Hi, just wanting to know what needs to be done to get a 14 second 1/4 mile? I'm currently running a et pulsar with a t2 turbo, exhaust system, pod filter and a intercooler what else needs to be done to get this time? Please give me mod list and power levels? Thanks guys

All i had was a t25g on 15psi with an intercooler. 2.5'' dump pipe and exhaust until under the sump into a standard exhaust. Oh, and a BOV, which adds nothing... That was on a red top motor and i ran a 14.687@152.41kph. Simple!

The black top motors from my experience don't seem to handle boost as well. I had my red top up to 22psi without any dramas, but on my black top it would struggle with 13psi. Most probably a timing issue, but still there is something special about the red tops.

I'd bolt up a t25g, fo a full 2.5'' exhaust system including dump pipe. Add an intercooler, maybe a mild cam and with a bit of luck you should crack a 14.5 with about 15ish psi

I think the red tops are jap spec engine, Sounds like a awesome setup!.

What about a vl fuel pump as well? don't wanna run boost over 12psi as i don't wanna change the ecu or anything like that. So, 13psi is at the limit with stock internals with the black top? What about suspension wize leave it sock or would it help to add lowered springs? of course tyres how would 15 inch rims with low profile tyres go? Any driveline issues? Would i need a heavy duty clutch? The reason I'm asking my brother's and i are going to willowbank at the end of the year and i wanna keep up with them or even show them up. I'd be very happy with anywhere in the 14 sec on the 1/4.

My wifes old ET ran mid 14 with just t25g, Intercooler and exhaust on about 12psi. Pretty easy, if the motor is in good condition and doesn't have a 'bad head' on it.

Sounds like a goer. I'm gonna get it checked out and a tune up. Thanks for the info guys.

Same motor save for those funky looking rocker/cam belt covers and inlet plenum.

Dont go giving them too much credit.

I also have a sneaking suspicion that they dont have the decent (Nismo) head which Aus motors have standard.

I'm speaking from my experience E. Im not to sure if you have played around with one or not, but all i can say is that my RRC is alot better than my BRC.

Some stiff springs will definitely help you keep the front end down and gain traction, but i did my 14's with standard.

If you have a good condition motor, really you can get into the 14's with only $1000.

Yes that's what I'm talking about! Anyway i might be buying a bottom end it's got a few goodies and it made 150hp to the wheels on 15psi. Should be good if i get it.

Can anybody in the Gold Coast help me put this bottom end into my et pulsar? I'm willing to pay but i can't give u much only a hundred or two.

14.99 1/4mile:

Stock!, engine, manifolds, ECU, injectors, clutch(possibly).

Decent, exhaust and intercooler. 12-14psi

14.00 1/4mile.

Stock, engine, manifolds, stock ECU.

Decent, exhaust (min 2.5inch), intercooler (min 450x300x50mm), clutch,
15-18psi, sticky tyres, some sort of extra fueling (extra staged injector,
or adjusted fuel pressure), 50mmT/B.

Have a look at my members ride, it has a performance breakdown over the years and what time I have run with what mods.

Like I said M8, they are the same engine, they just have a couple of funky bits on them.
I have one right here (less funky bits)

If your brc engine dun go as well then there something wrong with it.
This much I can assure you.

There will be valid reasons that dont appear obvious why, possibly several reasons, most likely interelated, which can result in a particular engine being a dog and another going well and its got nothing to do with the colour or shape of the rocker cover M8!!!

Mate, took a look i can't believe u got a almost flat 13 on the 1/4. Ur car is very impressive, cheers for the info

Thanks mate.
There are couple of guys on this forum in the same low 13's basket, but if you look at the mph, a good launch should net mid/high 12's.

150kw should get a flat 13 with a top launch.
