400 whp on N/A VQ possible?

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

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 ........

ThAt shouldn't be a problem. Maybe look at a set of long tubes for that aggressive cam

Elmo370z · 04-09-2017, 08:27 AM

Didn't see you had a set z1 headers

They arent on the car yet. Going on when motor gets pulled. Id go long tube but I need to be able to throw the cats back on just incase I have issues with inspection (NJ). I havent had a problem yet but you never know in this god forsaken state.

Elmo370z · 04-09-2017, 10:54 AM

You should look into EPS TB's since you're bumping the compression ratio up.

How is your build going? Also not sure bigger TB's will be useful when the intake manifold is still necked down to around 60-65mm. Valkyrie guys tested bigger throttle bodies on stock manifold and it moved the power on the curve, didn't add any.

Also, with this dead thread revival, a few NA builds are supposed to go on the rollers in the coming weeks shooting for high 300's. My time attack build will be following these footsteps. Cammed, high compression, 8k build, stay tuned! MAKE VQ'S GREAT AGAIN!

Valkyrie has just gone to buying Jim Wolf built long block motors. They make 400 whp.

True but that's with doing the HR head swap. It seems easy to get to the 400whp mark with HR heads just expensive currently and not very well documented. One of my other buddies that is basically going down the same route I am just made 370whp/300tq yesterday without a tune to adjust and dial in for the cams/pistions/headers set up. Hes hoping to be close to 400 after the tune. Also be on the look out for MotoIQ. They are doing a cams/pistons/e85/ported heads/header build in a few weeks as well.

Right on! Excited to see how this all unfolds. The best of luck to you on this journey.

So just to get this out there, I will be trying to get out in the public more via my Youtube channel @ Austin Hertel. Most of my videos now are just fast lap videos from the weekend. Going to try to do more videos with myself in front of the camera talking about the new 2020 livery and the 2020 build plans for the off season. This should help me grow as a grass roots racer as well as get my build partners/sponsors some more spotlight. They deserve it!

Currently I am at a cross roads. 370z motor build with VVEL heads and try to get to 400whp/300wtq OR 370z w/ HR head swap and motor build to get to 400whp/300wtq. Just to leak some more info, there might be someone working on utilizing the 370z harness and ecu tuned on ecutek to control the HR heads. Previously people have been using 350z harness and ecu to make it work.

Nik Sohoritis and myself both are content with stock TBs and I personally recommend steering wide, WIDE clear of the EPS set. My set was promptly disposed of and Z1 told me they've had several sets come back. They won't reset and had my car acting way funky. I reached out to EPS about the issue and he basically told me Jon must not know how to tune.

Do what you like with your money, but EPS will never see another cent of mine.
