I have a coupe with B18C about to buy the peakboost kit with full length ramhorn manifold. I have stock motor just S2 Intake manifold and exhaust but no motor work done. Right now because its stock i only want 250-275 horsepower. I have read B18C can only/should only do around 300hp stock? this is also my daily driver. what size injectors would you recommend? I am also getting walboro 255 pump and hondata s300 to let you know. Oh and will prob get the 57 trim t3/t04E. i think that should be a good size turbo for my power goals and for upgrading later?

 

Your on the right track with the w255... might get some 500-600cc injectors.. depends what you can find cheap.. 300 whp if tuned correctly will be very fun and reliable on the street. your list should include a few sets of ngk-4554 spark plugs. also check out www.ectune.com

are you tuning it yourself ?

 

totally forgot about spark plugs... and no i am taking it to a shop to dyno tune it i guess. its so expensive to do it that way but i dont know how to tune it with the s300. you dont think the 500-600cc injectors are to big?

 

as long as your not using an injector that needs a resistor ox then they arent too big so the cheapest ones i could find 500+ is what i would use

btw a 50 trim would get you to a max of 400whp and 300whp with less lag than the 57....... i have one id like to get rid of that is new if your interested pm me

 

thanks bro on the injector info and as far as your turbo no thanks. i am buying a complete kit. but you think a 57 trim will have to much lag? what about a 57 trim .48 a/r or shoudl i use 57 trim .63 a/r?

 

No, I dont

 

ok cool i went with the 650cc's incase i want more power later and plus with the hondata you can work with the injector size really good and with the peakboost kit it flows so well 650s should be good i think

 

if you plan on staying around 300whp a 50 trim would be fine. If you plan on upgrading in the future (which i guarantee you will) id invest in the 57 or maybe even a 60. the lag difference isnt that big.

peakboost kits are super nice kits. if your gonna do it right get one of those. if i were you id just pick up some rc750 injectors. that way youll have some room to grow later.

ectune is ALOT cheaper than getting an s300.

chipped ecu=100$
s300= 700$

dyno tune=500$

 

thanks stalyn for the advice i did go with the 57 trim and with 650s my tuner told me he could tune out the little bit of lag. i did go with hondata because i am in hawaii and not many tuners here and only 3 dynos on the whole island i think and they are really good with hondata.

 

Smart man..
