Don't get your knickers in a twist, the point Hyperluxa was making is that your casual, arbitrary, unsubstantiated and in essence provably incorrect dig at Forced Performance products is miles off the mark.
People who may have only been on here a year, may be influenced by what you have implied and then miss out on some provably fantastic kit, based simply on an off the cuff an "uninformed" comment like that.
I know for a fact that Hyperluxa knows intimately, and in a degree of depth that would simply stun you what he is talking about. Even I wouldn't argue with him on this point, (and that's saying something)
There is masses of evidence to show FP as being at the top of the pile in their area and it's the primary reason that I am an Agent for FP they are routinely copied by other manufacurers and for very good reason.

Some people like the ION turbo's and said they were the best thing since sliced bread, John banks didnt, that's his opinion..
As for saying its uninformed, when / IF

My main problem with forced performance is they woudnt supply a compressor map, nor would they tell me how much air they thought the turbo was capable of flowing, all I got was quarter mile times and dyno plots which really dont excite me! (or didnt then!!)
If people want to buy forced performance turbo's then fine, Ignore what I have posted, as its only a comment.. and Im sure people will do some research before parting with a £1k

Turbo wars will never end. Different setups and different people prefer different things. There is a fine line for exhaust wheel or housing sizing relative to your compressor and this is where a lot of the hybrids can be tricky IMHO. What worked on Harvey's built 2.0 on race fuel did not work well on my stock 2.5 on Optimax with octane booster. Whilst we suspect I got a different turbo to Harvey despite what I asked for, the compressor map may suit a high boost/high revs 2.0 far better, in the same way that a 20G seems to suit a low boost/low rev 2.5 better than maybe it does a 2.0. I did my homework on the iON because of previous disappointments, and greatly irritated Harvey in the process by pressing for details about fuel used etc, but it still didn't help me pick a winner for my setup and preferences in the end. For my 2.5 the 0.82AR GT30R-12 I followed it with was a bit big on the exhaust housing for a stock internals engine.
The hits I've had for killer power band and response have been:
2.0 Scooby with TD05H-16G
2.5 Scooby with TD05H-20G
2.0 Evo with stock TD05H-16G big
Other highlights:
2.0 Scooby with VF28 or VF34
2.0 Scooby with hybrid TD04
Big rotated Garrett on a built engine running silly boost with high octane (of course...)
There still seems no certainty over gearbox choice. drb5, I think you need to watch for feature creep, remember why I sold the car to you... I had no proven options to go to, had held back from built engines after an initial dabble then 2.5 headgasket problems, then I had gearbox isssues.

As for research into (particularly) the FP Green and Red units, the point I was making was that contrary to your casual and unsupported "blow off" of them as products it would have been helpful if you could have intimated WHY you thought they performed so badly?
That would have to go against the grain though based on the consensus and volume of good feedback which is openly available about them?

Already got Gazzasti's Wiseco pistons, new Cometic head gaskets and i'm in the middst of getting some rods and head studs...ok, it isn't an RCM built(or similar) engine, but it should hold together ok for 430ish hp and 400+ torque. Those figures aren't OTT i think and even though maaaaaybe the current v5 sti box, once repaired, would hold together, i'm sure something a bit stronger and a bit newer, wouldn't be a bad choice. I do still have to get a shot of one though. Halleys never got back to me about a test drive.

Does anyone know of someone who has taken a 6 speeder to 500+hp without problems? What's Alan Bell running just now?

Well Andy will be mapping my 2.0L with garret GT3076R at his place with my UK six speed once its all fitted so your welcome to come and have a go in it then.
Would be less of a trek for you too.

drb5,
I would echo John Banks' thoughts re turbo choices, I've recently gone from a 72lbs turbo to a mighty VF35

Yer i see what your saying.
The more i hear and think about gearboxes, the more i don't think it's worth going mega...but then i wonder if strengthening the block is even worth it!![Big Grin](images/smilies/biggrin.gif)
I think some more time and consideration is needed.

Not asking too much of the gearbox, if i DO go for it too.
Enquiry form sent to the clinic as well.

The 53Ibs one that Jerry had (now that you got it), Is a ver of something I order after talking to Paul on what to get.
It's basicly a GT30R in 52trim wheel IF I remember correct, so not true copies In my meaning
![Big Grin](images/smilies/biggrin.gif)
It will do 400/400 on plain optimax with a 4-2-1 headers, and with some better fuel and a 4-1 header I would guess ~430-450 shouldn't be a problem.
Great turbo on a 2.5L

FAO John Banks - Hi John, re your comments on sti 6 speed selector problem between 4th and 5th...did you have a gear crunch problem?
I've got this, going up or down into 5th, only a small crunch and much less or not at all if get the revs about right.

Ah, I see, thanks John.
Not like what I've got...thinking of trying different oil to see if it will allow smooth gear changes when pushing it from 4th to 5th.
Any you recommend?

Is Alan Bell about? I'd just like to confirm if his box crunched all the time or just when booting it and changing into 5th? At less of a throttle usage the gear change into or down to 5th is fine, no crunch - does that still point to synchro?

Nothing at all wrong with a 6sp box in my car and it suits me down to the ground..... it all depends on what you want and what you intend in doing with the car.
Tony,
Sorry mate..... but over 350lbft
Hold on a minute...... there's a pig pink flying. ![Cry2](images/smilies/cry2.gif)

![Question](images/icons/icon5.gif)
Interesting, thanks Alan. Seems mine crunches sometimes and not others - I've currently running 420 ft lb but even gentle changes have made the odd crunch into 5th (this has only happened once or twice though)...It does seem to be giving it large that makes it worse. Is there an easy way to tell if the synchro is duff without strip of the box etc - I still wonder if I'm using the best gearbox oil?
Also, how much did it set you back to fix the synch?

Alan's a big bloke though shaun, and I really think the size of his arms are slowing his gear changes
He's definitely got the lead right foot and corrrect left foot with 1.6 60ft times though
