i wana do an after market one get more power i have a non superchagered 04 ss so i have the l36 would this throttle body fit ZZPerformance - L67 High Velocity Throttle Body #MT-HVTBL67
or do i need to used this one ZZPerformance - L36 High Velocity Throttle Body #MT-HVTBL36
i also wanted to do a spacer with the throttle body and my only mod is a k&n cold air

 

If you did the HVTB, you would want the L36 one. OR, if you are handy with doing some metal work, you could do what I did with an L67 throttle body (see link below):
'04 Monte Carlo SS - L67 Throttle Body

Don't bother with a throttle body spacer, no need for it, but you may want to insulate that K&N intake some from engine heat.

 

Save your money, without any other real modifications I wouldn't bother with a TB change.

 

not sure how much power you are looking for, but my NA 3800 put down a 14.9 1/4 mile. my mods are an HV3, Headers, full exhaust and tuning. I am no where near maxing out the flow of the stock TB. I would think a Tb might be needed if you go GT1 or GT2 cam with stronger springs and push the shift points past 6000. or are going with a turbo.

TB spacers do not do anything for our cars. might as well put a sticker on there.

put what ever money you would spend on the spacer and tb toward an HV3 or headers. much better gain per $

 

Zzp recommends the hv throttle body with use of the hv3 (I think the er rockers may also be recommended).

 

my cold air has the heat shield and just looking at getting so extra power nothin crazy and i think i wana do a res delete and super 44s or do u gus think that would be way to loud ?
and

 

dont waste your money on a hvtb. i am a turbo car with ported heads, cam, etc on a stock tb. at my point i could probably upgrade mine if i wanted but there is still no real issue for me to upgrade yet. a resi delete will make it more raspy, what you need to look into getting IMO is a 2.5" dp with high flow cat (this will eliminate the horribly designed "u" bend in the exhaust which is the most restricting part.)

other than that buy a used top swap for around $300 and put it on. it will be more power than you will ever get out of a NA car.

as far as sealing the k&n better i agree with this. yes k&n comes with a heat shield but hot air easily goes over the heat shield and heat soaks the filter. look into cold air inductions for a true cold air intake that is truly sealed off from engine heat.

 

That K&N isn't a heat shield.

I was running that kit on my Monte, my IATs were CONSTANTLY above 130°F and this was on a regular 70° day. The IAT should have only been around 72-75°

It's just a really expensive hot air intake.

 

Home depot sellthe same bubble-wrap like insulation find on the wizaird (and it's cheap). It would be a good help to improve that k-n kit.

 

turbo i love ur car just sayin hahaha and top swap would be what the heads? and thx for all the help guys and yea i forgot about that dam u bend and u guys think i should leave the res then . and ill probly need to do cats soon any way my car is at 114000 miles the go bad around this time if i remember
