no2 on stock internals

What are your current mods?

And as far as going spray on the stock pistons....um you may not like to hear it but I would definitely swap your pistons/rods with"SOHC Neon"pistons/rods. that would lower your compression,

9.6:1 with stock DOHC pistons/DOHC head
vs
9.0:1 with SOHC pistons/DOHC head

witch would also give 420A's the ability to run higher boost levels with a budget.

I don't know about 9.0:1, but with the SOHC piston you should be around something like 9.2:1 - 9.3:1 depending on how many thousandths your head is decked from stock. I know with the SOHC neon guys it's a bit of a benefit for the DOHC pistons witch take them to 10.2:1 - 10.3:1 compression over stock (9.8:1) for N/A applications. Regardless of the compression ratio, your still limited to 300chp (depending on what shape your engine is in / fuel management used), making forged pistons/rods the best way to go for force induction. However; the SOHC pistons will allow you to have more room for error; tuning wise witch is good, especially if one is running the stock PCM.

Just my .02

For me I would not do any serious mods such as nitrous or a turbo on a stock 420a. They really can't support that much power. You would be better off to save up and build the motor from the ground up. You will gain some hp but you will not have to worry about anything breakin if you do decide to turbo or add nitrous. just my 2 cents.. I have a 95 GS and a 95 GS-T. I know to build the motor first or take car of it. My GS is at 202,000 +/- miles and NO Problems. If you take care of what you have it will always be there for you.
