Bring it up modified plenty of shops up here would mod plate it if it's super clean and done properly

if you can get a thermal camera and check the fuse and relays, very handy for diagnosing faulty relays or high resistance issues. Guessing heat issue in an electrical component.........

Have you checked ecu fault codes? Could be iginotor getting hot, fuel pump failing. Go through proper diagnosis before throwing parts at it.

It seems you gone through and diagnosed everything else. See if you can borrow an ecu from someone local. Got to remember these cars are getting on and things will randomly fail.

Good to hear you got it sorted.

Yeah with heat comes resistance. Run new wires and make sure the 2 signal wires are shielded, will fix all your problems as if you look at trigger/ignition logs you will see it going erratic as RPM increases. PRP dwell settings work fine for the coils. How fun is modifying cars 😅 I think if an Australian with some decent experience on Japanese cars came over they would fix alot of the issues people have over there.

Have had issues in the past with Rb to s chassis conversion wiring with the that dash output not connected and speed needs to be connected for things to work correctly. Pin 53 is speedo input on Rb25 ecu Double check connectors here and back of the cluster.

It's in the loom between the dash and ecu. There is a plug that won't be seated properly as has been mentioned the dash does the conversion from the speed sensor then a wire goes to a connector near the ecu. No need for a new old stock loom. Find the plug and check it or remove the cluster find output pin and run a new wire to the ecu. I'll try and get a picture of the connector in the morning

so Speedo works on the dash but ecu doesn't detect non-driven wheel speed? What ecu? probably using one of the abs sensors for non-driven speed and you have now modified the circuit as some ecu require a digital input not Ac as most abs sensors are. what happens when you reconnect the wire you cut?

Have you tried running a complete new loom to the CAS? may be a high resistance in it. What's the cost to swap to an elite ecu over there?

Wheel bearing or lock bar has come loose. Jack it up and inspect or go to a mechanic

Just roll with it........been here 12 years with same old name. S14/15 would be the go as no hicas or just r33 if you can't find one

Will be issues with fueling if you change the size of the intakes as MAF scaling will need to be changed to suit

Decided late last week I wanted to go to japnats at QR, couldn't go all that way and not drive the event so took the 370. Had a heap of fun but the automatic isn't really up for circuit duties.

Since anything Japanese car related is stupid money have you thought of putting the BMW 335 motor and box it?

Yeah plates are for the next engine conversion

In car from best run saturday 2nd pass edit.mp4

Rockynats is done..... Car went well all weekend. Did 1/8th mile racing and got hosed by a lotus as absolutely no traction. Made 260kw at the Dyno and around 100kms of street driving and cruising. Confused many people what it was. Pretty good event for the first one, even though it rained all today will definitely enter the next one.

thats normal after a swap. So its all together?

Awesome, you will be smiling for a while when you get it back. I'll just leave this here............ https://tremaniacracingengines.com.au/product/ls-403ci-boosted-long-engine/

PM Sent PRP really should supply quality instructions with these trigger kits like the coil kits. Surprised Haltech couldn't solve it.

Maybe get in contact with Ian about a closed deck spacer.......

Car is now registered and done some small drives, it is really loud inside the car but quiet outside. Drives very nicely and no weird noises, stereo is good with Bluetooth music and realdash app going. Fixed everything and went back to the Dyno. Trigger kit fixed alot of things but Intercooler is not happy after a few back to back pulls with 60-70 degrees seen and pulling boost & timing but happy with results for doing everything myself. Will go e85 after rockynats and give it 25psi and extra timing.

Good to hear supercharger is ready. That is understandable to have the sads but doing a great thing helping the locals out.

This is too easy in the US...... Add a boost tee and CAI and run it up on a Dyno jet Dyno 😂 Gtx3071 internal gate, plazmaman Intercooler kit, 1000cc top feed injector kit, aero motive stealth fuel pump, link g4 plugin ecu, 3inch exhaust. Factory airbox with a 3inch pipe to turbo. Plan for a gasket kit and clutch. Leaves plenty of room for more power later.
