boost_boy, 'over hyped' is correct. Yeah, I hate hype, but a good car is a good car. HP can only make up for 'some' of an inferior suspension design.just a for u guys that think power is everything... did u see the honda vs nissan challenge on supertuner tv ? Nissans had twice the power and some pretty elaborate suspension mods... and what happened ? All I saw was a few nissans flying off the course. lol

ca18det_boyI agree totally. nuff said. Bottom line. a 50/50 wt distribution looks good.... on paper. Those porches must really suck, huh ?

paul_s13sounds like your solution was "correct brake pad" away. No such probs with the v6tt s13, and guy drives it pretty hard.Your BMW big brake kits look interesting.Hope your old s13 went to a good home.What project are you working on now ?

OK, I guess I might as well put in my 2 cents.First off I have raced auto-x's in SR swap S13, SOHC S13, (similar weight balance SOHC had better suspension) I have also raced in well set-up ITR's and Subaru's and an early SE-R Sentra, Porche's, new Celicas, AE86's, etc. (what I am trying to say, is I haved raced all kinds of cars at all kinds of prep levels). Weight balance on the ITR is 62/38 (quite bad) however, the way you set the suspension up can make any car handle great. Throw a huge rear sway bar or heavy rear springs at a front heavy car and that thing will rotate too easily if you want. And everyone knows the ITR has the best FF suspension design out there. However, with bad weight distribution, to make it rotate well, you are going to give up some ultimate grip. But at the same time the ITR has the diff to pull it out of the corners nicely. A car with 50/50 distribution will be able to put the most power to the ground when neutral handling is desired. On road courses suspension tends to be set up a little toward the understeer side because it is easier to control. So on a road course, an ITR would be great. In auto-x you tend to want a little more oversteer so a 50/50 or even higher toward the rear will be the easiest to set up to go fast.

I guess what I am trying to say is once a car is set up right, any car has the potential to be amazing. The ITR is just easier to look good because it is so well set up out of the box for a road course. Personally I like a neutral handling car and with a 50/50 distribution that is so easy to achieve. I am looking forward to my CA swap. Now if I could just find my S13 under the 3 feet of snow it is buried under after last weekend.

All of you guys are pretty intelligent, especially when determining what audience a car company is targeting with a specific vehicle. I've concluded that Type R was built to target road warriors and auto-x junkies who saw the price of BWM to be not appealing for a car that they can have some fun in. To me, all the little honda cars are what today's low-budget enthusiasts are lusting for. Parts availability is a plus; and swappability is truely not out of reach.

"quest" it doesn't surprise me that you seen the nissan vehicles flying off the track either because I got 1st hand experience flying off a highway at better than 160 in my sentra and lived to tell about it. Nissan's have decent economical suspensions and was built more for the overall ride/power factor. Nissan's would derfinitely lose their appeal if they focused R&D on suspension refinements and not the big picture which is the total driving package to include Hp, Tq and appeal.

Driver skill and car set-up can make any car better than any other. End of story.

I tried many pads, Mintex, Ferodo, EBC, Porterfield & others and all had pad fade, I never had the fluid boil at all, I concluded that the only way was bigger front discs and when e36 m3 discs are cheaper than standard s13 discs it seemed silly not to try it.

Heres the thread http://www.sxoc.com/vbb/showth...ber=1

Heres a picture of the discs on the car

Heres a picture of the standard 280mm discs next to the M3 items

My next project has started with me moving out and trying to get laid as much as possible.

U obviously missed the point.The brakes and acceleration was mind-boggling... handling remained unchanged in my view. All with this "big" motor. My question? Then whats the big deal about weight distribution.

has anyone here swap the ENTIRE z32 brake system on an s13 ? hmmmmmmmmm
1 - I have raced one on a road course and I killed him. Now that could have been the difference in driving skill and maybe if the car had been in better equiped hands, the car might have done better.

2 - Weight distribution does matter. But it also depends on your drive train layout. You WOULDN'T want 50/50 on a FF car. You'd have mad understeer under acceleration, lift off oversteer, and couldn't keep the wheels on the ground.

Look at my mod list man. I have a complete Z32 brake system on my car and I've NEVER EVER EVER had brake fade. Granted I have X-drilled and slotted rotors. But I'm VERY happy with my braking system.

we're talkin about weight distribution in these cars, relative to engine swaps, aren't we ? I say its splittin hairs... even with a significantly heavier vg30dett I could detect no downside. Got it?There r lotsa cars with crappy distribution 'numbers' and way less power that will run circles around s13s. Fact. so what do distribution numbers mean... other than numbers?

your braking experience is consistent with my buddys', even tho he's heavier. So that may be the remedy, huh? - the whole z32 brake system.You've been busy with your car. Nice work in progress.

Well then why waste money on these expensive jdm motors? **** I am goin down to pick me up a 302 small block, and supercharge the **** out of it, apparently I can just do a good suspension set up and I will be able to work over type r's, s13's, porsche's and every thing else on the road. Oh wait. No. Thats not how it works. Not only balancing the weight, you are also reducing the weight, if the car has 300hp and weighs 2800 lbs, every 10lbs removed is like freeing up one free pony. Do that 10 times and hey, my oney is gonna be on the weight reduced car. Just ask lotus about that. Sounds like this guy is trying to say with the right suspension and enough driver skill he could wrap a caddy around the track as fast as I could with my 240. Dream on.

while on the topic of weight dist., I offered some personal experience with s13s; ka24de(old), ca18det(current) and vg30dett(friends'), but obviously u just don't wanna hear it, or any other useful info posted in this thread... as long as its in disagreement with you. grow up

Ahh both of you have been heard and weighed and now this thread needs to come to "Close". We have better things to worry about than weight distribution like who in this country has a 9 second or less S13/S14 and who has the fastest CA18DET in this country. We all repsect each other's opinion around here, so let's try and keep it clean. Not directed at anyone, either because I like all of you and you views as well as your opinions and sarcasm and bad jokes:D .

paul_s13, I meant no downside, from the weight.That motor is no fun to work on in an s13 either, just like the z32 - tight on the sides, but lotsa room up front. Whenever u pull a v6tt, it would be unwise not to tackle 'everything'. Freshen the turbos/upgrade the compressors, and the power is scary. If I owned that car I'd probably build a manifold and run a single up front to simplify things... pretty ez 2 do.

um yeah, i did see that, and honda only won by a tenth of second.that was combined scores of all the honda's vs. combined scores of all the nissan's. if you remember thats why they split up the prizes instead of giving them all to the winners.

Clearly I miss under stood you. Sounds like your still saying that weight makes no difference. If thats what your still saying then I stick with my previous statement. Don't get me wrong, you can see my point, right? Were not talking about splitting hairs, were talking about drastically changing the dist of a car, and reaching optimal settings of a race car. I guess if you wan't to brush that off and say it holds no bearing. You are entitled. It makes no difference to me what you do with your car, but it seems what you are saying is false and speculative( if thats a word ). About the type r having different dist, ff cars have completely different dynamics of attaining traction. Look at all the super cars, identical dist, 40/60 f/r with all the weight on the driving wheels. Considering that our cars are rear wheal drive wouldn't it make sense to optimize the full potential of the system our cars were equipped with? Call me crazy but wouldn't that be the ideal reasoning behind driving a SPORTS CAR, or upgrading a sports car. Makes no sense to me to just call it splitting hairs when it is a tested and prooven formula for kickin *** in the twisties. Any how sorry bout callin you a dumb *** thing, but what ever you called me a ****er. I was sad, but now I am ok.

and u too missed the point sir.Both cars, FF layout. Nissans had way more power, but they didn't 'dominate'. They still struggled.

...push your datsun then. I ain't pushin' nutt'n... don't care who made it. I'd rather drive.

"the fastest CA18DET in this country" ??I wonder

14.5driftthere's nothin' constructive I can add to this thread. My 'firsthand' experiences with the 3 s13 swaps is just that... fine if u wanna call it mis-information... just curious as to what you're basing that on. Feelings?anyhow, disregard my input.... carry on with the 'formulas'its all good

I'll have a Black 92 SE coupe on the market soon. It will sport a custom manifold, T3/T04e turbo, HKS wastegate and a bunch of refreshed goodies such as headgaskets, rod bearings and rod bolts.

Come on man, I don't do loggy-style:D ! It's going to be equal length header-style and it's going to be more of a semi-marketing ploy to assist guys with CAs who don't have the access to custom manifolds. I'll do it nice and then get rid of the car because I have too many.
