Hi Guys

 

I own a UK spec 300ZX TT manual. In the last 2 months i have purchased and in the middle of fitting the following :-

 

Greddy Profec B Boost Controller

Apexi BOV's

Greddy FAT Turbo Timer

Greddy side Intercoolers

Smithy Under Drive Pulley + Belts

Hard Radiator Pipes

Hard Turbo Pipes

Koyo Radiator

New water Thermostat

New Water Pump

Greddy Radiator Cap

Carbon Fan Cover

Oil Filter

Greddy Oil Adapter

Gauges + Sensors

New Oil Pressure Switch

3 POD Pillar + Gauges

Mocal Oil Cooler

Blits SUS Induction System

De-Cat Pipes

New Oxygen Sensors

RPS Max Clutch

RPS Flywheel

RPS Pin

S.S. line

Short Shifter

Energy Systems Poly Suspension Kit

GetGreddy ECU

Iridium Spark Plugs

Grounding Kits

 

Now looking to future. Next engine mod will be new turbos. Planning on keeping standard turbos for a bit as they have only done 2000 miles.

 

My question is, i am thinking of uprating to JWT Sport 530 Ball Bearing Turbos w/ Downpipes + a set of 555 injectors. will i need to replace engine internals? The engine is new and only done 2000 miles? Or what PSI could i run before i need to fit new pistons etc?

 

What sort of power should i expect to get with what i have fiited so far on 14 psi. Both at fly and rwhp?

 

What power would i be looking at with new turbos & injectors. Looking for big-ish power if pos with turbo whistle.

 

Thankyou for any help

 

Kevin :bow:

if your upping the boost youl need forged pistons or you will make that engine a grenade.

 

Greddy do decent upgrade kits, but i wouldnt do it if you have stock internals.

christ you spent shit loads i take it your not married

thats one impressive list!

Yes, if you want the best out of your tubs

360 ish fly 300ish wheels

not a question of power with stock internals, more of a question of how long the internals last, candle that burns twice as bright lasts half as long :nelson:

I have standard tubs and internals. Only engine mods are JWT Chip, boost controler (set to 15.5psi) RPS clutch, Blitz filter, de-cat. I got 325bhp at the rear wheels (400 at flywheel) on Thore's rolling road.

You should theoretically achieve a higher bhp than me because you have more engine mods like lightened flywheel etc.

Yes m8 I'm serious. 324.6bhp at the rear wheel to be precise. The torque is the best part 342.6ftlb at the rear wheels!

Attached is the rolling road print off.
