KA-t 1/4's

[95_240sx]

They are mucho fun around town too, you can really make them hookup nicely.

[TurboKA37]

how about those vids? eh

[95_240sx]

Blah, We got too drunk last night and didnt get around to getting them done. Im going to get them tonight, although you can only see my launch and about to the 1/8. Ill get some better once next sat night (12.2 is the goal)

Rick

[TurboKA37]

cool the 1/8 is good enough to satisfy my needs

[95_240sx]

Blah, Friend capped out on my tonight, Ill hammer him tomorrow.

Watch that lightened OEM flywheel as you get faster ... I've had 'em disintigrate and it ain't pretty! IMO, a good investment would be to fabricate a scattershield.

[TurboKA37]

i saw a deal on a custom lightened flywheel for the KA. h claimed 8.5 lbs. i plan on a turbo and to push at least 250 rwhp along with a more agressive clutch. do u guys think 8.5 lbs. is too light and will not provide enough inertia for a daily driven car?

I don't think it would be bad. I think once you get below that it starts getting bad though. In my Celica GTS I had a Fidanza lightweight flywheel that weighed about that, maybe slightly less. It's not harder to drive per se, but you have to use a different technique and launch a bit higher and watch it or it may stall coming from upper rpm to idle quickly. It makes it harder to drive and you don't always want a car that's harder to drive in times like commuting and stuff like that. But definately driveable if you want to put the work into it. A pain IMO, so I didn't opt for one with my clutch install.

I would rather go with the lightweight driveshaft, although more expensive, you don't have all the downsides, it's more like installing lightweight pullies.

[fritts]

95, how do you like your phantom grip LSD. Did installation go ok, does it require much maching of the gears? I have looked at either doing the phantom grip LSD or the VLSD, as other than that I'll be paying 800 for any other LSD.

[SHiFT]

Whats the difference between a VLSD and a phantom grip LSD?

[iliketocrash]

isn't the phantom grip just an extra spider gear that you put in the diff. or something? And i think that it keeps both wheels moving at the same time at all times, as opposed to the vlsd where there is a viscous liquid that cause one wheel to first have to break loose a little before it causes the other wheel to lock into movement. I dunno if this is correct or not.... i'm just kinda stabbin in the dark a little... or at least it might be dusk.. or something.

[:: orion ::]

Whats the difference between a VLSD and a phantom grip LSD?

A VLSD actually works...!!!

Hehe... :pface

Seriously - IMO, why bother with a 'patch', or a band-aid solution for $300 when you can get OEM reliability and functionality for the same price or less???

i.e. a J30 VLSD can be had for $250-300...

And the Phantom grip isn't an extra spider gear or anything - It's 2 hardened steel plates with a large spring in between them - You place it between the spider gears and it pushes out on them, attempting to keep them the same speed.

But the one flaw, IMO, is that it's designed to work based on friction...but it's surrounded by gear oil designed to reduce metal-to-metal friction!!!

I could see how it would *marginally* help in a straight line, but in ANY situation where one wheel can start spinning fasted than the other, there is NO WAY where this thing can slow the one down and lock the 2 together - It's not strong enough.

My $1.02...

Orion, Have you actually used a phantom grip. I want to know someone's opinion that has used one in our application. To see whether or not its viable. I would much rather have a locking type of diff than a viscous due to it takes slip in order to actually create a locking diff on a viscous type. The only other options just cost to much. There are plenty of extra open diff pumpkins out there for really cheap so if you do destroy one so its not a big deal.

[scotty-2-forty]

I used a sponsored Phantom Grip in my ProStock race car for the 2000-2001 NIRA and IDRC seasons. WrighTouch Racing also uses it in contingency. Marginal is not really a word I would use to describe the units benefits. PG virtually "eliminated" torque steer in both drag cars (FWD). Understandably, it may not be cost efficient for the 240 since the VLSD can be had for cheap , but the only alternatives for the FWD Neon and Eclipse was to either build a spool or use a Quaife LSD. Both of those cost in excess of $1200. Also, check out the testimonials on http://www.phantomgrip.com from professional drag racers and rally drivers, FWD and AWD alike ... again, I'm disagreeing with the term "marginal" and the NO WAY comment. Our all motor ProStock Neon delivered 225whp and the WT ProFWD (now Pro 4 Cyl) Eclipse now makes 700whp ... big HP to back the PG. I realize the comments are based on the RWD 240 ... but this is my 2 cents, coming with experience to back it. PS - I love my 240 ... never going back to FWD

[:: orion ::]

fritts:

I have not...my opinion is speculation.

But remember, it IS NOT a locking-type diff. It acts just like the viscous units...but backwards. It tries to keep the axles locked together until they need to go different speeds, instead of locking once slippage is detected like the viscous - Same idea, except the viscous units can reel in the tire that is spinning faster (as one spins more, the viscous fluid heats up and locks the 2)...whereas the PG may be able to hold them together IF they are moving together (both wheels same speed) to begin with (i.e. in a straight line)...but it one was going faster (i.e. around a long sweeping corner), it's couldn't make the 2 match speed. NO WAY can it have the strength to do that...

scotty-2-forty:

My point is exactly that - In FWD application where the only close solution is $1200, why not go half way and use the PG...especially only for drag. It's better than nothing...

But when you can get the VLSDs for the same price, and they will work in drag and auto-x/drift...again, why not.

Again, this is just my opinion, and I could be wrong...but it does not make intuitive sense.

i have a 97 auto with intake,underdrive pully,and exhuast, i was thinking of getting a nsport turbo kit and they claim 240hp at the wheels is this acurate, and what do you guys think i will run in the1/4 with the nsport kit?

[95_240sx]

Ok, the PG is a good unit, but only if you can break the tires loose together (i.e. already moving in a straight line) and pop the clutch to get them spinning, which works good for me. Also, if you can get them broke loose together and are decent at keeping them under power while drifting, you will always keep them together, although they frown upon drifting through the burnout box at the dragstrip.

There is no machining of gears required, you just tap it in there and then slide the pin back through the gears and youre done. Mine would have gone that simple, but when we started to put it in, the clips holding it together got knocked out and the entire unit came apart at light speed and we were searching for the yellow springs forever.

My next project on the car is to get my wheel hop problem fixed and get a TRUE LSD in the back.

As far as my fly wheel, It still weighs a lot and wasnt lightened as much as it was resurfaced.

Rick

EDIT: Donovan, use the search button, theres dozens of threads about your specific question.

[WDRacing]

I agree with Orion on the VLSD, Its worth the money, especially if you can get a VLSD from the J30. I've seen lots of people try to short cut the VLSD, I've even helped weld a set of spider gears together for full time Posi.

Rick, just becareful with the OEM flywheel man, I'd hate to see you roll up in a wheel chair cause your legs got cut off by the flywheel exploding.

Lightened flywheels are ok, I'm going with a semi light FW myself, only because I want a forged unit balanced with my rotating assembly. The lighter FW's make it hard to keep the RPM's up while racing, IMO. If your motor lacks the torque to get your motor up to speed, HONDA, then its not a bad option.

[SHiFT]

so why didn't all car makers just put in a LSD of some sort in the first place on all cars? Why even put in an open dif in a car from the get-go?

[:: orion ::]

Cost.

It's why car makers do a lot of things. Well, everything.

Later - Brian

[iliketocrash]

i don't think its so much as cost, as them wanting another option for you to over pay to have. :pface

[SHiFT]

Alright so how exactly does an open dif work and why would it be so much cheaper? I know when I floor it sometimes the left rear tire spins tons faster than the right side and provides the real power. What causes one side to connect all the power to the ground and the other side just a little bit?

[iliketocrash]

what kind of quater mile time do you think i could get with the nsport kit any help or advice would be great!!!!!!

ummm.... shut up? First off, start your own thread, don't hijack others'. My advice, use the search button. If you want specifics then find out what kind of turbo nsport uses in the kit and then compare the turbo setup they give you w/ other people's who's setups are similar. I really don't believe anyone is gonna spoon feed you the info you're looking for. Quart mile times vary based on more than just horsepower. Traction is a big one and learning how to do a proper launch is another. SO FIGURE IT OUT.

[donovan]

sorry for trying to hijack this forum, i just thought that since you guys know more about the ka24de-t , and that you all drive and love the 240sx such as i do,that maybee you could take 30sec out of your day and help a fellow 240 owner by answering 2 small questions.and if you bothered to read the questions you would realize im looking for your opinion not your sarcasm.i guess ill have to go ask some honda guy! thanks for nothing @$$ #*!&

[ROB240]

If you have a question to ask how about you just start a new THREAD in this FORUM instead of hijacking someone elses THREAD. Maybe you should take 30 secs out of your day to use the search function to find answers to questions that have already been answered. If this is the kind of atitude you have being a new user to a forum, dont let the door hit ya.

Look, you didn't read my post did you? There was some sarcasm as well as good info. Also, if you'd calm down and stop whining, you wouldn't make your ignorance so obvious. Anyway, i said you were trying to hijack this "thread" not "forum", there is a difference. All you have to do is click the button that says "new topic" and then post your question there.

edit - well ROB240 beat me two it but now at least you should get the point donovan

[SHiFT]

now now kids play nice

[scotty-2-forty]

Let's see ... easychair - check, popcorn - check, beer - check, remote - check, shoes off - check, feet on the table - check, ... WHAT THE? HEY, THIS IS NOT COYOTE UGLY! ... <<click-click>> ... WHERE'S FRIED GREEN TOMATOS?! ... <<click-click>> ... I NEED A CHICK FLICK!! ... D@mn, nothin' on TV; guess I'll stay here. :fight

Really, this could all be avoided if someone would take 5 seconds and answer the question. Question answered, people happy, life goes on. I'd like to think that treating a newbie like this should be a no-no ... don't we want more people to come to the boards? Or is this some sort of click I wasn't informed of? Now kiss and make up! :cuddle

Donovan, there ARE quite a few variables missing (as was mentioned) in your question. But a beginners software which is really easy to assist in guessimating can be found at http://www.virtualengine2000.com. It's a free download and you can input info such as vehicle weight, HP, TQ ... and it will calculate all kinds of useful information for estimating. I'm sure there are others. Hopefully, it will help you.

[donovan]

didnt mean to be snotty but unless im retarded this forum is for 240sx owners to talk about there cars and "share" info about them or to just plain help someone who doesnt know!no hard feelings here.scotty what kind of turbo kit is that in your picture,and does the nsport kit really make 240hp at the wheels as claimed.

[HolyShiznit]

Go search the specs of the Nsport kit........or do search for people that have used the Nsport on their 240 here and on FreshAlloy. We aren't trying to be rude but there is at least 8 times a day where a n00b asks a question like. "If I use this turbo and one of them thar intercooler thingies....will I beat Corvettes?"
