My Love For Rb's Has Been Rekindled

[shakotan-cefiro]

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.

ok will do thanks dan j

.......time for a trip to the wreckers

checked the pod its not that

what is an approx safe intake temp ???

and when is it getting dangerous??

[Dan_J]

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.

iam terrible with wiring and electrics so i kinda need more detail on how to wire up the water temp sensor

Edited February 27, 2010 by shakotan-cefiro

[Dan_J]

. 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

[shakotan-cefiro]

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

could be a million different things making the noise take it to a mechanic, as for front struts s13 is the same

[shakotan-cefiro]

so front coilovers will stop me getting RWC??
