yes its a chipped ecu that makes it fully programmable via a laptop and allows to run any injector, different AFM's etc. Comes with tuning software ecu. www.nistune.com (http://www.nistune.com)

just wondering if a turbo cam would be better to use in the hi comp setup? like help stop pinging or any added stress to the head... only reason i ask is because i have one laying around. but dont know if its worth using or not?

can anyone give some beter information on changing a s1 rb30 to a turbo . has anyone drillled &taped the holes or found another way of doing it ??

exactly where will i find the water and oil line bolts on the s2 na block? does anyone have a decent photo of them? thanks

trentZ do a search, look at turbo conversion posts. theres some good posts just do a search.

Hi Guys, Do you need the Turbo Wiring Loom to do the conversion or can you stick with the n/a loom? Also would an 87 model calais be series 1 or series 2? After June is series 2 and before june is series 1? cheers

If your wondering about the motor, look at the passengers side of it and see if the block has the spots for the oil and water lines already there. Wiring loom i'll leave for someone else. Knock sensor would at least be missing from the NA, but lots say it doesn't matter.

does a vl n/a turbo 5 speed manual computer work in a non turbo auto vl?

vlcalais! i don't think it would work

This is really helpful. Thanks. Some original photos have not been recovered yet.

sorry for thread bump but i had this pic from my 30det build which i thought might be useful as i saw few ppl asking about series 1 and series 2 engines. these are the oil and water lines on a series 2 rb30: also last i checked im pretty sure all 89+ Vls were series 2 and some 87's. also all r31's have series 2 rb30s

that will help heaps, cheers

correct me if im wrong witch i have a feeling i am but to do a dodgy conversion couldnt u get away with just manifold turbo cross over ? .. as long as u dont run above 6psi it would work wouldnt it? also when you have the dump on the turbo will it line up to where the cat is on a NA?

dump and front pipe will line up with the cat on an N/A, they are the same.. You can run the cross over pipe, but you will still need turbo injectors and ECU to prevent pinging and internal damage to engine.

even on low boost?

Yes! otherwise why would Nissan produce them with more fuel? PLUS N/A motors have more compression than the turbo motors, even more reason to need more fuel!

Has anyone found a trusty head gasket size for this conversion? To drop comp a bit?? Looking at doing this in the next month But with a canary yellow with black bars and trims. Has anyone ever strengthend the MF5 with a completely rebuilt box? Really want to avoid getting a 33 box or having to do the MX conversion. Have the box thats going into it apart for a complete rebuild.. Some original photos have not been recovered yet.

is there a thread on how to do the converson from scrach?
