Okay with winter coming up and I have a winter beater am gonna put my bonneville away for the winter since it doesn't have rust on the body (expect one spot). I'd figure this winter Ill mod my car a little but. I don't want anything major, just make it a little faster and still have the reliability of the car for a DD during the nice months.

The amount I think that is good enough to give me some more HP is about $1500.

What I was thinking on doing is...

TR55s- I know there not power adders but I have boush is my car now.
Belden Premiums from NAPA
and a new 02 sensor.
new UIM. brands?

Now with the power adders.
1.9 roller rockers
(going to need rocker bolts right?)
LS5 Medium Valve springs
INTENSE pcm
a/c delete kit (mine doesnt work and never had a/c in a car since i drove so i dont need it.)
I know theres other things. and if you gear heads have a better way at going with this let me know. am a NOOB . When it comes to this stuff so its going to be a learning experience for me. So nothing to complicated please Thanks Nick

hi the most important thing to do is the lower gasket for the aluminium one and check youre upper around the egr and while youre there a good throttle body cleaning

as for mod a 180 stat is good and a cold air intake whit the tr55 is a good start

for rocker the ER rocker from zzp are the best for a L36 whit new bolts
and for springs the stock one should do if ok because the Ls6 springs are hard on the valve train
