DIY supercharging - Inlet manifold question?

[Flipatron]

I've a Rover 1.8 K-series which I'm thinking of supercharging. I've limited space and would probably end up re-fabricating the VVC inlet manifold in order to fit the supercharger onto the engine. My question is, how much of the plenum chamber has to remain in order for the injection system to function correctly?

Any reason for your idea?

You can get quite a lot of power out of that engine by being N/A, and I wouldn't have thought it was the ideal base for a supercharger conversion, while I don't hold the view they blow headgaskets every five minutes like most, there are better and stronger bases. Is it a kit car or production car?

Elise S2. There is probably a N/A route but I'm just weighing up the options ATM. I've also considered the MG ZT turbo unit for my car but they seem quite rare.

The reason for the supercharger is simplicity and cost, oh and it's different!

Doesnt Turbo Technics offer a Rotrex kit for these cars ?

What sort of blower are you using ? For some, there should be no reason to butcher the intake manifold at all.

[Flipatron]

I'm thinking of using a Mini Cooper S blower, size is about right and I think it would suit the 1.8. There's a spare pully available to run the blower it's just the location and how to feed the air in.

[stevieturbo]

Remotely mount it, fit an intercooler, and blow into the std manifold.

Thanks, sounds to easy!

Without knowing the details of the K-series injection system, it is most likely you will be exceeding the capabilities of the standard system once you have fitted the blower - the standard injectors and pump will simply not be able to keep up with the fuel demand. Furthermore, the standard ECM will probably not be able to cope with so much positive pressure from the blower, meaning your fueling is probably way off which will end in tears.

I would be prepared for the minimum of a standalone ECM, completely upgraded fuel system and some wiring challenges.

Look for others who have boosted the same engine and find out exactly what is needed.

as steve said, basically replicate the MINI setup but using the K-Series. bigger injectors may be needed.

PS be intresting to see a trubo kit for the K-Series eilise.

Unless you actually fancy the project you'd probably be better off selling hte car and get a Toyota engined one instead - plenty of power and it won't break as often!

I've done a s/c conversion on my 106GTi and the results are very good but it's a lot of work and expense if you want to get it right.

how about replacing the 1.8 K-Series with the VW 1.8T?? they can amke BAGS of power, are relativly cheap and plenty of them about...

Cheers
