what is needed from a stock car to get it to 650 rwhp?what kind of mods could be done for say 15 k install included?

Go to engine packages, 96-2002 650R $15,900
Stage 3 heads, cam, roller rockers, headers, exhaust, valves, hi-flow cats, light flywheel.
Did it, love it.
I guess if I put back on my stock exhaust and asked Heffner to tune it down a bit, 650 rwhp would be possible!![]()

I'd like to take this excellent question one step further and add to the equation:
What is needed from a stock car to get it to 650 rwhp? What kind of mods could be done for say 15 k install included? While keeping the motor all NA without a blower,NOS or turbo solution?![]()
$10-12K roe charger, roller rockers, exhaust.
proven combination.

In summation its either NOS, ROE or a Stroker. Correct?

The car Dave is talking about is a stock '97 with exhaust, t&d's, 8 # Roe charger, with a 40 shot of nos and rwhp was 705 and rwtq was 917 on a soft tune. It will run 9's in Topeka or the Kevin is going to drop me as a friend. My car has a mild cam, exhaust,t&d's, and a little spray a laid down 641 & 820. You can put 650 to the wheels for under $15000 very easily.

95% correct - you could also do it without a stroker or boost or NOS. Not sure how close it'd come in with the $15k budget however as I've not priced up what it would take - but I can tell you the power would be easy to achieve if you ditch the hyd lifters.
As for loss of bottom end on a n/a engine - if you want stomp pulling power from idle - buy a diesel. Guys - this is an exotic sports car with 500 cubes. If you want stock off idle performance - keept it stock or use NOS or boost.
With that size engine you could make a lot of n/a power and still have it retain more than enough bottom end to get groceries. Real performance engines get up and go thru 6000rpm and beyond. Anything under that has a lot of untapped potential left in it. Personally any motor I had built for myself will easily pass 6000rpm and beyond because 5600rpm shift points belong in a sports truck,but I understand why some like the rpm range a stocker has.
As well as the options others have suggested I'm confident that Heffner Performance could provide a solution in that budget using a variety of solutions and selecting the one that best fit the customers requirements.
Personally - I'd always build a great foundation first, then do whatever I wanted after that - though starting with the end in mind.
If 650rwhp was my goal - I'd go for an all engine everytime.... but others would do the easy thing and bolt on a blower...
do whatever takes your fancy - one will behave like a thoroughbred horse, the other like a stock car on steroids - take your pick. The boost option will make more torque than the n/a option but the n/a option will be quicker on a road course if set up right
summary:
if you want to to behave like stock normally - boost or NOS
if you want it to behave like a hi performance engine you can still drive - build up the engine.
There are ways of being able to do both in stages - if so the best thing is to build it first then bolt on later.. most people just bolt on, and to be fair the engine is good enough to work most of the time, but you can't beat a good foundation laid first.![]()
