thinking about doing both this week, but are there any downfalls to the 4k over the 3k, like idle, bottom end power or anything? and what dv's would best suit my my mods, i have heard a lot about the 024 but how do they compare to the 191, laser cuts, or taper cuts? and i havent been able to find any 024 listed for sale.

 

Honestly, stick with your 181 dv's they can make plenty of power. 4K's would be a big plus though, they are a lil more touchier than the 3k's but have alot better powerband.

i want to go with a bigger dv because i believe i have 131's. with the 160 pump. i keep forgetting to mention that this pickup was a v10 from the factory and i converted it with a 94 doner. ....as far as being touchier, does that mean real quick throttle responce?, or am i going to belch out an enourmous cloud every time i bump the throttle?

 

The 191 DV's are all you need. If you use laser cuts you will see a lot more smoke and no real power gains unless you use larger injector lines. Then you will have a hard time using all that fuel and it will cause smoke and higher egt's.
I have 3k gsk now and was fine for a while now I wish I would have just got the 4K. I have them just need to find the time to install. With the 4k's you will need 60# valve springs or you will float the valves.
