L24 vs L28ET

[Zed Head]

I was more concerned about driving high in nighties...

 

Anyway.  Back on topic.

I just realized I might be on the wrong forum with this question. I just feel like Hybridz will garner a bunch of "RB26 intercooler stance JDM style, yo!!!"

Hybridz would be good for you once you decide.  But those guys tend to know what they want - more power, more speed, better handling - so maybe not be much help deciding.  Restore here, modify extensively there.

 

You won't find much stance or drift over there except for how to go faster low, or how to make more power for drifting.  There's a thread on swapping a stock turbo n to early Z's, well read since most people have problems with it.  Just saying, it's not like a transmission or diff swap.

There are a lot of considerations for going L28ET. Fuel tank? Fuel line size from the 240z tank? Find a 280z Tank? Fuel pump? ECU and harness? Is the donor engine and turbo good? Its not a plug and play deal! I can tell you there are always unintended repercussions from getting off the beaten path. Been there, done that. It will be cheaper by far to get what you have running and go from there. From someone who hasn't driving a Z regularly in 20 years or so. Get it running and enjoy it, don't try to "reinvent the wheel".

That's how he rolls. Let it go.

 

Don't tell me you haven't considered the same thing on a warm summer evening...

The fuel requirements for FI motor will cause a lot of work and money. It's more than if you were just going L28et from a L28e motor. Than you have the wiring .

How much work do you want? If your power hungry you better go L28et

On the transmission swap, FWIW, Nissan went with the T5 in the turbo cars because it is more robust.

The NA 5speed will work for a while, but you will eventually tear it up.  I think the Nissan T5 was rated at 260 ft/lbs.

 

The OP does not sound like the kind of guy who will be happy running the stock 6 lbs of boost if he goes with a turbo swap.

Then he'll want to read this thread - http://forums.hybridz.org/topic/50208-the-ultimate-l28et-guidewhat-you-need-for-350whp/

 

Even trying to stay cheap, stock and NA, I easily went over $3000 spent to get mine in good running condition within about a year (I drove it anyway in bad condition for that year).  The nickels and dimes just add up: master cylinders (brake and clutch), slave cylinder, wheel cylinder, calipers, booster, brake lines, tires, lug nuts, fuel pump, exhaust manifold resurface, gaskets, clutch set, injectors, more gaskets, shocks, etc.

 

These engines are so durable that, unless the camshaft has gone flat, you can almost always get them running.  If he goes out and buys a turbo engine thinking he'll drop it in and be driving, his budget's probably shot before it can even power itself out of the driveway.

 

 

Edit - sorry, just feeling blunt.  Nothing wrong with getting information for a plan...

 THAT was useful. Thanks.

I think I'm doing all of this anyway, hence my earlier comment about putting money into one engine, and then doing it again.

This is something I want more clarity on. I have found some comments about the wiring harnesses being incompatible, but I'm wondering if someone makes an aftermarket wiring harness specifically for this purpose. This seems to be a popular conversion, at least as popular as the RB26 conversion, so I'm curious if there are people making kits (like there are kits for rear disc breaks, for example), but I'll dig around on the HybridZ site for that.

If you want to go with an L28ET, I would suggest buying a runner, drive it home and then do the swap. Anything else is truely high risk. All these EFI systems are getting old and you shouldn't compare them to any EFI system today.

 

I wouldn't limit my search to an L28ET with a manual transmission. If you buy an FS5W71C you will have enough parts with the 71B to do the swap. There are some modifications, but there is plenty of forum information to help you through and you can always ask.

The 71C is considered by many to be a better transmission than the T5, even the one out of the 300ZX.

 

Mmmm. Why not a 300ZX twin turbo...... Now where thinking out of the box.

I have 2 l28et's here in my shop, if I ever get around to trying this swap I will not be using the stock EFI. I will go Megasquirt and spend several years sorting it out, but that is standard operating procedure for me.

I think I'm 90% certain that i'm not going to make any decisions in the short term. Maybe down the road, but not before I get the car stripped. I feel like the right time to do lock this down is when the car is totally dismantled, but right now I don't think I know enough about these cars to go down this road.

I'll revisit the issue when the car is apart. Thanks for the informations guys! Feel free to highjack the thread now.
