Turbo Gasket

[O_GT]

what do you guys thing of this link (http://www.kspec.com/list.php?ac_id=85&ai_id=1007) Ive been thinking of geting this for my custom turbo kit

Seems like that would be a good thing, although I think the better choice would be to save up an extra 200 and get low compression pistons, then, from then on you don't have to worry about boosting too high and frying your pistons.

Pistons is the way to go but it's more than just an extra $200 because I'm guessing that you'd have someone else install them and that will be expensive.

Well I can install them myself but I'm too lazy.The way I see it for my goals that should be good.Plus it will only take me like 4 hours for the head gasket unlike more than a week to do the pistons

The Alpine Turbo kit comes with something similar. It works great and I've noticed no drivability problems..

I have a quick question... So lowering the compression ratio makes it so u get less power per psi right? So some example figures would be for example lets say u have 10:1 compression with 7 psi, and then lets say u lower the compression down to 8:1, but now you can turn the psi up because its safer and the pistons aren't compression as much, to lets just say 10 psi. So these 2 values will put out the same horsepower, so I don't really get the point of it?

You get a bigger margin of safety with the lower compression

What happens with higher compression is detonation. Detonation is caused by the fuel being ignited too soon. Since the timing cannot be adjusted easily on our cars, advancing it, which reduces detonation at high compression levels is not possible. A member on HP built a 2.4 Sonata engine for his Elantra (95) and used an Eclipse head, which has 16 valves (instead of 12 for the stock Sonata head). He wound up having a 12.5:1 compression ratio, which detonated like crazy even with high test gas and advancing the timing as far as he could get it. Of course the power from the engine was killer, but he could have busted a rod easily.

When you force feed the engine, it will increase the chances of detonation. Lowering the compression reduces the chance of it happening and enables the car to run on regular gas

thats what I was trying to say by saying it would give a bigger safety margin.I guess I should have been more specific

These days, if it isn't spelled out for them, some people can't seem to figure it out. I know from experience that you must have a safety margin in order to make it work.

On the Alpine supercharger for the V6 Tiburon, Alpine Developments specifies you don't need to put in forged low compression pistons. However, I know 2 people with it and they have had problems with drivability with the supercharged engine at a stock level. For one, when you kick it in the ***, you do get some detonation and the cel does light up (due to the maf sensor being too small). You must run premium gas in it because it can detonate so bad it knocks on you.

My opinion is if you are going to boost the engine, you better add forged internals to get it to last.
