if that's the case, lth, ecutek, e85, and plenum mod and you would be at like 360-370whp, but it's not lol

i still want to see you hit 400whp n/a :D that will be exciting.

Elmo370z 08-28-2015 12:53 PM

Slowly working on it, long tubes and oil cooler coming after i get back from korea. Then cjm manifold if he comes out with one, and jun cams if i can find a valvetrain upgrade

Elmo370z 08-28-2015 01:49 PM

Jwt is in the works to upgrade the intake side as well, but that is a while before it hits shelfs

What dyno? I'll be doing e85 within a week or two. So far my gains were good then they fell flat. However I did switch dynos. Any number I see above 330 I'm like :ugh2:

MILENKOGT 09-01-2015 06:50 PM

What is JWT doing to upgrade the Intake side? of the VVEL?

Elmo370z 09-01-2015 09:01 PM

Special cam conversion, all they said

derraj06 09-03-2015 03:46 PM

In the past JWT swapped to HR heads to get around VVEL. I'll be interested to see what they come up with for VHR heads.

Elmo370z 09-03-2015 06:43 PM

Yeah, they make a kit, but it is alot of work. I rather put that into my build

Spooler 09-03-2015 10:02 PM

I am so tempted to go NA because not many do. Cams would be nothing but the price of the cams for me, Install would be on me. I love how 1slow370's car sounded. It sure has me thinking.

Elmo370z 09-04-2015 12:26 AM

I bought a spare block, to follow in his step, there is an dry sump setup thst is in prototype right now and would cost around 4 grand.that's not including the tank and an fittings. But i know someone who makes them so i can get them at 5-10 a piece. Only thing is if there is a company willing to put the time and effort to come up with a badass manifold that makes power. Ecu tek has already proven with a good tuner, you make more power than with an uprev tune. If you install the cams ill. Drive up to ga and pay you to n put them in for me.

Spooler 09-12-2015 11:17 PM

I have been researching the way to get around the need for a dry sump. The only way is to keep the rpm's stock. There is an old saying, "There is no replacement for displacement". For a dry sump, it would run for a kit 5K or so. For a stroker kit, it is about the same. Both will need to have the engine removed. IMO, a stroker kit would be a sure beat and the way to go with cam upgrades. You can increase the compression ratio at the same time. Labor is on me, so that's not a big deal. You could do LTH's, lightened flywheel, clutch, Cam install, ported heads, or whatever you want while you have the engine out. It would be easier to do the cams and LTH's with the engine out anyway. Cost for everything would be about 7-8K. Just a thought.

Elmo370z 09-13-2015 11:36 AM

Yeah, i have a guy here who could get me with the build, time is the issue for him. Im sure there is a way to get around the dry sump, just would take a couple motors to find out.

BGTV8 09-13-2015 04:04 PM

The alternative to a dry sump is a wet sump with external oil pump to overcome the limitations of the OE oil-pump.

Elmo370z 09-13-2015 05:40 PM

Welp there you go

Eclipz 09-13-2015 08:48 PM

Why have either a stroker kit or a dry sump when you can have both :tup:

Cost, if your going to sink that much in it you might as well go TT.

Elmo370z 10-09-2015 07:40 PM

Well just ordered my long tubes and oil cooler. Tune coming up in a couples months, why, because im going out of the country for a month. Next step, if my csc doesn't go out, ipp heads, jwt stage 2 cam and valvetrain upgrade, manifold.

Elmo370z 03-21-2016 12:21 AM

Parts collecting. New 70mm TB's coming in the mail soon. Next is Jwt stage 2 cams and upgraded valvetrain. Next thing I'm thinking over are injectors, I was leaning toward ID750cc.

Hello where can I get the 70mm throttle bodies??

Elmo370z 03-25-2016 04:12 PM

EPS tuning. They ran a group buy, its over now. But you can still purchase them

lhinojos 05-26-2016 10:44 AM

This dude was running 420hp with a slightly built vq on 53mm itb's. He's going for 450 n/a

Might be some help?

Thats a gnarly set up. I cant afford dry sump and hr head swap to do ITB's. I have plan next year to come close to 400whp on the vvel heads and still staying NA.

njobe89 05-26-2016 12:04 PM

that's pretty amazing

Thats sasha from onpoint dyno. That was testing for a BGTV for his build in Australia. He is also running a motec, that itself is like 10 grand. That car is a vq35 with a 370z oem crank i believe.

Correct, Sasha's engine is a VQ35HR block, race ported heads, JWT GrandAm spec pistons (12.5:1) and OEM 3.7 litre crank. My build is essentially the same but with a 92mm stroke crank for 4.0 litres.

Sasha runs race gas, I plan E85 so I can go higher in compression (13.5:1 at least).

Dieselg37s 06-02-2016 12:42 PM

I saw that video he has a nice setup is he running a dry sump as well?

Elmo370z 06-02-2016 02:02 PM

Yes. i believe so, to run and sustain running that much rpm. There isn't another solution to spin the motor that hard for a prolong period and want reliability.

Elmo370z 10-27-2016 06:11 PM

The build is in motion, just got a parts lists of everything i want. Now i just have to stack dead presidents. Target time August 2017.

I'll just take this stack here. :yum:

4.5 stroker n/a
with all the toys on it.
2017

I been following your build and say the least very excited about it. You still sticking with the vvel heads? Wonder how much power that v-8 ooo excuse v-6 will make.

Elmo370z 12-27-2016 06:02 PM

So are 1050 cc injectors too much for NA build?

Elmo370z 12-27-2016 06:04 PM

I plan on using e 85 for the most part

Elmo370z 04-08-2017 12:19 AM

So the custom crankshaft will be placed in a few months.

Alchemy 04-08-2017 09:35 PM

Im currently debating what direction Im going to go in for my next project. I currently have a bent rod in cyl#3. Im thinking of either throwing in used motor or going with a built stage 2 IPP longblock Stage 2 VQ37 Long Block Engine - Nissan 370z/Infiniti G37 - Import Parts Pro
With full bolt-ons how much power you guys reckon it would throw down? Is it worth it? Way I look at it is I have to buy a motor one way or another and its not much more than a used to buy IPP's built longblock. IPP says depending on the mods the stage 1 should gain 20-40hp over stock. Not sure about the stage 2 which has the JWT cams. Any input you guys have would be nice.

Depending if you stay with stock compression or bump the compression will make a huge difference. Also depends on supporting mods to work with the upgraded cam. Only one person has done a stage 2 cam and made decent power, but he had a dry sump to support the extra revs safely and some custom 1 off parts. If you were to run straight e 85 and bump the C.R. To 12.5 or 13.1 you would make some awesome numbers and probably break the 400whp barrier. But that's my 2 worthless cents.

Not trying to chase 400whp with this build like you, Elmo. Since I have to dump a new motor in the car Im wondering how that stage 2 would perform kinda as is. Id be running stillen cai, z1 headers, test pipes to stillen cbe. 11.5:1 compression. How Im looking at it, it kinda seems worth spending an extra 2-3k over what it would cost me to buy a used motor and about 1.5k less than a new one from Nissan. Dry sump, e85, not trying to get all that involed. If I could squeeze 350-360whp outta that I think I could be satisfied. Although I wish I didnt have to replace her motor otherwise these funds could be going towards a BP turbo kit...

You will need larger TB as well ........
