thanks for the info...
but bit puzzled on a few things...can you shed some light ?
standard bhp for these is 135 or thereabouts
you've quoted a guesstimate 250bhp atw which would equate to approx 290+ at the flywheel
how have you managed to get the extra say...150bhp running between 0.7 and 1.2 bar, with just just the modifications listed: hybrid turbo, intercooler, exhaust, pressure regulator, fuel rail, plugs etc
cheers

I know they didn't have one as standard
& how exactly will it make one 'hell of a difference,'
As seen in the spec, with other mods, a difference of up to (guesstimate) 150 bhp or more over standard bhp figures ?
...all you're doing is cooling the air for running additional boost, eliminating possibility of detonation...nothing more
+ it's only a cossie i/c that's being used, which is fairly small albeit efficient
am i missing something here....?

evo zero do you actually know anything about turbo charged cars??
the silvia not having a intercooler was feeding the engine with superheated air straight from the turbo- this in itself inhibits at least 60-70 bhp depending on condition of turbo that takes us to 190 minimum - r u with me so far????
then add a huge induction kit, 2.5 straight through pipe from the turbo, including downpipe, one turbo designed for a 2.0 litre, 16v car, intercooler from a cosworth sapphire, etc etc which then, as anybody with a modicum of mechanical intelligence can tell you, adds up to AT LEAST 250bhp.
ok?
now back on subject..... its for sale, interested?

some points from the above:
1. I wasn't doubting anything that you'd written in your spec....
just was puzzled...as i'm not totally 100% on the early silvias
2.It would appear that you've taken my questionning as a reason to be somewhat condascending and give me an explanation which is certainly 'interesting' ....
I'll run this past some experts on these engines, e.g. Silvia Engineering and Norris Designs to see what they make of it....
Fairly sure that they'd be very interested in how you've managed to get (your quote)250 at the wheels with the mods listed
3. by the way....my last Mitsi ran a 12.9 quarter at Avon Park on a damp track..so like to think i know a 'little' about tuning
...but thanks for the invaluable information written above ...especially the bit about gaining 60-70bhp from just strapping on a fairly small intercooler and doing nothing else....
There is no mention of a 'chip or ECU change,' increased fuelling/fuel controllers etc etc ......should I assume that these have been given attention in achieving your atw figure ?
& re: the car...i may still be interested...
cheers

Thats not how it came across at all
2.It would appear that you've taken my questionning as a reason to be somewhat condascending and give me an explanation which is certainly 'interesting' ....
Now who's being condescending??

<sound of knees knocking>
What are they gonna do if they disagree?? sue me?? am I supposed to be impressed or something???
3. by the way....my last Mitsi ran a 12.9 quarter at Avon Park on a damp track..so like to think i know a 'little' about tuning
Not really hard for a 4 wheel drive mitsi - I am sure Simon Norris can tell you this
...but thanks for the invaluable information written above ..
Now who's being condescending?? part 2

No chips available so the answer to this one would be no, thats why it has an uprated fuel pump, and fuel valve
& re: the car...i may still be interested...
And you think I am still interested in selling it to you??
cheers

no ...you're not on trial...but your car is
... I was a genuinely interested party...& was only asking for some ideas of how you achieved the power figures that you quoted, as anyone would....it's part of the buying process ?
but you seemed to have taken it all personally....
- shame...as these are open forums where performance & tuning issues are supposed to be discussed ...even in the for sale section
anyway...
good luck with the sale...which going by your spec list & pix should be fairly rapid
btw
i wasn't comparing myself / car to Simon Norris (or any other tuner)
...I don't have/want to spend £70,000 on an engine and drivetrain to achieve 807 bhp - as per Norris Designs
...and for all that money& power..he's only 2 seconds faster (a long time in drag racing but not worth the spend IMHO)
cheers

This thread has turned out to be surprisingly entertaining! Power figure kinda rings true to me, assuming a base of 150bhp at the wheels then running 0.7bar boost with ideal conditions should give 255bhp. Getting the ideal conditions is of course the tricky part but an intercooler is a good start.
Of course I have been known to not have a clue about what I'm talking about
Cheers,

Guessing HP output
I just don’t think that you can add the assumed hp gain for part A , part B and part C and expect to get any sort of realistic figure, all you get is compound error. Engine tuning is all about compatible and complimentary enhancements and a strict regime of measure, analyse, adjust, again and again until you are sure it is right then all over again. Quiet often what you may think is a sure fire major HP win may turn out to be a damp squib, hey even spending a couple of hours on a dyno should not be taken too seriously, I have seen HUGE differences between different shops (try nearly 30 hp on the same set-up)
Anyway sorry to hijack your car for sale thread I'll butt out now-- best of luck selling it.
Regards

entertaining:
that's good ....better than being dull !
am assuming your compliment extends to both 'speedfreak' and myself ?
power:
unlikely....
base power for s12 Silvia 1.8 turbo is 120-135bhp at the flywheel (depending on whether it has smog equipment)
....so approx 90-100bhp at the wheels
believe they run (?) 0.6 bar as standard boost
this particular car is running a t25 turbo
- which in itself has a maximum flow rate/bhp ceiling of 215bhp at 1.2 bar max

we have had a member reporting this post on a matter of princapal that the for sales section says it is for Z related items only
the guy in question is correct.
maybe we should have a seperate general for sales/wanted section
IMHO allthough this original post is not actually Z related it could be of interest to Z/ZX enthusiasts and has turned into a very interesting thread on power gain per £ value
I am begining to lean towards a seperate for sales section,
god knows we need as many posters on the almost silent forum to get other nonusers to stay here once they have registered
sorry to highjack thread but what do you all think?
