You will need the turbo alternator and starter. Starter from memory is gearbox specific (and more to the point flywheel specific - the 2 are different 3S-GE to 3S-GTE). Turbo alternator is higher output than N/A and generally larger and more robust (leaking rocker cover gaskets can quickly kill alternators due to their location and the angle of the engine). Brakes are the same 92 onwards (rev2+) on N/As and turbos.

Thank you once again.

The brakes are basically the same design as the smaller/JDM MKIV brakes - i.e. a floating caliper w/2 pistons on the outside, so they suffer from the same problems, from sticky sliders and failed boots up to stuck pistons. Beware the rears - the handbrake actuates the piston rather than having shoes inside the disc so it has a complicated mechanism inside the caliper for autoadjustment. Seeing as the brakes on both your cars will be the same, I would compare slider, piston and handbrake cable state on both cars and mix and match so that you make the best of what you've got. There's a guide I wrote in the knowledgebase on IMOC for refreshing brake sliders and dust boots but I'm sure there will be a similar one on here for the JDM Supra brakes.

Like the style of the wheels (not blue!), the blue car for sale on here is fantastic looking, I would buy that if I have the space

As it is not in the for sale thread I think I can comment and say IMO, the blue car is way overpriced and if you look around the other MR2 forums you will see why.

 

I am not looking to buy this white one, just looking at stealing his "look".

After speaking to the seller of the donor car (and finding out about the full service history, previous owners etc) Josh and I have been wondering whether we are looking at this the wrong way.

 

We are now thinking that maybe it would be a better idea to fix the donor car rather than swap everything about. The car has not been recorded as accident damaged and therefore the resale value in the future would not be affected. It would also mean that we could sell the red one and the money realised off that could be used to do up the donor.

 

OK, the donor is a rev 2 and probably not worth as much but seeing as we bought the rev4 cheap, we would not lose out anyway. Also, it would mean we had a genuine Turbo car as opposed to a Rev 4 car with a swapped engine.

 

Of course, this all depends on the cost of repair to the donor.

 

What thinks you lot?

This is nice, ready to go with very good power figures, mapped by Ryan, sell up and buy one done

TBH, that is ouitside my / our budget plus the big part of this project is for Josh and I to do what we did with the Orange car. Buy and sell bits, plan and discuss etc. A last hurrah? I sincerely hope not but if it is then we are going to have fun doing it.

The satisfaction of the first drive is great - the culmination of all the work. It's a joyous experience!

Agreed. So much better than buying an "off the shelf" ready made car.

 

By the way, I have now acquired a Veilside front and rear set of bumpers and also a rather fetch Border fron too. Add this to the turbo car and the project is taking shape.

 

What do you fellas reckon to the border front with Veilside skirts and rear? This is the modified front. Sadly he had sold the bonnet and lights as that could have worked quite well. Buts still, at the price I paid I cannot grumble.

I wouldn't have thought they'd match that well. The Border front end is quite sharp and angular and the Veilside stuff tends to be quite curvy. Your car though :) Crack out Photoshop and have a go.

 

MK7 Celica headlights is a nice mod but difficult to get right. That bonnet doesn't look like it fits particularly well. Also they've cut into the wings in order to make the bottom edge of the light match up with the swage lines in the Border front bumper. Nick Turner's car was done better IMO, the wings weren't touched:

Looking at the pic I attached, do you think a body shop could modify the Border front to take it back to a normal front without it being attached to the wings?

 

Asking me to look at photoshop is like asking Louis Walsh to play rugby league - both of us would be quite useless. :D

Assuming it was just blended with filler, yes. They'd need to rebuild the area cut out for the Celica headlamps too...

 

Remember the bit that has been blended is normally where the 'toblerone' strip is, so you will be able to bolt that plastic trim strip back on over the top of any mess.

I will probably pass on the Border front on offer and just buy a copy that is ready to fit. It will probably work out cheaper that way in the long run.

If you are going with the border front I definitely wouldn't go with the veilside skirts, the angles are all miles off. The veilside rear bumper goes with anything though.

 

After looking at loads of google images, I would agree.

Bumping this thread back up with an update of what's been happening - precisely nothing! :D

 

I was messed about a bit by the transport company but the Rev 2 turbo donor is finally being delivered to the mechanic tomorrow. I / we decided that our knowledge, skills and time (time that Josh has spare that is - I have plenty but the illness means my strength is not great) are not good enough to do the project as a diy thing. To this end I have met and commissioned a chap called Alun Jenkins (AJ Engines) from Caerleon (about 35 miles from me) to do the work and after meeting with him a few times, I have every confidence in him being able to deliver what we require.

 

I have already bought an Apexi Gt exhaust and a ST205 charge cooler and pump and am now on the lookout for the following:

 

Electronic Boost Controller

New Bosch pump for the CC

Rad for the CC

3" D/P

Rev 3 metal HG

 

I am assuming that with these fitted I should see anything between 260 and 280 BHP? Now, I have a couple of questions that I am hoping you can answer.

 

1. Alun has a spare megasquirt set up (not sure on cost yet) that could be for sale. Worth it or not?

 

2. Is it worth upgrading the ignition system to a distributorless ignition? I have been told that something like a crank trigger wheel from EFIParts - and some 1ZZ-FE coils with smart-igniters might do some interesting things but I am unsure as to the cost of this upgrade.

 

3. Would I be better off changing the CT26 turbo for the Rev 3 CT20?

 

4. I have seen a cheap emanage blue for sale. Would it be worth buying this piggy back based on the above upgrades? Or does the megasquirt cover this?

 

5. If I implemented these changes, would |I need to look at strengthening the bottom / top end of the engine or would it cope?

 

Thanks for your anticipated help.

Thereabouts. I assume you mean guestimated at the fly :)

1. Alun has a spare megasquirt set up (not sure on cost yet) that could be for sale. Worth it or not?

 

If you like covering new ground. MS setups are not very common in the MR2 turbo world, so you will be figuring a lot out for yourself.

 

2. Is it worth upgrading the ignition system to a distributorless ignition? I have been told that something like a crank trigger wheel from EFIParts - and some 1ZZ-FE coils with smart-igniters might do some interesting things but I am unsure as to the cost of this upgrade.

 

No. The stock ignition system is great for large power. The times this upgrade would be worthwhile would be a) 500+bhp or b) a situation where it's cheaper to do this than replace a failing stock ignition system (namely the igniter setup or the stock leads, both of which are over £100 new). FWIW people see better results with stock leads than some aftermarket replacements, e.g. Magnecor. The stock ignition system is good, and the leads are worth the money.

 

3. Would I be better off changing the CT26 turbo for the Rev 3 CT20?

 

Yes. Neither turbo is efficient but the CT26 has such an inefficient design it can't maintain pressure at high revs. You will notice this more with a boost increase.

 

4. I have seen a cheap emanage blue for sale. Would it be worth buying this piggy back based on the above upgrades? Or does the megasquirt cover this?

 

You could use an emanage to fix the ridiculous A/F ratio the MR2 ECUs run, but this map is for longevity and uses fuel to cool the engine down to somewhat negate the lack of airflow to the engine bay. Your call!

 

5. If I implemented these changes, would |I need to look at strengthening the bottom / top end of the engine or would it cope?

 

No, as long as you don't go past 1.1/1.15BAR of boost pressure. You will be wanting a metal head gasket from a rev3+ as well though.

 

On the subject of downpipes, make sure you get one with a flexi in. The transverse mounting of the engine in the MR2 lends itself to flex and a solid downpipe WILL crack. Repeatedly.
