[centox8r]

Hi

I have a seicento 1108 mpi whats the best inlet manifold and tb setup for this engine is it the punto 75 inlet and tb if so is it a direct fit

stock inlet, and 1242 16v mk1 punto sporting TB.

P75 manifold will probably fit, but the fuel rails are wrong, as are the injectors, and the wiring for the TB, MAP, IAT etc

it's 42mm iirc, but not bolt for bolt - but its the easiest upgrade TB wise;

Oh yeah

Hi Rally i have used the search but if your not sure what your looking for then it can be of no use. As ive said im not to good with mechanics but am willing to learn but dont get much time to mess around, and as i need my car every day i cant have it off the road for to long

use the P75 TB and the aluminium stack under it and fit your 1108 top with injector inplace of the P75 top (which has no injector) this is a direct swap i did it to mine, it works a treat

an MPI doesnt have an injector above the TB, and has different electrics to the p75/cinq/sei spi generation.

sorry my fault mine has the P75 MPI engine in now and a bravo 1.6 16v with 47mm TB now i was thinking back 3 years (i'm in my forties now the mind plays funny tricks on you) it's the one with the nasty plastic manifold the 1.2 16v TB will be the easiest option, its the first one i fitted to my P75 engine before i went to the larger bravo 1.6 TB.

aye, i have that same TB (1.6 16v) on my 1.4 16v now
