Can fully understand this... definitely the way I feel about the car in the rain (though wheel spin in 3rd is funny). I can't stress enough, that anyone pushing their cars into these bhp figures needs to spend some serious time getting used to the car AWAY from people. If you do this level of mod find a nice straight road in the rain and plant your foot and prepare to put on fresh underwear. My worst nightmare is someone doing this level of mod and planting their foot while in the middle of a bend. I imagine in your case, you don't need to wait for the rain.:lol1:

Graham - I would definitely say that I am happy sitting at my current power level and I can definitely see why you wouldnt want to push the limit much further. From your perspective with your competition against your EVO 'enemy' and considering your suspension changes, I would think you would be very happy in the 400 to 450 region.:D

That was the conclusion I came to on the Snet '2.33' thread (bloody good debate that was, just as this is).

To be fighting the car in adverse conditions will slow you down.

This year at a very wet Hillclimb I nearly took FTD in the Sti as the car was so good in the wet, barely loosing traction over dry conditions so I could push it very hard that run. That was 380 x 360.
Others were on wet slicks and in single seaters etc.

Would love to hill climb a wagon, even if just once, just to see the look on peoples faces :D :D

lol. This brought back a little memory when i demonstrated the car when it had the GT30R on it.. We floored it in 3rd cause there was no point in flooring it in 2nd gear, but each time we floored it, the car would light up the four wheels and slide nicely over to the right hand side of the road as if i was moving over to overtake a car. The passenger thought i was steering it over to the side until he realised i wasn't doing anything... :D. Needless to say, further acceleration demonstrations were feathered on the throttle. The comment from the passenger at the time was that i was certifiable. :D Good case for traction control to take away that task. :)

Just can't do it imo, unless you have several thousand pounds worth of fancy suspension to harness the power and even then, i'm not sure if you could totally eradicate it. Doesn't help running tyres which are only 215mm wide... Not a lot of footprint.

swisstonihasher 14 November 2006 09:42 AM

Alan, "or is just that there's a wall of torque in mid range that top end feels flat in comparison?" is correct m8...although below 2500 has nowt at all, she coughs and farts because of the cams, it doesn't matter...the surge from over 2500 and a massive wall of torque makes up for it, I've not found I've been stuck in the boggy area at all, maybe at worse just need to drop a gear. Although it would be nice to have pull from 2000, I really dont miss it and yes I can easily go over 6000 revs but that's not the way I drive (being ex mechanical engineer, I dont like red line area) - she does drop off torque a little but there's plenty enough of a power band to go balls out in every gear and not bog down at all, not like the 400 bhp evo 8 as seen on Top Gear - I've never yet been caught like that on twisty roads.:thumb:

AC-scoobie 14 November 2006 12:48 PM

Great thread, i've been toying with the idea of the 2.5L. As a few have mentioned 350/350 would be ideal for me. The question I have is could you do this by keeping the TDO4? Or is a new turbo a must?

swisstonihasher 14 November 2006 12:55 PM

I dont think you'll find a TD04 will give you enough flow for a 2.5L or at least you'll have the 6000 revs and no further drive problem...spool on it will be blo*dy quick though I guess.

Neilo 14 November 2006 12:57 PM

the TD04 is far too small to give you much power above about 4500 i reckon.

it would spool stupidly quick though i think youd have near full boost by about 1800!! maybe less...but you still wouldnt get much power out of it as the turbo wont physically be able to shift enough air to fill the engine at higher RPM.....

AC-scoobie 14 November 2006 01:12 PM

Thanks for the reply guys :thumb:

More saving required :)

Agree, though that just starts the purist vs performance argument. I'm sure Andy mentioned some aftermarket options on this topic but I can't remember if he felt they were worthwhile. My next mods are all about reliability and improved spool up. It will be interesting to see what, if anything, works. With the GT35R have you found anything you felt provided tangible benefits in terms of spool up?

I've been looking at the T25 suspension from Powerstation. I know Graham (911) raves about them and his project has been very interesting but forking out 1400+VAT is a pretty big commitment without having a go in someone elses car. As always the chase to power occurs before the chase to handling (in my experience :D). Of course the worst thing that could happen is the suspension is so good I can floor the car all the time and have to chase more power:D :D :D :norty: .

*smiles* - so have you bought the doggy seatbelts I see advertised?

*smiles* 14 November 2006 07:40 PM

I have the doggy guard, which is the first addition any wagoner must make :lol1: :lol1:

911 14 November 2006 08:19 PM

Always do the Chassis first, then the engine.

Mistake i made was to buy cheap coil-overs that proved to be very poor quality (AVO's).
Coil-overs should not be the first thing to buy imho, but a good set will be great when you are ready.

A good alignment technician is akin to a good mapper for the engine!

Graham

ps: blag yourself a ride/drive in the Litchfield Type C as i did and you will see why you fit AST's @ £1400.

Nope, what you will infact end up doing is seeing how inadequate a classic chassis (sp?) is compared to a newage chasis with AST suspension, it will NOT give you any idea as to how a classic will perform with AST's on.

*smiles* 14 November 2006 08:55 PM

Tried one of those type, they got sll caught up and nearly strangled themselves.

*smiles* 14 November 2006 08:58 PM

"...but doesn't restrict your dog from sitting, turning or lying down on the car seat.."

Thats the problem, the dog moves around and gets all tangled up in seatbelt and harness, trussed up like a maypole and have to pull the cra over and spend twenty minutes trying to free dog from harness and seat belt. :nono: :nono:

If you were realy strapped for cash could'nt you use a good low milage legacy 2.5 bottom end ?

911 14 November 2006 10:46 PM

Allow me one more 'stray' please.
About the AST's:

That day I tried the Type C I drove 80 miles on the road to a hillclimb (Prescott, 4 miles from Powerstation).
Raced (or rather practiced) on the track 2 times and then nipped down to PS with the EVO Driver (in his EVO..another story).

Went out in the black Type C with AST's and the power conversion they do.

I was encouraged by Ian to pedal it hard. I did as i was still in race mode (even still had my race suit on).
I am confident I compared the classic to the Type C as I was so surprised how similar they are on the road.
The AST's can transform the cars. I'm sure that other quality systems can too before some jump at me!
The Type C's most striking features for me was the twin scroll engine and the 6 speed box, light years ahead of my golden oldie 2 litre.

The ride back in the EVO RS was another revelation (Ohlins 2 ways and 550bhp)

What a car.
No more suspension from me now...

Graham.

DesR 14 November 2006 11:38 PM

OK... back on topic then... whats the cheapest 350/350 build for *smiles* using a new 2.5 engine. I never tried to build the 2.5 to this level so havent investigated the type of spec needed but off hand would suggest something like:

TD05-16/18G (or maybe a fancy twin scoll?) - £800
2.5 engine obviously - £1600 including gaskets
remap - variable but at least £500
FPR - £80-ish (didnt see this on *smiles* car spec sheet)
2" DEI wrap - £60
engine oil - (people always forget this) - up to £50-ish

Total +-£3200

Did I miss anything?

Exceeds your original budget of £2K but I'd expect you wont be disappointed:D . You are planning to do the spanner work yourself? Anyone want to correct me or my budget?

DesR 14 November 2006 11:43 PM

Would love to learn to do the spanner stuff, but sadly dont have the facilities to do it myself, plus work commitments mean it would never get done any time soon :( :(

I didn't change to the GT35R to gain any benefit in terms of spool up, it was changed to allow peak torque to be produced higher up in rpm than the GT30R and an increase in top end power.
