What sorta KW does a non-turbo silvia have

[holdens_r_better]

How many KW does a 2lt non turbo silvia have and how can i do it up to get more KW wihout sacrificing fuel consumption

[holdens_r_better]

also how can i tell what type of engine it has on carsales.com i seen a few on there but cant tell if they have a sr or ca engine if it is a 2lt does that mean its sr

[nismoman18]

yes 2 litre is SR20 and 1.8 litre is CA18. the power figures im not too sure prolly around the vicinity of 120 odd KW at the flywheel, prolly 80-90 at the wheels. do it up just the exhaust and filter upgrade, u want sum serious power sum internals, or else forced induction!

SR20DE is in the order of 105kw @ engine.

thats for the NON VVT redtop engine.

www.silviansw.com for very useful info on sils and 180s

as for mods, exhaust, intake, cam shafts do a bit for the SR-DE engine.

there was a write up in a fairly recent hpi magazine of someone who had done adbsolutely everything to his CA18DE, cams and extractors were the most worthwhile. i think he still only made 87 rwkw though. i think 1991 is the changeover year ie where they changed from CA18 to SR20. i researched silvias a fair bit a while back because i was going to get one but i realised a skyline is better

That article in HPI, the guy had a later model 180sx with an SR20DE with VVT if i recall correctley.

They didnt make much power from that engine at all, they almost went backwards when they added the first set of extractors (lost a fair bit of mid range)

hey i had a excel with a pod and extractors and exhaust it ran a 16.3 1/4 mile and my mate had a stock SR20 silvia and i ate him by half a car lenght all the time.. i think the excel had about 60kw at the wheels. hope that helps a little.. mabee just to compare huh

[holdens_r_better]

i think the Sr20 would have a fair bit more kw then an excel

[banshee]

excels are only 900 odd kilos dry but..

i got 120hp at the wheels from my 2ltr non-turbo sil yesterday , no extractors , just cat back and pod , tuning and thats all ! Am building a 200+ sr20de atm . The thing is i have 115hp available between 4500-7300rpm !

Ok I've got that article from HPI in front of me.

Cat back exhaust - gain nothing

Custom 4-2-1 extractors - lost power "massive midrange hole in the power curve"

Custom 4-1 extractors - gained a little "lost a couple of top end kw, restored midrange punch"

ARC intake pipe - gained nothing "aim to change inlet volume to change the resonant frequency of the whole system, and cause either an earlier or later peak that increases power" sound interseting i think.

HKS 256 step 1 camshafts with timing gears and apexi safc -"remarkable gains" "88kw was the final figure, up from the initial 74 kw"

[Greg]

oh yeah and you were right nismodified it was an sr20

[Greg]

that pic was dyno graphs btw

Increase power without sacrificing fuel consumption?

Fuel + air makes power. You need more fuel and air to make more power. (generalisation, correct in principle)
