Putting in the new lump next weekend and was just wondering what power i should be expecting from it.. Just a guess


1995 WRX
TD05
Z4
Blitz SUS induction
SARD BOV
Race radiator
i pressume 380 injectors. (Whatever is standard)
Sports cat downpipe
De-cat center section
Racebox Backbox

 

260ish

 

Really?

A friend of mine who is running a W8, TD05 and de-cat zhorst got 275bhp on rolling road. No other engine mods.

 

W8?
Depends on the engines health when i swapped to the z4 from my early 93wrx i made a little less power but the the fuelling was a lot better and was a much smoother drive.
R/R figures are for pub talk imo.

 

W6 sorry.

yes agreed, it is pub talk, however its good to know

 

I thought the 95 WRX was 260bhp as standard?

 

how much boost tho?

std with a Z4 is approx 13.5psi

 

imo as long as the car is running safely that's more important.
The Z4 was rated at 260ps when the car was new,so a few bhp will be lost over the years.
Is the Blitz sheilded from the engine bay heat ,that will be another loss of power but you won't know until you put it on tyhe r/r
when you say new lump do you mean rebuilt?

 

i have no idea what standard figures are

 

yes rebuilt with race bearings.

 

12.71 dropping to 11.78 @ 6600

 

95 wrx is 258 bhp standard. the z4 ad td05 are standard items on that model year.
the rad wont make any difference on the dyno nor the BOV.
The induction kit could loose you power not gain it due to heat soak.
the exhaust sytem will add a few bhp. id guess 270bhp

 

hmm ok cheers for that.

is a heatshield a good idea then for the filter ?

 

yes or just returning it to standard airbox
