the t28 on the pulsar exits at a different\place to the 200sx s14 one. to make it fit the s13`that i had , i rotated the core , then just plumebed it in using some braided oil and water hoses. hardest bit on the nissan is getting the manifold off.

 the t28 from the pulsar is the one that u want , as u get a slightly better spool , and it will push more boost b4 it gets past the point of no return for the boost u r pushing.
as for the intercooler, the nissan one goes up the runs to the front of the car at slam panel height( i used a saab one), standard ones go into the wing. the other way was to fit a front mounted hks or hks type /2wd cossie cooler as this has the inlet and outlet at the bottom, it was more or less a case of just making up a few bends, but this was usallay achivable by using the orig bends and a few cuts here and there, but nothing to hard or special, bends from a saab 9000 intercooler and pipework may come in handy though.ÂÂÂ

the cossie turbo has the same iirc, exhaust housnig but thats about it. plus it uses the t3 mount which is different to the t25/28 type.
your t25 hybrid will be good for 250 bhp
a t28/hybrid from 280/330 - 350 depending on spec type used.
the figures i have given you r proven figures using real world cars, ie my old nissan's , but they assume basic mods, such as sir filter, zorst, remaped ecu etc.
hth
want any more stuff pm me, as i maybe able ot help source a t28 or t28 hybrid if u want one.
maybe u could pm some info on the turbo conversion for the 16v , as im intrested in doing one to my 16v, but i want to retain the kjet

i take it a 5th injector would do the extra fuelling , if a little bit crudely
