Hay guys iam looking at getting a 180sx very soon i went for a drive in one today and OMG it flew it had to have had a bigger turbo or at least boosted becuase it just flue when it hit boost?

the car i checked out was a 94 model but it had a red top engine can some one please tell me the big difference between the two engines black top and red top???

by the way the car was going for 16 k and had 55 thousand km on the clock seemed preety good started it up no smoke came out of the exhuast. reved it abit no smoke came out of exhuast.

drove it very nice smooth on boost. suspension was abit hard but ill get used to it. it was a gold colour =)

let me know guys +)

ohh by the way where are the damn turbos on these cars i couldnt see it hahahaha =)

There are two types of SR20DET's in the 180sx. First version is from 91-94 red top, second is from mid model update 94-98 black top. Don't confuse this black top with the one from the S14's & S15's as 180sx black tops don't have variable valve timing. If it has a flat cam cover then there is no variable valve timing.

As far as I know the only difference between the red and black top is the colour! Of course you have added benefits of getting a newer engine with the black top but thats about it.

I payed 13k for my mid model 180sx and am really happy with it, so for 16k you could find a very nice one, or you could save some more and get the 96-98 model!!

lol i will never get a straght answer hahah =)

all i know for sure is that they do have the same turbo the silvias dont have the same turbo?

and poele say that one got vvti other dont but then on the other hand alot of people said they exactly the same

and what you guys brough up about the ecu could be right=)

becuase they are two different series

well let me know guys

Thanks for your help

I have a blacktop SR20DET in my 180 and can tell you they definately don't have VVT. Only the S14 and S15 silvias/200sx have it. There is a different ECU in each of the three 180sx variants. Who knows why... could be better sensors like in the case of the different AFM. Turbo specs for red top and black top s13's are:

Compressor: T-25, 60 trim 56mm BCI-1 compressor.

Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.

Center Section: Journal bearings

Now it's time for you to buy one!

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
