hi everyone,i have a 99 uk turbo wagon,i put a ninja sports cat on,magnex mid section and h&s backbox with an sti/p1 top mount,i went and had an ecutek remap and only produced 238/281,i was happy with the tourque output but dissapointed in the bhp,i later come to find that during the time it was mapped i had a faulty knock sensor,and the plugs were due,since this i replaced the plugs with denso ik22 iridiums,new knock sensor and new maf,would this have affected the bhp output?anyway in the next 2-4 weeks its going back in to have a walbro pump,vf35 turbo,lightweight flywheel and new clutch fitted,and then a map tweek,(im keeping the standard 440 injectors and not going front mount),what sort of figures should i be expecting roughly? thanks in advance!

it's the torque that matters mate

im hoping for 300/300,does this seem reachable?i was dissapointed as most 99 cars reach around 260bhp on td04,im hoping that it was due to knock sensor etc. anyone?

300 sounds right you may max at 320bhp on your 440's unless you go 3.5 bar on your fuel reg. Also look into a 3 port worth it for £85, just to controll boost.

spoke to my mapper about that and he said not to worry bout a 3 port,im not bothered about much over 300 just as long as i get close to it with the same in torque,do u think that the 238 bhp i got before was down to the knock sensor etc?just seems like 60 odd bhp to gain from the vf35 is asking a bit too much?

Not at all - you should have seen 270/280 though with your TD04?

Mine makes 273bhp/273lbft on the TD04.

perhaps my td04 is very tired? car has had a new bottom end and is in overall very good condition,i believe that wagons tend to make a bit less power? my engine is in great shape,what should i expect?will the vf35 gain me approx 60 bhp?

StiX

Yes. I have just bought a VF35 and am hoping for 320 after a tweak to my remap.

hummmm,that means if i gain 50 bhp ill still only be looking at 288bhp with vf35,would the car have been down on power due to the knock,maf and plugs,and a possibly tired td04? if so im hoping that because i have replaced them all i should be 300-320bhp,with the vf35 etc,am i dreaming or is it likely that the knock,maf and plugs wouldnt have made much difference in the power output?

I went from a mapped TD04 to a VF35 (only other change was 550cc inj and ported oe headers) TD04 topped out at 270 the VF35 333, both on PS rollers. So yes you can make 60odd, with the right mods..!

Something to think about, you WILL notice after having the VF35 fitted/mapped the response will feel ****e. Even though the 35 is a very fast spooling turbo it's no match for the titchy TD04. You will therefore feel like you need to press the accelerator a lot more for any give amount of acceleration. You will soon get used to it and then appreciate the much better mid to top end grunt the 35 provides.

Don't forget the VF35 needs some waste gate porting to prevent boost creep/surge..!

One other thing, have you considered a TD04 hybrid..?

already got the vf35 and was lead to believe it is a quickish spooling turbo,im hoping it performs similar to the td04,i just wanted more power than my obviously crap td04 is producing(238bhp),couldnt really understand it,just hoping that the vf35 and the new bits etc is really gonna make up for it,im hoping for around 300 but would be a little dissapointed if it only reached around 280bhp,what u think?

With your mods/existing hardware, etc, then it's the TMIC that is prob the limiting factor but you still should get 300-310bhp, possibly 320 (the 440's are prob good for 330 and the turbo should do 330-340).

One thing I would change are your spark plugs LOL. I'd replace them with non-Iridium NGK PFR7B, personally...

thanks for that joz,my fingers are crossed and im only after 300/300! really hope i get it but i have my doubts due to the last mapping session but like i say i cant help but put that down to a tired td04,slightly dodgy maf,PLUGS,and a faulty knock sensor.would i be correct in thinking this?

Well, something must have been up to get only 230-odd bhp. As stated, you should have got about 270-280bhp. Do you reckon your sportscat is strangling power a bit? Is it a 100-cell one, or the more restrictive 200-cell type?

But your hypothesis about the turbo is a good one I think. If it was tired then it prob wouldn't be very keen as it approached the redline, hence the low bhp - but could still make the peak torque at about 5k or less, hence your 'normal' obtained lb ft figure...

Can't be the cat - as his is the same as mine and I have had no probs with it.

Does sound like the turbo.

99greenwagon

iTrader: (39)

yeah my mapper said it was the most he could get from it(td04) and the sports cat is a ninja 100 cell(£300 one),cant be that!

300 here we come then!

StiX

Yes me too - can't wait to get new parts fitted and remapped

When I had my first remap the drive home compared to drive there was much better!! Not just because of 43 more horses top end - there was a lot more bhp & torque right across the rev range.

99greenwagon

iTrader: (39)

yeah same here,i gained 70 lbft last time,and 35 bhp,will the vf35 give me any more torque?

StiX

iTrader: (4)

Should do yes.
