My 1995 GTR project thread.

Vipec !!!! Your life just got much easier, I'd like to welcome your car to 2012 haha I love my vipec. Seems like they are starting to catch on now. Still a little pricey but worth it in my eyes

I dunno if I'd say 2012 like the ECU of a new GTR but it's a good ecu. If you want the best, Motec #1 or HKS pro which is supposedly top ranked too. Motecs are around $3000 though I think but you can't beat it.

SMALL UPDATE :-

Bought a block form Vlad at PUR automotive and had it tanked , magnafluxed today at Active engines mississauga . BLock is heavily scored in one or more bores which i knew about so we are going with a +40 over bore. Block will be cylinder and line bored tommorrow .

Ordering a set of Forged Mahle pistons for it tommorrow . Already gave the shop a brand new R34 crank which will be checked and gound along with a new set of Carillo H-beam pro rods with CARR bolt . They are going to be heated up and measured , resized etc.

Going with ACL race bearings for mains and rods , ARP studs for mains cradle and im not sure what oil pump yet - possibly a nismo one.

Everything is being balanced and blueprinted to handle 9000+ rpm , all very exciting.

I wanted to build the block myself but given the small cost to resize , assemble , balance and machine everything to be perfect i'm not prepared to compromise the result. I'm sure given their facility , experience and tenacity their work will be better than mine.! I hada tour of the plant - some of the engines they had there were mind blowing .

Oh and i pick up my Vipec tommorrow from daryl at rightdrive

And a bunch more junk from VLad (spare parts , throttle bodies , oil pan etc etc)

[R33-East]

I am interested to see how everything works out, this will be a great reference for me down the road.

Awesome build you have going, keep us posted!

[RABBIT]

Nice progress cant wait to finally seen this purple whale in person.
yay summer!

dude you should have made a want to buy thread !
i have a 26 block (just oil pan to cams= no turbos,intake or accessories) id sell for 500$ =[


and since i have yet to say it in this thread
HALTECH> all.

[cortexx]

I did make a wtb thread a few weeks back :P you didnt see it

Engine wont make it in this year , will build it up for next winter swap

[cortexx]

Time to start posting pics again , this is the block thats going to be used for the forged shortblock build . It's tanked and magg'ed , ready for machineing now .


I discussed the usage of Mahle pistons with the builder and we decided to opt for a set of Wiseco slugs instead due to the machining needed to do to the mahle ones to clear the oil squirters . We agreed that if Mahle supply forged (and reasonably expensive) pistons for the RB they could atleast machine the skirts to clear the squirters . Mahle's fix was to remove the squirters , we both agreed there were certain benefits to leaving them in so Wiseco won the day (only 22 grams difference anyways) .

Also started to discuss the head a bit more , looks like looking at a set of manley or Ferrera inconel valves for the exhaust , the builder suggested ditching the sodium filled valves ( and showed me what they look like when they snap ) . But not much is going to be done other than poncam , cam cap studs , fresh set of HKS springs , manley valves (.5mm bigger than stock) , and a complete blueprint of the entire assembly. He said he will be measuring the whole assembly and machining the valve stems so that all the shims under the buckets will be the same size. Will make shimming the poncams a very simple job..

Still not really sure what oil pump I'm going to use , considering tomei , nismo , nitto or a trust one . I dont want to use a stock or N1 pump with this kind of investment in the rest of the motor..

[frankiman]

will you get a complete port&polish of the head?
and what HKS valve spring will you get? everything will be for 9000rpm?

[cortexx]

I will not be porting the head too much , the head flows incredibly well for a factory setup , infact porting it will decrease response and low to middle end power if done too severely. I'll be port matching the intake assembly to head but wont be removing the hump in the exhaust ports , this leads to a slight decrese in exhaust gas velocity impacting turbo spool , if i was going large single and looking for huge power i would need to open them up . but not for my tomei twins.

I have HKS step 2 springs (single coil design) , the poncams b's are same lift as factory , increased duration on the exhaust mainly to increase exhaust pressure and spool the turbos faster . I just didnt want to use 17 year old springs on a motor that may see over 8000rpm occasionally . I was going to replace with factory springs but the slightly more aggresive rates on the HKS ones will handle the slightly more abrupt profiles of the new cams .

[RABBIT]

Get Reimax gears or an HKS pump.

[DJ]

is mississauga engines doing the motor?
I wouldn't suggest reimax gears , my stock n1 gear had a tighter fit on the collar vs the reimax gear.Although it is made stronger..

Really? thanks for the heads up.

Small update

Mostly parts collections. A few pictures because i know you guys always like pictures

First up is my Vipec ECU that arrived last week , this is whats in the box and i now need to procure a box to mount it in , might actually make one using some acrylic plate we use to make computer cases at work , ill figure that out later ...



Next up is The ATI balancer that i ordered from Summit Racing , ( only $509 atm ) . Its the one rated for 600-1000 hp , I chatted to the guys at ATI and this is the one they recommended for my build. It also came with an underdrive pulley for the waterpump to adjust for alignment for the drive belt. It's already balanced as a unit and although the machineshop said they needed it to balance the crank assembly I don't think they will be able to , have to chat to them tommorrow about it..



ALso from a forum member I grabbed a pair of Brand New 50mm Tial BOV's , these i plan to run vent to atmospherre as my vipec will be running a 3bar MAP sensor allowing me to ditch MAFS , the narrow band o2 sensors and all the recirculation pipes etc. Im going to run the 9lb springs they come with and see how well they work , need to fab some pipework to mount them , i'm favouring the turbo side of the engine to mount atm , i'll have to give that some thought.



So the short block should be in my workshop assembled sans the oilpump next week or so. The final spec for it is r32 block bored out 40+ to 87mm fitted with wiseco forged, coated skirt pistons , Carillo H beam rods with Carillo rod bolts , a balanced R34 crank kept in place by ARP studs along with ACL pro race main and end bearings. Everything is being blueprinted and balanced , should end up with a block capable of withstanding 10,000 rpm when i ram the budgie into first instead of third ( dont even think of telling me you have never done that ) !
