I'm going to try to keep this updated regularly in case anyone is interested. Will try to be as thorough as possible in describing the build and problems I've encountered. This being my first boost build, maybe I will address some concerns that a potential new person might have.
Started with: Bone stock 1990 NA, 170k miles. Included was Tein Street flex coils, FM frame rail braces, a set of new toyo t1r 195/45, and some 15x8 XXR wheels. Price: $1600
Stuff I acquired immediately thereafter:
-MSPNP2 from Begi
-750cc injectors from Begi
-Wideband setup from begi
I have nothing but great things to say about begi. The parts were fairly expensive (in my opinion) But I immediately received personalized emails containing confirmation of payment, tracking numbers etc. All three packages arrived 1-2 days later with no issues. The high quality on BEGI products was evident, as each thing came with great instructions, flow charts, specifications, invoices etc.
- Garrett M24 locally (150$)
Got this from a friend, found that it had a small amount of shaft play and was unable to free the housing bolts or snap ring to clock it, which made it useless to me. Later sold on ebay for $200 in favor of the CXRacing turbo.
-intercooler kit from cx racing
- turbo manifold from cxracing
-GT2554 rep turbo from cxracing
The CXRacing manifold is in my opinion the best deal on the market right now as far as turbo manifolds go. the welds are great, it's reinforced where it should be, and it's thick (don't remember actual ga.) Don't use the supplied gasket. However, the turbo has left quite a bit to be desired, as well as the customer service. The gasket is atrocious, the "5 bolt exhaust flange" is a unique bolt pattern which no other company manufactures, and CXRacing doesn't sell a downpipe for the 1.6 unless you purchase an entire turbo kit, nor do they sell a flange other than the one supplied. The flange supplied doesn't have a spot for the wg to open, so the airflow would be extremely inefficient. CXracing supplies no documentation with any of their products other than that it passed their quality check. This means that in order to figure out what each thread size is on the turbo and anything else they sell you (no bolts/nuts are usually included) you have to take a trip to the local hardware store, where they probably don't have the metric size you were looking for etc. Huge pain in my opinion. It took 5 calls and 3 days of not getting called back to talk to a tech at cxracing who was able to provide me with the thread sizes and specs on the turbo (oil restrictors etc). I had no complaint about the intercooler kit other than the clamps supplied are pretty junky quality but seemed to work fine. I would NOT buy anything from cxracing ever again except a manifold, and even that might be a gamble.
The first thing done was install the coilovers. Getting the front coilovers off was kind of a pain for me and I ended up cutting them off, knowing they would never be used again. There were some great tutorials explaining the most efficient way to go about getting them off if this is not an ideal approach for you. I initially had the car lowered too much, but ended up raising it up in favor or a more fun driving experience.
Removed the p/s and a/c lines, and associated equipment and did a loop on the ps pump. Stripped interior. Removed the dash, heater core, stereo, etc. Attempted to clean up the wiring some and only include what was necessary.
Installed the mspnp2 & the afr guage, and got the car set up and running. No problems there to mention. Very simple installs.
Ordered a cheap $20 switch plate off ebay and wired up a keyless ignition using 3 relays (can find my schematic if anyone is interested)
Installed a cheap ebay steering wheel. I wouldn't recommend doing this, and if hadn't made the foolish decision, I would have purchased a more expensive wheel in the $200 dollar range in favor of higher quality. The ebay wheel is the worst quality I have ever seen from an ebay product. Cost was $63.
Ordered Kirkey aluminum seats from Summit. 15 wide, 10 fixed layback angle. I find the seats to be pretty comfortable, as long as you install some foam on the butt part. - total $254. Have yet to fabricate up a bracket for the seats.
Installing all the parts from the cxracing stuff went well. Picked up braided hose locally and ordered fittings for the turbo. The only way I could find to do it with the weird thread on the block's oil outlet was to go from m10x1.5>AN4, to ad AN4 double female line, to an AN4 to 1/8npt female, to an 1/8npt to AN4 .050 restrictor. The problem was finding an AN4 to AN4 restrictor.
This is what's happened over the past 6 months. I have only a few hours a week to really work on the car, so it's been going slow and I haven't taken many pictures. I made this thread as an attempt to start logging work done better and maybe someone else will take interest.
Things that need to be done before the car is really up to snuff and will be followed in this build thread are:
Custom 3" exhaust
welding rear diff
more durable clutch
Will of course be posting dyno sheets when completed.
Total cost to date everything included: $4,445
Target HP is 250whp.
