what turbo

[tony k]

in a bit of a pickle dont know what turbo to get so i thought i would post it on here to get more of an idea my mates dont agree on certain ones so here goes i m looking to clear 300 bhp just had my engine built i have got a custom manifold

gt28rs
t3 hybrid
t35
or get my standard one rebuilt

[novacraig]

what litre is the engine and and what the spec of it

[tony k]

c20let i have had the head polished and ported (fast road head) had the bottom end lightend and balanced got accurlite pistons its the blocks been ringwired

[novacraig]

well all three of them turbo's will hit over 300bhp but i would go for a gt28rs

[Vauxwhore]

I agree with craig a GT28RS, it would see you 300bhp. I think the output range is 250-320bhp.

[novacraig]

but if you wanna easy hit 300bhp then i would go for a t35 turbo but it would take a while to get to full boost but as the gt28rs would be alot quicker

[tony k]

i have seen a few on ebay from america or are these copies

heres the gt28rs

they are piss poor copies. you want to be looking at about $800 for a legit garret from the US.

I assume your "custom manifold" has a suitable flange for all those listed (and suitable management to cope with the new turbo)

[R1CH]

I'm running a std 4wd Cossie Garrett T3 on mine, running about 290bhp
Only went for that as my std K16 was on its last legs, didn't want to go for huge power or have loads of lag so after doing a little bit of research was told a T3 would do the job.
On the rollers the bhp didn't change much but torque went up by about 60ft/lb, on the road it comes on boost a bit earlier and boosts up a bit quicker, you can pick them up for a decent price on Ebay to, go for a genuine Garrett one imo.

Aye, you have to be careful with those from the US.
You dont want one like Phil Sutton had, that just fell in bits iirc.

[R1CH]

I know of folk running 'cheapo ebay turbos' without any probs, think its just luck of the draw !!
At least if you go for a genuine Garrett (or other decent make) then you know the quality is there, i'd always pay a bit extra and go for a Garrett.

[tony k]

how much is it to get my turbo rebuilt to cope with 300 or where can i get a decent t3 from i was saying to my mate about them ones on ebay saying they look cheap to cheap cheers stuart

management wise im going with omex the 600 one

[R1CH]

Keep an eye out Ebay, also have a look on Passionford.com for some 2nd one.
Buying a 2nd can be a bit of a gamble, but you can get some bargains. If you can remove the housings then you can check the condition of the wheels are ok and that they spin freely then as long as theres not excessive play in the shaft you should be ok, also check the housings for any cracks or marks from where the wheels have been rubbing. All turbos will have a bit of in / out play on them, journal bearing turbos (T3 ect...) will also have a small amount of side / side play as well.

[tony k]

gonna keep my eyes open

[tony k]

[tony k]

anyone

[R1CH]

1st one IMO is Ebay tat, 2nd one looks genuine (Garrett / Airesearch) so could be ok, you'd be best finding out what size housings ect .. it has on it.
Have your self a search on VauxSport.com theres quite abit about T3's / T34's and turbo sizing on LET's ... worth a look.
Your also gonna need Oil feed / return fittings and water pipe fittings (if its water cooled) which aren't always included.

Rich

[BIGS]

depends what power your going for really. as a standard turbo can go to around 300 bhp

[bobby p]

ive put an mvaux kit on mine the t34. not run engine in yet so unsure wot power like. they any good?

[Stuart]

I trust you had the manifold face skimmed to ensure they are flat? Thats about the "only" issue most had with the Mvaux stuff.

[Philsutton]

What ever you do dont get a ebay one, mine last one full boost run before turning itself inside out. A garrett one might be twice the price but at least it will work.

A T35 will be very over kill for 300bhp, a t34 should be able to do 350ish depending on which one.

[tony k]

i was looking at the t34 looking around at some prices wheres a good place to get one

[Rick Draper]

Go to precision turbos or somewhere like that in the USA.
