As far as you intake idea goes, I'd just stay with the stock one. It flows fine for your needs really.

The NNBS intake is a improvement but it's not like a must have thing.

The Ls1/Ls6 isn't worth the swap.

And the LSXR intake a waste of money for you. $1,000 just for the intake, then you need a different throttle body and fuel rail and whatever else and you are close to 1500-2000 bucks for maybe 15-20 peak. And that would on a motor that wants to sing, like it's going to make the power above 6,000rpm to show anything.

 

yeah I agree with you. any of the directions on the intake will take a few mods as nothing appears to be bolt on and work with current system... just wish i could get 3 bolt 90mm DBW TB and just plop it on there and be good. oh well

I am on schedule to get it tuned next week. woot

Do you still have the denali cluster? If so, how much shipped to 94513?

 

no I do not

 

I just went through your build thread and man you've had some bad luck, Kinda like what I went through, But when all said and done it will be definitely worth it..

just got my driveshaft back from getting new 3R u-joints and balanced. its my stock steel driveshaft that was a bit of an eye sore (rusty colored) so the guy at the shop painted it black . looks much better. torqued the u-joint caps back on and she is rolling again. ready for a tune!
