Probably spooled quick and then run outta puff at the top end,ย  as I think most 2.5 ltr turbos have a 8cm hotside and 2ltr has a 7cm .

Just check with fastline that you have the right sized oil feed banjo bolts,ย  if they didn't supply them with the turbo ๐Ÿ˜‰

Just taken a quick spin to make sure all works - had big issues with the oil drain pipe and clip :wallbash: then had the obligatory air lock in the heater matrix. The 4th cylinder mod didnt seem to help with that. In the end I unplugged the hose at the bulkhead and topped it up from there.

Kept it off boost but I believe you are correct I could feel the spool starting but it did not seem as urgent so I think as you have said there will a smoother delivery for longer. Need to chase up a mapper to make sure all is well.ย  But the smell of burnt oil is now goneย :biggrin:

Looks nice , coated hotside as well by the looks of it ๐Ÿ˜Ž

The vf34 ,is a bug /blob 2ltr jdm sti turbo afaik , is yours a 2.5 ?

Yes mine is 2.5l

turbo installed - the oil return to the sump is the most frustrating thing, 4 hours fighting with it then just managed to get the position of the pliers, my hand and the angle of the spring clip just right and it went into place.

Booked in with TDRacing Warwick to get the fuelling checked

Modified the heat guard around the headers to up pipe as the sensor is well and truly in place so this meant I could remove it without damaging the sensor

Visited TDR in Warwick to check the fueling after replacing the VF34 for the standard VF48.

Nice safe results s# mode 348BHP (288 WHP) tickover was raised from 620 to 740, has smoothed out the idle nicely not quite as loud on the startup

Fitted some gauges

Extending the power supply in the same way

I connected the power supply to the appropriate feeds used for the Stereo and routed the sensor leads from under the dash up behind the console, then fitted the new surround from South Coast Flocking

Fitted a resonated mid section, had to cut about 50mm - think they may have sent me one for the saloon? Quick session with the angle grinder and cutting disc sorted that out. Using a phone app, I recorded a 3dB drop (94dB to 91dB) which is enough to keep the identity but now (so far) does not make my ears ring on a prolonged spirited driving session

Not by trade - started to keep maintenance costs down years ago and was always tinkering plus fixing the odd thing by the roadside ๐Ÿ˜
