Locked n the garage again... now look what happened

[RayPeters]

Hey everyone, its been a long time since I have been active on the boards, not to worry though I've got some new bits I'm trying and it looks good so far.
Here's the rub, I've run an 18G for a long time and I like it, but the Garrett t04E wheels are quick and efficient. But they don't bolt to a mitsu anything. I expect this has been tried before, but here's photos of building a 54 trim td05H. I've built a new engine, parked the supercharger for now, and gone to a water to air charge cooler. ( look for it in another thread) So first everyone has seen a MHi 05 series CHRA (photo 1). Setting in the middle of the modified housing is a 14B wheel for size comparison. Photo 2 is of the 2 wheels sitting next to each other. Photo 3 is the modified compressor housing, and photo 4 is the assembled unit. The big wheel in the photo 2 is damaged, I won't be actually using that. I've run it for 600 miles and while the engine is still new I'm stretching its legs @ 12psi now and it feels nice. 3K spool, and should flow ~46 lbs/min. The small housiing will hurt the very top end a little, but some decent spool always has a price.
Speaking of price, I laughed my way through the thred on the ebay/china 16G stuff, here's the actual costs so far for this conversion. $60 for the 54 trim wheel. $0 for the old TD05H, everyone had one of these once. $ 65 for the rebuild kit, $50 for the balance job. $??? for the hand fit of the 54 trim wheel in the compressor hosing. I spent 2 evenings at the machine shop hand fitting that wheel in the housing, so if my time is worth anything, ~$200 should cover it. Totaling that all up, $425.00 out the door puts this in reach of many people looking for max bang for your turbo dollar.

Comments welcome

Nice mutt

Any idea when your going to get in some track time or dyno runs?

 

[RayPeters]

Probably looking at 3 or 4 weeks, I am waiting for injectors and the engine needs more time on it before I start looking at high boost pulls. I will take it to the dyno before the track, not much into drag. Although the Prescott Forest rally is Oct 10,11.... Zero car should be a fun time. I should expect low 400's to be possible given the high number of supporting mods. We shall see.

 

[aero_sallee]

May I ask what influenced you to choose the 54trim over some of the other TO4E wheels? J/W since it doesn't seem to be a common choice.


Could make an interesting sleeper.

 

[RayPeters]

There were a couple of factors that lead me to that wheel, the big one was that is all the wheel that will physically fit in a small MHI housing. A 57 trim would stick through the housing . I looked at all the maps and this seemed to follow the engine's VE well, provide enough PR for my goals and flow should be well matched. I'm going to add a backpressure gauge this weekend and get some numbers there and decide if I need a different exhaust housing or maybe a TD06H wheel.
Stealth is what this is all about. I can show anyone the engine compartment before a race (tech inspectors included) and no one wiill ever know what's behind door number 1. I also wanted the convience of bolt up. I can give this to a friend and he can bolt it to a mildly modded 4G63 and have quite a monster.

Looks like a great toy Ray. Glad to see you're still coming up with unique new stuff. Are you running this on a stroker?

 

[RayPeters]

I decided against a stroker, just don't like the rod ratio. I'm searching for a 4G64 block. I'll go for the full 2.4, bring the supercharger back, and I'm thinking t67 or something big . So the engine is a 2.0, no squirters, STD size coated pistons, evo III cams, 7.8 to 1 CR. Port matching and minor cleanup, 750cc injectors on a 1G mani. 2.5" IC piping and a custom Bell intercooler Water to air IC with intigrated BOV.

 

[stockfornow]

You're crazy!!! In a good way though... So, you're looking for a bigger displacement, and a bigger turbo down the road. I really wonder what it would be like.

 

[eclipsh]

Is that why you went water to air on the IC? Testing it out for your dual charger setup?

 

[RayPeters]

I went wet for a few reasons. First was packaging. I'm tired of 20 feet of intercooler piping running all over the place. Second, I want the option of going with ICE. Third, This is a good test for the inclusion of these in the next twincharged setup. Fourth, and this is the biggie, I can run the AC without worrying about overheating. Here's a photo of the heat exchanger install. The total system volume is 2.6 gallons. 1.2 of that is in the charge cooler, the rest in the lines and the heat exchanger. Intake temps stay 15 degrees or less above outside temp. I have enough thermal mass (the water) for almost 2 min of boost before the water is too hot (170).

I would love to see how this turbo peforms as I'm in the market for a new one. Upgrading my 16g to this would be nice.

I'll post info once I have it. This isn't a commercially available unit though. To my knowlege even Forced Performance isn't using a 54 trim in a 05 mitsu housing. Maybe someone can shed some light on this? They build something close but like all their turbos, they won't tell people what's in them. Hard for me to consider such a purchase when I can't plot my demand lines on a compressor flow map.
I've made 2 of these, a primary and a backup, like all DSM parts a spare in the garage is cheap insurance that nothing bad will happen.

Spool is very 16G like, the surge line is a little flatter although more linear than any of the G wheels. I'll know more next week when I turn the wick up and get serious about making some power. Going to retorque the head again this weekend and do a compression check to make sure everything is looking good in there, then start looking for the flow limit on the system.

What do you mean you have 2 mins of boost before the water is too hot? How fast does it cool down? What size heat exchanger are you using? where did you locate it?

I didn't think that statement needed alot more support. The heat exchanger is 23 x6.5x 4 inches and is fan cooled at the hot end. Water circulation rate is temp controlled and looks to take it less than 5 min with the fan to bring the system back to ambient plus 10 from 170. The heat exchanger is 2.5 times larger than the charge cooler.

 

[Boosted98gsx]

Can you say turbine choke?

 

[KPEclipse]

Wow - this thing looks to be quite promising...good luck with it ray. As stated above, cant wait to see what type of numbers you put down with this, especially because I'm already looking to get off of my 14b and get a good time, and I got a brand new b16g for a killer price - it'd be great to upgrade to this, and like you said, pop the hood and have it's appearance fool every and anyone

 

[RayPeters]

Can you say turbine choke?

What are you refering to?? I have yet to measure backpressure from the turbine, but the calculations looked favorable for my goals. Maybe I will end up with it in an 8cm housing.

So do you like the performance of the water intercooler over the air / air? I remember we had those convo before in the supercharger thread, but i'm just curious.

 

[RayPeters]

yeah so far the system is working well. It isn't as cheap as some FMIC's, but the up side is my UICP is only 20 inches long. Plus packaging is easier. I had to buy two heat exchangers. I could run a much larger charge cooler if i thought I needed to, there is room for probably 15 x 6 x 4.5 wich would be 50% more cooling area than I have now. The issue then would be the heat exchanger. I could double the height of what is there now, and I will need to when I go back to the twincharger setup, but for now I am happy and it fits well in the car. if I ever get really serious, I'll pump ice water through its veins.

frozen boost.com sells a well matched kit, I just don't like their heat exchanger as it covers the whole radiator opening.

 

[DSMunknown]

Terrific. Looks like something I would do if I had enough time/money/energy/skills/knowledge. I'm all about "sleeper" style. <a href="http://planetsmilies.net" title="happy smiley"><img src="http://planetsmilies.net/happy-smiley-8836.gif" alt="http://planetsmilies.net/happy-smiley-8836.gif" title="happy smiley" style="border-width:0;"/></a>

I recently had the same done with a Small 16G and Garrett compressor wheel that I had lying around. It's a 7-fin wheel, and is ALOT bigger than a 20G compressor; I'm not sure what it came from but the Small 16G compressor was mangled and I had some time on my hands:

The turbo is going on a 1997 GST that belongs to a friend on mine....I'm curious to see how it works out!

The best part.....TOTAL SLEEPER!

 

[JusMX141]

Should've included this in the last post.....

Here's the Hybrid 16G next to a standard Small 16G:

Nice work, guys. This may be a hot ticket for anyone competing in the Stock Appearing class at the Shootout.

 

[JusMX141]

Right...and if you wanted to go total sleeper, you wouldn't strip and polish the cover like I did; just keep the Small 16G part number visible and it's all good!

 

[RayPeters]

Another nice Mutt, are you sure that isn't a 7 fin Holset compressor wheel, I didn't remember the Garrett line having 7 blade wheels. Somone with a lot of garrett experience chime in here, I'm a mitsu man...
