The toughest mounts you can get which fit the stock mid-89 and later brackets are the '89 MkIV mounts. They are exactly the same size as the mid-89 to 92 mounts with the same stud threads. There is one locating nub which needs to be ground off. Otherwise they are fine. They are super strong...

When I did my JDM 7MGTE build, I bought a new oil pressure sender, among many other items. It still read 20 PSI low at idle, and lower yet at high speed. The way I knew was by a trick I've been doing for some years: Take a new oil filter, and a center punch. Make a hole in the bottom of...

Apologies for the disagreement: Rod knock will generally not occur under power because radial clearance in the rod bearings is taken up by compression and power stroke compressive force in the connecting rod. Rod knock occurs primarily under light load or no load "teasing" conditions at...

Air to ice water intercoolers have the potential of really cooling the intake charge if properly constructed with enough surface area and circulation of water to prevent the so-called "stagnant film" on the water side from preventing good heat transfer. The "stagnant film" involves a laminar...

Curious if anyone has experienced sticking ND injectors as I have. The car is not used very often. In winter or poor weather, I start it up once every two weeks, and float charge the battery at other times. Quite often a misfire on one cylinder occurs if not started every couple of days...

At cruise, you really should have some means for purging blowby out of the crankcase with vacuum. There seems to be no provisions for this due to the screened breathers on the valve covers not piped to anything else. Granted, Gasoline is lower in sulphur than was the case in years past...

I'm impressed with your air filter box solution: Innovative, functional and a show piece. BernieK

Air pumps used for exhaust manifold air injection flow relatively little. The purpose is/was to oxidize residual HC and CO to CO2 and water (steam) in the exhaust manifold. Eventually many manufacturers found that the pulse vacuum produced in the manifold runners as the exhaust valves closed...

For the 57 trim CT26 and 3" exhaust I have, I too had surge. Bought a Raptor BOV which I recirculated back to the accordian hose (1-1/2" hole bored in the accordian with sheet steel flanges and secured 4-40 screws on a copper pipe tee, 1-1/2" OD). There was one problem with the Raptor: The...

I had found severe cam bearing wear in two engines, and more in heads I had gotten. It occurs because the cams are fed oil from a small passage in the head into the first journals of each one. Each journal is cross drilled. So by the time oil gets to the last journals (particularly on the...

You need to get as much oil into it as came out. Sounds like the pump filled torque convertor leaving the pan empty. BernieK

McDaddy: maybe I just lucked out, but I used 550 RC (ND) injectors about 35 PSI FP (under idle vacuum), and backed the stock screw out about 2/3 of the way. Reg's screw I do not understand. Mine runs so fine I have not even checked Vf yet, Have 57 trim CT26 and 3" single cat...

After 3 weeks, the shop may claim its not their fault. But take a HG and see if the cylinder sealing bead is outboard of the notch. If so, you should be able to use it as is if no other damage is present. If the bead sits on the notch, then you have a problem. Berniek

VERY easy way to tell: Jack up the rear, put the car in gear (enigne off) and see if you turn either of the rear wheels with the parking brake off. If you can, the opposite wheel will turn the other way, and you do not have LSD. If the axles seem locked to each other (if you can't spin either...

When I had a CT26 upgraded to 57 trim, Performance Techniques in California had new turbine housings for $100, about 2 years ago. Cracks are not always obvious unless you open the wastegate flapper. BernieK

Did you use the stock damper (pulley) on the front of the crankshaft, or possibly an aftermarket type? DO NOT USE AND UNDERDRIVE PULLEY WITHOUT A RUBBER TORSIONAL DAMPER AND SEISMIC MASS (the pulley itself with the stock part. Torsional vibrations set up in the crankshaft can and do...

Maximum fuel mileage will be obtained with widest throttle opening and lower RPM, provided that the ECU remains in closed loop mode to keep the mixture stoiciometric. Specifically, when boost begins, the ECU is taken out of closed loop mixture control, and the mixture richens. The more an...

NO! The harmonic balancer is really a DAMPER, which absorbs torsional (twisting) vibrations in the crankshaft airising from each power stroke. The crankshaft "rings" in a twisting motion which can be destructive (loose flywheel bolts, cracked crankshaft, etc). The rubber mounted pulleys on...

Nate: My experience with retorquing ARP studs with an MHG was the same as yours. I have a 2.2 mm Cometic, and used the ARP lube, went up to 85 pound-feet in small increments. Checked about 100 miles later (3-5 heat cycles) starting on the exhaust side, and found nothing looser that at...

Hey, grumpy old man: Yeah, I'm one too, 67 at next b'day but a kid at heart. Saw your posting about retorquing studs with an MHG after 5 heat cycles. I checked mine (2.2 mm Cometic) after about 100 miles on a freshened JDM engine. Started on the exhaust side, and found all up to torque...
