Is warm milk still talking? Did you not read what we wrote? 380RS in japan runs on pump gas and has 395 n/a hp. It still retains factory intake manifold and TB's.

Jeremy doesnt have sick cams, or a crazy ITB setup except those RSX's do. It's cheaper to mod the hondas because the parts are easier to find and there is a market for it. Most folks supercharge/turbocharge a z, they don't run n/a.

 

If only we could run k-pro.

 

We have something better its called HKS F-con, AEM EMS, Motec.

 

I feel you.

 

It's just too pricey. Owners would rather spend 10k to get 500whp f/i rather than 320whp n/a .

 

500whp f/i is a dime a dozen, you get way more attention with 300+ na, at least with Z's.

 

Maybe on the internet, but in real life, a 500whp f/i'd Z is nothing to scoff at.

 

i'll just shut up till i c results with wild cams and some real headers, cause otherwise this thing is never gonna end

 

Yeah but 10k in N/A mods? Most people will laugh. Some of us do like the bragging rights therefore we still persue it.

 

well said, thats exactly right. here is why i did it. i wanted to hit 300 on a dynojet. i wanted to run 11s NA. it all happened or is happening pretty easily.

i also have shared EVERYthing i have done. its like public R and D. i am doing this to help other people not make costly mistakes that i can make for a lot less cause i own a shop and do all my own work.

cams will be next and will be sick, i will add in a few other things and get some more air in there. i have been talking with Lance Hayward about doing some ITBs for me and depending on cost, that might happen.

there are SO many stock parts still on the motor, i mean, i am running a stock computer with a utec in there right now. the utec doesnt even put the same timing figures in everytime for me. it has a bad habit of putting in either the value i have, OR something lower for timing. if i can get the greddy vmanage to work the VCT and ditch the DBW then i am only 1000-2000 away from a full standalone.

i think 400 is very possible. 350 is in the near future. i believe i could run 10s all motor as well one day. i just have short attention span.

i am just about ready to put my turbo 400 on with a 225 shot like i said and have the car go high 9s...

take this for me not braggin on what i am doing but helping push forward by sharing...

 

You can't win. ANything you do isn't going to be good enough.

JT I think you have something going. And I would hate to see it stop. But I see what you mean with the attension span. This just brings the NA game to a whole new level. I just can't wait to see what happens with the cams your going to throw at it. Keep the journey going. And remeber I am intersted in the NA build

 

yeah. I say we start a "Jeremy's N/A build fund" on here. I wana see numbers with 272 profile cams, crawford heads/tests, full exhaust, etc etc etc !! GOGOGO!

 

Subscribed~ I, for one, am very interested in Jeremy's R&D efforts. Please keep up the great work! :-)

 

The RSX / K engine that IPS put together was not equipped with ITB,s when making the 360+ hp.
I know, as I made the ITB systems and the plenum manifolds they played with to make those numbers.

The 52m/m RSX ITB system is capable of 300hp,
but it was a plenum manifold that was used to make the 360+,
And that was with very high compression and alcahol for fuel.

It's funny "someone" got a hold of me the other day,
to see about manifolding for the VQ35.
So I came on here to see what was going on in the VQ world,
and here are people talking about Honda K engines.

A completely different engine from the VQ35, which has no vtec or ivtec.
The VQ engine has fairly tight heads (small) compared to the Honda,
but the Honda only makes big ports work with the vtec cams etc.

To make big power out of the VQ35 N.A.,
you will have to open up the heads quite a bit and rev it up.

What intake system works the best to make good power in the VQ.
Time will tell.

nice more techs to the NA party it can only help man

 

I would not call it fully built...it has cams that are not much different from stock

once cams go in and a proper set of headers, I think your opinion might very well change

 

I've seen 1....ever

 

Not quite all of em...just maybe the ones you've seen But I know what you mean

There are a couple of legit 300 + whp cars there....not many, but a few

 

EXACTLY

He's tried out a whopping 1 set of cams and 1 set of half assed headers. The only thing I would have done differently to Jeremy is the compression, because, as I'm sure he'll agree with, that high CR is doing nothing for him as of now (could have likely been achieved with a far lower CR). Other than that though, he's sort of figured out in the past few months what many of us have been slowly learning over the past couple of years (which is how long some of us have been creating our NA cars behind the scenes). It's an experiment at this point for Jeremy as well as the rest of us. I think he deserves kudos to give this all a try and see what comes out the other end.

As for the K20 and its power potential...any way you slice it, it aint cheap to break 300 whp on one of those either.

 

There is so much more room to grow with NA power. The first Nismo VQ35 put out 450 hp at the crank when it ran unrestricted for the Dakar Rally. Now RJN is racing a GT2 class 350Z making 510hp all motor @ 8,750 rpm, and 330lb/ft @ 6,500 rpm unrestricted. (check the new Nissan Sport magazine) The tuning and breathing options just aren't there yet for us mere mortals to make big NA numbers. The fact that Jeremy has done so well on his own with very minor mods in comparison is a huge testament to what can be done with this VQ engine. As he said, a better system to control the cam phasing and a lot of time to get it right would make some impressive gains- but he's only using a UTEC right now for crying out loud. Put some tuned headers on there and a better flowing intake design, more agressive cams to push the torque output higher in the rpm band... it's pretty amazing to think about. If he could get his torque up to 250 lb/ft at 7500 rpm, he'd have about 360 whp. He's really not that far away from being able to hit that.
