turboing a campus
« on: 18:40, Fri 05 November 2010 »
Has anyone done this?
I dont mean taking the engine out and putting a c1j in or converting the c3j to a c1j, but turbo the engine itself.

I ask because Its a fuel injection system.
It has a lambda probe so i can detect if its rich or lean

Im not looking to make 120hp, but do you think a standard engine would be able to withstand say 6 psi?

The campus engine is too high compression, also oil pump isn;t up to job nor is the timing chain tensioner. The valves are smaller and rocker shaft isn't suported as much as a gt one, also cam is diffferent. The throttle body won't fuel for turbo applicaton either

To be hoonest to turbo the engine correctly your be left with a block and crank and thats it from the original engine, everything else will have to be changed to cope with a turbo

Surely thats only if i want the same type of engine.
If its still running under 100hp would it really need sorting out.

Im just asking really, i dont know what i want to do yet wether its build an engine out of the car or volvo engine it or f7p it, but this is an option im thinking about, it sounds the cheapest for now

No you need to change all the bits to make it work correctly, the parts in the campus lum are designed to be used as a small NA lump, not a turbo lump.
To be honest there is no real point in turboing the campus engine, its not really up to the job and putting boost through it is only going to weaken it more plus you won't get it ti fuel right with the original single point injection.

I'd personaly fit C1J or one of the other 2 engines you mention

I like the idea of fitting a c1j as its easy to build. But you know i had nothing but problems with it. The volvo route sounds the most appealing to me.

I know you had few issues with the old engine but they are good engines, that cars still going strong with 17psi just been painted too.

Volvo is a good lump too, very simple to do and to tweek.

Ive heard of that being done, as you dont need to map anything to get more power, just adjust the carb like you do on the c1j

Its possible, the compression will need to be lowered, an exhaust manifold made and a inlet manifold will need to be modded to adapt a carb onto it. Few other bits will need doing too like swaping the AEI unit, oil feed and return etc.

Prima Racing use to do it years ago as a conversion, i been looking for one of these engines for while as keen on looking into whats in it and seeing what it could do, getting bored of the C1J.

I personally wouldn'ty go to them mate, they woukd charge the earth for something thats fairly simple to do yourself. From what i saw of a mates conversion would never do the power they claimed

Completely different design head mate, only simiar is they both have 8 valves.

The C1J is a pushrod engine so cam lives in the block, GTX lump is overhead cam so cam lives in the head and runs a cambelt
