Says it for 350z, but would this spec set fit our g's? Hmm. It looks like the s2 is only for the z, but the s1 for n/a vq35's is for both the z and g--Anybody know of anybody w/ the s1/s2 set on?
Since it's S-tune, does that mean that installing it would not void warranty? Anybody know of any importers that can order individual items from the set? But 10k

 

10k

 

just buy the parts seperatelly. 10k is quite hefty

 

does it add much hp?

 

the parts seperatly might actually accumulate to the same amount AND since it's a S-tune part it means it can be warranteed by dealer!

 

I've been trying to find an importer that can get any of the individual parts from the s1 or s2 concept set, but have gotten no luck so far--can anyone recommend anyone or any company for this? thanks!

 

actually nm....i was looking up japanparts and it might run about 6k. still warranty sounds good.

the heads make the compression go up to 12:1 and with the valve and springs you are looking at much higher redline, dare I say 8K at least? since our car makes more hp around the top end, I could say it could make some significant hp but not as much as a turbo would give you. Also it turns the car into a 3.0 Litre displacement.

CYLINDER HEAD SPEC-2
High compression ratio cylinder head for race use. INT valve sheet inner diameter f32.The combustion chamber is cast and processed with the same basic application as the VQ30. Capacity was decreased from 56cc (Stock) to 46cc (NISMO). Compression ratio therefore is raised from 10.3:1 to 12:01. The intake and exhaust ports are optimized for their highest potential. The Spec -2 further increases the inlet valve diameter to 32mm, resulting performance greatly exceeds the Stock VQ35 Stock engine. Made to order (Take 1-3months).

this doesnt include the intake and the cover or the ECU

 

Good find Ivory! I was actually only immediately interested in the ecu, carbon engine cover and intake set, lol, I guess those items can only be had by ordering the whole set? nismo.jp list the S2 concept to only fit the 350z, while the S1 according to them is for both 350z and g35 coupes, but I thought the same engine is used

 

it lowers the displacement but increases performance without a turbo???

It lowers the displacement and the factory pistons therefore raises the compression. less space higher compression.

 

what are the #'s?
