hey guys...

how much would this conversion cost ( rb20 in a 180 )  say from a r32 f/c or a cefiro f/c & i'de be selling the sr20det + gearbox...

any are there any issues with this conversion ??? thank you!!

A 5 speed manual RB20DET 1/2 cut with the front brakes sells for $2400. You should be able to sell your motor + g/box + loom + ecu + afm etc for around the $2000 mark.

The motor physically bolts in, you use the R32 radiator, crossmember, g/box mount, power steer pump. While you are upgrading the motor, I would suggest doing the 4 pot caliper upgrade to the front.

You can't use the engine fan as there isn't enough room between the fire wall and radiator support, so thermo fans are used.

maybe seeming you will get some decent $$ for the SR20DET, get yourself a rb25det...

but going from sr20det to rb20det, same as above... why?

I am currently doing the conversion myself.. from sr20DE to rb20det any questions... let me know

Not an rb20 please. Get something decent like an rb25. Or better yet dont do a conversion. The sr's are well known for their ability to double their power with bolt on mods. with over 2 grand you could get a few parts that would go on that would make decent hp, like a frount mount and a new turbo, possibly injectors though you would be streching your budget.

the issue..

why the hell would you swap out an SR20 with an RB20?

the SR20 kills the RB20 hands down, and your 180 will be waaaay to front heavy with an RB20 anyhow.

I'd stick with an SR20 all the way

I have a RB20 in my S13 hatch... great motor and the car has excellent handling with my Kei Office Type XT footwork... don't mind what people say about the RB making the car front heavy. Check my signature to see the details on my car.

Granted... if I had a SR in my car originally... vs my original KA24DE truck motor... I'd just sell my S13 buy a used GTR.

      Need AC Compressor for R32

      By joshuaho96 · Posted

      Aren't these run off of high voltage in OEM applications? Like 200+V. Or at least 48V in mild hybrids. At ~18,000 BTU ballpark nominal capacity the power draw is at what, 2.2 kW? ~185A is a pretty crazy amount of amps. At 200V it's only 11A. The 70A nominal kits with up to 100A peak draw I see for stuff like classic Porsches have pretty substantial compromises like shutting off at idle and not actually managing to keep the interior cool in hot conditions because they can only output like 6000 BTU. IMO if I had to pick what high amp draw component to retrofit to these cars I would start with the engine fan, not the AC compressor. You need an ~850-1000W brushless fan, something like this: I would love to see the data but I would bet that whatever you save by running the AC compressor in a more efficient regime with an electric motor you're probably losing to conversion losses anyways. It's not really like a clutch fan where you're losing power all the time even when it's nominally disengaged and it gets worse as it engages because the envelope tracking isn't that precise.

      I'm wondering is the Toyota and Mazda "collaboration" could see that new Toyota ???G20 ??? turbo engine that they have been showing off recently into a future MX5, apparently it's good for 400hp out of the box That could easily, possibly, be much better than the last collaboration between Toyota and Subaru with the boxer engine in the twins
