A TD05 front entry should be available fully rebuilt for around £500.
Donor turbo £150 - £200
Service kit £ 100
Front cover £ 100
Labour £ 100

Typical spool up point for 1 bar boost is 2800-3200 rpm dependant on up-pipe, headers, downpipe, exhaust system, induction and mapping.

John Banks found his TD05 was spooling before 3000 on his MY99 UK. I found the same on my MY95 WRX.

Anyone I know that has recently changed from a VF turbo to a TD05 has been impressed by the results both in terms of reduced lag and power delivery.

I had a few for sale but they've been snapped up I'm afraid !!

A TD04 hybrid is another good option but unlikely to be any cheaper or more effective.

And is the rebuild only to straight or also to hybrid?

And what are the prices off a td05 'cause i assume i have to give an td05 first

Download DD road dyno and then load and compare the two curves from Steve Done's hybrid TD04/manifold and my TD05/OEM manifold. Both have had massive effort on the mapping, mine was also running quite a lot of octane booster, but you can see that the low down torque on the TD05 is excellent. Very easy car indeed to launch.

Note that the dyno plot featured for my car has a considerably higher weight because I had a 95kg passenger and 25kg ICE. I have a plot with just me with basically the same weight as Steve's car and the curve is about the same. There may be a small benefit off boost from the OEM ported manifold and less restrictive turbine housing, even if the difference is false, the TD05 on a car does not make it a slug below 3000 RPM is the main conclusion to be drawn. I would say (although have not measured) that the TD04 hybrid from 2000-2500 is better on the same car, possibly similar from 2500-3000 RPM. After 3000 RPM there is absolutely no doubt even if you keep the TD05 boost down to control surge (by down I am talking 19 PSI )

Andy - just noticed the reason for the disparity between the speed in gear of DD vs AP22 - DD uses a 7100 RPM limit for its calculations, although I would normally lift off by 6900 RPM since it has already made power. This does not affect the figures, just it states a maximum theoretical speed possible in gear with this rev limit.

Stan, if he was to change to the H&S downpipe, he would have even more power. I swapped from a T75 to a H&S (at the time it was the scoobysport downpipe) and recieved some more power.

Andy, why fit 2, I already have 2 turbos'! Guess I'll just have to settle with you being slower than me.

David, I have a TD04L hybrid from Mark (R19KET) of Lateral Performance. It was £500 as an exchange item, on John Banks' recommendation, and I am delighted with it. Please forgive the contradiction here, but I am so delighted with it that I shall be changing it for a TD05 (and a few more bits ) when funds allow. If you get one, you will understand I love it.

If you are really after 'only' 300bhp, the TD04L hybrid will deliver it, and as John says, should pull more strongly and smoothly from around the 2,500rpm region. Compared to the standard turbo, you will have a nice big There is more power everywhere and no more lag that I can detect.

But I think you will struggle to get 300bhp without giving the turbo a little help. I have a full decat exhaust, Scoobysport equal-ish length headers, and big top-mount inter-cooler to go with JB's Tek3 remap. John reckons I'm at about 310bhp. Fuel pump is standard and KnockLink is quiet as a mouse.

Others will know better, but I would say without a bigger TMIC and equal-length headers, you'll top out around 280-290 bhp. And you'll have to ditch the stock exhaust for sure.

Richard.

Danny, I was not talking about anything other than Hoppy's figures, on an ECU I mapped, and was actually thinking nothing towards MD vs TD! He pressed me for a guess at power figures and quotes what we worked out as possible based on some others cars... BUT I think it is optimistic, and the best possible he could ever hope for on present spec. I wouldn't want him to be disappointed and not get his 310 BHP, and I acutally suspect he wouldn't. Steve Done just breached 300, but not every time at the rollers. Thing is when cars on smaller turbos and standard intercoolers have had over 290, it could do. But the average of well setup TD04 cars at PE is probably more like 270 BHP, so the hybrid with headers and FMIC might do 290-300. That's all I was getting at not digging at anyone! Honestly. The whole TD/MD thing is behind us now I think and things are moving on.

Yes RR do vary, but I think a lot of us are questioning just how we can tell a 10% difference between cars without going to an engine dyno which is still subject to issues!
