Quote from: threepot on June 23, 2022, 21:26Fitted some engine mount inserts tonight, and some brooks shifter linkage bushes.




But on taking the engine mounts off, look at the state of the top bolt in the front engine mount  :o


Whoever put the engine in this car needs taking off the tools ASAP. Are they having a few cans on the job?  :-\  Everything I look at is a bit half arsed or buggered up.

Luckily a quality tap sorted the thread out and all came good.

Tomorrow I get to collect the freshly painted hard top and bonnet, can't wait to see the car all the same colour.


Welcome to the world of modified 2s.
Most are bodge jobs.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

It's the price point of the cars, they were sub £1000 car. Just mix one up with a £500 corolla and you get something magic.

At this money no one is willing to spend £2000 on labour to do a decent engine swap and tinker job. Instead end up being done by some dreamer and his mate on their drive with limited resource, skill and experience.

Saw some garage guy on youtube offering 7 hour 2ZZ conversion, drive in and out in a day. £600 labour think they said in the comments, might have been in Northern Ireland. You're not getting attention to detail in that scenario.

But now somehow MR2's are getting a bit more attention and even ratty ones are going for £2000. I've not been able to buy a worthy 2zz Corolla or Celica for sub £1500 for the last 18 month - I've been looking pretty hard - thus why I bought project horrific.

I think there might be a story to this car... the cage, the fire system, the lightened doors.... I think someone had this work done to run in the MR2 championship. Then lost interest and sold it to someone else, who put the 2zz engine into it badly.

2 became 1 starter motor is fitted, and tried a few times at temperature. All seems OK so far but time will tell.

Fitted an OEM foot rest earlier as I find it important for driving position and cornering, had to bond it in as one fixing had been cut off the bodyshell and I wanted it stable with no rattles


Then... the most elaborate oil change I've ever done to date on any car  :o

The level on the dipstick has always been way over the metal bit and onto the flexy cable since it was bought. Thus drained oil into a fully washed out to nearly new drain tray, and weighed to figure out quantity. This drain out fluid STINKS of petrol, but that fits as it was running insanely rich and stinky due to all the exhaust leaks and vacuum leaks etc. I would speculate that running on such badly petrol diluted oil might have caused the excessive cam wear. This oil was 60g per litre lighter than the new oil, so it might be 20% diluted with petrol at a wild guess??!


Then, on inspection the dip stick has had a bit of pipe added too it, so it doesn't bottom out in the tube correctly. Some has done this on purpose to make the target oil fill level higher.

So I did some quantification of the Millers CFS 5w40 NT+ oil.... I get it 860g per Litre, and the empty bottle has a tare weight of 232g.



From the toyota service manual it states 1zz-fe as I have that sump fitted :-
QuoteDrain and refill
w/ Oil filter change 3.7 liters  (3.9 US qts, 3.3 Imp. qts)
w/o Oil filter change 3.5 liters (3.7 US qts, 3.1 Imp. qts)
Dry fill 4.2 liters (4.4 US qts, 3.7 Imp. qts)

So I put in the exact weight of oil required for 3.7 Litres and it ended up here on the dipstick... half way bang on.


Added another litre (4.7 litres) and it came nearly to full.... so I chucked the last 300ml into it for a 5 litre fill which is just over the F point. After all this thing is going to get cornered mega hard next week, and compared to the 5.56 litres of petrolly oily rubbish that was in it we can't do more harm.

But there is some variables at play, the front and rear engine mounts have long adjustable holes, you can loosen them and re-seat the engine at maybe 10 degrees difference in pitch? Any thoughts?

Quick 2 hour stint trying to finish off the jobs list.

Put the stainless braided hoses on all round, one of the original ones was split to bits on the front.

Pedal feels amazing now.

Then put the refurbed wheels with the AR-1 Semi slick on too... took it for a quick blast round the block - OMFG!!! They are mega sticky tyres. You can brake so hard my fillings might go though the windscreen  :o  and they were barely warm. I'm itching for the track day next week.

Feel free to replace the drilled discs with blanks. Drilled just end up cracking between the holes with the heat, and aren't really needed.

I found they made more noise and dust.

Depends on the quality of the disc, surely? Been around M cars a lot over my life and the quality drilled discs only start to crack when they get quite worn - cheaper replacements start going far, far, far sooner.

Tarox - Sport Japans were my go-to road disc (when I liked fast road cars) never had any issues with cracking on the 370Z and a 500bhp M135i I ran them on.

Personally would always go grooved on a track car, but a world of difference between discs costing £50, £100, £300, etc.

As for the AR1 - I've found that the fastest track tyre (that's still road legal) on the MR2. Closely followed by the A052. You see mixed reviews of the AR1, but mostly heavier cars or people running far to high a pressure. Set them about 24psi cold on the MR2 and you'll not be far wrong. The AR1 is especially useless tyre in if track has anything more than patchy damp patches - they drop off quickly if they lose heat (which is maybe why I'd use A052's unless chasing lap times - work well in the damp and less thermally sensitive)

SuperArt

Strewth, never ending the amount of botch-work you're discovering.
Still, one way to look at it is you're finding out about these issues while you're not in the car. I'd hate to find out on a track day, would be too late then.

I concur with earlier comments, never seen a single modified two that hasn't been bodged, such is the nature of a cheap car nobody spends the dough doing jobs correctly.

Any drilled disc for the MR2 is going to be aftermarket, and not OEM. These WILL crack with hard enough use.

Horses for courses, but the MR2 simply does not need anything 'better' than plain OEM discs in track.

Last few jobs today on the car, check gearbox oil, fit induction kit with new MAF, general once over.

On top of the jobs list for the car, there was also the jobs list for the trailer...

New set brake shoes
New set brake cables
New set of wheels + tyres
Dropper plate for the hitch on the rav4 so it sits right
New rear lights and proper wiring job
Some welding and fabrication to the ramp storage to make it decent
Straps shortened etc to make strapping it down straight forwards

Just been out for a test drive about to make sure all the trailer brakes are working properly and nothing is going to fall off.

While I inspected everything on B&Q car park, I had to take this photo with the sunset clear blue sky.....

Ready for this weeks 1st track day - if I bin this car on its first outing it'll take a while to get over it  ::)

Who says lightning can't strike twice in the same spot?

Project Horrific strikes again !!!!

On the sighting laps this morning I noticed a very loud knocking rattle.

On inspection turns out the fuel tank was held in with 3 bolts = 1 missing, all 3 remaining bolts were finger tight and one was only in by a couple of threads. That could have been very dangerous indeed, deadly even.

I really am starting to think very little of the cars previous keepers indeed.

And lastly, at 2:30pm as the weather was getting better, track dried out and warmed up in the sun, laps started to really get on the gogo......

....... the clutch gave up the ghost. Can't select gears as the pedal won't push the pressure plate fingers. Had to get some guys to help me push it back on the trailer.

::)  :'(

I'm guessing you did you not have the fuel tank out to replace the linkages?

threepot

Didn't touch the tank, just lubed up the stuck brake cable from both ends. And the bushes were done just in situe.

I think someone might have started to do the brake cables, but then quit after a few bolts. Thus the new cables included with the car. Seems like lots of half started half finished stuff on this.

I've ordered a new clutch and light weight flywheel for it last night. And I have this brand new old stock gearbox in my shed to use too. So that will whisk a few nights away doing a tidy job of that.

On a positive note while the car was working, I think I might have been one of the quickest lappers out there. On those warmed up semi slick AR-1 tyres and current suspension components it has more grip than I have ability and balls!

And I didn't really get into it fully with the short amount of working time. Some douche in a MK1 MR2 leaked oil all the way round the track so play time stopped for almost an hour. Plus a bit of rain in the morning too. Didn't get much party time before the clutch stopped play. The MK1 looked pretty rough race car type affair, I didn't talk to them though before he left.

I thought I had read you had replaced the linkages, but it was just the bushes.

I don't understand why you'd only put 3 bolts in a fuel tank, it's not even as if they are hard to access (like the engine mount bolt)

Rough luck with the clutch.

I completely agree that the workmanship on the build is extremely shoddy based on all the things that you've found but that's not the fault of the people that have owned the car (you can clearly see that the car has been used very little since the 2zz conversion and track build) - that's down to the person that did the work (which was neither of the last two owners!)

JB21

Seems this is a mix of shoddy workmanship and just plain bad luck. You'll get there mate.

Thought Rogue Motorsport were at bit shoddy in my build but reading some 2zz builds on here and Spyder chat its not really. Just stupid small overlooked things on mine that caused me real pain. Like not spacing the dipstick correctly leading to engine failure, and using a 1zz clutch plate leading to clutch failure. The rest of the build is spot on TBF, and looks like now I have rectified these issues I have a quality build.

You would expect better from Rogue as they have completed many 2zz swaps and they do charge accordingly!
I guess it can happen with any engine swap and once those bits are sorted you both will have the car exactly how you want.

So was the engine put in by Megillian Motorsport ?

Yes; the whole build was.

JB21

Don't even get me started on Megillian, guy is a whopper! Paid for a half cage back when I first got my 2 and he just totally blanked me once he had received payment. Took months to claim my money back. He done this to a few people at the time. Sure he still trades as well.

@threepot

Man your having a time with it >:(

After 3 years of ownership, I have mine handling and feeling pretty good (imo), having done a couple of trackdays i'm more than happy with the feel of the car and the confidence in the bends, being a bog standard 1ZZ it gets hammered on the straights, ok frustrating, I have contemplated going down the 2zz route but hearing and reading some experiences, think I'll stick with me slow old girl
