vklr wont accept that turbine, already spoke to the company who modified my turbo.
Do you know somebody who upgrade a turbine of a gtb2260vklr? Please send me details if possible.
Regards,
Jackson.
Did they say the reason also? I heard same thing when i wanted bigger turbines to my gtb1749vk-s. Eventually made them bymyself. AMG turbine fits to gtb2260vk without any issues. Havent taken a vklr appart jet but i wouldnt be suprised if the shaft is same as 2260vk.Hi,

Not the same, there are major differences in the shaft where it fits onto the ball bearing cartridge...Did they say the reason also?

Where did you get this info from? I've been running over 300hp for a while now with the BITDI intercooler and the DPF in place.3. Real 302HP with DPF is not good. Exhaust temperature maybe too high. If he turned off temp related limiter in tune it might damage car. Remap definitely useful. New Turbo can give more air pressure (boost) to make more power.
