N/A build

Elmo370z

So i'm buying a block after this year and plan on building the motor at a tortoises pace, I would like to have a beast street car with occasional track usage, never going to drag the car . I don't want to stroke the motor and I would like to keep the VVel heads. Would like some guidance. Here is what I'm thinking please feel free to correct me. Forged carrillo pistions (compression ratio??), arias or wiesco pistons, racing engine bearings, jun cams, and along with the other bolts ons, bigger fuel injectors and intake manifold and dry sump.

Im sure you've seen 1slow370z's build, some good info there you can build off of. Unfortunatley I dont have any knowledge to share, but I wish you good luck

N/A build eh? Well the number one question will be what are u building it for? track? Drag?(although ill doubt Drag)competition? ... w/e it is, it all has its own setup.

u need 2 convert to e85 setup with return fuel line and a pump that can has more flow for ur upgraded injectors, also setup 9:1 comp ratio and 4.5L internal setup an all. whole list cost lots. damn lots...raze rpm limit to 8.5 maybe 9k = 450hp?????

why you dont check first how much you are going to spend upgrading your Z with a N/A setup VS installing a TT or SC setup... And how much whp do you want? my experience is that we always want more power on our cars hahha!! and in my case im just going to install some N/A parts like intakes, catback and maybe a tune.... when i finish that im going to start saving to go with a TT setup... just my 2 cents!

imo, i'd ditch the vvel, go dry sump, and rev that b*tch to 9000

I would love to see the results for these...If you do decide to go that route, can please do a dyno of just the jun cams with all the other internals you want but if possible with no other bolt on mods. Thanks

Elmo370z

Yeah his build gave me a good idea on where to start

Elmo370z

I don't want to drag the car, I rather it have a set up for the track so I could take it out their every once in while. Far as power I know I'm going to have to rev the **** out of it to make power, I would like to have 400-425 whp on a NA set. I know the cost to attain that much power out of a NA would be a the same as going to F.I. route. Personally I love the way an all motor high revving engine speaks

nismolucino

Any off the shelf piston is going to be too low of a compression for n/a power.Honestly youd probably be fine staying on stock pistons if your not looking into stroking the motor. And as stated before Id really get rid of vvel if your going that route. Do some hr heads and cams and then youll make power. Dry sump would be awesome but is really expensive, maybe look into the upgraded nismo pump it should handle higher rpms.

edub370

i think the nismo pump will still have issues above 8300

^^^ agreed. I would stay with stock piston, but if they let go at high revs. I'd be pissed to have to tear down the block again. When I go to build the motor I want to do it right the first time, instead of spending countless amount of money trying to take the cheaper route. Plus no one has any evidence on how high you can spin the stock internals, plus the durability at those rpms

I agree with that, then best bet is to look into some custom pistons maybe see if any of the companies will make you forged ones with oem compression or maybe a little higher.

carlitos_370z

want to see what you are going to do dude!! sounds very good

Spooler

That engine is going to cost more than a FI setup. Mucho more if you want to get near 400whp. It's not worth it.
