Learnt something new today had never heard of a n/a 20-30 which by looks of this one is running multi throttle body similar to the rb26 covers also look similar , keep up the good work doing well and good score on the granny spec vl Some original photos have not been recovered yet.

I wouldn't buy one. Who needs good oil n water flow Some original photos have not been recovered yet.

Had a chat with my uncle who sold me the engine, he needed the money so he told me it was everything i wanted. It's an RB20 nearly stock. I'm getting my money back next month =.= sigh.... I'll be posting later when I find another engine.

;/ with the money you get back, u should be able to build a 25/30 pretty cheap. heads sell for roughly $250 ?? ---------- Post added 02-01-13 at 19:09 ---------- Quote: Originally Posted by Ant_man [View Post] Learnt something new today had never heard of a n/a 20-30 which by looks of this one is running multi throttle body similar to the rb26 covers also look similar , keep up the good work doing well and good score on the granny spec vl all that effort and i bet that thing wld be slow as f*k

Lol it would probably only be as quick / torque as the rb20e hehe

The M30's 20/30? Actually they were awesome engines - 177 kW (240 PS/236hp) @ 7000 rpm and 294 N�m (30.0 kgf�m/216.9 lb.ft) @ 4800 rpm. Significantly more power than an RB30ET and only 2Nm less torque. Also keep in mind that they were made in the late eighties before RB25s were being made.

so your uncle did the dirty on you? why not just drop a rb25 in it. they're cheap and aftermarket parts are everywhere and cheap too.

You get much more power out of a 25/30 than a 25, if im going to be doing an engine swap. may aswell make it worth my while. im not going for cheapest options like backyard job, but i dont want to spend 20k on the engine.

yeah u dont have to spend the world mate, i bought a complete RB25 with a spun bottom end bearing for $500. fit that to an A6 short motor and you'll be laughing

If you want reliability and easy 400hp go the 25 route !!!!!!
