I visited AEBS today to see the pro spec series stroker kit (VQ35DE)

I had to see this in person, I talked to the head mechanic Paulus who actually I remember from back in 92 who was a honda guru.

1. The total cost of the kit is 7,800.00

2. Comes with 9325 custom billet steel crank. used in NHRA
a. the crank was very high qulity(see pic) overall stoke is
90mm(stock is 81mm)
b. according to paulus this bad boy should have no problem
with stock rpm revs in fact with rev limited removed the
engine can safely rev to 9k+ with tuning. Even though it is
a 6cylinder his reason is that the prelude and s2000 stroke
are 91 and 90 mm so that shouldnt be a problem.
3. The rods are x beam with internal oil inlet from the crank up
the beam through the wrist pin to squirt into the bottom piston these rods are made by Pauter

4. The pistons are FORGED,you can expect up to 26 lbs of boost for the 8:5:1 compression. no dyno result yet......(wrist pins&rings included)

5. As for the t sleeves thats where Im really impressed with the quality, although they did not have a VQ block there they did have the sleeves very heavy duty, they did have a nsx block with the t sleeves in it. As for blueprint and machine work he expect about 15 hrs labor at 65.00$ an hour. Me and paulus used to use Ed Hale in lakeside ca, he is know for his excellent machine work on race engines. Unfortunately its race season here and 6 cylinders and 4 cylinders are paper weights until the small block chevys are done. Paulus said the VQ block is are stronger then the supra turbo blocks although they are full floating cylinders
But im sure any good reputable machine shop can do this. I thinking to see what Benson Machine shop charges in the Los Angeles CA area?
My final Verdict is this...........Hi quaility, no doubt. Personally I would love to see someone(with money) do a NA build up with the higher compression 11 or 11.5:1 at a price tag or close to 8k without machine work you would be looking at over 10k+ by the time its ready to turn key. I would like to see HP and Torque numbers in the future, Since im married with kids, I will have to pass and maybe settle for the sc or tt and 6-8 psi.
For those with deep pockets, I wouldnt hesitate , the car is still new and im sure we will see many many avenues of horse power, but if you want somthing different ,,,,,,4.3L VQ sounds NICE!

Paulus heres your claim to fame ......

ether

any chance you could resize the pics a bit larger.. did they mention whether a NA build up would require an upgraded fuel system..

Can you reword that one again? It's hard to believe.

yes please resize pics.

I can't wait until we see some HP and torque #'s from this setup with FI. N/A #'s would be good too. I'm thinking about selling my acura and dumping some money into my zed. Most likely it will be the greddy TT kit but who knows

PAULUS THE TECH

Paul said the VQ blocks are stronger then the supra blocks. The way they are treated is like a forging process.....I know its hard to beleive, but this guy has been around awhile. pm me with any more questions- thanks

Not to say that what he's saying isn't true, because I really don't know for sure, but his reasoning is flawed. Stroke numbers alone do not tell you anything about the revving capabilities of a car. The rod:stroke ratio is the only thing that really matters, although a smaller stroke does mean that there is a greater chance of having a good rod:stroke ratio. He probably knows this, I'm just wondering if he's actually brought a VQ35DE up to 9000 rpms and saw how it acts at that level.

D'oh

Don't forget piston mass either. S2000 has 2.0L with 4 cyl = 3.0 L with 6, so with a 90mm stroke that means the bore is less than ours (since we have 4.3 L with 6 and 90mm stroke). Therefore our pistons will probably be quite a bit heavier, and this added mass will definitely affect the ability to rev. Doesn't mean it can't happen though. Sure would be cool to have a torque curve that keeps going strong into those higher RPM's.

Would be cool to have $10,000 dollars to make it happen, too.

-D'oh!

Hey I can do it .........do you want a 15 year year old......hes good for about 20grand a year

stroke is more important than rod ratio. rpm capability is determined by piston speed which is a funtion of stroke times rpm. ask paulus how high they rev the drag honda motors he builds, which all have **** poor rod ratios. a good rod ratio is beneficial for piston side loading, but it's not super important.

350z_taquito

they are semi-forged. after they are cast, a male end is pounded repeatedly into the opening of the water jacket (female end), hence internally forging the block. you obviously can't do this w/ a closed deck block.

Very interesting information. Let's try and keep this bumped, eh?
