Well, we toyed w/the idea of going sleeved/forged this year, but decided to do another Vitara build instead and just step things up a bit from the old setup. We'll see how she holds up!

We are hoping for low 10's-high 9's at 142+mph this year. 500+whp.

We just got it up and running in basic NA form, all seems good. 19-20in/vac, idles perfectly. We performed the break-in and Dyno tuned it in NA form just for kicks, now it's time to build the turbo setup!

Here's a crappy phone pic of how she looks right now, things will be cleaned up and modified when we turbo it. I'll post the NA dyno charts tomorrow.

in for this....

 

Glad to see it running, looks like you finally got some time to work on it. I really hope it stays together long enough to break some more records!



BTW, it looks really lame NA.

 

Yes, it does look really lame!

I just figured I should put some pics in the post, maybe I should've just waited until it was finished!

 

Im stoked to see the turbo setup come together.. Shes lookin good...

 

 

Looks super clean!!! Cant wait to see the outcome!

 

Looks good cant wait to see it in person!

 

Looking good man. What did it out down NA??? Cant wait to see the turbo installed and new dyno..

kevron

 

teaser thread...9 seconds D16 on vitara's

Love the turbo choice!

 

dope. cant wait to see it.

 

Very clean. Can't wait to see results.

 

Good work guys, hopefully you wont be scrambling for parts at BOTI woodburn this year. But i must say, the dedication for the pit area rebuild was awesome. You guys do awesome work

 

haha that was pretty funny!!

 

oh i am sooo in for this!! i am on the verge of slapping together another vitara build myself...trying to find the lightest chassis i can and see what happens!

Good Luck James and The SpeedFactory!

 

haha looks pretty cool, i'm interested to see the upcomming numbers.

 

The turbo just arrived today! Here is a pic...

 

very pretty. nice turbo man. good luck with the build!

 

It seems like nice turbo single cams are popping up everywhere lately.

Cool project.

 

that snail is a beautttty

 

Thanks everyone!

As for the late night pit action, yeah, I hope not. It made for a memorable event though, and I'm very thankful for all the help/support from you guys down there.

So here's the NA results. 126whp/95tq.
We just ran it with a 3" short ram, stock exhaust manifold & stock cat mated to my 3" exhaust.

I was surprised at the output, I was only expecting 100-110whp.

Here it is overlaid with another NA vitara build I tuned for comparison.

The dotted line above was a standard rod (lower c/r) 75mm D16Z6 Vitara build that had all stock port head, cam, IM & TB, 3" short ram, stock exhuast manifold, high flow 300 cell metal core cat, and a Greddy SP exhaust. 112whp/100tq.

Although this will all change somewhat when forced induction is introduced, it's still interesting and educational to see this comparision.

I'm happy to see that this motor is showing it's high rpm superiority at 6000+rpm as that is where it will be run. Textbook example of how a large port, big cam, and large plenum/short runner IM compares to the stock parts that are designed for lowend/midrange. Power peaked at 7600rpm vs 6400rpm.

For reference, a 100% bone stock D16Z6 only makes 95whp/88tq on our dyno! All these tests were performed in 4th gear with a stock Z6 tranny.

 

More good news, 'Bisi has decided to help out and be a part of this build.

Thanks to Bisimoto Engineering for stepping up and providing us with a custom cam for this build!

Also a big thanks to our friends over at AdvancedStreetPerformance for the headwork!

 

Very Good build!

 

looks nice! I liked the other d16 that was the fastest stock sleeved in the us I believe?

I'm going there to get my ls vtec tuned in the next few weeks though

 

Thanks man!

We are just going to run this in my street EG again for now, same chassis as last year.

But we have another integra race chassis we are working on that this will be going into when it's done. It will be under 2000lbs w/driver, 1-piece frontend, fiberglass, lexan, wheelie bar, etc. I can't wait to put it in that chassis, it's going to FLY.
