stroke
 

is it posibale to stroke a 7mgte

no offense but are you for real?

yes but not worth it.

why isn't it worth it?

The 7M is already a relatively long stroke engine.

Your best bet is to boreout for more displacement, the 7m is a VERY long stroke, look at the redline. Personnaly I don't think boreing is worth it with these engines, you can already produce a pile of horses with simple forced induction, intake, and exhaust mods.

Take a look at this kit here.

For the price they are asking you could probably do a full 2JZ-GTE swap over.
The claimed increase in power though looks good for both engines.

what does it to mean stroke an engine?

To increas the stroke (the amount the piston moves up and down in the cylinder). This is done by replacing the crankshaft. It increases the displacement of the engine and (usually) the power output.

The downsides are:
- Can lower the max rpm (all other factors being equal)
- Can make the engine worse for turbo charging (not sure of the reason, honestly).

ohh thanks bud

when you stroke an engine, you increase the displacement. im not sure how much the strokers for the 7m increase displacement but i know hks has one for the 2jz that ups it from 3.0L to 3.4L which is a significant increase

i would rather go with that ^ than spending $2500-3000 on a stroker kit

or if you have alot of money, do both :D then it will be hard to catch you. money always limits everything.. and time.

jepz, why would you ask if he is for real, thats a valid question. Maybe he doesnt know what exists. As for stroking the motor, For an n/a, that would be a good upgrade, but not so muhc for boost. The increased displacement makes the turbo overspeed(it also spools faster), It would also move the powerband down because the valve timing is setup to flow a certain ammount of air for 3 liters, not 3.6. And at lower rpms your not making as much advantage of the available boost, And because the cam is going to be timed wrong now, wont make much up high either. It would add HP, just because your getting more air in, But not as much as if it was all set up right for the increased CCs. It would also make the crank weaker and easier to break. and you have to get the ecu reprogrammed on either motor anyway. But on an n/a you want the extra CCs to make up for the lack of boost lol.

well hks must have known something we don't for they destroked the 7m to a 2.8 and twin turbocharged it
8sec 1/4's :love:

Yes, You want a shorter stroke/bigger bore motor for boost/highrpm power. Long stroke for low end/midrange. If you bored/stroked an NA 7m motor to the 3600ccs as listed on that site, If you got the right cams and head flow characteristics, It would be good for some awesome power.

ya it was a dumb post... i post on mood, meaning sometimes i feel like being obnoxious... like that... and sometimes i feel like being helpful... sometimes i just like to say something... sorry...

Haha yah me too, But you make the newer type of people feel dumb :(
