Setup will be done in 3 weeks now I have to take my 410s out from the blower setup but not to sure which to choose...now my 3.27s on the stock limiter in 3rd would max out at abou 121 122 but at the same time didnt give me time to shift into 4th when I had that on my vortech so being the sc was rpm driven would I have this problem with the turbo too with a 3.27...I dont want a gear that stretches into redline so much I cant shift in time to 4th because its so damn long...would be nice to trap higher then 122 I was thinking a 3.55 just to get into 4th quicker if that 3.27 is just going to stretch out 3rd to the point I cant shift without passing the line

You have a 4v car why are you so worried about spinning to redline ? If the turbo is properly matched for the setup you should be making more then enough usable torque before then. 3.27 isn't bad and a 3.55 would help spin it up but you want the slightly lower gear to load the turbo. Especially on a stick car where you're going to need to do things like anti-lag launch control methods to leave the line in power. Do you want to be in 4th before the traps ? Why ?

Few mods nothing special.
I know about load and all I just wasnt sure if I would be stuck in 3rd to the point that if I try to shift it be pointless because I'll be passing the line like I used to so I would just have to let off but being its a turbo should make more mph through the gears anyways unlike my old vortech setup when it had 3.27s and I will be using an Anti Lag I want those 1.4 60's and I have the suspension for it and on a slick too...If it doesn't go 10s in the first 3 passes I make I won't be happy lol...its just a Mp70 with a .96 exhaust on 11psi....built tranny, upgraded clutch, SRA swap and the UPR rear suspension kit out back and plan was 3.27s so I will go back to that and leave hopefully on about 8 psi or so and smooth sailing from there.
with the 3:27s you will have longer gears. Third and fourth is where it really shows
Longer as in what the rpm / mph difference will be different then the vortech with 3.27s ? I was thinking so as well so I will make that move to a 3.27s...if I really wanted load I could go 3.08 lol
What were you running in 4th through the traps ? my car will only be making 500rwhp right now with the current motor but off the anti lag and a 1.5/1.6 60' 10s should be realistic.
I think it depends on whether you plan on forging the motor down the road. If you go 3.27s and it's putting you right at the beginning of fourth you can always run a 28" tire with those "chevy ridin high" springs

those shits were changed 1 or 2 weeks later for UP..shiit
with the turbo it should be pulling a faster MPH tehn the vortech so may be ok with the 3.27s...as long as its trapping at least 126 im cool with that...130 would be nice...we are going to make sure it launches like no 2moro...but I may break that pos T-Lok with slicks and leaving on 8-10psi from the anti lag

Its going to change the whole rpm band. I had a vortech before this and its like driving a different car. What I mean by longer gears is I dont have to shift as soon as before. It makes alot more torque in the lower rpms because turbos are load dependant. The less gear it has the more load its putting on the turbo to move the back wheels. So it will get into boost faster and stay into boost longer. The power band gets so fat, that the car is actually moving alot faster at less rpm than before. So while 4:10 cars are shifting, your car will still have almost 1000rpm left before its done making power. Huge advantage

lol i wouldn't be surprised, might have to go 33 or 35 spline

yeah I know I've had a turbo car before so have an idea about the load i just havent experienced a car go from SC'd to Turbo so didn't know exactly how much is changed I know the benefits reason of the swap...looking fwd. to actaully making trq for once...and the fact I make full boost under 4K and not worried about belt slip...500rwhp on a turbo setup should do a lot better

31 ones should be ok for now hopefully...but not the factory T-Lok...goes to show how built the rear isn't...now only if Fiero knew lol
if he was trapping @ 128mph i would guess that was top of third with 3.27's.
load helps spool a turbo yes but imo you still want to be at the end of fourth gear in the quarter mile, the logic of banging gears to get through the quarter mile still applies. i went through the traps at 134mph with 3.73's, im switching to 3.55's and hoping to raise that to about 148mph with some more boost.
another thing to consider is you want to stay in your power band as much as possible, if you go with too long a gear you could in fact drop out of your power band.
get the car set up with a good two step and everything else is down hill.

Go with the 3.27s and take it to the track. If it's not right then go up or down depending on how it acts. Tire size, trans ratio and RPM will matter too. A safe place to start would be 3.27s and try it and I think you'll be really close to where you want to be.
Yeah combo will be 3.27s on a 26" tire if not maybe 28 if I come across on a deal for tires 27 or 28"s but as long as the AntiLag that's said to be able to be worked into my tune works fine I'm thinking I will be just fine with my suspension setup to get out the whole pretty decent (1.4/1.5 60') and follow that up with a 10sec pass
Wanna swap pumpkins? I've got an 01 with stock 3.27 gears, even with shipping it'll save us a ton of $$$. I've been itching for 4.10's in with my V2-SQ.
I want those 1.4 60's and I have the suspension for it
