19T turbo? - Page 9

carpy · Mar 31st, 2007, 10:23

Bringing this thread back from the dead.........

I've re-read it and due to a temporary tightening of ones wallet strings, the 18T bolted onto the standard DP is now looking like a better option than a 19T and new 3" downpipe.

What's involved with replacing my 16T with an 18T, and what kind of power gain would be estimated? Would a custom remap be required? What kind of cost including fitting?

Anywhere good that offers this near London (I'm West but can travel).

Many thanks

what have you done to the car so far? what mods does it have allready?

Hi Bobcat

The car has a RICA 280 remap, ITG air filter, strut brace & Miltek cat-back.

Would the 18T be a good choice?

I think it would be a great idea, especially if you're willing to spring for the custom map.

cheers

I was under the impression that it was dangerous to try and run an uprated turbo without getting a remap to take it into account. Is this not true for an 18T then?

foggyjames · Mar 31st, 2007, 22:02

Well I've never observed air/fuel ratio and ping threshold data on a T5 running hardware it's not mapped for, so I don't know exactly how it behaves. Plenty of people do it with T5s. 940s cope ok, up to a point...but it's not ideal. Some fuel systems do a remarkable job of coping with alterations...some (generally 80s systems) are useless, and no power is added.

Most likely, it'll be safe enough, but you'll not be getting the most out of the hardware.

cheers

I'm with you. The main reason for getting a new turbo is to increase the performance, so really a custom remap is a must.

Anyone know the best place for a custom remap after I've had the 18T fitted?

foggyjames · Mar 31st, 2007, 23:56

In terms of people I know to do custom mapping of the standard EMS...
I think there's not a lot in it RICA vs MTE - other than that the MTE stuff is a little more realistic in its 'forecast' of numbers. Stuart (i.e. SW Autos) is fairly new in the 'chipping' game, so it's perhaps a little early to make a long-term assessment, but his cars seem to be getting good numbers, and other work has an excellent reputation. I have no reason to doubt that his work won't be holding up to scrutiny in 18 months time.

Ultimately, I'd happily spend money with any of the above, but most people's choice seems to come down to who you know/trust/have had work from before, and who is nearest!

cheers

Yes it's going to be either RT mechanics and SW Autos, but ideally I'd like to know what kind of power increases the 18T would give over my standard 16T (130,000 miles on).

Also what about modifying an 18T to give more power than standard. This sounds like a good plan as it wouldn't require a DP change.

Saying that though if a 19T or similar, and a 3" DP give much more power than even a modded 18T, then it would kinda be a false economy to try and save money by going the 18T route.

foggyjames · Apr 2nd, 2007, 00:32

The DP is good for some power, but it seems the 19T isn't worth much over the 18T. For the extra money a 19T + DP costs, I'd go bigger than a 19T if you want more than an 18T can give, if you get me. If you specifically want the insta-spool appeal of the TD04 series, but the ultimate incarnation thereof, the 19T + 3" DP is certainly a great combination.

Serious benchracing time? It depends on whose dyno you're using. If a standard chipped T5 makes say 270 on a certain dyno, I'd expect to see 280-290 with an 18T, intercooler, 3" exhaust from the bottom of the DP, remap. Perhaps a shade more...it depends on how accurate the reports are re: 18T vs 19T, and how much of a hold up the stock downpipe is on a T5.

cheers
