ok, so im about to boost my ef. i have just recently swapped a jdm d15b vtec motor in, and have been piecing my turbo kit together for quite a while now. im hoping to make 200whp on this setup. i know that d series motors are good for it, but im not sure how much boost to run to get to my goal. i was hoping someone here could help me with this. but anyway, heres my setup:

-log manifold
-tial 38mm wastegate
-mishimoto fmic
-hks ssqv blow off
-garrett t25(stock 300zx turbo)
-ebay piping
-arp headstuds
-cometic headgasket
-walbro 255 fuel pump
-dsm 450cc blue top injectors
-greddy profec b boost controller
-2.5" downpipe
-2.5" catback
-oil line kit from stealthmodeperfomance.com
-autometer cobalt boost gauge and air/fuel gauge

also if anyone has any advice for me, this being my first boosted car, lmk. thanks ahead of time!

 

Make sure you get it tuned.

 

well yeah lol, theres a guy in my city thats the tuning guy. does great work, and im using a dyno in nashville at a local car shop

 

You will need atleast DSM 450's for injectors, I didn't see any listed. Depending on how healthy the motor is ~10-12 psi you will make your 200 whp goal.

Also for peace of mind sake, you will want to get an aftermarket fuel pump as well as a 2.5 bar map sensor if you want to run more than 11psi. You can purchase these through http://www.phearable.net/shoppingcar...sors-c-29.html

and as AllmotorEG said, don't boost it if you don't have the money to tune it correctly. Basemap may or may not cut it depends on if you want to risk it.

 

what engine management are you running? if its neptune RTP or hondata S300 why not run a PWM boost solenoid and have your tuner turn up the boost till its at a power level that makes you and your motor happy?

 

yeah i already have a walbo 255 fuel pump, and dsm 450cc blue top injectors, forgot to list em, but i fixed that. but yeah, how do i know which map sensor to get? i havent looked into that at all
im not sure which program hes running. i talked to him a little while back, but it wasnt hondata. may have been neptune, not 100% though

 

1 bar = 14.5psi. Stock honda map sensors are .7 bar which is ~11psi. 2.5 bar = ~36psi

You can wire it directly into your map sensor wiring and you will be able to make over 11 psi of boost with proper tuning and using a boost controller. Omni makes a 4 bar map that plugs directly into the stock location but it goes for ~125 bucks compared to the 2.5 bar map which is 35.

 

so getting one wouldnt hurt anything, just help if i ever wanted to up the boost? if thats the case ill go ahead and get the 2.5 bar, i will never see anywhere close to 36 though

there you can find alot of choices on map sensors as well as the pwm boost solenoid

 

dephtone was talking about this one http://www.phearable.net/shoppingcar...nsor-p-37.html it supports up to 23psi.

i personally run the GM 3bar

 

ill probably get the one he was talking about for 35. i really dont see myself going anywhere near that much boost anyways
