Those are the Nismo R-tuned cams. The Nismo S1 cams(276/256) give around 30 rwhp with tuning. The problem with a fully built NA car is that it becomes less streetable the more you push for power. I have found with very radical cams the car will die sometimes under slow driving conditions. A good computer tune can help out but it still may have problems. Also if you go with high compression you may need to put higher octane fuel. So in my opinion it really isn't worth it for a daily driven car because of the inconvience. For track use I think it definitely is worth it.

 

Cams and compression play a integral part in how the motor is going to run and react. Heres some technical info on what to be carefull of. 10:1- Used and built as the 9.5:1 engine with more than 220° @ .050 lift cam. So a s1 cam may not be what I am going to get. Probably might have to have one custom with custom grind for this motor.

Thats the reason I want some questions answered before I go ahead and start building this motor. I am going to be running 91. I have to be carefull with compression ratio b/c with a 12 to 1 I need at least 38% nitromethane per volume I would need to run a minimum of 105. motor octane. I would be sure that it wasn't going above 11:1 because that would be cutting it really close even running on 93 as a daily driver. So I am doing my research on what the Squish/CC of the motor will be after head gasket, head work, stoker kit ect ect.

Hopefully Tommy K will email me back today and hopfully already have all this reseached so my lazy *** doesnt have to pull out the calculator tonight

 

I wish I knew the calculations to decide exactly what the perfect cam is for my application (93 oct), I'm basically just judging based on other board members experiences at this point. I have a nice book discussing boost, Maximum Boost by Corky Bell, but haven't found one to answer my NA concerns. What book would you guys recommend to gain some knowledge on NA fundamentals and maybe some engine build-up basics?

I guess these are the programmers.

 

Also keep in mind that those GAC motors require frequent rebuilds.

Oh -- that the JGTC Z does not have a VQ. It's a twin-turboed 300ZX 3.0L.

 

yes, it's a VQ

VQ30DETT to be precise

300zx has VG engine, and it never run JGTC that I am aware

 

Right. And that's the JGTC 500 350Z. The JGTC 300 uses a VQ35DE.

I am using Nismo S1 cams + nismo VTC units + nismo valve springs + motec + headers + cats + nismo exhaust + pulley and no problem with the street driving problem at all.... pulling out 217rwKW = 295rwHP on the loaded dyno dynamic dyno machine... so I guess 300rwHP is not that far anymore after I finish my intake mod (doing it now)...

Wow that seems like the same path I want to take. However I can't afford to go all in right now. If you could recommend one mod I could do which owuldn't require additional mods to work (ECU, Valvetrain etc etc) which would it be? I'm thinking of having a set of long tube headers custom made. I want to spend about $2k or so on a mod by the end of the summer.

 

Instead of custom making headers ... why not just go with XERD long tube headers. 16whp gain.

 

Someone needs to come up with a LS1 swap kit. The LS1 RX7's out there are amazing and I've seen swaps into Miata's, so it would have to fit under our hood.

-Mark

 

Anybody else think this # is sort of low?? A memeber on this thread from Puerto Rico(forgot his name) reached the 300+ mark with less aggressive camshafts and no standalone.

 

He has not reached 300rwhp yet. He was at 295 as well.

 

and I think we cannot compare the dyno number actually... because those tests were done on different dyno machines with different dyno run conditions... just like mine was done on the load dyno instead of the inertia type dyno and as I know... the inertia type dyno's output is around 10% more than the load dyno output (I might be wrong)..

BTW... what is LS1 really? I don't really get it though....

cheers,

LS1 came in Chevrolet Camaros and Pontiac Firebirds. Do a search on Yahoo. 350 c.i., very easy to make power on them.

 

THanks mate!!!

Alright..... Air intake myth BUSTED officially.... done my intake... and no effect what so ever.... the power stays the same.... and now what.... hahahahha.....

This is what we have done to the intake:

1. 84mm bore diameter intake pipe per Nismo (integrated MAF sensor)
2. Larger bell mouth in the standard intake (go down to 84mm at the end)
3. Modify air box
4. Dyno tune..

Same power... (lost 1 rwKW... at the top and a few at the middle range).. since different dyno outputs on different days cannot really be compared... but those are considered as the same power (only 1rwKW diff at the top end, might due to the colder weather)... no gain or loss...

Pics are here... enjoy them!

cheers,

richie

 

Did you have a bored throttle body also?
