As the new year approaches, I hope to soon getting to work on the down season. Figured I could keep some progress reports here as i start heading into bigger and better things.

First on how it started. I believe I am one of the first people running around on a vq35 swapped S-Chassis that is running strictly on factory ECM/engine harness without the Z/G body harness.

Old article from when i finished up the original swap.

This is mostly about my motor build, so I will keep most of this page about that unless anyone cares to speak otherwise.

Around this time in winter of 2013/2014, i found myself with everything I needed to slap a Vortech onto the car.

I was running a 100% stock low milage DE motor.


Headers and an exhaust was something I wanted to focus on doing once and right to support the extra flow






The intercooler and piping was 3" one off with a one piece MAF tube. Other then that, factory intake plenum and setup.
Only other mods to the motor was deleting all the extra cooling items and running a large Setrab oil cooler off a Mocal plate.





Took it down to Jon @Z1 and made 447/401 tuned on uprev.
This is running a 2.87" pulley on a V3 SCi making 10.5 psi.



I was honestly impressed and exceeded exceptions, but i knew it was only a matter of time...



Which brings me to where im at now with the current motor build and the quest for 550!

 

So the build sheet for the block is as followed

It is currently with Forged Performance getting it machine work done

Aries 9.0:1 Extreme Duty Rods .20 over
Manley H-Beam rods (still throwing the idea around upgrading to the turbotuff I beams)
HR Coolant mod with HR Head Gaskets
L19 headstuds
ARP Mains
ACL Bearings
Revup Oil Pump

Fuel Setup:
Have a full 6an return setup on an Aeromotive AFPR
Currently being pushed by a walbro 255 but should be upgrading to a 400 walbro
Running 2014 R35 injectors 570cc. Will need more injectors most likely.

Cooling/Oil
-Coolant system is currently simplified to motor in, motor out, radiator with a swirl tank to keep it that way. Entertaining the idea of the pathfinder coolant mod before the new motor gets put back together
-Koyo Radiator
-30 row Setrab oil cooler
- With the new motor, an Accusump oil accumulator setup will be installed. Working out the details for that

Airflow:
The exhaust setup i have should be plenty sufficient.
1.5" primary headers to 2.5". 2.5-3" Y-pipe with a removable 30" canister muffler out the back.
The intake setup seems super efficient to me. Its a 4" core intercooler. Its obvious in the dyno sheet that i had horrible fall off after 6k RPM due to stock intake design. A Kinetix SSV arrived last week to remedy that issue.



So here is where i stand in my goal to go up 100 hp and tq with the new motor and looking for help to those in this territory.

A supercharger upgrade?

I am just about out room of spinning the V3 faster. Currently at a 2.87 pulley and stock jackshaft pulley's. How much more do i have to get out of a 2.62 pulley and/or a 34/28 pulley.

A v4 or V7 is not in the budget right now as fun as that may sound.

My original plan was to put 928 v+ billet impeller but they arent available for V3 units and i cant get a definitive reason why they are different. From what i can gather, the impeller profile is different in the housing compared to a v1/v2. If this is true, can i get a compressor cover and the upgraded impeller and be good? Im contacting 928 soon.

If that isnt possible, ill be looking to downgrade (?) to a v1 or v2 and then upgrade to a t-trim or the 928 impeller, but new unit is not in the budget.

Also been throwing around the idea with some cams. Not sure which is gonna get me a bigger bang, upgrading cams or upgrading supercharger. Will either get me to 550 or should i really be looking into both.

Any other crazy ideas to push me over. corn, meth, race fuel? Not sure how uprev can handle that.

 

I always wanted to throw a blower on my old 00 and see what it would do, that's if I still had it...

 

Why not go higher on CR?

Gl with the build.

 

I was 100% sold on the Aries ED pistons and I was looking for something a little more off the shelf. Turns out that all the Extreme Duty pistons are made to order anyways. Sorta wish i could have bumped it up a bit but I dont think i would have gone high comp. The E85 in my area is very inconsistent and since I'm still planning on sticking with Osirus Uprev, I have no way of monitoring the ethanol content on the fly. I definitely would be doing so if I was in a position to get a quality standalone, but I should be able to hit my goals safely on this setup.

In other news, been discussing it with a few people over the New Years and it looks like I should be putting a Ti Trim on my V3. Just have to confirm its still possible with Vortech today. Thats 1400cfm compared to the 1050cfm I currently have.

 

Send off for the SI impeller upgrade. I was able to reach 550 @17psi on the fluid dampr crank pulley and 2.87 pulley. I have a build thread on here. Also going to a v2 wouldn't be a downgrade. It would change your oil supply from being self contained to being ran off the engine oil which I preferred. Can add in a large oil cooler and keep temps down in the blower. Also a plus when changing engine oil, you're also changing blower oil at same time..

I would look into 1000ID injectors and twin 255s or something similar.

 

Subbed

 

awesome build. subbing and staying tuned. im currently drifting a vortech ttrim with custom piping. doing a motor build as well for next season

 

Yo bro. I know you got the $

Is that in reference to the finger nails. That's just a lady friend of mine.

 

Very important piece of Info here... This is what is stopping me from going E85 in NJ. While we have some stations close by consistency is hard with 4 seasons.

 

So a bit of an update. Time has been ticking buy way too fast and I'm super behind schedule on the build.

I've got the short block back from forged and in the mean time I decided to go do a bit more chassis prep. Time and money have been tight and has set me back a bit.

Plan once chassis prep is finished is to run the same v3 sci and r35 injectors for motor break in until I can get it dyno tuned again. There is so much changing right now, I didn't want injectors and a bigger SC to be a factor in initial break in.

Once I'm ready, I'm 95% I'm gonna end up with a bill it YSi after all. My goal is now set at 600hp/550tq. Still undecided about cams right now. It would be nice to spend that grand somewhere else and I think I could hit my goal on stock cams. Opinions?

New upgrades to the build include:
Kinetix velocity with a 70mm TB
Full Accusump setup
Fuel surge tank supplied by a drop in walbro 400 and pushed out with an 044.
Redoing the lines at the motor to split to a dual feed and dual return to the regulator. Should provide more consistency. ID1000s too.
I've just about finished a rear mount radiator setup which is gonna free up a lot of room to allow for an even bigger IC. That will likely be done with the SC upgrade though.
Uprev had had talks about a flex fuel sensor integration, hopefully it's something that could be integrated with VQ swaps. All their new 2 step stuff requires BCM and such that I don't have/need.
Going big with heat protection this round for both driver comfort and engine safety. Wraps, tape, sprays. It needs it.

Really just killing me missing all this seat time. Need to get out there ASAP and start bangin doors!

 

If you had just bought my car from the get go, and swapped it all over probably would have cost you less lol.

No but cams would be worth it. You're gonna need everything you can get for the blower. I would do it.

A turbo you can make 700whp with stock heads, but with a blower, pretty much everyone making 600 has cams, and an intake mani. I would just get an uprev intake manifold (I paid like 75 for mine, they give you shorter runners so more power up top).

Good luck making that torque on a vortech though lmao. You're gonna need it.

 

This is sick. Gatta love when people keep the S chassin Nissan.


too many LS, and JZ swaps now.


GL hope it all works out..


Awesome nails btw
