Hey guys, I have been thinking about building my motor up with some better internals and was wondering what people have used for all the parts.
Also what would the total cost be?
And what would I expect it to handle hp wise?
Is it worth it?
Is it worth boreing(sp) it out?
This would go into a 09 tc with fi done if I decide to go through with the build...

going forced induction or all motor?

xsupermario

forced induction as stated above.

chintastictc

do some research yourself and learn before you start building..forced induction is not a good idea if u have no clue what your doing...unless you buy an already turbocharged car lol

fi is not an issue I know a pretty good amount about it. Was just wondering what it would cost to do an engine build. Also how much hp could the stock 5sp handle?

xsupermario

I just read that a lot of the stock parts should be fine up to around 400-420whp with a good tune, so Im thinking I will just buy the rods for now and if anything else goes il just buy that since I only want around 400whp anyways..

My other question is how much does the stock 5speed handle?

where did you read that? The stock internals start to go around 350hp most commonly..of course a lot of factors play in that but thats usually the place where people start to worry about build.

yes, they're talking about a time attack car. no daily driving there, so reliability isn't their biggest issue. keep in mind your stock clutch will also start slipping after around 300.

still, its not like im gonna be running it at 400hp all the time. So I don't think that will really matter.
Also I was already thinking of upgrading my clutch and flywheel when I do this.

Chris Rado's tc is slightly modified with pistons and rods, and he can get it up to 500hp...

Now thats what I like to hear!

lol even in that thread they only prove my point. I'm sure the car can last a short period of time with 400whp but in terms of reliability its not going to happen

wow crazy time attack tc

Thanks for that, decided on pistons, rods, and probably valves and springs.

I have 2 built motors now for my tC. One is strictly race and the other is for everyday driving. both my motor use the same turbo setup a GT-35R. One motor cost $8K FULLY BUILT and sleeved, one block was $2K fully built, but not sleeved.

All depends on what specs you are going with. Small turbo, small modifications, Big Turbo, big mods.

Street wise if your looking for anything over 300WHP, Pistons, Rods, Vavletrain, Clutch are an absolute MUST for reliablity.

All depends on what your looking for HP/TQ wise.

Well I was hoping for around 400whp, but i think i might just buy a turbo kit for now and run it around 10-12psi. And then buy myself a 240 or something for the weekends and races. because with that much power there will be a lot of wheel spin on a fwd car.

I would not suggest running anything over 10PSI on a stock motor, not to mention your gonna need a clutch for anything over 8PSI.

clutch and PSI dont really have anything to do with each other.
you could be at 35psi and still use a stock clutch if you have a crappy tune...
catch my drift?
