G'day I have got a few questions to ask re auto to manual conversion on a r33 s1. I have done a search and can't find the info i need.

Q1 When placing the clutch pedal in do I have to remove the plate on the firewall covering up the clutch pedal assy. Or do i drill the plate using it as a template? I had a quick look today and it looks like i will have to pull the dash out is this correct or am I making more work for my self?

Q2 I bought a spiggot bush from REPCO and its awfuly tight, so tight in fact I can't get it started to knock into the back of the crank. I don't know if I have got the right spiggot bush or is there an auto bush that must be removed first? From what I can see there is a brass bush in the crank and it looks as though the manual spiggot bush should fit inside it.

Q3 Does anybody know what wires i have to bridge out so i can run the as normal using the auto computer? Does the auto wiring harness fit the maunal gearbox or do I have to modify it? If so does anyone have any diagrams?

Cheers any help would be much appreciated. Like I said I had a look throught the forums but couldn't find the answers to these questions. Please help if its to hard to explain please pm me your number and i will give you a call.

Cheers

I know I may be bringing up an old thread but I'm doing something similar on my r33 series 1.5.

Want to know how to remove the auto spigot bush! It's not coming out!

Cheers in advance!

Fill back of crank with grease, Get a brass drift that matches the ID of the spigot, stick the drift in the hole and whack with a hammer.

Science happens and the bush pops out.

Auto spigot was an absolute bitch to get out, either use the grease method, or drill into the sides of it and cave it into itself with chisel and pull it out.

I tried to use a 3 jaw puller on it, but there wasn't enough of a lip for it to grab, drilling into it and caving it in on itself however worked perfectly :)

Yeah it's an absolute prick!

I have done research on the grease method and understand it fully. It seems to work s treat on the manual spigot bush as there is space behind it where the incomparable substance can push the spigot out however with the AUTO one there is no space behind it so I don't think the grease method will work?

Anyone here removed the rb25det auto spiggot using the grease method? I'm starting to think to use a tap or grind it down and collapse - just done want to damage any of the crank.

Thanks guys. So can I confirm something. I've done heaps of manuals before which are the brass spigots. With the auto's they have the steel spigot (pictured here on the outside) with my chisel marks on it.

There is like NO gap between it and the crank. So grease will push this bastard out? post-36645-14283929476667_thumb.jpg

In theory yes, but i did this about 2 weeks ago and the auto spigot was almost sitting flush with the crank, i could hardly feel the lip with my finger let alone get any tension on it with a tool or puller or anything, drove me absolutely insane

I'd suggest drilling one or more holes in the front face of it horizontally in line with the engine to weaken the circle and then caving it in on itself from the top. I tried just chiseling it, but being a perfect circle very tightly pressed into a hole it's incredibly supported/strong and you'll find it will either chip the spigot or your chisel! :/

Wish i knew that before starting mine, almost went insane lol

So I tried the grease method this evening with NO luck I used a 3/8 extension and a 9/16 socket which was perfect inner diameter. It did not budge a bit...think this is because I had a good go a bashing it prior. The extension just kept spitting back out of the socket. Looks like I will drill it out and cave it?

Yes. Um. What? My 9/16 socket is 20mm OD. As far as I can recall, the OD of the auto spigot is ~20mm and the ID is significantly less. So how the hell is any 9/16 socket supposed to fit inside the auto spigot bush?

From what I'm hearing, it sounds like THERE IS NO SPIGOT BUSH installed in that crank.

Hey man, have a look at photo above.. That is the 10mm deep auto spiggot is it not? And my apologies all it was a 13mm socket. Edited by H@ME

All done.. Manual conversion completed. Used a 3mm drill but and cold chisel to remove the auto spiggot. Used a 32mm hole saw for the clutch master in flywheel. Was perfect. All done now. Wasn't that hard!

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
