Should i engine swap my 300zx 2+2 For an LS1?

[Speedracer6911]

I just got my car dyno'd and with all my add-ons it pulled 180 horsepower through the tires.. I was like HOW CAN THIS BE?!?!? I understand all the losses but that is insane differential.. He told me to drop the motor and put in an LS1 engine in it and get rid of the nissan engine... What should i do? i Want to get a new software for my car and maybe that will help.

If money is no object, you shouldn't even have to ask this question. If it is...still yes but you better start cutting coupons or something.

Why would you consider throwing in an LSX engine when you have the TT swap

[evildky]

that is the problem with N/A engines, you have to work a lot harder to get any real power gains, if you want to gain more than a few hp you have to swap for a turbo or something more radical like the ls, the ls has been done but the tt is more bang for the buck, and a heck of a lot less work

Ghey.

with intake and exhaust and a 50 shot, i put down 230 to the wheels.. LSx swaps are long and expensive. your vg30de can take a 50 shot all day and if you put cooler plugs you can probably up that to a 75 or even 100 shot with some tuning.

One thing that I would take into consideration though is, parts for the LS1 would be significantly less expensive than for the TT once installed. I don't think that there are nearly as many vendors for the VG30DETT as there are for the LS1. In the long run, once the swap was completed, maintenance and up-grades could realize a signicant savings. If something were to happen to that LS1, it would also be a lot cheaper to replace or re-build later down the road.

^ I concur

What you mean by shots? And mine isnt a TT

Chevy engines belong in Chevy's.

Swapping one into a 300zx would be wrong.

I have done absolutely zero research into this topic. But I have researched putting an LS1 into a 240sx, and based on the same principal. I say **** YES. Then twin turbo that. You'll still have a 300zx TT, but it will be ever so slightly more powerful (understatement).

so yeah, don't take me seriously, but do the research. I am all for an LSx series swap though.

Been done a few times. Did an article on a LS1 powered Z32 some years back and I think I still have the manual on how to do it. The owner provided me with a how-to booklet on how he did it.

He opted to chop the heck out of the crossmember and boxed in for extra strengt. I believe he also needed to cut up some the transmission tunnel as well. From there a custom driveshaft was needed and a few other minor things as well but seemed relatively do-able.

If you really want to do it, I'd personally say stick with the VG30, but if that is what you want I can maybe find it and send you a copy if I can dig it out of my stack of service manuals. But if it was my Z, stick with the stock engine.

ls1 TT = about $10k total for just that. that's assuming u find a ls1 with transmission and harness for under 2k.

install... who knows. prolly 2500-3500? and then u also gotta find some1 that knows how to do it unless u can DIY.

it would be sick. but i'd go the cheaper route and do a vgTT swap

Yeah, but there's a 345HP LS1 on eBay right now for $3900 with transmission, wiring, and intake-to-gas pedal connections. Now, if you start with 345HP, and granted, that is fly-wheel, or perhaps only crank HP, it would be much easier to up-grade later. I'm thinking a lot more power can be extracted before a Turbo system is ever needed. I bet it could be done in the $6 - $7K range. Granted, that is expensive, but as I posted earlier, all the follow-on up-grade/rebuilds will be a LOT less expensive than the VG30DETT.

Still 'ing!

Have you considered a VQ35 swap -- it is being done alot in 240 sx 's -- there is a website devoted to it -- and it is a nissan engine -- relatively inexpensive -- and you get a real transmission instead of the clunky long throw chevy transmission -- i will try to find the website address for you

here it is:

Only if you twin-turbo it

an unlike the NA Z they have many turbo kits for the VQ35 !!!!

You can't even think of all the parts available....

IMO, it is in the eye (or wrench/wallet) of the beholder/owner (I happen to have 3, but no 300zx yet) :

1975 280Z w/ Chevy V81988 Supra w/ Chevy V81988 RX7 w/ Chevy V8

All three were headed for the junkyard when I performed the life-saving surgery on them . The Datsun only had 2 wheels on it when I got it!

[nghtrain88]

an rx7 with a chevy v8? that just COMPLETELY goes against all purist ideas

i second that

[75_280Z]

I get some grief on the "purist" forums for the cars, but then again, the "purists" didn't buy them or pay for them.

If I didn't buy them, they would be appliances, soup cans, etc. by now.

yeah! everyone knows you're supposed to put a small block ford in a RX7 I've seen some very clean 5.0 swaps in the first 2 gens of rz, and one hella sweet buick 3.8T powed secod gen rx7, scotty later swapped to a 2jz

[75_280Z]

Now, putting a F**d motor in ANYTHING, that is truly impure!

i think chevy should stay in chevy and leave the real performance to nissan so get a nissan...otherwise if you change whats inside its a TRAITOR!

[T45]

There is only one V8 that belongs in the Z. The VH.
