turbo engine or shortblock na thats been turbo'd

ok so i have a rx7 gxl that "was engine swapped"


heres my situation, ive had the car litterally 2 months. i bought it for 3500.. broken.. tranny went out, all kinds of **** went wrong..

ive had 2 previous owners contact me and say good luck and said nothing,

but today i got a person who emailed me and told me its a shortblock n/a that was turbo'd.... and he said he would flag my post if i didnt change it..

ive picked this engine APART.. and as far as i know the reactive turbo manifold that comes stock on the turbo 2 wont bolt onto a shortblock.. so im really thrown off by this guy..

whats a sure fire way to tell.. cause im 99.9999999% positive but that .000000001 percent is killing me and i really just wanna prove this guy wrong haa. also it has the mounts for the intercooler?? so wtf? idk..


any help for me deciding forsure... also its not on a standalone or anything its a stock n370 ecu. with a usdm wiring harness. on a "jdm engine"

remove the intake manifolds, look for the 5/6th-ports. If they are there, then it is a N/A block. If not, it is a turbo block.

Think you can also look and see if it's missing the place for the knock sensor above the spark plugs. If it's there then it could be na or turbo block. But if it's missing, it's an NA block. looking for the 5th/6th ports is a sure-fire way.

I notice you're in tacoma, i'm a bit north of you in sammamish. Do you have a link to your ad (I tired looking on craigslist). maybe we can see what this person thinks he saw that warranted his response.

ok so i just realized it IS a turbo because when i did my tranny rebuild i ordered turbo tranny sychros gears and shift collars and bearings and these arent universal through rx7's... not even s4 tii work on s5tii trannys.. in thus case its a turboii

also it has the right side mounts for the intercooler
it also has the knock sensor
it also doesnt have 6 ports


the guy emailed me back and said

"everything is direct bolt on from n/a to turbo i remember i put that intercooler on it"

then 5 minutes later i got a email from a previous owner that said

"just a heads up it was rebuilt/built by pineapple racing not atkins, they did the swap about 4 years ago."

lawllllllllll

Transmission doesn't say anything, since it can be swapped separately, although it does tend to lend credence to it being a complete TII swap.

huh? the turboii tranny wont bolt up to a n/a engine.. also the n/a tranny wont bolt up to the turboii engine..

thus being a turboii tranny it makes it a turboii engine. right?

Wrong.

Nope.

And I also highly doubt it has ceramic apex seals as shown in the ad.

You list 720CC primary injectors...I would assume you mean secondary.

What do you mean by a stock turbo with an open wastegate? Has the wastegate been modified to dump into the open air?

You list now power steering, but the car clearly has a power steering pump but with no belt. So that should say "The power steering is broken".

it doesnt have any issues
needs a bac valve (cold starts have to be manual revd and you have to use the anti flood to start it but fires up everytime-foot to the floor and turn it over)
tach sometimes cuts out but if you jiggle a wire it kicks on
check engine light is on and throws codes 11, 12, 13, 14, 17 which are emissions delete so it stays on, i can show you and pull up the service records and show you the wires that are undone and also the corresponding plugs.


I'd consider that an issue. The car is broken.

Your ad is misleading. I hope these are just errors of omission or lack of knowledge, because otherwise I'd say you are trying to deceive people.

Tonyreifel: The transmissions will bolt up just fine s4 or s5, n/a or turbo, but you need corresponding flywheels, starters, slave cylinders and clutches IIRC, as well as a driveshaft.

To the OP: that is most likely a turbo motor in there, and the guy telling you n/a to turbo is a straight bolt on upgrade is ignorant. If there's a knock sensor, no 6-ports, the oil neck has a bend, and theres a water line feeding off of the turbo side of one of the housings, its definitely a turbo motor.
