Can you drop a S5 T2 right into a 88 NA? I know there is wiring differences, but i mean, do you have to mod the mounting points, change externals,ect.... Trying to find out for a friend comtemplating a possible project. Thanks!

... Well i cant find one, so i need it covered again

 

the engine will bolt in nomral.bolt to trany normal and ehxuast,

are you droping just a s5 keg into an s4 or a whole long block?

on a long block wiring is drastically differnt,and s4 and s5 sensors and injectors are different, s5 radiators have the cap on them instead of filler neck, so if u have an s4 rad with no cap, then you wont have any cap at all! ask me how i know haha...

if you plan on using all s5 engine wiring harness ecu, afm, ect, then expect to do a fair amount of rewiring to get the body ahrness to hook up to the engine harness. you may even be missing a plug if you dont have the body harness at all for an s5.

another route cause im not sure which your planning on or were askinga bout is

s5 block s5 manifolds, use s4 injectors, s4 na wiring harness, rewire tps, run premix,extend bac wires, use all s4 t2 electronics, including ecu,afm, boost sensor, ect, remove emissions.

 

he's thinking about the long block, but he is unsure of how much will be different. Seems a bit, but nothing that cant be tackled if the rought is wanted!! Thanks for the info!!
