TD05 from Early WRX to Legacy Turbo

Post by FrmRgz2Rchz »

I have a 93 us spec legacy turbo and I was thinking about upgrading my turbo. I know the td05 creates low end lag, but that doesn't bother me. I just want to know if the early wrx td05 turbo is a direct bolt-on. There's been a lot mentioned about using this turbo, and i just want to have things cleared up once and for all.

ADAMbc5 has it on his 91 turbo. it will bolt right to the exhaust side just fine. the compressor/intake side is a little different. :D

Actually the compressor side is nearly identical to the turbo that came off my car...oil and water lines also bolt right up. Exhaust side is teh same too..all Subarus use that same flange design for the up-pipe and downpipe sides..the TD05's have a slighltly shalower exhaust housing than the IHI tubros, but that only comes into play if your downpipe has a seperator in it (ala BPM). I ran into no isses at all using the HKS downpipe for a new WRX on my car..just needed to extend the O2 sensor wire roughly 5 inches.

However, this turbo flows considerably more air than the stock unit, so an intercooler would be a mandaotry addition to the turbo. Ding this is pretty straightforward, albeit a bit time consuming....basically a matter of rerouting vaccum lines. I did the swap almost all myself (with some help from one of my shop's employees) over the span of 2 days.

So the TD05 will bolt up without having to modify the upipe flange? How much boost is this turbo rated for? How about turbo lag, is it much? BTW Adam, significant interest has been shown for the 93-96 WRX intercoolers, I think its something like 8 people now.

Up-pipe is eactly the same. It is important to note that this is a TD05 16G turbo for an early WRX, not for an Eclipse, or other Mitsubishi (which use the same basic internals of this turbo, but different housings/flanges).

Lag will vary greatly on the rest of the setup. On my own car (3 inch HKS downppe, high flow cat, 2.5 inch catback), lag is really not much worse than the stock turbo. The difference here is airflow...this thing vastyl outflows the stock turbo, as well as many of the IHI turbos that are upgrades" for Subarus. I keep mine at bar everyday, but you can reliably use it to about 17-18 psi without harm, so long as you ahve the fuel to back it up, and of course, the proper mapping of the ecu.

Again, prices vary depensing upon supply at the time of inquiry. I'll look intot hough and get back with turbo and IC prices for everyone.

The turbos used on all '93 - '96 WRX's will have the 90 degree bend on the compressor side

OK, here are the turbo and IC prices. Have to check my suppliers stock, but he knows for sure he has 5 of each at a minimum. These items are used, but fully inspected and guaranteed to to be in good sound operating condition. I have dealt with this firm personally for awhile now, and have boght everything from trannies and motors, to teh intercooler and turbo i am running curently on my Legacy Turbo...so in other words, I trust him implicitly (sp??) :)

TD05 turbo: $375.00
Intercooler to suit above (comes with piping): $300.00
Prices include shipping from my supplier oversas to us (hence the slightly high prices), but do not include shipping to th end buyers...shipping costs would range from $10.00 to $20.00 for the 48 states via Fedex Groujd depending on your proximity to NY.

what do you mean by that? smaller in size or smaller in depth? the latter i suppose, since you mentioned it flow more. do you happen to have a flow comparison chart of say the vf series turbos vs. mitsu td turbos? :o

Is a TD05 the absolute biggest turbo we can fit in our car? (DIRECT bolt on) Assuming that we have enough extras to back it up. (i.e. IC, fuel etc)

Thanks

I believe so and have been told this by several people. The only reason that I am selling mine is that I didn't replace the stock turbo soon enough and when it blew evidently part of it went through the motor and I need the $ for the rebuild.

I recently took possession of Adam's car. I must say, his descriptions of the car's performance were right on the money!! Spool isn't anything I'd call as frustrating, and it seems to take the the TD05 very well and without any type of piggyback fuel controllers other than an HKS FCD. I'm gonna try out a S-AFC after the holidays and take the car to get tuned/dynoed at TurboXS . . . I'll let you know what I find out (powerwise anyway).

FWIW, Adam gave his best estimate at a mid-13 sec car . . . I believe him, judging by some random run ins with a Mustang GT and a GS400 over the weekend.

Is the Small 16G compressor Turbo any much of an upgrade from the RHB5?

Got this off the nasioc board. I'm not sure just how accurate the approximations made on some turbos are, but the TD05 even with the "small" compressor flows alot more air than the WRX TD04:

Not exactly sure. There's not a lot of information on the web on the RBH5 . . .

Awesome chart! Figuring the TD04 (which flows 360 cfm according to the chart), is only the slightest upgrade from an RHB5 I'd figure 340-350 cfm at 14.7 psi. Don't quote me :D , its just a rough estimate from looking at some of those numbers.
