Turbo choices and your opinion's.

[Logan76]

Alrighty im on a budget, me and WDracing were talking and what do you guys think about an RB25 T3 turbo + SSAC top mount manifold and a tial 38mm external wastegate, ( I only found SSAC T3's that were in topmount and had EWG flange), custom DP based off my megan one, and some RX7 550's and some kind of management possibly an SAFCII + FPR? I dont want to break the bank but I can get alot of this relatively cheap and it sounds like a good way to up my ponies, all input is valuable to me. thanks.

[Swedish Mike]

Hp goal?

[Logan76]

hmmm 275ish.

[The_Chosen_One]

GT28R would be your best bet honestly.

With my GT28R on stock manifold I was building boost at 2200rpms and full boost at 2700rpms, with SSAC manifold I was building boost 2600rpms and full boost by 3100rpms.

With the proper supporting mods and tuning you can be around the 300whp mark.

[themadscientist]

They are hard to find, everybody wants them. I would suggest if you have a T3 manifold buy a new guaranteed T3 or T3/T4 stateside.

[Logan76]

Gah I dont have lots of cash to throw around Im just looking for a decent hp goal cheaply and it seemed SSAC manifold + rb25 T3 I could get decent hp, I dont have 850$ to drop on an GT28RS, I may just get my buddies SR T25 and rock it until I can save to buy a new bigger better turbo.

[The_Chosen_One]

I didnt say GT28RS I said GT28R and they can be had for as low as $600 NEW thats how much I got mine, plus its a bolt on affair to stock parts so you'd save money their.

Either way you go you should be good. Also 550cc RX-7 Injectors I'm pretty sure are High Impedance.

[themadscientist]

The problem with a used turbo is you get, well, a mystery. You can wiggle it and spin and stroke it provacatively but in the end you never know what it will do. It may pop on the first full throttle run or it may last years. Taking this into consideration is it worth the gamble? A used turbo should be half the price of new but when a used turbo lets go what customer support number do you call? This is why I don't sell used turbos unless the guy is standing right in front of me, inspects it to his satisfaction and fully understands I accept no responsibility for it's performance.

[anumeric]

IIRC the 87' and earlier FC 550's "tan tops" then their low impedance. 88' and newer 550's "purple tops" are high impedance. Someone correct if I'm wrong.

As was previously stated, the GT28R's are getting to be a decent price now. Unless you've got a line on an RB T3 for a good price, they may be harder to find at a decent price than you would think. Also, going with a T2 series turbo is going to greatly simplify the installation, and may offset the cost of a new mani, wastegate, and custom DP.

Regardless you'll need bigger injectors, the 550's are plenty big, and you'd prob be fine with 470's. A bigger MAFS may also be in order. If you don't have a walbro already you'll need one, and if you put the walbro in, it could very well over run the stock FPR, so you'll need a FPR and a fuel pressure gauge.

[Logan76]

I have a walboro right now and im running stock FPR but thats soon to change, I havent seen any problems as of yet but I dont want any later down the road.

TMS - I totally see what you mean and can agree with you 100% there, Ive now figured its my best bet to just get my buddies SR T25 for 100$ and wait until I can afford a bigger T2 series turbo or upgrade to a T3 super 60 + decent manifold and custom downpipe.

[Woods Crasher]

For my CA, I"m going to go with a GT2871R with a 0.64 A/R, Cams of some sort, Perhaps these 270's that are stickied if they're still around when it comes time for to to buy. 550cc injectors 255 pump Nismo FPR. Gonna try that XS power/ SSAC manifold and see if it cracks after 2 minutes. probably gonna have Jimmy Wolf make me an ECU program because I'm lazy. I would like to run at around 1 bar of boost if the bottom end can take it, if not I'll just run low boost until I have my bottom end built on another short block I'm getting(and then run 1.5 bar ). I think this setup will make a peppy CA with a nice torque curve.

[matty]

show me where you found a gt28r for 600 new, cheapest i found was 790 new.

were talking a genuine garret unit right? not a no name knock off?

[silentkrnsouljah]

i was wondering if anyone has GT28RS turbo or any other turbos by ssautochrome its cheap but i dont know how long it will last and if it will bolt on right awayreason why im asking is i was thinking about gettin me one but i always wonderif anybody has them and how they works

[Chris859]

There have been several posts regarding the ssac turbos... STAY AWAY. There are tons of people that have had those fail within a couple days, to a couple weeks. And a couple people claim they have had them longer - but if 9 out of 10 are junk - why chance it. If anything get a journal bearing turbo from them(because the ball bearing turbos can't be rebuilt), so you can have it rebuilt somewhere reputable WHEN it blows.

[driftnslide1]

well what kind of budget are you on for the turbo? what kinds of boost do you feel comfortable making on your engine and when do you want the boost to kick in?

[silentkrnsouljah]

well im thinking about gettin sr20 T25 for now because im runnin stock ca turboand i heard those are weakk and definally not more then 15PSI or which ever is max for the sr t25 with stock injectors

[The_Chosen_One]

show me where you found a gt28r for 600 new, cheapest i found was 790 new.

It was a 1 time deal by the company Drift Motion. I purchased it before Garrett forced a nationwide price match with all its dealers.

Ask C-rad he got his for $695 new as well.

Yes their both real authentic Garrett units.

[matty]

gotcha

[nocwage]

T3 Super-60 is probably the best BUDGET replacement.

It's a good match to the CA18, the lag isn't that bad at all and you can make 250whp no problem with it.

I had a weird problem with my butterfly valves that I discovered too late to correct my tuning much but I made 223whp at 14.5 psi on my T3 super-60 setup and I know I will make a lot more in the summer when I can start tuning the car again. (My silvia doesn't play in the snow)

The T3 Super-60 is CHEAP.. mine was $535 CANADIAN for a brand new one.

[r34 gtr]

nice thing about the garrett gt28s are the WARRANTY. its a relatively small turbo in the grand scheme of things, but its a great match for the ca18. mine will make 20lbs by 3700 no problem! it also has that nice feature of mounting in the stock location and using the existing oil and coolant lines.

[tyrannix]

didnt 'overboosted' have a t3 super 60, but making 400ish WHP? (with supporting mods and management of course)

yeah with a .48 exhaust housing to assist in faster spool. boostboy has told me to stick with a very small exhaust side to maintain good spoolability

What´s the max power you´ve seen using a .48 turbine housing?We maxed a Turbonetics out at 400bhp but all turbo´s are different.

[BACARDI_DWB]

well there is a good reason that the GT35R's only put out a .63 housing. i think you are right on that .48=400hp or in that area. i wouldn't want to push it more than that in case of surge/backpressure. I plan on running .63 on a GT35R but that is me. Im special, my mommy says it every day

Haha, I guess the .48 housing is the best option for a 300hp engine but I´ve always used bigger because of the cost, not the need.

[BACARDI_DWB]

well when you say that you "use bigger" is that on personal cars or the drag cars that you built? cause on drag cars (depending on gearing) you normally want a larger ar housing due to the ability to run larger boost levels on smaller turbo's with not running into surge. they can prestage and rev limiters to launch off the line already in boost and not have to worry about lag. street cars/drift/autox cars all need to beable to spool quick for throttle response. just wondering what you used personally

We can´t buy the smaller turbine housings to the same prices as you do and that´s why we use bigger ones.Only tried .48 one time at a 1.8 litre and it maxed out 50 hp before the limit Turbonetics gave us. A .63 solved the problem but laggy as you say.You can always learn to drive a laggy engine on both track and daily and that´s what we´ve done in the CA case.My favorite CA turbo is the Mitsu ones from Volvo but that´s also because we get them cheap here, 200-380hp depending on size but they all got big turbines because of the 2.3 and 2.5 litre engines they are from.

[BACARDI_DWB]

yes laggy cars are fun, at least in my case. I LOVE coming up from behind and destroying people. its hilarious.
