I'm planning on purchasing a Del Sol w/ a B16 so naturally I began thinking of various ways to modify it. Upon browsing around the internet for information I ran into a few questions I couldn't find a direct answer to.

The definite parts list I have roughed out is as follows:
-Type R cams, valves and valvesprings (increase hp and slightly increase compression)
-Type R transmission (LSD and shorter gears = faster acceleration)
-Longer intake manifold (slightly increase low end torque)
-A smaller turbo setup (obvious reasons)

Now onto my questions:

1) I was reading up on intake manifolds on various sites and learned that shorter, fatter intake manifolds yield less air restriction in the higher RPMs at the expense of a loss in low end torque. While longer, narrower intake manifolds yield more low end torque at the expense of some air flow restriction in the higher RPMs. So my thinking was that since the b16 lacks torque due to small displacement I can slightly improve this issue with a longer, narrower intake manifold off of a b20. Since I'm not a street racer and I'm actually concerned about my mpg, I'm not going to be driving in the upper RPMs on a day to day basis; I'm not terribly concerned about the slight restrictions. Any restrictions will also be basically eliminated by way of forced induction. I did some reading on the swap and was told that the gasket is different on a B20 and I wouldn't be able to close my hood because of its size and shape. I read that an intake off of an LS, like one off of a b18b1, would work instead. What manifold has the longest runners possible that will fit under the hood and bolt straight bolt on?

2) I wanted to run small turbo with a lot of boost. Similar to how an OEM factory turbo would be (think Fiesta ST). Correct me if I'm wrong but I was looking at a Garret GT2860RS because if I'm correct it's one of their smaller offerings. I know Hondas are known for their strong stock internals. So what would be the max psi I could run on a smaller turbo before I need to buy stronger pistons and rods?

I'm not posting this for people to start arguing so please keep the responses positive and please provide justification/reasoning for your answers.

 

The B16 intake manifold is the best low-end to mid-range power manifokd that you can use. The LS intake wont fit, the bolt pattern is different.

Also, that is a very good turbo for a B16.
