I've been away from the market for a while. What is the best SS exhaust manifold for the 7MGTE? Features I am looking for are thick materials, no clearance issues for oil filter and down pipe, no cracking issues, quality welds. Any thoughts on who makes the best product. It's for a T4 turbo...

While looking on eBay for a new T4 manifold for my 7MGTE, I see that CX Racing / CX Motosports is selling what seems to be a decent looking manifold...

This has been haunting me for as long as I can remember but I thought I'd try to pick everyone's brain one more time. My car continues to backfire when I shift gears. It actually backfires when I get back on the throttle after shifting slowly especially at low RPM's. If I shift quickly and...

After driving on the same afm for over 20 years, all of a sudden I have gone through two afm's in about 3,000 miles. Bad luck or is there something that might be causing this frequent failure. Al wiring looks good and afm body is solidly mounted to the wheel well. Any ideas? Thanks

I have an '89T with the following upgrades: Lexus AFM, 550's, Walbro, AFPR, SAFC 1, Spearco I/C, CT26 54 trim. I drove it to a local club meet the other night and it ran great. 15 lbs solid boost with no issues. I parked it for about 4 hours, had dinner, did the show and shine thing. When I left...

I'm getting ready to install my SP58GT turbo on my 7M. I plan to run about 15 to 18 psi boost max and would like opinions on what sized wastegate I should be using. I already bought a Tial 44mm wastegate but am now wondering if I should be using a 38mm wastegate instead. Some people tell me I...

I need a new front strut tower brace. Most available are for the JZA70. Will these strut tower braces fit properly an an MA70 without issues are are spacers needed? In my case I don't have TEMS so that isn't a concern for me. If spacers are required, how thick do they need to be? Thanks.

I am about to have a block and head machined for a MHG. Does anyone know what the thickness is for the stock head and the height of the stock block? I bought an engine that was not supposed to have been machined but I want to take some measurements to be sure so I buy the correct thickness of...

Anyone have some facts about the efficiency of a metallic core vs cermaic core catayltic converter? I am looking for the cleaning efficiency (for emissions) of the two substrates and not the flow capability. Thanks

Had my MKIII on the dyno this w/e for tuning and found that I am losing boost. Car boosts great to 14.5 psi at about 3200 rpm but slowly loses boost to redline, actually it drops off pretty quickly after hitting 14.5. Boost will drop to about 12 psi by the time I hit redline. No hose leaks...

I have been using Hawk HPS brake pads in my MKIII with good results. I am installing Wilwood calipers this winter and would like to know if anyone could recommend a Wilwood brake pad compound that would be suitable for street only use. I still may go with the Hawk pads but I thought I should...

I want to remove the front wheel axle hubs, to unbolt the brake dust shields so I can trim them properly for my big brake upgrade. The TSRM says I am supposed to remove the whole steering knuckle to disassemble the hub from the knuckle. Question is - if I disconnect the tie rod end, rotate...
