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

[Wilko]

With an 18g my 550's are maxed out at 3bar fuel pressure, so 440's at 4 bar will be beyond their limits. I'm going 4 bar when I can get hold of my mapper.

Clocking the turbo is easy, but get whoever fits it to do it, and then the bosses for the actuator need cutting off, and rewelding.

this seems to make sense,i could never understand how 440's could supply 380bhp worth of fuel,easy answer they don't,i remember 430's on mr2 turbo running out of puff at 320bhp and 540's being good for 370bhp. The evo comes with 560's though.

i will be fitting it my self so how would i clock it

mrc....i can say bad about them mate! done a terrible job of mapping my k04 ibiza

 

[ryan_s3]

lets hear some details then. I've never used them but i've heard good things

They can it has been done,it's not ideal to run injectors at high pressure and duty cycle mind.

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 did research and I did actual fitment... and run a different setup.
In the context OF THIS THREAD, the guys got a JS mani, and an expired VF34.
Comparing hotsides from EVO's on twin scroll is completely irrelevant.. might as well talk external gated whilst your at it.. its that different.
Owens offer more than the 2 versions on their website I believe of their particular hybrid.
If this guys looking for something else, and still has stock internals, then he will be in the danger zone from anything bigger. 18g might well suit his wants, but I would'nt fit one on stock internals personally. foolhardy

Its a reasonable step change to push past 400bhp yes, and an even bigger one when your closer to 600bhp believe me

 

[ryan_s3]

I thought your swapped the pe1820f for a td06 20g/fp green ?
Anyway in context of this thread,the guys not getting a vf34 off jabba so he needs a replacement.I guess the cheapest option is too buy another for £700 and chuck it on and it will need clocking. Personally if i was to do it again i wouldn't use a vf34 i would use a 18g,you could run it at lower boost until funds were available for rods/valves because as we should all know you always want more!It's also rebuilable with a 20g wheel etc.If your happy with what you have then stick with the vf34.

What on earth runs this setup?

jbs blurb;

The JBS IHI Stage 2 turbo conversion uses a custom developed JBS hybrid IHI hot-side combined with the cold-side of a GT30, offering the Garrett turbo power yet with the good old IHI turbo spool!

 

[ibizacupra]

thats a good option for him, just needs to be able to get the 18g modded to fit etc, and mapping checked and tweeked as req'd

lmao.... aka FP Green Spec, superzilla, which is nothing to do with an IHI aside from sharing the flange style.

and how do I know? I supplied it.

i knew it wasn't a ihi exhaust housing just by looking at it,but i thought i'd see what you would say!

lol-yea right

 

[ryan_s3]

lol.just look at the picture

 

[barnsley]

does anyone know what the most power i can run on a small port head as im now thinking about doing the internals

 

[ryan_s3]

plenty but you will make more with a largeport.

 

[barnsley]

am i right in saying large port is vvt or can i just use my cam set up

 

[ryan_s3]

nope all largeport are non vvt,cams depend on what you bhp goal is.

 

[barnsley]

not sure on how much bhp im wanting need to see how much funds i can get and need to buy a cheap run about

 

[JAY DE]

So guys if he bought an 18g and run it at 340 bhp what kinda boost will it be running..? 1.0bar maybe
