Check the pins in the injector connectors too, the pic on the first page looks like they might trying to come out the back.

It might pay to check if the halfround is still in the exhaust cam.

Top RB20 Club... do you have over 260rwkw?
r31 25t replied to RBsileighty's topic in Engines & Forced Induction
Just road tuned an rb20det with a kinugawa td06-20g 8cm iwg today. Typical struggle with boost control, but severe porting and flowing of the wastegate seemed to get that under control. Hits the rollers in a month, should be interesting, i can do a comparison with hellaflush7's result! -
Did you re-set timing after re-installing the cas?
-
Hi guys, Anyone got a consult cable i can borrow or purchase? James
-
Yeah, i drove it the other day (not my car by the way i have two in nz) I think the new mazda would eat it! it's a bit of a joke, looks good, but thats it. Going to take it for a drive now actually, go get some pizza!!

Check this out.. This is what was happening on my dyno in the weekend, gutted i wasn't there. http://m.youtube.com/watch?v=4_G6q89QHgM Need to buy another one over here, need something to do while i'm on r and r!!

Is that all your skids up the road?
-
I thought there was a cover over that bolt through the centre of the vct gear, has an oring too. Bolts on using the four small bolt holes you can see.

Sounds like it's over charging. When the alt light is on it usually means they're either not charging or over charging. There should be two smaller wires going to the alternator L and S L = light, S = sense. If you don't have the sense wire connected the alternator will output 12 to 17v, which will cook your battery nice and quick.

Too many of us now to call it an invasion.....

Hamilton, where abouts were you??
-
Yeah, you are just around the corner. Im on sandstone blvd, have to catch up sometime. The 32 (not mine by the way) will be up for sale soon. We're going to build a drift 31, i've still got so many parts in nz so should be reasonably cheap!!

Hey mate, Dwell tables located here...... It's a good read too. http://www.dtec.net.au/Ignition%20Coil%20Dwell%20Calibration.htm

I'm just off the island too, ningi is where i'm living. Been driving a bright green r32 with a bodykit around, looks semi okay, but it's only a 20det with a vg turbo on it. Haven't seen your skyline around yet, must be a bit of a handfull to drive.

I've just moved to bribie from nz. Do you guys meet up at all?
-
I'm allmost certain it's tuning now looking at fuel and timing maps. That boost plot backs it up too. I find when tuning if I run too little timing in power i'll get boost creep. What you've posted shows boost starting to rise as the timing drops off, that means most of the energy is being released in the exhaust. New tuner time.
-
That timing map is pretty average. Looks like a huge reduction at around 5krpm-20psi drops like 3-5deg then back up at 6k. I'd imagine that'd feel pretty flat through there. Did the tuner say anything about the engine wanting to knock?
-
Even 5800rpm may be too high. I tested mine on my dyno and the difference was pretty big, turn off 5600 peak power 300kw at 7000, turn off 6000 down to about 280kw at 7000.
-
When is the vct turning on and off? Are you able to post up the map?

Crazy Noise After Rebuild... Help! (25Neo)
r31 25t replied to Guishnu's topic in Engines & Forced Induction
Gasket between the adaptor plate and cylinder head on 5&6 is where i'd be looking. You've done some good testing there. -
Yes they're just starting to float.
-
Yea ive got camgears somewhere, we mucked around with the switching points for vct when on the dyno ended up leaving it on untill 5600. I will throw one on the exhaust cam next tune and have a play.
-
Update time. Made 300kw on 16-17psi and e85. I did end up with more but i was running out of fuel. I think it's time for a new fuel filter. Will retune on 98 and e85 with more boost a bit down the track. Out of interest what plugs should i be running? What sort of timing no's should i expect up top? Currently it's around 17-18deg. Thanks

What Intank Pump Will Deliver The Most Flow? Nismo?
r31 25t replied to Marko R1's topic in Engines & Forced Induction
Off the return, that way the fpr will hold it at the correct pressure/restriction. It should be a reasonable indication of the flow as long as there are no other restrictions. Eg. Blocked fuel filter crimped line ect.
