hi a mate has given me a sr20 turbo and manifold and lines off his SR20DET pulsar motor. could i use this on a A14 motor or would it be to big. only running stock internals and low boost. it was a freebie so i would like to use it.

yeah give it a go for sure... you will have to fabricate a manfold etc but I reckon it would be fun

i have this turbo on my a14 and without engine mods and some boost it really is too big. i run 12psi with turbo cam and pistons. it is not on full boost until nearly 4000rpm.

just to let you know there are at least 3 different turbos that came on a sr20. the best one is frm a s15 200sx. is a little smaller but more importantly has smaller air ratio on the exhaust housing so spools up faster.

I think you'll find that the S15 version is larger but due to it's ball bearing core will be more responsive than an S14 T28 bush bearing version. The S15 turbo will not be any more responsive than the T25g off the S13 Sr20 though. The T25g would be a good turbo for the A14 even if a little big. You could still keep a relatively high compression ratio improving off boost response because even running this to 14psi etc on an A series will be well within the efficiency range of the compressor meaning relatively cool inlet temps.

i have one of each of these turbos and the gtir one is definately bigger. and yes the effeciency on that turbo runs out at about 18psi

Yeah my mistake, the Gtir version was the biggest released on the SR20. I was automatically thinking S13 for some reason. One of them probably would be a bit too laggy for a street car on an A-series.

Mate all sr20 turbo,s are for 2lt not 1.4 lt all are too lagey you need a nissan exa turbo (t02) it will suit the motor the best but still as hard to fit i can do pipe work if your in the sydney area

any turbo that is factory would best be described as conservative. they give a bit of power but retain good economy and reliability. we are not talking about factory fitting. we are talking about performance upgrades! where economy and reliability are sacrificed a little for that word that puts the sparkle in the eye! 'performance'. the turbo you mentioned would be lucky to wake you up and i think most people would find the return very disappointing for the money and effort they put in. the gtir turbo on my car makes 150hp on 12psi at the moment with potentual for 20psi of usable, drivable power around the corner. you are not gong to get near that with the mentined turbo.

well good luck then

To true picko, e15et turbo is an old designed inefficent lump, had one on my exa, turbo only did 30k kms before smokey again, dont have a good reputation for lasting long, getting rare too, stuff paying $400+ for one. Id say consider ct9, ct12 from twin turbo supra setups, forrester turbo etc for a mild responsive spice up, and maybe tdo4l from late wrx, t25/g, heck kkr 280s are cheap new and would be plenty big for a big hp A. I wouldnt think about paying more than $400 for a GOOD used turbo such as above ones when you consider the prices of new ones are only heading down!
