hi new member just wondering any more possible tuning help

[m30e30]

hi i have done a m30 conversion on my e30 and here the run down so far

samco hoses
ram air filter
super chip
fse boost valve
new cap and arm
full stainless steel pipe
modified manifold
100 shot of nos
dogleg gear box
spax adjustable psx kit
15" standard rims with michelin tyres


the only thing i no i want to go faster is im looking for a m3 diff any one got one cheap let me know can collect in uk
any further help on making it faster please help

ps santa pod raceway bimmer day coming up soon anyone going

close to 150 zoners i think , look on meets section sticky at top, turbo with NOS would be crazy, some guy on e30tech did a M10 with 1 bar boost and nitro and made about 350 from a 1.8, this was about 6 months ago and its still going

Lets see some pics

I didnt think super chips where that good What cam are you running?

i think the FSE boost valve are abit dodgy aswell i heard someone say, think it was ant

TURBOOO!!!!

Thats about it for reasonable cash, full blueprint of the engine would give you about 350-400 NA but would cost so much money to do.
Can get the same power with FI running about 12psi. Programable ECU of some description. Chips are great for easy power but still have to cater to a wide range of mechanical variables. ECU can be set to match your engine exactly.

And yeah pics please:)

i had a piper cam in it but had real bad issues with running problems i went with the superchip because he came to my work and fitted it i should have gone with the unichip i would have got 40 bhp gain as the super chip only gives 20
any idea of how to put up pics i have loads
as for turbo was thinking of it or a blower but i spent 5 grand on the engine rebuild and putting it in and thought about low compression pistons after if i get 6 numbers on sat i will

Megasquirt, then a turbo.

I may as well say it before Ant gets here

Very much doubt that to be honest.

A 'blueprint' is just bringing everything in the engine to the top of the manufacturer's spec, so it should really just make the standard figure, 218bhp in the case of the 3.5 M30 (I think?) and certainly absolutely nowhere near the 350-400bhp mark!

[Jos]

A rebuild would get you to 218bhp more or less using off the shelf stock items.

Blueprint is something different, it uses all the original specifications for the engine from design stage, exact sizes for everything with next to no tolerance. 350-400 would be obtainable if other stuff was done at the same time as the blueprinting, increased compression ratios, lightend crank, 5 angle cut valves, porting. A lot of power is lost simply in the compression stroke of an engine, the trueness of the bore and the ring tolerences and indeed the honing method all affect power generated per stroke. Also engines done this way also tend to be very well balanced so can rev higher (within limits of the valvesprings) and less power is lost shaking the engine.

'Blueprints' offered by engineering shops normally yield a 20-25% increase in power, and thats with no modification to compression or valves or ports. 350-400 might be a bit optimistic for most people, but it would be obtainable given enough money thrown at it, same as anything really.

Nowt wrong with Super chips, this is from my old E34, cam, head work and Super chip.

[Turbo-Brown]

Undoubtedly true, but changing things from the manufacturer's spec is not blue printing, and it really would take SO much work to get 100bhp/litre out of an M30, let alone 114bhp/litre!

Love the way people people quote power figures like '350-400 bhp' as though that last 50bhp is really easy to make once you've got up to 350bhp

[Jos]

would be nice to see how an engine built like that would run.. apparently it's night and day from stock engines, anyone have £20k laying around collecting dust? :p

And yeah ok, changing the spec isn't really blueprinting, but its normal practice in a blueprint rebuild for hi powered engines, so it all sorta gets clubbed together under the same term

and they 350-400 would depend on how good a job they did putting it all together, but I get what you are at

Nice torque curve Andy!

[e30_Turbo]

Turbo power!!

But I am biased!
