a 2jz is more expensive than $3k. its way more expensive than either a rb25 or vg30. if it only cost 3k then no one would do any other swaps. thats the same price as a sr20 swap if done cheap. my vote is for the vg30. while it may be more expensive to mod, it has a huge proven track record of awesome performance. plus you can get the actual engines cheaper than an rb25. it comes stock with more power. and a stock 300zxtt will outrun a stock 350z. so put that in a lighter 240sx chassis and you can definitely outrun your friend (unless he's done a lot of modding). of course the rb25 is good too but why get a 2.5l I6 when you can get a 3.0l v6?

you also have a nice point. thats why choosing an engine for a swap is so difficult. ppl know the differences of pros and cons better than some others.

The 2jzgte you can go buy the harness and every part in your local Toyota dealer.How do you see a local motor being more cheap then a ....I hate saying this JDM motors.Makes no sense.Don't look at the shorter picture.You will want to mod any motor he decides to buy.Being smarter is a most if you want to be competitive in this motor swap going on today.Thats all.Thats just my opinion thus...:scratch:No offence

take the ls series for example. they are still pretty expensive. hemis are still expensive. they might be local motors but because of their demand they are so highly sought after (and keep in mind that though they might be stateside, there are not as many good engines left as you might think) the prices are still high. the only thing i can find for around 2k on ebay is 2jz's with auto trannies or 1jz's with 5spd's. also you can buy every part at your local dealer for the vg30 as well. and back to the 2jz's. you're looking at an average of about 2100 for an auto tranny ecu engine and harness. now you need to make your own parts or buy a kit which i presume is going to be more expensive than a rb25 or vg30 kit. i don't see how it can be less expensive or even the same cost as the vg30 or rb25 swap.

i was thinking it would be cheaper to buy the vg30dett motor and uncut harness for less than 1,300 shipping included, and then just buy a vg30de 5spd transmission from a junkyard here for about a 100 bucks. the motor has anywhere frm 280-300hp stock and 283 ft/lb torque. i personally see that as a hell of a good start in hp for an s13 chassis eliminating the need to buy parts to increase hp and torque just because its so powerful stock. in other words ill have a powerful car with only a swap. later on giving me the opportunity to build it when i feel necessary.

the engine i am getting is a 90-94 model so its should be ok. as far as fitting it will have twin turbos so that will eliminate headers. all i will work on is the exhaust i know this swap has been done before i will look on google for things done to the engine bay for the swap i have yet to see a forum on here about a vg30 swap

I just watched the beginning of a VG going into an S14 today.. its a tight squeeze.

I noticed you said all you wanted to do was beat a 350z? Is it turboed/modded at all ?

Because i can keep up easily with 350zs in my camaro (beat them off the line is a breeze). Its a stock LS1 rebuilt a couple years ago, i'm giving one vote to that.
Alternatively, i'm pretty confident a KA-T will also frustrate your friend aswell, theoretically, all you'd have to do is build one with matching/exceeding the power of his 350 and if he's stock, its commonly attainable to match his 290-+whp with a nice size turbo setup.

mind you, I'm past 3k into my ka-t build and it hasen't even begun yet. But think of it this way, his car will still cost 10+ grand more than yours will and your keeping up/passing him with any build you succeed in.

My neighbor is thinking about selling his RB. maintenance and safetycheck is another thing you gotta worry about with those. if you don't know anybody its very hard to own a street-driving RB legally. same for any JDM motor. but the SR and 2JZs are easier to maintain since more parts are local.

you could also look into 7Ms. its got a similar rep as the KA around the supra forums in the way that it was overlooked for a JDM motor.

a turboed 350.. well that changes the rules a lot.

the RB25 or LS1 supercharged might be your best bet. but the best way to estimate when a project like this will be complete (if your not rich and obsessively motivated) is to make a modest estimation of time, and then double/triple it.

the quickest to obtain will probably be the LS (out of a late 90s camaro/firebird/vette etc). and for sheer numbers its a very comfy motor to get you there.

my camaro is already amazing, in a light 240 body i'd think it would be more amazing. but i've seen less than 10 mpg when flooring it. it gets almost 20 driving regularly.

i still say the vg30dett. it's be proven strong enough to produce the same numbers a turbo vq35 can.it can out power an rb25 and though an ls1 is nice i would still prefer an vg30. plus a vg30 is cheaper since you buy 6 not 8 of everything.

You have a point. as of now i will go check the hp and tq on the ls1 and make a few comparisons just to see how far off the vg30dett is from the ls1. either way its said these are two powerful engines and both will turn the s13 into a monster.

i have a ? on the VG has anyone done this swap and what mods do you need to do to get it to fit?

i would be goin into a s13....

I understand that you are a noob. i was a noob on this forum at some point, and i asked bad questions at some point myself and caused aggravation to others just because i didn't search properly. Now i see exactly why people were aggravated. i see from the ? you have just asked i can tell you haven't searched google enough. this is probably the nicest way that someone will say search your question on google before you ask here..

also consider that the LS has many series with different technology/specs between which car they were used in and the years it came out and some of the later ones were boosted. and while the VG is turboed, the LS1 (if you decide on the 98 camaro/vette version) is producing those numbers on raw motor (so if you turbo/supercharge it...:)

and the 6 Vs 8 isn't really that much difference in costs.

a japanese 6 cylinder twin turbo can cost more than a more common american V8. the VG is also technologically incomparable to a nearly pure-mechanical LS1.
If anything for either engine, the money will be in the fabrication more than the difference of cylinders

All a mute point without driving instruction and seat time.

Have we settled this month's "Which Motor" Thread now?
