Blown A Standard Turbo On Gtr

[R32 TT]

Matt ,

Pete is spot on , i have the evidence still here , the old pistons , the 3 rears stuffed when it spet a turbo in my old 33 about 2 years ago .

Someone took it for a spin around the block and came back with one exhaust wheel in the cat and ceramic dust everywhere in the engine .

I did a complete rebuild on that engine at the time , even the oil pump was scored a little . All  3 rears had low compression around 70-100 psi , 2 valves were slightly bent and ceramic crap imbeded in the cil head , not a pretty sight .

I know of several rb 26's that had the same problem , some with less damage than mine , it probably depends on the revs at the time and if you backed off or not , as i wasn't driving i can't say what revs it popped ( i assume 8000+) and if he backed off straight away or not .

I know SK is a bit skeptical even after i posted pics of the pistons in the forum , but several others have seen it happen .

I hope your engine is fine but if i was you i will be budgeting for a rebuilt .

Mmm.. sounds ugly. So what would you say I'd be looking at budgeting for? Since the pistons, rods and crank are "intact" is is more likely just new rings and bearings? (and perhaps oil pump as you say)

You would need to rebore the block , new o/s pistons + rings , grind the crank ( leanish at the very least )new undersize bearings , maybe new oil pump and thats the bottom and done . Cilinder head it depends on whats wrong with it , maybe just normal service if no bent or burnt valves .

Then the usual gasket set , water pump timing belt , maybe tensioner and iddler and of course some new turbos .

Cost it will depend on parts used at the low end using all stock parts and assuming no damage to the cil head . Trade price from Nissan , pistons and rings around $1200 , bearings aftermarket around $150 for both big ends and mains , gasket set Nissan $300 , oil pump Nissan N1 $500 , water pump R33 $120 R32 $250 ( you should be able to use R33 , slight mod )timing belt Nissan $90 ( $60 aftermarket )tensioner and iddler aftermarket around $100 for both . Turbos depending on what you get , starting from garrett , around $2400 for the pair ( not available for about 6 weeks ) .

Then you have the machining , bore 6 pots $120 minimum , grind crank $150 and servicing the cil head including valve clearence minimum $300 . Of course you will need 5 liters of oil , oil filter and 8 liters of coolant .

While the engine is out you may want to install a new clutch as well , depending on the power you will have , anywhere from $550 ( normal single plate full face ) to $2000 for a Nismo twin ( if you bring it from Japan ).

On top of that you have a profit margin on parts and machining say 15-20% and finaly assembling the engine and r+r from the car . Someone said something like $500 to r+r engine , if you can get it done for that its dirt cheap , it should be more like $1200-1500 for that .

Thats the cheap version , if you want to spend more money you can always do so by sourcing some better parts or building a stronger engine with forged pistons , rods , crank, cams, etc .

Do a compression test before you remove the engine of the car and then you will know whats wrong with it .

Good luck with whatever you deside to do and let us know whats wrong with it when you pull it appart.
