Wow! I thought we had progressed past this?
I thought the eggplant had been retired and MT was attempting to change the hazing image, guess I was wrong.
OP, it goes like this...
what are your HP goals? ~200
Do you ever plan to track the car?
Do you have the necessary tools to fabricate items like a manifold and downpipe?
Do you then have the said skills to fabricate?
Where are you willing to sacrifice? Time waiting for deals? Blood and sweat doing things yourself? Performance - using a JY volvo T3 vs New Garrett 2560?
You and only you can answer these questions - the build guides here are great for learning what works and is track capable and for getting perspective on how others are accomplishing THEIR goals
Cheap street capable can be done for ~$1100-1400 but you are going to have to build it and I mean allofit.
Manifold - 175
Downpipe - 65
Rx-7 injectors - 80
eBay intercooler - 65
Piping - 80
Couplers - 40
Oil lines and fittings - 165
Megasquirt 1 V2.2 - 165
Homemade wiring harness - 20
Wideband O2 - 150
Ebay t3 - 125
JY Bosch BOV - 5
Now this will allow you to tune, albeit roughly, and not blow stuff up but you are limited. You can beat some of these prices or blow every one of them out of the water depending on how well you can shop or if you know where to look.
Your injectors aren't flow matched so you will have to run rich to avoid detonation and they won't idle well...just not a good injector, they're archaic.
Your T3 will boost slowly and once it does your clutch will quickly start to slip.
This all assumes you have tools, skills and time on your side - only you know if you have ALL 3 of these at your disposal.
For myself, I am planning the follow as of right now, but I have tools time and skill to make everything work as I would like it, but if something needs to change I plan to address that.
Manifold - DIY
downpipe - DIY
Turbo - T25
Intercooler - currently used Begi but may change
Injectors - RX-8 yellows
Oil and water lines - nothing fancy
Megasquirt V2.2 with MS2 daughter board - works great and is a cheap option
Harness - homemade
Wideband O2 - LC-1 with gauge
BOV - junkyard Bosch $5
Clutch - FM II
With any luck I'll have a build thread started here in the next couple of months but like I said, I have the luxury of time
