New scoob 04; I dont disagree with any of the advice you and some others have given here. It is all sensble and wll get saxx to around the figure of 360 bhp he has decided on for some reason. His prblem here is sorting ouut the good advie from the bad.
Also as you point out, 320 or similar will be easy to get and far cheaper as there is no need for change of turbo or injectors and less chance of gearbox or clutch probs.
For 360 bhp. Questionable advice is;
tdo5 16g. Usually struggle by340 or 350. So td05 not a 360 option.
vf23s will and do run over 33o bhp so that IS a330 option
Plain bad advice.
440cc injectors.
tubular headers.
You cannot run a 98 uk at360bhp without sorting charge temp anda fmic is the easiest answer. Itcan do 360 on tmic at360 but reliability is risked.
Sorry if my last post did not show where I was coming from.

Ok so to try get it in one place then,
to get around 360bhp,
fuel pump and regulator
550cc injectors
A good Induction kit (dry type)
TD05 18G or 20G
Sti 8 Topmount (with undertray) or a Front mount
ported oem headders with a decat (or sport cat) 2.5" turbo back
Remap EcuTek, Simtec, Apexi Pfc or like.
That little lot would get you to that point. but could also get you near 400 depending on turbo choice.

do you mean that for 320bhp 440's are a bad idea? (think ns04 was getting at for 360 you 'll need bigger injectors when he said you need 550's)

I'd say almost spot on. so many different opinions
I'd say ditch the fuel regulator and go with 650 injectors.

Power Junkie, I agree with you except that without an sti8 scoop you will still have charge temperature issuesand as that puts£100 more on cost and there is a lot of work to ke fit sti 8 tmic right so i wood go for a Hybrid tube and fin from Harvey. cheaper, quicker, better.
What i mean is exactly as I posted if you read it again. 440 injectrs do not do 360 bhp reliably, even if they nearly get there @ VERY high fuel pressure fully maxed out and you sad nothing about needing fpr.
IF existting fpr is god condition and the target is 33obhp you would get there on new walbro pump but be near100% idc. but coulddo 315 ok and be safe IF fpris ok and save cost of fpr.£125 plus fittings and guage.
Best to aim for max 85% idc and if you fit a fpr then reverse the fuel flow.

P1dazza, you just need a new undertray to cover the topmount, Its not that hard to fit the intercooler really, have a look at Carl Davey's project. I have done it on mine too and running 400bhp and no problems with temp at all. but the main thing is it has less lag than a frontmount and i could get the APS induction fitted without pipes in the way.
its just another way to get there really.

if you have to buy 550's and a regulator to up the pressure. Why not just go with 650's?
Gives some headroom for further upgrades.
I had a choice of a regulator or the 650's. choose the injectors for future proof
Its also a personal thing, But i didnt want to run upped fuel pressure on standard hoses. so had i'd gone for the regulator i probably would of ended up spending on braided hoses etc.

The Sti8 scoop looks a bit odd on a classic but fine on a newage....... in my opinion

seems a bit pointless tbh, you can max out the block/pistons and rods on the 550's, then after that its rebuild time and then you'll need the bigger injectors, but can't see someone wanting a rebuild within a year of spending that much money, at which point i'd prefer to have new flow tested injectors anyway, fresh for the new engine

I'm going back to TMIC, but I'm a bit worried about the turbo (20g) toasting the intercooler from underneath via radiation heat etc... I've fitted a blanket to mine (and wrapped DP) but I might build some kind of additional heat shield too that would stop the majority of the radiation heat. It should be possible to fit a sheet of aluminium there somewhere without messing up the air space behind the IC too badly, I think.

I have heat wrapped the turbine end of the turbo as well as the downpipe. Some worry that this shortens the life of the turbo 
I sell new and refurbished turbos with 12 months warranty whether wrapped or not, would I recommend this if I thought it was an issue !

I have a smaller STi7 type scoop too. If the temps are controlled this summer I'll consider going back to OE classic!
