I'm New Here And I have A Simple Question Thread, (No Flaming Allowed)

[gshdrift879]

Appreciate it d!ck. I have never even heard of BRM but great sounding exhaust. Thanks.

[megaderk]

whats the differential do?what kind are there?whats the difference between them?and i hear alot about welded diffs. what do they do?

[megaderk]

whats Super Hicas?

[Speckid14]

Is it ok to use a "used" crank on a KA24DE-(Soon to be T) that will be making over 600hp? What should be done to maintain safe operation, but not burn a hole in my pocket. I don't really want to spend the extra money to do more than knife-edge. Of course all bearings will be checked and all that good stuff. Thanks for your help!

Also if I get an Underdriven pulley like the Orthodox, ASP, or ATI, does that affect reading timing at all, or does the company make changes to compensate for the smaller pulley? I know if effects belt size, wouldn't that effect when engine accesories engage and disengage?Thanks again, its really appreciated!

A differential transfers mechanical energy from the driveshaft to the rear wheels. It is also known as a "pumpkin" and is found centralized in the rear of the car.There are many kinds of differentials, but the most common (from a factory) are: Open, Limited Slip (through some form whether it be viscous, clutch, helical, etc), and posi-locked.Welded diffs are basically welded to become posi locked. They make sure that both wheels spin at the same rate NO MATTER WHAT. This means that your turning goes to absolute crap, but you can kick the *** end out like nobody's business. They are also cheap. For these reasons, they are popular in the drift crowd, but should really only be used for drift only cars.

whats Super Hicas?

Nissan's version of all wheel steering.

1: If you are building a 600hp 4 banger, you are going to have to spend some money. Yes it is ok to use a used crank, but you absolutely must get it checked out 100% by a machine shop before you do. If they say it is ok, then it is OK.

2: No, it doesn't effect timing. Timing is driven off the distributor, not the crank pulley. The undersized pulley merely effects the "gear ratio" between your accessories and your motor. Using an undersized pulley will not spin the accessories as fast as a normal pulley. It will not effect when they engage and/or disengage.

Think of it like this. When you ride your bike, you have big and small gears in the front, and big and small gears in the back. If you switch to a smaller gear in the front, it will be easier to pedal, but you will not go as fast.

so the 240 has super hicas?

and whats the limited-slip do compared to an open?

1) Yes, some 240SX's had Super Hicas. It was a relatively uncommon option, though.

2) With an open differential, if one wheel begins to slip, additional power is transferred to the slipping wheel. Thus, if you lose traction, it can be problematic to regain it.

With limited slip, the general idea is that it transfers power from the wheel that is slipping to the wheel that has grip. Depending on the type of LSD you're talking about, this can work in different ways with different trade offs, but in general, you get better traction and grip with a LSD.

For anyone who might know, this may be a dumb question but what does the Nissan super hicas exactly entail. I am not at all familiar with any type of four wheel steering other than the fact that it exists..but having never driven one i always wondered what differing handling characteristics would be b/t a super hicas 240 and say a standard rwd. Would one drift better than the other?

High Capacity Actively Controlled Suspension, the super part means it is run by an electric motor instead of the steering pump. It includes speed sensors and a seperate control computer to determine direction and degree of turn. My understanding is that super hicas is actually bad for drifting, because the rear wheels would be turning to help you corner better instead of losing traction for the drift. most drifters disengage the hicas system for drifting.

Appreciate it Warped161. Main reason i was asking was because i saw a super hicas s13 for sale and became curious. Thanks.

Here's a quick question how much does a ka24de engine rebuild cost ???

[alfsnissan]

Ok, Just letting everyone know, I have been having some problems, I got it worked out. (Mass Air Flow) I just have a few more things to do but 1 down and counting. Thanks everone.

[thouster]

I got one of those cheapo ebay shifters which works fine and stuff. But about three weeks or so after putting it in, the plastic thingy at the bottom of the shifter warped and came off. So I was wondering if there's a place where I can buy that plastic thingy.

[Warped161]

Here's a quick question how much does a ka24de engine rebuild cost ???

my SOHC cost me 1200 DOHC shouldn't be much more

Thouster you can go here and buy the bushing or get a brass one from cusco for 40 bucks. the stock one is a few bucks.http://www.courtesyparts.com/b....html

[jbquick]

Just bought myslef a 90' 240sx and i would like to know if anyone can tell me how much a head light motor is gonna cost me?

248 brand new from nissan, check local junk yards or post here in the parts needed section.http://www.courtesyparts.com/b....html

cool, i tho it was more expansive, Is this rebuild making the engine like almost brand new ? well does it makes the ka24de ready for turbo ?

[asko2k4]

hey guys. i just did the silvia frontend swap but my one of my headlight bulbs is out... major headache!!! where can i go to buy the bulbs?

[Warped161]

Mine had all new internals, oil pump, valve assembly, timing chain and honed walls.

[mastashake]

Hey guy's I have a 91 s13 and I'm about to buy my swap. I'm wondering if I should get a s13 blacktop or a s14 sr, which would be better for 300whp? oh and does a s13 exhaust fit a s14 sr?

[popi-dude]

how many psi were you pushing in it with those internals ?

[Warped161]

Stock SOHC ka no boost, not yet anyway.

[popi-dude]

how much would you boost indead ?? with new internals ka24de like mine ?

[Warped161]

There is alot of info on here about boosting the ka's, you can either peice together a kit or buy one complete. As to the amount of boost, well thats under debate but you can push a decent amount. I'm aiming for a low of 6 and a high of about 12.zerothread/226410 start here.

thanks for helping out the new members, apreciate it I'll try to find more info by myself

[PapaSmurf2k3]

If you are going to be rebuilding your KA for boost purposes, you should upgrade at least the pistons while you are in there. Stock pistons are the weak link for KA internals when it comes to boost. This of course depends on your power goals. Anything past about 270 or 300 whp and you are DEFINATELY going to want pistons for reliability purposes. Some stock KA's have held up to 400ish WHP, but they are lucky and have done some great tuning. Forged pistons give you a little wiggle room.

Past about 400 whp you should think about getting forged connecting rods as well.

My DOHC rebuild cost me about $1400.

my goal is to get about 200-250 hp to the crank.. so i could only buy a t3 and drop the whole thing into the enginebay ?

so if i understood, the weak point of the KA is the pistons ??how much does it cost to change them 2-300 bucks ?

would a 250 hp set up with new pistons would be fine ? or i'd have to change valves and some other internals ???

[megaderk]

whats the difference between the KA and CA engines?

and what was the HP for the stocl KA24E?

[jakums]

ok so i posted something on turboing my ka24e motor. looking to make 300-350 hp im also thinking on doing forged internals is this a good set up

cp 8.0 pistons 500$turbonetics t3/t4 50 turbo 745$universal turbo piping includes intercooler and blow off valve 250$APEXi SAFC-II piggyback 400$wideband plx m300 350$jdm ka24de turbo manifold 150$greddy B spec 2 boost controller 120$tial 38.mm wastegate 305$

is that any good? Is there any was i could save a lil more money?
