I am building a 4g63 88 RX7as well. The motor gets a bad rap because of the 7 bolt version that has thrust bearing issues, usally due to a heavy duty clutch being installed. The 6 bolts are pretty bullet proof. The 150k motor in my Talon has 100's of passes and run's 12.30's on the stock tiny turbo

Im running a B2600 bellhousing. I originally was going to put a wideblock 4g63 in it but since they are hard to find and I had three or four narrowblocks lying around I decided to go with the narrowblock and an adapterplate. I also didn't like the way the wideblock sat at an angle when bolted to the bellhousing so I stood it straight up with the adapter plate.

So you're saying that even with B2600 bell housing the motor is gonna have to sit at an angle for the for the transmission/ shifter to be perfectly upright...Dammit, I was going to source a wide block 4g64 to used with a 2g head, so I can leave my other drivetrain parts as stock as possible.

Hey Bean, I assume you used metric flat head socket bolt to mount your adapter to the block so to not interfere with the bellhousing. Did you convert your block to course thread or where the hell did you find the fine thread bolts?

Ok, I'll try that. I used some grade 8.8 hardware store bolt and they do have a bigger head. I was going to look at some cap head bolts and see if they would clear better without grinding.

Got the compressor cover powder coated and added Vibrants version on the wiggins clamp.

I was suprised that it actually fit and was nice. http://i290.photobucket.com/albums/l...-56-18_972.jpg I need to run the lines for the AC next week. Driving in the heat without it sucks. |
I had some bumpsteer so I decided to raise the rack up instead of dropping the tie rods more then they already are. With some minor modifications to the oil filter housing I was able to raise the rack up over 1". I cut the subrame and modified it again on the car. I was also able to raise the sway bar 1" also which helped a lot with ground clearance. I need to get the car re aligned next week, make a trans/rear end brace, and then its time to dial in the traction control.

Wet sanded and buffed the car to get it ready for the Exedy booth this weekend at Formula D. Going to be another two weeks before my rims get here so for now I'm on the ones the car came with.

Got the air conditioning working on Friday. I also weighed the car at Englishtown this weekend. It weighed 2890lbs with me in it and a full tank of gas. Im guessing that with the Enkie RPF-1's on it and less then a 1/4 tank of gas I should be under 2800lbs with me in it which will be nice. I will weigh it again next month after the wheels are on it.

Car is looking good man! Gotta post up some vids now :nod:
|
Finally got my rims. They are 17x10 in the rear and 17x9 in the front. I also changed my boost controller lines to -4an since the push lock ones I was using melted even though they were covered in the DEI fire sleeves.

I want to see this thing in person. RPF-1's look perfect on this!

This thread is full of win.

You cut the front sub frame to allow the engine to sit lower. I see in the back you welded a bar bracing left to right. In the front I couldn't see anything inbetween the left n right, unless the rack hides it. Just curious.

I love this build thread. Keep up the good work!

awesome build!

Hey, what kind of clutch master/slave setup did you use?

Better than a V8! But you took an engine out that some uneducated folk think is unreliable and put an engine in that most know is unreliable... Why 4g63 out of curiosity?
Question and excuse my ignorance, have you ever seen a 4g63? They come from the factory with 400hp and stock pistons ,rods,crank can take easily 600. The 4g63 will withstand abuse more than most motors in the world wide market |
