People wanting to race

[NA_R33]

hahaha, yeah i cant wait till the engine is done, money is the real issue though, its gonna cost me heaps, so its gonna be a slow project. but will be well worth it. Im aiming to have it done early next year.

Do any of ya's know your 0-100 time?

mines roughly 8.2 sec

[nismoman18]

i got a 7.26 and a few 7.6's other times around 8 (slow launch and shifting before cutout) but im hoping to do lower then 7's in the future

[Driver]

Does your hi flow cat make much of an improvement?

[nismoman18]

yeah it does, ive got it flanged so i can put a replacement pipe in. That makes a real difference, once the car hits 3grand it just moves, with the cat on it kicks in from about 4500rpm, im gettin a custom track exhaust, from extractors will split in to 2 11/2 inch pipes and exit at the side will make a hell of a difference i reckon

[Driver]

I might go see if i can get a 2 1/2" hi flow cat from a wreckers

if there not too much of a rip off..

[nismoman18]

get stealth cat (hollowed out)

[Driver]

What was the size of the outlets of your old cat convertor is it 2 1/4"?

[Driver]

do u mean gut the cat?

if so i know its illegal but wouldnt it make things worse since its NA

[NA_R33]

yes an NA car does need a certain amount of backpressure but this is already happening through ur headers and the rest of the exaust system, gutting the cat deristricts the exaust a fair bit and is definately a noticable power increase, those extractors where 285 bucks plaus 150 for fitting, the most worth while mod i have done yet.

[nismoman18]

by keeping the exhaust at 2 1/2 it keeps the back pressure at a good level, gutting the cat is illegal of course and it does screw things up abit u have to gut it and put a stealth pipe in it, visible as a cat, but its a pipe inside a box. my old zorst was 2 1/2 all through

[naiwiboo]

i've got an auto r33 - but its the 5 speed auto version with a really short 1st which helps acceleration - i get around 7.5-7.8s for 0-100 - i've god k&n pod filter with divider in the engine bay, that's it (running 98 RON petrol all the time and service every 5,000 with anti-friction oil - i reckon it helps!)

i beat a wrx with a bov one night - that was pretty funny i think the guy was a sh!t driver tho, and i can keep up with my mate's ca18 silvia (rebuilt and boosted to 12psi)

8.2 sec is a bit slo for a '33 - even an auto - do u torque brake?

[Driver]

i think its slow too!

i wana go against an r33 with the same mods or less and see how i go..

do i torque brake?

i duno wat that means

but if u mean start of with ure foot on ya damn brake and on the gas and take it of brake

then yea thats wat i did to get that time.

[nismoman18]

thats what it means man! strange that ur car is quite slow shame ur in perth or else id race u right now

[Driver]

hehe cool

damn my car

if i had the money id get it dyno tuned to see if thay can iron out any problems

[nismoman18]

maybe its just like that man! what size wheels are on it ? and tyre profiles etc ?

[Driver]

i got ROH 17" wheels

i duno the tire size

it came with the stock wheels when i got it.

but yea its been like this since i got it

[nismoman18]

try doing a 0-100 with the stock wheels, since i put my 17's on it has lost a little accelaration (diameter is slightyly bigger) i got 225/50/r17 on mine, if urs are 45 or lower then it really shouldnt make a difference, but tyres and width can also make a difference. u lose out on speed but handling gains heaps:)

[Driver]

The only thing that i found was different was i actualy have grip now and that its a tiny bit more harder to turn the wheel

me being slack

Im fairly sure the wheel diameters of both sets of wheels are the same tho ill have to check it when i get home.

[Driver]

Yeah there pretty much excactly the same size at the stupid stock non turbo wheels
