Your engine is an L67, not an L32, and please tell us WHAT parts you are looking for. I don't have time to sit here and compile a monster list of 100 parts you don't want or need.

The Series 1 won't make power at 6000 rpm'*. It'* quite different than a Series 2 in that regard. 1.8 rockers are the highest ratio anyone makes. Either INTENSE or ZZP for those, but SERIES 2 ROCKERS won't fit. Make SURE you're getting Series 1 YT rockers.

105# springs (Series 2 springs won't work):

Valve Springs, Single, 1.250 in. Outside Diameter, 410 lbs./in. Rate, 1.150 in. Coil Bind Height, Set of 12


Recommended Camshaft Style Roller hydraulic
Installed Height (in) 1.700 in.
Seat Pressure at Installed Height (lbs) 105 lbs.
Open Height (in) 1.200 in.
Open Pressure (lbs) 310 lbs.
Going back to this. My measurement on the spring showed an open valve spring height with 1.8 rockers as being 1.35". The spring above doesn't bind until 1.150". That'* good. Stock spring force at 1.35" will be around the 220 mark (1.3 was 245, 1.4 was 192 when I measured). Using this calculator:
http://www.engineersedge.com/calcula...spring_pop.htm

I get a rate of 320 using 1.4", and 350 at 1.3".

The springs listed above will be 287 pounds at 1.35" with 1.8 rockers as opposed to 225ish with stock springs, valve open force. Not too bad.

Using 1.72 as the install height (from my most careful measurement) I have 114#. 102# at 1.75". I think we're in the ballpark here. As an acid test, I measured spring bind on our stockers at 1.25"/377 lbs. These springs above would actually be 307.5 at 1.25".

So the rate is higher as the valve sits closed, and is slightly higher as well at valve open, but is slightly lower at coil bind. That'* what we want if these numbers are good.

Check me on this. I need to order them!
That'* about 2% of the total conversation, work, and calculations used to determine them. Those are the springs I used, and SHOULD be the springs you need. I'd prefer to have you remove an OEM spring and measure it. Also measure your install height just to be sure after you remove a rocker arm.
What size pulley are you running right now?

There are no larger throttle bodies that are compatible, and frankly, you don't need it Plenty can be done with the car on the stock TB.

Also, can you please read this information:

It will help us to help you if you pay attention to the details.
