What would be required to obtain 300whp and the ability to reliably run your car night and day without worrying about the engine blowing up? Is this something the engine can handle on stock internals or does it need to built? If so, what would need to be built, lets say not to exceed 400whp? And aproximately how much would it cost? And can someone link me to a nice build-up of the 3SGTE engine? I've ran a search and all I could find were questions related to the N/A TO 3SGTE swap. Thanks in advance.
For 300rwhp, I think you'll be fine with a fresh rebuild and replacement of any parts you feel are worn. Maybe have the head surfaced and the injectors balanced etc... but probably not necesary. Run a good synthetic oil and probably install an intercooler to keep the temps down during the hot season since it's going to be a year round driver. It might be a good idea, when tuning, to aim slightly towards the rich side as this will also help during the hot season (this will also require more regular maintainance like replacing filters) although Im not sure if anywone actually does this.
But the man to ask is JekylAndHyde, especially about going to 400rwhp since Hyde is currently pushing 440 rwhp. I don't think his cars are daily drivers, but I'm sure he'll know what advice to give.
depending on the health of the current motor, you COULD still use the stock motor with an upgraded turbo/fuel system and some sort of EMS (eliminate any sort of "black boxes" tuning for reliability)...that alone will prolly run you anywhere from 3-5gs...building the motor with upgraded internals will run you around 2-4gs....factor in cost of installation and tuning also and other supporting mods too....
Yeah, speed is never cheap. So you're saying about 5g's - 9g's. So if I take the average of the low and high, it comes to 7K, without tuning and installation. I don't think that's bad at all, considering how much some other engines cost to build. The turbine would have to be upgraded, correct? Because through my search, I read in a thread that the stock turbine has only been tested to around 300, but never supassed that?
I hope your not trying to imply i'm a noob from the number of posts I have? I didn't create this thread hoping or expecting anyone to say $2,000 or something like that. I know how much work, detail, and time go's into a fully built motor. Having helped friends build H22A's, Ka24DET's, and SR20's, and even ABA 2.0L vw engines.. I know there's a lot of work involved. I'm new to the Toyota scene, having been a 240sx and Prelude owner my whole life. I just wanted to see how much it would cost roughly for MY power goals of 300-ish horsepower, which from the grasp of my searches on here.. is more than a realistic hope.

I know, he's cool, he helps everyone on the forums out. I saw that there were a bunch of how much for 3,000 horsepower type threads and that is always annoying, but in my research I just wanted a direction and goal of how steep to go into my pockets for that 300 horsepower. I read articles and builds night and day and i'm just not so familiar with what parts would require changing for 300rwhp reliabily daily driven.. every day of the week, about 60 - 80 miles a day. I know Arias, JE, and a handful of other companies make pistons for the 3sgte, but what other internals, bottom end or top end would need to be changed and who here is running a similar set-up? That's what I was aiming towards, sorry for any confusion.
its not so much what goes into the motor....its who builds it also...like i mentioned earlier....stay away from "black boxes" tuning....go with some sort of stand alone EMS and find a compentent tuner....

not at all... actually, I thought this was a good post. it answered some questions for me too. and I think the term "noob" isn't defined buy the number of posts, but the actual questions being asked and how they're asked..you can be new to TN but have plenty of expertise with cars/engines ...... anyway, no offense was intended
So theoretically, I can run close to 300rwhp without tearing the engine apart? It all depends on the proper fuel management, etc? I really wouldn't want to jeapordize the motor though. Currently I have the n/a motor in my 91 mr2 and I wouldn't mind buying a 3sgte and having it built on the side, because I have no down time.
Is there/ Are there any TRUE/TRIED performance engine parts for the mr2?

you should register for www.mr2oc.com if you haven't already. Toyotanation is ok for mr2 stuff, but that site has everything, and everything you would ever need/ask. Not trying to deter u from here, just trying to point you in the right direction.
They have stickies and stuff for the exact question you asked.
