Rb20Det Converted To Na.

[skyline32sup]

Hey SAU.

Whats the go with the RB20DET's that have been converted to a Non-turbo. I know it has low compression, but i really don't have alot of time to read atm and was wondering if people could give me the run down on it? I can't really find anything that tells me what i really need to know, I just don't want to get one and then have it blow up due to it having low compression.

Cheers.

it wont blow from having low compression, im sure there is plenty of non turbo 20s out there, this would be easier to use than trying to convert a DET to DE specs

won't blow up from having no compression.

may blow up from having to rev it out to redline everytime you take off in order to keep up with the granny in front of you in her yaris.

the stock rb20de makes 114kw at the flywheel. a DET with no turbo would probably make about 85kw at the fly if you're lucky.

If you don't have time to research/read I'll make it very simple.

1. If your doing it for legal reasons (ie P plater can't have a turbo, found a nice cheap det and want to convert to de) - Don't do it - If a cop pulls you up and sees the engine plate says it's a turbo model, even if a turbo is not hanging off the side, you will still get done.

2. If your doing it for some other weird reason -> to be cool/different/rallying with 2lt n/a requirement - Don't do it - if you search turbo to na or det to de you will see from the people who have done it in the past, it is the most annoying car to drive in the world, marc is not exagerating, you will struggle at every set of lights just to get the car moving, you wont be able to keep up with traffic and it will run that rich you will probably only get 200kms to a tank AND you will have higher maintenance costs ie - spark plugs, oil, etc because they will foul a ton quicker.

Summary - Don't do it - find another way.

it would win an award for being the loudest slowest car ...... and get beaten by chicks with auto mirages!.......

[Captain Natro]

Haha at present my natro 25de holds the record for loudest slowest car lol, but yes listen to mar

[WMDC35]

It'll run fine, even the standard compression 20de's are pretty lazy and due to lead booting mow the gas more than a 25de, may blow up from super revving as people say, the auto 20de c33 I had would shift past redline at 7600 and I still couldn't get in front in merging lanes against pussers that were probably not trying that hard to stop me

[Gerg_R31]

wtf did WMDC35 say? seriously had better, unwanted conversations, with smacking out drug addicts, that made more sense then that

lol removing the turbo from rb20s is about as usefull as tits on a bull

[ANT_32]

If you really want to do this I have everything you need. Including all plugs for blocking off turbo lines

[skyline32sup]

Thought i replied, not doing this lol thank though.

[Captain Natro]

don't encourage him lol, glad to here ur not going down this path. unlike a guy at my local supercheap

[Manuel Kasko]

Do it!

Nick just wants to be the fasterestest NA on the road!

Some say he once did a skid

Other say it was just his fan belt

Who are we to judge

[Captain Natro]

upshut daniel, as much as i back natros this is just dumb. id love to see a dyno sheet of a rb20det converted to NA.. thatd be assuming it can turn the rollers lol.

*also as a side not I'm quite confident in saying that the fasterest NAs would either be gregs rb26/30 r31 with the itbs or joels caged up 33, was quick at the motorkahna anyway.

[Manuel Kasko]

How much power are we talking these cars are putting out

[Captain Natro]

when i say NA I'm talking rb30 or smaller not like vh vq or vg engines ,think gregs made around 180kw at the treads but with a nice looking power curve, joels dosent make a lot of grunt but is fully stripped and has a fair bit of suspention work done (+ he's not a bad steerer some some of the lap speed could be from that)

How much power are we talking these cars are putting out

[mad082]

i know of a rb30 (single cam) that got into the 13's. the most power it put out was just over 170kw. was seriously worked. reved a few thousand rpm higher than stock.

[Gerg_R31]

Mine currently makes just under 170kw, makes power all the way up to 8200

but since i have learned of new tricks which ill be doing and going e85 at same time

[bozodos]

read your build thread, quite fascinating and kudos for doing it differently!

have you thought about shiteloads of comp + methanol perhaps?

[Captain Natro]

would love to here it at 14:1 on meth

[Jamie86]

Just to clear this it does work

I have r33 det converted and drives perfect probly a but Quicker then a sv6 thats with the turbo 3.5 exhaust and more the enough to have fun in

I can Take video evidence if you have douts

Runs a little rich up high in rpm usually about 5,6 thousand, but still get 450kms to tank and I have but of a lead foot

So of you wanna do it it's easily done
