What Can Be Achieved With Modified Stock Parts ?

[gts-4 dreamer]

For example can the stock boost controller be modfied to hold increased boost levels?

How adjustable is the stock exhuast cam gear on a r33 25t, ie is it practicable use @ time of tune. does it have enough adjustment in it to be of use?

Can the stock fuel pressure regulator be adjusted to a higher pressure requirement if required ?

What parts can I increase in effectiveness with some modification for those of us who wish to increase output without the mamoth pricetag involved ? Ofcoarse some need to be out and out replaced depending on what your aims are ofcoarse I'm just wondering where we can re-use the stock parts

some of us also have mortgages and dont quite earn enough to indulge in thier hobby / passion as much as they like.

Im thinking what have we got that is needlessly upgraded when we simply dont requrie it or there is an alternate method that is cheaper and just as effective. No dodgy hand grenade setups or something likely to fail miserably.

Ideas?

1) not sure

2) no, you need to spend money to make it adjustable, even then from what ive seen there is no gain anyhow

3) no

Unfortunately performance costs money, and hardly anything is free unless your a fabricator and use your own time/skills to make stuff.

The basic stuff is around 4-5k or there abouts.

Its just the usual parts that require money.

Exhaust

I/C upgrade of some kind (R34 SMIC or FMIC)

Bleed valve

S-AFC/ECU & a tune

Clutch

I wouldnt call mods "needless", its more a return on invesment.

You get good returns for the first few thousand, then you need to spend more and more as it goes up.

Especially your first 3 points... they are possibly the cheapest items to purchase to begin with

true, they just happen to be where I am at on my path to a better performing car. The idea of the thread was there were some places maybe I could improve the OEM or re-use the oem that I may not have thought about, my listings were just ideas.

the stock boost controller would be good as making the second stage boost slightly higher and saving on an adjustable ebc.. which i wouldnt call cheap. but yea there are alternatives.

got the FMIC installed an a 3" cat back.

got a 3" wide body cat (honey comb style) not yet installed (finding gaskets to fit is a mission so far, prollly pick up from an exhuast place).

need a front + dump, thinking the btmbl just incase i go for my full hp target or change compressor, but finding someone who's selling this second hand seems hard since no one seems to be giving them up and instead is keeping them.

getting a 20psi vac/boost guage and the $22 ball n spring type bleeder of ebay (the one fromt the 8 page long thread here) next week also a decent pannel filter.

need a fuel pump and planning on an intank replacement as Im not going over 250rwkw at any point.

Then the decisions on the big money, management, compressor, injectors.

which way I go on management will determine the last 2 and whether or not i go for 220-230 or the 250.

u can get a VL fuel pressure regulator and find a socket the same size as the top where the vac fitting is and compress it slightly in a vice, doing this will bump the pressure up a bit

You can adjust the crank angle sensor to retard or advance the exhaust cam... Fairly dodgy though, no way of telling how many degrees it has been moved.

Besides that, you could try the high boost solenoid trick found in the DIY section, water injection, up the boost to 14psi, fuel cut defender, split dump pipe, hi-flow cat, cold air intake. All fairly effective and produce noticeable difference in power. Or just add N20.

There is the $22 boost controller and the autospeed fuel and ignition computers, plenty of things you can do with spending too much.

Locally made zorst heaps cheaper than jap ones

Local oil coolers and radiators the same

Bendix ultimate pads and RDA or DBA rotors are cheap.

You can modify the cam gear if you really need to, it only needs a few degrees to make the difference - but it is very hard to set or adjsut accurately.

GTR stuff comes cheap as well, gtr fuel pump fits straight in
