you'll most likely be nicking bits off a G60 anyway.

If you change your mind I've got a G60 Rallye ECU you can have, not for free obviously  :evil:

If you want my opinion, (which you may not :laugh: ) I'd say you'd be 100 times better off getting a g60 lump. You mightn't like this because you already have a working engine and it seems more expensive. Even if you get the thing running you don't know whether it'll last 50k miles or 500, and you won't have to worry about lowering compression/upgrading fuel systems etc. You'll pay a premium for the g60 engine no doubt, and you might think retro-fitting stuff will work out cheaper, but I'd be surprised if it did - it's always the little things that end up costing the most.

If you decide to go this route, then you're budgeting make sure to work out what it'll cost you down to every last washer - and then multiply it by 1.5 and you'll be pretty close - that's what I did with the car in my sig and it still worked out more expensive! :grin:

Can you seriously justify buying a turbo, manifold, downpipe, oil feed/drain, coolant feed/drain only to run 2/3lbs boost?

Just buy a G60 lump, digi1 ecu and loom and go from there. If you don't want to buy the g60 engine then just fit a spacer plate to lower the compression a little and fit g60 manangement to do fuel and spark for you. You will need a chip for the ecu which can be bought cheaply from Germany or the states.

ive got to join in with the masses. with the expense you're going to go to just to run a t/b or s/c, you may aswell get a lump that is s/c or t/b'ed anyway. forced induction on a standard old engine is just asking for trouble, its designed to run on a vacuum, not to be pressurised.

after you've bought all the bits, it will cost the same amount as a normal fi engine anyway, to see about 20bhp gain, if that.

buy a proper lump and dont be silly.

im NOT gonna buy all that! whats 2/3lbs boost gonna be, 10-15ish bhp? bet i can get it for less than 30 quid! might not be a lot compared to what a G60 can do but 10bhp here an there will do for me!

im not in a position to spend big at the mo, believe me if i blow this engine i WILL look for something to replace it with but untill then i just want a few cheap mods to see this one thru an play with!

Can I ask how you're planning on getting this 2 or 3 punds of boost into your engine without fitting a turbo or supercharger, which it seems you aren't going to?
