Which Turbo

[Bull-Dawg]

Hi all Newbie to this site but I am told this is where to come for all the answers...I have a R33 which is Automatic (yeah I know nans car and all that but I have been driving for 17 years and manuals get boring after a while) I have installed a 3" Stainless mandrel exhaust and a Intercooler not a monster one but big enough, I have wound the boost upto 12psi. I ran a 14.8 without the intercooler and the boost at 10psi, now I want to run a low 13 sec or a high 12 sec if possible but I still want it driveable on the street. Has anyone any suggestions for a turbo (bolt on preferrable) that while get me the time but not the hassel on the street. I reckon the car would do a Low 14 sec now its just the launching I have to get done pat.

:headspin:

Ta for any help

Might want to think about suspension... And new turbo I'm guessing a new ECU so you can tune it up good.. Should do well.

before changing the turbo you should consider the following parts as you'll certainly be mxing them out and they will need to be upgraded, generally the turbo is the last thing to change as all the stock components wont be able to keep up

injectors

- stock injectors are 370cc will max out at about 200rwkw

fuel pump

- stock pump will max out around 200rwkw

airflow meter

- stock afm rb25 will max its 5volts around 210rwkw

engine management

- youll have big draw backs with stock ecu, aftermarket will give best benfit to all the upgraded components, allow tuning and adjustment and also support upgraded components

3" dump and front pipe and hiflow cat

- if you have the stock front and dump and cat they are restrictive and should be changed. 3" turbo back is a good setup, you said 3" exhaust, not sure what you have changd etc

tyres

- what tyres are u using? youll need some fairly good tyres for grip

automatic gearbox upgrade

- the stocker gearbox (auto one) will be placed under heavy load above about 200rwkw. im not sure exactly what level it is considered bad for it. you shoud look at a transcooler for it defenitely. do a search on auto transcooler a lot of guys over 200rwkw fit them

cold air intake

- wether a pod with a heatsheild and cold air feed or hiflow panel filters in the airbox. just make sure it gets cold air and the air is forced directly to it.

suspension

- stock suspension is probably okay but youll benefit from some better springs, pineapples, damper kit or some form of suspension work

having said all that you can certainly do a cheaper version or an expensive version

here's probably two "okay" options

option 1

220rwkw

turbo

- rb25 hiflowed or hks 2530

injectors

- s15 480cc injectors

fuel pump

- skyline gtr fuel pump

airflow meter

- z32 air flow meter

engine management

- remapped stock ecu or apexi safc or greddy emanage. you wont be able to change to a full aftermarket ecu such as apexi powerfc cos it wont support the automatic gearbox. most ecu's wont support it. so best would be remapped ecu with limits taken off and changed fuel maps. youll need a remap to run bigger injectors. apexi safc will support z32 airflow meter. stock ecu by itself wont support z32 airflow meter.

3" dump and front pipe and hiflow cat

- you may already have these, if not then get your local exhaust shop to do it or buy one from the forums under for sale section

tyres

- 245's or 255s on the rear

automatic gearbox upgrade

- transcooler

cold air intake

- pod with cold air setup

suspension

- pineapple kit to prevent axle tramp

option 2

260rwkw

turbo

- hks gt-rs or garrett gt28rs

injectors

- 550cc injectors

fuel pump

- skyline gtr fuel pump

airflow meter

- z32 air flow meter

engine management

- full aftermarket engine management. have a search on some ecu options. i know powerfc and wolf wont support auto skyline. when we or i say wont suport as in it wont speak to the gearbox during gear changes, so the gearbox just gets mistreated and excess load placed on it. the ecu doesnt have automatic shift logic built it and wont know how to handle the auto gearbox. if you still insist on aftermarket ecu then change the gearbox. one that isnt electronic then you can choose whatever ecu you like. transbreak or a modded vl turbo box, something that is mechanical will work great.

3" dump and front pipe and hiflow cat

- a must have

tyres

- 255s on the rear

automatic gearbox upgrade

- transcooler and stage 1 shift kit. speak to vl turbo guys (calaisturbo.com.au) and have a look around for upgraded automatic ideas/suggestions

- plently of vl turbos use auto boxes and get massive power figures

cold air intake

- pod with cold air setup

suspension

- pineapple kit to prevent axle tramp

LoL big ass List dude^. mate since u already got a 3" exhaust best thing to do is hiflow ur turbo wat is on ur r33 now. wit that turn up the boost to 14-18psi and u will get into the low or mid 13sec's depends how good of a driver u are.
