:shock: I should of tried that! Thats a crazy idea!!! :roll:

Well my searching finally got something, the guys in this post mentioned 300rwhp, is that the limit before dealing with the internals? I'm thinking about purchasing an engine from rabid chimp but I really wanna know what is the peak hp i can get on a 6mgte. My car came with speed holes in the head gasket, so I'm looking at rebuilding or upgrading. Trying to decide on which. :?:

well russ m. did make well over 1000 horsepower on his :lol: so im sure you can get whatever you want outta it also. jus depends on how big your wallet is and how much time do you have to tune. goodluck

Well I bet you can get a lot of power like that out of the block, but I bet Russ M. had to do stuff to the internals on his engine. I'm hoping I can reach something like 350rwhp without touching the internals. Then I can go mustang hunting. :mk2vroom: Yeah Yeah!

So what's the most hp I can be running in a 6m without breaking the stock internals? [/quote]

im guessing 300rwhp maybe more if you tune it correct

It really depends on how long you want it to last. The 7MGTE guys say 300HP is tops for the 7MGTE engine if you want long term factory like reliability.

eric is making 300rwhp and i think he has room for more. his motor also could stand a new set of rings and would prolly belt out more. i dont see why you couldnt run 400rwhp as long as its tuned correctly. theres a few 7m's over 500rwhp on stock internals. however, i dont expect they will last very long at that level.

Great, well now I know the engine can take 300 - 350 rwhp on stock internals, but maybe I'll get forged pistons just in case. So now its a matter of figuring out what I'm gonna need and how much to save.

lets see
-metel head gasket (I know the stock ones were made wrong or something)
-turbo
-intercooler
-exhuast
-fuel pump
-air intake
-turbo computer
-Aluminium pulleys?

Has anyone tried Aluminium pulleys? Is the a sizable/noticable hp increase? If so how much?

DO NOT USE AN UNDERDRIVE CRANK PULLEY!!!!!!! it is know they dont work. all you need for 300rwhp good stock ct26, 7m turbo manifold, 3in dp and exhaust, 295cc/min injectors from a 86-88 n/a mkiii, s-afc, stock mkiii fmic, i/c pipes, rrfpr, k&n filter, walbro 255lph fuel pump, and some dyno time to tune it. also, be sure your motor is in good shape. and retq the head to 75lbs/ft.

No, I would problably not use an underdrive crank pulley. Thats the one with a smaller pulley, right?

But what I mean is changing all the pulleys including the crank to Aluminium. The sizes of the pulleys would remain unchanged. That should be alright, right? Lighter weight means less power to spin making more power to spin the wheels, right? I'm hoping it makes a noticable hp difference. I learned that my girlfriend's Dad owns a metel shop, so I could make something like that no problem, just need materials and the orignal pulleys. So I'm thinking about going for it.

Thanks for the details on the other parts.

Does not matter what you do here on the crank pulley, even if you do go to aluminum. The point we're trying to say here is that MOST aftermarket crank pulley's DO NOT have a harmonic balancer on them. Certain RPM's you're motor will start making harmonic vibrations. Not good at all for the motor... Great way to shorten the lifespan of your motor, due to vibrations that are not supposed to be there.

Just make sure that your aftermarket crank pulley has a harmonic balancer.... Otherwise, you will have problems later.

Here's a link to an excellent article in support of Chris's statement about harmonic balancers. It is written by Steve Dinan and posted on the Dinan website complete with illustrations and references. Dinan tunes BMWs, but the information is valid for all cars. I'm sure all will find it helpful:

well, doesnt matter what diameter the crank pulley is, if its lightweight it wont dampen the vibrations and also, it is mallable and the crank bolt will not be able to stay tqed properly for long and you will tear up the keyway in the crank. ive seen it too many times on sf.
