[Mk2] [NA] whats the difference in performance in revision 2 and 3 na

[minty0_10]

i know they are diffrent engines and that the rev 2 are around 156bhp and the rev 3 are around 175bhp

anyway iv just sold my 93 rev2 that had 140k on the clock the car went and would pull 140mph (where aloud)

ive just bought a rev 3 with 120k on the clock witch struggles to pull 125mph.

i thought the top end mph would be more or less the same but i have to say i think the old car pulled much better throughout the rev range. both cars are uk spec.

iv had 5 revision2,s in the past so have a good idea how they should go go.

Not a big help but here it goes.

Never been in a rev3 although from what I read, it is a bit heavier so slower from the standstill than a rev1-2. Although that shouldn't affect the top speed which should be a little bit higher on the rev3.

Now my idea: when I bought mine, it hardly would go over 140mph. Now after a year giving it the right treatment (foot to the metal and no upgrades but a normal maintenance), I saw 155 in the odometer. Very impressive...

So it might just be the case that yours needs to stretch it's legs.

My 2 cents.

I think Rev 2's are 158bhp and Rev 3's are 175bhp. However the rev 3's are heavier so have a slightly slower 0-60 time. Rev 1's coupes are 118 bhp (i think) but they have a faster 0-60 time than both the rev 2 or 3.

[pintovit]

Nope, rev1 is 158 bhp also. American version 2.2L (3SFE) is the one with 116bhp. rev1s are the fastest of the bunch except probably for rare rev5 beams ones with 200 bhp or so.

If your rev 3 is noticeably slower than the rev 2 then it probably needs a bit of sorting . Check the lambda sensor and water temp sensors are all working well. Give it a service with new oil, oil filter, air filter, fuel filter , distributar cap , rotor arm, correctly gapped plugs and maybe even leads . And I always recommend giving it a blast through with 10k boost or the like to get rid of some carbon build up in the intake, chanmbers and exhaust .

The UK had 2 versions of the rev1 - the 119bhp 3sfe coupe (no foglights or spoiler), and it also had the 158bhp 3sge version.

Never in a million years will a rev1 uk coupe (118bhp) be quicker than a rev3 (174bhp) 0-60. It has a third more horses and a far better engine design.
A rev3 will out accelerate a rev1/2 although by a relatively small margin, but will out drag a rev1/2 noticeably once in 5th and into three figures.

Didn't know about that. Thought that the 3SFE was for the US only. My mistake then.

[minty0_10]

well i treated my car to a full service oil and air filters oil leads and plugs and still no difftrence i have noticed throgh the water temp says on half way while the rev 2 car was more around quater.

im i right in thinking maybe the cat or exhaust could be bunged up as i bought it from a guy who said he never realy booted it in the year he owned it

[JOHNM400]

Check the ignition timing. I dont know why people suggested changing the oil and filter. Yes its good practice when you buy a used car but it wont affect the performance,certainly nothing noticable. The Ignition Timing is probrably retarded.

the rev1's are nearly half a second quicker to 60 than the rev3's mate!

[ryan]

My rev4 n/a is slower than my old rev1 n/a
Just done plugs and cap, will get timimg done next. Up any fast incline the car needs 4th or 3rd to accelerate. My cousins rev1 is far more perkier in this situation

[JAP BOY]

Rev 1/2 will be quicker also i'm not sure of torque figures but i know of a few guys who have got around 152lbs of torque me being marginally close with 149lbs of torque on my Rev1 N/A when i had it!

[minty0_10]

i always give a car a good service when i buy it so that so problem i wasent really expecting it to make a difference but how do i check the ignition timing?

from what ive read then so far the rev2 cars seem a better car all round when you think of the difference in price to

[marcnoonan]

Hi,

Always thought that the Rev3 would be the quickest. However, if it's running the car in that makes a difference I've thrashed the duck out of my Rev1 UK MR2 for seven years, always to 7200 before I change gear ( only had the gearbox fixed once) and easliy hits 137 in forth and the max I've had is 160@6800rpkm with a slipping clutch.

Then again the gearings may be different as I hit:
1st 40
2nd 70
3rd 110
4th 137
5th 160+

I know that others have to change into 3rd at sixty so the higher accelaration given by the gearing may be cancelled out by the earlier gear changes needed? Just logical thinking as I'm no mechanic........but fortuantley a few of my family are.

Check the 0-60 times of the rev 1 low bhp model and you will see that they are quicker than rev 2's and 3's, the rev 2 0-60 times are also quicker than the 175bhp rev 3. I didnt beleive it till I saw it. The rev 2's and 3's and some later rev 1's must have had more wieght to them or something.
Marc, what mods are you running cos theres no way on earth that you can get 160mph out of any rev NA mr2, your speedo must be well out otherwise.

[marcnoonan]

Hi Blue,

Nothing more than an air filter and one of those ebay resistors at the time (i know it wasn't that). Speedo's fine and I was running on 16's with 45 profile, if that makes any difference, but thanks to an M3 going past at about 150 on the M1 at 3am I managed to crank her right up on a straight too. It hit's 137 in forth no problem every time, so I can't see why the extra 23mph is soooo unexpected for fifth, although it seemed to take forever over 150 and wouldn't push past 6900 revs.

Is the gearing on yours the same as mine?

[rowan_rev1]

Check the 0-60 times of the rev 1 low bhp model and you will see that they are quicker than rev 2's and 3's, the rev 2 0-60 times are also quicker than the 175bhp rev 3.

no your simply wrong sorry! the 3sge model (158hp) was quicker to 60 than the rev3+. james off of mr2oc.co.uk and i are constantly racing and my rev1 gltd is FAR quicker than his is!

[minty0_10]

ow well looks like my owner ship of my rev 3 is going to be shorted lived must say im disappointed in the performance:( back to a rev 2 for me apart from the rear lights i cant see any point in forking out the extra cash in keeping it

so whats it worth 95 t bar m reg uk car 8 months mot 6 months tax 125k clean paint work red not pink like a lot leather small tear in the passenger seat
clean alloys and all newish tryes

Official Toyota figures for revision 1/2 0-6 is 7.8 seconds, versus 7.7 seconds for the revision3.

The difference is fairly marginal between the two, but it is there and the balance of power is in favour of the revision 3+ engine. Just check out the MR2 Challenge grids for the mk2 and you'll find all of the front runners use revision 3 engines.
