Does anyone know what the main differences are between the standard L28ET we got in the states, and the JDM engine?
I found a car that I would like to get the engine out of, or possibly build if I had the money. The guy has this ad.
http://phoenix.craigslist.org/evl/cto/893129557.html
Talked to him, and he says that the JDM was set up to run 10lbs of boost.
He does not know what block, or head it is. I am more concerned with that information.
But, I am out of town for the next 5 days, and am curious if anyone can tell me about the JDM.
Did a search, lol. But, either I am too lazy to read through countless pages to find the answer, or I can't find it.

i thought jdm engines were like L20 or maybe l24s if i recall. could be wrong.

hmmm... was there a turbo option even for jdm? i know eurospec did at least an i think their efi was a bit different of a setup

There was no L28et in Japan. The turbo 280zx they had, had an L20et. The L28 was always non-turbo over there. Unless that guy swapped on his turbo stuff to the L28, he's blowing smoke.

a 2L L6 wow, that is a small piston....

Kinda like an RB20DET.

I could not find anything on a JDM L28ET. What about other models?

I will see it in person, and see what I can find. But, that will be a few days.

Japan loved that 2.0L, I know for most part US and Europe got better motors in the Z cars. Except for when the 260 got hit super hard by emissions.

JDM is a misused term thrown around for parts that people want to talk up.

If it truly is from Japan, it probably is an L20eT and the owner may be unaware of the smaller displacement.

I had a guy tell me he had an R200 LSD from a 280ZX turbo for sale. I drove over there to buy it right away and it ended up being an open diff. He just assumed all turbo Z-cars had LSD rearends in them... might as well be "JDM"

Hey Ratfink, i am in Phoenix and saw that ad, wondering same thing too, i just got back from japan and cant remember what i saw in the 280 there. but if u are looking to rebuild a motor, i got everything here but the head for a motor to be done if you are interested. when i bought the car the guy gave me all the spare parts he had save up and i plan on doing a RB or SR swap soon

Ratfink

Looking for something complete that I can swap in. I will build my ultimate L engine when I have a garage to do it.
But, thanks a ton for the offer. Who know's. If I end up in a house faster that I thought, I might go for it.
Right now, I am hurting at work, losing hours thanks to the drop in copper. I might have to wait till I can do anything fun at all. I'll just keep turning screws on the triple webers. haha

hoov100

apart from emissions, why? why the hell would consider putting that in any car? hell my grocery getter has atleast double that displacement.

Ratfink

You and me both. There is no real replacement for displacement. I hate to admit it sometimes. I draw the line at a sbc in a Z. No imagination. But stroked L28's are dead sexy. I imagine that RB20DET sounds sweet though.

hoov100

yeah, but i can make any motor sound good with a CAM though.

Ratfink

Even a Mazda 13B? haha

snwbrderphat540

rotary engines sound great! oh wait... i get the joke now.... nvm

Ratfink

Had to say it.

So I've heard the JDM VG30ET had more power though. Anyone know if that's true?

hoov100

from what i have read in the FSM's they have slightly bigger cams (same size as US 85T) and better tuning.

Did they get the VG SOHC turbo? I was thinking the JDM Z31 was RB20DET and the Z32 had the VG30DETT

snwbrderphat540

they also had the single turbo VG30DET. unless that was only a eurospec model. i think it was a jdm one though. no clue about the Z31 though.

lifegrddude

They did get the SOHC VGet. My friend had with a rusted out muffler and it sounded awful. Japan used the smaller motors mainly for road tax. The bigger the motor and the car, the more you pay annually.
