Turbo recommendations for 280-300bhp

[George182]

I am about to commence my turbo build and I am after some turbo recommendations.

I will be running a forged block and the engine dynamics exhaust manifold.

Thanks in advance!

My T28 is troopering along at ~310bhp approx 1.1bar, cheap turbos you can pick them up for £200. Although imo i do find it a little bit laggy strangley, it doesnt really get into its stride until 3800-4000rpm.

Expensive option would be a GT2860RS ~ £800, probably a better spool up will flow better. Though if i had a forged block id be looking to utilise it with a GT2871R for upto 400bhp ish.

HKS T51r is where it's at









failing that what Laine said

 

[mi16chris]

Gt2860 would be a good turbo

 

[r0ss172]

I use a GT2860RS - Good for up to 350bhp

 

[Chip-mk1]

T28 is a very vague term, all depends on the trim and size of the wheels etc.

Are you looking to buy new or secondhand?

 

[George182]

I have budgeted for a new one, but a reconditioned unit would be ok with me.

 

[Chip-mk1]

If you have the budget for a new one, go for a GT2860 IMHO

Be careful though with what you ask for as that is a very vague description still, id go for the 62 trim inlet wheel (47ind and 60exd) and then personally I would go for the .86 A/R exhaust housing, and sacrifice a bit of spool for reduced EGT, but you could use the 64 trim variant if spooling quickly is your main concern.

Let me know if you need putting in touch with a decent supplier.

Its vital to know what you are talking about when ordering a turbo.
Saying "t28" or "gt2860" is like saying "ford escort", without the specific details you dont know if its a 1.4 popular or a cosworth.

Chip......im new to here and only joined by virtue of the fact my dorris has just bought a 172 cup....im more used to building and running high powered Skyline GT-R's..........your advice is spot on my friend. I was expecting to find a lot of snotty nosed kids on here talking a load of bull about boost n boobs......... By the way ive got a nice pair of Nismo GT28 turbos looking for a new home soon as ive got 2 bigger units for my R32 GT-R........one of these would offer upto 300bhp and almost instand boost on a Clio.............infact I might throw one on my wifes cup.......lol

 

[godzillar32]

Oh....and to the OP.......please lets use the correct terminology......forged engine, not forged block....lol

What spec are the turbos? wheel size and trim etc?

 

[George182]

Thanks chip - I'll have a read of that and I'll almost certainly be taking you up on your offer of help around suppliers.

In future I won't say 'forged block' either

​Thanks for all your suggestions guys

 

[Chip-mk1]

Shame there isnt a forged block available for the F4R, would be epic especially if a bit taller than standard so I could correct my terrible rod ratio!

 

[batesey]

I'm running a gt2871 replica, it starts spooling up at around 3k and by 4k is flying, I could get hold of one for you if you wanted

 

[George182]

I have purchased a gt2860 now.

Thanks for everyone's suggestions.

I'm going to Run a 2871R on a 182 engine at some point this year..

Is it a gen Garrett one or a copy?

What did you pay?

 

[George182]

I am assuming it's a garrett

​Came to £850

 

[George182]

Cr have confirmed its a genuine garrett ball bearing turbo.

The fun starts here!

 

[r0ss172]

Good work! whos doing the build for you ?

 

[George182]

I am taking the plunge myself..

Wish me luck!

Ah cool, if you got from CR it will be spot on, brilliant guys to do business with

Yep agree with that comment Chip after you sending me to them

 

[Chip-mk1]

I dont ever send anyone anywhere else for turbo stuff these days TBH mate, CR always come out on top with everything Ive dealt with so I literally dont bother phoning around anywhere else now.

They've done me a nice billet wheel upgrade on my turbo when I got it rebuilt too

Fair play get a thread up, you will get endless help from the turbo boys on here especially Andyrg and Chip.

Yep 24 hr turn around on rebuilding my GT28RS, looking forward to seeing it and finally going out with you in it when its all built back up!

 

[George182]

A thread is a good idea, I'll sort something out.
​
Thanks again for your recommendation to cr chip.

 

[Chip-mk1]

No probs George.
