T3 Turbo and Manifold Recomendation for Drifting

[Radial]

Hi there!

I have my 1JZ-GTE/R154 in a JDM JZX90 "Mark II" Chassi, built as a Race-car for Drifting. The JZX-world forums wont accept any of my email-accounts, so I just gave up asking them, but the Supra MK3 uses the same engine so I thought ill ask you.
One of my stock turbos are probably having some serious issues...impossible to boost more than 10psi below 4000rpm, BOV-sound even with Stock bov completely blocked, and an minor oil-leak from the rear compressor-housing. Probably some WG-issues, worn turbines and probably a worn gasket on the shafts. But it's drivable and works OK through the rest of the season (but missing some power and lots of response of course)

So, a "new set" of used stock ones (500$) feels like a big waste money as this car will be driven Extremly hard, and i need as good spool as posible, so i'm planning on going single this Winter (I live in Norway, northern Europe).
As my ECU and Injectors are both stock at the moment, and future powergoals are max 400-430whp with max boost as early as posible, the T4 flange and housings will probably be To big for me. I sorted out that a T3-manifold with a decent turbo and External WG might be the best solution.

A good friend of mine is selling his Turbonetics Stage 3 E46 turbo, but i think this turbo is a bit to small for a 2,5L application... but its almost new and goes for about 550$.
But, what is the cheapest, but best option available for 400-450whp? I will get some 440cc injectors, FCD and a SAFC later on.. but I have to be able to test it with evertyhing in stock. Peak HP is not important, I can live with lower top-end power if i get max boost and Torque as early as posible. Holseth, Garret, Turbonetics, OEM branded turbo of some sort?

I've been searching all across the internet for recomendations, but all i can find is turbo-recomendations for big numbers, and thats kind of a waste in drifting where you in reality want the early torque from a big V8, in a 2,5L with the sound of the six cylinder

All answers are appreciated.

Cheers!

Get 550's if you are going to make over 400hp.

Small and quick spooling. Top end might suffer some tho since the a/r is only .63.

hy35 will come on line pretty quick as well.

Ahh.. i need 550's to reach 400? Damn, those are a bit more hard to get Have plenty 440's available We have 98 octane available as pumpgas over here, that might help a set of 440's? I'm currently using Wideband-lambda to check the AFR's so it will be somehow "tuned" with a wideband

Those Precision-turbos looks like a bargin! How about this 3231E?

How are your experiences with the XS-Power T3 manifold? It will probably crack somehow after some time, but ill try to reinforce it a bit.... its so damn cheap, 250$ with international shipping!

 

[hvyman]

There is other places that there just as cheap than eBay.

Xs power manifold will work fine. I'll be usig a cxracing one. But t4.

Do you have a link to such turbo-site?

 

[ehall8017]

you can't go wrong with a precision turbo. especially their new billet series turbo's. there probably the best on the market right now or close to it

 

[Radial]

Yeah, I have done some research the Precision turbos, and their "new" entery-series is not talked mutch about... but I guess they cant be THAT bad spoolwise, as they all have 360 race bearings and small/medium size 54-57mm turbines and deecent A/R-ratings... It seems like the whole world is in Garrett's pockets, as none's considering anything other than a expensive GT3076R on 1JZ's no matter what power they want. I am considering theese two turbos for now:

http://www.precisionturbo.net/turbochargers/entry-level-turbochargers/details/Entry-Level-Turbocharger---5431E-CEA/58
and
http://www.precisionturbo.net/turbochargers/entry-level-turbochargers/details/Entry-Level-Turbocharger---3231E/57

Looks like the only difference is in the Compressor....CEA-stuff on the 54-series, have noe idea what that means though...

Does theese turbos need a restrictor for the oil? And will a "garret T3 hose-kit" for a 1jz fit theese turbos?
And I cant figure out if I want a 4 bolt or 5 bolt...hahaha

Anyone who knows of a shop cheaper than "Egay", just bring it on!

 

[ehall8017]

no theres no restrictor needed on the new precision line unless you use bigger than a 3an feed line.

also, im not sure if the garrett hose kit will work. it would probably be cheaper to just piece your own feed line and return line together.

Spend a little on the turbo. Its worth the investment. Trust me. Plus those entry level turbos are a bit small for you power goals.

I'd love to invest a litle on the turbo, if I'd get an early spool and a good TQ curve on a fairly stock engine. The whole reason looking at small turbos is because im looking for instant/stock(ish) spool, and some 400whp capabilities without the need to invest 3000$ on tuning and a hardcore Standalone. the stock twins can manage 400bhp (not Whp) on E85, many of my compeditors are running that on their JDM Soarer's But they are not very reliable at that powerlevel and you are required to always have a set of spares... and as theese engines and the turbo-technology is 20 years+ on age, it just has to be somehting Better in 2011 with the similar spool of the twins?
As E85 is easily accessible over here, so I might convert to E85 later on.. the fuel-system from the tank etz are already prepared for it. (new MK4 Denso pump, New 12v source direct to pump, a clean tank and new filters, etz)

How would a PT5557 behave on a stock engine? Maybe I should email Precision?

 

[ehall8017]

yah precision should be able to help you out the best on which turbo to buy if you describe to them what your looking for.

 

[Radial]

hahaha, Precision clearly cannot recommend anything!! The reply to my email, came from a sales-representative told me to contact my local Precision-dealer... So I have sendt a new email to the dealer now, but iv'e been in touch with him before.... he was extremly expensive at that time, so im very curious abut the reply!

Ill be back with information about the recomendation... he's a Very good and experienced tuner though... worlds only 1700bhp 3,4L bmw M5 engine in an old M3 and runs / 7.70s@ 1/4mile

 

[hvyman]

If you know how to plot a compressor map you could see exactly what would happen. But there is some math involved in that and it can be a tad trickey.

Something with a 57mm wheel would work fine.

 

[bigpanda16]

Sub 400 is ok with your commonly available 440's, plus they are a direct swap. You will be up in the duty cycle though.
Go with the easy cheesy Chinese t4 eBay manifold with a t4-t3 adapter, it won't raise your turbo up too much.
Hy35 would be good; my bud's he351 doesn't spool till 3600ish, which makes it a bit of a drivers car, unless you're at a circle track... His does 380rwhp at 18psi on aristo 440's

well folx, I ended up buying a BW S200SX RS-51 from AGP-turbo with .75 Twin entery and 3" V-band outlet.
http://www.agpturbo.com/borg-warner-agp-s200sx_rs_51-turbocharger/

I found the compressor-maps of the Airwerks-version and my 1JZ will hit the highest island on the map at 16PSI. (35lbs/min)
Compressor can also deliver up to 47lbs, claim both AGP and Airwerks
So, as AGP and Airwerks BW's are identical in sizes, and both have the BW geniune internals..differences are minimal.

I will mate this turbo on a HKS T3 TwinEntery manifold I got hold off with a 50mm Wastegate (HUGE!) preset at 12PSI.

The SRT-4 (2,4L inline foru w/turbo) community commonly uses theese turbo's, and they claim 20psi at 3000ish with a singlescroll on cheap cast iron manifold.... So my 12psi ,on a bigger engine ,and performance Twinscroll-setup, should hit full boost easily in the high 2000rpm area, hopefully earlier.

Funny thing is, Turbine is 60mm, so there probably wont be mutch backpressure at my powergoals...:naughty:

I'll give you a heads up with my result within a few weeks! Just need to do some differential-work first, as my buddy's crappy welding broke on my qualifying run, sending me in a ditch full of gravel....dohh..!^
thank god it was the last event for the season, got some good 6 months till next race

 

[Radial]

Just a little heads up, even though the thread is old:

I am currently running the T3 twin-scroll setup with the AGP RS51 turbo at 14PSI, with stock injectors and ECU.
AFR's at 10,5 on full boost... so no problems with fuel, thats for shure!!!

A little disappointed and little happy about the performance;
I have full boost at 3200 (kinda slow..??), but power won't come in before 3500-4000rpms but then of course it kicks some serious ass up to the redline... and clearly wants to give you more, if just turning up the boost (but I can't due to Fuelcut etz). The turbine is probably big enough

So the downside of my turbo-setup pr date is the initial turbo-lag.... if you fall underneath the 3000 mark, you need some serious clutchkicks to get the performance you need on tight corners. It requires a different style of drifting then i'm used to, but i'll get used to it.
I am however optimistic about the future, as the ECU is stock, the Ingition and Timing is Stock, and the AFR's are still Very rich. With aftermarket ECU, and some bigger injectors, some ignition and exhaust timing advance... and leaning out the mixture to a 11,5:1 (or something) i think it will be quite nice.

Will try to lower the fuel pressure a bit with a adjustable FPR to force it a bit leaner for the rest of the season

A few pictures:

The HKS T3 MA70 twinscroll manifold, modified for a slightly more narrow JZX enginebay (You can see the wastegate is re-routed. pre-welded with MIG, ready for TIG welding)


The Turbo and manifold test-fitted:

The overall enginebay after modifications:



The radiator is the largest one from the US brand "Flex-A-Lite".....3" thick... after hours of drifting, the temperature never exeeds 85C/185F. Great radiator :love:

you dont have to have 550s to make 400.. i made 413 on the 440s. but i am prob maxing out the injector at that point.. and in short burst thats is prob ok. but for constant use i would go 550s
and i cant rembere exactly what trbo i had, but i belive it was a older version of this one http://www.precisionturbo.net/turbo...ails/Entry-Level-Turbocharger----5831-MFS/492 with t3, and ar,63

 

[Radial]

Yes, iv'e read allot about 550's vs 440's in six months now... Your powerlevels on 440's are very good, but as you say...the duty-cycle is dangerously high.
It's probably easier to just go for aftermarket 700-800cc from SARD or similar... with stock or aftermarket fuel-rail (depending on application and price). As long as the ECU is aftermarket, the options are many

 

[f00g00]

The cooling system is probably helped by being only an oil cooled turbo. Any more info on that manifold?
