hi, i have a b18b in my ek and i want to boost it. i have all the parts and am ready to install but i am kind of worry about the .6 bar(8.7) psi with the stock internals because is a daily driver. has anyone boosted this high with stock internal on a b18b? any personal experience? i am going to do a compression test first before i install it.

this is my setup:

drag manifold
garrett t3 turbo
tial 38mm wastegate(8.7 psi)
greddy type rs bov
2.5" down pipe
vortech fmu(10:1)
walbro 255 intank fuel pump
synapse missing link
precision intercooler
2.25" intercooler piping
2.5" exhaust w/ greddy muffler and gutted cat

 

my homie was boosting 10, till he leaned out a cylinder, but that was due to a injector failing i believe, he got it tuned of course

 

Safe boost level = 0.

Look at the HUGE LS/b18b(a) thread for more real details. Honestly, any boost can do damage... its all in the part selection and most importanly... the tune... ie: ditch that FMU.

 

i'm thing that since the turbo is a t3 instead of a t3/t4 the 8.7 psi won't be forcing that much air as a t3/t4 with the same boost level.

 

you should get something to tune the car with.. hondata chrome aem ...etc... my boosted b18a1 @ 14psi ran 12.0 @116 for about 1yr then the oil pump went out cause of a damn under drive pulley. A buddy is on 16psi running 11.5-11.6 @ 119-121 and its been fine for almost 1yr now

 

i've just picked up a p28 ecu and am planning to get the hondata s300 this summer when i have the money. but for now i was just wondering how long should i run like this before hondata.

 

I have tuned daily driven LS turbo set up on 15psi and they have ran for over 2 years, but they all where on engine mang..

 

im running all stock internals with a small turbo t25 on 10 pounds tuned running fine no probelems i also say get rid of that fmu and get it tuned
