Its clear (for me) that you are inexperienced in modifying, whereas some of the reponses (Jonlem, Steve, Corsakid, Phillip and me! lol) are built from experience and have made some mistakes along the way - so we know a bit more...

To see over 260 you need solid lifters, a pukka manifold and exhaust, some decent injectors (probably 8, not 4), plus all the other bits mentioned and about £10-13k.

I have a pretty well specced XE and it has cost me a few quid - it just gets my goat when people say "pfff, you only have XX bhp?? My mate has 275 bhp with a race head"

No one is slagging you off, if you post that you will get 275 with these mods etc, and its not right - then people will disagree.

FACT.

Plus points for how many for your friends you could mention in one post :thumb:
well If you read what I said I wasnt expecting to get said power from I currently have im not thick. thats what my ultimate goal

Dont really mean much.


Anyway, engine bits etc look well :)

Cheers mate.

Cat Cams Rods £670
86.5mm Accralite flat tops £500
Blydenstein head £800
Piper double springs £250
Arrow solid lifters and shims £300
QED 450 camshafts £400+
Jenvey 48mm tapered throttle bodies and MBE 967 ECU £2000
Steel flywheel £250
AP clutch £450
Simpson manifold and system £1500

That was a 230hp specced engine, made 224 with iffy cam timing and yes I have the graphs, that adds upto over 7k and thats not included a LOT of parts it had like pulleys, machining, gaskets, oil pump etc...

---

Well either graphs count on this website or not lol and there is no mention of a SCCR box doesnt he know what he is doing :p

The costing i put up was a estimate not a actual final figure. but lets talk numbers then:

DTH bodies £2000
dta + loom £1000
pistons £550
Rods £300
Forged steel crank £835
Double valve springs £200
Cams £400
GM lifters £200
TTV Flywheel £200
Clutch £400
Manifold £300
Exhaust £300
potential head £2000
Plus bearings, machining, ancilieries, ARP's etc so because My build will be nearer £8k By right pub figures this means my enigne is better than your mates cause it costs more :thumb:

Am on my bb and that last bit made me piss my. Self and drop the phone lol as we have said to you all watch this space

This is turning into a comedy thread, why would you plan to spend 2k on a head then run it on hydraulics! But spend another grand on a crank! And you want it to be reliable I take it, ( well I would for 8k ) but the fact is it's not going to be! Not unless you spec all the components accordingly, people are trying to offer you advice, how you take that advice is up to you weather you see it as criticism or an attack against you! It's not noone wants to see you throw 8 grand into something for it to end in a component failure and all end in a swarf infested oily mess on a drag strip or a track!

Yawn

Hydraulic lifters eh, ok mate, you clearly know best.

It has f**k all to do with my mates costing more, its the fact it was built with that power in mind and thats what it had to cost.

What exhaust manifold are you using as there are probably only 2 off the shelf manifolds that are known to work on high output xe's, the others have to be custom and you take your chances using those.

You have back tracked more and more in the last few pages, one minute its going to be 260+hp when its built, now its just your goal eventually ? its not going to make much power at all if you can't rev it, you do understand that don't you lol

Whilst you have some nice parts sitting there and its not yet assembled I would advise you consider changing the spec a little to solid lifters, solid profile camshafts and maybe take note about the issues with xe's breathing so look into a Tony Law or BTB manifold as you will need it to achieve the numbers your looking at.

It might benefit you to stop being a pi55taker and actually take some advice from people who DO know whats needed to make those sort of numbers from the chosen engine rather than think were all internet experts and don't know what were talking about, especially Steve when he has been there many many times.

I know some people are giving advice but then it turns into a slagging match just because something is slightly different to how I have been told it needs to be. I understand that at that level tolerences are so close its unbelivable to even think of the consequenses ( I have twice) all im getting at its not construction advice or critism it reads like its a piss take :thumb:

So if you understand tolerances are so tight WHY are you planning to run it on hydraulics and ****y cams?
