Engine Mod Advise Needed

[rowska]

hello i have recently bought a 1993 r33 gts.

What are the best engine mods to do give me more power?.(Without a entire engine overhall)

[Eug]

you don't really buy a GTS for power. however if you do want a little bit more there are a number of things;

-nitrous

-turbo conversion

-rb30 conversion (engine transplant though)

-intake

-exhaust

-cams

-timing

-ecu/piggyback

a search on any of those keywords should yield more details.

if you're interested there's a group buy currently in the works for extractors.

we don't really need more threads for 'how to get more power', there is a plethora of information on the forum with extensive details and results. give them a go.

when i get time i shoud write up a sticky thread collating all the data.

theres plenty of threads on this even a couple i had heheh

but for my N/A with out goin into too many high tech mods

air/pod filter

extractors

exhaust

with a good setup it should give you raise in roughly 20-25kw if your lucky

this is what im planning on getting done then rims and maybe bodykit later on

Dont waste your money, take it from a guy who owns the same car. Spend your money on a nice car entertainment system. Trust me you would rather have a sound system than the 20kw because you wont notice the power i guarentee you that.

Save your money until you get your full license and get a GT-R.

yeah it all depends how much $$$ you got to spend...i did headunit, amp, sub n speakers first..at the end of the day if you tihnk about it not point wasting thousands on power only to go the speed limit fair enough exhaust cai n that but wouldnt recommend much more unless your serious about your car and its power output...just my opinion though. gl

a 20kw increase where? top end, mid range, low rpm??? the kilowatt is one thing, driveability is another.

you'll be saving a long time to own a GTR

correct. unless you intend on fully utilizing the mods for (bragging rights not included) there's no point.

even some of the 300HP GTSTs are being wasted cruising from carpark to carpark...

..guh..

Can we please Sticky a unversal "How do I get more power?" and "What do I need for my exhaust?" thread!?!?

In all honesty.. there isnt much you can do to get decent power out of an RB25DE without taking out the block..

As said before.. pretty basic plan is

Intake

New cams

Ajustable cam gears

Port and polish

Shave/deck the block

headers

Zorst

ECU and re-tune..

Work your way through that.. and you should be sweet..

I suppose if all done well you could get 160kw.. perhaps?

You could always go a 3L bottom end.. Could have you pushing 220kw.. perhaps..

With NA engines.. dont aim for a "larger power figure" thats all bolocs.. aim on making your engine more resposive with a larger powerband..

Hey man, im sortah in a simillar boat to you, i been doin alot of reading and i think ive worked out the best way to get the most out of my car without goin to far overboard... i have a 96 s2 r33 gtst (turbo version) so this is my rough action plan (if urs is non turbo just ignore the turbo components). First thing i did was car alarm, tinted windows, car stereo, and 19" deep dish x factor rims... then i did the increase boost mod u see on these forums to bypass the dual stage boost and set it to a constant 7/8psi... and these r my plans for whats commin next... (in no real order)

96 Nissan Skyline R33 Series 2 GTS25T

Future Modifications:

- Exhuast - full 3" split dump and quality 3" high flow cat keepin size all the way to the back, mandrel bent with high flow muffler

- Intake - Apexi POD Filter with cold air box and cold air intake (this will allow u to hear turbo without need for BOV)

- New Springs to lower the vehichle

- R34 GTT Side Mounted Intercooler

- Turbosmart dual stage boost controller OR R32 Wastegate Actuator to increase turbo boost pressure to 10/11psi

- Turbo timer

- Neons

- Apexi Power FC ECU upgrade

- Dyno Tune
