Turbo Set Up Options Question


Recommended Posts

Am planing do few mods on my stock R33, Iam planning on doing the following mods,...1.high flow stock turbo 2.full turbo back exhaust 3.electronic boost controller,running on a mines ecu at less than 10 psi boost. so here is my question iam on a budget so would like to know which intercooler to go for, i have two options only either a cheap e bay intercooler or a stock r34 , my worry is which one would give best perfomance for the price.Iam also worried about turbo lag with the e bay one , not really sure, i think ive heard that big intercoolers on small setups causes turbo lag.. is this right ?

If you are worried about lag, then you need to not be a tightass :)

Given the two things go hand in hand.

Sorry to tell you but a MINES ecu is not good enough in any way, shape or form. There is also no point spending money on parts and running 10psi and no tune. You are better off not spending a cent and leaving the stock turbo on there... Then spend the money on coke, booze and hookers.

However if you are prepared to get a tune etc etc.... And want to do it on the cheap you have many options, only a few reasonable however...

1. JJR cooler kit (SAU Sponsor)

2. JJR exhaust or just get a 2nd hand one off the forum

3. Hypergear turbo (SAU Sponsor), just using actuator.

4. Tuneable ECU + tune

~ $3500 if you are lucky. If you are paying a workshop then $4500 if not more.

The above will give you an average 220rwkw or so. Won't be the best setup.

If you want more power you will also need to factor in things like AFM, injectors, coilpacks - $1500

Also to take into account are.... clutch, brakes, tyres and most likely a diff.

They will cost anywhere from $3,000 - $5,000.

my recomendation just jap return flow cooler. i have a hybrid cooler on my vl running a stock r33 rb25det with microtech ecu the lag isnt to much of a problem i hit full boost around 3800 i think however im going larger turbo soon so shouldnt be to much of a problem. the jusp jap is great if your on a budget and i have heard nothing but good feedback about them

R31Nismoid i understand and appreciate your comment but the reason why iam going for a budget setup is because iam doing what i can afford, the car is not for any track use at all, and i dont have any power figure targets in mind at all, the only reason iam doing the turbo is because iam trying to avoid a turbo failure and gain tiny bit of power with the few basic mods.therefore just needed to know what intercooler will serve the purpose with optimum perfomance

i ran 350rwhp with china intercooler on a highflow. will be fine. just done go too cheap, somthing around the $300 will be fine but you wont get pipework with that :thumbsup:

p.s. throw the mines ecu in bin and get SAFC2 minimum

If you don't run more than 10psi, the stock turbo wont die.

It's when people push 12psi+ they get agro.

and you wont need any parts, coolers and you might be able to get away with the MINES ECU (but i would get the AFR's etc checked in a dyno first)

yeah if you are on a budget the best thing you can do is get the max out of the stock turbo setup. this means safe, but you can net yourself some good gains by doing so on a budget. my setup went from 140rwkw to 193rwkw which makes for a fairly quick car on the street, not much can beat you in most "legal" situations, even the vlt's and xr6's, xr8s etc will struggle to beat if you can drive. i was able to net 13.7 with a f**ked diff and 0 to 100 in 4.8 so you dont need 4000rwkw to get good times or a quick car

get a good tune with a good setup (nistune, safc, anything but a MINES ECU)

good intercooler

good intake

good tyres and clutch

the stock ER34 smic is ass, dont bother

either upgrade the standard SMIC to a frount mounted item or dont bother, a SMIC is a waste of time and money

All I had was an excedy HD clutch walbro fuel pump and a boost tee at 11psi with stock ecu and a tune it was doin about 185kw..was enough to keep up with just about everything on the street ..Stock cooler did me fine too..

but yeah id go..

jjr turnflow 400$

walbro pump 200$

turbotech boost t 30$

full service and tune 300$

Any secondhand exhaust will do.

should net you a healthy 180kw or so then start saving for a clutch..

If your turbo does blow rebuild with steel wheels and your good to go again..

If your on a budget and not chasing a lot of power then just keep the standard turbo on the car, not going to gain anything by putting on a cheap turbo and running 10psi.

Dont bother with a mines ecu as there rubbish, i have never heard of one actually having a decent 'tune' on them.

I would just a front mount, boost controller, exhaust and a tune. You should be able to get around 180-190rwkw easy with a 25 while still keeping the standard turbo, injectors and afm. If you go a front mount get a return flow, they may be more expensive but it saves you cutting up your car and a return flow cooler is legal.

Spend money on a decent tune, nistune would be perfect and at least you can keep your standard ecu.

I personally would stay well away from the cheap ebay turbos, for the same or fractionally more money you can get your standard turbo highflowed by hypergear and atleast you know it will do the job and not shit itself, but unless your chasing more then 200rwkw dont bother upgrading.

I would be doing this.

1.Exhaust $500-1000

2.Boost controller Turbo tech $30 best cheap one on the market

3.Intercooler Return flow $700

4.Tune $850-1000

5.Fuel pump $300 standard might be fine though

Will be safe and reliable and what i would consider cheap considering the gains.

thats about it there, concentrate on supporting mods that you can use in the future IE good exhaust some management good boost controller, i have heard that the r34 smic is good for about 200rwkw but i could be wrong.

Out of interest, whats the budget?

and to clarify the 34 smic thing, its good for 200rwkw if you only give it the odd squirt, doing hills runs or constant boost and i agree with paulr33

yeah the prob with the stock SMIC (any stock SMIC) is it's location and core size

once it has some heat in it, from repeated boosting - the core is practically useless, i bet its too hot to touch on both sides after a twisty road quick thrash

i see no legit reason to keep a SMIC or upgrade to the ER34 SMIC

most of the other mods make the car defectable just as much

    • As an extension of that thought, if you do not also have adjustable front radius/traction arms, and if you have not had them properly** set up at the same time as any adjustments to the uppers (when camber is being set) then you  will likely have an excessive amount of bump steer and the rear end will actually be worse off. **I built a bump steer measuring setup with a laser, mirror, etc and spent.....a whole day, and most of another day, getting both sides of my car to minimum bump steer. (Was a slow effort because I was designing/building the rig as I went, to start with). Then I had the rear camber adjusted a little at the next proper wheel alignment and had to set the bump steer rig up again to dial out the increased bump steer that it caused. Car's rear end behaviour was substantially nicer afterwards. To get that done by a specialist would be.....near impossible in most places. Almost no chassis/wheel align shops would be willing to put up with the f**king around. And the fee would be horrendous. Racers and shops that cater pretty much only to racers would probably be set up to do it and do it reasonably efficiently, but it would still cost many hundreds of $$. My time should be worth even more than that, but fuddling about with the car is also therapy, so meh.
    • So about 10 years ago, i bought a brand new Greddy FFP (a legit one), which i have always wanted to put on. Now i know there is no real performance gain, however i have always been a fan of how much it simplifies the engine bay and makes servicing that much easier. The reason i never got round to installing it is that it just seemed more trouble than its worth for basically a stock car.. All mods to date are more suspension/handling/drivetrain, so today i made the decision to start with the more serious (and expensive) part of the mods, the engine hardware.. Today i purchased: Xspurt 1000cc injectors (1/2 height) EFI Hardware fuel rail GFB FX-R fuel pressure regulator necessary fittings to direct mount regulator to rail NZ Wiring trigger kit 82mm Bosch DBW throttle body Taarks 82mm DBW to 3" hose clamp adaptor Outsider Garage 350z pedal kit Franklin Performance R35 GTR coil kit There is still a bit of time before this will make its way into the car, as i want to have a complete cold side assembly, with a sub-harness all good to go. As a note, i have heard the the 82mm Bosch DBW throttle unit is basically a direct bolt on with some very slight mods to the plenum, so will be testing this out.
    • Awesome, thanks for your help👍👍

It also goes to the oil/coolant heat exchanger and the throttle body. The hose it attaches to is 92400, which is the upper heater core hose. The one to the right of that goes to the lower heater core hose. In the absence of proper photos at each step showing how everything is laid out from the factory the EPC is as good as it gets.
    • Hi All I’m Rene, based in Hamilton NZ and am the owner of a silver 1996 R33 coupe. I bought the car in August 2009 and I am the first owner in NZ. When I first purchased the car, it was a bone stock gts25t automatic with approximately 75,000kms on the clock. From memory I paid about $8,600 from the dealer:   Mod History So over the years I have done a few modifications. The first real mod I did was wheels (on stock shocks) and tints: Now this was done prior to finding out about SAU/SDU, meaning I had no understanding about things like fitment, so was rolling round in 4x4 spec for some time.. Eventually I became a bit more educated (thanks to the forums) and started to do things a bit better. Rather than write a novel of the last 13 years of ownership, I thought I’d just add the list of mods: Exedy lightweight flywheel Exedy full face organic clutch Braided clutch line Adjustable whiteline swaybars (front and rear) Znoelli dimple drilled and slotted brakes with performance pads (front and rear) Braided brake lines (front and rear) BC Gold adjustable suspension Hicas lock bar Tomei upgraded fuel pump Genuine Greddy front mount intercooler kit 3” exhaust from turbo back, with 3” bellmouth dump R34 OP6 turbo Mishimoto aluminium radiator ATP catch can and speedflow fittings 17x10r and 17x9f wheels with Falken fk452 all round Innovate mtx range gauges (oil, wideband and boost)  Funnily enough, this list was actually composed to add to the classified to sell it, however I just can’t bring myself to do it. Did you say M3 @Dose Pipe Sutututu? Anyway, this brings us to the current day The car now has 105,000ks and is barely used as I just don’t have time and it doesn’t really suit being my daily (as I need something more suitable to visit construction sites). I don’t think I have even driven it in the past 12 months.. Build Direction The plan here is to go for a bit of an OEM+ type vibe, so nothing too extreme. I am also planning to modernise a lot of the vehicle with things like new ECU (decided on Haltech), DBW, cruise control etc. The power will eventually get increased with an end goal of around 280-330kw. I am keen to get a bit more motivation and actually get this car build back up and going again. It may not be the fastest build, but I’ll get there eventually! And then I’m less likely to try sell it..
