Nefarious

im trying to figure out a way to run the vg33e intake manifold which already has a better design (more flow, less turbulence zones) and a bigger throttle body (around 5-6mm larger in diameter). This should help immensely with a truck that already has headers/exhaust done and needs more intake flow. Ill be flashing my truck with an M30 factory tune (which already uses the N60 maf) and incorporating the 90mm N60 maf sensor. The combination of the large maf, larger tb, better flowing intake mani, headers and exhaust should make a massive difference to any vg30. Although I'm doing these mods to a vg33e so my results may be a little more prononounced; although they should be similar... The M30 tune will be enough to get me started with the N60 maf and then from there I can edit the fuel and timing maps for optimum performance and economy but at the expense of (most likely) slightly higher octane fuel. I usually run 87 so 89 may be required after the performance tune. Although fuel mileage should improve as well as power. In my 240sx I have gained a noticeable amount of power from stock and gone from 26mpg to 30mpg with just a K&N drop in filter, 3" exhaust system and a tune (Nismotronic SA). I'm hoping for similar results from my pathy!!! I do not expect as significant of a fuel mileage increase with all the extra weight I carry though Even a couple mpg will be worth it for me! Eventual goal with the pathy is around 200-210 hp and 220-230 lb ft torque and an average of 23mpg. I think it is do-able.

Oh sorry, misread there. And thats interesting ....I wonder if its a round tooth timing belt thing then.

vg30e has brass coloured valve covers, vg33e has the black covers...

or you could do a vg33e swap and leave your gears alone. that's what i did. i have more power than stock and im running really heavy 33x12.5s. my highway rpms dropped from around 2500 to around 1800 at 105 km/h down the highway. highway mileage actually improved, city is a little worse. i did my whole vg33e swap for about 300$. just something to think about.

I did the rad support on my 300zx (z32) which is way harder to do. I had about 80 spot wells to drill and re-weld back together. The pathfinder is a LOT easier. It's not a unibody so its not an integral part of the frame/suspension and there's only around 20-25 spot wells holding the pathfinder rad support on. It's also square so its very easy to line everything up again after. Just go to the junkyard, spend a few hours pulling one from a donor truck. Bring your drill and some good metal drill bits. There is a proper sheet metal spot weld drill bit u can use to only drill half way through the spot weld which makes welding the new one on a breeze but i just drilled them out and fill-welded the holes shut and ground them smooth again. I'll try and find the thread I made for my z32 it should at least give u an idea.

Yeah I own a z32 man, they are great cars. So much fun to drive and they still turn heads!

that build is sweet but its a vg30e-tt not a vg30dett, dual overhead cam vg. It has a lot more power stock than the single but has a lot more complexity and things to go wrong. it is also physically much larger due to the intake manifold design. (i own a 1990 vg30de 300zx and a 1993 vg33e pathfinder so I have both side by side to compare) they are both amazing motors but if I had the full twin turbo setup including low KM engine I would swap the whole thing in, dual cam engine and all. You could use the turbos off that engine and make a twin turbo vg30e but it wouldnt have as much power, as easilly anyways. either way is going to be quite custom and involve a lot of work, probably about an equal amount honestly so that is pretty much a wash. vg30dett with just simple bolt ons will make well over 400whp and hold that all day long on a completely stock block/heads. The vg30e's 13 head bolts does make a difference to hold boost but it has a much weaker crank than the vg30dett so its your call. a VG33e-tt would be pretty epic though. It has a stronger crank and better flow, it still wont make the power or revs of the dett but it will have enough! The VTC of the VG30DETT actually does increase low end torque substantially while maintaining high rpm power as well. It is also a more efficient engine. My z32 gets 28mpg in a 3400lb car. I would swap the whole thing in if it was me though!

U can do the full swap if u have both vehicles. It will fit with a 3" body lift. U have to take the two transmissions apart as well I believe to swap the bellhousing to run the 4wd trans with the vg30dett engine

I have run the obx headers for 2 years now and I love them but u have to make a custom y pipe. I wouldnt run 2 separate mufflers and no pipe work like u suggested. You want the pipes to meet to balance the exhaust pulses and increase the systems efficiency. Just go through and make a y pipe if u do get them. I had zero experience building exhaust and had just started hobby welding at that point and I made a y pipe and full custom exhaust in 2 days. I couldnt see a pro shop charging much if I can handle it with a 110 volt arc welder and a 4.5" grinder.

it will totally depend on the offset, width, and how much you want to trim. I am running 33x12.5 tires on 15x10 rims with a VERY negative offset. because the offset is so negative I had a lot of clearancing to do even with about a 3+4 lift (around 7" total right now). i have trimmed stock fender flares an the tires still stick out about 3-4 inches out each side. I could easily run 35x12.5 if i went less aggressive with the offset, and I plan on doing so on my next set of tires. I had to clearance and trim the pinch seam on the rear of the front fender wells and then hammered back some of the sheet metal and welded it back together further back and undercoated it. Completely unnoticeable from the inside of the truck and increases the front tire clearance massively through corners. I also cut the whole front of the fender off in front of the tire along the line with the bottom of the corner light (to make a wrap around hi-clearance custom bumper later down the road). I also trimmed the rear but not so much as it stuffs the 33s as is with just some trimming in the bottom corners (front and rear) of the rear fender. Very little was taken off here. I also run 28.8" tire steering stops for absolute maximum steering angle and even when bumping around on the trails I NEVER rub anymore. Hope that helps

oh wow. thats like 46 degrees celsius!! I COULD NOT HANDLE THAT. I basically die after 32-33. Literally hiding inside the shop on days like that. I give kudos to anyone who can handle that heat and actually do something in a day. LOL. It got to around 32 and so well I ended up hiding in the shop doing a service on my 240sx. She needed some love too. lol

I would pull the z24 and install a ka24de out of a frontier if it was me and I already had to pull the engine for seals anyway... I have a ka24de in my 240sx and its the best and most reliable engine I have ever owned. Only thing more reliable than my pathy is my 240. You will get a significant power increase and they can be had for peanuts. Around here anyways...139$ on sale at pick a part. Then u can do all the work on the new motor outside the truck and once its all ready and resealed just swap it in and run the ka24 ecu/engine harness. Then your down time is cut to a minimum as well. I know its work but that is what I would do. Just my 2 cents. I have always wanted a 2 door 4x4 pathy with a ka24de!

I gained a noticeable increase in power. Mainly because they don't need to turn on often to maintain the pathys temperature. I have mine wired with an adjustable thermostat switch. I have never overheated and honestly the fan doesn't kick on very often. Just going up steep hills at slow speed offroad or stop and go traffic in the summer. Saving quite a bit of mechanical energy by taking the stock mech fan off and running an electric. Unless u have it wired to run all the time then I would think the difference is negligible. With a thermostatic fan controller there is DEFINITELY a useable power increase. Highway or backroads and it stays off pretty much 100% of the time. A larger rad would help this effect too. I used to run a 3" thick alum rad in my 240sx and NO cooling fan at all. Temp never even moved a hair even in city stop and go driving in 30-40 degrees celsius

Nope, Mr.510 crank adapter is being used for her truck this time. Her truck is her daily driver so we need to have it off the road as short as possible. Vg33e full short block, heads, crank, oil pump, filter housing, etc... just the accessories and manifolds will be from the vg30. Oh and the vg30e water pump and left side valve cover. Should go in nearly like stock with only a few minor modifications to fit the vg30e accessories but with all the benefits of the vg33 like the stronger crank, better oil pump and filter location, round tooth timing setup, right side valve cover oil filler extension. We are painting everything too. I will be a little jealous! I never made my vg33e half as pretty as hers, ah love.... lol.... I'll get some pics of the progress today. I was too tired after working all day yesterday I just wanted to flop and crack a brewsky lol.

A slammed 2wd hardbody will get 30mpg with a vg30e for sure.

Finished prepping and laid the 2 base coats on my lady's vg33e block. Good old gloss black. Looks amazing so far. We will wait a couple days and then finish the coats and start putting everything back together with the vg30e externals. Everything is coming together! And for my truck I picked up some steel to patch a small rust hole in my frame. The rest is mint, just one tiny spot has a hole...weird spot but ill fix it next weekend. My truck is almost ready for the trails again and my gfs us almost ready for her vg33e swap. This will be a fun summer!!!

BTW they are right these trucks do have a decent cold air intake from the factory. The intake tubing isn't the problem. It's great for stock or a little higher power but the real limitations are the maf sensor, and throttle body. Once you open up all the exhaust pipes and get a set of cams the maf/throttle body do become a serious restriction. The vg33e intake manifold also flows substantially better. I'll be integrating all these together and get a dyno day in after university is done for the year and i can afford it again!

What was mentioned above ^ . Also check your electrical grounds, and I would suggest checking your maf plug connector and testing your maf. There is a procedure in the fsm if you have a multi meter.

Racing is not just for the young! I guess my love of fast turbo cars just rubs off in the 4x4 world as well..! And you are correct. Most of BC has no smog laws and the only place that does (lower mainland, where I live) is getting rid of it by the end of 2014. I get a 2 year pass each time so I am now good until the aircare program ends for passenger vehicles. Now is when it gets really fun. I'll definitely post updates on the ecu tuning once the rest of my components come in. Specialty tools have all arived I'm just waiting on some EEPROMs and a programmer

No worries everyone! I am just waiting on parts from over seas and the progress will continue!! Should have an update within a week!

BTW my pathy already owns ANY 90s Toyota in town. Many runners and jeeps from the 90s have tried, I have won every time!

I just raced my gfs 93 manual vg30e pathy with no lift and stock tires. My 93 auto vg33e pathy with intake exhaust headers and electric fans and 7 inch lift on 33x12.5 tires on 15x10 steel rims (wheels are literally 85lbs each with tires) and I stop won from launch all the way through to 110 km/h. Power can be had in these trucks! Once I finish my tune and intake work it will be even happier

Vg33e swap, headers, exhaust, intake, electric fan, <~ I have already done.(and its noticeably faster) Vg30e cams, n60 maxima maf, vg33e intake manifold, ecu tune. <~ is next on the list. That is my plan and I'm aiming for over 210 at the crank and over 225 lb ft torque once the tune is finished. Won't be a race truck but it WILL be fun.

I didn't do anything today... I am still waiting for parts in the mail!! Should be able to start the ECU tuning soon though.

sick truck man. that thing is beast.
