Hey everyone, just wanted some people feedback on something, i have a rb20, and are undecided on what turbo to get? Thinking either a hks2530, 2535, or a garret 2860, i heard these are pretty much the same type, or i was thinking of getting a rb25 turbo high flowed, im chassing about the 230kw mark but want it to start making boost early, ill have all the supporting mods, just dunno weather the rb25 turbo will be laggy, hears they can be once there highflowed.

If anyone can give me some advice, or if they have done this, much appreciated guys

Cheers

Have you checked out the Hypergear thread? He does highflows and brand new bolt on turbo's, cannot recommend his work enough. If you can get hold of an HKS turbo cheap enough, should get the job done. Just not sure whether or not it will bolt onto your stock exhaust manifold, inlet/outlet pipes, or dump pipe.

Yer i have seen his website amd read a few things on here aswell? Have u used hos stuff before? Have u got a high flowed turbo that he did? Whats it go like? Spool time and stuff? Yer the hks are really hard to find and usually expensive aswell for a 2nd one. Yer the hks are a 6 bolt housing im pretty sure and ive got a after market dump pipe to fit any 6 bolt rear housing turbo anyway just gotta get the turbo!

Yeah i've got one of his ATR43G3's. 375rwhp on 21-20psi. Kicks in at 4200rpm so it is kind of laggy, but only compared to the measly little plastic/ceramic stock turbo :P

If i were after 230rwkw i would be finding a blown rb25 turbo and getting it highflowed, completely bolt-on, and its the cheaper option.

Why would the highflowed rb25 turbo be laggy? Coz stock would start making boost pretty early?

Its a hard decision i dunno what to get the hks are really expensive, and getting a rb25 high flowed is kinda like a new turbo, the main thing i dont want it to be laggy! Does anyone know much about when they say .63 or something? Is that ment to have something to do with the rear housing?

The RB25 housing is already larger, hi-flowing will further increase the size. Hence they are 250-290rwkw in hi-flow form... But they always nose over.

The A/R is just a relative size. It varies depending on the turbo and wheels in question... And how much meat is removed during hi-flowing

JordansR32, I just got one of the Hypergear RB25 hiflows last week. It's good, a brand new CHRA fitted to old housings, so really a new turbo. Not running a huge amount of boost through it as I'm on stock ecu, definitely tons more top end though. Not alot of instant response though IMO. From what I have read the HKS GT-RS and Trust TD05H 18G are great punchy turbos for the low 200kw mark? There's a Trust TD05H 18G bolt-on kit on ebay for sale at moment too for $1500. Or *product plug :)* I have my old R33 stock turbo for sale cheap suitable for rebuild, and also an R34 OP6 if you're chasing a bit more from the highflow.

Yer i think the hks garrett can handle more power and boost, i want to run about 20psi on high boost with a nistune and all the support mods, still tossing up my opions, ill have a look at the dyno results and go from there i think

Get the Hypergears SS1PU. That is a very responsive turbo with a super strong punch.

Wait. just noticed OP ask for a Rb20det turbo lol. For that power check out their high flows and the smaller SS1.

    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out. 
    • Wife and I are still looking for a new home. One condition was a large enough garage for a full-size lift in one bay. Now if only we could find something... We've been looking for almost a year now.
    • Thanks everyone for the ideas! Sadly, ramps are a no go for me. With young kids at home, I do most of my work late at night while they're sleeping. Starting the car multiple times wouldn't be a great idea.  I'll go see one of those new long reach low profile jacks and take a couple measurements to see if they will fit.
