Engine Building Questions
Ok, I realize that my last couple threads have been All questions and have went no where. But i have recently decided to turbo my car after all and i have a few questions about pistons.
My Original plan was to just throw a turbo set up on the car but the more i thought of it And how many people get tired of just 10lbs I figured i would start with my engine.
My engine is the 2001 vvt 1.8 with 84,xxx miles on it. It does not need a rebuild However i Am going to pull it apart and Build it.
My plans are M Tuned rods, Billet oil pump. re balance crank and all new bearings stock head maybe some port matching small things but i do not want to port to heavily At this point.
I have built Motors before just Not a Bp.So i have a few questions for you guys. I know there is a lot of questions asked on this forum But i Have searched and only found vague Answers So my last option is to ask directly.
First question is With the pistons. I Know that i am 10.0:1 compression on this motor And with a turbo you would want to be lower than this. So my options are???
Aftermarket pistons, Wiesco or something.
Stock pistons from a 99??? will they hold up to 300Whp
Or should i just keep my stock pistons and coat them. And deal with the higher comp ratio
I will not have the turbo set up complete when the motor is done being built i will break the motor in and drive the car without boost for a few months. so i do not want to drop the compression down to 8.0:1 ,Also are the aftermarket pistons loud. And i Also Have heard that savington is running a set with a large clearance and the motor doesnt last as long. This is planned to be a DD car with some ***. Not a race car. So i Doubt i will bore it maybe just hone it. So What are my options for pistons.
Second, What about Over sized valves? in some threads i have seen people mention that they problems with the vvt setup as far as lift and interference.
I would like to keep the motor a non interference set up. It gives Me a sense of security When I beat on it.
I have moved so i no longer have my shop. So i will have the lower end Built be a local engine builder that has a good Rep. So i need to have all the parts and the game plan together before i drop it off.
If this has been answered 20 times like the churbo threads i Apologize in advance i did search and couldnt fine anything conclusive. I have my Flame suite on. But i appriciate any help reguarding the subject.
P.S. My Grammar Is Terrible I Am posting from My iphone Without Taptalk. So Spare me Please.
