Hey im currently from a jap background from the UK and have very little knowledge on the v8 front so im here to learn

I have currently managed to obtain an ls1 cheap (c5 setup) and a t56 box, but ive been given a very good offer to sell it and im a bit unsure what to do...

I have been looking at the lq9,l92,ls3 setup's but just want some advice as to whats easier and the better setup. I love the lq9 lumpy idle noise.

What setup do nascars usually use? God i sound such a newb lmao.

Anyway should i sell? or keep the ls1 and put it in my silvia (240sx) currently has an sr20det in.

Or should i keep the sr in and source the part for the lq9,l92,ls3 setup? Or is the whole l92 engine a better setup... urgh im confused lol.

I want the engine to be as close weight wise as an sr, but the loudest most lumpy cammed v8 i can get. With the opportunity to supercharge or turbocharge for mega power... 800bhp+

All info and added knowledge would be much apprechiated as i said know very little about these engines as i live in the UK but would love one

Thanks

The best advice I have is spend at least the next 4-6 months surfing this
particular website. For what you seem to be doing I'd run the engine you
have as it's all aluminum and the LQ4 and LQ9 engines are iron block and the
added weight while not a whole lot would still tax your front suspension a bit
more. The L92 and LS3 engines are 6.2 liters but since they are still in
production it makes them harder AND more expensive to get a hold of. Check
in the hybrids and conversions section to see others doing a similar swap.
For your first swap/install I'd look at a Thunder Racing 224 cam with a 114
lobe separation. This cam can be tuned to have a nice idle sound and will
work well for your future boosted plans. Again I can't stress enough on doing
research, this site has thousands of interesting threads. Also check the
stickies in the GEN III internal section. Good luck to ya !!!

Thanks mate , well this is the point i have an ls1 but not in the car... so debating what to do as ive been offered a good amount/profit for it.

I am checking this site out and its very useful but ive seen people taking the ls1's out to put l92's in?

Arnt the lq9's just 30-40kg heavier than the ls1 though? id just get a fibreglass bonnet etc and itd be fine.

Also i heard over 700bhp the ali blocks arnt very good? where as the cast iron ones are good for mega hp?

Arnt the lq9 engines also cheaper than ls1s? and you cant turbo an ls1 to last can you?

i donno what to do lol.. need more info lol

most people who boost a 6 liter use the LQ4 since it's 9.5 comp instead of 10
like the LQ9. Yes the iron block engines are cheaper since there are so many
available from trucks, etc. Wouldn't you already be adding weight to the
nose of your car with an all aluminum engine ?? So then an iron block engine
would be about 35 kg more in addition to that so it's your call but I'd say no
to the 700 horse limit of an LS1....if the tune is right, timing, fuel system,
injectors, etc. I can't see why you couldn't safely make 8-900 with say a
Borg Warner S475 single turbo with a .96ar.

The aluminum block can handle alot of power, it just takes more to get it there. The lq9 is a common choice when people need to replace a blown motor or want more cubic inches. The lq9 is very easy to get here in the states because there are thousands of them in junk yards from trucks and vans. Also the lq9 can get to 408ci with a 4 inch stroke and the ls1 only gets 383ci with a 4 inch storke.

Unless your looking to make 1,000+ hp I would keep the ls1 for the weight savings in the small 240sx. The iron weighs 70 pounds (32kg said google) With the proper set up, tune, 700hp has done on an ls1 many times.

Do you what your car weighs and what power are you making with the current motor ?

Gymbob

But whats an average bhp range with standard pistons for each?

And with the 32kg on the front end many people do rb and 2jz convertions which weigh more than an ls1 (like a lot more after turbo etc are fitted).

So with regards to the weight im not to fussed, i just want the more reliable engine which can handle more power, doesnt have to be boosted, supercharged would be better, or even just n/a

Just from what ive read 700bhp is pushing a LS1, but doesnt seem to be much for a lq9.

What about an l92 also???

What base engine do nascars use lol

Gymbob

anyone? what about the lsx 454?

NASCAR uses the r07 engine...good luck getting your hands on one.

Budget is something to keep in mind as well. Hell you may be super rich for all I know, but take a look at the sticky thread in the forced induction section. It is named something like "how much does forced induction really cost" the guy made some good points. Not to mention the price for the conversion to put the motor in 240 wont be dirt cheap either and takes a lot of fabrication skills to do. Just some stuff you need to do your homework on.

unless you plan on backhalfing the 240 there's no point in making stupid high HP, got 500 in my LS1 240sx and broken a couple diffs already, LS1 is more than enough to power the 240sx into the 10's. putting the LS1 in the 240 was fairly easy, has more room on the sides and behind the motor than the camaro, wiring is the only dificult part as is with any swap, if you have a LS1 though make sure you have/get a front sump oil pan from a gto to clear crossmember, and check out sikky.com, hinsonspercars.com, chasebays.com, if you don't plan on making your own mounts and doing your own wiring.

I agree with ^ in regards to gobs of power.
what's your budget look like?
My neighbor rocks an LS1-powered 240sx and he drifts in competition all the time. I think he's only around 400rwhp, which is a lot for his lightweight '95.
If you want serious torque, drop the SR20DET and get a larger engine... even an RB25 would be more fun... but it won't passing any smog laws anytime soon

haha ok thanks for the advice sounds good
