having gone through a few cheap units and failing, the way to go is a double ball bearing unit now.
the engine is forged and cam'd, plenty of fuel supply and clutch is well specified.
so i'm looking for a 400bhp turbo with minimal lag, but a little more headroom for pub talk figures is preferrable so it's not on the limit.
off what i know and that is little, a GT3071 would be the right area, what housing as i've been running 0.63 ones for the past year.
basically tell me what i need as i'm just at the end of my tether now with this.

cheers

gtx2867 and a new exhaust manifold if your not bothered about much over the 400hp .

 

i will say it before some one else do ,ask your tuner who is mapping it .

 

t38 for cheap reliable power..

 

he is his own tuner...

 

that was another consideration, no need to change manifold, just change flange, no room elsewhere for turbo to go.

i'm my tuner/mapper, that's the challenge really, i know of some gt30's making 415bhp on a similar setup, obviously varies from engine to engine of course.

basically i don't want to go over a grand, even that is pushing towards the divorce courts lol!

 

also, an anyone recommend a place to get one from?
are turbo dynamics any good?
owen developments have been contacted via email to see what they suggest.

 

I have an Owen developments Gt28R billet wheel, race roller bearing etc, it may not quite reach 400bhp though, I'd have to check housings, I'd take a grand for it, that's a bit cheaper than I paid trade

 

hmmm, about a grand is where i'm heading at top whack, is it internally or externally gated?
either way some more detail on housing sizes would be great, with a billet wheel that pretty much makes it a gtx.
400bhp is just a rough estimate, if it pulls low down well then that may well be a good compromise.

 

anyone had a gtx28 turbo yet?
what are they like?
how well do they spool?

this is something i need to get sorted in a week lol!

 

Pm wilky on here dude he can sort you out a monster of a turbo

 

just did that a few mins ago, i hope it can get sorted quickly.
it is literally make or break for this motor, all the cheap temporary parts have been changed now, the misses is going mental i tell thee lol!

 

It's internally gated, not classed as a GTX as its not a genuine Garrett unit, it's one of Owens with there quick spool billet comp wheel.
I've been meaning to return it for a while or sell it on, i can get some pics if you want

 

i'm not too worried about the internal gating as i can work round that easily with a mod to the adaptor i have already.
pics and any more details welcome, i'm working towards a gtx2867r now, how would this compare to one of those?

 

mate your wanting to run 400bhp in a little xr2 lol! it would be insanely fast BUT spin spin spin in the lower gears..i would aim for a lower power like 320ish on a GT28RS turbo.. little less power maybe a little more grip imo

 

spin isn't too bad in the dry with the geometry set how it is and the FRS gearbox with 16's to be honest, i've just been running 1.8BAR through a t3/t4 unit and that didn't hang around (didn't last long either lol!).
400horses isn't unheard of, i'd be happy over 350 to be fair, but i do fancy a top speed run at some point, mk2 xr2 record isn't much over 150mph, if i had the bottle i could improve on that quite a bit.
the right turbo would have minimal lag anyhow, so very useable power.

 

i was surprised at how cheap some of the quotes turbosytems were giving for turbo's and he does all them new fangled billet jobbys (im a t4 big lag lover, good things come to those who wait lol)

 

Ill keep my eye on this as I would like to go either GT3071R with a .82 housing or GTX2867R with a 1.06 housing.

What I want to know is what sort of EGTs and back pressures people are seeing having to run the smaller billet turbos up to make the same power as the bigger none billet items.

 

As you no my zetec made 415hp on a gt30.71 with a .63 exhaust housing

 

Fuck doing over over 150mph in a little tin can

 

it's a laugh, been to 145mph so far and the thing was way too light, on a proper runway is should be more stable.

clarke, my initial thoughts were the gt3071r as that's what you have been running, just been offered one, just need to know spec, also waiting for wilky and a few other places now.

/\ seen that one, with postage and duty, because i always get stung
that'd be Ł1060 ish without an exhaust housing.
been offered a gt28r owen developments one, just need to know more spec on it like exhaust housing, it's been suggested to look at an 0.82 or a 1.04 IIRC
also been offered the gt3071r for Ł650 unused, so tempted by that, although with most of these, i'll need to change flange on manifold but no biggie.

 

the gt3071 is a bargin @Ł650 unused mate ,i'd go with that.

 

i think it is the one to go with, just got to figure how to get the piping in for the 4" anti-surge ported inlet housing now. it's massive, comes with loads of parts though too, just waiting on spec of exhaust housing, 0.63 will ding dang do, cant be any laggier than the t04b or the t3/t4 one i have had fitted.

 

and if its on a t25 flange then you want a 0.82 housing

 

My mk2 has 415 when at 320 it was fun but i new it could be made better lol. That and i couldent get my times down at pod with 320

 

/\ this man has got it in one, why settle for less, i could have dropped the spec of the engine for lower power.
cheers for the heads up gary, just waiting on the finer details now.
owen developments can't get close for anything less than Ł1300, the gt28 i've been offered is only a gt2860rs with a billet wheel, if the wheel was a 68 i'd have gone for it, but will only make 350bhp, enough i know, but no room for improvement really, at least a gt3071r will be good for 450bhp proven.

 

RDT have a crazy sale on Garrett turbos at the minute. Will most likely beat Owen's price by some margin!

 

RDT?
links to website if you please

Just seen it on my news feed and though of this thread haha

 

i've left a message, but i think the costs aren't that great.
i'd be all over a gtx if i had a usable exhaust housing to hand.

 

the lads come back tome on the gt3071r, it's a t25 housing on an ar of 0.64, so probably too small. Ł650 is a good price, but by the time i add a bigger housing into the mix, it's racking up further again.

 

Wanna buy my turbo?

 

funny you should say that wilky said the same and a great price

 

what are you after for it?

 

hmm, seems this is going to be all wrapped up on tuesday, gt3071r t3 0.63 housing on it off clarke, used but a fair price.
so if you want a 350bhp ish turbo, the one i'm not going for is available, but has all you need to get it installed apart from pipework.

 

Woop

 

woop indeed my friend
it should need minimal mods to get in, so happy days at last.

 

Yea txt me tuesday afternoon my flight lands at 2.30 tuesday morning so make sure its the afternoon lol
