Toasted turbos?


Stuliet

Recommended Posts

Over the past few weeks I have been getting an increasing amount of smoke from my Supra, and had booked it in to be looked at in a couple of weeks.

 

Today on the way to work, I got a LOT of smoke and a whine whenever I accelerate. I am assuming the worst, and the turbos have expired. I am taking the car to ToyotaGT later this week for an official diagnosis, but I have limited expectations.

 

So, what are my options? It is a UK car with Hybrid turbos. I do not have unlimited £££ so I guess my choices are either to return to standard UK turbos or get replacement Hybrids.

 

Any opinions?

I have been mulling over options and after a chat with James at ToyotaGT I am considering going to a small single. I am thinking of the PHR Stage 1 Single Turbo Kit.

 

Bearing in mind I have a UK spec, so bigger injectors, etc are there any other essential mods for reliability? I am not interested in creating a beast of a car, but it is a keeper so I am happy to upgrade parts over time as £ permit.

If you have limited funds and dont want to get yourself in too deep I would not be thinking of going to a single set up, I would look for a set of replacment hybrids or stock twins IMO

I am looking to make this a 'project' car for me and intend to keep it for a while so am happy to spend on it. The blown turbos are bringing my plans forward a little, but I don't really want to spend a lot of £ on a path with limited future proof for upgrades.

 

I guess I am looking for a 'value for money' replacement with scope, rather than a 'cheap' option. :shrug:

To do a single conversion 'properly' you'd be looking at £8K+

After a bit more investigation, I have found this thread that shows what various people would recommend in terms of a minimum spec to go single;

 

http://www.mkivsupra.net/vbb/showthread.php?t=71083

 

So, I have the following list of parts as my minimum;

 

PHR Stage 1 kit

New SMIC (maybe part of the NIC group buy)

AEM ECU

FPR

Auto cooler

Engine oil cooler

Gauges - Note sure what I need but am thinking AFR and EGT.

 

Plus fitting and also RR mapping once complete.

 

Given I already have UK brakes and H&R Coilover suspension, I am hoping no further chassis changes are needed.

 

Anything else that I need?

All my opinion of course

transmission £2-3,000

injectors - flow tested and fitted 550's minimum

cams

makes sure brakes, suspension etc is up to the power and replace worn stock parts....pumps, radiator etc

and budget at least 2k for your standalone setup as there will always be niggles

AEM wideband, boost gauge essential

depending on power levels I would prob opt for a built engine as well if over 500bhp and your planning on running high boost

 

so thats another 4-5k to add to your list :( this is all in my opinion so not essential if you dont want to do it.

 

im just a firm believer in doing things thoroughly first time round and not cutting corners as you will only have problems further down the line
