S1 33gtst

so i got a s2 motor for a good price so what would i have to change?

im not sure if its just the motor loom?

any info would help thanks.

what is wrong with the s1 motor? if nothing, then honestly i wouldn't bother as they don't put out any difference in power. the turbo on the s2 has a nylon intake wheel so it will spool the tiniest bit earlier, but not enough to notice and they both have the ceramic exhaust wheel, and the turbos are the same size.

but to answer your question, there is very little you would have to change between the s1 and s2. the easiest way would be to use the s1 parts on the s2 motor for anything that is different. this will include the coils and ignitor (as i'm not sure if the s2 coilpack loom will simply plug into the s1 loom where the ignitor plugs into it), afm (different plug) and throttle body (the tps plug is different). there may be 1 or 2 other things, but they are the main things i'm aware of.

i spun the bottom end bearings in the s1.

that doesnt sound too bad then but i guess ill

have to change my pfc s1 and 2 are different?

No, Series 1 and Series 2 PFCs are the same. Try it and it will work!

yeah the ecu is the same. it is just the minor bits and pieces i mentioned. the main things are the same. anything that is different isn't too hard to change.

I wouldnt bother changing the afm, main thing is the coils and igniter, if the plug is different on the tps then just change the whole unit to the one on the S1 engine, i wouldnt bother trying to re wire plugs that could cause more damage than its worth.

[mad082]

the plug on the TPS is definately different. so it is easier to just change the throttle body than the TPS.

as for the afm, i am pretty sure that the plugs are different, or at least have different numbers of wires. could be wrong though, but it is a pretty simple job, so not hard to do.

and if he is getting just the motor it might not have the afm on it anyway

yeah only got intake side and head and block.

do you have any idea on a price it would

cost to replace bottem end bearings in my s1

would be a shame to throw away

always good to keep a spare.
