-- Posted by Bobster the Lobster at 11:29 am on June 28, 2008 How much do you think swapping a Spec-V engine for my 1.8 Nissan Sentra's engine would cost? Roughly. Also, what do you think the pros and cons of this would be. My Sentra is a five speed.  If that helps. Thanks. -- Posted by Crazy snake at 11:31 am on June 28, 2008 Expensive, v-spec engines are pricey, just buy a good power intake system if you're looking to improve the performance -- Posted by Holden Commodore at 2:29 pm on June 28, 2008 Well first you're going to need the engine, likely a different transmission, the computers, the wiring harnesses, you're going to need someone to do the swap.. it'd be at the very least a $3000 job. -- Posted by hinshawwrx at 3:04 pm on June 28, 2008 Quote: from Crazy snake at 1:31 pm on June 28, 2008 Expensive, v-spec engines are pricey, just buy a good power intake system if you're looking to improve the performance Depending on what performance levels the owner is going for an intake would do jack squat. You gain roughly 5 whp from an intake, give or take 3. Even full exhaust, intake, and a few other bolt ons won't give the true effect of a swapped motor giving the point of new motor having more than 20 hp. -- Posted by Gonzalo at 5:03 pm on June 28, 2008 I have a b15 sentra too. I think there's better options out there.. the Spec-V is not exactly reliable. and the QG18 likes to take boost, so you can turbocharge your 1.8, or maybe get an SR20DE.. they love mods too. Heck, there's even a kit to swap in a VQ35. -- Posted by emo sux69 at 4:16 am on June 29, 2008 The best eninge you could put in a sentra would be a RB25 I would think. There not that expensive too(alteast here) and can make 200hp stock n/a, and have a massive aftermartket.
