If you're dead set on a log manifold, then go for the begi. If you've seen one log mani with an external wastegate, you've basically seen them all...

yeah i understand they all look the same and what not, but i was just getting ideas for prices. and i think the begi looks goods and the welds looks great, i like the how the runners on set up with the exits, i was just hoping there was something a little cheaper for a log manifold i think begi price is a bit high.

If you want cheap then go internal wastegate. It's not like you're going to be making 300+ hp with a limited budget.

im not going for "cheap" im going for a nice "budget" setup lol. I love the sound of an external wastegate with an open dump tube.

Ok, let me put this into perspective for you, and im not being mean im being serious here.

How fast do you want to go?

Example, a new porsche 911 GT3, makes 409hp and weighs in at 1400 kg. Giving 292 hp/tonne.

To equal this in an NA thats been lightly stripped you only need to make 260 hp or so at the flywheel (260hp divided by 0.9 tonnes equals 288hp/tonne)

And the porsches power is rated at the engine. 260 hp at the engine is only about 220 at the wheels, which is easily achievable with a gt2560r (small) with internal gate on a cheap cast manifold with a megasquirt, injectors and an intercooler. And the mandatory 3" exhaust of course. This combo has been done many many times and gets you power to weight of a car that costs 100,000 euro.

Is there a reason you're set on getting a log manifold? What is your budget and what are your goals?

150, thats about the price for one on EBAY.

There must have been a typo on your invoice or the website cause there is no way those manis will be sold for 150 anytime soon. In parts only thats about right...
