Can RB20DE/DET cams fit in the 20e?

[lucidz32]

Been having trouble looking for cams that would be good for a 20e and was wondering if I could use 20det cams in the 20e (yes I know it is SOHC just wondering :))

 

not planning on swapping the engine, just wanna have some fun with the 20e

And there is the difference. How can you put 2 cams where 1 is?

[lucidz32]

I was wondering if I could use a single cam from the de in the 20e?

 

Since there are barely any performance 20e cams available

I'll keep it simple, the answer is no.

[GTSBoy]

No, you cannot. As I said above. A twin cam engine has the lobes for the inlet valves on one cam and the lobes for the exhaust valves on the other cam. A single cam engine has all the lobes for all the valves on the same cam. There is absolutely no way to make this work going in either direction.

Thanks for the reply, do you have any info on some performance 20e cams??

 

Hehe Howabout the l20?

rather than worrying too much about cams, what are you trying to achieve and what sort of budget do you have?

you can potentially increase power 4-8% by a freeer flowing intake and exhaust for under $5k

[lucidz32]

Hmmm, I am somewhat out of money after doing what you have said above along with a few other mods and just looking for any solution where I can have better cams on the 20e 🥲

 

Sorry if I seem uneducated, I am fairly new to this 🙌🏼

[Duncan]

Cams are unlikely to be a practical answer with no budget. You will need a custom cam ($1k) plus a tuned ECU ($1-2k) and still probably the intake and exhaust mods ($2-3k)

The unfortunate reality is that no budget to modify a non turbo car will result in no improvement (mostly likely outcome will be less power, rough running and bad fuel economy)

[GTSBoy]

Add turbo, enjoy life. If not turbo, add supercharger. If not supercharger, add nitrous. Anything else will be a disappointment. Remember, the RB20E is a very small, very low torque engine designed to do one thing and one thing only. Which is to move cars from point A to point B at the lowest possible speed while minimising Japanese registration tax.

1. Wait until you can save up for engine conversion/off your P plates.

2. Replace engine with Barra

Or LS

What bad luck, imma end it with these words "my engine blew a few minutes ago" imma 25 swap it when I have enough money 🥲🥲

[GTSBoy]

This is the best outcome. You will now not waste any money on that forklift counterweight currently stuck in your engine bay.

Word of advice. If you're a younger gent, don't try to speed up the process by buying cheap ching chong meow ebay parts. Try and find the best bang for the buck and if it takes time, it takes time. 

RB20's have creeped up in price a fair bit but would also be a cheaper option then an RB25. They are fine for 300-400whp. Cheers.
