reading the whole thread FTW.

i'm STILL crying on the inside. my friend has his stock WRX turbo in his trunk which i may purchase off him sometime soon. THEN we'll see about those 14s... but that still won't be fast enough!

 

I read the whole thread, I just felt like posting, lol. I wouldn't bother with the stock WRX turbo, if it's the one I'm thinking of it's a TD04 and very small. Go big or go home if you want to get to the 14s.

 

it would help big time cost-wise though. i could get it for less than two bills from him.

it would just be nice to have most of the large parts of a turbo setup... the RRM header doubles as a turbo manifold, i already have the engine management (v.1 piggy), and the 2.5" exhaust should be enough for FI. fuel injectors, a good tune, oil lines, some fittings, and then the IC w/piping and i might be in decent shape.

i just need to nail down permanent employment. bouncing from contract to contract blows.

you like your stock turbo on your WRX though, don't you? i think the lancer might be a little lighter than the WRX and it's only going to be sending power to two wheels. i think i might be able to squeeze stock WRX HP out of the lancer with the right parts and a good tune.

 

The turbo works great on a WRX but it is tiny, put it side by side with a 16g and it looks anemic. It also has an internal wastegate which will make putting it on a lancer difficult. I would honestly spend the money on a T-28 or 16g if I were you. The WRX motor and the lancer motor are completely different so I would really suggest going with a better turbo. You could easily make as much power as an earlier WRX, the new ones (06+) are underrated from the factory and dyno more like a 250 hp car.

 

I should seriously ban you for making a post like this.

TD04 should be fine in the Lancer. Unless he has a built motor (which he doesn't according to his registry), it's not like he wants to be pushing a ton of air anyways...
Besides - everyone yaps about the Lancer doing 7-10 psi before the pistons melt, but that number is just associated with one turbo type. 7 psi on one turbo doesn't equal 7 psi on another turbo when it comes down to total airflow...

 

Lol, ok, not sure where that came from. I still wouldn't bother with the TD04, if not for it's size but the internal wastegate. It's set for 11 PSI from the factory and unless you have a built motor I don't think that'd be a good idea.
Here's a pic to put it into perspective. This compares the 18g from the evo with the VF39 from the STi. The TD04 is even smaller than the VF39.

You could still do it though, only thing you'd have to do is switch from an internal wastegate to an external so you have more control over the boost pressure.

 

Did you even read my post?

11 psi coming out a TD04 is going to be different than the 11 psi coming out of a T-25 or T-28 (which is what RRM uses).

It's not about PSI. It's about the amount of air the turbo is pushing. 11 psi coming out of a garden hose is less water than 11 psi coming out of a sewer pipe, right?

We all agree that 7 psi is the maximum safe number on a Lancer. But what no one ever really discusses is that fact that 7 psi is just on that kit. Almost everyone has the RRM kit, so we just talk about it like it's the only one. But if he has a different turbo, he can see different numbers.

I'm not saying you can run 20 psi off a TD04. I don't know, I haven't done the math, I don't plan on doing the math. But someone should really calculate the volume of air that an RRM T-28 turbo is pushing out at 7 psi. Then they should use that to figure out how many psi a TD04 needs to push to get the same volume.

Is any of this making sense? It all works in my head, but maybe I'm just not explaining it well enough...

 

Yeah I know that, I'm just not sure what the limit is with a TD04 but I would think 11 PSI would be pushing it. The only way to really figure it out is to compare the flow patterns between the two turbos (say TD04 and a T-28).

 

That's exactly what I've been trying to say!!!!!!!!

 

Don't worry Doug I understand your point. I just don't think a TD04 is the right turbo for the lancer, especially if it's coming from a WRX. I doubt the flow ratio is 63% (TD04 vs T-28) which would be needed for 11 PSI on a TD04 to be equivalent to 7 PSI on a T-28. If you could switch it to an external wastegate though you'd solve the problem and have a pretty quick spool time.

 

i thought the evo had a 16g, not a 18g?

see, i didn't know the wastegate was set to 11 on that turbo--that is good to know. i can imagine it would still be cheaper to pick up a compatible wastegate rather than to try to find a compatible turbo.

awhile back i talked about a custom set up with rob, if i ever start getting the parts together seriously i know i'll be able to give RRM a call and get some good advice, aside from the turbo i'd probably be getting all my parts through RRM either way. they may even know how the turbo in their kit stacks up against a WRX one (or can at least tell me all about their turbo).

i REALLY want to get my lancer boosted but the whole money thing is a big pain. i'm around 113k miles as well... if i'm going to do this i ought to do it soon! even then paying off my lancer, getting and installing a turbo AND then having to do serious engine work (which i hope i will never have to do!) will still be cheaper than even a used evo and i can still have a boosted mitsubishi. not as fast, sure... but it will still be a blast to drive.

then again there's always the upcoming ralliart.

 

I think the older evos used a 16g. I'm willing to bet RRM will tell you to go with their kit for good reason, it's already built and everything is good to go (that and their a vendor, you might as well ask McDonalds who makes the best burgers). I have no idea how RRM would be able to build you a kit using the TD04, all the piping would be different, it wouldn't bolt right up, etc.. It'd be interesting to see though, I don't think anyone has done it before.

 

without a doubt i WANT to go with RRM... but i wouldn't be able to afford it right away. i COULD always start non-IC and then source piping and the actual IC--that would still be a bit cheaper.

i suppose i could always ask my friend for all his stock pipes and i could have the flanges cut off of 'em and welded to new pipes for my kit. he DOES have his stock up and down pipes since i helped him out with both... that might be worth looking into as well.

 

I think overall it's cheaper to start with their IC kit right off the bat. Alternatively you could just buy a used kit.

 

also true--too bad yours isn't still for sale. :P

i'm sure once i have enough money to just throw cash at the "problem" i will find a solution. my friend opened two credit cards to fund his 18G, haha. i don't think i will go quite the same route though.
