I had a failure on number 5 big end (not alot of fun) ,so i strip down the engine to then find that my bores are 87mm and are badly scored! they will clean up at 88mm (wich will reduce the block strengh and limit horse power) but then the next problem is that i need to find a good set of forged pistons that retain the 8.5:1 commpression ratio. I since then have found out the ARIAS piston do not go out to 88mm. WISCO made a 88mm but reduce the commpression and are of unkown quailty. Can any recconmend what i can do?? thanks :freak:

ive used wiseco in quite a few of my race bike, seeyagtr, im surprised wiseco wont custom build a set for you, and yes i realise owning a GTR sends u broke, i think its merli who summed it up quite well, GTR=Money Pit

I only hear good things about Wiseco, particularly from guys with race bikes as well as race engine builders such as JHH Engineering?! Anyone have other comments on these pistons??

I ran wiseco's in my GTS-t and they handled it just fine. The guy who bought it off me flogged the hell out of it and did a big end as well, piston's where like the day I bought them. same story basically they are a reputable brand with a good product. it's all the same grade aluminium in the end!

was just about to say resleeve bottom end sice only one cylinder should b fine with the heat side of things and strength.tomei and acl pistons do 88 and are the shit also with compresion they can shave head or thin head gasket to keep compression up.

Thanks for all the info!! It would be sweet to get hold of a secondhand block, even out to 87mm ( good bore )would be sweet but my efforts in tying to get hold of one have proved fruitless! To use 88mm pistons and then to shave the block/head would be the go. I also had bad scoring on 2 and 4 bores that might clean up at 87.5 but i am still left with a floged out number 5!!!! I have not ket priced up a full resleve. I can get the JE Forged Pistons for $1600 custom made wich i did not think was too bad,

I have to weight up the best way to go

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
