[B]The speed-craft kit is a major rip off. I recently built my own turbo kit and it added up to around $2600, or around there.(w/o installation and electronic accessories) The kit i built includes:
t04b 60-1 ball bearing turbo ($480)
tial 35mm (not 45mm) wastegate ($260)
Rev Hard custom built manifold ($500)
Rev Hard custom built intercooler ($600)
Apex'i twin chamber blow off valve ($200)
Vortech fuel management unit ($175)
walbro fuel pump ($160)
and the Greddy oil filter relocation kit. ($160)
pricese may vary.

you can get all these things piped in at your local muffler shop, or car shop for about 300-500 dollars depending on their prices per bend.

 

krzys2k,

Just wondering, how is your car running? No problems?

 

Have to agree with UL. I have bought quite a few turbo's in my life and I can't see where you got a "new t04b 60-1 ball bearing turbo for $480". Hell, I've seen used ones go for a lot more then that. If your price is true let us know your reseller.

 

I had just one question for both kits, why is speedcraft and this custom kit using such a big turbo for running 6-8psi? Why not go with like a t3t4 or a 16g turbo for more efficiency?

 

Speedcraft (as a company, I don't care whom specifically did it) has spent alot of time to develop the turbo kit. The 60-1 turbo is super efficient, and quick spooling. It is the smallest version of the 60-1 trim. It is completely spooled by 4000 rpm, and it still able to push lots of boost for those looking to expand.

Anyways, regarding the original post, add up R&D time, fabrication time and subtract the value of your down time, your R&D and potential problems you may have and figure out if it's worth it to you. If you can do it, and the time that it takes you to do it is worth less than the mark up on the Speedcraft kit then go ahead and do it. But don't knock someone else's work.

My original goal was to make my own turbo kit (way back when) but the shop had alot of customers, and couldn't focus on just my project. It would have taken forever to get it running. I shipped my car to Speedcraft and got it back a week later, turbocharged and tuned, it was definetly worth it to me.

Oh yeah, I forgot to mention that there is so little room down in the exhaust side of the engine, you will have to spend alot of time making everything fit... <sarcasm>hmmm.. maybe that's why they chose that turbo? I guess we'd have to do some research...</sarcasm>

 

These are efficiency flow curves , one is of a 60-1 trim and the other is a 50 trim which is more efficient at lower flow rates. However, the 50 trim obviously does not flow as much air as the 60-1, does the F20C really need 60lb/min capability out the turbo or wouldn't it be more efficient to use a smaller compressor which is more efficient at lower flow rates.

i haven't put it all in yet, i ordered everything, i'll let you guys know when i dyno all the stuff in. But all the piping including downpipe will be custom made and bent.

 

Got the turbo from a friend who works for garret/hi-flow or whatever...

 

sorry for the choppy posts..but anyway, you can find lotsa great turbos on ebay, mine was brand new.
Also, my wastegate was brand new too, and ebay as well
