had speedvision 265 cams like i was running i cudent belive the power gain them speedvision cams gain if set right i used standard pulley but wasent on 4e markings i played with it as i found on the 4e markings on my 5e the cyclinders only got 100 psi so was out mind you i didnt no this i always thought it was a little dead when first driving it then i got it mapped with 100 psi when i found this out i reset timming got 165 psi god was a monster spinning it 4th with out lsd and 17ths so i do like this vf35 of mine

you said much head work i just said speedvisons cams, id love to see a standard gt just cruise along then plant it and see wheel spinning in 4th with out dumping the clutch, might have little 14 inch rollerblade wheels but still like to see a standard gt do that lol

a vf22 is larger than a vf34 and vf35.
most scooby owners who want to keep the low end grunt of the td04, with improved torque and power till the redline, or almost redline, fit the vf34/35 and recently vf43,
few of them fit the rest of the series due to them being old inefficient designs.
the td05 is a bit to laggy for what i want, (saying that i think sometimes my current td04 is a bit to laggy at times, but i pretty certain thats to do with the tune) the td04 just dont seem to provide much kick.
i have a heavily ported head as far as head work goes, and the stock cams are ideal for me cos of where i want the torque and low end grunt.
i do need to get rid of the stock downpipe flange though, i feel this would help improve matters

The VF24, 28 and 29 are literally the same turbo with a few small differences in there compressor wheel design, but they all more or less flow the same. If the VF22 is bigger, how can it spool quicker? If you look at the specs of the turbos, the wheel trim size's, area/radius ratio of housings and flow charts will show you this.
I think a VF22 on a 4E would jus' be good for a drag setup, i've seen a couple of dyno printouts and it would not make for a good fast street setup, it's not all about the power, it's about your powerband.
They are old turbos and many say they are inefficient and you can't put high boost through them, thats because they are made to work within a operating range, but to make near 300 hp from a vf24, 28 or 29 from 1.35 bar boost is very efficient i beleive, especially considering the size of these turbos (small).

if you read what i put they can and can bring compression down but thats why you have to dail them in most cams you dont just bolt in you can but if you want top power adjustable pulley is needed this is harder to do then most 16valves as they will have 2 pulleys as you can adjust one more then the other you cant with these cams so you have to get it bang on lots of road testing is needed best for somone on the rollers to set it up for you

what do you mean, decrease compression? ratio? or P max. surely not ratio, cyl size is still the same? and if it wer to reduce P max, that would probably be caused by timing being wrong, and exhaust v/v opening too soon?
these are just what i think, but small petrol engines arent my thing, so please correct me if im wrong..
