Ok so my original post didnt make it because I am having some issues with the net.
I cant duplicate what I originally wrote but I will try. The reason I copied this thread title is becasue I came across some questions that I think prolly dont belong in his post.
I noticed that it was pointed out that the stock internals are ok up to 350hp.
I havent checked my compression or anything because I was considering a build, so you have an idea. I wanted to put the time and money in to it cause I have never been one to like to redo my work. I was aiming at the Arias pistons, crower cams, supertech valves and all the machine work to match, ie. head decked rods shot peened and a good PnP. I know what I am looking at is a whole lot of money and thats ok if that is what I want. My true questions arose about the transmission. How is the 5 speed. What does she handle. I havent made any final decisions because I dont know what I truly want. I mean 350 is alot in the 240. I guess I dont know much about the "scene" as someone tells me, because I dont go to races and havent seen what really goes on. All I know is that when fast and the furious hit the scene. I wanted something that wasnt V8 powered. I dont want a show car...I dont even want a radio. I dont know if I should spring for the build and just keep it low until I see how much that power is, or I could just put crap parts on it and see how I like that, if I want more I will then have to do the build.
What did you guys do to decide what you have now. How many different setups have you tried. I mean I see Ivans car and I would love to see it in person but I know I aint ready for anything like what hes got. hat is frickin nuts, but I do want the intake and mani they come up with. Even if it just sits on the mantle cause that is freakin awesome. Well just some late night thoughts. Oh and the reason I am a noob poster is because I try to read as much as possible. I even read the BS posts because somewhere in my mind I have asked that question found the answer and then forgot it later on...lol. Well later all. Thanks for having such an awesome website.

Hey dude,
Glad you are reading before asking.
As for the rods, if you buy new ones you dont need to get them shotpeened. Shotpeening just strengthens the rods by reducing any stress risers which cause weakspots.
The biggest question mark on the stock KA IMO is the stock piston ring lands. They are thin and weak, compared to forged pistons.
The transmission is affected by 4 things...
1- clutch. If you have a unsprung 4 puck clutch and running with slicks at the drag strip and powershifting you are much more likely to break the transmission than if you have a full face organic disc and run with street tires.
2- I already mentioned tires. If you have tons of grip it'll put more stress on the driveline, especially on shifts. Think about cranking on a stuck bolt. Impact works best to break it loose. Well, impact is your enemy in trannies.
3- It also depends on how fast you shift and if youre always grindin gears. Fast shifting tends to lower ET but is not conducive to having a reliable gearbox. Watch any accomplished road racer - they never hammer through the gears.
4- A more minor consideration is transmission oil. Good oil will go a long way to preserving the guts.
I would be confident with the stock transmission for under 400whp.
As long as you arent trying to break the transmission it will be fine for those power levels.
Right now I'm running about 300whp on the bone stock engine and with proper tuning, it has been flawless.

Re: (NateDogg)
Hey thanks for the info....greatly apreciatied. You say that you run 300hp. Is this your daily driver? If it is how do drive? Are you agressive sometimes, all the time? The reason I ask is because I will take whatever steps to prevent problems as this is not my daily driver, so when I do drive it it will be driven.
Back to you running 300. Are you pretty satisfied with that power or do you want more. You said you had been running your setup for some time now and I am curious if you are still satisfied or has the yurning for more power come in to play. I wish I could just drive someones car that has that power and see if that would satisfy me long enough to make it worth my while.
Would say it would be worth getting the rods too if I am doing the pistons and everything else. I looked into the AMS rebuild kits and I dont know a whole lot about the power ranges of each kit. My main concern is that I build accordingly. I dont want to put alot of time and effort into something that isnt gonna make me happy or that will crap out on me. I have seriously thought about getting that $375 advertised on here. Cant remember the size though. Adding an ebay mani and fmic and Megasquirtin' it. I am not the smartest when it comes to cars. I can do some electronics though. Between my cousin and I we could rewire and reboard a plane....Navy training. Thats a plus. I really wanna tinker with that setup but I dont want the investment to turn out to be a money pit thing either. Either way I am gonna do the rest of the car the same. Completely gutted with the bare essentials and a nice suspension. Havent decided which way to go with that yet though. Way too many options.
Really this is what is holding me up. I wont pull the engine cause I wanna be able to move it around the garage by myself yet.
Once the engine ideas are done I will start browsing ideas for suspension and brakes and all that....not a big concern..good parts equals not a waste of money. Ya always want great handling and stopping power, no matter how many ponies under the hood.
One other thing, what do you do when you want to go over the transmission horse, copy Ivan's setup. Is there any other options for the drivetrain.
I read in my import tuner mag that a guy so called "Bastardized" a skyline and an SR transmission to get what he wanted. Anybody ever try that with the KA.

Re: (Diggity240sx)
Lemme tell ya, once you go turbo, there is no going back. You W I L L get bitten by the boost bug. If you want 300rwhp for a DD, you W I L L want more for the track or for those times of 'need' or a 'fix'.Diggity240sx wrote:Are you pretty satisfied with that power or do you want more.....

I would say getting the Advanced Rebuild kit they offer would be a great place to start. Not to mention, they are offering it at a slight discount right now I think($1,685 shipped?) Like I said before, 300rwhp for a DD is awesome, but there will be times you will wanna throw some race gas in it and crank up the boost.Diggity240sx wrote:Would say it would be worth getting the rods too if I am doing the pistons and everything else.

Again, get the AMS rebuild kit if you want all the parts, and no headache for a solid block. The AMS Sportsman rods are supposedly fine up to like 500 hp or something like that.Diggity240sx wrote:My main concern is that I build accordingly.

I wouldn't put an e-bay exhaust manifold on it. But someone will have to chime in on this one because I'm still undecided on one myself. If you want reliability, and longevity, do NOT get an ebay mani unless you plan on re-welding the piss outta it.Diggity240sx wrote:Adding an ebay mani and fmic and Megasquirtin' it.

I know alot of guys running stock 5-speeds with name brand clutches and they are pushing 400+whp. There is a write-up on here someone that say's if you want something that wont snap your transmission, get a sprung hub clutch disc. This will keep the 'impact' effect away/out of your driveline.
Whew, that took me a few minutes to do, so hopefully it helps!
Re: Somebody be specific cont.??? (Diggity240sx)
thans for posting this, It was helpful for me too, Im not sure why you say that the original thread didnt belong on here. I figure all of the questions that I ask are really reltive to my soon to start project as I, just like you dont want to have to go back into a motor.
eazye2000 said it right. you will get the boost bug. Boost is Very addictive, but after having a turbo scare once, I decided that I didnt want to risk having to replace the most fun part of the car, so in the next build I am opting for a tune that will remin the same for street and any track use. the last car I build was built with that in mind and I like it that way because it leaves it simple.
As for the transmission option, if you are looking for more power, I know that there is some custom Z32 and skyline transmission swapping going on. Somebody else will have to chime in but I think its mostly as simple as a bell housing and input shaft and ?mounts? these trannys are supposed to be stronger than the KA/or SR transmission. so there are a couple of people that go to those with higher power setups.

Man, I don't know what we would do without this guy!WDRacing wrote:I changed the title for you. It helps if its related to the actual topic. That way when someone uses the search function, this thread may comeup and assist someone else two years from now.
WD
But the only thing left now is the transmission. I have no input on that, as you will have to search or hope someone will see this thread that has done a transmission swap like that. I would say stick with the stock transmission until it breaks. I know that sounds kinda harsh, and most people probably wont support that comment, but the stock transmission's have been pushed well over 400whp with no problems. More often than not, they hold up just fine.

Re: (WDRacing)
WD as always man....I tell ya I see your name on the post I read more than anyone. It seems like every aspect of this car you have been there done that, and yet you still jump on here to help all the rest of us. I swear I think I look for your post under topics because thats usually a good solid place to start. Everybody else had some great points I am just throwin some respect out there for WD.
Well The info was awesome you guys totally help me decide. I am going with the full build, because I am always wanting to one up myself. Those transmission swaps that were mentioned sound pretty sweet I will have to look and see what others have done. Even though I will prolly never do it. IDK it just seems like since I have been on this forum I remembered how to read and actually enjoy it.
Since mine isnt a daily driver I do want the full build. I would like to take it slow though. For example, Whats a good HP range to start at. I mean I dont wanna do the full build and run at 15psi and totally kill myself. I dont really wanna buy a small turbo then have to upgrade it and retune. I would like to possibly get the gt32 or35. I have heard good things and people seem happy with them. I am not toally sure but isnt the minimum like 6 or 7psi. See the problem is that I dont really know how much different just the build will have on the car. Lower compression piston and bigger valves is gonna add some power but how much, then throwing a honkin turbo on. What would I be lookin at powerwise. A ballpark number is fine. Would that put me around 280 at 7psi? I am waiting on my boss to send me this computer dyno sheet to see what each combo of block would do. Then different size turbos. I just want to still be able to drive the thing when I am done. Not as a grocery runner or nothin. If I did it would have to be something quick...lol.
You guys have helped me out alot. I think I will have all the bodywork done before I finish the engine but who cares....makes it easier to paint a rolling chasis anyways. As I learn more I will try and help out some of the other guys...when it comes to finding body parts and such I can certainly help out. Xbox's I can help. Body and paint I know enough about. Let me know if you guys need anything I can find the answer even if I dont know it...lol.

Re: (Diggity240sx)
Well thanks Shuan!!! I love the Nissan comunity and I love boost. Add the two and you get a really good combo. When I was a noob to turbo's, I was always afraid to ask dumb questions. I don't want anyone else to go through that. Everyone is a noob at somthing at some point. The way I look at it, if I have the chance to help somebody out then why shouldn't I?
If you do go with a stock transmission setup. Your most important decisions will be clutch and flywheel choice. I recommend getting the clutch and flywheel from Spec. Also, you're going to want to run Redline Heavy Wt transmission fluid. Then you will be just fine as far as transmission's go. Assuming you're not launching repeatedly on slicks. Then I can't say for sure how long she'll last.

Re: (turbonissan)
I havent built yet I am looking into the build. I have decided to just get the kit from AMS. I like that it is all in one. I want the .20 over pistons with the 8:1 ratio...lower compression. I am still deciding on what other things I want. Wanna test the dyno and see what numbers come up. Hey Eazy as always man big help. Hey you mentioned the ringlands....I searched the forum and only found general q's and I was wondering if the new pistons and rings would be a good fix right. Thanks

Re: (Diggity240sx)
If you get any type of after market piston that is forged, you will more than likely eliminate the weak ring land problem. I'm going with Arias pistons myself and should be ordering them in the next week or two.

Re: (eazye2000)
Lucky you I wish I could say the same....My truck is in need of some suspension work and I figured since I would have it apart this time do some other crap too. And to think I just had the driveshaft out replacing the center support bearing man that sucked, but its done. I have my 240 in the garage but cant get time to get to it I started removing the driver side body lines though. I hope to get to the engine soon though. So is your 240 working now or just sittin without the pistons.
