Seriously a v8 would be best and have the least bit of reliability problems. Thats what I hope to do once I get out of college. Plus, v8's just sound so damn good!

Ok frog you seem to have owned cars etc and bought stuff other people told you to buy fine. The thing you are failing to understand is well the whole concept of turbos in general.
Making inquires on wether you can run a 3071 on a td04-h manifold is simply ludicrous. For one the 3071 is a good 30+% larger and not a mitsubishi family design bastardized to fit a niche kit. If you want an off the shelf solution for your power gaols then Flying miata or begi can take care of you quite handily. Given that you have the cash of course.
The most of us here are into making our own inferances and trying things. It is that lack of initiative to educate yourself that bothers us. Saying that a WRX u own with a 2.5 liter and turbo a good 25% bigger than your greddy can make 100 more hp than stock given more fuel etc is a rather well retarded statement.

You are dealing with a car that makes 100-120 whp on the 1.6-1.8 liter motor and trying to triple the horsepower. To equate the power gain what you did with the WRX is equivalent to us getting 150-160 whp. To equate a 350-400 whp miata your wrx would need to be pushed to 900+ whp to simulate the percentage gain you are dealing with.

A GT3071(wg) has a T2 inlet. It will bolt onto the GReddy manifold. You're on your own with the downpipe though.

Thanks for your reply

Regarding my WRX. It is actually a Jap spec '92 car so the original power was only 235bhp. I run it for a few years with 550cc injectors, 18g turbo, 3" full system from turbo back, ported headers, induction kit, fmic, apexi power fc, apexi avcr to name a few of the mods. That was dyno'd at 330bhp/305lbft

The bottom end went and the best option was to fit a 2.5l short block new from subaru. With the same mods, it must be just shy of 400bhp. I could fit a bigger turbo and get more hp as the engine should be good for 465 at the crank.

My mx5 has been turbo'd for a year with the greddy turbo kit. It is still the standard clutch in it and it mostly slips over 5k revs. I have clutch, fly and torsen diff to fit, but I've only done a few thousand miles in it since last summer when it was turbo'd. The winter hasn't been too good here and I have 7 other cars to use so parked this up for the winter.

Now with the better weather setting in I am looking to rebuild the engine as the valve stem oil seals have gone and I have a spare 1.6 engine and already bought the forged pistons etc.

I was hoping to build a 350/400hp setup here hence the original post.

I was looking at the following setup for my 1.6
Belfab Racing bottom end kit (Supertech Pistons + Pro H Beam Rods)
GT3076R
Emerald ECU
FMIC
1000cc injectors
FM 2.5" exhaust system
Walbro 255
Aquamist 2D Water injection + DDS3 Display
Coolant reroute

I was going to use the standard valves. Do you think this would be ok, or would I need the supertech ones too?

thanks

The latest plan you laid out seems very feasable. Valves etc are only going to be an issue for you past probably 400+HP and 8 k or better rpm redlines where you will probably be impeded by flow and a generaly to small lift from your cams etc.
So long as you grab a clutch type lsd for you differential (becouse torsens will cry at 300+ hp) and i would spring for a 6 speed transmission as those are the stoutest avialable to us of the shelf. Otherwise looks like you can definatley do 400 hp with that above listed items. I look forward to some pics once you get it done and start shreding pavement.

Now that this thread actualy has some real meat on it lets try to not rag on him to much guys. this thread has been enough

thanks for you comments

A couple of quick questions, where can I buy the GT3076R turbo? Where can I get a manifold and downpipe to match?

will these injectors fit fine? eBay Motors: RC Fuel Injectors Mazda RX-7 RX7 Denso 1000cc 1000 cc (item 360142981298 end time Apr-27-09 17:07:13 PDT)

they should but you will have to swap the pigtails out.
How the hell are you gonna controll them

I think even a Motec or tec 3, or a haltech would have trouble with those on a 1.6-2.0 liter. Begi has some very nice of the shelf options and will most certianly be able to accomadate you on the phone or by email.
Unfortunatley all the sources i know of are in the US and your shiping and tarrifs will make them alot more expensive. Alot of my freinds overseas like to have there stuf sent to a local American military base where your buddy can get you the stuff for about 1/2 the shipping price.

I dont work for begi or have any affiliation with them. I am just resounding what I have heard and seen from them in the past.

On a side i would look at maybe some 650's at a bsfc of .65 they should get you to 380 hp at there flow rated psi. But if you bump the psi 5-10 while in boost you should be able to make out 418 or so hp. And more general improvements come about as you lower your BSFC for example with the aforementioned psi bump and a bsfc of .6 you have the headway of 453 hp
The RCengineering site RC Fuel Injection and the witch hunter Fuel Injector Calculator from WitchHunter Performance sites will help you to better understand fuel injectors and the choices ahead of you.

deatchwerks will be offering 1000cc injectors in the future according to a thread on here. Adaptronic as well as ms and hydra should be able to control those afaik. A gt3x turbo can be found just about everywhere, so that should be no problem. For a manifold I'd get something similar to the ramhorn that JayL is running on his monster setup.

You have a good point. I really dont think he'll need anything bigger than 800's either, but if he MUST have something that huge that is where he could get it from in the near future.

I've seen plenty of cars make 400-500whp on 750's, so 800's should be more than enough. 1000's should be good to about 600whp or so imo.
