Engine Choice for my Project Car - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

BrianG701 · 10-25-2008, 01:52 PM

I'm building a Lotus Super 7 mod clone, I was gonna put an SR20det into it, but then I started searching around and looking up engine prices. I found that the RB20DET is substantially cheaper and makes just as much if not more power. So my question is which of these engines do you guys think will be better (sound, and unique factor incl.) for my 1300lb project car and why?
Thanks

Mangudai · 10-25-2008, 01:55 PM

rb20 is a waste of time IMO. Your better off with a rb25 if your looking to go that route. JMO..

If you are going for sound and unique factor.. an RB20 sounds goood.
This has been talked about time and time again...

RB20...
PRO- 6 cylinder. sounds goood. price.
CON- harder to find replacement parts for, some of the more rare parts are expensive. harder swap/more is involved.

SR20...
PRO- availability. aftermarket and OEM parts are easier to find. direct drop in swap. saves more gas than an RB.
CON- more expensive motorset. JDM tax. only 4 cylinders.

edit:
i forgot you werent putting it into an s-chassis.
so the comments about the swap dont matter.

Nikeboy355 · 10-25-2008, 02:50 PM

SR20 all the way...

I would run a lightly modded 300WHP setup which will be plenty fast for that chassis...
And very reliable and cheap to repair...

An RB20 is going to weigh much more, and be much longer than an SR20. Iron block vs. aluminum, and the RB is just a really long motor for only 2 L of displacement.

It's going to be the pretty cheap weight reduction when looking at it from that standpoint.

SidewayZ-s14 · 10-25-2008, 04:33 PM

Id say SR20.
Weight to power, SR all the way.

GoodLuck!

BrianG701 · 10-25-2008, 08:10 PM

Well then I guess I',m stayin SR thanks for the opinions guys

Jonnyblaze · 10-25-2008, 08:14 PM

Why Nissan?

s13 @ fullboost · 10-25-2008, 08:29 PM

just do some overkill and get a Ls2 =]

irax · 10-25-2008, 10:23 PM

for a bad ass sound do a vh45de

for performance and light weight, a built up sr22ve would be great.

s15specR · 10-25-2008, 10:39 PM

1jz, cheap, 6cyl, and parts available also big power easy

Jonnyblaze · 10-25-2008, 10:40 PM

I don't see why anyone would choose any of the above listed engines over an LS1. (except for the LS2 of course)

Fonix36 · 10-25-2008, 11:19 PM

ls2 i have to say for something like that

JRas · 10-25-2008, 11:23 PM

did you happen to look at the weight of a RB20? compared to an SR20

FIlthy 24O · 10-25-2008, 11:26 PM

ka-t would always be an option

TPS240sxS13 · 10-25-2008, 11:56 PM

^^^ I like that idea. Why not use Nissans red-headed step-child of a motor? <(^^')>

id be down for that swap in that sorta project, but he already mentioned that he'd lean towards the RB because the SR is more expensive. Ive talked to a guy who does LS1 swaps and the price to do a SR swap is way less than LS1

jrocslider · 10-26-2008, 12:07 AM

2871R SR

responsive 300hp in that car would be crazy enough

lttletimmy · 10-26-2008, 10:17 AM

You might be hard pressed to fit a v8 in a caterham/LoCost. If you can find one, the ecotec LNF engine is a really, really good choice for those cars but and SR would be pretty interesting to see too!

Agreed. SRs are only expensive for broke ass 240SX owners. LS1s still go for quite a bit.

A 5.3 would be pretty affordable, but you still have to toss some mods on it to really get it to wake up.

A VH45DE would be a fun choice if you only wanted about 300 rwhp, as the engines are dirt cheap. Not many engine mods available though.

**ThatGuy** · 10-26-2008, 03:55 PM

The OP already made up his mind.

We don't need ANOTHER SR vs. KA vs. RB vs. VG vs. VQ vs. VH vs. LSx vs. Flux Capacitor Thread.
