Default vovlo 460 1.8i , perfomance

Hi there people I have a 1993 460 with the 1.8i B18U
I'm experimenting with the possible addition of power,

I was wondering if anyone knew if I can switch the SPI unit for the MPI unit for more power?

Also I have been wondering if anyone has suggestions for adding some BHP ?

eagerly awaiting comments

I always found the B18U went really well and was very economical . If you want to do something with a bit more power then there is the turbo , more complex and can be taken to 155 bhp which will get to 60 mph in 8 secs or less . A good compromise is the Early B18E a really nice engine with twin throttles and a stainless bunch of bananas exhaust manifold delivering 115 bhp ...This engine wasn't around for long probably due to the cost of the tuning bits ...
Then There is Renault and their vast range of engines and bolt on parts ...

Ah ok , i have got my eye out.
They did a 1.8 mpi though didn't they , mine is spi.
So if I take the Ecu ,inlet and injector rail from the mpi it should work ?
What do you think ?

You would have e to change the wiring loom over too. If you are going to all that work you migration as well go for a decent amount to of power.

I haven't heard ofa 400 series fitted with one but what about a Renault F7P or F7r or F4R?

The F7P swap has been done. You could even fit a formula Renault engine!

The 2.0 litre ones are quick.
Many of the turbos lost their engines for fitting in Renaults, the Volvo version of the engine being stronger, I understand.

I thought all 1.8 engines were single point, the others were multipoint, with some 1.7s being carb'd or turbo'd.

The 2.0 is a good compromise, not as complex as the Turbo but goes very well and can crack over 40mpg on a run.
