I have an 01 S2000 with 160,000K miles and I am trying to compile a list of what I need for the rebuild. I have never done this before so any advice is appreciated.



Current Setup:
-Comptech Supercharger w/Aftercooler
-Koyo Radiator
-Samco Hose Kit
-New Rear Main Seal
-Upgraded Clutch and Flywheel
-Alternator has been replaced
-HKS Exhaust
-Berk Test Pipe

I'm boosting a little under 6psi right now and my only other possible goal is to get as close to 400WHP as I can later on in the future.

The car is currently putting down 315WHP and I still don't have an aftermarket header, aftermarket throttle body, or aftermarket ECU

My Current List of Replacement Parts:
-Connecting Bolts
-Crank/Rod Bearings
-Rods
-Rings
-Head Gasket
-Valve spring and retainer kit
-Valve guide seals
-Timing Chain
-Water Pump
-ARP Head Studs

My first question:
What do I still need or don't need on my current parts list?

My second question:
What parts should be aftermarket and what parts should be replaced with OEM?

My final question:
What brand, websites, etc. etc. are good for the parts that are recommended to be aftermarket?



Thanks

the HKS exhaust loses power on a stock engine. Might want to... get something different.

might as well get arp rod bolts too yes?

 

The two websites I have been looking at for parts:

anyone?

 

Is there a reason you want to do so much invasive work?

I can givce you one good tip. dont even think about using head studs. Use stock head bolts.

 

Hi Billman, Why not use ARP head studs? I just used them in my turbo build thanks!

 

i wanna know also?? i'll be using them with the 3mm HG

 

I've seen many headgasket leaks due to the use of arp studs. Combustion pressure winds up in the coolant.

It was cured with stock head bolts.

 

Scott, why do you want to rebuild it in the first place? Is there something wrong with it, or you just think it is time?

If you are planning on boosting higher then you are NOW, Build a block for that goal.
If you are happy with it now, and have to replace it, buy an OEM shortblock and call it a day.

 

agreed arp head bolts on s2k blow... google it.. alota s2k owners have a ton of probs with arp bolts....
