10,000rpm, Long rod, VVTi, Turbo 4AGE Hilux - dyno tested

[@Garage4age]

I lied, its limited 9900rpm, not 10k. Other news, I have added a db sound meter to the dyno wall. so you all can see how deaf I'm going. Also have a new mic for the camera, which was being used for the dyno pulls and the clips at the end. If you didn't get past the graphs at the end you probably should.. So yeah things should sound a little closer to what the actually sound like. As always, if you missed the engine spec's they are in the description. Giz a like and all that weird stuff that everyone begs for, so i can afford to put the rods back in my block when they fly out.

What are the advantages of running the itbs in a turbo setup instead of just a single throttle body? And thanks for all the great videos, really useful information

[@Garage4age]

Hey, thanks for the donation. Mostly so the engine runs nicer at low rpm and idle. With a big plenum single throttle intake and or bigger cams, engine will stall out easier and not run down to as lower rpm. ITB's will run a lot better down there since plenum is on the other side of the throttles. An engine with bigger cams will run nicer with itb's than a single plenum regardless of plenum size or if its na or turbo.

[@ae86racer007]

Thanks for doing all this awesome research! I currently have a 4AGZE, similar to your old engine minus the ported head and with a big SC14 setup. I am approaching the crossroad of switching to turbo. I was thinking about a set of Kelford Turbo (HV) cams, 1SZ solid lifters, appropriate springs and then was heading down the route of a G25 (well PSR version) to try and get some response as I a really enjoy the instant torque hit of the SC14. How big is the turbine on your gtx2860? I'm probably also going to employ an antilag strategy as my application is an offroad buggy....which is why the instant response is so addictive. For the sake of information.....200kW is probably more than enough in a small single seater buggy between trees 😅 Interesting to see you had been pushing the 4AGZE rods and standard cams so far. Do you have a video detailing the porting and modified headwork somewhere?

[@Garage4age]

gen 2 gtx2860 is still really good match for low - mid 200kw at wheels. have tuned a pulsar g25 4agze engine, came on around 500rpm later than my old engine, but it did have some aftermarket cams, so results may vary. The g25 would be my next step, but would run the 2860 if dont want to go past 250kw. I probably wouldn't even bother with cams if your goal is around 200kw, a stock smallport ze with do that no problem, but will take more boost. around 18psi on a nice turbo manifold and intercooler setup, with stock head and stock na inlet manifold. done one not too long ago with same turbo as im running. cams can actually make the turbo come on later if you go too big. no vids on the head work sorry, the head on it was quite aggressively ported, probably almost too much for stock valve head tbh. was a hand me down from my na engine before i went to a big valve head. something the 10 year ago me did.. the one on the new engine is a bigport head and was modified not to lose power off the bottom. but yeh not as good as the other one up top

@@Garage4age interesting! thanks for the tips. I just figured G series was the new hotness, but good to have some real world experience. Any idea how big the cams were on the PSR G series thing?

Yeah all the numbers are at the wheels. Also running it up in 3rd gear, which usually shows less power than the 1:1 gear in rwd box. 4th would be almost 300kph due the big wheels and rpm, even with 4.88 diffs. which is way to fast for the dyno let alone the driveshaft.

I caution against reving this past 9 grand with the stock crank they start flexing and the rold bolts You WILL break them. especially with long rods they will survive a few dozen pulls to 10 grand but really you need to work on the bottom end if you want to rev there. also more boost there is a guy making 600hp out of 4age in his pikes peak car

[@Garage4age]

The long rods will make it easier on rotating assembly, not worse. thats the whole point. less side loading and vibration, which is a bad day for the bottom end. As per the video I'm not chasing big power. just wide powerband. If i wanted big power, the combo of parts would be different

[@benheynen2705]

Please recover all the torque beyond the current peak by turning up the boost. You are moving past your knock limit rpm and assuming you have the fuel there is no reason to limit it to a number. Flat line the torque so you stay in the drive line limits.

[@Garage4age]

Hey. Yeah that would be the plan if wanted more power. But it already has more than enough to do what it needs to do. Rolling over at the end will stop it going into the limiter as hard in mud holes and the likes

I should be able to run a bit bigger exhaust cam (have nothing in between here to try). but running the 278 exhaust cam out of this 284/278 set kills the boost threshold by about 1000rpm, for a bit more top end. which is a no go in this thing.

60 is the max travel of pulley, is setup to stop at minimum piston to valve clearance.

Few reasons. Had that cam hanging around already setup for the vvti. using the exhaust cam from the same set makes the turbo come on 1000rpm later, but does make a bit more up top. I dont have anything smaller hanging around to try and is probably a better combo. but this works well for the hilux. As with the vvti on the inlet and small exhaust cam, get factory like idle, hard to stall out and the massive powerband. all good stuff for 4wding. Almost everything on this engine is recycled from other projects, so some things are a compromise

[@Fix_It_Again_Tony]

@@Garage4age That's interesting. Thanks for responding. Having more torque lower in the RPM range is definitely better for the offroading I do than peak power numbers at high RPM. Is it overlap that causes the turbo to come on later? Do you think you'd see benefits from a bigger intake cam without the turbo? I have a Nissan D40 with the VQ40 and it has variable timing on the intake cam. I am trying to figure out if a bigger cam would be beneficial. I am concerned about shifting the powerband to the right and losing low end torque. I'm in the process of swapping to a solid axle in the front and will be running 37" tires. The purpose of the truck is offroading, but it will be street driven to the trails. My current thought is to just leave it alone, but I'd love to her your opinion. It will be NA, no turbo or supercharger.

@@Fix_It_Again_Tony Take a look at this vid Its basically the same engine in NA form with the same cam combo, comparing against stock cams both sides and big cams both sides kzbin.info/www/bejne/Y3rRp2SKoKaBotU A good part of how well it pulls off the bottom with big cams is the exhaust setup. Which is pretty well dialed on the na setup. the turbo essentially destroys all of that. since is creating pressure on the exhaust side. So yeah results will obviously vary from setup to setup and different engines. but just changing to a bigger inlet cam with the vvti to make it run nice would be a safe bet

Yeah easy, long as its in good condition with good tune. the "old engine" in this video is just an 8.9ze bottom end. has arp rod bolts, but otherwise stock parts.

Thanks for the reply

I have haltech 1500 would like to use it on my so 4agze twincharge or turbo . What would you go with?

[@astromarky123]

looking decent! cant wait to see it spitting mud everywhere again if you take the cameras out for some bush bashing

[@Dongaz]

Nothing like a 4a slappin 9.9k limit at 129dB. ooooftt That currawong knew to get out of dodge.

Old engine had more stroke as i undrestand and was better mid range which is logical. Vvti band aid the low rpm but no replcament for displacement. What is thr reason for the destroke?

[@Garage4age]

they are both 1600cc. old engine is a factory 1600cc bottom end, new has taller block but longer rods, same crank. more reliable at high rpm. The difference is in the heads, old engine had newer design smallport head that had been heavily ported, from one of my na builds. new engine has older design bigport head. if swapped the old head onto new engine would make more power. but already does what it needs to. old engine/head had more midrange power due to where the cam timing was set, if it had cam timing adjusted or vvti would make more power up top also. The new engine is mostly made of 2nd hand parts and leftovers from other engines and projects btw

[@abdullaalameri90]

@Garage4age very interesting,I take back my comment. Any chance of flowing the two heads. Is old design bigger port really flowing more than newer design small port. What about valve sizes and throat %?

[@Garage4age]

@@abdullaalameri90 The big port and smallport names are kinda misleading. its just the port entry on the the "bigport head that is actually bigger, which what seems to be designed around the toyota tvis system. further down the port the bigport head is smaller than the smallport head. both are the same on exhaust side. Both can be modified to make pretty much the same power. In this case its more the fact that the smallport head on the old engine has had more aggressive work done to it. They both are modified and make more power than stock heads. The bigport head was originally modified with the aim of not loosing any bottom end power and gaining top end. which i did, can be seen in one of my earlier vids.

I never ask but i know back then you use 47mm oversized blktop itb but what itb did you use now if those plate are 52mm still blktop oversized again ??

the 52's are bmw throttles

@@sachadohc2912 they have a separate external dbw module. that commonly breaks and is expensive. easy to convert to cable. port spacing is too big for 4age though, so have to modify them.

Which vvti pulley do you use? Is it very difficult to adapt? What computer do you control it with? the pulley on my 20v is dying

[@Garage4age]

Yeah very. its a 2jz pulley. runs an old link ecu. I would just find another 20v pulley,
