Default 88' 626 first project in along time

I picked up this gem about 6 months ago. 88' Mazda 626 4WS, turbo, auto. It had been sitting for 2-3 years. the previous owner had the turbo rebuilt because of a bearing failure. Well they put the rebuilt turbo on and it lasted about 50 miles and they thought the engine was toast. I bought the car, took of the turbo and found the oil supply line completely blocked with carbon ----. cleaned it out and in the meantime picked up a fully functional 90 probe GT with a 5sp tranny. the kid who owned it hit a deer with it and said ---- it I guess. I basically got the car for free. so said probe was raped of all its good parts and taken to the scrapyard. I stuck the stock turbo on the 626 and drove it for awhile. BORING! In the meantime i was piling together all the ---- I would ned to do a turbo swap so a few weeks ago my buddy came down to my work with his TIG and helped me make this into a fun car to drive. I did the 5sp swap the day before. Enjoy

Ching chong WG. ******** sent me a 16 psi spring instead of 8psi so I took it apart cut 3/4 of a coil off the spring flattened it out a bit so it would sit level and voila solid 11psi

4WS. four wheel steering. to answer, no. the shift rails between 4WS cars and non-4WS cars are different. my 5sp stuff came from a probe, so no 4WS there...had to bend the rails to get them to fit and had to remove the shaft that goes to the rear steering ---- to clear the rails. and I still have some issues with 5th gear, replaced the synchro but the gear may need replacement too, or may be still just a linkage issue. the 4WS didnt work anyway so I dont give a ----. in the future I may try to remedy the situation, but right now Im thinking MS, JAW, custom equal length runner manifold and 300 whp in my future.

Are the exhaust ports connected in pairs, or do they just go 00 00 ??

the stock manifold has individual runners. there just direct and not equal length...but yeah from the head its like 00 00 instead of 0 0 0 0 like some other engines.

Looks good man. Hows it run with the vaf inline with the TB like that? I've been thinking of running that setup too.

it runs great...seems to start hard unless you crack the throttle though. im not too worried. ive been studying up on MS and will probably get that ---- rolling here in the next month or 2 when I have the specifics worked out.
