Throttle body coolant bypas is about the cheapest and easiest thing.

I agree just make sure you get the bigger side if the hose and get 2ft of it, dont forget the clamps. I believe 3/8ths is the size of tubing you want....maybe 5/8ths?

Do not buy the over priced kit they suggest there for the TB bypass. I went autozone and purchased a metal connection and plugs for the TB for under $8 and re-used the stock clamps. For my car no extra hose is required. The coupler came in a pack of 2 and plugs was a pack of six, split the cost in half by selling the extra parts to a buddy. I've read this mod adds 4-5 HP, so $/HP, this is the best mod you can do.

A4 = buy a stall.

**Circa307** · 08-30-2009, 08:43 PM

stall would be a great addition to it, but he said " low cost" . guess stall companies have ls1 owners by the balls because they are outrageously priced.

You got all the cheap stuff covered it seams...maybe some suspension stuff now..???

DIY port & polish the throttle body. Delete the Air Injection Reaction (AIR) system.

**Johns00Z28** · 08-31-2009, 04:38 AM

+1 for the stall....will really wake your car up but like stated it's not the cheapest mod.

I guess every person has their definition of "low cost". To me, a modification that makes a night and day difference in performance and street manners for under 1K is low cost in a LS1 vehicle.

Just about anything you do to add significant power is going to cost you. If you want to play, you have to pay...

like he said its all in your opinion. the stall itself isnt bad imo but you would need another tune right after. along with a tranny cooler(no more than $100). just research your mods first some need more than just the one part, some dont. its best to know if there are supporting mods needed. for example a new cam costs from 400-700, but you still need valve springs. and most do oil pump and timing chain aswell. that turns that $x00 cam to over a grand easy. that is without labor. the stuff that i was looking into originally would have been 1300 to my front door for a whole cam set up. that is just to let it sit in the garage more than likely.
