Before I even ask I DID use the search function and found nothing. I know I will get flammed for this and I am sorry if this was already asked, im new cut me some slack please.

I just Bought a 2003 G35 coupe 6MT, My goal by the end of the year is to get a greddy TT on it. But before I do I want to get the most HP outa my car before I go FI. Which mods do you guys recomment I get. I knew a few are intake, exhaust, cams, header but what else can i get to increase hp before I go FI. I do not really care about handling since I wont go any track racing on this just a few drag racing. I have 15k left. Body work isnt really that important. I am going to put a kenstyle kis with jdm badges on it, and lower the g around 1.5".

Any help what so ever would be great appreciated.

 

Yup! someone is going to flame you for this.

Ill be nice. So all you can do is get bolt-ons. And in order to get the most HP out of them, you will need some sort of EMS and tune. Other than that.. just get the TT and call it a day.

 

Thanks I appreciate it.

 

Get the TT and bolt ons that go with it. Intake will be a waste of money since it will be taken out for an intercooler. I believe the NA bolt ons do not work well with FI anyway since its designed to increase compression where as FI builds want lower compression. Someone correct me if I am wrong.

 

You want a TT but are considering headers? Interesting.

IMHO, if you are willing to spend the money it takes to buy/intall headers, cams, intake etc. etc. etc.. I'd put that down on a built short block instead.

 

Well Im really only looking for 450 rwhp I heard I dont really need to have a fully build engine for that. But if it helps the longevity of the engine that I believe thats the smart thing to do. Also Im a complete noob when it comes to moding an engine and will most likely have a professional shop do all the work.

 

Anytime you boost an engine with a 10.3:1 compression ratio N/A, you'll want to change a few things. You can push something like 8psi on the stock motor and be OK, but longevity does come into play. I agree with Jeff, go with a built shortblock. Z1 sells a stage 2 for something like $3,400 after the core refund for your current engine. Rebuild engine with new rods, pistons, etc. The Z1 block has a compression ratio of 8.8:1 which means you can boost it more, but it also means that at 8psi, you'll be at a much more stable compression.

Last thing you want to do is spend around $10K on your TT build and then throw a rod.

 

Well If i upgrade the block would i also need to upgrade the heads? And if i do upgrade these parts I could run a higher boost for more power also correct? I guess I have to look into a new flywheel and clutch also ><

 

You can use stock heads, but the main thing you want to upgrade is the rods and pistons. You might as well get cams while you're doing rods and pistons. Not doing cams seems like a waste to me.

 

You have been such great help. Do you happen to know a lin for noobs that kinda helps on what mods to get and what not? Like a newb guide haha

 

I say you get some low compression pistons and Eagle Rods(connecting rods), clutch and flywheel combo.
