ok this is not my own work, but i think that it will be a good help to explain whats goin on in those pipes. There is too much misinformation regarding exhaust theory. What kind of misinformation? For starters, there are a lot of people in the "Bigger is Better" camp. We're talking about exhaust pipe diameters. Even the big magazine editors are boldly smattering statements like, "For a turbo car, you can't get an exhaust pipe that's too big." Also, terms like "back pressure" and the statement, "An engine needs back pressure to run properly!" really can be mis-leading. Let's start from the beginning. What is an exhaust system? Silly question? Not hardly. Exhaust s…

hey guys, i have hooked up my 2" straight threw with one muffler, but I'm looking to upgrade to 2.5" i want it to sound nice and deep and not really raspy like little engine with big exhausts, should i go for a resonator and cannon style thing or a box muffler or something different, i want to achieve a deep note like what you might hear on some skylines and ditch the poo sounding t motor noise buy the way tis is on a turbo 2t motor

Hey guys, Okay before you just shut this down and giggle to yourself, My girlfriend has a Vt acclaim and I'm really keen on fitting the electric seat's to the rolla. I know how bizarre it seem's but I was wondering if anyone know's the rule's and regulation's for these. I have heard that as long as the original rail's fit with no adjustment's then an engineer's certificate isn't needed. Could anyone confirm this please? With this in mind, I would also at the same time like to re-upholster the material on these seat's to suit the interior of my car. I need a very talented upholsterer for this and any help would be muchly apprecia…

just wondering when people convert from 4agze to 4agte 1.does the computer run the engine well (such as fuel & timing)??? 2.whats your experiances??? 3.i have a tunned aftermarket ecu for a 4agze would it start and drive well enough before a full tune on a 4agte??? any1 done this or turboed a 4agze and took chargwer off as I'm intersted how your car went as its a common modification i would love to know how your cars went cause I'm guessing the vacume,time to hit boost,timing and fuel would differ from supercharged to turbo thank you

OK Folks, I am building up a 4AC to go in my KE70, Eventually this will become a Rally Car, yes I know its not a 4AGE. (don't get started om this one, the categories I am planning to run do not allow it) So I have managed to get myself some 40mm Dellorto DHLA Sidedraughts to go on the 4AC, I know HKS used to make a set of intake manifolds to suit webber/dellorto carbs. So my question is, does anyone know how to get them, have made a set etc, can lend my diagrams to making my own etc, I have a good engineer helping on this one, however if anyone can lend their advice to me is appreciated and also easier. Also since we are on the same side of the engine, I need extr…

Question- How on earth do i remove all of the sound proofing/body deadening from the floor inside my rolla? i'd be buggered if i'm going to spend two days with a screw driver slowly picking away at it. I've been told that i need to use some sort of heat gun? WTF? Any help would be greatly appreciated! cheers phatke30!

G'day Does anyone know a good place in Sydney where i can get my Carbies tuned? I want to try and find someone who really knows what they are doing Currently i think they are running rich and the idle is set too low All help is appreciated - Cheers

I had 30 thou shaved off my 4k head to raise compression. So i put it all back together today but now there is a really loud tapping that sounds like its coming from the top end its, not valve clearance or the rocker gear because i adjusted the clearances until they almost had no gap at all but it wouldn't go away so i put another rocker gear in and still the same I'm thinking maybe because of the head sitting lower the push rods are on a different angle that makes them noisy but I'm not sure what do you think?

my 3kc is pissin out oil.. ill park my car some where for a decent hour come back n there a small pool of oil... suggestion on where to look?? seals etc,, cheers :hmm: cam

My USDM one: The JDM one off Terry's 86 racecar: Comparison pic: Now for part numbers:- JDM PIPE: 16278-16020 USDM PIPE: 16278-16050

hi am i able to swap a ke30 borg center and pinion and put in a ke70 i blew a diff and don't have another i have read the faq but didnt really understand thanks

My 4k blew the head gasket so Its a good time to get the head shaved to give it a bit more power how much would you recommend taking off I'm thinking around 20 thou but tell me what you think. :dance:

It appears that there is f@$k all decent 'sporty' shocks available for the KE70 struts. With most companies offering OEM replacements or nothing. So for those that haven't changed over to sprinter/corona/T18 struts. What shocks have you put in the front of your KE70? So far I've only found these companies to supply shocks to suit: Gabriel Monroe ACDelco Pedders Currently thinking either of the first three and f@$k pedders off.

I am halfway through a manual conversion on a ke35 I am trying to pull the pedal box out of a KE55 :yes: the bolts seem to be in akward spots Do i need to remove the dash or can it be done without doing that YOUR URGENT HELP IS APPRECIATED

I got a red top 4ag and I'm not getting any fuel out the injectors. theres plenty of fuel in the rail. and i put noid lights in the injector plugs and they work. i checked the ohms on the injectors and it reads 14.8. can anybody tell me whats wrong.? or something else i should check? is there any other way to check if the injectors are working or not? The fuel pressure regulator is good as is the fuel pump. any help, links, or anything would be HUGE! THank you.

hey i just lurked the first 10 pages of tech forums and couldnt find what i wanna know so here goes... firstly, I'm gonna put coilovers in the ae71, I'm thinking s13, with s13 brakes...as I'm a nissan boy :( what is involved, IE: control arms changes and what not?? and is it au falcon springs with now shorter shockers for the rear? second, the diff, will be welded i guess, needs to be disc break rear and keep same stud pattern. what should i use, T-series diff?? if so what has to be changed to put it in?? also will the falcon springs still work with that diff?? will neede to be able to support ca18det amount of power also any help will be awesome thanks…

I have recently purchased a 1974 ke20 and am looking to change the stud pattern... I am not knowledgeable about diffs, brakes and axels but hopely you guys can clear a few things up... Q.1 - If i were to get ke70 axels and brakes, will they slot straight into my existing diff? Q.2 - (don't judge me) - but rear ke70 axels are discs right? Q.3 - Spacers - I know they give you wider tyres but do/can they change your stud pattern (4x100 pcd to 4x114.3 pcd) ? Q.4 - Can i change the whole rear end (diff, axle and brakes) from a ke70 into a ke20 with no dramas? I would appreciate all help and knowledge, Thankyou Will

here's a couple of photos that show why Toyota went to a 42mm big end journal in the 100 kw engine. this engine has only 160,000 km's on it and it wasn't driven hard?

Hey. :) I'm in debt from buying Superlites (still), and I'm getting bored not being able to spend money on the car... so I was just wondering about ways to clean up my engine... as in like the parts and stuff. Something to do at home just to keep myself busy... Cheers.

Permatex 1B liquid gasket - if it wasnt solid in 12 hours would you say i have a dud batch or does it take longer? (tube says fast drying but doesnt list a time...i was expecting only a few hours..) :)

How much for a good 12A to go in a 1200 coupe...

I just aquired a 4K engine which is currently running a bit rough so i thought i would pull out the spark plugs for a look see When i unscrewed the plug, the sleeve/surround came out with it Is this normal? If not does it need to be fixed? How? And also, i want to get a good set of plugs to suit the engine specs as far as i know it has standard internals except for the cam, twin dellortos & extractors Any reccomendations for plugs would be appretiated Cheers - Andrew

didnt get to bed lastnight until about 4am just doing the usual chilling as uni holidays are on. and this morning i get a knock on the door and someone has hit my car. i originally thought it was a joke as i have heard it before as my paddock basher ke70 doesnt have the best of good looks. and i went outside and it was actual hit and the lady that hit it was just standing there giving me her details. she was in new pajero. so theres some free cash for me :) ive been looking for an excuse to buy a new car. its bit of a fairy tap.

got these from my dad who found them in his shed of a house he just bought!! Anyone know what they are off an if there worth any thing? they have a rotor simbol on them :dance:

Hi all just finished converting my 5k motor from twin down draught webers to twin 40dcoe webers on my ke20. Just want to know what most people do for air filter setup, due to lack of room. I have bought a pair of filter socks in the smallest size but they seem to be to long, i am thinking about cuttting them in half to fit without being squashed up. also what do people do to support the webers and manifold because of the weight of the carbies. All comments and pics would help. :hmm: Here are a couple of pics of my weber setup.
