280z ----> V8

[TexasToker]

Has anyone done this? I have a 78 sitting out back with zero rust and a nice body. It has the I-6 in it now (non turbo) but I think I spun a bearing.

I figured may as well find an old SBC or even a newer LSx engine to throw in there.

Worth it?

look up Darius's car, z with a blown lt1 back when i lived in nor cal, i remember hearing it was switched for an LS, but I havent hung out with the guy in years.

I love Zs. Have you checked out hybrid z forums? They've got people swapping 4, 6, to 8 cylinders and even diesels.

I'd rebuild/replace the I-6.

If you want to keep the I-6, Look up 7m-gte,1jz-gte, and 2jz-gte swaps.Turbo 6 FTW!!!

That is my second choice since it will pop right in.

Chonkey - yea, I am a member to that forum.

rebuild the i-6 or do the turbo swap...it will be better in the long run. a big heavy ass small block will weigh the front down and need reinforcement due to excess weight and torque.

Actually it adds less that 100lbs and with the v8 mounting brackets it slides the engine back a few inches making the car even more well balanced.

The only reinforcements required is a tranny crossmember IIRC.

some of the chevy lsx's are all aluminum, and substantially lighter than a lot of old v8's and 6's

rb swaps are cool and all until you buy parts.

Toyota parts are readily available for the aftermarket and more importantly general maintenance. I mean who wants to wait a month for a water pump.Im not knocking the swap but some of these issue are often over looked.

 

[TexasToker]

So...I am confused...What Toyota engine are you talking about? RB25det is a Nissan engine. The only relation really between Toyota and Nissan is their hybrid tech.

wow surprised about the weight. do you really want something from gm in a nissan? are the dive shafts the same? how about the u joints/spline? talking some cash if you have to fab anything... i'm guessing you will be using the chevy trany? is your rear gonna take the beating or shoot steel everywhere? speedo setup will most likely need a change. wires, harnesses and computers (if used) will need to be customized/swapped. possibly gauges too... it cost a pretty penny to drop a 350 in my s10, and that's far from a nissan.

edit: this only scratches the surface of the swap... also expect to lower the "value" of the car with performance mods.

Sure would.

are the dive shafts the same?

No, the stock Zcar is a little long

how about the u joints/spline?

eh?

talking some cash if you have to fab anything... i'm guessing you will be using the chevy trany?

T350 is generally used

is your rear gonna take the beating or shoot steel everywhere?

No, why?

what about the electronics?

If I go LSx then I will need the computer, if older SBC not needed.

speedo setup will most likely need a change. wires, harnesses and computers (if used) will need to be customized/swapped.

Why would the speedo need to be changed? I am not changing wheel size.

Actually the 350 fits easier into a 280 than an s-10.

lsx + t56 + ford 8.8/9" rear = most badass z in town
