Buying an mr2 turbo - advice
Hi all,
This weekend I am purchasing a rev3 mr2 turbo. See link below
https://www.autotrader.co.uk/classified ... rchad=Used
Do you think it looks like a good one? And a good price?
The mods are perfect for me and would save me money over buying an original example as I would buy these mods anyway
Anything crucial I should be checking for?
Thanks
Tom

Re: Buying an mr2 turbo - advice
A mk2 cannot be a 2004 model.
Also, in my opinion; it isn't worth that kind of money, the mods listed would cost you £2000 at most.

Re: Buying an mr2 turbo - advice
That v6 looks nice!
My plan to to tweak to 300bhp fairly cheaply however so 4 pot better suited to me
I have said I am not willing to pay more than £8k. I feel this is about right considering the history and the lack of rev3s for sale at the moment

Re: Buying an mr2 turbo - advice
Well thats probably your first mistake. 300Hp does not come cheaply or easily from these.tommy10101 wrote: ↑23/11/19 11:38

For starters it doesnt even come easily from a modern 2 litre with full variable valve timing let alone something out of the 1990s.

Re: Buying an mr2 turbo - advice
Well that’s the opposite to everything I have ever read about these cars so far
I thought these engines were very strong and over engineered and thought 300bhp only needed exhaust, induction, intercooler and turn the boost up a bit?

Re: Buying an mr2 turbo - advice
The v6 is nice but I want the turbo power and want it more original
Was just posting in the hope someone would point out anything bad about this car or somthing I have missed which would give reason to avoid it etc

Re: Buying an mr2 turbo - advice
maybe test drive a V6 then pay double for a Turbo if you think its worth it

Re: Buying an mr2 turbo - advice
Been there and done it back in 2008 with my Rev 2 even with alot of bolt on mods including a hybrid CT26 which is now performing like a CT20b the gains on an actual dyno run were up 25Kw from a stock baseline run that hardly anyone ever does before any modifications.tommy10101 wrote: ↑24/11/19 19:20 Well that’s the opposite to everything I have ever read about these cars so far

Yes its all over the net but most of what you read is rubbish and not supported by Dyno runs. My favourites are getting a run and then making a few more minor mods after it and then claiming its at xxxHp like the "exhaust was leaking". If you want 300Hp at the wheels on a true dyno its not easy and no you cannot add 20% drive train losses after a disappointing dyno run to fudge your 300Hp at the flywheel either.
The engines are very strong and the core components like the crank, head and block are retained but just about the rest goes in the bin. "300Hp" and certainly a reliable 300Hp is not as easy as you may think.
What I do like about the MR2 is the low weight relative to the modern cars. at 1390Kg its hundreds of Kg's lighter that a standard sedan and even 250Hp "Feels" like 300Hp anyway and the CT series turbo spool so early they are making boost from as low as 2500rpm so the power delivery is nice and linear as your not waiting for the turbo to kick in.
Also a big difference in the way power is delivered between the Turbo and the V6 put in these so it comes down to the way you like to drive. I like 6 cylinder N/A's but the Subaru Boxer engine is no ordinary 1990's V6 designed to be put in a truck.
By all means buy one, put it on a dyno before you start doing anything to get a baseline Hp and then start spending the money. Just be prepared to have deep pockets. Not saying it cannot be done but its not a simple as people make out.

I have seen loads of rev3 tubbys on dynos with the quick mods he is talking about above 285bhp fly and most are close to 300.
3 I know are at 301-303bhp (with charge coolers).... all on same very reputable dyno.
your rev2 tubby engine is a different matter to get to 300bhp and yes you need to spend more on rev1/2 to get same gains.
totally agree with your power delivery between V6 and Tubbo... initially I can stay with tubby in straight line but when the turbo comes on line and with the extra revs in each gear they walk away from me.
V6 IMO and a few others make better fast dailies than turbos, no need for V power and more miles per gallon.
if weekend toy it comes down to how you like the power delivered.

Re: Buying an mr2 turbo - advice
Like I said tho, do a baseline run FIRST and compare that to the factory claimed power.
Then do your basic bolt on mods mods and dyno run it again on the SAME Dyno and see what "Gains" you actually get. You will be lucky to wipe out the difference between your first dyno run and the claimed factory power.
You CANNOT add stupid high transmission loss figures to the Dyno result to get to the magic 300Hp. Sorry but you will be running like 19psi plus on the CT20b and you still will not be at a true 300Hp at the flywheel. Its no going to happen. Dont get me wrong, the 3S-GTE is a great engine I love it to bits and it has massive potential if you want to throw some dollars at it but regardless of what you do to it, the engine is now old technology from an engineering point of view.
If your going to pull the engine and completely rebuild it, do some flow work and look at different cams and valves etc, then sure I can believe you would get very close but that is not technically just simple external "Bolt on modifications". The stock ECU and injectors have their limits and you find them pretty quickly as you increase the boost.
Are the "bolt ons" worth it, hell yes I had so much fun modifying the car myself but on reflection was still lucky it didn't go bang as not everything was done in the right order. There are a few easy gains to get, then IMO give up chasing the numbers as money is best spent on quality tyres, brakes and sorting the suspension because even on stock power these cars are QUICK.
