Ok...this is goin to be a long post as i dont want to post several little ones :P .

I have a r32 skyline with a rb20DET. I'm wanting a powerful car but i dont want to loose the streetablity. My goal is to get in the 10 sec qtrs :P:(

Does the RB20DET have the potential to get there, and how difficult would it be? I've heard that the quickest rb20det powered r32 in aus is a 10sec car. Have i been misinformed?

Would it be worth my time / money try the RB30 Block / RB25 head conversion into the r32 or just play with the RB20DET motor...keeping in mind i'm wanting to eventually run 10's.

What would be the most cost effecient proccess of going about this.

All input would be appreciated as ive been wondering about this for ages and just curios as to what other people think about it.

Cheers

sLo :D

its achiveable but you would have little or no driveabiliity what you need is a package like this.

see below.

the rb 26 is the most cost effective way to get your car into the tens and yes it will cost quite a bit

but its doable

It would be alot easier to go the proven method of suing a 3 Litre bottom end and twin cam head. Don't bother with the RB20 Head go straight for an RB25DET head and this will easily make you get into the ten's with a total standard head and standard bottom end with forgires and balancing. If you need proof VORT N the skyline ran a 10.6 with this setup with just a big turbo, fuel system and other boltons eg. Cooler, plenum.

meggala,

"the rb 26 is the most cost effective way to get your car into the tens and yes it will cost quite a bit but its doable"

RB26 and cost-effective don't go together. you'll be looking at $4-5k alone just to get a long motor plus anything else you would want to do to the engine along with bolt-ons.

slo-32,

the RB20DET is a very good engine when it comes to strength and durability although it wouldn't be the best alternative if you want a streetable '10sec R32' as they aren't the torquiest of engines.

you would be much better off if you went for an RB30/25DET hybrid, it would be a larger capacity engine which will give heaps more usable torque and power, which is perfect for a street car.

Also, it'll cost you less than sourcing a RB26DETT engine along with the associated work fo sprucing itup for 10's.

good luck.

well most rb 25/30's I have heard of that could run into the 10's are 15-20 for the whole setup with the rb 26 for that kind of money you can make 700 hp with out a problem you have a motor that is designed to run that sort of out put and has a lot of little things the rb 25/30 doesnt.

this is some thing I have given a lot of thought to If you can show me a complete package rb 25.30 built that will make 700 hp for under that I"m all ears and yes I'm including engine managent turbo's injectors etc I havent even started on the drive train yet iether but of couse RS500 your talking about a slopomatic as well not a manual :P

didnt sub zero get 2 r 33's with rb 25's in to the ten's the 25/30 has its point but I agree to disagree with you re their suitability for this application

Well all I can say if from what Ive seen is that if VORT N setup ran a 10.6 in an R33 with wheelspin then this should get close to a 10.0 or even 9 in a well setup R32. He is currently selling his setup if you are keen i can ask how much he wants but it is now been rebuilt with ARGO rods and all the rest. It will do a 9 sex pass easy

meggala,

you yourself know that even the RB30ET itself (without the RB25 head) is capable of producing up to 700hp which has been proven by many workshops who are pushing up to and over 400rwkw along with 9-10 sec 1/4 mile times.

Given the advantage of the increased flow of the RB25 head over the SOHC RB30 item, it would be safe to say that it would 'comfortably' make the 700hp with less stress than the RB30ET engine.

My point is that by starting off with a price tag of $4-5k just for sourcing the RB26DETT without even opening it up to strengthen it with forged pistons, etc already extends the budget to your quoted $20k, whereas, ~350rwkw can be produced with the standard spec RB30ET bottom end (with de-comp plate : proof - my friend's engine which has also run a 10.7 with standard EC and micro-fueller) for a much less price tag including a programmable ECU.

how do u figure that a 700hp RB30/25DET engine will cost the same ($15-20k) as a 700hp RB26DETT?

I'm pretty sure the RB26DETT package will cost much more than an RB30/25DET package when starting from scratch (i.e., forged build, including turbo, ECU, manifolds, etc, etc).

the difference in price would be the price you pay to buy the RB26DETT engine in the first place, where the rest of the mods will be the same for both engines.

that's my opinon anyway.

the RB30/25DET conversion would be the most cost effective as no mods are required to fit it in the engine bay.

It will sit onto the factory RB20 engine mounts and it will bolt straight-up to the RB20 gearbox, so i think this is your best option if u want to look at sticking to a budget, otherwise if u have the $$$ to spend, the 2JZ-GTE is a very very nice option.

You want 10sec on a rb20 gearbox? Good luck to you sir!

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.

      The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
