What next?

[renzo778]

O.K. I have a 94 impala ss. I just got the hypertech programmer in today. Along w/tha whole MSD setup, 6AL box, blaster coil, cap/rotor, wires, and adapter harness. NE sugestions on what i should do next :dontknow:? I'm thinkin about going w/a 52mm tb, or going to tha 3:23 gears. Im all ears????

Have you done any exhaust yet?? If not I would say to start there.

Cold Air intake, Exhaust, then 3.73 Dont mess with you tb, what you have is sufficient for your stock cam & heads. It'll act like a totally different beaSSt

The idea of a motor to perform better is to get as much air in as fast as you can and out as fast as you can w/out the motor leaning out. Think of it as a giant vacume...cause it pretty much is. Do the basic boltons first, CAI, exhaust. Etc. Then the next purpose is to get the motor to spin up faster, whether it be a stall converter or lightweight flywheel (not a b-body thing i know) and gears. Then you work on the internals and thats where it gets pricey. But as for a bigger TB, you really don't need one until you run out of bolt ons and start doing heads/cam work. Then a 52mm will be more than enough.

BTW Its an Impala so you have 3.08's Options for 3.42, 3.73. 4.10 & 4.56
IMO Best bet 3.73

I would say sell that hypertech you just got and buy a real tune.

First thing I would do? Return that Hypertech programer. PCMforless can do a MUCH better job.

also, the 6AL box does nothing for you, until you want to spray nitrous.

Don't waste your time on 3.23's. I went from 3.08's in my 96 9c1, to 4.10's, and I love it. It gets off the line ALOT quicker.

If you add a 52mm TB(one of the last bolt on mods, as far as $$ per hp), you need to have the PCM tuned for it, otherwise you run the risk of burning the trans up from not enough pressure.

I would suggest you do a Catback. Get a pypes X pipe 2.5", your muffler of choice 2.5"(offset in, offset out), and 2 dynomax/walker over the axle pipes 2.5", then what ever tips you want, and the hardwear to clamp it.

OR, theres the "215 catback, which consists of 4 pipes, and muffler of choice. The 2 cat to mufler pipes are 45687 & 45688, then the over the axle pipes are... 54016 & 54017. This gives you a full MANDREL bent 2.5" catback, for about $215 using Summit Turbo Mufflers. Which actually outflow flowmasters, and sound pretty good. Or theres the JEgs catback for $255.

OR, the ultimate in cheap-o, Add some stright pipes where the mufflers were, and leave it at that. i currently have that on one of my cars, and I get compliments everywhere I go, and It cost me $40. A full 2.5" catback WILL give you more power, since the stock pipes are 2.25"*crush bent* to the mufflers, and 2" after the mufflers*also crushed very bad!!*

Right now I have that exhaust hooked to a set of CIA Tri-Y headers, and cat delete pipes. Sounds freakin NASSTY, check it out.

IMO Best bet 3.73

with 26" tires 3.73's would be my choice too, but with 28" tires, it;s 4.10's in my book, since the 4.10 28" combo is only slightly lower than the 3.73's 26" tire. I love the 4.10's in my 96 caprice.

Here should be your mod list

1. tune it up, plugs(autolite 104), wires(MSD, Magnacore etc), fuel filter, clean the TB/MAF, oil change, EGR valve(for the 6 speed F-body, trust me), PCV valve(AcDelco!!), and O2 sensors(AcDelco!!!)
2. Tune up the other things you forgot, and run autoRX thru the oil. You WILL see a 5-15PSI jump in compression.
3. TB-bypass, & 160* Tstat, air pump disable(yes, even CA people can do this! GM said so!!)
4. Cold Air Intake. Many options. RAISS, SSRI, Ram it, K$N FIRK, PVC to cut up stock box(works better than you think! Works better than a cone filter without a heat shield)
5 Exhaust, Full catback. Many options. Do a 2.5", Mandrel bent if you can. The stock cats flow very well.

Past here, you can mix things around until # 14

6. PCMforLess, I opted to wait until I had my headers and 1.6 rockers, and 4.10's so I only had to payfor it once.
7. Headers, Don't waste your money on shorties. Flowtech 49100's work very well! Clear Image Auto Budgets, or Tri-y's.
8. Valve springs(stock ones SUCK!! Actually my 1st mod, after intake and exhuast) and 1.6 roller rockers. Valve spring Comp 26915, with 787 retainers, 1318-16 Comp rockers.
9. Racetronix Fuel pump harness kit, and Walbro 225 pump. You don't NEED this, but it ensures you don't go lean and detonate, and kill your engine. Also makes it so you don't need bigger injectors, as soon. Since it boosts the voltage at the pump, and the pump can support more power.
10. 4.10's/3.73's, Eaton posi(the stock posi is WEAK... hit or miss) and a full diff rebuild.
11. after the higher ratio gears, you might need a Denny's driveshaft, do to vibes.
12. Trans-go Shift kit, Get it from ProBuilt Transmissions. Cheapest, and best put together I have found. Helps the trans live longer. A MUST.
13. High stall torque converter. a 9.5" unit. Higher stalls, in a 12" is not good. They are sloppy. I would suggest Edge, Yank, or Precison Industries(PI/Vigilate). These brands in 9.5" drive very much like stock when cruising, and lock-up saves you from losing MPG on the highway.
14. F-body MAF, 52mm TB(have your stock one rebored by the guys on ebay... Better quality than the aftermarket units. add an air foil at that time) SVO 30lbs injectors. stock ones are normally ok, even with a beigger cam, but if your gonna go any further, you might want to get these. NOTE: These 3 need to be delt with by PCMforless!!
15. Electric water pump. The stock pump does a great job, and doesn't suck THAT much juice. These have been known to fail(don't know how often), and when they do, your SOL unless you have a spare, and are watching your temp gauge

16 bigger cam. I'm going to get a custom one from Advanced induction.
17 Ported stock F-ody heads. The aftermarkets(as cast, and about the same cost), can't compeat with Advanced Induction ported stock Aluminum heads.

This also doesn't mention taking care of your brakes, suspension, or dying trans. Thats a whole nother thread.

What else ya wanna know? :P
