I am thinking of going with something like 9.0:1 pistons, Pauter rods, AEBS sleeves. Most of these pistons are custom made so the fact that we want different comp ratios shouldnt affect a group buy. What are some good piston manufactures? I can ask my tuner to order these or if you prefer, Crawfords.

If this built motor project does go through, i am aiming for 600 rwhp with just the ATI @ ~ 19psi, exhaust, cats, headers, and a high flow plenum.

I am just worried that daily driving this car will be a real crunch on fuel because we will be making close to 180 rwhp driving around at 3000 rpms in 6th gear at 80mph. Is there somethin available where we can bleed the compressed air back into the SC with some sort of BOV, kind of like a boost controller and a wastegate? If not, I might have to settle for swapping pulley's for daily and for weekends and saving at least 2 fuel/timming maps.

 

Yeah, I saw the shop but it wa empty at the time. Doug(I think that was his name) was repainting the floor while I was there. He drives a silver Evo. I saw their 500+ hp red Evo while I was there, well whats left of it. What kind of work have they done for you?

Yeah man Doug is the Tech. He is an awesome guy and also he knows what he is doing. His Evo8 is really nice car man and the red Evo is there too. I think 500 hp is too low for what that car can make. Is capable of more and it will do more also. He is also still waiting for the block to come back.

They did the installation of the TT's on my car with and excellent price, which included clutch and flywheel , exhaust, guages, emanage and other goodies. Right now my car is in the shop we are doing a fuel system plus a little bit of tunning. George and Doug have been great with me, they have been preety cool with me. Im telling you bro if your doing anything to your car from suspension up to turbo's they are the shop to do it at.

Anybody is welcome to check them out. I took my car to the nissan dealer and the head mechanic said that is one of the nicest and cleanest jobs he has ever seen.

why aebs sleeves. I am sure the stock sleeves can handle 700+ whp.

 

If you dont mind my being nosy, what did they charge for the TT install? I am not looking to go TT, but I do want to go with the Vortech SC in the future. I know the TT install is more, but I will kinda know what their TT install is compared to other TT installs. I am glad you mentioned something about these guys.

I like the idea of 9 to 1 comp ratio for this 16 psi set up....

Check out sgp racing for pistons also an engine rebuild should not be that difficult to get done locally i was quoated 18 labor hours for removal and reinstall of the engine as well as 11 hours for installation of rods, pistons, cams, head stud kit, and titanium valve spring retainers once the engine is out of the car.

Everyone i talked to about building up the VQ motor likes pauter for the rods.

The factory sleeves are cast iron and one shop here in boulder has bored them .20 over and they are confident they will handle 700 hp.

When your hp gets over 500 wou should seriously consider a racing main stud kit for your heads (sgp racing)

Too high of compression then you have to worry about detonation issues on pump gas... too low of comp then you will have a sluggish car untill 3500-4000 rpm when the sc starts building decent boost.

the quotes i recieved were from a local nissan dealer which has a performance division.

 

For those of you in ATL, there is an AutoX at the Gwinett Co Fair Grounds on Aug 15. You must pre-register. Ill be there. http://www.peachtreebmwcca.org/

Now we're getting somewhere....

I've read that the stock sleaves will handle up to 35psi of boost, and the aftermarket ones will go to 50psi. My goal of 16psi should allow me to keep the stock sleaves.

My opinion of the Vortech has changed drastically over the past few days, as it is NOT possible to raise the boost like you can with the Procharger. The Procharger will go all the way to 24psi with the right pulleys, and that isn't overspinning it. The Vortech, from what I understand, has very little headroom past 8psi. I thought I would be happy with 8psi, but I'm now thankful I got the Procharger and I wouldn't trade it for a tt, as the extra $4,000 in cost cannot be justified in my mind.

Pauter rods are what I'm looking at, so basically its just the pistons and camshafts that are left to worry about. I think I will also have a local place do the head work, with bigger valves, titanium springs and all that good stuff. My biggest concern is the engine swap and I am thinking I might let Infiniti do it, but I will have to get a price first.

So, we need to see how many people are truely interested in pistons and decide on a manufacturer.

Cool!

I really got the best price around and I shopped around. PM me and I tell you the price, but towards the price for the supercharger call George tomorrow and he will give you a quote is definitely going to be cheaper than my car and mine wasn't exepensive hit them up and let the m know you've been talking to me in the forum. I already mentioned it to Doug.

Finally people are seeing this. I have been trying to explain this fact about vortech for several weeks now

This is what I would like for my set up...
(I currently have a 5AT)

-Nismo cams
-Pauter Rods
-Aria pistons
-Stock compression

 

Good info in this thread, I was not sure about the factory sleaves.

I am looking to build out my engine in the next 6 months....I was thinking of running 9.5:1 and running a bit more boost.

Pauter rods and Arias pistons, I have heard that combination from so many people....its getting scary.

 

I just want to leave some room to grow if i end up upgrading the tranny, diff, and drive shaft. Im sure with head work, cams, the ATI can reach 750 rwhp with 3.5 liters.

 

Good luck getting traction at 750rwhp without doing some serious tubbing or something. But, bragging rights are always good too....

Arias pistons have been talked about a lot, and Pauter rods are 'the thing' to get. So, it looks like we are getting much closer.

 

here is a pic of the vq block you can see how nice and thick the factory sleeves look.

As far as bigger valves are concerned im not convinced this is necessary. After much discussion i ve been told several times that these heads are some of the best factory heads ever designed for a production vehicle.

They really will benefit from a cam which offers higher lift and longer duration like Jim Wolf Technology cams. This cam has been reccomended time and time again for FI vehicles.

 

Nice picture! I have heard that the two weakest parts of the engine are 1. the rods 2. the valves. I guess we'll have to do soem research and find out the failure rate of the valves in high power applications.

My engine would be sitting at sunbelt probably beside one of his IRL Infiniti Pro Series engines waiting on a low compression AEBS stroker kit and some turbo setup . . .on second thought It would have a work order on it with three words "Make it BULLITPROOF" ok maybe 5 words "Make it BULLITPROOF @ 22 psi" I would let them just take care of it all.

I have no idea . . .until I have the cash to do something like that i will keep trying to go for 300+ n/a power (which will still involve Sunbelt).

BTW, I think the modules will be here today!

 

Well, bulletproof would be nice, but maybe you could just get one of these?

Sounds like there are spares.

 

umm, a turbocharged v43 would make more hp and torque than an irl motor.

 

True, and I want one. However, the IRL motors are in existence. I have yet to hear of the so called "vq43dett" around. (<-- by the way, that is my yahoo email address too.)

 

I doubt the supercharger can reach those kind of numbers. Drifeshaft? You already have a lightweight driveshaft. I don't think that would be streetable. And axles, and suspension, and bracing for that kind of power.
