your kidding right?

He's been told the same thing 4 times already. He's not going to be able to comprehend it.

comprehension really isnt your friend is it?

for all I know, you have a single cam, you want power, dont want an sr, don't have a dual cam ka, don't have money, don't have knowledge on how to properly turbo a car, and you get upset when you hear sh1t you dont wanna hear. Everything that everyone here said has truth matter and probaly 10x the experience you'll ever have with boosted engines (or engines for that matter).

i dont have a whole lot of money to throw into a new motor

which ever is cheaper.

just an fyi... you gotta pay to play. You've just entered into one of the most expensive-est hobbies out there. You want reliability, stay away from turbos with your kinda motives

LOL

i was just checking for myself, i have a friend who works for nissan he will be helping me with most of it, and as i said earlier, i will be playing with it after i get out of school, i am just looking to keep it running in the mean time and was looking to buy a replacement motor.

from what i can tell the sr20 has an aluminum block and head, which is a big advantege over the much heavier iron KA's block, it is also aready equipped for the turbo which would mean less work when i actually got around to working on it. but thats not what im worried about. thats actually why i bought the car... and i would replace everything in the KA that would make it second to the SR with the exception of the aluminum block. and because of it's larger size should push more than the SR. and i am only wondering about that compression ratio. which after replacing the rods and pistons, i should be able to get pretty descent compression ratio's

here is the plan... buy a 2.4 DOHC motor.

buy some 90' SOHC pistons for it. forged steel rods. 95' DOHC head, i gotta look more into cams, and i would use the 91 ECU, cause it's obd1 and i wouldnt have to buy the damn obd2 interface to tune it. (cheaper) and then add the turbo. and im done. thats if i cant bore it out, cause if i can bore it out, i have to buy new forged pistons, which i'd rather do anyways. and then i would really be on top of a sr20.... k i found out what i wanted to know...

[mr2man07]

first, ask yourself, hey, do i have the proper tools and knowledge to remove the motor? me alone on my first engine removal took me 2 weeks (2 hours a day ) past 3 days ive been putting it off because my family was up here. i took my precious time because i dont have the money, so its a side project to keep me off my ***.

then see how much you have. a car isnt worth going into debt over, im flat broke after buying these 2 240sx's, but i should have $1000 these next 2 weeks so its all good.

in my opinion, a ca18 or an rb20 would suit you well. a ca18det will be easier as that was the motor that was originally in there, a rb20 takes a little more work iirc but still isnt as bad as an rb25-26

[fearlife87]

lol, i got tools tons and tons of tools. im not worried about being out of a ride for 2 weeks, my father has a car lot, im sure he will loan me something in the mean time. and i will have plenty of money after i get out of school. i am signing on with this company, they promised me a 5k sign on bonus and i just have to stay there for 2 yrs at least. not a bad deal. plus i wont be doing much of anything, computer engineering is a breeze. so mean while my buddy from nissan will be hookin me up.. im paying him of course, but he is a good friend, so i know he will do a good job. the funny thing is, it will look bone stock, lol. no one will expect a 300hp 240 lookin at it lool

[mr2man07]

the iron blocks are best for turbos

the 2jzgte, 3sgte, 7mgte, ,rb20, rb25, rb26, i believe the vg30 etc . a lot of turbo motors use iron blocks. all the motors above have all hit at least 700hp too.

[fearlife87]

yea, but i have to find something cheap and durable in the mean time, untill i finish school. i have actually comntemplated fitting a 350 chevy motor, or a 302 ford motor in it. i already have one of these, rebuilt, but i havent had it running since it was rebuilt. so im rather weary of putting it in, and it would need alot of conversion to make it work with the rest of the car, but a carb with sraight out hp would be alot nicer.

[drift donkey]

going for 400 to 700 hp on a ka your spend as much if not more than a JDM engine swap!

[fearlife87]

not really, i dont see how every one thinks it will be soo expensive

motor $180 - with replacement warrantypistons $500-$600rings $50other gaskets $50 1mm copper headgasket, not sure, im presuming 150 at most, maybe 200Boring and honing under $200then for now, thats about it.

it's right at 1000, and i will have better performance without a turbo than any other 4cyl import.

im getting free cams and ecu. and the head comes with the motor.

[dgms240]

ive got a dohc ka sittin in my garage... it has a slight knock, spun bearing #4, the head is fine and no damage to block at all (cylinder walls clean and smooth), but you can have it if you pick it up. im in myrtle beach by the way. [email protected]

[180fan]

you forget about a few other details. bearings on the rods and crank. on the ka I usually see the rods give before the pistons. So upgrading the pistons would be like getting better shoes on a person with toothpick legs and expecting them to win a 100m dash. balancing and polishing the crank journals is a good idea. you may want to look into coatings on those pistons as well. But if you're also looking to build more power, you'll find a wealth of power to be gained at the head. Then you start looking into some serious money...

No you won't. If you are building the engine to handle boost, then you will have to go with low comp pistons, which will suck monkey poo for NA.

[fearlife87]

i am building the motor for boost yes, and the head will come later when i have a little more money, i am just getting the bottom half done right, whil the motor is out of the car, so i dont have to pull it again, or well pull it out of my car period.

[mr2man07]

the ultimate motor swap for me (other than a rb26 or the 2jz) would be the 1uzfe lexus v8. im a huge toyota (and now a nissan) guy and i love the 1uzfe. whats not to like about a $300-800 32valve dohc v8 with 300ft lbs tq?

theyve already hit 1000hp twin turbo in supras and theyve just started recently swapping them in a little bit more at a time.

i had plans for my 90 240sx to get a 1uzfe but i have to get my 89 working for school
