Best mods

[93Z]

I'm new to Z28's what are some good mods I'll have about 1500 I'm buying a z28 because I can't have a 5spd and Z28 autos are just faster than mustangs.No nitrous or blower or heads I'm talking simple bolt ons.


Thanx,
Arron

exhaust,cold air intake, thermostat, gears

[Mykdiver]

Torque Converter! then Headers, Y pipe, catback, intake, filter, exhaust cutout, computer chip.
The TC would drop about 3-5 tenths off your 1/4 mile times on a stock car. I would go with a 2800-3200 stall converter, unless you are primarily going to race it.

I'll go with with Mkydiver....:D

[snakeskinner28]

He asked for simple bolt ons, not the best ones. While I agree headers and gears are great, headers could take even an experienced mechanic a day to do, and gears must be done by someone who knows what they are doing. Def go with cold air, exhaust, dont get a ypipe until you get headers, aftermarket ypipes create exhaust leaks at the manifolds. Pullies are simple and cheap enough and get you about 7hp. A torque convertor would be great, i dont know much about how hard they are to intsall since i have a M6, but that will make a big differance on an automatic car. Also i had great results when i put my throttle body on, took about 30 minutes and it gave me about 10hp, people will tell you its not worth it but i had great results and all i had done was cold air and pullies at the time. Also, descreen your mass air flow sensor, wont do much, but one of the only free mods thats worth a damn.

CAI, free mods (tb bypass, descreen maf), pcmforless chip, 3:73 gears if you get an a4, cheap set of Drag Radials (nittos), and of coarse the best bang for your buck :gotnx:

This will cost you under $1500 and get you in the 11's with minimal work done to the engine. Plus if you hide it well..cough..air box...cough. Gym bag behind the seat for the bottle. Everybody will think you run high 13's. Never hurts to have 10 cars or so to play with if money is on the line. Now go take care of this problem. :spankme:

yeah go w/ simple bolt ons first!

Let us know how it turns out.

isn't the cheap way to get power is to ad NOS. I thought I saw something yu can pick up a kit for like 4-800. Yu would proably easy 150horses by hitting a switch. The down side I read that it puts like 10-15 thousand miles on the motor everytime you shoot nos into it.. I think If I was racing somone for money thats is what I would use bec yu no it works for sure. Isn't racing quarter mile? I heard changing gears is preety cheap like couple hundred .. Change your gears to 4.10 its another cheap mod.. All depends if you are racing for fun.. All depends if you are racing for fun or money. With nos you can change the horsepower by changing the Jets. Or what I heard with Carb..

sorry, I changed my mind:(

I didn't like the idea of cutting a big hole in my airwell...... if anyone wants to do it, the instructions arehere (http://www.charm.net/~mchaney/ramair/ramair.htm)

[LT4SS]

Well as for mods go cold air package and headers with flowmaster
would be a start:cool:

TB Bypass (free)
Water Wetter ($5)
160*F thermostat ($15)
LCA brackets ($60)
CAI ($150)
Nitto 555R Drag Radials (~$160/tire, got my GP'd for ~$130)
KBDD SFC's ($180) - this should be at the top for convertibles ;)
3.42:1 gears (depending on which '93 A4 tranny you have)

after that look for headers, cat-back, and definitely a high-stall TQ converter if you can afford one. The higher the stall, the bigger the cam you run later :)

I just got a 94 M6 and am wondering how to do a TB Bypass?:confused:

[mattinator1973]

Heres a link to the (TB) Throttle bypass, it wil only cost a few bucks to do .

Haven't done it myself only because I'm lazy and don't know ths size barb to connect the 2.

What is a Water Wetter?

[Steve n Seattle]

Water Wetter is a product made by RedLine (although others have come out with similar products as well).

Basiclly it's a coolant additive that increases the capabiltiies of the coolant to absorb and transport heat. Ever seen what water does when you drop it into a hot frying pan? the bottom boils instantly and the drop "skates" around the pan for a while on a layer of steam. This air-hockey behaviour is similar to what happens in engine hot-spots (although more extream, most engine hotspots are small locaized areas).

Water Wetter is a surfactant (with anti-corrosion additives) that helps "wet" the metal to increase coolant-metal contact, which increases heat transfer.

I was a bit skeptical myself. Although the chemistry/physics is fairly simple, I wasn't sure the amount of additive was enough to make a difference. At highway crusing I averaged about a 5*F drop from ~170*F to ~165*F. This was a big deal for me. The bottle only cost like $6 or less and it actually did something. :)

Considering I was fighting an intake leak that was heat sensitive at the time, I found temporary relief with Water Wetter, a 160*F thermostat, and night-driving (or at least on the highway). :)


Here's the info RedLine published to their web page(http://www.redlineoil.com), it's pretty informative: http://www.redlineoil.com/redlineoil/wwti.htm

I know a lot of people use it in there liquid-cooled 4-wheelers. It supposedly really works. I've never used it personally, so I can't confirm anything facts about it.

[Itchy]

what is KBDD SFC's ($180) - this should be at the top for convertibles .what is it

[86RedRocket]

The nitrous bottle fits nicely where the spare tire is supposed to be. The only drawback is that you will not have the spare tire or it will not be in its place.
