Nissan Pulsar GT28 turbo
Turbo Mini Forums

Does anyone have any opinions on this turbo? I have herd it could be a good choice for a 1275 build that im looking into doing, however after a search i carnt find anything.

Opinions on its suitability please?

It may be a bit on the large side. Depends on the exhaust housing size anything bigger than a .49 and it will never spool. The cold side is usually a .42 cover with a 60 trim wheel again which maybe on the large size depending on your application. IMO the rs turbo t3 or a more modern turbo would be a better option.

bit big,

I think evo was using one of these on his K series, came on boost about 4500rpm iirc

Ahh i see, i had been told it was slightly smaller than the T3, yet larger than the T2, however considering its from a 2.0 engine i guess that would make sence.
Thanks

I have one on my R5 it starts to think abou making boost at 4000rpm and then full boost by about 4600rpm.

It would probably work fine. Its a T25 flange with a semi-small housing...cant rem what size.

Compressor would be a moderate sized T3 though. Certainly of the goals are high it could work...but a faster spooling GT series would be better all round

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Im looking for about 170 - 180 bhp so i dotnt think i really need to do anything unsual with the setup, a 1293 with a low Cr and intercooler running a T3 should be enough to achive those goals shouldnt it?

It was just an idea that popped int my head as theres quite a few cheap ones going on ebay.

lol i use one, get full boost on the 1400cc bottom end at 5500rpm.. i would go for something smaller on an a-series imho.

exhaust housing is .86 it is a big turbo

In which case could you shead some light for me? I was origionaly going to turbo a 1275 engine but have been offered a metro turbo lump for decent money. I was thinking along the lines of 1293 with 18cc dished pistons, head work done, avonbar camshaft, decent size intercooler and dump valve, then crank the boost upto 15 to 20 psi. Although i have been now looking into the GT17 turbo as a replacement. Its going to be for a fast road, but still a daily driver!

Oh and a stright cut gearset.

for a daily driver i would stick to 120 / 140 at the most and say 10 psi.

You dont really need 18cc in the piston and a well worked head unless you intend to run massive boost. Cam is a good choice and a GT17 seems to be the turbo of choice atm.

with this kind of power you need to start thinking about mappable ignition too, have a good read on this site there are some great post designed for new members.

yeah you can do, but the lower the CR the more slugish the car will be off boost so not ideal for a daily - but i guess its a good compromise. This is how i use mine (10 psi for road and track 18 psi for the quarter mile) but i dont use it for the daily commute works well for a fun weekend car.

you dont really need the turbosmart thing either, its basically a bleed valve and a solenoid, the same can be made for £40 ish.

where are you based - might be a good idea to have a passenger ride in a turbo mini to see what you need / want etc

Im in Newcastle, that would be perfect. I have a guy that works on the same bussiness park that my dads company is based, and he specialises in mini resorations, which is where im looking at getting my metro from. He has a Metro Turbo, with some modifications to the engine, producing 153 break, but unfortunatly its not road legal yet so i could have a drive, but if theres anyone local running a turbo mini i would apriciate it massivly!

I think thats the hardest thing about researching a project without talking face to face with someone, its amazing how much you can learn from talking to someone face to face!

The Pulsar turbo is far better suited for say a 1.6, 1.8, 2.0.

Got A GTM With A Honda In the Back, and huge Nitrous bottle where the passenger seat should be when racing!
