hey guys ive just replaced the rb20det in my ceffy with another 1 i got it all hooked up and started it and didnt seem to run right it sounded like the timing was out and wasnt firing properly and also pissing out black smoke so somehow to much fuel. i though it might of been an electrical fault since then i have had it at the auto electrician and he cant find any problems in the ecu or harness. the coil packs and sparkplugs are fine to. its possibly the crank angle sensor but thats all i can think of anyway

would any of u guys have an idea of wat i mean or would be able to help solve my problem?

cheers wes :D

Clean all the sensors with contact is the first thing id do and also make sure all the wiring to the sensors is done properly. get timing checked (cas should be dead centre), also find out if your acutally running rich or lean as even tho it spits black smoke it might be leaning out everywhere else.

well all the electrical is fine so im told. but yea im gonna get the timing done tommorow along with the cas. but with the black smoke it wasnt there before wen running my old rb20 and i have tryed a new afm and it made no diffirence but somehow it seems to run better with the afm unplugged :D so yea not quiet sure

32 motor or ceffy one?

you swap the things over you needed to?

um i had originally the r32 rb20 in it and swapped with another rb20 from an r32 aswell so it should run just the same as the last one shouldnt it?

all being well that is but yea it was just a basic swap

hey guys just letting u no i changed the injectors and a new fuel rail and diffirent coil packs now its doesnt seem to have spark :) maybe i havent put a plug back in properly but yea i cant see a plug that hasnt been plugged in.

so im getting fuel ok now but no spark would any1 have any ideas?

    • Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!
    • Curious to see how the SpeedTek stuff holds up
    • The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...
    • Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.  
    • I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
