L28 + turbo = L28ET??

[Fuzz260z]

hello, i am currently entertaining the idea of buying a 280zx for $200(aussie), i havent looked at it yet, but my mate said shes pretty rusted. i already have a 77 260z, and want to get some real performance out of it. now what i was thinking is, buy the 280zx do some work to the engine, turbo it and all that jaz, then once if got it all ready, drop the engine straight into the 260z. now before you guys start yelling at me and saying "just buy a L28ET dumbass" remember, i live in australia, and have only ever seen one L28ET for sale, and it was selling for 13k. i dont have any real details on the 280z engine wise, i dont know what head or block it has, but i doubt it has the p90 head or the f54 block, which is what i belive they used for the L28et(or is it the n42 block?).

what i wanted to know is, if i do some work to the L28 engine, and turbo it, will i be able to get the same sort of performance from as the L28ET would give? can the engine tolerate the boost, will the head work just as good even though its not the p90(i will port it of course) all that kinda stuff. anything you guys know is helpfull. cheers

Hi Fuzz:

Almost anything is possible - if you are willing and able to spend the time and money.

Many people building high performance L28's prefer to us the older N42 blocks, because the coolant circulates better and the cylinders are cooled in a more even fashion. So you could use that block for sure.

The L28ET's ran dished piston's with large cc combustion chambers - to attain the most volume at the lowest compression ratio. This allowed the most boost to be applied without engine knock/pre-detonation; more boost results in more HP than less boost with higher compression to begin with. So you would want to use dished piston's... maybe you can get a set from your local Nissan Dealer, and if not, you would want to spend the money on a set of aftermarket forged pistons.

The P90 head would be the best if you can find one. If not, no super big deal... you can rework almost any of the heads - but you would want to attain the largest possible combustion chamber size along with the largest valves you can install.

The L28ET's used Turbo Rod Bolts, and the higher capacity Turbo Oil Pump (for more flow to/from an oil cooler). You could use the ARP Head Bolts / Studs...and order the Tubo Oil Pump from Nissan.

The L28ET used higher flow Fuel Injectors..... you can order them from Nissan or buy in the aftermarket.

Lastly there are several modern Engine Management Systems that are far better than the original one's Nissan used - you would want to use one of them anyway....

After that - it all depend on how much HP you want to make - the stock L28ET's ran about 8lbs of boost and did not use any intercooler - you can easily run 11 lbs with cast pistons and an intercooler - or go higher with forged pistons and a larger intercooler. So 225HP to 300HP is a pretty easy goal to attain.

I'd guess you would spend about 6 months planing, detailing and gathering all the stuff you would need for the engine build - and perhaps $8K to $10K. Then you'd have to spend a few more dollars upgrading the rear-end and half-shafts, upgrading the brakes, and running wider tires etc.

That should give you at least an idea of what you would be looking at...

FWIW,
