Low 15 Sec All-Motor LS?

I wanted to know what’s needed to get my car to the low 15’s/high 14’s? I have I/E/Cat right now. The plans are to get DC header, and Tokico Illuminas to match my HR Sports. I was thinking of a rebuild within the next year. How much does a port and polish cost, and what does it consist of? Also what else is needed to get the car into the 14/15 sec range? Oh, it’s going to be a daily driver.

dc header
act clutch
b16 tranny
jg or crower cams
cam gears

good driving skills that should get you mid to low 15s any if you are a good driver on a quick track high 14s are possible

Ok, I don’t want to switch trannies because I do a bit of highway driving to get to work. What about wheels and tires and suspension? what about the port and polish?

switching trannies would be a really good idea. plus, you can just have the 5th gear taken out of your LS tranny and put into your vtec one… that way you have 4 short gears an 1 long gear for the freeway.

wheels/tires. well, obviously slicks would be best. But other than that i don’t know too much. Wheels, you’re gonna want the lightest wheels possible, and small diameter. See if you can get some lightweight 14’s or maybe some light 15’s. Also a lighter flywheel will make the car feel lighter.

port and polish is a good idea. but not as important as stuff like cams.

One of the easiest ways to be faster is weight reduction. Take out some stuff you don’t need when you run at the track.

Ok I’m going to be driving this every day. I’m not going to take out my interior or take out power steering, a/c, etc… If the tranny is cheap enough, I might do that, but 5th gear swapping sounds expensive. This isn’t going to be an all-out race car. I’ve been thinking of: *=already have

Crower 402’s, maybe 403’s with valve springs
Cam Gears

*Holley Airmass Cat
*Greddy MX
DC 4-2-1

*H&R Sport Springs
Tokico Illuminas

Rota Subzero’s or Slipstreams in 15’s or 16’s.
Toyo Proxes

What other stuff would be needed?

dude, the best way is just to start building little by little… don’t worry about what “all” you need… everyone’s gonna have differing opinions.

check out B R’s (jason’s) profile. he ran low 15’s and that was before the ys1 tranny and a lot of his other mods.

that sounds like a pretty good plan. definitely go for the 403’s though. the 402’s just aren’t that powerful. Most everyone opts for the 403’s, they are very streetable (depending on how you tune them you can have no idle fluctuations or have it lope a decent amount). Some people even run 404’s on the street, eventhough for some that might be a bit of a stretch.

as for wheels, if you want speed, definitely go for the 15’s. They are not only lighter, but put the majority of the mass nearer the center of the wheel (the further out the mass the more rotation inertia there will be… which is bad in this case).

oh, and when you race you can set your illuminas on full stiff. That will help traction slightly. Some stiffer springs would help that as well.

So far, all I’m doing is replacing the stuff that breaks. Hopefully the struts will blow soon, and I don’t have a camber kit yet, hopefully I will have a reason to spend my money. I’m thinking about picking up a Skunk2 short shifter here soon, just haven’t really felt like spending too much cash.

Oh yeah, and Im looking for a 92-93 bumper conversion so if any of you in Puget sound know where I can get one (the junkyards are always out of stock) please tell me.

What about me? I ran a 14.55 with stock tranny & clutch.

oh yeah :up: you da LS man… forgot :smiley:

aren’t you gutted? can’t remember… he said he wanted full interior…

Hey Tony, were you in everett yesterday? I saw a white teg getting on 526 as i was getting off. It looked like it had a small antenna

nope… maybe roldan?

BTW, how much was that whole antenna setup you’ve got there and what kind of work is needed for it?

ok DUDE i have a low 15 high 14 ls all motor. i run this with out slicks and my number two and three piston are down to 150psi and i have underdrive crank pulley, intake full exhaust, crower stage two cams, hayame cam gears, fuel pressure regulator set it at 47psi with vaccuum hose off thats bout it oh yeah i have a short shifter and its lowered 3 inches with sprint suspension and i have sway bars ( the suspension does help go faster) and i have my rear interior stripped. so dude dont get the tranny and **** yet if u get cams and cam gears and tune them in right u will be there pretty much.

I want to get my sturts in and the wheels and tires, so I can launch at higher RPM’s. I think after that, maybe some cam gears and headers. I’m just going to start out basic, then depending on how many miles I put on it (167K right now) I might rebuild the motor in a year or so, so I probably will build the engine then. Just little stuff for now, and looks too…

ur high milg car

yes u should rebuild ur motor first and there is pretty much to use getting car gears without getting cams the point of getting ajustable cam gears is to tune in ur aftermarket cams.:wink:

I know that the power gains are like 5 hp or whatever, but at least I can say I have cam gears, they look cool, and that’s one more thing off the wish list.

that setup got me into the mid 14’s. it probably would have been better, but i never got a chance to run NA on my drag radials. i don’t know if you could get these same results though. apparently i’m a really good driver. i used to get consistient 2.1 60ft times on street tires, and 1.7’s 1.6’s on drag radials. i don’t know, i’m just blessed i guess, hehehe.

later.
