pros/cons of going turbo KA or SR20?

[SinceByMan]

why don't you want to keep them dry sump? I'm seeing more pros than cons w/ dry sump. . .

well, with a dry sump, the biggest con is complexity,

this is from an article in HotRod magazine which explains how to build your own 357ci 650HP Chevy SB2 small block...with an 8,000 RPM redline...and it runs on pump gas

"the dry sump system has a belt-driven, multistage pump bolted to the front of the engine that is essentially four oil pumps spinning on one shaft. Three of the stages are used to suck oil and vapor out of the engine and one stage is used to pump oil from the large cylindrical oil tank into the engine"

plus, the belts can break easily if a rock or something gets in there...but dry sumps can be worth 30-40 hp

[karay240]

so, you're saying that you'd rather have a oil pan that sits only inches away from the ground? I've heared of people blowing their motors from dented oil pans in non-lowered cars. How much worse do you think the chances are w/ a lowered vehicle? Also, when was the last time that you're belts broke b/c of a pebble?Not only does a dry sump system give back some hp (not sure about 30-40...may be in a domestic), it also allows you to mount your motor lower and will lower the center of gravity quite a bit. . . this lower center of gravity may not be too evident to a majoroty, but will also allow more freedom in designing a turbo mani.

As long as you got a oil pressure gauge, (besides the fact that it is more compliccated) I'm not seeing the negativities associated w/ dry sump systems. Nothing that can't be remedied with a oil pressure gauge with a warning light.

I'm not saying that I'm going to be doing this mod tomorrow, but it is an idea that I've been toying w/ for some time now. . .

Thanks alot for your reply. I was actually giving up on a response. lol

Going sr is ok, But you going to pay out the same if you turbo your KA. I have a 92 KA-T 300Whp with stock internals. Do have several up grades. Sr needs some mods to produce hp; ECU upgrade, injector, Ect....

[barrigas14]

Sr is a great engine but prices are terrible. 3100 for a local engine and 2600 for a black top and 2500 for a red. that is w/o shipping. plus all you get is stock **** and maybe an s/m intercooler that may or may not work.

for 3100 + new turbo and intercooler + bigger injectors + fuel thingys = ka w/ forged rods, pistons, bigger turbo, injectors, just everything for about 400rwhp. that is why i am going KA. for the money you just get more. and there is ALOT of support for the KA now.

[dabum]

GO KA!! i heard that tha sr20 puts out a max of 250rwhp on stock fuel system after that u hav to get the bigger injectors nd maf, why would u want a motor that costs so much just to waste more money upgrading it again once u have it, why not just get all the new more reliable parts listed above like barrigas14 says

[oldsoul]

Id like to open a new can of worms. What about supercharging the engine. No lag, no need to rev it to the moon, and last but not least.......that would really be different. (oh yeah thats what im lookin at doing to my car)

supercharging would be good for when you need the power instant and what not. like tight road courses and autox...maybe the drags but those aren't my thing. anyways problem though is the modification. one guy in Az was saying he can fab up a SC system for like 2500. too much for me. plus you'd only be running 7lbs of boost. i don't know much about the SC and i know that getting more boost is related to the pully sizes or something of that nature. unlike turbo where it is just a knob away.

I agree, but im not gonna bash teh engine it honestly costs more. Its no joke.

[dabum]

this thread is never going to end.

no this thread will never end, the Battle of the KA-T against the SR20, mainly because ppl have different opionions and because alot of motors have great potential, i think its all basicly a question of how much your going to drop into the motor and thats that, each motor is better at different price ranges dumped into it.. this is a never endin argument and but as long as its goes on and some sr20 guy says its better then the ka-t, i'll be rite here to post.

[candela]

so 95+ ka rods are really a lot stronger than previous years? What exactly are the differences in the s14 KA motors (internal wise)? I know a guy here in AZ (ty) did ~340whp on a bone stock (cams) KA24DE from is s14 Kouki...

I am all for trying a KA-T settup (done sr already), and am really feeling sil80drifter and Barrigas on teh whole custom settup thing. I am very confident that I could put together a nice reliable kit (with tunign ofcourse) on my 130k KA for less than $2,000.

BTW- this is not any argument, I am going KA-T after an SR. I absolutely love all teh qualities about every nissan motor. I may even try a turbo sr20de later on to. Stock SR20DET parts are becoming very plentiful, and I'm not one to waste :p

Can anyone off the top of their heads or from their favorites or something, link me to some cool inexpensive KA-T settups? I am really looking into what everyone is doing for fuel/fuel pressure and ignition timing. Thanks!

*cries tears of joy*you get me! you really get me! oh i never thought this day would come! *sob*

I got all my stuff from jim wolf technology, they will tell what you need and what kind of Hp you want, but will cost $1000 or more depending the Hp. KA-T running great.

[jdmfreak]

$1k KA-T? Please I wanna hear more.

[gc8936]

sorry, just for equipment to support a KA-T 275- 300Whp with stock internals, Ex: Ecu upgrade, injectors, MAF, Fuel rail Ect....

[jdmfreak]

Oh I was about to say. Thats the cheapest setup Ive seen. If only it were true...

[D-UNIT]

Ha Ha no kidding!! My turbo alone was $1000 LOL!!

[gc8936]

How many 240 is out with KA-T and what is the HP.

[sil80drifter]

there is a separate thread for that.

This thread will end if I post nekkid pics of myself! wooohoooo!!!!!!

[Onizuka]

dude, obviously "cheap" is just a realtive term here. Is 2 grand a good chunk of change? Yes. But when compared to an SR, the budget KA-T comes out cheaper. Hence, the term "cheap" being used.

How many SR's have your built? How many KA's have you built? Either give me the price breakdowns of all your projects or stop speaking out your asscrack.

Your sig is just retarded, good job.

I want to see someone hook up a KA24DE with a restrictive cast iron manifold, a T25, a pea-sized side mount intercooler and then tune it for japanese 100 octane and dyno it on 91 or 93 american crap. THEN we will see how comparable they are.

[Onizuka]

Im freaking out, I love these damn threads, so many people are able to say facts about things that they have no clue about...

Nathan, post up your drunken nurse pic's ASAP, we need to shut this mother down

[jdmfreak]

Come on Nathan!!! DO IT DO IT DO IT!!!!

[dabum]

nooooo NATHAN DONT DO IT! FOR THE LOVE OF GOD!

[Nathan]

Oh come on guys, you KNOW you want to see Nurse Nathan!!!! The only reason I've never posted that picture is that I KNOW its good photoshop material, and I dont want to end up with that picture and then the word "FAG" in bold lettering across it floating around the internet for the next 40 years.

The main reason why I wouldn't want an SR is because of where I live (california) damn near impossible to get it smogged and if I ever got pulled over and was told to pop the hood there goes my car. My brother put an SR into his 240sx and has to register and get it smogged coming up real soon in like 4 months and has no idea how hes gonna do it

Krux--

First of all, welcome to the boards, man. Secondly, living in Cali, you'll be in smog hell anyway if you go and turbo the KA. Believe me, I've done a lot of reseach in this area, and almost any heavy performance mod on the 240sx is NOT smog legal. There are ways to get a lot of power out of the car LEGALLY, but I estimate that it would cost you about 10K, and then you still wouldn't be the fastest car on the road.

BTW, despite what others might say about dragging out old threads and posting on them, kudos to you for using our lovely "Search" button. After all, that's the only way this thread could've been found.

[240Knightrider]

there was a 240 on ebay with the sr that PASSED the smog test. Dunno how but he did.
