I know threads similear to this have been covered a thousand times but anyway... here we go again :lol:

I am looking into fitting a 16v lump into my RSi but theres just a few things i am not 100% sure on!

Can i use my RSi driveshafts?

Is the RSi radioator ok to use?

Will i need to get a 16v exhaust mani heat shield?

Will the ecu just be plug an play, or will there be imobiliser issues?

And any advice on anything ive missed out would be great!

Cheers guys

I am 99% sure i can, but ill ask anyway...

Can i fit my RSi gearbox on a 16v? and which flywheel would be best to use RSi or 16v?

Also what kind of ratios would i be getting using an RSi box on a 16v with a standard limiter? :wink:

Yes, Rsi driveshafts, will need 16v rad unless you can make the pipework fit.

Get a phase 1 loom and ECU and it will be plug and play to an extent, you'll need to modify the car loom to co-ordinate with the 16v engine loom (easiest thing to do would be to fit a 16v dash loom and fuseboard etc.

Yes the box should fit

16v flywheel

Ratios would just be normal RSi ratios. No idea what speeds it will do at 7200 RPM etc tho

I will have the 16v engine loom if that helps?

I thought it was just a case of swapping the engine loom over?

also my car already has the oil pressure sensors as standard (PH3's have them already)

When you say it will be plug and play to an extent what does that mean lol :roll:

He means a phase 1 ECU has no immobiliser so nothing to worry about wiring wise.

Right sorry for sounding a little dense but if i put the 16v engine in, keeping my PH3 RSi main loom and using a 16v engine loom...

I could just plug a ph1 16v ECU and jobs a good en? :roll:

i will have a 16v rad soon for sale, nearly new..........

Should you need one

Yes thats right - you only need to swap the engine looms.

Out of interest, why you swapping for a 16v?

There isn't much of a performance gain to be had over the RSI to warrant doing it IMO.

Better off waiting for a willy lump or sticking a 2ltr 8v BE on.

Theres a nice 150BHP 16v engine for sale that is local to me (evouk's)

and i just fancied a change all the cars ive ever had have been 8 valve

not in all cases, the dash looms vary as stan says in this thread

you "might be able to just plug the 16v engine loom into the RSi car loom and it'll work, then again it might not work and might need a few wires swapping over.

That thread was about a 1.4 main loom wheras the RSI engine is the same series as a 16v.

I'd put money on it working first time.

That would be nice, but knowing my luck it wouldnt work at all haha!

What gearbox would you reccomend using a 16v box or the rsi?

The rsi has shorter ratios so this means when crusing at 70mph it would be revving higher than a 16v gearbox?
