What Are The Key Ingredients For An R33?

[QRI05E]

Ok guys, my 165rw/kw is getting bit too plain now.. Needing more shove in the back acceleration My R33 is virtually stock as a rock except for the 3" split dump and 3" exhaust and K&N panel filter... Now my next mods are:

FMIC

Aftermarket ECU + Boost Controller

Injectors

Fuel Pump

My questions is, what specs of each Mod should I go for in order to accommodate future engine re-build or larger turbo... in other words what FMIC size would be good enough for a larger or hi-flowed turbo and 15+ psi? What size injectors and fuel pump would be sufficient for 250+rw/kw applications? etc...

Another thing, what mods are recommended to increase bottom end power? up until 4500 RPM when the VCT kicks in, there isn’t much power on bottom end as shown on my dyno graph...

Thanks heaps guys! Any info will be greatly appreciated!!!

Kind Regards,

Well R33's come out of the factory with a lead+iron composite monocoque, so acceleration is a problem .

ECU+EBC will help bring the full boost on earlier. For 250kw+ you will need to look at injectors, fuel pump (Bosch 040/044) and a bigger turbo.

[rev210]

the first question to ask is what do you want to do with the car?

from there you may have an idea about what sort of accelleration, handling and braking you want to aim for in a compromise with driving in traffic.

Power is only one aspect.

[teazn_r33]

i dont belive that you will need injectors for 250 as i have 300 rwkw with stock ones but i suggest you get a huge mofo pump like a 044 and a bigger fuel pressure reg a ecu and bigger turbo fmic ebc and bobs your uncle if he can tune lol

[Boof]

Ummm nope, injectors and pump in R33's are meant to be at max around the 200rwkw from what i beleive....

he isnt talking about a standard pump he is talking about having a huge pump and fuel reg to achieve the absolute max out of standard injectors. Whether you could achieve 300rwkw im not agreeing though you certainly achieve more then 200rwkw with various other fuel system modifications.

umm yes you can maybe you should try it as i have i have a bosch 044 motorsport pump surge tank malpassi rise n rate fuel pressure reg and i get more than enough fuel for my car

I am at 228rwkw at the moment and my injectors are at 90%.

[paulr33]

pick a power figure and how much money you have then aim for that, dont pick one and then go ill maybe change it later on cos you may buy the wrong parts. my advice go for a drive in a 200rwkw skyline and then decide. its at least 6k of parts involved to get 200rwkw. my next step for your car would be ecu and fmic + boost controller.

[teazn_r33]

where do you ppl shop 6k ???

r33

fmic

ebc

filter and full zorbie

199.8rwkw

[paulr33]

yeah but it wont drive no where near as nice and safe as a properly tuned and setup car. ie ecu, fuel pump, split dump exhaust. and i would also doubt that power without a piggyback

fmic 1200

exhust 1200

ecu 1000

boost controller 300

tyres 500

suspension 1000

cold air intake 350

thats using rough pricing, which is reasonable also

I am at 228rwkw at the moment and my injectors are at 90%.

You must have a problem as theres a lot of ppl running 400rwhp with stock GTR injectors.

[R33S2]

A good tune is the best way to use all these mods properly, dont baulk at the most important stage.

[teazn_r33]

sorry i wasnt talking about suspension i was just talking about motor mods

yes i belive he might have something wrong with those injectors at 90% with my power i have at the moment im overfueling the car and thats with over 300rwkw

[BezerkR32]

This is a package i do regularly for customers.

1) Walbro 500hp intank pump $310.........no need for surge tank or reg etc.

2) Hi flow turbo (bush bearing) $1350.......uses all factory plumbing & ducting

3) Apexi Power FC $950..........plug in, no installation cost.

4) eBoost1 on special for $550.........note that car will see 15psi with hiflow turbo. so if thats enough, you wont have to worry about boost controller & sometimes can get away without computer. If yor looking to run anymore boost then ECU and EBC are necessary.

5) Good quality intercooler & pipework, either PWR or Hyperflow core with long pipe being before core and not after like you see on most cheap kits. $1000

6) Good quality split dump & cat, whic you already have.

This package is extremely streetable, cheap to install and retains stock appearance under the bonnet.

Will see between 200kw 230kw.

Tune car & see what you make, upgrade injectors where necessary.

Id love to know where you are getting your tyres for $125 each Paul. They must be crap ones. Entry level bob janes with 50% tread?

[paulr33]

haha sorry, thats for rears only

$250 each for hankook 255/40/17's

[ross80]

hahah oh ok..

Hey Paul, what is your thoughts on nankangs?

They have them around the corner from my house (45-235-17) for $150 balanced and fitted. Ive heard drifters use them even in competition. Though I guess grip isnt an issue.

I previously had bridgestone Re040's which were around $330.

cheers

Thats each aswell not for 2 hahahahah

[paulr33]

off topic but ive tried pzero's 255, dunzlop dz101's 255 and now hankooks 255. i never heard anything good about the nanhanks and sound like a cheap tyre to me. good rubber is generally a fair bit, i was suprised on the pricing for the hankooks
