I know that the 3s-ge engine has a higher compression ratio than the 3s-gte (which I guess means that the pistons' head are thiner right?), but what does it change so that we can't (or shall not) turbocharge the 3s-ge?
Is it because it would (I don't know) be too much compressed exhaust gases for the turbo to hold? BTW: what does the last number in the compression ratio mean? (Like in 10:3:1) This post has been edited by dudeofchaos: Jun 26, 2011 - 10:51 PM |

its cheaper just buying a 3sgte.
high compression cars cant boost high i think the max you'd do is what......8lbs???? This post has been edited by 808celica: Jun 26, 2011 - 11:09 PM -------------------- I don't normally drive fast, but when I do its on a curvy section of this island

In addition. to achieve this you need to keep temperatures down, especially of the intake charge. Intercooling needs to be 100% efficient or better, spark plugs have to be colder to disperse heat from the cylinder at the point of ignition. It's a good idea to use a fast road or rally cam, reducing the restriction of airflow past the valve and therefore reducing heat of the intake charge at this point and reducing the chance of creating a hot spot around the valve. Fuel and ignition settings need to be adjusted. Preferably strengthen the internals but if a relatively low boost (ie 8-10psi) is used, and and appropriate ignition and fuel map are used, this should be able to be used on a standard build engine |
