When i said it will bolt up i mean it will fit the jabba manifold and i did point out that there would be some fitment issues due to the larger compressor housing.I have no idea what wilko or caney run these days.
Seems as though my own big 16g with 10.5cm hotside would not be too your liking then?



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?
:p

10.5cm hotside??? wtf...
your kidding right? thru a JS mani which is less than 52mm outlet port size...

Your talking EVO tho now yes?

i guess i can't compare evo stuff to vag stuff ,but i'm sure the jbs twin scroll stuff are just evo turbos as the manifold seems to reflect that. The e9 turbo runs a big 16g comp wheel,10.5cm hotside and large td06 compressor housing 420bhp potential on the stock e9. The 18g runs the same size comp ex and slightly bigger in the same hot side turbine in/ex but smaller 8cm housing.

my opinions of the owens ihi/gt30 is that it's a total mismatch and i can only think of one word lag. It will be very similar to a pe1820f but worse,tiny hotside and massive compressor wheel.

The 18G on mine fits fine on the jabba manifold. Some minor grinding of the head casting and block casting was necessary to fit. It hold 1/2 bar more boost at the limiter than the vf34p20 did. Shifts nearer 300g/s of air verses <250g/s on a vf34. Spools quicker than my 34 ever did.

Caneys on td0520g, and tells me when it's running well is like his vf34 on nos. Still has some teething troubles though.

These turbos are much easier to fit if you make a 5mm stainless spacer to go between the manifold and turbo. No clearance issues then.
Oil feed line needs changing, and you may as well change the horrible water feed arrangement jabba supply.

I don't think any of the big turbo suppliers will give you a cast iron warranty, as there's always a number of excuses they can use, and at the end of the day you're taking the piss with these boost pressures >1.5 bar on normal fuel.

IHI's are fragile little turbos. I've killed 4, R1gti has killed 3, dan killed more.

I figured a decent 18g would produce 40-50bhp more than a vf34 nice to hear that it does wilko.
20g possibly too big a compressor wheel for the small exhaust turbine/housing but alot better than a vf34 hotside and a gt30 compressor.

I wouldn't bother going for a bigger turbo unless you can get it mapped.

The owens turbo spools well on the 2l...
BUT MY AUDI IS STILL NOT MAPPED.(I may be braking it soon as the tax will be up again so if anyone fances a 2l 20v let me know)

I got mine from blouch turbo in the states. Stealth racing sourcd the fittings.
Mapped by someone who works for a tuning company that doesn't offer custom mapping.:whistle:

Mrc seem to have been able to map Caneys at 2 bar using an rs4 maf. Boost has to come in slowly, as as ryan says big compresser on small turbine, the 20G is prone to surge.

Dan. You could try MRC, or go stand alone and take the bulbs out of the lights on your dash.

You exactly right your not comparing like for like remotely ryan.. :rolleyes:
EVO aint Scooby fitment turbo's (thread being IHI, Jabba VF34 died remember)

This guys running JS mani, VF34 setup, so what the point in talking EVo setups and twin scrolls?? :confused:

Have you driven a PE? laggy? not...
GT30R on 0.63 housing is as quick spooling as the PE1820 was, but had much stronger sustained top end.. Tims ibiza would drive by mine on a lot lower boost and neat idential spool on track.

Kevins Leon racecar runs the owen Gt30/ihi hybrid, running a reported 440bhp on owens rollers. He's not running big boost so far as I know either. (~1.5bar)

If you think a PE1820 has a massive compressor??? LOL It aint.
Its still small, as is its tiny turbine and housing.

if you look at a 62lb and 65lb comp wheel, you will soon realise what small is and what medium size looks like... :)

so if i went for an 18g would it just be oil feed and coolant piping and mapping i need to sort i can use my exhaust and will my 440 injectors be ok for fueling will my inlet piping need to be bigger

clocking it? (rotating)
remounting actuator brkt?

fueling should be ok, maybe consider 4bar fpr if not already on one, and also fuel pump, again if not already running a higher output one

18g does'nt sound like a huge leap.
only know of wilko running one for a few months now.

or another one>> http://cgi.ebay.co.uk/IHI-VF34-Ball...ryZ43120QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

for £435+carriage (£25) and start again as is.

hey bill lets not fall out over this mate,i did hours of research on a upgraded turbo when i had my vf34/1.8t. Everything pointed to a 18g being alot better option than the vf34,it's rebuilable/upgradable for a start and in my opinion alot stronger turbo.There's guys running a real 380bhp on scoobies at 1.4bar on the spec 18g i quoted.Lets face it 340bhp is a absolute top figure for a vf34 running lots of boost,as a alternative a 18g will do 40-50bhp more thats why i recommend it .

Could you explain why i can't compare evo 2.0 vs 1.8t? other than the twin scroll which helps spool but would not affect peak power? I would have thought a scooby engine is more unlike a straight 4 evo/1.8t engine.
Your telling me that the jbs kit is not a evo 9 turbo/evo fp green?

i know the compressor wheel on a pe1820 is 70mm which is not alot bigger than a big 16g/18g 68mm but the the pe has the tiny hotside of a vf34 i would say your car was running a real 360/370bhp when you had it on.

Tim was running a decent manifold, ie not jabba. A evo will spool a gt3076r (gt30r) alot quicker than a 1.8t and i've been in a 520bhp one with a proper set-up and i wouldn't describe the spool as anywhere near vf34/pe1820f but then again i wouldn't descibe the performance as near a vf34.

Interested to know more about this owens gt/ihi hybrid ,owens themselves quote 405bhp/355lb/t at 1.7 bar and full boost around 3500rpm for the smaller turbo but i doubt this would be suitable for standard piston/rodded 1.8t's lets face it we have been going round thinking we have 350-380bhp when we have 320-340bhp and it's a big jump to 400+

You would have to convert back to cable driven throttle cable to run most stand alones other than the motecs and there £££'s. Standard ecu seems to do the trick on bills but whether jbs would touch it is another matter.Try MRC mate have heard nothing but good things.
