5.3 Turbo with NA Cam?
5.3 Turbo with NA Cam? Hey guys,
Could use your expert opinions and insight. I'm building a 5.3 for my 69 Plymouth Valiant. Original idea was to go turbo, then scrapped it and decided to go NA. Well, things change and I am going turbo again.
I had a cam spec'd out for the car with a NA setup. Specs are:
222/226 .596 .598
This is on stock heads and will use stock truck manifolds with either a 70mm or 76mm turbo.
My question is, will this cam be detrimental to power? Should I just swap in a LS6 or LS9 cam. Or can I stick with the cam?
Any info is greatly appreciated. Simply trying to save money and forgo the hassle of having to sell parts.
Thanks,
Marvin

Just looking to make 500 streetable rwhp. What turbine would NOT be tiny Martin? I know alot of factors go into play but assuming the support is there. Nothing over the top, very simple build with mild cost parts.

This. Anything larger than a 83mm combination IMO would be fine(PT7675, BW 83mm). As John said though, optimal IMO would be a 87mm turbine 1.0 AR combo. I prefer the 1.0 over the 1.10.

1.0 means 200 extra bucks spent on the turbo....
Advance the cam like i suggested and the extra evo will work quite well when using the 1.10 T6 housing.
Bushings for the cam gear are cheaper than T4 turbine housings. Heh.

Thanks for the suggestion LilJohn,
Just to be sure, the reason for the installation on a 108 or 109 intake centerline is so that the turbo sees boost more quickly correct?
Pardon my newbie questions, learning alot by reading on here but learn just as much by asking questions.
Thanks.

There is more to it than just producing drive pressure sooner(drive pressure is what drives the turbine which makes boost pressure), but that is the general idea behind advancing the cam. More under the curve power sums it up easily enough.
Consider a water to air or air to air intercooler as well. I chose water to air as it is more compact and easier in my opinion. Check out some of the ebay ones. There are folks at over 1500 hp with a $200 intercooler. I started an account with Frozen boost and have been pretty happy with their products. The only thing I didn't like was their water tank and their ptfe lines. Lines were very rigid and the water tank was too short to be able to use a Rule 2000 pump inside.

I'm definitely looking to go with an intercooler. As I mentioned, this will be a daily driver and I want all the efficiency possible to keep driveability and dependability to a maximum.
Funny that you mention Frozen Boost, I was actually looking at their water to air intercoolers earlier. I really like the fact that they are compact and can be put anywhere without air being needed for ventilation. This Valiant has a tiny engine bay and an air to air I just dont see where it would fit with good ventilation.
Thanks for the clarification Martin. Under the curve power is definitely what I'm looking for.
