yeah ok
i just get sick of hearing about sr20 this and sr20 that. you know what i mean. there alot of other engine around some alot of wich will out perform the sr20 but no one seems to care, for them it's all about an over rated name.

You have a point there are many more capable engines; RB26Dett and FJ20 but what is so good about the SR20 is it's small, easy to source and is not entirely difcult to fit to cars.
Personally i love the RB26!! yummmmm

again all nissan engines. and all get used in to many conversions.
sure they make good power but there are still other engine that can out perform them

take this escort. sure stick in an sr20 and make al this power.
or be different and use a BDA or a BDG or a BDT. or a cosworth YB. all of wich will bolt in with the smallest of mods and make just as much power if not more power in th case of the BDT and cosworth YB. pluss you get the bonus of keeping the car all ford.

8 grand... for like 4 grand i can get a half cut rx7 from japan and drop a rotory in the escort lol.. with 4 grand to spare i can dump a turbo on it and modify the shell of the escort lol..

just wondering.. why isnt there a 4 cylinder forum.. dont many of u guys look into smaller engines?

for 4 grand you could import a RX7 front cut. then you will have a front cut on the ground next to an escort.
by the time you spend all the rest of your money up grading brakes gear box, diff and suspension. you will then have an escort that stops good and goes around corners, with and XR7 front cut still sitting on the gound next to it.
engine swaps of that nature are not cheap. you spend a lot more than 8K on an engine swap if done properly and get it engineered

just remeber a piston engine of the same power will last a hell of alot longer

yeh but to get a piston engine to that amount of revs and horsepower... ude really be pushing it.. when it comes down to it , if u really want a car to do a quick 1/4 mile u cant really beat the rotorys

revs isn't every thing mate.

and the rotories you see doing good times don't last very long. there are a few here in town that a fast but the things get rebuit avery year and still only manage 13 sec. if you want a fast escort you to talk to H.P.E in england.
try 12.2sec 1/4 mile with a carb fed 2L pinto and manual gear box. he has one and both of his sons have one that are that fast and i'll put money on them out lasting a rotory that is that fast

Thats not a fair comment and Ill tell you why. For every 3 revolutions of the output shaft, the rotor itself only turns once, hence less wear and less friction and higher revs. So as the theory goes a rotor should outlast a piston engine, and they do compared to thier piston engined counterparts that share the same rev range, but when compared to a lower revving I6 or V8 that produce huge amounts of torque down low, and hence less friction and wear, of a*** they wont last as long. Also rotary engines arnt as easily modified as piston engines even though the theory behind it is simpler, people just dont get it right. A testiment to this is the factory triple rotor that won the Le Mans 24 hour several years back. Un reliable cars dont win 24 hour races!
I have an RX7 and it has stood the tests of time as its still on its original motor from 1982 8-)

hey guys. i know this isnt a 4 cylinder forum. but i didnt see one...

anyway. whats something affordable i can do to my 1.6 that will make it get around a bit quicker. im not talkin a superfast. just sumfin with a bit of kick.

if u have any sujestions please post them.

thanx: Lee


Sell it and buy a Ford. :lol:

On a serious note: Exhaust, exrractors, filter, spark plugs, leeds and a bit of weight reduction. Would be good and very affordable.


Good thinking! Sell the Escort and buy a FORD Escort :)

Regarding the SR20DET comments - They're an all alloy motor, they are very lightweight, lots of gofast bits exist for them, everyone knows how to tune them and they aren't ridiculously expensive - a newer black top goes for around 3.5-4.5k complete with ecu, turbo, loom, gearbox, clutch etc.

Dont forget the RB motors are alloy head but cast iron block so you've got an extra penalty in weight there, as well as having two extra cylinders worth of weight penalty. They'll make a lightweight car handle very FWD-ish.

Be different, if a Toyota 2JZ-GTE fits, I'd much rather that for a street car over an RB26DETT just for regular driveability as well as the ability to tune it off its nuts.

Jaysen, I thought it was the other way around, correct me if I'm wrong. I thought the rotor spun three times per revolution of the output shaft....?

Rotors that aren't worked off their nuts and no more than mild mods such as a little extra boost, exhaust and intake will travel over 200,000km with regular thrashing as long as they're serviced at the recommended intervals.

Yeah i second these comments. Rotaries really are incredible engines. Of course they have WELL documented reliability issues but not as much of a problem these days. Unfortunately the apex seals will always be a weak point, combined with the difficulty of lubricating parts inside the combustion area.

Yeah a highly-tuned rotary is going to have reliability issues but so is a highly-tuned I6 or V8. Look at people with INSANE I6/V8 setups and they are chopping/changing parts just as often as a rotary enthusiast.

Besides this point - if you're after outright performance then reliability doesnt matter. So long as the thing runs for 13 seconds at a time.

Lol, not to be picky but the 787B which won lemans was a 26B motor - quad rotor, 2.6L, variable geometry intake (have a poster in my living room :wink: ).

It won outright. Rotaries were then banned from most forms of international motorsport. Seems to me that they wouldnt have been banned if they were 'inferiror'....

ok a few things... what the hell do u think an escort is...? one person sayinf.. stuff that buy a ford.. and sell the escort buy a ford escort.. what the f*ck are u talking about lol..

on a lighter note. i went to a escort place today and spoke to the guy working on my car about making a super quick esky.. even he says hotting up a 2L would be cheaper then putting a "fake engine" (rotory) into a escort.. his backup was they're fairly unreliable aswell.. heard a few different stories about that...

but yeh so now hes got me thinking.. i might buy a escort shell off him that hes got sitting. dead strait and the paint jobs allready been done.. the guards have been cut to suit big flares for big wheels ;) which is what i want anyway...

and about the engine i'll prolly stick to the ford motors.. buy a pinto or something like that and throw money at it every now and then.. like a project car. me and my dad will work on it...

but thanx for ya comments about the different engines.. i'll still keep the rotory in the back of my mind.. but i doubt ide get one over a 2L. especially with the cost of fuel. and i aint exactly a millionair.

cheers: lee

if you want some good info on building the 2L pinto PM me and i'll email you some very interesting stuff. and a few good books you should get.

This I believe is true, its been a while since I read up on it 8-) As for rotaries being a fake engine, tell this peanut to grow a brain cause they have countlessly proven themselves on the street and the track. All this asside, I have now retired my rotor as I find the outright torque of my I6 more exilerating, but I still love it just the same

No this is somewhere that I have also run into heated discussions about. The simple fact of the gear ratio between the stationary gear mounted to the front, intermediate and rear housings and the ring gear in the rotors is at 3:1 there fore the output shaft MUST rotate 3 times for every 1revolution of the rotor.
Anyhow. enough about this as we are on a ford site and ford never played with rotaries, however holden and chev did
