Outstanding video, what a great project, thank you. The piston comparison was very informative. So many questions, I hope you can help with. Will you use the 2AZ-FE donut oil cooler or a separate cooler? Now, both the 1AZ-FE and 2-AZFE pistons you show are from before 2006, so these 2AZ-FE pistons are NOT the ones prone to blockage and oil burning. I have never seen a direct comparison of the piston design for 2AZ-FE from before the oil problem (2006). Did you get any special technical data from Toyota? After 2006 (or 2008?) Oil squirters were added to try to cool the pistons to help prevent the oil blockage problem. Also, the water jacket insert was an attempt to cool the exhaust side of the block, where as you show there is no oil drain that can aid in taking away heat. Is a better water pump called for? Clearly the 2AZ-FE is designed for the low end torque for easy daily driving in the larger vehicles. For the more average modder, is the 1AZ-FE a more sensible engine and a more likely donor for a square high revving engine suitable for boost?
Thanks for the info. Any possibility to compare post2006 2AZ cams to pre2006 2AZ? Which is better for a 1AZ to use ? Seems like the 1AZ is better built on the pistons for reliability and no balance shaft to deal with
3years on! Can i get a comment? My car blew out the 2az fe engine and am thinking of putting in the 1az fe engine as a whole. Question 1. Without altering anything, are the mounts similar? Will i change the transmission?
Can you answer a question for me? Does the 1azfe lower crankcase stiffener fit over the 2azfe crank and rotating assembly without colliding? Wondering if its feasable if you use that for balance shaft delete and go to the 1az oil pan with it?
Sure does fit. A few of the TC guys have gone this way in the states instead of using the 2az lower skirt and blocking off the oil feed for the balance shafts.
@@MODIFYUP hey thanks for that. Actual tested ideas are the best instead of what you read on random sources. Would help with crossmemeber clearance as you say. Maybe let you tilt it down a bit more.
Hello , thank you very much for doing this comparison . Wish to ask the 1AZ piston compression height & 2AZ piston compression height ? Both block height is 231mm? I was thinking using 1AZ block & crankshaft , with lower piston height & longer Conrod ?? How much the dish of piston & head combustion chamber is 63.5 cc ?? I saw the wiseco piston write as 2AZ head on 40cc ? Thank you.
Thank you so much for these videos, I’ve been waiting for someone to try this after reading about It for so many years online but no one actually ever attempting it. Now I know you said you were going for a turbo build, but do you think this setup would benefit over a regular 2az-fe naturally aspirated? Please let me know, as I want to do a high revving n/a build really soon. Thank you, subscribed
Hi Rich thank you for your kind words. Thats an interesting question. For me yes I am looking for a very linear power curve with good response, freely high revving nature and high power output. Is that better than a naturally aspirated 2az, well it depends on what you are trying to achieve. Some prefer the sharp throttle response of an N/A over a turbo but what I can say is that a 2.4L will always make more torque down low than a de-stroked motor. What is the purpose of your build and what discipline will it be used in most?
So i actually have a 2010 Toyota Matrix 2.4 awd, and I was trying to do a budget build, being that it’s an auto I didn’t want to go the turbo route for fear of the tranny not being able to handle it. Now I know I can send the tranny off to a shop like level 10 to build it but between that and the expense of the turbo it would be way out of budget. From all my research that I’ve done online I’ve seen a few people with fully built n/a 2az achieve 250 hp with e85. Read about TCPETE on scionlife. My build was gonna consist of port and polished head with oversize +1mm valves, Brian crower stage 3 cams with valve springs and retainers, 2az-fxe high compression pistons rated 12.5:1, 1az-fe knife edged crank, 1az-fe upper oil pan. As far as bolt ons you have plenty of choices, and TCPETE reached his numbers rather conservatively with off the shelf parts, 4-1 dezod red headed, weapon r Intake manifold, rx8 throttle body, nst pullies, I believe if he was to drop the extra cash on a custom header and intake manifold along with maybe individual cylinder tuning he could break the 300 whp mark on a n/a 2az-fe build. Now I know at that point your pushing it with budget but just an idea. And I believe with the 1az-fe destroke you can achieve even higher numbers being that you can rev higher like a k24 vs k20, obviously sacrificing some torque. The reason I went with the Matrix aside from already owning it and it being paid off, I love the all wheel drive and coming from a background of fwd cars when your pushing too much power after a certain extent it’s undriveable on the street, wheel hop, torque steer, I hate it lol All wheel drive you can launch the car, no wheel spin, not as much understeer depending how you have the suspension tuned up etc. the only disadvantage I have right now is weight, the car is a pig at 3,300 pounds compared to 2900 of a Scion tC, but with a gutted interior, bucket seat, ac delete, lithium 5 pound battery, custom carbon fiber drive shaft from the drive shaft shop, Carbon hood and trunk,forged rims, front bumper straight pipe exhaust, I’ve already taken out more than 300 pounds off the car, I still have yet to do lexan windows and gut the doors, maybe even a carbon fiber or lexan roof haha, sorry I know I’m rambling at this point, and a lot of people will say for the effort just buy a wrx or evo, but all this has been done throughout the years one mod at a time. I’m working with what I already have and I’m hoping to build an n/a matrix that can surprise an average wrx lol
Interesting build, did you get any further with it? Ive recently put a 2az in my celica gt4 and have toyed with the idea of a higher revving version. (take a look in my Instagram for the only 2az-fe turbo st205 celica in the world @adzn3k)
fucking genious... do you think that a stock 1AZ will support a TRD supercharger? i'm looking for that or fitting an AMR500 for a low boost (overland oriented) upgrade... i just wan't to go from 225-65-17 to 225-75-17 without hurting to much in the power department... i have a 2007 rav4 with the 1AZ-FE making 152hp
me too but doing the math first before throwing money at it will take the guess work out. I'm not in the practice of throwing parts at it and hoping for the best
@@MODIFYUP another problem how far is the project are you finished? I think you're going to stress your engine at 10 000rpm because of the large 86mm stroke
@@Manuqtix.Manuqtix i have updated the measurements since this video. I will now be running a 155mm c to c rod which will lower the piston speed and rod angle even further. by my calculations 11,000 is capable with the correct sized turbine to make power up there
Yo the AZ series finally getting the love
You're a legend.
Lots of great info here minus the aluminum rod to steel rod comparison.

Can the 1az fit the 2az transmission.

would you say 1az-fse is a really strong motor like the 3sge? i nkow 3sge can handle alot of abuse but unsure of 1azfse

So you're looking at putting the entire 2az rotating assembly into the 1az block if I'm correct? I'm having a hard time understanding this quite right
Ahhhh my apologies. I understand
I see what you did now. Looking forward to this build. Parts list at the end is super helpful!!
@@benandjakehuston6321 thanks for your kind words. so its a mix and match of parts between the 2, the most important being the 1az crankshaft.
@@MODIFYUP I'm excited for updates
@@benandjakehuston6321 coming soon my friend!
Need update dood!!!
Interesting build, did you get any further with it? Ive recently put a 2az in my celica gt4 and have toyed with the idea of a higher revving version. (take a look in my Instagram for the only 2az-fe turbo st205 celica in the world @adzn3k)
interested to see how you manage oil pressure/volume at 10,000 rpm. the stock oil pumps look pretty weedy
Actually going to look at the 2AR pump to see if i can adapt shortly. Gears are much wider.
Is this 2az are same with 2az from 2007-2009? Or before?
fucking genious... do you think that a stock 1AZ will support a TRD supercharger? i'm looking for that or fitting an AMR500 for a low boost (overland oriented) upgrade... i just wan't to go from 225-65-17 to 225-75-17 without hurting to much in the power department... i have a 2007 rav4 with the 1AZ-FE making 152hp
Any updates??
Whatever happened with this?
Where the shiz do u get custom pistons fer 1az??
show us the result of this modification
3:35 thats why various 4afe and 7afe engines made n/a more than 260hp, something that was not possible from any 4age/7age
Downside is a taller cylinder head which is problematic when dropping the engine in something it wasnt designed for :( bonnet clearance is a headache
Can you point me to good reads on this subject, techy articles, etc
