[Fix or Dump (USA Question)]

You pretty much have to swap the auto brake pedal to manual one to fit clutch pedal for some or all the below unless you can go to LVVTA certification place and they say it’s all ok in writing.

 

1) it’s too close together for safe operation or fouls 

2) it shares bolts or bracket with brake pedal

3) WOF will likely flag pedal of car is not automatic on next visit

4) drive shafts are swapped so while OEM are not original 

5) your insurance maybe denied after an accident and they see the pedal

6) firewall is structural and weakens brake pedal mounts

7) firewall needs to be sealed so cutting and putting new holes is also red flag

8) some cars the firewall isn’t the same for auto and has less reinforcement 

 
Do NOT try and bypass or creatively interpret LVVTA rules. Always ask and get it in writing every time.

 

Also any future plans or mods that go to LVVTA may cause issues.

 

i certed my swap a few year later when did coilovers etc. mine was pretty easy as had all OEM parts and even a template for drilling the clutch master.

Hasn't it always needed a cert because of the brake pedal swap? It has been that way for at least as long as I can remember

Nope was free swap for decades  

[Fix or Dump (USA Question)]

The ‘eventually’ part says sell it.

If you don’t have the funds to do it now then sell before it becomes a money pit.

 

Also doesn’t manual conversion require cert etc now, was way easier before.

[What have you done to your car today?]

Nope was pretty good inside, just shims and a few synchros. Seals as well but no bearings or costly things. Parts from partsouq are -$250 shipped.

 

Also confirmed the helical front lsd which I don’t think was in the original box.

[What have you done to your car today?]

Well gearbox rebuilt and setup correctly.

holly s*** what a difference.

Now no gear shifter slop as it had previously even with all rubber bushings replaced.

no whine on lift off either

[VA intercooler fit GR?]

Perrin and other brands say 08-20 for top mounts

 

What do you need?

dunno about anything on this side of the world but the US had a heap with uppipe cats. Only ever a single scroll thing but a major headache for them as they had a tendency to break down and kill turbos. 

Wow that’s a horrid idea.

California does have some crazy emission rules.

 

[Cat in Uppipe?]

Most cars only have 2

Anything pre turbo would kill exhaust pulses so unlikely one in up pipe.

[New limits to modification of vehicles with lane assist etc.]

That’s got to be a s*** time.

 

hHeard the same with other brands saying things verbally but won’t commit to writing it so LVVTA pretty much has its hands tied.

only the coder of the device would actually know how it works and what would through it all out.

[New limits to modification of vehicles with lane assist etc.]

Sounds like anything that moves or repositions a sensor will not be legal or even able to be certified.

 

So things like wide body kits, grills even mirror that have sensors cannot be moved or get get in the sensors way.

Parking sensor should be ok as long as they aren’t used by other systems. Though not sure on how you prove this.

eg

Lane assist

accident warning system

radar cruise control

 

Cars mostly other than wide body likely ok.

 

Utes and trucks that fit large bull bars, winches, longer tray or canopies could be caught out. Since they are the ones historically that get the modifications and are starting to be sold with all the electronic aids.

 

[Rebuild costs / source crate motor?]

5k in 2014 was normal rebuild price with just rings and bearings.

 

there’s a good chunk of cost pulling and refitting motor that won’t be in forged build price. Just assembly would be 7k in labour.

 

You can also waste time and cost measuring up and washing all the old parts on rebuilds. Most places will still strip the bottom end for inspection as you already know the valves hit the pistons.

 

forged is 3k for rods and pistons which you can add to any build.

 

For forged you also spending 7k more for the same power unless you plan on more power. Then you really want ported heads on the list so that adds $$$

 

 

What are you calling a crate motor? Even secondhand unchecked ones are 7k range

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

This would work 3 fuses, and flasher relays do come in the same footprint as these common relays just dont need all 5 connections. They run 2-4 depending on type.

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

 

MSword is slightly better than MSpaint

 

Things in drawing are:

Temperature switch, pump, solenoid.

4 Channel relay timer

Battery

 

Piping not shown

 

 

I'd add:

an indicator flasher relay between the solenoid and relay 4 NO connection for best efficiency and water savings.

Also fuses should go between battery and relay common for relay 1,3,4 based on cable and device size.

Heat-shrink and terminal fittings rather than bare wires etc

 

 

Solenoid can either

sit directly after pump and recirculate water back before pump

or

Sit between nozzles (or nozzle pairs if you run 4) so it alternates left/right or top/bottom for longer evaporation time

 

 

 

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

Pump depends on the jets you use:

windscreen or headlight washers are lower pressure

mist and irrigation are higher pressure

 

Hose needs to fit and hold pressure of:

pump

nozzles

Tee pieces 

one way valve. Needed for washer and high flow irrigation nozzles. Irrigation no drip while not one way do the same.

 

[Nice stock location turbo option]

True cost is not low but no fab work is huge saving.

My EFR is nearly twice the price it was 4 years ago.

 

Does it fit LHD… no idea.

 

Also not twin scroll so 2.5L only unless you want to swap back for rumble with isn’t uncommon.

This may be simple for you in your field but this seems way too techy for me.
ECU control is nice but could you not have some form of super basic controller with a contact thermometer on the backside of the intercooler outlet to let you know if temp is getting up and then have it run for a max amount of time and then shut off

Yes the basic one based on relays in that fuse box could be attached to a temp switch rather than a button.

 

EDIT:

Ok look at pretty diagram a few posts below for what this loooooog text looks like.

 

or

there are 4 relay timers that would stop the system running constantly until temp is low.

 https://www.aliexpress.com/item/4000273267216.html

https://www.aliexpress.com/item/1005004681220191.html

Idea would be to have temperature switch trigger relays eg

connections

Unit power to 12v and ground.

 

temperature sensor connected to NC output of relay 2, and then relay 2 common to input 1

 

relay 1 NO output is connected to input 2,3,4

relay 3 NO output is pump

relay 4 NO output is solenoid if you want that

relay 1,3,4 common are 12v battery via fuse or fuses see below.

 

Working

Temp switch triggers input 1 and then that would trigger input2,3,4

relay 2 then disconnects input 1 since NC becomes open for a time so waits for water to have effect, otherwise it runs nonstop until temp drops.

relay 3 runs pump 

relay 4 opens solenoid to allow water to jets or just does nothing.

 

fuses

Relay 1 only drives other relays, and relay 4 is solenoid so 3w. Pump is whatever wattage but likely higher than others.

 

timers

1 just 1 second as just sets off others

2 time to wait before checking temp sensor again

3 pump run time should be shorter than timer 2

4 solenoid depending on how connected to pump or ignored.

 

would be best to also add switch between temp switch (or unit power) to cabin so you can choose if the system is on or off.

 

Just have to find a temperature switch in the range you want. They are common items for HVAC and for thermo fans in cars so plenty to choose from.

just for anyone in future. Relays with 5 pins

2 pins are to coil that switches the below.

NO is relay that tab that is normally and open circuit or disconnect until relay is active.

NC is opposite to NO, so circuit is connected until relay triggered.

Common is what NO and NC connect to. Can be 12v or ground or whatever you connect to it. 

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

Very nice.

Used plenty of windscreen washers in bumpers before but those save the pissing about with a needle/pin to rotate the jet up and almost closed.

Even on lower lip their low profile still looks good so could run 4 if you wanted.

 

Nothing stopping reusing the headlight popup nozzles either so they would lower from top down towards middle of intercooler.

 

[Nice stock location turbo option]

 

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

Needs more work, but initial syntax in single byte messages

 

missing

• Startup code to announce IC spray unit is working and ready
• A way to return zone count
• Some operational error for water level and flow rate returned values (eg count over what time period, units to be converted to/from)
• possibly a few generic setup codes and hardware buttons.
  • Way to set canbus ID externally but cant exactly have 11 switches to set it. 
  • send packet with configured ID when a button on the board pressed so you can see the ID in a capture.

 

 

Requests codes -> possible replies

 

Diagnostic codes start with 0

 

10###### External Hardware

Used to test physical connections eg cycle would create audible clicking from a relay 

 

11###### Internal ESP32 Hardware

Mostly useless but can log if think there are issues

 

 

 

Operational codes start with 0

 

00###### Manual triggered

 

01###### Automatic (must pass canbus ID for temp as next packet)

 

 

 

Anyone feel free to copy this and build your own version for non commercial use. 

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

Have worked out canbus code byte values.

 

Only thing it needs to have hard coded is ID and the ID to listen for the intake air temp for auto mode.

Auto to intake temp needs high and low byte as second byte would be target temp.

 

Relay cycling has to be preset number or needs high and low bytes so can set default to 10. Since the idea is just to get it to click so you can tell if relay is dead.

 

4 relays can do

Any 1 of 4 zones but spray is on/off by pump

advatange is more zones,

disadvantage spray comes on slow as pump builds pressure at start and drops at end so wastes a small amount of water each time. No delay between zone spray, just one after the other.

or

Any 1 of 3 zones and pulsed by solenoid that return water to tank or before pump until need.
disadvantage less zones. Pump still runs full time.

advantage build up and cut off are instant from solenoid so zero drip waste. Can program in more delay between zones so has longer evaporation time. More cooling less water.

 

 

esp32 can have wifi updates to code so could be DIY setup even on car without access to usb or serial connector.

 

Could preset the canbus ID to a default ID in a known range based on ecu like link, Emtron motec etc.

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

For those with canbus aftermarket ecu 

 

https://www.aliexpress.com/item/1005004213766448.html

and any canbus module

https://www.aliexpress.com/item/1005003450161614.html

Or

https://www.aliexpress.com/item/32757441080.html

esp32 has canbus controller built in so only need the transceiver that does the physical connection. Arduino needs a controller like mcp2515 plus transceiver.

 

Could be programmed for different operations modes.

ecu sends time to run in seconds

unit automatically runs cycles until time is up

 

ecu sends on

unit runs single cycle
 

Ecu sends start and stop

unit runs until stop received

 

ecu send target intake temp

unkt runs, then waits 3 second, requests temp, repeats until temp under target or stops after 10 cycles

Ecu sends status request

unit send running, idle, even water low if senor hooked up. Could be flow meter inline rather than water sensor in tank. If last run had no flow assume water low/empty.

 

Diag options if unit is idle ecu can request

relay # on for X seconds

relay # cycle on of at x hz for x seconds

Relay # current state. Use with above or should be off

Water level low sensor current state 

Water flow meter current reading. Need to turn on or cycle relay for pump using above.

CPU usage

Memory usage

CPU temp

Board temp

Even Wifi status if those are used. could run wifi AP with webpage showing connections and status of each part of unit and connected pump.

 

 

 

canbus dumb version have to trigger each relay.

More suited to meth or extra pump control etc.

https://www.aliexpress.com/item/1005005510819149.html

 

 

Alternative dumb single wire for button. You trigger input1 that runs 10 seconds triggers input2 input3 which run pump and solenoids in pattern as required.

single press with can run a single cycle.

input4 could run different or longer pattern. Or turn in intercooler fan when handbrake is on.

[Anyone interested in intercooler water spray circuit, wiring and tanks?]

https://www.trademe.co.nz/a/motors/car-parts-accessories/performance/electronics/listing/4258707187

option for tidy package. 

can get timer and flasher relays in standard relay size packages.

fuse for pump, solenoids and input even water level sensor would all fit.

Look into V8/9 STI Long runner manifold. Doesnt use the TGVs which should help unless you need to keep the TGVs for whatever reason. Are you in Auckland?

Yeah, but finding one is not easy and would have to swap throttle body and get new map sensor.

throttlebody should be fine to use the 2.5 NA which is 70mm but same outer size. 
7/8 map sensor isn’t on throttlebody so would need new sensor.
