hey guys i own a 1990 cefiro with engine mods as follows:

rebuilt rb20det

worked head front facing plenum

fairlady t/b (unsure what model)

high mount mitsubishi td06-19c (part no on front 4917952000)

z32 AFM

huge coola of unknown brand

3inch exhaust

high flow bosch pump

rising rate reg (some chinese shit brand)

mines ECU

ATM im not driving the car atleast untill iam confident its happy,

besides that its ready to drift i have upgraded suspension, brakes, bushes , 2 way diff, 25 gearbox ,clutch

i just need to fix these few problems

while iam good with suspension , brakes and bolt on mods i dont know sfa about engine internals except noise is bad hahaha

ok so heres the questions;

1) iam getting a rattling from the engine over about 3000rpm she drives fine very smooth, i thought it was coola piping on the engine bay but nothings loose or moving

what signs would point to knocking detonation or engine damage? (last thing i need with a rebuilt motor)

2) how much power could this turbo produce ? (when all is proven safe)

3)i have very heavy steering i have checked for leaks and topped up fluid and the belts tight im wondering could it be the pump how would i tell?

4) whats the mines computer like is it worth keeping or should i get a stocky with a remap?

5) it looks stock and sits quiet high .... but will front coileys stop me from getting RWC in QLD (i put stockys in the back already for RWC but i dont have stock front struts)

6) does anyone know a reliable TRUSTWORTHY mechanic on the gold coast

thanks for reading

cheers ..Ben

cud be the pod rattling on the body once higher rpm's make it vibrate more. put some cloth tape around whatever it is on with the body and see if you can hear it as i had the same thing

also high intake temps result in detonation so keep an eye on that. u can use the stock ecu water temp sensor off an rb20 and thread a hole in your cooler piping if you wanna keep track and just hook it up to a water temp guage.

far as i remember there was a thread on here about rb26 intake temps as they have a stock intake sensor and average was 45c. no idea on dangerous but at a guess 55+

just make sure its the ecu sensor not the one that goes to the cluster.

the rb30 may run an ecu sensor aswell so give that a try if you can see it with the same colour/mark wire on the sensor as well as on the loom next to the plug on the ecu.

. the ecu water sensor has 2 wires coming from it, one is a ground or positive and the other is the sensor

a aftermarket gauge has 3 terminals, power + , - (ground), sensor. T off at your cig lighter for +/- powers buy just scratching the plastic with scissors or a knife that isn't that sharp and wrap your connection around there and tape it up

Edited by Dan_J

ok so from the sensor run one wire to the cig lighter for ( + ) power one to the gauge (sensor) then run the ( - ) negative from the cig lighter to the gauge also ... is this correct prob sounds basic to everyone else but just wanna be clear before i start blowing fuses

    • Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂 
    • Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?
    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
