Ok I found some more information after talking to my DSM friends and Rotary head Boricuas who have been modifying turbos for different platforms for long time now.

Without knowing what compressor wheel they are doing I can only assume they are using a 25g or something close. In theory I was advised that the choice to machine the stock compressor housing to allow the bigger wheel to fit will result in added power while keeping the lag to the most minimal change possible. As we have seen, the baseline providers of modified stock frame turbos like CBRD and FP all use a slightly larger compressor housing to allow space for the new wheel. If I'm correct, this housing will need more pressure and air volume to spin the wheel, hence turbo lag. By recycling the stock compressor housing with minimal machine work, the result could be a larger flowing turbo with much less lag than anything out there.

Like I said, the car in Jamaica was modified on the stock 8 turbo, much smaller hotside, and it broke 400hp with no change in lag. I'm trying to find more information about this car and will post it as it becomes available.

I was about to send my turbo in, "Guinea Pig", but I stopped to rethink my choice since the proven companies all have chosen to change the compressor housing overall.

Nevertheless, EVERYONE AND I MEAN EVERYONE in Florida know that these guys do some amazing things on rotaries or pistons straight drag beasts. Everyone in Puerto Rico orders from them and if you are not familiar with Salinas, some of the most impressive cars come out of this little island. Some of your comments are right on point but without data is a bit difficult to come to conclusions. I may just do it and if it does not provide the expected gains I can always send it in to CBRD or FP for the compressor housing upgrade. $1k spent in experimentation. I guess someone has to pay it, right?

 

CBRD and the original Red and Greens all used a stock compressor housing from a 9 turbo. That housing is plenty huge for the power the turbo should produce. It is almost as large as a t4s compressor housing. The newer FP housings are not to increase power but to stop compressor surge.

 

Then I stand corrected, I guess the recent reading I did was on the newer FPred hence the use for the newer larger compressor housing. I just read CBRD also do machine work to fit their wheel versus changing the compressor housing overall. Thanks for the clarification.

 

You can order a black with stock 64mm cover. There are a few running around already.

Mike knows his stuff but the turbo he will make for you will fall far short of anything FP makes. There is no substute for years of making turbos for the same engine. Mike very well may be stuffing a 25g wheel in there which is no big feat for any turbo shop. The problem is it wiont spool as fast as FP black yet it wont make the power of the FP green.

 

Sunday morning bump to see if anyone has anymore opinions or info on http://www.miketurboinc.com/ and stock frame turbo conversions.

 

sponger pr, if this is what you want, then go for it! i just noticed that there local to me... i always liked working with locals. i wouldnt mind trying it out. good find!!

 

never a bad thing for people to have other options for stock housing turbos... and if its competition, then it makes everyone else work harder.

looking forward to your results.

^ and thats why CBRD is awesome!

 

Hmmmm, don't know if he knows a lot about Evo's, but this Silvia is a MikeTurbo car and it appears to run strong in the 1/4.

so for $900 the guy from jamaica with the evo8 got his car to make 400whp?? why not buy an evo9 turbo which is a lot cheaper and 400whp is easily achieavable???

 

I think for a budget its a good idea. If you have more money to throw at the situation i might go with FP. CBRD....etc. But for 550$ + - I can't see how you can go wrong.

 

Why not just buy a 20g wheel and put it in yourself? You can get 20g wheels for under 100shipped http://cgi.ebay.com/ebaymotors/Mitsu...item563c103e15 then just port the compressor housing yourself for 7 bucks worth of sandpaper bits. Or buy a new hosuing and 20g wheel for under 200shipped http://cgi.ebay.com/ebaymotors/Turbo...item1c127a5ac7

 

Being different never hurts... also makes things interesting. GL man

 

All "20g" wheels are not created equal, you get what you pay for. Not to mention you still would need to find a place to balance the assembly unless you like blowing up turbo's as a hobby.

 

I know cars are an expensive hobby but blowing up turbos for fun seems a bit excessive. lol
