compression motor and try and see how much power I can get without
turbo. I'm playing around with a sleeve design for it....and an
intake manifold.
One of my toys is an '04 G35. Honestly, I don't want to convert it to
a 1000HP car. I am not saying I don't want 1100HP. I am just saying
I don't want it in that car. Around '95, I turbo'd my first Nissan,
an se-r....hooked from then on.
I think pushing the limits of an NA build will be neat and interesting
not only to me, but to others. Personally, after dynoing a few
customer cars and my own, getting around 220 to 230 HP is not
impressive from a 3.5L motor.
Nissan had in my opinion an underrated 3.0L in the 300zx at 300HP.
Then, they went from a 3L to 3.5L took 2 turbo's off and claim over
270HP? I thought it was a stretch back in 2002. If my memory serves
me well, the highest we have gotten from an NA on our dyno was an Rev-
UP version that we tuned with an Uprev and got something like
260ish.....gained about 10HP/tq tuning. So unless otherwise coherst,
I'm doing an NA build.
OK, onto the sleeves. If a customer/our shop/employee set a
goal for more than 1000HP, I would highly suggest against doing a 4.3L
build. The bore is much bigger than what is needed to get the job
done. Jon and I were pushed to 103mm pistons to achieve his goal:
the biggest VQ JGY could make. Realizing that we went from 95.5 to
103 is a huge deal. I think that is what the original posting of JGY
was about in this thread. It's weird and awesome. Do the math, it's
actually more than 4.3L, I joke (I'm a atv dude) and say Yamaha would
call it a 4.4L. OK, so if the 1000HP was the goal, I'd suggest a 99mm
with those sleeves, maybe a 100mm. I would prefer the headgasket that
would be used with that bore as well. I might, I might even suggest a
non-stroked crank, but use a billet crank with double/fair
counterweights. The longer stroke creates more motor, but also
increases other issues that are not ideal. Realize that the reason
JGY went to a solid deck design was because 103mm pistons are bigger
than the water jackets/walls of the factory motor....much bigger. It
simply had to be done to get that size. JGY's sleeves will not/can
not fall because of the machine work done to the block. They simply
can't drop. I won't say that a headgasket won't fail inbetween the
cylinders in 60,000 miles though. Jon is taking that risk to get 4.3L.
The issue with increasing the bore on the VQ is the fact that as you
go bigger, you make the vertical wall thinner for the combustion
chamber. The issue that results with the JGY solid sleeves is that it
reinforces/joins the block together albeit while costing some money.
Not everyone dishes out $1000 for sleeves and $1000 for labor to
install them. I'm also NOT implying that the JGY solid sleeves are
the best answer for all issues. I think there is another option out
there that gives you smaller displacement potential, but also gives
you a stronger block. If I get paid to work this Sunday, hint hint, I
might know more about this idea.
After I decide on the sleeve design for my own NA VQ, I'll have more
insight, but for now................. if the goal was over 1000HP,
I would opt for around a 3.6L to 3.9L motor, probably not stroked,
probably single turbo'd and not twin'ed, VP C12 or Q16, and nitrous to
make it easy. Even if you take the NOS out of the question, my
previous description would still stand.
Jon's wish list included: 2 GT3076's, the biggest motor JGY could
make out of the VQ, and cruise control (that's what the customer asked for)
so..........who's going to push RevolvedZ into a 1000HP motor?
I'm basically calling RevolvedZ out! p.s. you guys know he sold his 300HP turbo'd KA for a VQ right?

haha i dont even know what i would do with 1000hp on the street! yesss it would be one impressive VQ , i mean if i had a purpose built drag car i would be all for it!
and i know i know i sold my fast car for the 350z haha but give me time... and ill be the fastest VQ at JGY

yea thats true, i mean it can be de tuned for the street, but on a personal stance i dont need 600-1000hp daily haha
we could make the same numbers and more with a smaller displacement/stroke, its fun being the biggest though!
and the TB48 has been a dream of mine too sir!

I have heard that comment a lot in the VQ community. A 1,000+whp VQ doesn't have to be a dedicated track only drag car though. Look at the Supra community. 1,000+whp street & strip cars are not rare for them. They usually don't run 1,000whp on the street. They typically run low boost on pump gas or E85 on the street and turn up the boost for the track.

I understand what you're saying about the 103mm bore. The AEBS and Darton sleeves have a maximum of 100mm bore. I wouldn't want to go past that bore size either on a 1000+whp VQ build. I like the idea of going 100mm bore with a stock stroke. However, my dream build would involve a TB48DE swap.
You certainly can make a VQ have well over 1000HP.......but we don't think Nissan's design behind the VQ was big power..... but more efficiency.
Comparing the Supra to the z33 is fair.........but possibly not the motors to each other.
Although, the RB25/26 doesn't come in a Z33 as we know, comparing that motor to a 2JZ is more fair. The 2J just has a larger following for it. And before we get into a (it's bigger). We do a fair amount of dynoing Diesel trucks.........almost always the 5.9L Dodge versus the 7.3L Ford........well you know where we are going with that.

we have been investing some time in a few other motor builds in the shop, wrapping up a stroked rb23, and a fully built rb26 getting started, but its coming back under the knife soon!

It hasn't touched the engine room in 3 months. This is a customer's car...........but the car isn't here yet. It's a customer's motor. He is not in a rush....but that isn't a reason why it's not done. He's patient........actually we are probably less patient than he is......it took him 13months to get us the intake manifold. (long story for another day) We did a short block build for a person outside the U.S. in that time frame with another set of these sleeves.
Several other motors ahead of him will be finished before his will.......there will be progress on his......but I wouldn't guess it would be finished in 3 weeks.
....speaking of which......have you ever been to JGY? You are welcome.
I'm sure the short dude will post photos of any progress......so hold tight.

JGY should definitely stay up on keeping everyone updated. Big claims were made, and to keep from becoming another White Dragon shop they need to follow up on them.
Besides that, not too many cars have been finished recently... Getting boring in the FI section.

were only new on this forum scene dont you worry,we produce
and trust us... we want this thing built/done too... and the car to be here so the install can get done. plus,we dont get paid on hopes and dreams! haha but were stoked about it...
we could post about the numerous sr/rb builds that have been in and out of the shop between now and then, but we figure its not the place for that.
