im thinking about putting a 2jz in my z i really like the motor 2jz but i love the looks of a 300 any thoughts?
has been done. do a search, i think it was extremely expensive. out of interest, what is it you like about the 2j? because any performance you can achieve on a 2j you will be able to achieve on a vg30dett for the same money when you include the cost of getting the 2j in the zed (ie10k mods on a 2j + 10k custom install is probably going to get you similar performance spending 20k on a vg30dett) if its the exhaust note you like then you can do a single on a zed with a garbage can tip, but to my ears both sound crap. will you be putting a getrag 6speed behind the 2j? or the 300zx box?
i have the $$ its more a matter of i like how bullet proof the engine is and how much easier to work on i would just be dropping a 2j in prob keep the 300 box but upgrade it and eventually and im no mechanic but i have done work on cars i took a good look at the vg and straight up its to complicated for me to work on the 2j is much easier and i think will make a pretty good project to keep me occoupied for a good long while
Vg will never be a 2j. And conversions are easy you guys make them out to be so expensive. I don't know how yous get 10k for the conversion 2js are cheap in auto cuts like 2.5 k and if you think it would cost more then 5 k to get in and running your crazy. In a shop maybe. Then that leave mods to come!
So the VG is too complicated for you, by just looking at it, and you'd rather attempt an engine conversion to make it easier? Shit man, i started out knowing NOTHING about the VG, let alone many other engines, and within the first 12 months of ownership i could solve most problems. It's not that difficult to work on! It's just a cramped engine bay, but is essentially the same as any other engine. Not having a go at you for wanting to do something that is relatively unique, all the power to you...but don't do it just cos you think the VG is too hard to work on. It's like saying 'oh it'll take too long to cross this river in my boat', i know, i'll DRAIN THE RIVER!!!
well you've probably got two of the most important ingredients.... time and money honestly i'm not trying to convince you not to do it, too many people on forums ney-say about every idea other people have that hasnt been done 1000 times. just really hate seeing half finished projects or projects where the owner is disapointed at the end. the rep of the 2j for being bulletproof is, in my opinion, a little overdone. supra forums are soooo full of fanboys it can be hard to ever get good data on the engine. yes on the stock bottom end they can make a fair whack of power, especially if you add a good single turbo setup. notice i said good, which is not cheap if done right, cause a cheap ass single turbo wont give you the killerwasps and wont last long. as an aside i know of more than a few 'bulletproof' 'fully built' 2jzs that have been killed by fuel pump failure. yep that can happen in any car but thats my point, dont think a 2j is a free ticket to trouble free motoring. dig into the supra forum and you;ll find the 2j has its share of VTC gear/seal, electrical, harmonic ballancer, valve guide ect ect ect issues. granted definately easier to fix in a supra than a z due to engine bay space, and somewhat cheaper due to there only being half as many of most things, but there is a massive 'performance' tax added to all things 2j (read ripoffs taking advantage of fast and furious fanbois) anyway end of negativity now. the 2j is a great engine. no doubt, you'll need a custom spacer or bell housing to use the z box, which is no getrag but should take the power fine. something tells me though that gearbox mounting will be one of the smaller challenges to address. good luck with it if you go ahead ps e-z i just grabbed those numbers from my ass for example, but the one successful 2j swap i've heard of in AUS ended up costing about that. it may well have been in a shop, but add in custom sumps/cross members/gearbox adapters, possible firewall mods or a funky rad setup, exhaust plus working out the electricals it could well add up fast. if you can do it for a whole lot less then great! infact i reckon you'd have a small cottage industry on your hands cause every 6months or so some1 asks this question.
I would do ls2 with twin turbo set up or vr38dett with mods if i had my time again, or you could buy my motor cheek out rebuild threads for specs only done 3000km since rebuild
Your the only crazy one here thinking it's easy. You don't know how much modification you need to do to get in. It doesn't bolt right up. That motor is longer than the vg, you will need firewall modifications, engine mounts, custom radiator and intercooler, whole new exhaust design, not to mention all the custom fabrication to mate it to the gearbox. Mod for mod, the Vg produces as much power, with even more useable power down low. The internals might not hold 450rwkw, stock, but you'd be silly leaving a 2j stock anyway. Whatever you do, goodluck, but asking that question here, take some advice from people that have done conversions, and researched exactly what's involved in a 2j swap. Bang for buck, you will always lose.
Lol at ppl telling me how to do conversions. I know what's involved. It's not hard. But I guess it's easy when you can wire, weld, fabricate for yourself. Give me a 2j and 10k I'll put it in any thing. You can get front, back, mid sumps from different engines and bodys that fit right on. Orrr cut and shut a custom pan and pick up. 10k from a shop is fair, they have to pay wages. Doing it for yourself for the first time budget 10k any way. I don't e war so hood luck with what ever you do and feel free to pm me for some brain storming.. Peace
No engine will be bullet proof with a crap tune. It's all in the tune. Different motor but I have friends with 400+hp dead stock na rb30 blocks. But very good tunes. It helps alot
So what makes the 2jz so bullet proof??? Is it that it runs a chain setup instead of timing belt? Is the block thicker than the VG or are the Cylinder walls thicker? Is the crank thicker? Everyone goes on about the 2jz stock bottom end being able to take HUGE h/p but at the end of the day we are not in the 90's. Things have moved on and there is a massive aftermarket support for the VG. It's not like the VG can't be opened up and internals be replaced with Forged and bored out if the ultimate power is to be had. In all honesty, people are intimidated with the ZTT engine bay and the whole car technology in general because of 1st appearances. Personally, it's easy to work on the Z engine. Take a few hoses off and the radiator and the whole engine bay opens up. But the TTZ does have a scary feel about it at first glance, even for die hard backyard mechanics. Peter
I completely agree with above. I bought my cima thought bugger this engine. Now it's z32 powered. Now don't confuse my above statements with hate on vg. I love VGA and have been converted. I love them. But why not 2j it
20 years later and they are bringing the 2J back to life in drag racing (pro fx) because of it's proven high power making ability's, the VG30 is very underestimated due to people being too scared to work on them, If you were to show people how easy they are to work on and the power output they can achieve then I am sure there would be a lot more getting money spent on them.
LOL no one is warring... You asked the question. We answered. If you say you can put a 2j into anything then why ask for our thoughts on it?? You obviously can't hack some negative feedback. So go hard man, have fun... Such attitude for what???
I'm not doing shit. Or asking for opinion. I'm answering his question. And ppl are giving mis informed information.
