Im wondering what are all of the big advanatages and disadvantages of running stroker kit
im asking since i want to get the low down on everything that is good and bad about doing a HKS 3.4L Stroker Kit.

i know a bad point (to some ) is
- price


i understand some good points are
-lighter and stronger than the OEM parts
-PROVEN to easily make more than 1200rwhp on gas, but what octane ?????
-quicker turbo spooling and torque

what else am i missing thow ?

honestly other than price there really is not downside to it... for a motor with a fully built head it may not be able to rev quite as high (500 rpms less) but should be safe to a little over 9000 rpm, but other than that it increases hp/tq, decreases lag, basically just increases power across the whole power band. i guess one downside is just all the machine work getting everything balanced, bored, honed, etc... but it is deginately worth every penny for what you are getting!

Don't worry about the revving capacity. The HKS stroker kit has PROVEN itself to rev to 9500 and beyond without any problems. You're going to be pouring money into your head and valvetrain to get them up to par with that speed. I think the only downsides are cost and time, as you're probably gonna wanna take it to one of the big name Supra sppecialists in the country to get the work done.

In all honesty, any good engine builder can put this together...its not like the 2jz operates differently from any other engine. As far as anyone is concerned it is the same as any other straight 6.

concrete motor means no more daily driving. the blocks water passages are filled so it cannot be cooled.

Please explain further about the block not being cooled. Isn't that a bad thing?

You can get away with no water cooling if you only drive 10secs at a time or less ...or thereabouts.

For example, did you ever see a AA fuel dragster with a water cooling system?

unless your running straight meth or alky, concrete in the block is out of the question, however a 3.4 with a 67dbb would have the powerband of a big block but still rev to 10K!

ok not the powerband of a BB we are only gain we arent makin this a 5 liter. But it will be a signifigant increase as well. I really think there is no real downside. Some people were saying you cant rev as high, but who honestly ever revs past 9k?

Ok, let's examine some rod ratios. The optimal rod ratio is considered to be 1.80, however the stock 2jz-gte is 1.65. The rod ratio on the 3.4L stroker is 1.45. There is a reason that HKS only recommends revving to 7500. Maybe the motors have been revved to 9500 by race teams, but that by no means is a SAFE rev limit. That should be taken into serious consideration before dumping 10-14000 dollars on .4 more liters.

Sorry to be the party pooper, but a lot of folks just jump on the bandwagon without knowing the downsides.
