I've started researching my engine build for my 87 GN. I've had the car since I was 18, and quickly blew it up like a stupid kid trying to impress a girl.....lesson learned. I removed the motor and found a spun rod bearing. After taking the block and crank to a machine shop I was told the crank was toast. So at the very least I'm looking at putting a new crank in.
The main purpose of the car will be a street car with 1-2 trips to the track a year. I have tons of friends with all the typical import turbo car including Supras and some very build VW/Audi turbo cars. Basically I'd like to be able to hold my own against them in my "old grandma Buick" as they all say! My goal would be 500-600 chp. The suspension would be set up for more a pro touring/good handling setup....so I figure my 1/4 time would severly suffer. But I'd figure with those power levels and sticky tires I could at least be in the low 11's, and well in the 10's with a proper combo for drag racing.
So basically I need a crank at the very least, so I figure a stroker kit isn't going to be much more than a stock crank other than machine work. Here are some questions that I have come put with so far.....
Am I doing this completly backwards? Should I pick a turbo and build the engine to it or should I "overbuild" my motor now and choose the turbo that works the best for my budget/driving style/power expectations/engine build?
Any downsides to a stroker crank? I figure the cost is going to be around $500 more more parts/machine work? (vs buying stock stroke crank/rods/pistons)
Billet center caps would be a must with my power figures, but at what point would I was to use Billet front and rear caps? The rear is pricey!
Considering the $300 difference between ported stock and new aluminum heads why would I want the iron heads? It there somewhere that I have yet to find that will port your existing iron head for a lot less? I figure $300 is well worth the benefit of aluminum head.....unless there are other hidden costs involved.
If going with a stroker kit what cam should I be looking at? I was looking at the XR3 & XR4 cams.
I think that about covers the major components. Is there anything I've missed that I would be an idiot not to address?
