Ok so im getting a built block now which one should i get?? Is there a better one?Below are a couple i found.

AEBS 4.3 liter Stroker Kit for VQ35- http://z1auto.com/prodmore.asp?model...ine&prodid=926

or get the SPeed Force Racing shortblock - http://www.speedforceracing.com/prod...y_g35motor.php


Both kits are about $7K so price doesnt matter.
1.)I heard with the AEBS i can Rev up to 8500RPM safely.. Can i do this with the SFR?
2.) The SFR says its good for up to 1000hp is this the same with the AEBS?
3.) Whats Tsleeve Technology (aebs) VS. Darton Sleeves (SFR)

get the 4.3 to **** everyone off

no matter what quality internals are used, I dont believe that you can rev that engine to 8500 with such a rod/stroke ratio. Reving such a stroked VQ35 to 8500 w/ FI is quite hard.

Also I didn't hear good things about the Sleeves of AEBS but I got no personal experience. I prefered Darton coz it is a well proven company about the sleeves.

I beleive with the AEBS kit, they have to grind away some of the block on the inside to allow for the longer stroke. Not a good idea in my opinion!

The AEBS has been done on Zmotoring.com by a member and had nothing but problems. It also took AEBS 7 months to complete.

The stroker will take a serious EMS to tune that thing. I remember reading some guy on here that had the stroker and was having problems tuning it. He had like $50K just in the motor.

What is your power goal? I think the stoker would be overkill with your TN ST unless you upgrade the turbo.

Performance Motorsports is coming out with shortblocks based on there 1400 hp street pro car. Darton sleeved Machined / Stock Crank balanced and journaled, Corrillo H Beam (Car Bolt) / CP Piston Package / 1/2 ARP Main And Head Studs... This bottom end is completely Race Proven up to 1400!

The sleeves are machined by Vinny and his Machinest. The Pistons are to his Spec as well.

If you are interested, let me know I can get you a turnaround time...

He also has cnc heads coming out. The cnc heads are mapped directly off the pro car.

+1 I would not seriously look into the 4.3 stroker... It is not race proven @ all... Nothing but a tuning nightmare from what I herd.... You will sacrafice RPM to go this rought.

??? How fast do you want to go ??? The fastest VQ is a 3.5 over 200mph...

Well first my goal was to get around 400hp.. Im already there and bored with it already.. Now im kinda at the point where i just wanna make my car as fast as you can.. I know my turbo now isnt gonna make much more over 500hp. But since i have a hole in my block i wanna build it ready for 1000+hp safest and smartest

If you want 1000hp I think you went with the wrong turbo kit. Also 1000hp is expensive, not streetable. and be nothing but problems. Most people dont realize how much HP that really is.

Want more power, eh? It's gonna take cubic inches and/or cubic dollars, and your investment will probably grow geometrically with every additional HP you gain. Where does it all end? Pick a realistic goal and stop when you get there. Boredom could be a very cost-effective alternative to higher HP...

I am looking forward to seeing what Mazzoo's Z is putting down when he finishes. IIRC, he is getting the AEBS stroker kit as well as the SFR 60-1 TT kit! There is a post about it going right now. I just read about it this past week. It should be a beast.

Sorry for the hijack!!

Well he definitely has the traction to back it up. What's he running in the rear, like 345 tires or something?

The AEBS stroker kit has given the few that have installed it...nothing but trouble. You could do a Darton sleeved block, and run 99mm pistons for roughly 3.8L displacement. Displacement is the not the magic bullet for safe power. It does help, but the important thing is to have a properly speced and assembled long AND short block, with the right cam choice, valve train components, and of course tuning and fuel requirments. It sounds like you want to overbuild the shortblock, and them come back later and add the other necessities to get you to 1000whp (which nobody has done on a street driven 350Z yet). Moving from a 600whp to a 1000whp will more than double your expenditure, as EVERYTHING in your car must be upgraded to bullet-proof levels.....the list is very exhaustive.

What are you talking about? The rod to stroke ratio in a VQ35DE is 1.77:1 that's nearly perfect. Do you know what consists of a failure of revving a 1.77:1 engine to 8500RPM? it's not high piston speeds, because the piston speeds arent that high. It's stock rod bolts. Stock rod bolts tend to stretch when they are over-revved, causing.. yep you guessed it spun rod bearings. an AEBS stroker kit lowers the rod to stroke ratio and makes the engine harder to rev safely.

im not necessarily going for 1000hp.. i was just stating that the block SPR makes is good for up to 1000+hp.. I dont think i will ever achieve that. I would like to one day get my car into a 10sec 1/4 mile.. So im not sure how much HP im gonna need for that. im guessing around 7-800? Well after hearing bad news about the 4.2liter stroker kit i think im gonna go with this block:

PAuter Rods
Arias Extreme Duty pistons
Darton Sleeves
ARp Head Studs and main studs
multi-layer metal headgasket
Clevite or nissan bearings
w/ a knife edge, perp drilled crank <--pros/cons?

What do you guys think about that?

I suggest getting something that is used and proven. Alot of people speculate and say "these internals, these parts, this combonation is only good for x amount of hp" however the people speculating have never tried the combination. I personally have seen quite a few VQ30s, VQ35s in the 600-700WHP range. And that was with standard nissan sleeves, with overbored sleeves, and overbored pistons. I would suggest Darton Sleeves, pauter rods, and a custom piston.

However getting to the 1000hp mark is alot trickier then just picking internals, you have to figure out a fuel system, then you have to figure out how you'll pu the power to the ground (reliably) etc.

+1.... PM's car rev's out to 10k with the same exact bore and stroke... My motor will be tunned between a modest 7.5-8k...

Looks like you are looking for an engine to last and give you good power. A motor with strong cycle life... that is good... Everyone has there oppinion about parts. I will quote one of the best import race engine builders, if not the best.... Vinny Ten " In 20 years he has never had a corrillo H beam rod fail" Not once! He has used a set of H beam rods for a full season in his Record Breaking Pro OutLaw Supra... Some may not know who "Vinny Ten" is, if you don't, Google him...

The cost of this project is going to be pretty high, for the difference of 300.00 I would go with something that not only can take anything you give it. but also have the long cycle life you are looking for. Corrillo H-Beam / Car bolt...
