Td04 to td05 16 g
Discussion
Hi I have a 1997 wrx wagon with td04 turbo ,car is going in for a remap via esl soon with full decat, panel filter, walbro pump 3 port boost solenoid ,I was thinking of putting a Td05 16 turbo on and 440 injectors , would it be worth it for the power gain . I have seen some td04 running 300 bhp , what do you reckon thanks
No reflection on your tuner or anything else like that but 318bhp from a 16G and those injectors which are clearly more man enough for the job is pretty poor. I assume you run a front mount intercooler and some kind of induction kit with a walbro fuel pump and full decat exhaust system.
I can only think there must be some kind of issue with either your turbo, boost leaks, Vacuum leak, EBCS dirty or faulty, uppipe leak, too much DET maybe due to using 95RON instead of 99RON or just a bad batch of fuel, it happens, or too much boost or timing or even very low compression on your engine, faulty sensor, faulty fuel pump etc...
That doesn't sound right at all as the 16G will definitely make 330-340+, specially if there is plenty of fuel on tap, or perhaps the tuner tuned it to that level as he felt it might have been the safest state of tune for the condition of the engine or as i've said, maybe it was getting a lot of DET.
You might need to go back to him to have another look at it.

Update on this , I was let down on the turbo so had the car mapped with the td04 , sti panel filter ,walbro pump , full decat and 3 port boost solenoid, using esl , was fun for a few weeks with the new improved boost over standard but as always I'm now bored of the power it has . what next my car is a 1997 wrx wagon low miles , thinking vf35 injectors and a sti8 top mount , or maybe a vf28 what do you think looking for around 330 bhp with quick spool thanks
