hello to all, I have a 2013 gt, I live in France, I would like to give a little more power, if I put an air intake from a model from 2015 to 2018, should I change the throttle???
and especially if it is worth it?
thanks a lot guys
Bonjour.
Before you start buying parts, set a budget and then consider the options of either keeping the engine NA (naturally aspirated) or adding a supercharger kit.
A supercharger kit with a custom tune can get you to 600+rwhp with just a weekend's work. You'll need to save close to $10k (€9k) but it'll be well worth it. Your next concern would be upgrading the transmission to handle over 60% more power.
Your other option is to enhance the engine with some simple bolt ons (cold air intake, '18-'22 intake manifold, long tube headers, your favourite axle-back mufflers, and a 93 US octane tune). This will cost you a lot less, and you can add the upgrades gradually, but the maximum you'll get is about 430rwhp (stock is about 375rwhp SAE). You will, however, be able to raise the rev limiter to 7500rpm so you can have 500rpm more fun, and you won't need to upgrade the transmission. If you have the MT82 manual, you could swap in a short throw shifter to improve the driving experience.
They have a LOT higher octane fuel in EU and France vs North America. If legal, Long tube header's and a tune would more than wake up that eng. Toss in the various options that beefcake mentions, and that would be as good as it gets for a NA eng.
Yeah, the lowest grade of fuel in Europe is 95 RON (91 US octane) though 97 and 98 RON are also widely available. It also has 10% ethanol.
AFAIK, European regulations require the cats to remain in place and there's a noise limit of 95dB. I'm not sure how strictly the noise limits are adhered to when a few Ferraris and Lambos are louder than that from the factory, but there you go. Therefore long tube headers with high flow cats shouldn't be a problem and it'll just come down to which mufflers you use.
