Hi

I want to put 19's on my 1996 i30, I believe 19's give that perfect look on the i30. The only problem is I am worried that it will hurt the proformance of the car. I will probally be buying an intake, y-pipe, hi flow cat, b-pipe, and JWT chip. With all of that done I was hoping to break into 14's in the 1/4, will this happen with 19's? Can anyone recommend a good set of 19's?

 

I seriously doubt that you'll get into the 14s with 19s and NA (maybe if you are 5 speed with all the bolt ons?). 19s will definately hurt the performance of your car. I have 19" Mille Miglia Evos on my I30 and I love the look. You can find these at tirerack.com.

 

you think with those mods I listed I can hit 14's, My cars is an auto

 

I think with those mods that you'd have a good chance at 14s if you were running stock 15s. You can maybe add a VI or headers to speed you up a little bit. Honestly there aren't many people on here that run 19s at the track, but they will definately slow your times down. I'd think you'd run low 15s with all those mods and 19s and you should crack the 14s with stock wheels. That is just going off what I've read in the 1/4 mile forum. Check it out there are a lot of different 4th gen timeslips on there with various mods.

 

Well I am not really tracking the car, this is a really a street car. I just want to be able to outrun most street cars.

 

i heard you had modify the transmission if you get bigger rims...is this true?and whats the highest you can go before you start degrading performance? anyone have the nismo rims?

 

I know of some light weight 19's. The HRE 446R are Three Piece Forged too bad Wheels Boutique sells them for $4,800 w/tires.

 

well...u can see why most ppl have to dream about HRE's....

 

Modify the transmission...where did you get that from

Good luck getting your auto into the 14's with just bolt-on's and 19's. Unless your gonna lay down some major cash for forged 19's they are gonna weigh at least 25lb...actually, more like 30lbs each. I bet with y-pipe, intake, catback, ECU, and 19's you would run a 15.5 at 90mph or higher. Not fast at all.

You say you want a fast street car? Well slaping on some 19's and having an auto is not gonna make that happen. And you want to "outrun" most street cars huh? So, like minivans and SUV's? Or are you talking about moded cars that are daily driven? I run low 14.1-14.2's with bolt on's and I am far from a fast street car.

If you want 19's then go for it....but expect a y-pipe, intake, and ECU to just get you back to a little bit faster than stock while running those rims

 

im actually get 18's....i was just asking some questions...

 

what would happen if i got 18's...they're pretty lightweight i heard...
RH c2000s....

 

All I was responding you about was your transmission statement

 

yeah...i heard somewhere that some shops actually have to do that...
like...gear ratios or something...i cant remember it was like two years ago...

 

but yeah...u know how much the RH evolution c2000's are gonna weigh?i heard they're pretty lightweight....but not really sure...im getting them off of an actual streetracer so...i dont really know what to think..

 

"An actual streetracer"

 

Centerline makes VERY light 19"s and other higher priced wheels are also light weight

my Blitz Technospeed 19"s are 25.2 lbs and they are forged 3 piece... I do notice that my car is slightly slower... even if you get the lightest 19"s the added rotational mass will make you slower

 

thats what it thought...

 

well...this guy's only lost like 3 or four times...only to a viper or something else...

 

just trying to hit 300 posts..

 

So then 18's is the way to go if speed is an issue?


Also if you break into 14's that is fast for a street car, most cars like: rsx typeS, civics, integras, gti's, jetta's, es300s, bmw 325, 318, 328, accords, TL's (non type S), tsx's, preludes, a4's,mazda's, mercedes c320,e320, etc etc etc, it is cars that you will see on the road. Most of the cars that I listed run 15's, 14.8, 14.9 etc.so if you run like 14.7 then you beating this cars and that is all I really want. For all the other cars I have my other car!

 

hahahhahahah....

okay seriosuly though i was thinking rims.. and i want to know to get 18 or 17... imean performance wise.. for a little street fun... whats good.. 17?... i was gonna have the 5 series rims.. the ones that look liekt he mesh .. ahh with the little lines.. u know with a silver lip.. anyway rims like that.. customed.. for mine.. yes i know "mesh looking rim" sounds stupid. but i just dont kwno how to describe...

Was that towards me of was that in general? Also for a 5 series or maxima?

 

Also I have another question:

I was readig the older motor trend mag. and they stated in the 1997 infinti i30t with 190 hp ran 0-60 in 7.0 sec and the 1/4 in 15.5 in a newer issue they ran a 2000 infinti i30t with 227hp and it ran a 7.9 in 0-60 and 16.0 in the 1/4 both cars were auto. Why is this?

Do the newer i30's have more weight than the older i30's? The new i30's have 37 more horses why are they not faster?

 

An additional 250lbs in weight doesn't help that 37hp. Also, the that additional 37hp is only realized above 5500rpms which means the VQ can't take total advantage of the that power in the 1/4 mile. The 2000-2001 I30s are much more sluggish off the line because of their weight and that kills thier 1/4 mile.

 

LMMFAO!!!! Uh-ohhhh

 

I could see the 250 lbs slowing the car down, but the newer i30 could still pull because it does hit the higher rpm's, It is just like the vtec etc.

 

Do not ever say "it's just like vtec" It's nothing like vtec in shape or form.

 

You mean like the rims in my sig, but only larger diameter

 

well it is like a type of vtec ( is that better ) once you hit a certain rpm you get a certain result, honda uses the differant cam profile to control higher lift on it's valves, nissan uses it different intake runners to allow air to flow faster into the cyl.

 

Nissan has variable valve timing as well.

 

on the newer models or the older models?

 

Also what about 18's on the i30 will that hurt the performance of the car?

 

Any heavier or larger diameter wheel/tire combo than you have now will hurt acceleration. How much heavier depends on how much it will hurt. For every 1lb of additional rotational mass is like adding 8lbs to the weight of the car. And roughly for every 100lbs added to your car it will be .1 slower in the 1/4 mile. It's probably more like 85lbs for the maxima...the lighter the car the more weight effects acceleration. For example, if your I30 had the 14lb BBS mesh type rims that come on the T model and you replaced them with 25lb 18's then you effectively increased the weight of the car by 343lbs. But don't forget tire weight. A 15" tire in the same diameter will weigh less than a 18" tire of that same diameter. A standard 15" tire is around 25lbs and an 18" tire is around 30lbs. So there is another 120lbs to add in. In this example you would be about a 1/2 sec slower.

I have tested this at the track with different rims and tire weights and it holds true.

So if you are seriously into performance then there is no way you will want to run heavy, large diameter rims. Sure they look cool but all they will do is cancel out any performance mods you have done. That is why I run a nice set of 15x7.5 15lb rims. I use to have some heavy 17's but then realized what a waste it was to spend money on performance mods and lug around these boat anchors.

There are plenty of fairly light weight 17's that don't cost too much. But when you get into 18's and 19's, light rims get real expensive.

 

Nissan developed a form of variable valve timing before Honda did. Honda just marketed it better. Nissan really did not think it was that big of a deal, which it's really not. It's nice to have but ignorant ricer street racers think it's like some form of nitrous or something. It did not come on the maxima or I30 if that is what your asking. I know a few years of the 300zx had it and the 3.5VQ's have it.

 

I see what you are saying with the whole wheel thing. I guess you can't have your cake and eat it too. I would just like to break into 14's like 14.7-14.9 with the car on like 18's or 19's.

I know what vtec is I know it is not nitrous, I know what it is and what it does. I really don't know much about these cars I just got the car so I really am still learning all things that the car has and comes with, which so far is very good. Like I said this is my daily driver so I am not looking to go to nuts with it. I would like to prob do an intake, full exhaust, and chip.


Also what type of gas does the car require what octane? I know higher is better but what is the min.?

 

the laugh with a quote was for you.. heh.. and the rims are for a max.. well.. i mean i30.. but still regardless.. their sorta deep... and the silver lip is classy.. then put the infiniti center cap.. give it a bit of OEM look ..

 

RACING HARTS C2s or C4s, OMG if there was a smiley on here that had the monkey jerking off, i would use it. Those wheels are light weight and look very sport. If you can find the three piece wheel with the buttons, EXTRA wack off monkey! Centerline, Racing Harts, Volks, SSR, HREs, Giovanna GFGs all make nice light weight sporty with nice lip wheels for our cars. After I finish the performance mods and body kit install for my I35, I am going to work on wheels and suspension. I, myself want the Racing Hart C2 or C4 three piece in 18s not 19s though, and with my kit and suspension OMG, Beautiful!

Anyway, back to topic. Any larger diameter wheel other than stock ie. 18s or 19s will hurt performance. There is a theory here about Mass/and rotation. More mass to rotate, more time added to the clock. You probably won't feel it depending on if you get heavy chrome or a heavy wheel, but if you track your car you will see a time difference of a tic or two. So your track time might be 15.7 stock wheels. Add 19s and you might get 15.9 - 16.0s (TRUST ME I have seen it at the track with people racing with heavy chrome on there car). Most people who drag want smaller wheels. And again, if it's for show get what you want!

 

light weight 17s are somewhat affordable. Go with those and you CAN have your cake and eat it too.

Because each rim is 2'' larger, and the rubber is about 2 lbs. more than 15'' rubber, you would think that one would be running about .1 sec. slower 1/4 times, but in my case this was not so. Because the rims I got were about 5 lbs lighter than the heavy a$$ factory chrome 15s, the larger diameter and extra rubber weight were canceled out, and my 1/4 mile time held the same.

Technically, if you do the math my car actually became the equivalent of 32 lbs lighter, but who will feel that?

If you already have the t model BBS 15s, keep those OR get the 17" 90-96 Q45t BBS rims (rare). If you have the heavy chrome 15s, then get light weight 17s and you will not have an adverse effect on your performance.

 

wtf...too mechanical....but you guys said before...that if i put 18's on my car that means i will not be able to keep up with civics???wtf???is this true???i mean...i wanna keep up with a stang or something atleast....

 

Civics have never even been in our league! You will always be able to take those little rice grinders.

First, most ricers who get those get civics do nothing to them except add some crappy clear euro tails and a fart can. The majority are base models anyways pushing 120 bhp on the 2004. Some are the rare si which is 160 bhp, and although they are light, they are not light enough to compensate for the lack of torque that honda engines produce.

With a few mods like y pipe, cat back, intake, you will destroy most civics out there even the si. The only exception would be if they have a turbo kit on car, which most dont. I beat a kid I know with a 99 si with gsr swap, cams, headers, cat back, and intake by .5 sec. on the 1/4 at the track. And I am auto (not for long though). He told me his car was about 230 bhp, but I bet he did not even have over 170 tq and that is what counts. So you should have no worries about them, even with 18s.

The only way 18s (off a prelude, right?) would hurt your performance is if you have the 15'' t model BBS rims. If you have the non t rims, those things are so heavy you won't even feel the difference.
