Engine Upgrade

[loser1]

iv had an r33 gtst for about 6mnts and now am wanting to modify my engine. the only modifications are intercooler and pod filter that i noe of. i hav $10000 to spend and was wondering if anyone had any advice on modifcations to get the most power from my engine. i hav in mind to put in a computer, new fuel pump and injectors. also will be purchasing a new turbokit with a bigger high mount turbo. are these mods wise? Also thinkin bout converting the rb25 to a rb30 block is there ne great advantage to this or is it just alot of hassel for only a minimal advantage? Ne advice would be much appreciated.

It comes down to what you want to do with the car.

Personally, i want a car with good response at the expense of top end (even though i have fluked a good balance) as my car is predominantly street driven.

With that in mind, I dont think you can go past a garrett 3071IW (or 52 trim 3076 IW if you want more then 270rwkw) on the stock manifold, with dump and lines and intake pipe installed should be under 3k. You're at the limit of your stock internals already.

Id get hks 256/264 cams for about 1200 delivered, add 300 installed.

z32 afm and pfc (if you can find one) 2k installed and tuned.

5 inch metal cat and cheapy exhaust and front pipe from someone like just jap say 1200 installed.

555 nismo injectors, say 1k installed if you get your own off nengun or perfect run and have them installed with the rest of the gear.

The remaining 1k or so on swaybars and upgraded springs and shocks.

There's a lot more suspension and driveline stuff you will need to do later on to get all the power down but your out of cash for now

If it was my money, I would sell the GTST, and buy a GTR.

Get a car with a better starting base.

I concur once again

I've added in some rough prices into the quote above...

It works out to around $8,600 not including labour which will makeup the $1,400 once it all in/fitted etc etc.

However a crucial point, i'd also add a clutch to the list $1,200... so total will probably be closer to 11k give or take

The car will be much faster with the money spent on important areas like suspension/braking.

It will also be much more fun to drive than something with just outright power and absolutely no way to use it.

I see little point in spending just 10k on the motor alone for big turbos/manifolds/3ltr bottom end as its totally out of the price range. Its closer to around 20k by the time you do it all if you want the handling with it.

You could "just" spend the 10k on all the power, make 300rwkw, but the car next to you with 250rwkw will give you an absolute hiding anytime, anywhere.

Being it will have a good lot of parts that make a fast car, not just a banger motor.

Power does not automatically equal a fast car, it an overall package. And for the street, 250rwkw is about as much as you'll need

So loser1, take the advice or not, thats just my personal opinion after being around for a few years

I agree. Too much talk of 300rwkw and not enough of a decent car thats going to go the distnace and be able to dirve well.

eg decent suspension upgrade will cost you 3k installed. Bilstiens, spings, swaybars, bushes etc plus install.

Clutch as mentioned...for 250 or so there are plently of options. about 1-3 k installed depending on ur option.

5k of those alone which doesn't make power...just allows ur car to use what power u just made.

thanx guys for ur input i appreciate it it helps but i already hav sway bars, brand new adjustable coil overs, aftermart 3" straight through exhaust so handling and suspension is not an issue this is about power gain. I will make any adjustments later if neccessary. The turbo has already been rebuilt with a larger compressor wheel. I hav ova 200rwkw im jus lookin for the 300 mark or over. and the clutch will be changes cause its stuffed.
