Info on a cam.

I have already looked into mapping etc. using a fast road can will give gains without a remap. You will get even more gains when you get it remapped.

If I dropped in a 1.6 8v engine, with cams, ITB's, a decent map and my 4-2-1 manifold and exhaust I could be pushing for 130bhp. It obviously isn't as much as a '6 but my car is also 200kgs lighter then a '6.

I understand what people are saying and yes i have looked at buying a '6/1.8 but I don't want to. It's something different that I will do over time to spread cost etc.

Im not saying don't do it, just that in my opinion it is an unwise avenue to explore, due to the extortionate cost of tuning an n/a engine (believe me, I've spent a LOT of time agonising over what path I want to go down with my '6; and n/a just makes it less driveable every day and costs a friggin FORTUNE!!!)

So roughtly costing your intended build out:

Cams: £300 + fitting & Timing (& excluding vernier pulley you'll need to set it up right)
ITBs: ~£1,500 (I'm assuming it'll be slightly less if you can get parts on the cheap etc. as it's £1900+ on spoox website incluing management! http://www.spoox.co.uk/catalog/product_i...26a614d0cd
4-2-1 manifold, £370; http://www.spoox.co.uk/catalog/product_i...26a614d0cd

Plus decent mapping: £4-500.

And that's ignoring the fact you wont have a base-map to run it up to your mapper on... and those mods will cause significant differences in breathing which will affect the afr. and after spending that money, you wont want to be running it lean all the way to the mappers....

You'd see far better gains for the money spent in turbo'ing Jim, there are quite a few of those kicking about; it's not the obvious choice in a 306 either so its not a mainstream choice, and you'll have more room to mount a turbo in the bay than in a spaxo/106 too

I think there's a 1.1 turbo 106 quiksilver if you wanted to work out what's involved.

Not sure what the upper boost limit is on the 1.4 TU engine before you need to go forged, but I'm sure you can run low-boost and get some pretty epic gains. Thinking about it, the 8v head may even work better in a turbo application too...


And DUM just NO.

1.8s shit themselves everytime you modify the inlet/exhaust on em without going standalone, because it cant regulate the fuel and runs rich and fucks em.

you CAN re-use the sensors, but again as I've already said, without adjusting the fuelling parameters to take into account the increase in air, you wont neccessarily get any more power, and you will long-term run rich/lean at different points in the rev range and will f*ck the engine.
