Piecing together a turbo kit, any input?
Okay so I've been reding a lot about turbos for the last few months on this site, some great build threads (degreddified sunburst was extremely informative) and I've decided I want to piece together a nice little turbo system. I had a coldside sc 96 that ended up making 250+whp and it was fun but the intense dropoff at the top end left me wanting so much more. Right now I'm on a stock 94 engine with 250k miles and its really strong, oil changes every 3k, preventative maintence, etc. I'm on a tight budget and would like to do it as quick as possible (anxious to get boosted) but I'm willing to wait a little longer to get funds together and do it right. I'm trying to find a good mani/dp for cheap but the best I can find is thre begi mani for 400 and dp 305 :( id rather not spend that much but I with they had the cast mani for the 1.8 on ebay like they do the 1.6. Im looking to make 225-250whp for now with the possibility of easily bumping up to around 275-300 with some engine work in the future. I've been looking at these

http://www.ebay.com/itm/GSP-UNIVERSA...12a19e&vxp=mtr
http://www.ebay.com/itm/GODSPEED-GSP...6714b2&vxp=mtr
Any info on reliablility, hp posibilities, spool time, if anyone is running any of these, etc. I know dustinb was running a similar turbo but the link he had doesn't work anymore. Thanks guys!

They "no hit the block?" What is this supposed to mean? I also read about complications with the churbo's dp flange. Does this apply to the godspeed or do they match up with garretts dp flange?

They are garbage that rarely fits right and worse yet crack soon after installation. There is a reason why begi and FM charge 300 bucks per manifold and 200something for downpipes.
Read the stickies man thats why they are there. Theres tons of information at your finger tips.

I would run a chinacharger any day of the week because I'm a cheap ***, but at the same time, with the plethora of good, used OEM turbos available that don't use the old T3 flange, it seems like a waste of time.
SR20 turbos are popular and plentiful. Myself and a few others have used WRX TD04s with great success. When I can buy a 20k mile OEM turbo for <$125, seems like a good way to go.
There are more turbo builds on this site than you can shake a stick at, read other peoples builds and choose your path.

Okay, so I found a local miata guy. He has an 03 nb and a turbo kit for it but he opted not to go turbo so hes selling it. Here's what it includes
Begi S4 mani/ no dp
Godspeed T25 (SR20) turbo
FMIC and piping
HKS bov
oil lines and tap
FM Voodoo box
I'm just assuming that the mani will fit my '94 since they both have a 1.8, but please correct me if im wrong

I haven't looked at it yet, going to check it out friday or saturday but ill definitely make sure its a begi before i shell out the money. I've never seen either in person but im sure it will be obvious whether or not its a quality piece of a thin piece of sheet metal lol. A question I've always wanted to know is, why do I always see mani/dp sold as sets. Do they have to match and why is that?

Expect not to use the voodoo box... I'm guessing u're planning on doing it properly and not using 12411376 piggybacks to make it....run less shitty.
You can call Stephanie from begi and ask for sizes of the tubes, and other marks you can look at to ensure you're getting an S4 manifold and not the ebay ones.

I was actually going to use it and start off with low 5-6 psi and turn up to 8-9 maybe a little later and eventually go to MS, but im blowing a good portion of my money on the kit right now (poor 19 yr old here) lol me and my dad had a BRP coldside kit with ELF piggyback and that was it and it ended up making 250+ at its best but we turned it down for autox and better street driveability. I believe there was also a chip soldered into the stock ecu that changed the redline but idk if it did anything other than that

Make sure you get a receipt from him from BEGI for the s4 manifold. Honestly you should spend the money on a MS now, learn to tune it, then go turbo after you know how to tune. Doing it the other way will cause more long term headaches.
