gcg said they could do a t3/4 that was not ball bearing for 1800 i think, but if you just go a stock turbo you know what youve got and even if its not right you havent spent 2g

Meggala I just got a hks t04e to put on my 32, only cost 400 and I am modding the stock manifold to take the extermal gate, do you have any info on the turbo, hp rating boost efficiency range etc, thanks.

hey clint its a treeible turbo you don't want it .

you will have to send it straght to me

:lol:

as for info it depends on the the a/r ratios etc.

btw I wouuld love to see pic of the manifold when done

400 hp would be a good guide talk to adam32 as he has one on his r32

meggala

its got a .6 ar exhaust and comp housing, not too big, about 59mm exhaust wheel i think.

the manifold is not as easy as i thought as there is not much room, i was going to do it like the jms onveia but there is less room in a 32 so the plate has to be angled to clear the strut tower. will take pics once its done wont be for a couple of months, as im dooing the inlet manifold as well and need to buy rx7 injectors and the wastegate.

Joel,

You know Tim at RPM pretty well so why not consider the GT28 400HP unit for RRP $2300. It has a small exhaust A/R of 0.63 so spool up should be good. 4" inlet and 0.7 A/R compressor should also give you 200rwkW easy.

All you need is the spacer for both rocker cover clearence and also adaption to the T3 flange.

Basically Tim can only do the T28 or the GT2510 which will only make around 180rwkw.

SO... I poped around a few places today found a HKS EVC which is a dual solanoid and has the rpm thingo and also a map sensor.

Then I came across a jap importers that is getting in a GT2540 next week that is from a GTR, he is splitting them as a friend of his wants one for his SR20.

I might put up with a bit of lag, it really depends if my injectors do end up being bigger than std. If so here I come 2540.

clint32,

fyi, the HKS T04E is actually rated at 500hp and would be perfect for an Rb20DET engine. a little laggier than the standard turbo but power/boost would come on quite hard.

check out the following link, it should give u all an indication of the hp ratings fro all the turbo's mentioned.

btw, a friend has a 400hp GT25 on his R32 RB20DET, along witha FMIC, unichip, and bigger pump and it's producing 222kw at the wheels on 18psi, with heaps more potential.

i guess it all depends on what u want from your car joel.

//RS500.

Joel, what turbo did you end up getting, or are you still deciding?

Have you spoke to Ben at Tilbrooks (Brains) He has a R31 wagon with a HKS 2530 on a Rb20, been in Zoom etc. That car goes pretty hard. It makes around 220 at the wheels, but being auto with 2500rpm stall, I don't think lag is to much of a problem in that car.

I think that fact remains that any bigger than stock turbo will be a bit laggier, but the trade of is consitant boost right up to the redline

I am in the process of getting **** toghether with my car for a bit of a power-up, including turbo, bigger intercooler and maybe new injectors or pressure regulator on the existing ones.

Let me know how you go

Chris

So, just how laggy are these turbos (hks 25 series) ? as i just recieved my gt2535 today and would have thought being a BB turbo and still being reasonably sized it should be quick to spool up. I thought i should have full boost by about 3500 rpm.

My turbo has a .60 a/r compressor and a .64 exhaust housing.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
