Not only have I not had any of the issues you've mentioned, the other people I know of with 2gr cars (there are at least 3 on this forum and a number more on FB), have not had them either. Of the things about running a 2gr MR2, issues with the engine are not among them. People have other MR2/swap related whinges (gearbox too short, loom faults, rust, seized brakes, etc), but pure engine mechanicals that you're referring to - are very very rare. I'll ask again - where have you got that impression ?Absu wrote: ↑17/08/19 23:42Hi,
thanks for your replay and input I really appreciated that and I'm glad you didn't have any mentioned issues with your car:th: However..the question is?how many miles you've done so far since 2012? I my experience this kind of cars in general seem to be don't do many miles at all (you can check MOT history)some do 500 miles in a 3 year some 1000 miles.. I had a conversation with one guy who had mr2 with 400bhp (so he said) he said that his car never sees the rain and winter and is his pride and joy.
Well..I'm different is my pride and joy on daily basis..when I've build the car and put on the road..speedo was reading 71,464 kmh..until 79500 roughly after speedo mph conversion and now is about 87+ from 79500 to 87+ is all in miles!and during this mileage I'm on my 3rd set of rear tyres! I'll make some video at some point..
By the way,do you know whats the engine weight with the transmission of 2gr-fe or 2gr-fse compare to 3sgte?? I know that we can ditch aircon pumps on both. In my experience I would choose h22 vs K20 +4 series.. Same 3sge over any 1zz and 2zz and 3 sgte of any 1mz and 2gr and the list can go on. Earlier engines was much more reliable in many ways..maybe less powerful but that easily corrected.
Yeah..I tell you the truth I've never been in MR2 with any v6 1mz or 2gr.But I'll always consider 1mz is utter downgrade from a turbo.
I've owned this car since 1999 and I've done around 38,000 miles since the conversion in 2012. It's not generally a daily (I live and work in London), but has been used daily to get to remote sites, has done a number of long distance (~2000 mile) European road trips. It is as reliable as the 3s-ge that came out of it and largely because it doesn't have to work very hard most of the time.
Engine weights - a 3vz is heavy, a 3s-gte is just about as heave heavy (you have to factor in a turbo and charge coolers and stuff), a 1MZ is lighter and a 2GR is lighter (as they are both alloy). Most people use an e153 gearbox on a 2gr, but the S54 N/A box is also used for V6s (extending gear ratios is a little easier and is a a good idea).
I have to be honest with you, but an "as Toyota intended" (i.e. fully stock) rev2 turbo will struggle to keep up with a 1MZ sw20 on the road (the extra 20bhp headline figure hardly helps on the road), as it's got lots more immediate torque across the rev range and that's what counts when driving on the road. A 2GR sw20 will put many length on you.
BTW, you can't use a 2gr-fse.
