I completely understand the N/A compared to the Turbo'd 135i. Of course it will pull more power with a couple bolts ons and a tune than the Z due to it already being turbo'd. With the 135i being turbo'd, bolt-ons and tunes will be more effective than to an N/A. That is a reason why with bolt-ons and a tune the Z will push 320whp 270tq and the 135i will push 360whp 400tq with the same.

If you were to compare straight power to power while boosted:

135I twin turbo with tune etc.: pushes 420whp and 450rwtq when running 20lbs of boost. I could see this engine fully dressed/rebuilt and push 500whp 550rwtq MAXXX... The lack of the .7L worth of an engine and already being closed to max with power after a few bolt ons and an updated tune is kind of upsetting to me atleast. It doesn't leave room to work with for real power.
You would have to drop a bigger engine but then it would make the car too heavy in the front.
370z twin turbo with tune etc: pushes anywhere from 550whp 500rwtq up to 900whp 850rwtq. Depends on what TT kit with add ons and what other mods are done. I know Bullitt who is selling his GTM Stage 6+ TT kit, I believe he pushed 1000whp on a 4.5L stroker. I believe Carbon Z is making a TT 4.0L stroker to push 1000whp+. From what I talked to him about his engine can withstand up to 1400whp, but his fuel system and only has 1200CCs to work with making his engine safe to race with at about 1000whp.
You could put as much money as you do into the Z into the 135i and the 135i would never catch up to the Z.

I guess you are looking at whether or not you're wanting to build a completely custom car for you, or being limited to only Forced Induction without doing a complete engine swap.
They are two different vehicles.

The 135i you can get some good power easily and cheap compared to the Z. The 370z will give you a HELLL of a lot more power over time if truly investing into a custom vehicle.

But for power in a Forced Induction state, the 370z will be more expensive, BUT WILL WIN.

My

Yeah it costs more for the 370z to have twice as much power as the 135i but the bang for your buck doesn't start right away like with the 135i.
370z mods are out of pocket completely and are dressing a stock N/A engine for boost.

Unless you go through bulletproof lol... they finance parts now lol
