Many factors play in to a decision and sounds like the 1J is a great choice. Before I sold my RHD 1J to my brother, it was an awesome car to drift and go around corners and it has a smooth transition.

Are you basically saying that you upgraded your 1jz to a better model
7m?:biglaugh:

It's absolutely possible to make a 7m reliable at 400hp for less than $3000.
I'd really like to know that you guys are smoking.
Both motors have good and bad aspects it just depends on which ones he likes.
I have no problems with the 1j it is a great motor. You guys are all talking like 7m's just explode unless you build the shit out of them.
Stock components have been known to handle 500hp+. I the biggest thing is how far he depends to go with this motor.
All this jz bandwagon shit gets old.

ATI pulley - custom but 2 months waiting period. :biglaugh:
if your on a budget it's hard to go jz... not because of the initial costs but b/c of the price and availability of parts. buying jz parts is killing my budget b/c i am still in high school and don't have a full time job. 7m parts are a lot cheaper to get.
This is for a different application tho Tun_x
Lets put it straight and simple. For Drag racing, you need outright massive power, and the best way to do that is with large displacement, the next best is to feed the engine more air(duh), Add a turbo! The 7M came stock as large displacement performance engine with a turbocharger.
The 1JZ as I recall, was developed for the 2 liter racing class(along with the RB25 and RB26, if i may go out on a limb and say so), and is a much more modern design. The M series engine, if I recall(again) was designed mid 1960? Now obviously things have changed dramatically from the first M, to the 7M, Turbo chargers, electronics, engine management, and for one, Power!
Again, I'm not pointing out only the Bad, I just do believe the 1JZ would make a better road race engine. Newer is always better, right? The 1JZ was designed in the late 80's, and was put into a Supra for the 1989 Model year I believe. And since the 1JZ's "race intentions"(It's killing me I cannot find that source!) it has a more modern, and sophisticated if I dare say, Oiling system than the 7M(yes, I have done more work on a 7M than change the spark plugs). Also, as proven between the 1JZ and 2JZ head flow tests, the 1JZ has a much higher velocity compared to the 2JZ, which flows better. When racing on a road course, Wouldn't response be great to have?
I'm not forgetting the Group A Race cars! But since it would be a lot of work(and money I would assume) to find a Group A race car from 1988 not many, if any of us enthusiasts would know what the oiling system was like! I know Ian(I.J.) has a Group A oil pan(Magnesium, and has a large sump), I was looking at a Group A, and a 1JZ/2JZ pan, and they are very similar. Newer technology usually puts things for the better, and you know Toyota designs for longevity, so a LOT of money is spent on that stuff.
These are two of the Best engines Toyota has ever made. May even be the last of the powerful motors from Toyota for years to come, Both motors came in flagship cars, we are lucky to be able to enjoy either as easy as the other.

The M family is a straight-6 engine design used from the 1960's through the 1990's. The turbocharged 7M-GTE was Toyota 's top performance engine from 1987 through 1992.
The 1JZ-GTE 2.5 L (2491 cc) 1JZ version was produced from 1990 through 2005

I say 1JZ because of the nature of the engine, and I believe it will perform nicely in a road race course.
it looks like 2JZ just isn't in your budget, otherwise I'd say it's the best of both worlds.

I've also considered 7M, 1J, or 2J myself and i just decided to build the 7M for multiple reasons.
1.Parts availability incase something breaks the day before a race you can just run down to Toyota and get it instead of having to import something
2. Its already in the car so no need to modify engine harness, motor mounts, throttle cable, etc.
3. If building a race engine, all the internals are going to get replaced with primo parts so i believe i could build a 7M just as good a 1 or 2J with the same parts.
But in the end i build my own CAI so i had to extend the MAF wires, and i'm building an FFIM so i may have to modify the throttle cable so now i'm right back to where i began weighing the differences. The only thing between the 7M and 1J is the old adage "there is no replacement for displacement". Its nice to have, so maybe 2J is the way to go!

I can tell you that I loved the 7M, with all that torque, right up untill I drove Nate's 1J Supra. Well, I guess I don't quite love the 7M the way I used too. However, Duane, and others have proven it's venerability, many times over.
For me, it's a JZ family future!:icon_bigg

Stock parts are obviously being tested at this power level we are at. :biglaugh:
im in the same boat I want to build a vette/viper killer which would be quicker and smarter to build? 7m/1j?
