lol it's funny all the hate for the RB20.
OP, if you choose an RB20, just throw a big turbo on it, and it moveeeeees.
just get an RB20 + like a Gt35R + E85 + 30psi boost = SR20 destroyer
RB20>SR20.
RB20 :
6 cylinders
Iron block
better head
Rev's to 8k+ happily
Will take as much boost as you throw at it ( believe me... I have thrown 28pi on my RB20 on a BGS200G and it asks for more ) (will require a TUNE though and ALL supporting mods. like any engine )
Less load PER ROD PER HP- FACT
Cheaper
sounds better
Oiling issues
Parts are NOT HARD TO FIND, and NOT expensive AND SOLD IN THE USA! ( like any RB engine ) Don't believe the BS that you can't find stuff.
SR20
Aluminum block/ head - lighter
Dead engine above 7.5k rpm ( or so i've seen )
4 cylinders
more load per rod per hp
Could make plenty of hp on lots of boost and E85 aswell
More expensive
sounds like crap
easier swap ( if you're lazy )
RB25
Everything the RB20 is except 2.5L
People SAY it can hold more HP, But nobody has bothered to take a RB20 up to those HP levels. HOWEVER there are 650+whp Rb20's.
spools turbo a little faster than RB20
Proven to make HP
oiling issues (rb20 aswell )
Harder to swap then a SR or RB20
custom parts may be required
Transmission holds more power then RB20
as expensive or more expensive than SR20, almost double price of RB20
RB26
Expensive swap.
lots of custom parts required
Revs to ( I've been told ) 9k rpm without a hiccup.
Makes more power/ holds more power then a RB20 and SR20 combined.
2.6L
Some of these engines aren't even old ( like 2002 / 2004 )
not for someone with a limited budget.
Ls1
Torque
expensive swap
lightwieght for engine size
gas guzzler
lots of custom parts required.
not for someone with limited budget.
I could be wrong on some of this so...
