Good Day tuners,

Wanted to find out what's the easiest conversion engine and transmission wise for a b14.

Also what is needed for a qg15 engine and transmission conversion.?

Or a sr20 engine and transmission ?

Anyone could share some knowledge. Thanks

As the sr engine came as an original engine, you can actually use off the shelf mounts and axles to install and maintain regularly. I can speak about that as I did that conversion. Qg is newer and I am not sure what pieces and fabrication required for that installation.

Ok thanks. So is just the axles to change and same mounts from the b14 using back. Could the b14 hear shifter use back also?

No no, u have to use the mounts and axles specific to the b14 for the sr engine. Because this was a factory option the parts are off the shelf rather than having to fabricate brackets etc.

Shifter can also work, just remove the front from your tranny and replace to sr tranny

lets talk.

i did a qg swap in a b13 using a qg15 and transmission complete.
i used back the ga15 axles, mounts ect.

the engine mount on the belt side, has either 5 bolts or 4, the lower part of it needs to be chopped off and bolt up using either one or two less bolts.

had 3 if i can recall, shifter works, PS lines, ac compressor bolted back, did some mixing and matching but the original compressor worked, ps lines too.

the pain was the electrical, i called a guy to wire it, works fine to this day, horrible designed. with the 3 small jacks and the short ecu harness. if i had it my way i would of extended and shorten everything how it needs to be.

b14 easier.
qg is the way, super common and works well. i recommend the qg15 cable throttle without the egr. these are a bit simpler both electrical wise and troubleshooting wise

sr rell open to alot of mods, if you wanna do something good later on. u could go this way.

Ted, thanks man. End up checking out the engine mounts and stuff and realise it could work back. Axle and gear shifter can also work back from the b14. Rewiring is necessary. One thing I'm unsure of now, some men tell me the cross member might need changing in the b14 to accommodate the qg engine. This is what I'm unsure about now. Any knowledge on this?
