- what different S15 SpecR engine compare wth S14 SR20DET engine..what i know so far..S15 Spec R brake booster bigger, Injector bigger 4++cc, S15 got better turbine than 14, both oso got VTC or VTL, ECu not sure...different driveshaft need to hybrid, wiring maybe different a bit...any ideas guys...coz if S15 hcut still expensive i will plung in SR20DET black top from S14...any of u guys do conversion like this b4...coz need to prepared b4 do conversion....anyways thanks for advise given...:)

price after converting is more expensive than buying a Spec R itself...plus many factory installed items is nothing u can do from outside...

i get my silvia below 80k if buy s15 spec r hcut and convert still cheaper...and if just put s14 more more cheaper...i'm not doing it at sunway area which for sure cut troat price...coz outside sunway still got so many good tuner,installer and more creative which for sure more cheaper...for the spec r bar and bracing all can bolt back to spec s problem only bar or brace in the dashboard..coz that one i need to check first..this what i know from overseas forum..

S15 Spec R just around 90k
S15 halfcut is around 10k
S14 halfcut is around 6k


Cost is concern. originality also concern

you buy S14. your labour to fit it also a concern
nothing can used back on the car
Meter cannot use
need to wireup from your ECU to meter.. there goes the messy wiring part

you buy S15 halfcut.. all part can be used and plug and play
no messy wiring
6 speeder compared 5 speeder

I suggest you bolt-on turbo the SR20DE which more cheaper and powerful than SR20DET~

s15 meter can use bro..that easy job...ppl analog meter oso can put digital meter if know how hehe...i can get s14 engine lantai RM3k, use back my 5 speed gbox...6 speed s15 gbox known got problem when reach more than 330hp...wiring not an issue (just make it neat and follow OEM style wiring)..nothing impossible bro...in malaysia all can do one..
btw i agree nowdays s15 can get RM90k but rarely..if RM90 how much deposit to put surely around 15-20 or 30k....and for BOT...to make it sustain high boost and daily driven..sure need to spend more than 10k...coz i already BOT my previous car...a lot of problem if minimal budget...for ppl minimal budget like me S14 engine is cheaper to maintain, easy to find parts...and got so many performance parts....so bro this is what i thinking...maybe i'm wrong...
