My car is booked into the tuners on the 7th April to have new turbos fitted and a re-map.

Thing is, I just did a compression test.

Here are the results(taken from cold):
Cyl 1 - 167 psi (11.5 bar)
Cyl 2 - 80 psi (5.5 bar); i dropped a little oil in the chamber and managed 8 bar (116 psi)
Cyl 3 - 148 psi (10.2 bar)
Cyl 4 - 185 psi (12.75 bar )
Cyl 5 - 130 psi (9 bar)
Cyl 6 - 162 psi (11.1 bar )

Treat cylinder 1 as the front cylinder (I may have them in the wrong order).

So apart from them being all over the shop, cylinder 2 is quite low, as well as cylinder 5.

A bit of history surrounding the engine. The engine was running fine until I detected a whiff of oil. After removing the turbo piping, it was clear there was plenty of oil in the inlet side of the turbos as well as inside the mushroom filters, down in the re-circ tubing etc. etc.

Thinking this was the seals on the turbo - I then replaced the r33 standards (incidentally with no play) for r34 standards.

During my test drive, over-boosting the ceramics, I shattered the exhaust turbines on the r34 turbos. I am almost certain I kept my foot down at the time they went.

I need to really get an idea of which way to go now as the car is booked in for this turbo swap.

I am starting to wonder if the oil present from around the turbos was in fact due to Cylinder number 2 and not leaking seals on the turbos.

Right then, just been on the phone to the tuners.

They wrekon a re-bore and and replacement of piston is going to be in excess of £3500 uke:

Help.

 

[TheD]

I'm either now going to put the car up for sale as is or break it. Just can't throw any more cash at it.

 

[gtr-loz]

just buy a second hand engine off ebay for a couple of grand as long as its good!

I can supply a long or short engine, or buy your car mate:thumbsup:

 

[carswaps]

Do another compression test (warm)....unplug the front cas sensor so its not firing fuel into the bores.
post the results again mate.

For a start, someone needs to find out exactly what is wrong with it, how do you know it needs a rebore ?
It alarms me when people pick numbers out of the sky, is that drive in drive out repaired ?

why cant you just fit one new second hand standard piston and re ring it ?
there must be heaps of standard pistons lying around from all the failed engine rebuilds going on where guys need to overbore and fit forged pistons ....

3500 pound sound like silly money to me ....
whats the average workshop rate x 8 to remove + x 4 to disassemble + hone wash hot tank reassemble + 8 + 8 to refit + parts

Numbers aren't picked out of a hat Glen, please try and be helpful.

I'll try a compression test warm.

 

[R32 Combat]

Some places charge £100/hour. You do the math.

 

[RSVFOUR]

As long as you did the test the same for all cylinders I dont think another test is needed .
The compression results for cylinder two are down so much that something is wrong there for sure .

This needs to be looked at in more depth which will cost money as it sounds like this is beyond your capabilities ( beyond mine as well)
The £3500 needs to be explained - whats it for exactly ?

Engine rebuild is not a quick job . Engine out and back and at the same time it would be crazy not to check the rest out ( all your other cylinders are not spot on ).

Its probably cheaper to get a decent engine and swop it over but not by a lot if a garage is doing all the work . At least you then have an engine - the head is worth a fair bit if its 100%.

 

[TheD]

Just checked number 2 cylinder warm, as expected, compression is down further. I was told that would be the case by my tuner.


Costs are:
Removal, Strip, Check block, check head, send away block for machining, new pistons and parts, rebuild engine, refit engine and test.

Thats just based on the block needing work. The head and valves might me damaged.

The fact remains, we won't know the extent of the damage until the engine is out and apart. I can't afford to buy a re-conditioned lump, and the risk frankly isn't worth it. I don't want to end up down the road with a lump that has been removed from a car with problems.

It's obvious the compression is all over the place.

I have two tuners in my area, APT and Henstead. Have already spoken to APT and they quoted me the price.

I was .....
Sounds like a rip off to me and also sounds like picking numbers out of a hat ...

$250 p/h to work on cars ... shit , Im amazed there isnt an influx of kiwis to pomland to offset the reverse ...

 

[R32 Combat]

I suspect that there probably are a few New Zealand engine builders in Australia!!

Glen,
If the engine shop were able to do the work in the time you put together up this thread and IF they charged £45 an hour here that alone would be £1260.

The two main specialists within my reach charge way more than that and using someone who has never dealt with a GTR engine is going to take way more time than you have put down. In fact 'hone wash hot tank reassemble' +8 is just picked out of the air Glen.

Glen, you are not helping me or otherwise. Unless you have something to add to this thread which is useful - Can you please stop posting on it - Fella, it's not making me feel any better about the situation.

 

[RSVFOUR]

That figure is not wildly out for that work in the UK and you definately should go to a RB specialist.

And the list includes pretty much what should be done and you are right you dont know what you will find so be prepared to spend more if you decide to rebuild the engine.

All of course IMHO

 

[TheD]

I spoke again with the guys at apt.

They're saying that to remove the current engine and replace with a second hand one, they'll be wanting around £1k

They said they'll want it around a week to do it and the money will depend on what the second hand engine comes with. For example, if it's from a 32 then the diff will need swapping out. Etc etc.

I was under the impression this sort of work can be done quick with the right equipment. I have offer of an engine but need to find put exactly what comes with it. I need to get a decent quote as moneys an issue.

I may have to consider selling the car as is if not.

 

[Simonh]

It is a difficult one for sure.

If you are handy, have friends that are handy (and willing) then a direct engine swap is not massivley difficult.

If you are prepared to do stuff like remove, deliver, collect and refit the engine then you can reduce some of the costs mentioned above by quite a bit.

2 peope can do a engine swap in 6 hours if there slick.

Give me your postcode:thumbsup:

We would charge £646 for a straight swap. If parts need swapping it will not take too much time and the R32 and 33 diff is the same so thats not a problem.

Oil and antifreeze would be a little extra though.
