I'll probebly be going the N/A route however I got some questions on power gains and reliability.

How much power could I attain through these mods and how reliable would this be than to rather go F/I? Im also very curious to see if I was to bore out the 2az just to see how much more power we could make. Would it even be worth it and what kind of power gains should I expect?

Bore'd out motor
Cams
Port and Polish with valve job
Injen Intake
MMW Header with S-pipe
2'5 inch Tsudo N1 Catback
NST Underdrive pully
Fuel Engine management
Bigger Fuel Injectors

 

im adjusting your list because something there will be pointless and shouldnt help up in the long run.

Head work( ZPI s2 or s2 head upgrade)
Injen Intake
MMW Header with S-pipe
2'25 inch exhuast with greddy sp2 axleback
NST Underdrive pully/ZPI crank pulley
Fuel Engine management


*wishlist would be a new Intake manifold.

with those you should see some good gains in the NA route with out touching the bottom end.

 

so you recommend 2.25" piping? i'm hearing that 2.5" isn't really beneficial for n/a cars in the lowend/mid.. but makes up for it in the top end.

 

where can you buy the 2'5 inch Tsudo N1 Catback for a good price? and is that exhaust any good compared to like megan or skunk2 catbacks as far as noise level with a header?

 

unless your pushing out over 180hp which we are not and with most of those mods you wont. Yes 2.25 is ideal. you will gain a little hp and tq from the upgrade but you will have enough back pressure to keep TQ and not loose it all completely. 2.25 will be find for top end in combo with a good 4-1 header. the MMW header you wanted is a 4-2-1 which will help you out in the low and mid range. you have to keep in mind what you want in the end either for top end or for mid range. our cars gearing is more for mid range and low and not a top end racer unless you go FI.. for NA 2.25 is should be idea for keeping a good balance of HP gains and keeping TQ around. 2.5 is just rediculous for NA set ups not even pushing 180 hp. it will be overkill and also a waste.

 

Im not informed on this kinda stuff so I was wondering if anybody could explain? Does this mean the block will hold levals up to 450whp?

If you treat it nicly, most surely.
