Im going for a DD car, but also wanna drag it. Im 20 years old and the supertech low compression pistons require a boring of the engine. So i was gonna get shorter pistons to bring the compression back down. Also this isnt the first 240 ive worked on. Im pretty familar with the KA but of course i still have a lot to learn. I want to have the engine built so that it can handle anything i throw at it. I will start with a lower boost and work my way up.virus77 wrote:your gonna need low compression pistons for turbo and I dont see what it has to do with boring your motor out.
I really dont think you need titanium rods, last i heard they are around 800 a piece or something like that.
All together from the looks of things I would say you need to start at a little smaller scale than that for your first project.
What numbers are you going for? is this car for drag, drift, autox, daily driver? how old are you?
Thanks for showing me those pistons i didnt find any last time i searched the web. To many stupid websites out there. But why does everyone think i should start with a smaller HP goal? Ive driven an RB powered 240 that had all kinds of crazy **** done to it. We never got it dynoed but still had massive amounts of pull to it. Its jsut my first KA that ive built. Im not one for going small and just wanted to know what you all thought about the parts that i was looking at. A lot of great feed back coming from you all but i dont want a lower HP goal. I want a DD that can handle at least 400+ and then when i go to the track i can boost it up to around 500+. I know that there is no set of pistons that are out there that just drop in ...virus77 wrote:by going .020 overbore you are not going to makes the walls thin enough for it to ever matter. And Arias sells a stock bore 8.7:1 compression piston and im sure some other companies do aswell.
And if the titanium rod are that expensive then they are out of the question for now. How much HP can a set of forged rod handle?virus77 wrote:I really dont think you need titanium rods, last i heard they are around 800 a piece or something like that..
I want some parts that exceed what i want for now because like everyone says. There will never be enough done to a car to satisfy any man. So why waste the money on some lower quality stuff instead of just going all out on the first try. Im going to have a seperate motor that i will do eveything to so... the length of time that i have to build the motor isnt an issue.virus77 wrote:All together from the looks of things I would say you need to start at a little smaller scale than that for your first project.
Stop. Fail. Pack up and go home. Not boring the block on the average 150k motor rebuild is stupid. Man up and take the 80 pound empty block, and $50 to a machine shop, and have them bored out.Next: destroking is $3k from Crower. ITravBear2 wrote:Im not really into boring out the engine. I wanna give it a shorter stroke though.
Why would i be asking if i knew what it took. Im trying to learn before i do all of this with a KA. Ive never built a KA. If you look back at my posts they have all be kind and says thanks for the info. I have have really appriciated the feed back. But to come and tell mehuguetpj wrote:I agree with PapaSmurf. You're asking questions which to me say you really don't know what it takes to get 500WHP out of a KA.
By the way.. the Pauter forged rods are advertised as able to handle 800HP.
Something like that is much more helpful. And jsut because something is advertised to handle 800+ hp doesnt mean that in the real world it will. Because stuff has flaws and doesnt always work as it should.PapaSmurf2k3 wrote:Forged rods can handle over 600 hp.
Tell me. How did you learn how to handle what happens up there? Did you experiance it before your car was able to handle that?PapaSmurf2k3 wrote:oh btw, if you dont know how much forged rods can hold, how do you expect to know how to keep everything together at those hp levels, Up there, crazy stuff happens all the time. spark blows out, boost leaks develop, and SERIOUS tuning is needed... all of this is WAAAAY more complicated than "knowing what a forged rod can hold" but uhh... good luck.

Thanks for the comment. Jsut because ive finally got some money. Someone without any wants to put me down. If it was about more money then brain i would be paying someone like you to do this for me but im not im trying to learn all this so that i can do it myself. I have a passiopn for cars and have all my life. Im sorry that i went a different route then you did and choose to save lives instead of build cars. Give me a break. If i didnt want to learn i wouldnt be here asking questions.toki wrote:lol @ thread starter.

I can see where you are comign from. I know that a hone is in need but i just didnt wanna go with a full bore. I can see where you were coming from earlier when you said the were on it would already be quite a bit so it wouldnt make that much of a differance. I wasnt thinking about that. Maybe a 20 over is needed. Thanks!nissanfanatic wrote:Full engine rebuild would include at least a hone... But.. we just can't quite see what you mean by putting pistons in without doing some kind of cylinder preparation. It just won't last very long if it even works...
Thanks thats really helpful. I was thinking about the Stand alone. Also about the t3/t4 i planned on starting off with that and then moving up later on when i learn for to drive the car. I jsut want all of the internals to be able to handle anything What turbo do you think i should go with. Ive been reading the Garrett site on how to do the turbo mapping thing but i havent yet got it down.lilskyline240 wrote:Guys, just lay off the guy, hes just tryin to get some info on his build before he buys the wrong stuff or does the wrong thing with it....Hes a beginer in this world and needs a little help and guidence...why push him away??? End of rant
your setup sounds good, but i would think about boring out ur cylinders for the reasons taht everyone else said...helps seal the rings better....also i would go with smaller injectors or your gunna be burnin gas like crazy...Ull need to get ur ECU reprogrammed for the injectors and new MAF by either JWT or Enpathy....for the exhaust manifold i would go with the IAP one cuz i havent heard a bad thing about it...also if your lookin at achieving that kind of power get a stand alone engine manage ment system....to control every aspect of your engine...in that case you wouldnt need the ECU tuning.....if the engine manage ment is too expensive....ull need a Boost controller....and you said u want to build a project for 500+ hp potential, a t3/t4 turbo wont cut it...youll need a good garrett BB turbo...and a good tial wastegate to go along with it....hope i was of some help
Well i would personally go with the GT3251e....good for bout 500hp and its BB so fast spool up..... and like nissan fanatic said....SAFC and tuned Ecu may be a better choice for u right off the bat....and with not gettin the full engine management, ur savin urself a ton of money too....but im tellin u right now, a 500hp, or even 400hp daily driver...is NOT a smart plan....TravBear2 wrote:Thanks thats really helpful.
