Any Engine Differences Between Series 1 And 2 R33 Non Turbo Gts

[horze21]

hey guys

misses blew up her non turbo 1993 non turbo gts skyline

just wanted to know if there are engine differences between the engines in a series 1 and 2 non turbo

because I have bought one and don't wanna put in if I'm gonna run into problems

I found heaps of info regarding turbo engine but none on non turbo

thanx very much

Can't confirm, but I'd imagine the differences would be the same as the turbo motor's.

afaik s2 have different coilpacks and the ignitors built into the ECU. so grab an s2 ecu too

[horze21]

thanx for the reply guys..is there a way to tell wat series

the motor is..cause I bought one last week before I knew

about the diff series and wanna check wat series it is

if it is a series 2 engine ... does the series 2 ecu fit into a series 1 loom?

thx guys

sorry virgin boy, you're wrong. the s2 have the ignitor built into the coils, hence why the coils aren't interchangable. s1 ecu will work in a s2 and vice versa.

the engines themselves are the same, it's just some of the electronics have different plugs. easiest thing to do is just swap in the engine and use the existing coils, TPS and AFM. will make life much easier than changing the loom.

thanx very much for that info... is there a way of checkin if the motor is a series 1 or 2 ?

[skylinesandman]

check wat coils and afm its got if its got em they should be

a three slot plug i got a series 1.5 but the motor is series 2 motor

oh yeh thats right

always get those two mixed up

[horze21]

hey guys ..motor swap has been dude fired her up last night working good..havnt driven it yet as radiator not in yet.....but I followed what mad082 said and it started first shot

the motor is practically a

series

1

now correct...why is the reason they changed all this..for

performance or reliability issues. also ...r33 n/a and turbo models fan shroud the same??

thanx very much every1 for the help...especially mad082

fan shroud should be the same.

as for why they changed things, sould be one of many things. could've been due to cost cutting, new technology (resulting in price reductions or supposed better reliability, or just cosmetic changes), or a few other reasons.

They changed them because individual internal ignitors are better and they updated the loom plugs to a better design. series 1 uses the same type used in old 300zx and those plugs suck.
