Re: Ok plan R

oops my bad, missed this thread lol

Reports back and its a bit of a mixed bag, nothing has failed parsay, but the bearings are worn to copper (all of them), valves are worn, crank is marked but looks like it will polish out. Biggest problem is the block has a taper on it thats way out of tolerance, 3 thou on 1 and 3.

Cheapest options would be to machine the block, put oversized pistons in and refresh the heads. Problem is that will thin the walls of the block and limit it to about 350bhp without risking it self destructing. Thinking was to 2.1 stroke it, but given the power limitations there would be little point.

But there is a silver lining

I managed to source a 2.0 closed deck block for decent money, all machined, rear thrust mod done and only needs honing for the pistons. Adding the 2.1 stroker and refresh my heads and reassemble.

With right turbo and supporting mods will easily do 500+

Only slight hicup is the engine build shop at clinic is mega busy, so gonna be 4 weeks till they can even start it .

But all good things come to those who wait

Not sure how you come about that, I know you have a vendetta against them, but lets not start that argument again.

No vendetta by just reading your thread, but if a garage I had used for years and spent many thousands of pounds at did the same to me Id be looking for another "Specialist",
How many other Health checks are as good as this one ,
Nothing personal about people charging for something then a engine is fubard a few short weeks later, after being told x or y was wrong and charging you for bits, then POP!
Not a great service is it ?
Maybe Pat`s hearing is starting to go if he didn't hear the state of your engine, or just didn't use det cans or they know your a sucker and would just pay up anyway,

The BMW was best thing since sliced bread when you got that, but that didn't last either,

How can you still tell people they are the best blah blah blah when you have just experienced this ?

I don't think that's being personal, it is just based on the fact you have given.

Re: Ok plan R

Not sure where your coming from,

round of mods were done all good except the turbo was showing signs of age and didn't run good power.

2 months later I decided to replace the turbo and it went in for new turbo and remap. They moved it into the workshop to lock up the day i dropped it off and mechanic noticed a slight rattle on start up. Before they started changing the turbo they gave it a check over to try to find what the issue was, they found at roughly 2k you could hear the rattle.

I was advised of what they had found and i agreed to have the engine stripped down and assessed.

When it was stripped they found bearing wear, block taper, valve wear and light marks on the crank, this proved the diagnosis of the rattle to be correct.

Are you trying to claim they have blown it up?

Re: Ok plan R

And as far as the M3 goes, it was a really nice car. Just didn't do it for me as a weekend toy.

Re: Ok plan R

Just realised i didnt ever update this thread

So, engine was stripped and found to have a pretty big list of faults, crank bearings were worn down to copper, block had taper on the bore, valves were worn etc etc.

Decided in the end to get a 2.5 dropped in it, of the closed deck converted variety Heads were rebuilt with supertech valve kit, and everything replaced (only original part of old engine is the head castings )

Some of the damage,



New vs old bearing (new still has protective coating on it)



one of the fried valves,




So seasoned block was sent off for closed decking and came back, comparison of closed and standard 2.5 block.



So nice pile of parts



Short block sorted,



heads assembled,



attached to short engine,



and then back in car and round to load of the dyno for running in map



Did the 1000 miles and then back for mapping

Re: Ok plan R

Found out during running in the turbo was on its way out and the oil seals leaking so ended up with a custom billet GT2871r that had been sent for testing.

Turbo was put on and car loaded onto the dyno for mapping. First issue was found with the fuelling and not being enough. So 740cc nismo injectors were fitted, fuel pressure reg and larger fuel pump.

A new age sti top mount was also added and the final results came in,



330bhp, 380 ftlb

They stopped mapping at point because the torque had climbed so much the gearbox was at risk.

With the short ratio box and light weight it went really well.

Rough final build spec,

2.5 closed deck block
nitride crank
mahle powerpack pistons
Manley rods
ACL bearings
ARP had studs
Supertech valve kit
rebuilt v5 heads
GT2871r billet turbo
740cc nismo injectors
perrin 4 bar map sensor
perrin intake pipe
perrin fuel pressure reg
New age Sti top mount
GFB dump valve
Syvecs ECU
GT spec gen 2 headers
Harvey smith up pipe
Full cobra decat
perrin oil cooler

and a whole heap of other ancillary's that were nackered.

Re: Ok plan R

The 330 lasted about 9 months before next round happened haha

Dropped the car back off for the next round of mods and had a slight wait of about a month. Parts were on back order

But they finaly arrived



yep two small shafts held it up but they are important because they convert classic female drive shafts into male to allow them to fit a hawkeye sti 6 speed box

A nice stealth one of these,



yes its as big as it looks lol



Perrin induction kit and also a competition clutch twin plate and then back onto the dyno for mapping, again hahaha



and the result,,,,,



398.2bhp (dam that 1.8 lol) and 465ftlb

Needless to say it pulls like a train, although turbo is giving everything so it runs out at the top end a bit, still fun to drive and chatters like a an eskimo's knees haha
