Idea What are the five best upgrades for a 147GTA?

Hi,

Have had my 147GTA for a month now (and enjoyed every minute of it!!) and spent a lot of time looking through the forums on this site. What I cant find is a single thread listing the top modifications for a standard GTA.
Which are the most cost effective?
Which give the best results? etc. etc.
I'm sure you all have your favourites, how about sharing them?

Re: What are the five best upgrades for a 147GTA?

oldboy, have a look through the GTA threads for suspension upgrades, exhausts and breaks. Lots of people have posted experiences thereon.

If you really want to splash out, Autodelta seems to be a pretty good tuning house.

Re: What are the five best upgrades for a 147GTA?

1) Coil Over suspension. The single best thing you can do for your car.
IMHO The adjustable Autodelta sportline coilover kit is awesome.

2) Braided hoses, upgraded pads only needed for the 330mm discs if you drive like lunatic or do track days.

3) Limited slip diff if you are reaching the limits of your cars handling

With all of the above your car will be the way it really should have been when it left the factory, and will have 100% more control than standard, which obviously was pretty good already.

Cheers,
TB

Wide-boy,

That exhaust looks great. What make is it? Also over 300bhp from the engine, is it still reliable and easy to drive around town?

Thanks everyone for your responses, it looks like i need to start saving!!

mmm I liking that exhaust, next on my shopping list I think.

Oldboy - welcome nice GTA you have there. Get some coilovers as TB says they are the single best mod you can do, as the std GTA suspension is prone to bottoming out. Mine is now 15-20 mm lower with the coilovers and doesn't bottom out 1/2 as much now, plus the handling is great.

Next a remap and maybe a CDA intake, and then an exhaust... good luck

Re: What are the five best upgrades for a 147GTA?

If your after being able to handle what its already got then first should be the brakes and/or preferably a decent set of springs/dampers.
Most 'standard' 250bhp gta's go faster point to point when the drivers are able to actually drive them - adding another x bhp doesnt make any real difference so maybe a driver training lesson is the best investment of all....

IMO the air intake system isnt worth anything more than a few bhp at most. A decent air filter to replace the paper one is most of the effect that an 'induction kit' gives (which is basically just a flasher version of whats already there, ie pipework and the standard stuff is alredy as large an internal diameter as the intake....)

If your after power - the best 'bang for buck' is definately a re-map.
Id tend to steer clear of the supersprint stuff - its hideously expensive and not a great improvement on the standard kit IMO (manifolds in particular), if you want a free'er flowing exhaust to help your remap then a pair of high flow cats and a new rear silencer generally does the trick - id stay away from 4 exit exhausts too - unfortunatley the gta exhaust sytem goes from the 2 manifolds into one pipe - so splitting it again later on i just a waste of money as it doesnt make any extar power over a single exit rear box.

A one off rolling road remap will of course be best as it tunes the ECU to your specific car, but the cost over going to say Autodelta for one of theirs isnt really worth the extra 10-15bhp you 'may' get out IMO.

so id say:
1. brakes
2. suspension
3. drivertraining
4. better air filter and reworked exhaust
5. remap.

if youve still got any cash left then get an LSD... of course if you have all the cash upfron then just get either a supercharger conversion or go the whole hog for AD's 3.7 GTAM set up

Re: What are the five best upgrades for a 147GTA?

re 1; brakes if you have 330mm already wots the need
2;suspension yes kw is the best i have tested AD system is not a bad copy of it
3;air filter the std is not bad most foam type replacment are just thinner layers so air flow is better but need to be replaced or cleaned , the right exhaust system or back box linked with remap

Re: What are the five best upgrades for a 147GTA?

Mods so far to my 147 GTA:

Aragosta E Sports Suspension
ARC Anti Roll Kit
Unicorse Titanium Tower Bar
Bollente Rear Parallel Link
Bollente Front Lower Bar
Ferado GS 2500 Brake Pads
Goodrich Braided Brakelines
Delphi 5.1 Brake Fluid
Potenza RE-01R Tires
Asso Sports Intake Pipe
K&N Sports Filter
Hot Inazma Hyper Voltage & Ground System
Phillips Blue Vision (High Beam/Fogs)
Redpoint Fiberglass Engine Undercover

I would say the most transforming change I have made was the Aragosta adjustable coilover kit, followed by the anti-roll kit. As great as the 147 GTA is, it is extremely topheavy which you feel clearly under hard cornering. Roll is quite pronounced as well which the ARC kit eliminated almost completely, even at it's loosest setting. I think the braided hoses and pads were an excellent investment for me as well since I tend to drive hard on long curvy mountain roads and found a good amount of fade with the OEM pads and hoses after hard braking into about 20-30 turns. The undercover is a nice cheap way to increase your ground clearance, and the additional strut bars were also quite inexpensive as well....

1. because even though they are an improvement on the 305's they arent the best in the world... esp if you plan to up the power the car is making. Upgraded pads and possibly disks are a good idea along with braided hoses.

2. the ad set up are KW's - theyre not a copy, theyre re-branded with ad's own springs

Re: What are the five best upgrades for a 147GTA?

Thanks Guys,

Some great ideas. Where is the best / cheapest place to start purchasing the bits (when I have saved up that is)?

Also, is the improved handling from a damper/spring upgrade through better body control or through lowering the body. I am a bit reluctant to lower the car further than standard due to the number of speed humps in the area.

Regards

Rob

Better suited damping/spring combination.
The KW's and the Bilsteins come with adjustable platforms so ride height is up to you.

Exactly. The Aragosta E setup is the same. Mine is lowered about 1 and a half inches all the way around, but with the stiffer setup I never scratch the lip or worry about speed bumps anymore.

That said I have changed the standard (plastic) undercover to a fiberglass one ( to UK OldSchool) by Redpoint both to increase my road clearance as well as to make space for my Bollente Front Lower Bar .
