My 1995 GTR project thread.

John maybe i should rephrase that as 10k safety net for when i over rev past 8k in first and second gear I dont intend to sit in the 8k-10k rev band all day

[gtrjon]

10k rev limit eh. with pon cams?

SO small update to my plans more than anything else .

I've spent a majority of winter researching as much as i could on the RB , tuning , power , response builds etc and this has caused a slight change in direction .

Original plan was to tune with a power fc ljetro and obtain some nismo mafs as i have the greddy suction kit installed but decided against this and will be installing a Vipec V44 ecu and ditching the mafs and O2 sensors.

I did a compression test tonight after a quick blast aorund the block to warm up the engine and i have 158psi - 166psi across the board except cylinder 5 which is puffing at around 140 psi. This is outside of the factory tolerances and although the car pulls and runs strong , it suggests that increasing its power output at this stage is probably a bad idea.

I have a titanium tomei exhaust coming soon that will be installed this spring to replace the trust system that is on there at the moment. But the main decision has been to build a longblock to replace my present block. I'll also install the vipec system and get used to using the tuning software on the presently installed engine, and if the learning curve blows up my present engine it wont be a total heart breaker

I really didnt want to rip the existing engine apart and have it off the road for a year so i have elected to start collecting the parts i want for a blueprinted lightweight and strong block assembly .

I have got a brand new r34 crank on the way as well as a set of Forged carillo H beam rods and CARR bolts , looking at a set of mahle pistons to complete a very strong and lightweight internal build . Add to that a pair of Tial BOV's to replace my suspected leaking factory units. Looking for 10,000 rpm rev limit . The Tial BOVs are VTA which should be good with the mafless vipc setup and will enable me to ditch all the BOV return crap and pipes.

Need to obtain a block and head from somewhere , I have a new set of HKS valve springs , poncam b's , nismo intake , hks 680cc injectors amongst other parts ready for the new build .

Im going to stick with stock valves in the head but after some research im going to port match the head to the headers and throttle bodies . I have a seal kit for the ITB assembly to make sure it doesnt leak . go ARP fasteners for everything (except the carr bolts) and a cosworth head gasket of .8mm but going to have the head shaved very slightly to increase compression by a small amount to help enhance the response.

Main challenge is going to be finding a machinist familiar with the rb26 that can machine it properly and not screw it up . I called a few places this week and 2 of them dont even know what an RB26 is. Suggestions would be most welcome here.

Trying to figure out what to use for a block , was thinking of sourcing a brand new 24U casting but they are far and few between and rediculous pricing also - not sure if my build , power potential really requires it. A used head from a running R33 engine would be a good starting point , i'll be rebuilding this myself .

SO thats the plan - more will be added once Daryl has my new exhaust and I doc the install with pics of course

The turbos are great , im in a state of parts collection atm , will be ading lots of updates this year ....

[GT-RJules]

what happened here, i want more of this beautiful build. any qualms with the tomei turbos?

Sorry missed this reply ....

The Hids i have are 9000k , a bit on the blue side but they light the road up very well at night in my rural area.

I have been flashed maybe twice in 12 months since i did the conversion ( about 6000klm) .

Good to know, I think I will go with 6000k then, they should give me good visibility without being to bright. Thanks!

What color temp HID's did you get? I am looking to get some to as the stock one's are not very bright. From what I have read there will be a serious amount of glare for oncoming traffic. Have you had any trouble with this since you installed them?

Here's the kit I am looking at, http://www.vvme.com/hid-headlights/s...conversion-kit

^ i mean R33..lol

correct

[trickey1991]

fu ck this guy .. lol jk man this thread rocks..i just spent 1.5hrs reading if from page 1.. wow time flew by..anyways..now u know what i do at work everyone..lol anyways sick build

^ i mean R33..lol

but your can does pull it off super dope!

[frankiman]

Just saw your update, glad that the diffuser work out for you! I think you are only one with it in Canada..lol

not!

I'll tell you a short story of my youth many moons ago...

When i was 17 and drove a 3 wheeled bon bug (if you want to know what that is , google it), i blew the head gasket.

After waiting for 2 months for my dad to do the work and fix it , he told me to start work on it and he'd come along and finish it.

So i started stripping parts of the engine , manifolds , carb , headbolts etc etc and because he actually didnt come to help , i ended up stripping the whole thing myself.

Removeing the head was a pain, one of the studs stripped the thread in the block and i had to have the head skimmed. The engineering firm also leant me a tap and die set to recut the thread in the block , and machined me a new stud for it . After a few more weeks I reassembled the whole thing with the help of a haynes manual , had the thing running and driving.

No help from my dad. I bitched at him for not helping me and he told me .....

"if i do everything for you , you'll never learn how to do anything yourself . By doing it yourself , you learn how it works , you save money and you experience a sense of accomplishment when it starts and runs"

Ive pretty much applied that theory to most of my life including the running of the business i currently own!

Best advice he gave me .

ur definitely right if u dont try things, ull never learn to apply it, Thanks for ur advice and i hope to make an inspiring build thread like this one with my future R33 V-Spec (currently have a commuting car 2011 Jetta) its definitely no GTR but my parents want to keep my racing habits down (i race go karts) and teach me to be mature, as owning a GTR is a big responsibility (no sarcasm :P ). Thanks and keep this anxious community posted as we r dying to here what u do next!
Thanks for the reply, by the way my name's Alex

Took almost 2 hours to read, but finally reached the end...of what will soon be more knowledge to retain :P Great job and keep up the great work! Any advice for someone not so handy under the hood? Because ur right, the satisfaction of doing projects ur self is as the french say "Tres Magnifique" :P
