20 valve engine conversion, help.

[JMR_AW11]

I still maintain that (IMO) the mk1 MR2 only needs a bit more power and it also needs to lose some weight to really get the balance right.

I also think that the 4AGE engine is a key reason I like this car so much.

I'd certainly like to have a go in a 20V converted mk1 and especially if the car had been modded to lose some weight. Maybe the OP is thinking along similar lines?

I've had a go. It's good but definitely not worth the cost of doing it for the relative little you gain.

What about a 3S-GE, loads of them about (I am sure Mr Woods is tripping over them in his yard), very cheap, reliable, more power and torque than any of the 4As, just a bit heavier.

I am sure with a small amount of DIY mods a decent late 3S-GE could put out as much as 180bhp, the engine would also feel a lot revier than it does in the Mk2 due to the serious reduction in mass between the two cars.

I am even persuading myself here!!

[PW@Woodsport]

We did a 3sge engined one a few years ago, it was the rev3 174bhp, but the extra weight seemed to cancel out the bhp gain. Add to that the fact it takes the same effort to install the turbo version makes the 3sge a bad choice in my opinion, although a beams would be good.

[aw11rally]

Is there much difference between 3S-GE and BEAMS? I was having a look for info on that engine a few nights ago but could find very little. All I did find was that it is not non-interferance, so I presume more compression and lumpier cams, is the intake different too?

I do agree that weight would be an issue so an extra few horses would be nice.

I am sure there is a BEAMS on ebay at present, expensive though.

[Lauren]

Around 210bhp for the BEAMS IIRC. VVTi on the 3SGE basically in it's late incarnation.

I still think a K20A would be far better, but it's not a toyota engine, so would make it a right old faff to fit I'm guessing.

[PW@Woodsport]

I could definately fit it if someone asked me to.

[aw11rally]

sshhh dont temp me!

K20 + JacksonRacing SC kit.

Years ago I used to fit them to Elises/Exiges, so it's very much do-able.

Have you had a seat in any converted AW11's out of interest?

[aw11rally]

Personally I find my 1bar mk1.5 vary balanced and in no need of weight loss. What about you ollie?

You what?? Do my eyes deceive me? Lauren modifying a vehicle beyond standard factory spec! I thought standard was always better?

I would dearly love to get my hands on an Elise and stick a 1mz v6 in, i think that combo would be amazing.

I work on these for a living and also fit audi 20v turbo conversion
The three conversion for a lotus elise/exige are

1- honda k20
2-audi 1.8 20v turbo
3- duratec 2.0 +2.3

honda k20 are getting hard to come by now as they was only fitted into a civic and cost £1700 to £2500 if you can get them complete.

I have had a drive in an SC conversion on a UK mk1 MR2.

I think it was a poor example of this conversion as it didn't handle very well at all. I think it needed newer or better suspension. However I did also think the engine had lost a lot of appeal compared to the NA although it was notably quicker as the bigger pulley had been fitted.

I simply prefer the power delivery of the basic 4AGE

That's not a conversion though is it Jeremy, the Mk1 SC exists from the Toyota factory.

Get yourself a go in a 1.5 or V6 powered car and then decide if it has upset the handling or ruined the balance. I can assure you it does not, just bucketloads more power whenever you want it

What's your opinion of a nice lightweight V6 in one of these then Wayne? The 1mz is a very light engine and very torquey.

Hi paul, also forgot there is a vw r32 engine conversion too, anything is possible if the thats what the customer wants.
Its like with the audi 20v turbo, they always want more and they are aload of aftermarket bits for these engines

I'd love to have a go in a 3SGTE powered mk1 but I'm pretty sure I wouldn't want to own one long term. I've been in several 3SGTE powered Toyotas and the engine doesn't inspire me. It's certainly got loads of power though...

This really is just my opinion but putting a bigger and heavier engine into the car isn't what I want from a mk1 MR2.

There are times when my 4AGE is a bit of a chore, eg pulling away up a hill etc but once the engine is spinning and the car has some momentum I find the car to be a delight to drive and for me the 4AGE is an essential part of this.

The handling balance and the 4AGE engine are probably the main reason I've kept hold of my mk1 MR2 for so long. I can afford a much more expensive car but the basic mk1 MR2 still does it for me as a weekend fun car

I was doing it back in 2004, so sometime ago now.
