[GSR_RICHO]

Hi all now that the GSR is back up and running time to start tinkering again. It still is pretty much all standard and looking at making it more performance orientated.

Firstly Mechanical, should i keep the TDO4 or upgrade to a larger turbo? if so would the TD05 bolt straight on or would I need to change manifolds and such?.

The Injectors and fuel pump would have to be upped I am gathering also to either EVO or VR4 ones?

What kind of boost would this run safely without doing to much damage to motor?

In regards to FMIC i am trying to find a nice bolt on kit im not one for bling but i would like a decent sized front mount. Can anyone point me in the right direction as to a good kit for the 4g93t.

Sorry for long post but lastly anyone know a decent supplier for and EVO 3 kit. Mainly front bar so as to be able to fit FMIC?

Thank all for and replies?


If there are any other sort of upgrades you guys and girls would like to add that could be a good start please feel free to post.


Regards

Depends whether you want a brand new one or if you're happy to go 2nd hand. For example, you could pick up a VR4 Intercooler from the forum or a wreckers for not too much cash.

PWR do some nice looking FMIC's: http://www.pwr.com.a...=products/s=is/

What kind of boost would this run safely without doing to much damage to motor?

I would have thought that in stock form you wouldn't want to run higher than 13-14 psi to be safe, but other 4G63 owners on here may advise differently.

should i keep the TDO4 or upgrade to a larger turbo?

The GSR turbo is pretty small. That might be an area where you might be better off upgrading. Other guys on here can hopefully advise what changes you'd need to make in order to fit a bigger turbo. Big 16G would be a popular choice?

However, if your exhaust system is still stock, I'd fit a 2.5 / 3 " Manderel bent exhaust sytem & Hi-flow Cat before playing around with turbos.

The most popular upgrades I've seen commonly mentioned are:

1) 510 Evo III Injectors
2) 055 MAF
3) Evo III ECU

Ok, to answer the questions:

TD04 will be fine for response. Changing to a TD05 will require manifold and exhaust changes (new ones of both). I'm not absolutely sure on the details, 3zercrowd can walk you through it (or you can search, there's threads on it)

Injectors and Fuel pump are fine for what the stock ECU will let you do.

You can't wind it past 15psi without getting boost cut. Damage occurs about 22psi give or take.

FMIC, get an Evo 1-3 secondhand unit and either use the piping that comes with it, or get a plazaman piping kit. Anything made for an e1-3 will fit a cc gsr.

E3 stuff is best sourced genuine and 2ndhand then fitted and cleaned up. You will need bonnet, front guards, front bar, rear bar, side skirts and rear pods for the complete set.

I think for the td05 you need to make the exhaust manifold exit hole bigger so it flows Into the bigger exhaust housing properly
Also mods to the oil lines etc as they are bigger on a td05

To properly answer. Using a combination of the above.
A search would find you all the answers!

Firstly, Id assume if you still have a TD04, that you have a 4g93T.
I've done both a TD05 14b VR4 turbo, and Evo 16g upgrade.
I found the 14b an awesome street turbo, instant response, quick spool, good fun.
The 16g gives me great top end power but takes a little bit longer to spool up on the 93T.
Both of these turbo's are direct bolt ons. Your choice will depend on what performance you want.
Manifolds are the Same. The 93T manifold simply needs to be ported a little bit to accomodate for the larger turbo housing, which is quite easily done.
Best upgrades for these things are Evo bolt ons.
For a start the Evo Injectors, MAF and fuel pump are crucial, along with an Evo ECU, or chipping your GSR ECU to match.
While doing this you'd want to make sure you have a decent sized exhaust, you may also need an oil filter relocation kit.
The Evo throttle body too is a good upgrade, but not necessary.
On a 93T, its recommended not to go above 15psi, otherwise things may go pop, mostly due to their weak rods.
In terms of Intecoolers, the Evo cooler is fine, and will provide enough flow for up to 240+kw.
Also a direct bolt on.
For the body kit, if you want genuine, good luck finding one because they're quite hard to find, but do sometimes pop up. For fibreglass, they do pop up every now and then on the forums, or ebay even. Otherwise try carmate.com.

or you could do the old 14B rear/16G front cover combo and get the best of both worlds (or somewhere in between)

I was reading thru a post on evocoupe.net, there forums are probably more informative in the way of a 4G93T.. not many 4G93Ts here and most of them dont really know too much other then what they read..

jump onto www.evocoupe.net and have a quick search.. heaps of 4G93T info there.

Both of these are the same bolt pattern yes, but are not direct bolt on as you will need to modify the turbo manifold exhaust housing, match ported to suit the TD05H otherwise your wasting your time with such an upgrade, its like blowing into a straw... Also in regards to the oil/water lines, they all have to be modified to suit the Td05. The intercooler lines also need to be modified, your exhaust will also need to be slightly modified as the td04 and td05h have different kinks in the dump pipe.

Manifolds are the Same. The 93T manifold simply needs to be ported a little bit to accomodate for the larger turbo housing, which is quite easily done.

IMHO from experience you will not need to relocate your oil filter. Your better off running a stock dump pipe then a custom made one because unless your making over 220hp you will not notice a think, trust me i know this from experience.

The Evo throttle body too is a good upgrade, but not necessary.

If your going to upgrade the throttle body to a 60mm evo one, please remember you will need to port the factory 4G93T intake manifold as it has roughly a 45-50mm opening, so same again as the turbo its like blowing into a straw.. if anything you will lose power cos urs blowing 60 into 45-50mm..

On a 93T, its recommended not to go above 15psi, otherwise things may go pop, mostly due to their weak rods.

Obviously if you want more info.. feel free to message me, i have alot of hands on experience with these motors and can tell you most of the ins and outs.

Just reading thru your posts.. if your car is standard this is the template i would follow in modifications.

1. Turbo upgrade
2. Build exhaust around turbo upgrade
3. Intercooler upgrade
4. Boost upgrade to 13psi
5. Clutch (do it then or do it when it starts to slip your choice.)

All the above should be good enough for around 130-140kw ATW

Way to insult insult every forum member who owns a GSR!

No offence to you i said 'most', most people do take their cars to a workshop that do the upgrades for them.

There arent many DIY's and yes i can understand sometimes they dont have time to do the work themselves..

However there is ALOT different about an EVO - Aspec GSR - Jspec GSR that if you havent fked with them you wouldnt know...

Jon

[boostboy76]

No offence taken. Should have put a emoticon after that!

I do my own maintenance on my GSR, but have only just started working with a 4G93T

You're right, there are a lot of differences.

[JSTYLE]

as posted on evocoupe.net

http://www.evocoupe.....php?f=2&t=5571

from my experience with 4G93T aus and jap spec can very most of it is very minor but can bite you in the ass if you didnt know.

Heads are different, the thermostat setup is different and has a different flange.
Rocker cover is different (dif bolts for the garnish)
Garnish is different.

I also believe the turbos are different, the other day i tried to swap rear housing from an aspec TD04 to a jspec TD04 and it didnt fit, the rear housings had different numbers stamped.
So possibly the turbos might be abit different.

Jon

That is only just a GSR engine!!! Imagine how much more is different!

Jon

[boostboy76]

Even though the engines are different, the basic priciples are the same.

All engines are giant pumps, so it pays to get them "breathing" as efficiently as possible on the intake and exhaust sides first, before you go looking for gains elsewhere.

Not that I'm claiming to have anywhere near the knowledge or experience of most of the guys on the forum!

hows it coming along?
pretty enjoyable motors to work with that arent too much of a hassel.. as long as ur abit mechanically minded they are fairly easy to understand and if you ever get stuck shoot us a pm.. ive had those motors built to 230kw and stuff...

FYI, it may be strange but im a baker hehehe i work with dough for a living!!! lolz

just as long as u dont start stripping the motor you cant run into trouble hehehhehehehhehehe

My biggest problem ATM is that I have a JDM GSR, but at some point someone has butchered the factory climate control and spliced in the Aus Spec manual Air-Con system!!

I've already blown two air-con buttons because of electrical shorts in the dodged up wiring, turned out the air con wiring wasn't even fused by whoever f*cked it up when it was blowing switches - lucky I didn't shock myself!

The Air-Con guy I've taken it to is having all sorts of dramas trying to fix it.

Can't even trace the wiring properly, as half of it in the engine bay has been disconnected and then the stuff that is connected is completely different to what's under the dash!?

Think I need an electronics degree and a mechanical qualification!

Sounds like a nightmare! I wish sometimes i was abit more electronic saavy too but oh wells..

I think the climate control runs into the top of the passengers side dash.. and not into the engine bay? Have you looked at getting an evo dash loom to replace it? might be a better fix in the long run and i wouldnt be suprised if it all plugged in like it should!
