I'm starting to price up engine work for next year. Going to stg3 is obviously the cheapest option for a reliable 350-360, but from previous posts a genuine 400+ is in apparently in a different league(i haven't been in either yet). Ignoring the need for the uprate transmission as thats been covered, what is required from a pure engine point of view:

LC pistons
Head work - to what degree????
Cams?
Turbo (I take it my t3/4 will complain at this level)
RS500 style I/C (i have the std i/c and C/C with upgrade kit at the moment is the limit of this stg 3?)
Injectors
MAP sensor
Chip suitably mapped

New ancillaries such as oil and water pump, fuel pump, pressure reg.

Anything else? I'm assuming crank, rods etc will be OK.

Car already runs a breather.

Paul, its impossible to answer really as its totally budget dependant. However as a price guide complete 400+bhp engines start from around £5k upwards depending on just how wild a spec you want to go, and of course what donar parts/engine/turbo you have in the first place.

Paul Eggleton

OK thanks Karl, we'll chat about it more when I come up and see you in the next week or so.

Karl

No problem.

JRST

karl didnt you say you can achieve this 400bhp on a a t4 and std engine with some cams?

Karl

yes

My personal liking at the moment would be std bottom end, stage 1 ported head, mild cams, greys, t34 hybrid (or t4?) and the usual ancilliaries.

I think that would make a nice low lag 400bhp (ish) engine!

JRST

so would'nt that be the min engine spec required to achieve 400 bhp?

std head,
std comp,
must be great condition engine,
t4, (dont know about spec)
intercooler,
cams ,
grays

and shit loads of psi

have to say. from what i have seen on this board, and had a read of karls and stus work is rated and respected. For this conversion i would go only to them.

Avoid a T3/4, as it is on it's knees at 400bhp. I would try one of the new integral wastegated GT30s... .

Karl

Phil the engine you've listed won't make 400bhp.

JRST yes you could call that the minimum spec, BUT not everyone wants a T4, and is of course dependant upon you having a very low mile standard engine which is rare these days. If the engines being pulled apart anyway I always recommend going low comp.

Karl, it would if you used enough boost and revs on the T4

JC

Karl,
when can you fit us in for a live mapping and can you ive fuel economy on 8 greens safley off boost
4-5 to the gallon is a fucking joke
thanks jc

Karl

JC I can make it as good as a normal stage 3 803 car at cruise. That said any 8 inj T4 car is going to be thirsty on boost!

I my god Mike I am gonna save this post from you!!!

RANJ

mark gave me a very god price on 420 conversion on autronic, fully live mapped

Ginge !

ranj id hate to think what you call a good price based on the spec of your car

RANJ

that was expression when i looked at my bank accunt this morning

Ginge !

Engine 7.5k,2.5k Management, £750 for T3/4 400hp max or £1500 GT30 500hp, small turbo Inlet £150, this is the diff between 400 and 500hp.
