T28
 

Ive got my T28 and ive looked at fitting it bit of fuckin about but seems straight forward has anyoff u done it? i knw i need a s13 turbo elbow as the studing is different and also the boost pipe from the turbo and ova the rocker(if ne 1 has these plz let me know) and the oil pipes seem almost the same which is cool lol wot sorta pwer difference does it make? and will i get a lota lag?

As you sound like you're running without an intercooler you won't notice much difference in power, however power delivery will be smoother and further up the rev range. It will be a little laggy though, not much to write home about, certainly won't make much of a difference on the street.

Have you changed the plugs as well? It's well worth looking out for an FMIC setup as that let's you crank up the boost a little and will make a difference to power output because of it. There were a few for sale not so long back, I'm sure someone will pipe up if there is still one available. Don't forget that it's also well worth uprating your fuel pump with these mods as it's less likely to lean out running on a Walbro and will save you a piston or two!

After that I'd start to think about making it stop/corner better. Pound for pound good quality brakes and tyres are unbeatable for performance gains, makes the whole thing safe too!

What t28 have you bought?

It's one off a Pulsar GTI-R

yer from a pulser. wots a FMIC set up and wot plugs shud i use? soz if im being thick here lol its alredady lowerd n stiffend n i got pilot sports on! i wouldnt mind some nice shocks thou!
also im having problems mounting the actuator has ne 1 done this if so how?????? lol i also need a 200sx s13 boost pipe from the turbo as it is different from the siliva 1 n e ideas ???

fmic=front mounted intercooler

I have recently chcecked haw much the stock injectors can handle. 0.7 bar is a maximum preasure on a T28 turbo with no fuel system upgrade except walbro fuel pump. It leens to 12,5:1 at 6000 rmp. The maf shows 4.95 volts and u cant ad any more fuel.

How did you work that out?

With a wide band o2 sensor ecumster piggyback compter wich tell me AFM imput voltage to the ecu and a boost gauge. And i have a volvo 740 IC.

So if it maxes out at such an early stage how do the S13 owners manage 270bhp @ 1.2 bar?

It is worth noting that higher boost will result in higher fuel pressure so to some extent a reasonable fuel ratio can be maintained.
