Thread: 300whp sr20det or 300whp chevy 5.3l in a 240sx?

Hey guys I'm wanting opinions on what I should do..lol I have a 240sx w a Sr20 in it..I'm wonduring would u like a 300hp Sr20 or a 300 all motor 5.3l? Trying to decide what to do..it would b easier to keep the Sr and build it a little but having 300hp all motor would b cool too..any opinions? Lol

SR20DET keep it Nissan.

Several trains of thought.

Keep it nissan.

SR20 will be lighter.

Chevy has MUCH more aftermarket and cheaper parts if you search.

All motor means you can boost/spray/supercharge later for even bigger gains.

Personally, I'd just pick the one YOU want the most. Our suggestions are just that, suggestions. In the end its your car so do what you want...not what a bunch of random azzholes on a forum tell you lol


IMO, I see a lot more options with the chevy motor in the way of power increases down the road.

It all depends on you man. If you have the $ for a v8 and wanna be different then do that...
but then again if you already have an sr, there's no sense in getting rid of it if it runs

sr20 all day

sr20, t28, 15 psi, and a tune and your at 300 with an exhaust.

there's no replacement for displacement

Why the 5.3 and not an LSx?

One of the best and most forgotten statements in the 4cylinder world.

A gut was gonna trade me my Sr for a 5.3..everything except the tranny..but a blowoff valve sounds great and the engines already in the car..lol

2jz or 1jz swap

if engines already in the car leave it lol

Realistically your going to keep the sr20 so sr20

^ lol way to be blunt

and answer ur fone foo

SBC. If you do everything to the chevy engine that you dream of doing to the nissan, you'd rip the rear out of the car! It will be nose heavy with the sbc, but that would be a fun car. Kinda like a tokyo drift on opposite day!

LM7 isn't worth it. LSx would be.

Well a guy wants to trade me a 5.3 for this Sr20..lol y won't a 5.3 b worth it? It's 300hp out the box..that sti and evo numbers..lol stock..lol

Are you even thinking about the time, effort and cost of the swap?

The lm wouldn't be worth the effort compared to and lsx. If you're wanting a v8 swap, the ls is the way to go.

+1, LM is a heavy POS compared to an LS.
