Can you please make a video for 2jz GE and what are the difference on building them. Things you could get away with when building a 2jz GE. Things of that sort. :)
They follow the same principals. Just use GE specific headgasket thicknesses. Since the compression chamber is recessed .030" to provide optimal squish at a thinner specific compressed gasket height .010" vs .050" for GTE heads.
Same shit different day
I've heard GE heads have a slightly better intake port after porting other then that all the usual differences from a n/a to boosted
You can use a thicker head gasket to lower your compression ratio to 9.5 or 8.5 like GTEs. Also can be done with the pistons or head work. Weaker rods and no oil squirters is the only other difference in the block, heads and cams are different. So if you have an NA and want to turbo it, get new rods and a thicker head gasket or if you're really feeling fancy some pistons.
@@shadow105720 you should change it by using GTE pistons cause squish is negatively affected when you just use a thicker head gasket (when keeping the GE head). if ur gonna swap to GTE head you are forced to use a thicker gasket.
Always a learning experience listening to Jay...even it's a bicycle 🇯🇲
Another awesome video...I spoke to Cory when I was ordering my piston and rods and he was very helpful and guided me in making the right choice.
Always great information with you in front of the camera Jay! Great video
Thanks Jay. Good advice that I certainly will use when I rebuild my engine. Great video.
love it, great knowledge shared as always
truly appreciated
Great explanation. Great content. Communicated seamlessly.
Look forward to the rod video: with those BC titanium rods Jay!
Jay, I still want that Top End builders guide to complement the Bottom End builders guide you made a few years ago. 😉👍
Also, CP Carillo with .250" pins FTW. 😁👍
where can i find that guide?
Very informative video, enjoyed every bit of it.
I really wish that Jay still offered built short blocks. The vote of confidence knowing that was done ✅ correctly without question ⁉️. I've valued Jay's advice ever since owning my Supra. Huge Props.💯⭐🏁🏁🏁🙏
Thanks for sharing very informative
U are the best on this
thanks Jay, i appreciate it.
Great content Jay...should I buy the car first or start with the pistons?
Thanks. I bought the 8.5:1 87mm je pistons a couple years ago and am doing another rebuild as my oil pump went out and my cylinder got scored.
I' was curious on why I went 8.5:1 at the time and not 95:1 to and you explained it great. Thanks
I went with Jeff's recommendation from CNC Werx to go with Traum pistons fir my B series boost build along with CSS on the deck. Hoping for the best👍
I put CP Pistons in my 240sx back in 2000 👍🏾
We need a Jay EJ video. I know the pistons go the wrong way, but your knowledge in everything would help me SO much! I'm building a 257 type ra hybrid ej with port matched 2.0 heads with Bc272 cams. Any info would be awesome!!
Another banger video jay🔥🔥
Quick question Jay if you don't mind I was doing some research on compression ratios and since you mentioned it can I have your opinion? I unfortunately don't have access to ethanol based fuels,best I can do is pump 95 octane, so what compression ratio would you recommend for around 1000/1200bhp. ?? Engine will be a fully built coyote 5.0 with twin turbos, stock compression is 12/1, people run around 700 whp before running into knock and changing over to e85, I feel that 9.5/1 compression is alright even though it sacrifices power and drive ability before boost,but feel that being able to add more boost with less compression is a safer route than running really high compression and less boost. Your thoughts ????
Jay can you make a video on the best way to store a running engine long term or one after a rebuild that won't be run for some time
I know its out of your control but cant wait til you guys get those BC 276 vvti cams in stock again for my build!
Could you talk about the effect of quench when using different head gaskets please
Your my professor👌 with my in mekanic🙆🏻♂️🇱🇧🇱🇧♥️♥️
I like all video's 👌👌🇱🇧🇱🇧♥️♥️
I love waking up to Jedi Master jay please keep ‘em coming
I have a good question Jay. What if a person wanted to use a F-1A91 procharger on a VVTI 2jzgte street car?.
Great video. Would these same recommendations work for 1jz’s?
Yes
I have an IS300 with the stock 2jz-ge, i am going to turbo it and put a CD009 trans in it, gonna shoot for 8.8-9.2CR and 350-450hp. I want to be able to run 93 octane or E85 and any blend in between. I want this car to be able to go to the drag strip, drift track, and AutoX.
Cool plans bro
Im a huge fan of my wiseco 8.3 CR pistons. With the gte gasket and head decked accordingly thatll put me around 9.1:1 perfect for everything you just listed. Cant wait to get my is300 running and tearing up the track
@@mkgxcommanderx i’m confused , 8.3:1 pistons with a thicker gasket will get you higher compression in the 9:1 range?
@@bigjdm5460 the labeled compression might be in a stock Supra motor, but it’s really defined by the dish of the piston. Compression ratio calculators don’t care what CR your pistons are labeled as, just takes into account the dish on the piston. Decking the head made it lose a nice amount of volume in the combustion chamber I.e higher compression ratio.
Helpful info but I can't afford any of them lololol I watch you guys build and race them
Hello Jay. Maybe a stupid question. Do you use or recommend using piston oil squirters on a street drag car like Geo had or Pedro has? Or do these cause issues in high boost, high hp builds?
I guess that could be a loaded question if you have a stroker without the piston machined for clearance.
They're not needed when running E85 or similar fuel with great cooling.Oil squirters also takes away oil pressure.
I'm in the middle of doing my build on my Supra. Plan is a 94mm stoker with 9.0:1 backed by a T56 faceplated trans and a custom twin setup with G30-770 turbos.
G25-660's would be a much better choice you want a lag monster
Why 9:1 and not 11:1?
@@ricardo9628g25 is to small , at that point that’d be just slightly upgraded stock frame turbos I feel like
You da MANE ! jaY
Does compression for GE VVTi follow the same standard for the GTE. I’d like to run pump gas, but the GE comes with a higher compression. Should I lower it or keep MY stock compression?
yea that 91 or 93 is not up to par for that high compression. your not going to be nerves everytime you rip it. i believe you have to go with a GTE gasket and run e-85. Then rods won’t allow any power above 400whp “they say”. I’m on GE-Vvt-i block but i have new GTE pistons , H - tuff rods, King Xp bearings ARP head studs etc. Do it once do it right. I may get forged pistons too .
how can i make my bone stock engine last longer and make it even more reliable than it is?!
(i do change my oil often than it sayes in manual)
How about some straight 6 BMW love, Jay? N54, N55, B58, etc. We need some proper engine builders to turn to. 😀
Yes!!
i have Manley H tuff rods , with GTE pistons on a GE VVTI block. looking for 670whp max on e85 G35-900 turbo. I hope the GTE pistons will survive.
Defends on how much boost , mine lasted 3 years with 640hp at the hubs running on e50 mix at 1.7bar of boost before I cracked the ringlands
@@Paulythemanthanks, my OS GIKEN TR2CD just came in and I’ve decided to go CP pistons 9:1 compression. The 1,200.00 dollar pistons. I may go G30-900 1.06a/r divided.
is there a piston that is built for light weight, not big horse power for 2jzgte?
hey jay can you do a video for the 7mgte engine
Step 1: Rip 7M out.
Step 2: Put 1J or 2J in. 😎👍
Or
Step 1: Replace head gasket and/or head.
Step 2: Bolt the head down properly, not like Toyota did it in the first place anyway. 🤦🤷
This makes me feel like I have made the correct decision, I'm in Europe and E85 isn't a thing here so I will run pump gas, I went with a Wiseco piston as shown in the video with a CR of 8.3 to 1. together with the "0.200 pin it will be a 1000hp piston and rod combo, but I will only be shooting for 650-700 wheel. thanks again realst!
interesting, because Europa always pushed hard the environment bs and don't use E85. here in Brazil, we have E100 in almost every gas station, so don't make any sense build a engine to run pump gas
Holy crap there's a 3.6L stroker now? I remember Titan or someone making a 3.5L 10-15yrs ago and nobody would touch it, everyone wanted the 3.2L-3.4L. Are the 3.6L strokers used in drag racing any? Haven't followed Supras in 10+ years so im a bit out of the loop.
Tomai made it dude. Not much history on it.
Jay has a 3.5L in his own car now. Lucky sod is using a BC lightweight 96mm crank.
Titan sell short blocks with their kit in too. I'm hoping realstreet begin doing this again.
Thoughts on wisco 9.5:1 pistons
Good
Look more 2j content for you.
Me with a d16, hmm interesting
Hrmms the 2jzgte has a smaller bore than a 6g72. 2jzgte=87mm, 6g72=91.5mm bore. For a 3.0l 6 cylinder. Pretty sure the 6g72 has a shorter stroke than 2jzgte. That's were they made up the difference in displacement. More evidence a 6g72 could be a really good high compression, high rpm Naturally aspirated engine. As opposed to boosted. Just seems better suited for more rpms. Comes with 7000rpm redline.
2JZ has a stock bore size of 86mm
2j is a square 86x86 mm stock
@@tadda6282 ok i was off by 1mm but i was right about the 6g72 having a much smaller stroke. 6g72 is 91.1mm bore and 76.mm stroke. Pretty good evidence the 6g72 is built more like a high revving honda engine than a boosted v6
@@supradma71 gotcha i was like 1mm off. on the bore size 2jzgte s 86x86mm bore x stroke, and the 6g72 is 91.1mm x 76mm bore x stroke. 6g72 is built closer to a honda engine. Wide pistons+short stroke = rev happy engine with lower torque.
91.5mm is a lot of piston to be throwing about. That's why is has shorter stroke.
You'd have to work it out. But the smaller stroke doesn't mean it's an obvious less stress situation. As there's more piston mass.
Ask my papi chulo if he can make a video on high imp vs low imp injectors pros and cons (if any) and maybe slide into meth inj dos and don't 🤷🏽♂️🙏🏽
I use nitrous as my stroker. 😁😂
so much knowledge, so little money...dont know what to do....
