Hi guys, Haven't been on in awhile but thought I would bring everyone up to speed on our Z. Last year was a tough year for our car. Long story short we decided to do a big build for this year. Every part on the build will be brand new(bolts, heads, block, sprockets, covers, etc.) Eric( my parts mgr) has a great relationship with the guys at injected and it made sense to have them do this build for us. As the title says it will be a 3.9 stroker sleeved with BC and injected performance components. Our hope is to run 10.0-10.2 without nitrous at the same (19-21 pounds) or less boost. I will have Eric update with additional info if you guys are interested or if Hal or any of the injected crew sees this thread feel free to ad more info as the build progresses. Jason

 

nice 1/4 et!!!

 

A lot of people have had problems with sleaved VQ motors. You might want to research the subject here in the forum. Also, it is my understanding that sleaved motors run hotter, which might not be a problem if you are only using the car to run 1/4 mi.

If you plan on running any road courses or pushing it hard on the street, I would definitely recommend that you do the research and re-consider. Maybe Injected Performance can do a 3.8L or 4.0L non-sleeved motor for you. GTM has a 87 mm crank that will get you to 3.8L, and a 90 mm crank that will get you to 4.0L. For the 90mm crank, I think you need to machine the block a bit to get adequate clearence.

 

IMO, the issues surrounding sleeved VQs stems from improper machining/installation - not from a design or functionality standpoint. When done correctly, sleeves WORK!

Bldrz, Good Luck with the 3.9L!

 

GTM did the installation for my sleevs and i dont have any problems with them !!

i did drive it hard on the street with 0 issues and my radiator was stock that time.

 

Thanks for the input from everyone. We did alot of research about sleeving the motor. That is why we chose injected. We were not comfortable with the machine shops installing the sleeves locally. As mentioned above when done correctly it should add strength and durability to our set-up. This car is primarily a drag car. Only street miles driven are when we take it to local shows. Thanks again for everyones comments, Jason

 

you can to 3.9 without sleeves. I know of a 4.0L, non-sleeved custom stroker that is out there.

 

We have not experienced any sleeve failures on our VQs in street or race cars, and are very confident in our sleeved motor packages. If this was a 500hp road race car, I would reconsider sleeving - but for a high horsepower engine that needs to repeatedly and consistently output serious power... sleeving is absolutely advised. Boulder has selected proven top of the line components including our stage 3 stroker and race ported head package.

Thanks Boulder Nissan for choosing us to partner with on your build, we are really excited to see this one through!

 

Looking forward to results...

 

IP, Pls..

 

Right now it would just be a bunch of Nissan boxes... boulder wanted everything new... every bolt, the block, heads etc. The block is currently being machined for sleeves, and the heads are being cut on as well

 

Pics of parts out of boxes FTW!!

 

We like pic's of boxes !!!

 

 

Hal, If you have the time could you post pics as the build progresses(sp?)? Thanks, Jason

 

Just got some pics from Injected. Here is the block and heads, Should have the motor back soon. We will keep you guys updated with how the build is coming once we have everything. Thanks

 

Awesome man!! We go way back with the low 10 second passes back to back. Im sure it will be a beast when you are done with it.


Get on some lower ground and show us whats up

 

+1 ImportFaceOff in Bradenton Florida in October might be a good idea

 

That's sweet man!

 

Thanks everyone. I just got back in town. I am excited to get back in the store and get an update from Eric. I am really looking forward to getting our Z back together and running again.
