Approved.

How do you find the PAR box?

This car is still 'in-the-build' but will be fully running for Powerplay next weekend.

He actually purchased the PAR gearbox off me, I had it behind one of my cars (my 535rwhp R32) and it was awesome!! I'm sure Jay will love it (especially the noise!)

thread is approved!!!!

the engine was just being finished being put together this afternoon by the boys at Mercury Motorsport and its being put into the car with the PAR gearbox tonight.

here is some info on the engine

Engine– MERCURY MOTORSPORT'S CUSTOM DESIGN RB26/30

RB30/26 "3064cc"

Nitto oil pump

Custom crank girdle

Chromemoly main caps

CP Pistons

SPOOL Rods

ARP main studs

ARP head Studs

Modified bearing caps

Lightened and balanced crank

Ported head

+1mm oversize valves

270/270 camshafts

valve springs & titanium retainers

Oil Cooler

ATI 1000hp harmonic balancer

S13 Power Steering pump

Nismo engine mounts

PWR oil cooler

PWR power steering cooler

Koyo radiator

here are some of the engine components and assembly photos.

If your wondering what the hell the 1st photo is the custom crank girdle, it ties in with the chromemoly main caps. Its purpose is to keep the engine tied all together and to stay true at high rpm and horse power.

And the last photo is of the chromemoly main caps that tie in with the custom crank girdle!

Stock crank? Maybe I missed it, turbo?

sorry mate, i was just planning to do a post a day up in each area on the car with clear photos, so its easy to follow the build. As there is a fair bit going into it.

tomorrow ill post photos of the engine with all the bolt ons on.

but feel free to PM me or missr32 for any info if your really curious.

keen to hear about how good the gearbox is because everyone seems to bad mouth the PAR sets

To be fair, comments like that are why there's a bit of doubt about them :D

The SR guys have the issues, but they've been swapping to rb25 boxes as the SR boxes just aren't as strong

I know! But, this box was behind my 535rwhp RB25 and it was fine. It's had a few hard launches at Willowbank as well and never missed a beat, always shifted smoothly. For me, it was fantastic.

In saying that I've also had a PPG dogbox behind my 25 as well - it was awesome (clutchless shifts ftw!) but was a bitch to drive on the streets. As the PAR box was synchro'd with a shortshift kit, I still had to use the clutch so the gearchanges weren't as quick as the PPG but it's such a smooth box and so nice to use on the street.

PPG's are only quick to shift if they are built right...lol

The engines bolt on's are just as important to match together to work properly as the engine so to achieve my desired response with power i went with

GCG TO4r

6 Boost manifold

50mm Turbosmart Wastegate

Custom 4 inch dump pipe

Hypertune plenum

90mm throttle body

here are some photos

    • BRUH, one of the biggest mistakes of my life..... and i've had plenty ;[)
    • @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.

    • It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!
