Hi,

the GT30 Billet is the best rotated all rounder.

If you are not chasing big numbers its far more useful as the spool is 2nd to none, alltough I mention big numbers, we have many GT30 Billets out there running over 600 BHP so not to be sniffed at.

Would be interesting to see one on a strengthened 2.5, now what blocks have we got in the cupboards.

kev if you need a test car to try a strengthened 2.5 on then you more than welcome to borrow mine,,,,,,,,,





ok well it was worth a try lol

without me reading through 106 pages of this could you please help me here,i want 500bhp or just over out of my 2.1 would any of your direct fit turbo,s be sutable with good results? o and must be pump fuel no meth,thanks for your time

Wondered when you were going to get that car on the road and run in.

500bhp is a fantastic result. Interesting comparison between the twin scroll and single scroll SC46. The twin has produced more power, but less toque than the single scrolls seem to. I would guess that any difference in spool is nominal. Although trying to get a like for like comparision is bloody hard!

Will try and get mine on the APi rollers when I'm next up there! I can only offer my Delta Dyno run (which was done at 1.2k miles on the new engine) as a comparison for what it's worth!



Enjoy it mate!

I'd be interested to see a back to back of a billet 30 vs a billet 35 on the exact same motor.
I currently have. Stock 35r and a billet 30 is tempting, lol

Hi,

our direct fit SC46 would get you near with amazing spool.

If you are number chasing then go for the SC54 billet, you will loose spool but it will get you over 500 on V power.

One thing to remember though big numbers are not everything, a lower BHP figure with better spool can result in a quicker car, especially a road car.

thanks for your reply,i currently run an rcm 450,what gains/bhp could i exspect to see from the sc46? why would the sc54 not be ideal? lag? boosting late? what about your sc50? thanks again

Spool with sc46 over RCM450. Perhaps, i stress, perhaps a bhp increase. SC54 would be laggier than SC46 and SC50 obviously but should see you on/over your target on v-power. SC50 would be pretty close to your target i should think

Can a std gt35r still be converted to xtr billet spec and how much/time?

Hammer man

iTrader: (25)

Cheers Paul.
Its been on the road for a few months now, but only recently run in and put on the rollers at API. The results are "interesting". I thought it may of had more torque and less power, but hay, what do I know.

TH3_5T1G

iTrader: (15)

Wow, first post since you joined in Feb 2003

I don't think they can be converted. I asked before and it seems as though it is not possible unfortunately

Supercharged

It was stated previously in the thread that they could be converted just waiting on scoobyclinic to confirm.thanks.

The Gaffer

Hi,

they can be upgraded but we are not offering the service at present as we cannot keep up with demand for brand new billet wheeled turbos let alone up grading non billet ones.

Sorry.

cheers

Kev, Any peak BHP figures from a 2.0 litre running a sc46?

TH3_5T1G

iTrader: (15)

Wow, i really thought you didn't carry out this service

Obviously you can't carry it out as of yet but how much does it usually cost? Have there been any comparisons of one carried out of a before and after?

Would the turbo have to be one that was previously supplied by you in orderto be billet-ized?

Check leeroy's graphs back in the thread (read from around page #90 IIRC).

Around 430 on V-P only, and 460 on 16.6% meth.

birchy2010

iTrader: (12)

Leeroy's are held back as he's not running a full strength 6 speed box as i'd seen those previously. Struggling to find anything that is full on see what it can do on a 2 litre

joz8968

iTrader: (13)

Yeah, sure.

Also, leeroy ups to 20% meth then even more gains to had -- near 500bhp I reckon! Because Glenn's smaller SC42 went from 451 @ 16.6% to 475 @ 20%!! (And his - too! - was 'held back' due to a 5sp.). :thumb

Just interested to know round about figures, Moved from TMIC to FMIC and been mapped @ 20%Meth Monday so interested to know roundabout figures before it goes on the rollers ASAP to find out. Might have to try and get it somewhere later this week. Seems no one has pushed it on the 2 litres

joz8968

iTrader: (13)

Will you be getting mapped on 20% meth then I take it (or on at least one map if running Simtek, etc.), and getting the mapper to max out the 46 for all it's worth?

I'm gonna go out on a limb and say you'll get 499.9. Seriously I expect, the bracket will end up in the 480-500 area.

birchy2010

iTrader: (12)

Yep that the plan anyway. Went to see the car this morning and all the FMIC and FPR was on, Just needed the bumper cutting and some fuel seals sorting as it was a first fitment. One map for just v-power then a second for the meth mix.
Here's hoping it can make those sort of figures anyway!

joz8968

iTrader: (13)

Well, if you have a 'lucky' engine/mods set-up, then every chance, mate.

But as you know, even "on-the-face-of-it" identical cars, can end up making signficantly different numbers...

birchy2010

iTrader: (12)

Thats the things, I've done pretty much everything i can to help it so far, was amazing on the top mount at somewhere just over 400 @ 1.5 bar and full boost below 4000rpm. Just a waiting game now and faith it will do it

Ok thats a bit disappointing , couple of other options available if you don't want my hard earned!

The turbo is more than capable of fullfilling your expectations and that wont be a an area for concern,its the car its fitted too with all the correctly matched supporting mods on that car that makes all the difference to the outcome.

Nope, JDM big porters with the AVCS enabled controlled via the simtek

What's your full spec mate and what power did you get on the tmic exactly ?
