Undecided which way to go for an engine conversion SR20t or a 2.6 rodeo and need to find out what requirements are to get RWC in Qld

Do you mean a modification plate or a safety certificate?

Here's a bit on the QLD Transport requirements. The way to work out the size engine you can put in you car is like this for a vehicle weighing under 1100 kg and having 4 cylinder engine.

Turbo or supercharged:
Max capacity (cc)= original weight (kg) x 2.5

Naturally aspirated
Max capacity (cc) = original weight (kg) x 3.0

So if you work of the weight specified by QT of 873kg for a 1975 4 door (I don't know what your car is??) this will give you a max capacity of 2619 cc without a turbo or 21823 cc with a turbo.

This is know as plating under 'option 3' of the LA1 code. You will also have to do a few other things like fit a 10 bolt diff (TD and later) including brakes and master cylinder. There are some other requirements but most Gemini's already have them covered.

I know someone who has done a SR20T conversion before. I can put you in contact with them if you want. The said it cost about $10,000 by the end - custom sump, modified inlet, wiring.

I think a turbo G200 is the way to go but I'm bias because I'm selling one.

what happend to your 4ze1 turbo?

Thats right. You can go up to a max of about 2.2L for a Gemini. Doesnt seem to matter whether its arse kicking turbo tho, they just work on capacity,...stupid really.

Actually, I forgot to add that info is about 3 years old now...the engineer has more up to date info in his post, but I thought the real dry weight of a Gemini was around 920 kg, so wouldnt that allow you claim more power than using 875 kg?

Id be careful when doing this. I wanted to do it once, but the intake manifold was too large I decided. Then I saw one that had been done, but it was too close to the engine bay in places, a really poor hydraulic clutch conversion, the thing was really uncomfortable to drive, but he had a mod plate on it! Bodgy. Just do your research carefully with an SR20. The CA18 is compact, and will fit in though. Its has less power though

Hey Gene - I haven't converted mine yet (SR20DET) but I was talking to you about it a little while back....what's the way less cheaper option that you have figured out? I'm interested to know anyway??

Cheers

Hey GeminiKing?? - not dissin ya' but what's your background and how do u know so much shit about Gemini's?? When you finished that question tell me more about the CA18....conversion problems etc...sump? ...clutch/gearbox...fit etc....

Why do you have to fit the 10 bolt? DO you mean the Salisbury diff? dont see what difference that would make.
