Thread: Thoughts on a full race motor setup (Turbo Posts)

without a doubt a cheap stainless one will be better than a log. I've seen the honda boys make the switch and make over 75whp.

I want a completely divided setup. You never know when you wanna go for that GT40R...

true but again is that just because due to the fact that a log mani has such short runners compared to a tubular. And im sure this causes more heat around the exhaust valves and ports due to this. Im still debating being the pieces havent been purchased yet but do you think for the fact that im looking to make only 300whp at 10psi that its worth it to just purchase log mani.

Coheed you guys talk these big turbos which makes me laugh.

When you make 500 WHP on a FWD SR20DET, you will soon come to the conclusion how silly it is. With slicks this a a 135-140 MPH car.

Coheed for a FWD street car you dont need anything bigger than a GT35R which is good for 600 WHP.

the problem imo with the log is the way the gasses merge into the flange.

if you want a budget manifold to do the job of only 300whp, consider t3 flanging and ex gating a standard det manifold

the det manifolds are that much better than any log mani out there huh. I know people have had alot of success using a gtir mani with external gate and either a gt30 or greddy 18 g turbo. Im still kinda debating, I want something thats gonna flow well enough and not create excess heat and make the 300whp give or take on low low boost. thats what im after. So the debate continues haha

It still blows me away! You are so right MIKO! It is silly. Its even worse now because it is winter time and I still havn't put my car away. Just filled her up the other day for only $22. I can't afford NOT to drive her now.

I will not be upgrading turbos. Rather I would like to see me make the best of the GT30R. I don't like drag racing as much as circuit, and since I have Miller motorsports park out here I should take advantage of it and get her on the track.

The log manifold is great, flows well, nice packaging. Top mount turbos look awesome, and they are great for up to 450whp.

Remeber I told you that Protech makes a top mount unequal length manifold that works great same manifold on Mannys car. Trust me get this one. You will have the turbo mounted in the smae position as it is now.

see there is always this back and forth, thats what im saying is a log mani really that bad unless your going 400+ whp. Im only looking for 300 but i want it to be safe and flow well enough that i dont have to worry about it and make the power i want.

The question is Will it get me there and safely or should i look into a tubular.

Everyone told me that I wouldn't make over 400whp with a log mani but I did 10% more than that.

If I were you though, I would go tubular. because the stock sr20ve cams hate log manifolds. Not enough separation between pulses and high overlap causes some problems.
