I think you\'ll find that flywheel figure mate.

What\'s the calculation for wheels to flywheel?

So what can you expect to put out of your stock twins assuming you run them at standard boost and upgrade the fuelling/rad/injectors/intake/intercooler etc..?? (At wheels that is)!

315rwbhp approx

Not bad at all!

Although whats the ballpark cost to get to that stage (if anyone would care to share their outgoings)!

Then once I\'d blown up my stock twins after craving yet more power (bound to happen) - would I just need to splash out for a single turbo, clutch upgrade and new pants if I was going for a T04Z / T88?

approx

induction £150
ECU 650
Exhaust £250
Downpipe £150
CAT replacement £130
Mapping £400
intercooler £800
Fueling - no idea

plus labour


obviously all depends on what you get and where you get it

[mr_tim]

Assuming you already have a Power FC or similar...
rad - £350
fuel pump - £150
injectors £250 ish?? - depends on size and if you need a new fuel rail or not
intake/intercooler - Apexi £1150

Plus labour and mapping

Roughly speaking - there will no doubt be bits and bobs to add to this

[Initial-D]

Yep got a Power FC, and full straight thru with decat.

All looked quite promising until I got to the intercooler! Hmm a bit costly!

How many injectors would I need.. looking at 1,000 secondarys I think. Would this need a new rail?

Seems best to go the upgrade twins, then big turbo. As the cost can be spread over a longer period..

1000 secondarys are a bit pointless if u intend running a single tubby in the future. do the deed and a get a meaty fuel system now e.g. new sec fuel rail, 1600s, 040 (may be 044) pump, swirl pot,  FPR, aeroquip etc.

1000-1300s will fit stock rail but are expensive as they are stockers sent to US, bored and sent back - I think Pip sells them for 175+vat each.

That\'s not at standard boost though. You would have to crank the boost up to achieve that figure. Aalso the turbos themselves are not a weak point so you hoping to blow them would take you some time. The weak point is the operation of the turbos acuators, solenoids, check valves vacuum pipe etc etc.

Looks like I may have to get on the phone and discuss my budget and long term goals with a rotary guru!

I love sound of singles and a nice noisy wastegate! Plus some super big flames when u let off the gas!

Maybe I should save up and just buy a track car from Japan and keep the one I have now as my lady puller!!

I seem to remember John\'s car is running 14 PSI and is also street ported.

On the matter of costs, don\'t forget to add garage bills if you\'re not/can\'t do it yourself.

What\'s considered to be THE or one of the best intake kits? I like the GruppeM CF one but it\'s not practical when upgrading, APEXi or HKS? Taking into account that I\'d fabricate a heat shield if required.

Cheers

14!! That\'s quite high for the stockers, Hmmm.. thinking cap time.

May have to go for a rummage around the net for prices on the parts, I could do the intake and rad/intercooler, then leave the fuel side to the pros;)

Cheers

John runs 14psi and a pretty conservative map.

14psi for the stock twins is not that big a deal I dont think. Much more is though. Ant poo\'d his twins running 16psi+ very quickly...

The apexi intake kit is one of the better reputed intakes; power and filtration are both excellent.
