ok so everyone knows that there isnt much we can do for the 2001-2004 3.3 non s/c frontiers. intake, exhaust, thermostat, fuel pressure regulator and maybe a few other small horsepower modifications. but i THINK i came across a setup.

now i called the guys in the parts dept. at my local nissan dealer and had them fax pictures of a 90-96 300zx Twin turbo engine and a 03 frontierv6 3.3 non s/c engine to where i could see/ compare part numbers.

the exhaust/turbo manifold (call it what you want) is exactly the same as on the 03 non s/c frontier. part number and all. the manifold on the frontier has the pre-cat where the 300zx has the actual turbo. the gasket part numbers even match up. (you see what im getting at)

now correct me if im wrong but the stock turbos on the 300zx are fairly small. a little work  ( i hate to say  "CUSTOM" because its such a overused word ) from a machine shop. some pipe routing for the turbos and intercooler (which is not as much of a big deal as it seems) and reprogramming on the ecm.  and you have a twin turbo kit for the frontiers. 

now, i know it is nowhere near this easy but, we own a fully functional 8 bay automotive shop so clean you can eat off my oil drains. ---- dont mean to sound like a cocky prick but i just want to let you guys know that i have access to being able to lift my truck up, take it apart and look around.

so i ordered an exhaust manifold from the 300zxTT. and i plan on lifting the truck, disassembling (with pics) and test fitting when i do my 60.000 mile service some time this week. this way i can actually see if this is gonna work and let you guys know whats going on.

I would order some lower compression pistons, especially if your going to add a twin turbo.  Check out www.importperformanceparts.net  They have engine kits, if not, they'll make a set of pistons for a good price. 

There is some subtle difference between the VG30DETT block and a VG33E.  Also, help it breath better by regrinding or getting some JWT stage 2 cams.

ok have to be short here ill come back and explain later.

check it out. read around.

well 4 wheeling would be out of the question. heavy fourwheeling at least.

this kit is mainly for towing, trucks with over sized tires, and for smoking turbo diesels.

they do not make a kit for the frontier. i have been back in forth trading e-mails with one of the employees and we have figured out ( luckily one of our employees has a 04 tacoma 4x4 and we lifted my truck and his truck to compare) that the tacoma kit (with obvious modification) will fit..

granted i will have to make a setup for my mass air flow sensor and air intake sensor and have a few intake pipes made up. but other than that and tuning ----> the stock tacoma 3.4 v6 pumped out 354 horses.

again. common sense tells you no way this would be a daily driver but that tacoma was at i think 14 psi and running methanol.

these kits do there work under the 3000 rpm range and are safely run around 5psi. so all in all you  end up with a 280 -300 horse daily driveable nasty sounding frontier.

as an extention to my previous post i was perusing the STS site further and saw some interesting clips of the tacoma running in the mud and water with their snorkle attachment which raises the filter element even higher and out of the way, now granted they weren't going into deep water but the links were fairly intresting to see that they could splash that much with the intake back there and not phase it it seems. One question I would ask the manufacturer is if you could add the AEM dryflow filter or other after market filter elements to the system, because i have been interested in that..and it seems to flow very well as well as filter better than any other element i've seen so far and it doesn't require oil...also note that the tacoma there in the vid clips sounds not too bad and that is even without a muffler it stated on the site, so if you wanted to mellow out the tone even more you could put a small muffler or resonator aft of the turbo and tone it down even more, but they also show dyno numbers for diff boost, 5 psi and 12 psi respectively, then in their dyno chart, they compare their set up running at 4psi to a TRD supercharged tacoma at 6psi and claim it got 15% more HP and 23% more torque, i must say i'm intrigued at the least....

anywho their 5psi numbers seemed very impressive for that 3.4 in the tacoma...like 248HP and 270 something ft/lbs, i believe their 3.4L stock was around 190 HP and 220 ft/lbs...

however to ask a further question of what kcidmil was suggesting, i'm not sure a cam would be totally necessary or warranted except for increased exchaust opening, no? their site talks about actually going smaller with cam rather than bigger...

also what seemed interesting and curious to be is how they are pumping oil to the turbo and intake temperatures being lower due to running cooler through the intake pipe back up to the intake manifold

i just noticed on their site as well redracoon...that they have a universal application, not a kit, so you could probably get some stainless tubing made and coated and then mount that turbo anywhere you wanted rather than using the tacoma kit, although it would probably be pretty close as you stated since you did the investigating. again if you do it...let us know and see pics/vids/sound clips, i'd definitely be interested in that cause i dig my truck but who wouldn't want a little more power :) yeah i wouldn't run above 4-5 psi with it either just something that is usable for the DD especially if you do a lot of towing, having that extra torque and power would be a plus

i think my personal choice is that i'd put a resonator aft of the turbo or something to tone down the noise just a tiny bit but that's just me

If gets lower compression pistons... he'll need a bigger cam. 

They suggest smaller cams on the site because they don't say anything about a lower C/R pistion.  In fact... they suggest the smaller cam because with a stock piston... that much air being forced into the piston for so long, just might blow a seal, or cause blow-by. 

With the lower C/R piston... there's more volume to fill, and with a stock cam, it might not fill enough, causing a lean mixture, resulting in a quicker carbon build up.
