Hi, im chasing either a GT28RS or a GT2871R. Who gives the best price? Many thanks

a good mate of mine can get garrett turbo's cheap

where are you located?

Try Fantasy on these forums. he does some good deals.

Horsepower in a box, $1395.00 delivered.

Here is horsepowerinabox $1430. http://www.horsepowerinabox.com/HPIAB2/prod176.htm

I will match this price.

My email is fantasyy@bigpond.net.au

how bout the gt2871???

The GT28RS is a better turbo and you will make more average power with it. Just ask discopotato from these forums, this guy is a turbo expert and knows turbos better than garret!!!!

You will make more power with the GT2871r but you will have a slower car and lose heeps of lowdown torque, and I mean heeps. GT2871r is a mismatch turbo. Do a quick search on the net on the atp turbo site and you will see back to back gt28rs vs gt2871r, the winner is obvious, its not only power which makes your car go fast!!!

Discospud, I wish i had gone this diretion...and i will.

Stupid question. Since the GT28RS is an internal wastegate, will she bolt up the the standard manifold?

it uses a different flange mate, so no.

it has a t28 flange and standard manifold is a t3 flange

cheers

Thanks mate, i was thought it might be like that. I think ill be in contact with Fantasy soon since he makes some very nice manifolds ive seen, and supporting him would be supporting fj20.com in a way. Still thinking about the GT287R since the car is driven once a month or so. Interested to know how many rpm it needs before kicking in. Ah, the lure of horsepower. Thanks heaps to all.
Also, what can be done with the standard T3? Cheap boat anchor?

Look and you make your mind up. As you can see the spud can flow 300rwhp easy and if youre vtec even more.









I quote this from disco: (note this was for my CA but equally applies to the FJ20)

How an engine pulls from the low/mid range is more important for achieving faster average speed and shorter times . A successful racer needs a close ratio box anyway so the last 400rpm is a bit trivial if you can pull the next gear and not fall off the power curve . Cars raced with production ratios suffer because the syncromesh cannot cope with the gear speed difference and quick changes . The only option with std ratios is to develop the engines power curve to be broad and not starting too high in the rev range . You probably need to think about the engines torque curve more than the Kw curve . Remember horsepower/Kw is torque x engine speed , eg if the torque number is the same at 4000 as 6000 all thats changed is the engine speed . Manufactures love to quote Kw figures because its always a larger number than the Ft Lbs / Nm and its mores law that sells , the average driver probably never gets to the redline .
Back to turbo's , on a CA18 the GT28RS will give a more usable torque curve than the GT2871R , you will loose usable revs to lag because of the compressor/turbine miss match . I can't say how much because I've never seen the spud on a CA18 . Also don't forget The spud with a really good filter system/dump/exhaust will eat the 71R with average bits . You really have to optomise everything else and then upgrade the turbo . My vote goes to the spud .
Cheers A .

Last of all, go to Nissansilvia.com, go to the sponsor sections and write to horsepowerinabox. He will beat anyone on turbo garett prices and this is the same for ray hall turbos.

Hope this helps

French, with thanks for the info. You are right, the RS will make a faster car in the real world and thats where it matters for me at the end of the day.

Thanks champ

One very important thing to note is that the GT28RS is intended to be used with the .86 ARR exhaust housing , that number sounds big and is by T25 standards . Do not try an equate it to GT30/T3/T04 housings . As I mentioned somewhere I was getting positive pressure just by 1600 rpm , on the street not by dynoing at constant speed . I would not put the .64 housing on anything over 1700cc's . Spud turbo does not like to choke on the exhaust side when the revs rise . The 86 is what they're designed to run and come up trumps on the flow test rigs . I wished at the time that it was a touch larger but the original evaluation unit (in house petrol head rat turbo) was for a circuit Mazda BP18 Miata (MX5) with external gate for which it was ideal . Go the .86 - can't stress that enough .
Cheers A .

Although not as cheap as other options, this guy might be worth a look, seems to know what he's on about, and the manafolds look tasty

what about the 400hp GT28 on horsepowerinabox. does anyone have any info on these. a good choice? compared to a disco spud? and what rear housing would be the go. thanks

GT28RS

Turbine
-Wheel: 53.85mm w/ 76 trim
-Housing: .64 or .86 ar

Compressor
-Wheel: 60mm w/ 62 trim
-Housing: .60 ar


GT2540R (also known as GT28)

Turbine
-Wheel: 53mm w/ 62 trim
-Housing: .64 ar, .86 ar

Compressor
-Wheel: 76mm w/ 48 trim
-Housing: .70 ar

GT2540R is a mismatched turbo. Look at the difference in sizes bt compressor and turbine and compare it to the same difference bt GT28RS. The GT28RS is far better. If not, your next solution is not the GT2540R.....ask the discopotato king. Hell tell ya what the next best solution is.
