Current Build Up Of Rb20

[Drakey]

Hey all,

Currently building up the rb20 a bit.

So far ive put on a new turbo, GTR injectors, and afjustable cam gears.

Ive also had a new exhaust made up for the turbo.

The problem i have is, i tried cranking it over last week and i had nothing.

I did a bit of research and realised i had put the fuel hoses round the wrong way, which i have heard is a common mistake.

i have fixed that and thought i would try crank it over again....

It cranks a couple of time and then all of a sudden feels like there is something stopping the cranking.... like its pushing against the starter motor.

All the lights on the dash go dim like its really struggling.

All i have changed since it started cranking bad is the new exhaust and the fuel lines.

Has anyone come across a problem like this? any thoughts?

with all this cranking... what state is your battery in?

Are you getting spark & injector pulse?

check the electrical connections on the starter motor. Mate had a problem recently where everything was going dim and wouldn't crank over.

Hi Guys,

Yup, all cranks fine no problems at all... then all of a sudden struggles.

Then if a give it a second and try again i have the same problem.

I must admit i havent checked the spark or the injector pulse as yet.

How do you check injector pulse?

what ecu are you using?!?

[Drakey]

Stock ECU at the moment....will be getting the nistune put in this week

[pipster11]

did you put the gtr resistor pack in?

sounds like maybe the bigger injectors are flooding the cyls maybe

try taking the plugs out and cranking, see if anything shoots out too?

if it cranks and stops even with no plugs in then its the starter motor

I assumed you had a ECU setup and configured for the injectors... Silly me!

I wouldn't be trying to start a motor with injectors it is not tuned and configured for.

I'd be surprised if it fired @ all to be honest.

Hi guys,

nope i honestly didnt think it would start myself but i thought it was worth a try.

It goes to the tuners tomorrow and i was hoping if i could just get some kind of life out of it i would be happy.

My thoughts are its flooding like to no tomorrow.

Ill take it to the tuners tomorrow and hope that there is no problems!

Thanks all.
