Project Smurfette GTR build

Well it's a big moment in a life of a boy. Deposit paid and date booked in. My R32 is finally going to get a proper build. After reading many threads and posting a couple my self, the plane is just about set.

the engine will stay a 2.6L but the compression will go up to 9:1 (to help low end but still allowing me to run 98ron as a daily driver)

Mahle rods (it's amazing how many rods are made in China and re-stamped as something else)

wiseco psitons (come with a nice anti friction coating)

Cams will stay around 260/10.8mm mark (depending on the final choice of turbo)

will go to a single precision cea gen 2 turbo either the 6266 or the 6466 (still researching dyno graphs. Would love to have a streetable 700hp)

after doing as much ready on the borgwarner turbos as I could find, I decided not to go that rout. It is indeed a top end product but the titanium technology is not yet proven and if these turbos cost a fortune to repair. Plus there are more and more threads about both water and oil versions leaking. With precision being air cooled, that's not an issue. As for Garrett, well they are just not quite there yet with their technology. I want to stress that this is only my opinion and I am sure it will differ from person to person.

walbro pump 

1300cc injectors

oil 

and all the supporting little bits and pieces and machinery included.

car already has a twin plate clutch, adjustable cam gears, power fc d-jetro, trust drag intercooler, super stiff coilovers all around, bolt in rollcage. Currently a kitty has been started for an R34 6 speed box conversion. Hopefully I can through that in as the car is being finished of.

currently the car runs a light blue paint which is identical to a Smurf. Hence Smurfette. All the spoilers will be removed and paint smoothed out and fixed up. I already have a set of very light weight 17/10 wheels but might see if a I can the graphite colour redone on them. 

Power Goal is to have around 700awhp on E85 and 600awhp on 98ron. 

Driving goals are to run high 9 at the drags and see how close I can get to a 1 minute lap of the barbagallo long circuit (big ask).

all criticism and suggestions welcome.

will post pics over the weekend.

Well good luck to you.  Nice to see someone from Perth having a go.  You may want to have a look at Antilag as there are a few GT-R's getting built and written about on that site.

Seeing as you asked for criticism I would point to the following as questionable:

power fc d-jetro, trust drag intercooler, super stiff coilovers all around, bolt in rollcage. Currently a kitty has been started for an R34 6 speed box conversion.

Also if you want a 60 second lap at Wanneroo you will need brakes which probably wont be compatible with 17" rims.

I am looking into brakes. There are some good upgrades available but the time aim getting close to a minute lap time, I re Kon it will be time for digger callipers and wheels. Good call

By the time you are getting to 65 second lap times you will be hating on Sumitomo.  Trust me.

Photos as promised. She is looking rather sad after almost 4 years of storage. Found an old dynograph. Good news is oil is still see through and no water in it. Boost gauge will need an upgrade, only goes to 20psi. a902734b48d6f47a9f36000f52c2129e.jpgf68a6cd867014ca6129c45ae5c0f34c1.jpg0cb8e021fa0f070755d6db2ed0e2db20.jpgf6744db14ed65e281ea473a3fe573f56.jpgf075ee6367569cce3e4a64d0b13d2d3a.jpgf535079acfd7b53c0bc089e405b0234a.jpg

Well it's been a few months since any updates. Allot has happened. Almost sold the car due to a health scare but luckily all is well. A few cheap parts have jumped out and changed my plans.

So now I'm going with an RB 26/30 combo.

Have a block
Rods
9-1 Pistons
Bearings

GTX4294 twin scroll turbo
Twin gates and manifold

Should make for a nice 800hp at the wheels combo on e85

  • 4 weeks later...

Well it's been another long break since the last update. Nothing brightens up a day like a box full of engine goodies. Once again, huge thank you to GhostK for his help with parts.

Rods
Pistons
Rings
Bearings
Belt
Tensioned
Water pump

Tomorrow I hope to get the huge turbo kit GTX4294R
Gates
Manifold
Dump
Screamers
2000id injectors
Fuel pumps
Fuel rail
Surge tank
I think that's it

Already have the RB30 bottom end with the 4WD sump adaptor

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
