Vtec turbo

[GSHOCK1]

need some advise from tuners.
is't can my stock b16a convert to vtec turbo & running for long term just using :

1. supercharge piston ( 81mm)
2. turbo td05
3.custom Banana ( buy at kedai ekzos RM1300)
4.Afc neo ( for touchup)

intercooler
intercooler pipings
blow off valve

remember also thicker metal head gasket to reduce ur compression ratio

 

[Wira_lover]

ur b16a from which front cut?

the compression ratio needs to be reduced to 9:1 if im not mistaken.currently you're engine should be 10:2:1..If im not mistaken

injector must change also, must install warlbro fuel pump...

 

[SoYouThinkYouCanDrive]

NOT nesseary walbro, skyline r34 fuelpump also can use (100% more than enough to use)
Its the matter of how you tune your ecu/piggyback that controls your injectors to pump sufficient petrol into your engine

i would say get a walbro , opting for 2nd hand units are cheaper , bt many fail further more u got to mod it to fit unlike walbros are drop in, walbro's only cost RM380 about tht, n u dnt have to think of it anymore , do it one shot , u dnt want to boost on the road, then break an engine because the 2nd hand pump failed.

 

[GSHOCK1]

OK...TQ
but stilll not enough about the answer.
1.Injector : take from what car ?
2.Gasket ( now i'm using Mugen gasket (forgot bout the thickness ).Is't ok??
3.In est coast its hard to find skyline r34 fuel pump.What about evo3 fuel pump?

i see, last time i asked is minimum Rm480 for Walbro, thanks for the info

anyway im using SR20DET fuel pump costs me rm160 frm chop shop, using it for 8 months still working like new (touch wood)

to thread starter:
vtec turbo is not cheap. dont simply decide to do it if u have limited budget. moreover, most people nowadays no longer buy used pistons. people buy brand new forged pistons n rods. this can take u further, and also can withstand much more potential upgrades when u decide that beating ur neighbour's satria evo is not enough n u want to try to chase ur classmate/workmate's bmw e30 with 1jz.

for the same reason, better buy brand new walbro fuel pump cos it'll be 1 time investment, rather than buying some chop shop fuel pump, and when u want to upgrade more, u still have to buy walbro.

it might be expensive in the first place, but in the end when u look back, u will feel relieved that u have done the right thing.

as for engine management, crome (software for stock ecu) is extremely efficient. can control big injectors, can control fuel n ignition maps with boost. no need piggyback anymore...

soyouthinkyoucandrive: if local shops sell at rm480, try to look elsewhere. there are many reputable shops in aussie/states that sell at much cheaper prices, and sometimes they offer free worldwide delivery. of course your sr20 fuel pump is working well at ur current level. what if u decide to plonk in bigger turbo, big injectors, wind up the boost? i'm sure u still need aftermarket fuel pump.

i will say wht khoyos said
do it once n for all
u get a sr20 pump for 160 , bt when u start playing with turbo,
its totally diffrent, N/A's arent that easy to break pistons ,
if ur pump fails , puffff on boost :P
further more its not so much more expensive, for new + higher fuel flow + reliability
its better than breaking the pistons or sitting beside the road with fuel pump failed ehhehe

khoyos,
RM480 I asked is BRAND NEW Walbro, not chop shop. thanks anyway

jinkl,
I wrote SR20DET -> "DET"

:)

doesnt make any diff in my claim
wht i mean is go for reliability
walbro = insurance

HMMMMMMM,,,,,,

Bro,

injectors you can use H22A.

But using a turbo on the b16 right, must remeber that vtec cams runs at high duration,set for high revving which means it has more overlap at high revs to keep the pressure.

Turbo applications, you don need high duration cams.i just think you should know theres more that you got to look into and also more parts to replace to ensure you're running a safely boosted VTEC before you detaonate it.

bro, mind to elaborate more on this "But using a turbo on the b16 right, must remeber that vtec cams runs at high duration,set for high revving which means it has more overlap at high revs to keep the pressure"....thanks

 

[AD_EG]

before vtec kicks in,it need to maintain lower duration so that the pressure is contained inside if not during intake the air will push out through the exhaust cause its not shut completely.if you use stock cams and boost it, this might happen.but if you get a set of highlift cams with lower duration it should be ok.

p/s:im too only learning..please correct me if im wrong.thanks.

 

[GSHOCK1]

OK...Now i'm became more confusing.....

its mean using standard injector ,standard gasket head & standard fuel pump become worst even my boost only below than 0.5 bar
