What to do and what to do first? That is the qestion? I have currently hardly any engine mods and want to start off gradually, but stuck what to buy first. I have purchased some forged pistons in readiness for things to come. I obviously will buy some conrods to go with the new pistons. I`m thinking of buying a new uprated fuel pump (Walbro 255) Would this be worth buying yet or waiting until I have an intercooler fitted and new Turbo? It seems to me I might be better biding my time and buying everything and fitting them all at once, then remap. I am impatient though and want to do something. What do you think guys?

Already installed
Apexi induction kit
Decat pipe
Kakimoto race exhaust.

Well if you've already done your suspension and brakes, I'd fit a Walbro and sort out the gauge of the wire thats driving the fuel pump.

Got a good air filter with plenty of cold air around it? What about a de-cat?

gets pretty expensive when u start looking at rebuilding/upgrading internals very quickly. personally i would go for a good standalone (boost solenoid controlled by ECU or boost controller) to start off with. mapping is where its at

had a friend of mine that ran 402 bhp standard internal R33 with no problems whatsoever with PFC, boost controller, intake, exhaust, steel interal'd turbo, decat etc. Ran very strong for about 2 years before he just up and decided to rebuild it with forged internals, and a GT4035 and a tubular manifold.

It was tuned by Tuning Japanese in London btw. dont know their rep but his car did run reliable and strong. that i know.

De-cat already fitted. Susupension has lowered Trial springs but not uprated shocks as far as I`m aware. There is a rear strut brace in the boot. Brakes will obviously need attention too.

If the internals can cope, I can get turbo`s for cheap so quite easily swap the standard turbo for a 400bhp plus. Once I do that I`ll have to add a whole lot of other bits to cope with the extra power.

Always tune the chassis before the engine, you'll find that you're going through the corners that much quicker that you're faster on the straights. :-D

Have seen (just) over 500hp from the standard bottom end.

Gary at APT mapped one a while back with the following spec and it made 501hp:

Greddy plenum
Greddy intercooler
Tomei Poncams
Trust 1.8mm head gasket
Power FC
6x 740cc Nismo injectors
Greddy TD06-25G turbo
300ZX afm
Apexi air filter
Greddy radiator
Apex oil cooler kit
Denso plugs
Nismo fuel pump
Apexi AVCR
OS Giken twin plate clutch

depends on what he wants the car for. think hes just after more power at the moment.

more power first then sort the handling out, don`t want to do a mixture of both.

So the wiring has to be changed for the pump?
