bro ddv and x363... i dun really hav experience wif vtec la... playing mitsu engine....
to answer bro ddv... perhaps u can drop by tungchun... i had 2 frens playing b20b last time... on on a EG 2 door... another on a EK4 door... from wat they told me.... stock b20 block wif pistons... head with some work on it.... running type-r cams... n a bit here n there.... using VAFC for tuning only.... never really run wif the EG before... run wif the EK in pasir gudang before... cant catch him wif my 4g63.... his car jump off the starting line n hav 1 car lead.... n all the way till finish line.... btw... both cars hav gear ratio.... n both cars did in tungchun....
lets say u edi hav the block n head done... if following my fren's recipe... would b type r cams, skunk2 intake, s90 throttle body, gear ratio (the car just pull pull pull n PULL from 1st till 4th... never drop out of vtec range!!!)... guess dat's abt it....
for bro x363... i intro my fren to convert b18cr at my mech place... his car was an EG8 auto... total transplant cost with halfcut is around 12k... n dat's abt 1.5yrs back.....
from wat i see... the b20 block wif b16 head hybrid is pretty straightforward n these tuning house had done lots of them... they hav the experience la.... somemore the parts for b series engine are all inter-usable wat....
basically, like i mentioned earlier... the only thing u can use from the b18cr halfcut r the engine+ecu+gearbox+shifer+brakes+suspension... radiator confirm cannot (u'd change to aluminium oso la)... dash will go to the dustbin as its not a hot item dat ppl will source for....
the oni diff between this 2 engine dat i know off is.... b18cr is more rev friendly as compared to the b20 hybrid... but the b20 is a torque machine... i got a feeling my 4g63 boosting at 1bar oso dun hav such torque....
sorry dat i dun hav their address.... perhaps u can try searchin online la....
HV n TungChun hav establish themselves in JB tuning scene la... but HV now u can see more n more sg cars there... evos n subarus.... seldom see smaller cars there d... n there's a number of their old customers going over to Saint Performance (the turbo gangs).... TungChun still doin the normal B series together wif the K series.... whole workshop is all abt honda oni.... lolz....
as for XH n T-power.... i got no comment.... there's also quite a new workshop near TungChun which is actually open by my fren... eXtreme motorsport... i'd say he's not as famous as tungchun... but oso playing wif VTEC.... at least he does hav some achievements in night sprints... perhaps u all wanna pay him a visit as well... but of course... if u ask me.... TungChun still the one la... after seeing both my frens car.... power got... can race... can drive daily.... durability is there!!!
