Piglet's Rebuild Of His Busted Tomei 2.8

[Piggaz]

Specs can't be released until we know the results. I don't exactly know what they are.

PS Your turbo arrived today. It will be sent off tomorrow.

[Piggaz]

Just got home from Harris and bit of progress today.

Cams are in without the need for a tunnel bore. Thank god. After 6 hours of messing around with caps the cams turn like a mofo. More work done to the accept an even larger cam if we decide to play around in the future. Relieved for upto 11.5 mm using a 32 mm base circle.

Crank got balanced which was something that Mik didn't do back in 2005 when it first went together. The pictures show how far it was out from Tomei.

Block about to accept it's insides.

Girdle just chilling.

Tomorrow when my main studs arrive it will be dummied up. Might have to take a bee's dick off the top of the block to get to 9.0:1.

[Piggaz]

6466 arrived. Good thing Steveo labeled it. Definitely know its mine!

[R32 TT]

ah yeah right cause it says 2.8 on it... making you somewhat different to all the other fags having their motor built there..

[33GTRV]

LOL! Good to see some 3L vs. 2.8 rivalry there! Crank was unusually out of balance? mine was near spot on. Only took a tiny bit out. Either way, good too see some progression mate

[Piggaz]

I don't know HOW far it was out... but two holes that deep is't .4 of a gram.

[zebra]

Was it balanced with rods/piston weight?

It's not that far out really, and considering tomei would machine them with their own pistons and rods in mind

[Piggaz]

rods and pistons haven't been done yet.

[zebra]

...better hope you don't need to put any weight back in haha

Can't see the pistons and rods being different weights over the set of 6 though

[33GTRV]

not a wieght thats negligible anyway. I had a set of spool rods and a set of custom CP's and rings all wiegh up to within 0.1 of a gram. The manufacturing tech used these days is heaps better than days of old. Well, unless you are buying 1900 dollar stroker kits for 308's Im building one at the moment and its giving me a headache! Told the guy what to buy, he seen the el'cheapo kit and thought it'd be the same as a set of carillo's, KB pistons and a Billet crank for less than half the price lol.

[zebra]

haha ouch but...care to pm me which kit that was?

[Marko R1]

A very well known engine builder was telling me about the tomei kits he has worked with and they have always required some 'tinkering' to get them right on terms of balancing and tolerance setting. No big deal IMO, as long as your engine builder can recognise this need.

[GTRsean]

Hope it is grubscrewed too. Easier to clean crank oil feeds.

And use some gloves with those L19 rod bolts!

[fatz]

this thing should chirp second*

Good to see this finally coming together !

Paul I've flicked you pm with details of that graph and specs.

[Piggaz]

Nothing arrived yet Marcus.

EDIT: What a little weapon

[33GTRV]

^{Do Share!}

[elrodeo666]

Nothing arrived yet Marcus.

EDIT: What a little weapon

Yeah not bad for something built over 15 years ago.

[Piggaz]

HUUUGE update.

Everything is bolted up, torqued down. Thats it, it's all done!

Nitty gritty details of the engine are as follows;

Piston to bore clearence is 2 thou

6 thou deck height with a 35 thou thick (0.9mm) gives a squish of 29 thou (Bobby. A bit tighter than what you said but its close enough)

Comp ratio is smack on 9.0:1

CC of the head is 66 CC

Piston CC is - 12.2 CC

Top ring gap is: 16 thou

Second ring gap is: 18 thou

Mains clearance is: 2.1 thou

Big ends is: 1.88 thou

That little prick the bolt fairy has moved some bolts and nuts!!! . Sump to bolt nuts and bolts, oil pump, water pump bolts are MIA! Ordered them all from Nissan on Wednesday and luckily most are in the country. Pick up on Monday morning.

[Piggaz]

Also picked up my Nismo intake plenum, AFM delete pipes and my surge tank today. I had them sprayed black because I wanted it to took "stock". Well that sorta changed with the single idea .
