Questions On Mods

dP3NGU1N

What would you consider worth the money? As with most questions of this type the answer is very relative based on what YOU want for your individual build. Are you looking for the most HP/$ gain? If that's the case I'd forgo NA bolt ons altogether and save up for a forced induction kit. Many people who go FI lament how much they spent on NA mods.

Is your car a daily driver? How much inconvenience are you willing to put up with? As with all bolt ons, the returns are diminishing. Just because each of these pieces individually advertise 10-15hp increase per part, as you get them in combination they start dropping to 5-10hp, then from 3-6hp, and so on.

Unless you're planning to eek every last bit of NA hp out of this engine, those items you've listed are more trouble than they're worth. Especially the pulley. If incorrectly installed, it could cause serious damage to your engine, depending on who you ask. Just do a search on that one, I don't know enough about it myself to truly comment.

Basically, if I were to line up with another 370z with Full Exhaust/Intakes I want to have an advantage on them. But I don't want to pay 2000 to have a very very small advantage.

I do not believe I am going to go FI on this car..It is a daily and I have seen FI kits put people out of their cars for much too long haha. I know of the diminishing upgrades but I have done quite a bit of research on these items and I am still in the air with them. As you said that pulley is a eh eh mod.

Thanks for the quick input!

Rusty

Like it was said. Skip the pulley. Finish up your mods, then go for a tune. Tune last. Why tune it twice.

It looks like you practically have a full build NA setup. Why did you not go for the manifold/TBs?

Rusty

The M manifold doesn't thrill me. Thinking about the Z1 set-up. Maybe spring. Waiting to see other options for the throttle bodies. I match ported my upper and lower manifolds myself. Just never did a write up on it.

Do you see much of a difference with the upper/lower manifolds ported? I am also reading on a debate between 3.9 and 4.08 gears.

Going to have to upgrade the gears soon right ?

Rusty

I did all of my mods then dynoed. So everything was together. Couldn't tell if one mod did good or not. If you do gears. Get a good LSD.

EPs tuning are coming out with 70mm TB's and rjm has an R35 manifold conversion but you have to get rid of the strut bar. Couple other companies are in the "process of making an billet piece. WIsh CJM would create an manifold similar to the badass DE manifold.
