Nitrous on factory rods and 10:1 pistons

allen2000rt · Post by **allen2000rt** » Wed Mar 25, 2009 8:50 am

Hey i am building a single cam engine for my 2000. i was wondering if anyone knows if the higher compression pistons are to much for a 100 shot and also will the factory rods hold this with out issue. As well hill a head spacer allow me to use srt 4 piston and rod setup as a long road engine?

srt pistons and rods will never work in a 2.0 Where are you getting 10:1 pistons that fit factory rods. I would not spray more than a 75 shot WET on a stock rod engine.

im w/ hybrid on this one, I've been sprayin a 75 shot on my motor for about 2 years now but I would get new rods before stepping it up anymore if i were you

Str8 guys thanks for the info i also have a twin cam head for the head swap in this car i just have alot of options and am trying to get them weeded through for the easiest way to go. im thinking hypereutetic pistons thats reason for the questions bout nitrous. ne one here want to buy a log turbo mani for the twin cam let me know ill sell it for 50. ne way i was thinking using and srt4 turbo mani if i do the head swap is it worth it or better to build the single up na? can i use the srt4 intake mani as well im pretty sure the heads are the same on the dohc and srt only diff i think is the block height in the engines and internals right?

dual cam is better for all motor or boost. Have fun tuning it unless you have a standalone. The heads are very similar between dual cam and srt. the srt intake wont fit on a regular dual cam head unless it is a newer pt style. You can always re drill the intake bolt holes... The turbo will fit. Hypperutectic pistons are a good comprimise between stock and forged. I personally have forged stuff.

thanks hybrid 01 i think ill just build na and use nitrous i like the turbo idea but dont want to spend so much time tuning and a wet kit with mild tuning on all motor should put me in the 250 to 300 range with nitrous depending on how top gun or hensley racing does my head. and the crane or comp cam i plan for using.

a maxed out single cam build should make around 170 hp

not if Sgt Brad has anything to do with it.

maxed out SOHC should be in the 200-220 area.

I'm talking for the average guy to build. 10.5:1 comp ported head and crane 14 etc.

Yea im taking the time and money because im aiming for 200 then add a 75 shot should put me where i want because i want to play with it and get into some autocross around here. if you have ne suggestions for na build im willing to listen i know alot about the neon and there engines but this will be my first build even being a neon nerd im always willing to learn.

please read up on the info here before leaping into a project.
The stock rods have been proven safe to about 250ft/lbs TQ before snapping.If your getting as involved as your talking.....
Forged rods - $600
Forged pistons - $500
Balancing of the engine after the above - $?
DOHC conversion - $1000
Forced induction - $2000
Standalone pcm - $400-^^^
The above should get you to around 200hp-300hp range on a 2.0
------------------------------
The above is a quick estimate
------------------------------

I hope you accidentally added another 0 next to the Forced induction section cause thats a ridiculous amount for a nitrous kit

For boost, not spray, that's a safe enough number. I spent $600 on my nitrous kit from zex brand new.

Modernperformance.com has a good JE Piston/Eagle Rod combo for $800.

200 WHP on an N/A 2.0 sohc motor is a pipe dream. Only if you have lots of cash will it be possible. To be competitive in autocross you really want to build for a certain class, you're going to be put into a class where the car isn't competitive if you do all the motor mods you want. I'd expect with a decently ported magnum head, and 10.5:1 pitsons and rods, with bolt ons, and a cam (comp 400 is the only one available at the moment) you'd be stuck somewhere around 170, and that's with a standalone computer.

Well we shall see there is a dyno just up the road it will probably take me a few months to get it together but the engine is bare block and ill order pistons and rods this month. I will have it dynoed when done. May 170 is it but worth a shot i think i can hit 200hp out of it. all motor its a good challenge we shall see though.
