BE SURE TO CHECK LOCAL LAWS BEFORE CHOOSING TO EMPLOY ANY OF THE FOLLOWING ADVICE, I TAKE NO RESPONSIBILITY FOR ANY DECISIONS YOU MAKE AND AM ONLY HERE TO OFFER INFORMATION WHICH SHOULD MAKE BUILDING EASIER.
After a lot of exploring through this section of the forum I have asked the Moderators to allow for some revamping which may clear up some questions. Prior to this thread there was one which had a list of available turbo kits for the Beta engine, however about 90% of the information no longer pertinent in that many of the companies were out of business or provided questionable customer service.
I am going to lay out as much information as possible to make everyone's lives easier when planning a turbo build and commencing with a project. The previous thread available here in the F/I section was very out of date and reaching anyone who started the thread was impossible so feel free to contact me with any i4 turbo questions and I will be happy to try and answer it. This thread is designed to get you headed down the right path and cover your basic questions, as you get further into your project there will be other minor things you discover of course.
There will always be costs which you may forget about while planning a build and will either delay your project for a few weeks or steal cash from your wallet right away so be prepared for a few of the following.
- Never reuse! The amount of work you will be doing doesnt need to increase because you thought a few dollars could be saved on that pesky gasket.
- This should be a given no to reuse so figure about $50 for it as well
- About $60 per set...if you reuse these they will torque different than if new and not quite work properly. At that point you will need a new set of bolts anyhow and perhaps head gasket at the same time.
- Replacing internals? Yep a brand new set of bearings will be required even if they have no visible damage.
- Ugh! If you are replacing your pistons then send your block to be honed and inspected. I paid $500 for the basic work to be done (cylinder bore, steel blast the block, hot tank both block and head, parallel deck the block, resurface head and micropolish the crankshaft.) TRUST me you dont want to tear your entire engine apart again because you didnt ensure the block or head was true. Might also need your flywheel resurfaced.
- All the ones you drained out have to go back in...so dont try and be cheap with things like transmission fluid or engine oil. Do your install when you need a regular oil change anyhow, and prepare to use synthetic from now on.
- This would be a perfect time to replace those belts that might be wearing out.
Timing belt kit and water pump
- This is the perfect time to take care of this kind of maintenance. Should run you about $100
- Not the cute furry kind but the ones that hold oil in, for instance axle seals. They are about $10 each and might possibly tear if you're not careful...while the axles are out be sure to replace the C-clips on the end of each...they lock your axles into the differential, might want them to be in good shape! Did the crankshaft come out of the engine? New rear main seal and front case seal kits will be needed.
Kspec sells rebuild kits that come with a lot of the things you could need but there is always something else, we are trying to mitigate that by making lists!
Very important things to consider before embarking:
- Will you have access to a 2nd vehicle while your Tiburon is down for extended periods of time? This is inevitable trust me.
- Do you have the proper tools and knowledge to install the kit yourself, diagnose both mechanical and electrical problems, and space to adequately work on your Paperweight?
- Is your current lifestyle going to allow for many hours away from friends and or family while you bust up your knuckles taking care of the above issues?
- Do you have a trusted mechanic to do the install if you are not capable?
If you answered yes to the above prerequisites, then proceed to the next step of planning:
- What amount of power are you looking to make? This will weigh entirely on how much money you will be spending on parts to both achieve and support this goal.
- Will you have any local distributors to bring parts in within a 24-48hr time frame? Not required but immensely helpful.
When planning your build you can pick 2 of the following 3 adjectives to describe the finished product;
Check out the i/4 engine bay thread
for layout ideas while you are contemplating the build.
Do it once, do it right. Plan what you are going to do and piece together your kit.
Fuel delivery system (5th injector or added fuel rail)
External MAP sensor
Blow off valve
Wideband o2 sensor kit
Oil feed hose and restrictor
Oil drain hose (tap oil pan or block)
Coolant feed kit (if required by turbo)
Upgraded clutch (Std Trans)
Upgraded oil cooler (Auto Trans)
Stiffer engine mounts (solid or polyurethane)
Colder heat range spark plugs (I use BKR7)
Exhaust gas temperature gauge
Oil pressure gauge
Manual boost controller
Limited slip differential (LSD)
Low compression pistons
Large bore throttle body
Return fuel system conversion (03+ have returnless system)
