[Dragon18]

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 =)

i think the black top one has varable inlet timing.

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!!

do you think its true that there is nothing different about them?

the two engines??

=)

I am after a 94 onwards 180sx because of the interior. That one you saw sounds great, where was the car at ?

what have other payed for around 94 model 180sx's and what mods did they have for the price ?

[Guest Nismo_Freak]

The only difference is the type of ECU used in the cars. Other than that they are both the exact same motor.

I'm not sure if they are exactly the same motor cause a mate of mine had to swap his AFM and the later model one had an extra pin.

[deesh]

doesnt the later model have a different turbo? im pretty sure i read something about the later model having BB turbo or something, try a search, its here somewhere.

[Dragon18]

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!
