i got a ls/vtec in my 90 civic hatch. it currently has ctr pistons and the head has been shaved .020 running a cr around 13.1. need some sugestions on a rod/piston combo for 8-10 pis turbo setup.

o i will most likely be able to put 101 octane in it all the time.

x2

an dont expect much with 101 octance and 13:1 compression you dont have diesel

will factory ls pistons work for 8-10 psi?

Sure they will work but its not advisable. Hell the CTR pistons you have will work just throw a 5 layer head gasket on to bump up the compression! LOL What was your question? What stock pistons and rods will work? Eagle Rods and CP/Wiseco Pistons 9.0:1 but given your head is milled it will be slightly higher in CR and that also depends on other things as well.

I'm pretty sure you'll get away with just using the Ls pistons. But the stock rods and pistons can only go so far. If you want more reliability and power, then just get some forged rods and pistons and a very good tune.

i dont wanna really go too far in terms of horsepower. a quick spool for like 8-10 psi. maybe even 5-7 psi. i got some people to do some serious tuning for me. i can get some ls pistons no problem. tht and im working on a limitied budget. forged rods and pistons are kinda outta the question right now. ive seen people on HT running stock blocks with more psi. i just dont want to break it, it is my dd.

Then you shouldn't turbo it. Not bein a dick, but even with built setups there is a chance of blowin the engine. If you don't have the cash to do it correctly right now then save up and do it right when you can. A 13:1 cr lsv is likely pretty peppy. Hopefully that can keep you happy until you save up the funds.........

With 13:1 cr you are really askin a tuner to do some magic to make decent power and have you engine not detonate. You can use a thick hg like stated earlier but your best route would be forged rods/pistons and lower cr. Even the stock ls pistons would give you more room, and could get you into the mid-high 200's fairly reliably. Just depends on what you can live with. Most will say not to attempt the 13:1 cr with boost, especially if its your dd. GL.

well now im on a budget b/c i spent most of the money of putting together the turbo components. onlty thing i had left to get was the turbo itself and a chipped p28. but now i gotta get some pistons for it to lowert compression.

 

i found some low CR pistons on craigslist. Nippon 8.5 to 1. would they work? comes with pistons and rings and wrist pins

o they are brand new never been opend for about $120

 

bump

 

just try selling your head or trading it, and buying rods/pistons that are better suited for FI

found some pistons, low compression. should i run with 8.5 or 9? i do no i gotta bore out the cylinders, looks like scuff marks or somethign inside the walls

 

back up for the eagle rods and cp/wiseco pistons. 9:1 compression go make some boost

 

eagle rods and wiseco's here

 

appriciate the info fellas, but i have scrapped tht project in favor of a 96 si coupe and a b20 or possibly cr-vtec. look around for the build thread. should be posted by the end of the month.
