Best bang for your buck mod combo
 

Sold my 04 STI and got back into a Z today. I'm trying to gain as much midrange torque as possible. From reading on here the last few years, Im thinking a Motordyne intake manifold paired with some HFCs would be a good setup on the cheap. Would be nice and quiet when I want it to be but would still put a smile on my face going WOT.

I'd appreciate any input. Especially from those who can speak from experience. Thanks.

Think you'd go way cheaper and be better off with post MAF tubes, new filters and test pipes. Pretty sure the post MAF tubes and new filters were shown to give better low to mid end power compared to the stillen intake which gave gains in the high RPM's.

You can get ........ ones for 200 some odd bucks or find some good used HFC's or test pipes here on the sale forum, so that'd be less than 500 bucks total coupled with tubes and filters from Z1.

test pipes are the best bang for the buck imo

Test pipes but you will have to get a tune. If you don't it will be throwing codes all the time.

+1 for test pipes, definitely best bang for buck mod. Other than that, fast intentions catback seem to have very good gains as well!

Manifold, HFC, Catback, and tune you're already near $3000 if not more.

Spend a few more and get this.

This is what i call a "real" best bang for buck.

testpipes
post maf tubes
lightweight flywheel
4.08 gears

High performance driving school :p

K&N Drop ins, tubes, motordyne (or DEpointfive0) intake manifold, used Nismo cat back (from a Nismo Z). Block off all the resonators on the intake tract...


You'll have a big fat torque curve (relatively speaking) and plenty of intake howl at high throttle input to make lots of noise for you without being any louder than stock in normal driving. Peak HP will be in the neighborhood of 290-295 WHP with area under the curve being hugely improved.

Then you can do some HFC's later.

Best bang for the buck.

1. K&N panel filters (~$100)
2. Cobb (or similar) smooth intake tubes (~$200)
3. ebay test pipes (warning -- raspy!) (~$75-$150)
4. Nismo (pass on the S-tune, get the OEM "take off", picked up used -- ~$300-$550)

Total cost: Under a grand

Note 1: That is actually a bit lower -- add another 3-5 whp/wtq for the tubes. That dyno is before the tubes were added.

Note 2: If you are worried about rasp, pick up a set of used resonated test pipes for a bit more $$.

Note 3: Most of those gains were from the K&N and TP's mods, so if your budget is really tight, just go with those.

Oh, and some lighter weight rear rotors... Those will add WHP as well.

Budget's around a grand. If given the choice, would you guys go with a cheaper intake setup or the Motordyne manifold? From what I understand, the manifold on a stock car gives big midrange gains.

Definitely going with HFCs to stay legal and open up the exhaust a bit.

I wouldn't recommend changing the IM without tuning. You will almost definitely gain mid range but lose top end without tuning.

HFC's will net gains similar to TP's. Again, if you are leery of rasp, get resonated HFC's.

Thanks. Didn't realize you needed tuning with the manifold.

You don't....

Tuning is great for everything, you will always get more performance out of a tune.

There isn't a single N/A mod (within certain limits and with certain notable exceptions) that REQUIRES a tune.

Certainly nothing discussed in the this thread requires a tune.
