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?

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?

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

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

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.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Should have asked what is the car?

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.
