I should add that some of the purchases I am looking at right now are drivetrain related.

I am not certain but think I may end up going with a Spec Stage 5 Cutch and Aluminum driveshaft for extra measure.

stage 4 an 5 are pretty hardcore...

why not a rb20/350z clutch setup instead? just as much torque capacity without the unsprung hell the 4 and 5 will give you

Probably because I already bought a lightweight KA Flywheel... :/

I probably should have waited but the deal was too good.

Look at south bend as well. I have their Stg 5 (475 lbs ft) and it's easy to drive with no chatter.

love my white bunny could easily be upgraded from the cheap s*** I used to a 280zx turbo aftermarket clutch, still use the 20lbs flywheel and have a lighter than stock setup with the alu ds and an alu crank pulley. I think the 280zx t stocker can handle some a**(if the cheap white bunny(d21 clutch kit) is supposedly good for over 300ft lbs...)could save some money for other ish and have a bad a** daily drivable clutch...

this goes to you or wd, I'd honestly like to know just what a white bunny can throw down.(today I did a light clutch kick and had 3psi just reving the motor to 3500 )

Man I don't know about that. I've always been a believer in Clutch ratings because it hsn't failed me yet.

Every aftermarket or OEM replacement I've used was pretty dang close.

I'll be using a fully lightened drivetrain (Crank pulley, Driveshaft and Flywheel) but I would't give too much room even with those.

I have seriously considered these but I have some reasons why I am not using it.1-The cheaper, lower power rated ones are T25 flange.2-The T3 flange ones are expensive3-They are both water and oil cooled4-They are external WG, which is fine but I'd prefer to do this internally.



Really it's just out of my price range to drop $1200 on a turbo.I am certain I can find what I am looking for in the $500 range slightly used.

godchsr I just dont know the rating search white bunny and you could find out, using the 280zx turbo clutch (aftermarket) on the d21 flywheel would let you hold 500 plus most likely. The stock d21 clutch can let a 4cyl pull a 8000 lbs trailer.... I've seen it. I'm sorry but I'd take a larger surface area any day

Negative. Just source the parts and bolt them on- at least that's my understanding, just like the rb20/350z setup

Actually its a little more involved, you have to knock a brass pin off the crankshaft And let the flywheel grind the dust plate or you can cut it yourself while you have it off the car like I did. The dust shield had to grind maybe 2 seconds once I cut it, but more if you just put it in. It barks 4th just dumping the clutch and the flywheel I bought was 20lbs IIRC and could easily be lightened down to 16~18lbs or if you have a nice budget get an aftermarket d21 f/w or even a 280zxt(supposedly the same bolt pattern but I cannot confirm this as I have no experience with the 280zx stuff)I spent a total of 180ish for the whole thing, clutch kit /fly wheel I think I even bought my rear main with that price

What's the weight of the D21?

Can it be from any D21 or only a DOHC D21?

Because I found a few stockers on Ebay for $50 which leave enough money for the machine shop to grind it down for weight savings.

so long as its a ka d21, I used 93 as that was mentioned in the white bunny write up on here.

you will also need 3 more pressure plate to fly wheel bolts, making the total 9. I guess you could use 6 but 9 drilled and tapped holes = 9 bolts to me, on something as important as a clutch. I have 0 complaint and the overly soft pedal has gained a little firmness to it and engagement is at the top bout a half inch or so in, maybe half to an inch IDK maybe I was used to the heavy dutyness of the zoom pressure plate :shrugs

I'm definetely going to look into this and if I can lighten that flywheel a bit I'll probably do it

I dont see any reason you wouldn't be able to lighten it, you can do a stock 240 flywheel down a couple pounds. I just dont like the idea of a friction surface that can wear out, I know a stock flywheel can get burnt or have hot spots what have you.

Minor change of heart here concerning my turbo selection. I've been talked out of using an internal wastegate for this. No big deal and it probably wouldn't make a big difference but:::I am going to use an external WG type turbo now.

Externals are far better then internally gated turbo's in almost every way. From exhaust gas flow through the turbo to the ability to vent exhaust pressure far more efficiently. Running a big external also allows you to use a smaller exhaust housing AR without worrying so much about final flow numbers and too much restriction.

i have heard that the internally gated turbos arent as good... i assume that its because at higher boost the wastegate wont let enough air to pass through it. is this right?

bingo an external can let the air out much faster due to it physical size. I think internal guys can bore the hole some and use a larger flap but it is still mute in comparison IMHO. external can get as big as what 60mm?

edit its not that internal are not as good, they work perfectly fine, but external does a better job.

I actually had a dream about this race last night! lol

It was extremely vivid and realisitic.

I had a perfect launch and WD was a step behind but going into third he pulled on me.Here's the kicker, somehow I altered the dream because as I realized I was losing magically a Nitrous button pops up on my steering wheel (for some reason I am certain it was a 60 shot LOL)I hit the nitrous and win by a nose.

hahahaha

Anyway, I won't be using nitrous but maybe it's a sign that I should keep my options open because I may be on the verge of losing by a nose.

I never nail down a plan until I'm about 3/4 of the way done. I have so many crazy idea's floating around upstairs dude...it's impossible for me to stick to any one plan. But as far as N2O is concerned, I'll have to use it in order to actually be competitive. His budget and parts are going to be quite a bit more/better then mine. But I've never let things like that stop me

Nitrous is the great equalizer

You keep saying that like I'm rich or something! Don't try and play this down like you're an underdog from the get-go.

Dude, I swear to God the only reason I have a nice house is because I don't have any car payments and I buy everything with cash... ZERO credit card debt!

So, having said that I am in the 'black' by quite a bit every month but I won't frivilously be spending money on this project. I am designating payments... buying one piece at a time.

Heck I even had to buy a second S14 just to get back up parts AND part it out to help with my cash flow. It's like a second job (see my sig link)

I don't condone drug use

Yes no debt is the bomb! The only 'debt' I have is my house and I bought that from a guy going into bankruptcy for $80,000 below the appraisal I had done. I have a 30yr loan on a fixe rate of only 4.5% You heard me right FIXED @ 4.5%!!!

Also my brother lives in my basement SO every month I take his 'rent' and throw it towards the principal... So my 30 yr loan just became a 7.5 yr loan We still only pay $100 more than when we rented too.

I know I'm being a prick but the truth is that I am proud of how we conduct ourselves. My wife and I have no college education, we're both in entry level jobs BUT because we are hard workers and don't spend frivilously we are living in good times.(I'd also like to take a moment here to thank God for the blessings He has given us)

Anyway... that was ALL totally off subject:::

I plan on using WMI or WAI.

Your EMS is more $$ then my entire budget. So yeah, I'm the under dog from the jump. I'm not playing that card as an excuse, I'm F'in good and will probably be faster then you for far less $$

My wife and I paid down a large portion of our debt as well. We're down to one car payment and the mortgage. But I have 2 boys, 14 and 2. They are expensive That and I've been laid off for like 6 months. Not that I'm looking for a job anymore. Being a S-A-H-D rocks...wouldn't change it for the world. When we move I'll open up a small time tuning shop probably, who knows.

I'll be using sub-injection for sure, as to what fluid I use it will either be meth, denatured alky or a homemade mix of toluene and water. Similar to what the F1 guys use for fuel.

Nitrous has been in my plans for years now. IMO, nitrous allows you to build a low lag fun setup while giving you the ability to shave 1-2 seconds at the track.
