My Ihi Turbo Is Dead !! Help With New Turbo Please

[barnsley]

hi i have a leon with jabba ihi fitted the turbo when last night no boost and loads of oil smoke out of the exhaust

do i just fit a new ihi vf34 or do fit some scat rods and go BIGGER with the turbo

THANKS ALL

 

[Craig!]

Bigger... my engine and turbo's fooked and it looks like im going bigger or back to standard and sell on.

I'd go with a 18g,depends whether jabba can/will map it for you.Other option is owens ihi/gt30 hybrid.Is it under warranty?do you have standard internal?what boost were you running?

 

[lofer]

I'd ring jabba first thing Monday! I've always found them extremely helpful

whats an 18g im a bit thick phoned jabba no warranty not sure if im taking it back there im on std internals 1.3 bar boost small port auq engine

 

[ryan_s3]

I wouldn't have thought it should have failed running 1.3 bar.Mine did 10k at 1.6bar no problem. a 18g is a mhi td05h 18g they come in all sorts of forms but i'd try and go for one with a 8cm exhaust housing and larger td06 compressor cover if it will fit.
MRC would be my first choice.

 

[barnsley]

will that bolt stright on or req some mods ie exhaust manifold down pipe whos MRC

 

[ryan_s3]

Will bolt straight on,just make sure of clearance with the bigger compressor housing.
MRC are a company, www.mrctuning.com

 

[ibizacupra]

you 100% sure that combo "will bolt straight on" Ryan?

you seen it actually done?
8cm housing? TD06 wheel?????

what compressor housing..
its mighty tight down there.

Another IHI bites the dust.
why no warranty? how longs it been fitted then? (by them?)

or

not a chance of these comp housings fitting Jabbasport manifold.

 

[barnsley]

was fitted by jabba 2000 mile ago befor i got the car was told warranty is with the person that payed the bill

 

[ryan_s3]

You can get a small td06 compressor housing,the 8cm is the exhaust housing and it will bolt up directly to the standard manifold,the only issue is that it might just foul as we have seen with dan-ish proper td06.Personally i think the vf34 is a small turbo capable of 340bhp maximum.A proper 18g will do 380bhp no problem.

sounds like a get-out clause!

oddly enough i do know what an 8cm housing is... I do have one after all. lol
pointless however and ill sized on a small comp wheel... but what do I know eh?


VF34 have been fine except for when customers get over zealous with their ambitions on what it will make... much to do with people on forums and the power claims... but not so many speak up when its all gone pete tong... How weird is that tho eh?
Many VF34's have expired is the reality.

How has wilko's 18G got on... not ever seen any figures off it.. or Caneys? whats he running these days?

Owens would be my choice for hybrid if someone asked me today for a 400bhp level unit on cast manifold like JS.

 

[barnsley]

bill is that the ihi/gt30 hybrid on owens will i have to mod much what would you do . not sure what to do thinking about buying a kit from jbs but not sure which one as im small port

 

[Craig!]

Mine might have expired after 2000 miles too but this looks like a valve will have caused the damage (if there is damage yet to check). I however was running 1.5 bar but it was no where near as hard mapping as the likes of Jools (custardcupra) as his with the P20 still spooled well mine always felt laggy.

As soon as I've stripped mine down there will be a 'looks whats failed' thread to warn people, and I really wished I'd seen Bill's thread regarding fitting a £375.00 set of one piece valves before going IHI. When I spoke to Jabba regarding internals I was told not to worry or waste my money, and there would be no problems on the standard valves... oops.

If my VF34 P20 is dead I'll be looking into the likes of the above mentioned, but untill I actually know whats wrong I can't comment too much. Need to find out what is wrong before throwing away £££.

I'm undecided on mapping, if Mike will map another turbo fair play, if not I'll need to find somewhere willing to do it.

 

[ibizacupra]

owens have a few versions of that turbo in various trims etc. given a call and discuss.
hotside and DP should be ok, but not sure about oil/water lines to it.. Dan can comment as he's fitted one.
you do have to trim a piece of the head casting to allow it to sit righ on the manifold.
EGTs are critical on these for reliable operation, so whoever tunes it afterwards should bare this in mind.
The leon combe saloon i race against runs the owens turbo, previously PE1820 like mine, and has made 440bhp on owens rollers. it has had wastegate actuator seizure like my FPs have had, but thats its positioning in 1.8t engine bay (transverse) and its "cooking" temps.
The 18G's mentioned are worth considering, but you should work up a package with whoever you wish to tune the car with and consider some tweeks during fitting will inevitably be req'd..... as opposed "it just bolts on"
Mark Harrison @ Owens is who I have spoken with (race against) - top bloke with some very good advise.

thanks bill
do you have a web address or phone number

you might wanna check with jools/custard on how theirs are currently running

If JS have advised not to bother with valves, thats surprising to me, as we both know what happens on more than a few tuned 1.8t's. Thats why uprated valves got brought into the equation at all, BECAUSE of KNOWN FAILURES. I started the change to uprated valves supplying them initially. Its an investment at the end of the day vs risk if you dont. (much like rods... do i dont i type question)

Fueling and top end egt's is where some of the "tuners" vary their opinions on how to map cars. I know CC mapping is less than ideal on my own for absolute power on afr's compared to mikes mapping, but egt's are lower from the extra fuel dumping. The thing is, unless you have gauging to see whats going on, you will be oblivious until things go wrong mechanically in a big way.
Ignorence is'nt neccessarily bliss. Thats a big reason I fitted zeitronix way back when... as I had had enough of not knowing whats going on, in real world/track use, and repeated heat related failures. (never bearings tho)
