A few months ago the first cat seemed to be going (was overheating and seemed to have been "crushed"). So I had a new downpipe put in without a cat and the second cat replaced with a high-flow cat. Dyno tests showed a definite improvement. But top HP only went from 203 to 242 at the rear wheels. You say you're getting over 300 with a stock engineand both cats. Am I way below where I should be? Or is there something?else that could be accounting for the difference? Mine is an auto, so that would account for some of the difference (10-20 HP?), but I'm sure not 100?(my 203 before mods vs. your over-300). Advertised HP was 320, but I think that was off the driveshaft, not the rear wheels. Can you clarify all this? Thanks.

Turns out the wire is fine (no short, or break) from the ECU to the AFM, but if you pull slightly on the back of the wire right as it connects to the ECU, it breaks the circuit. The female part of the connector is sliding off just enough to break contact with the ECU pin.

The advertised stock HP was very close to what Lance is claiming at the wheels right now. It either isn't stock, or the dyno was a piece of crap. My bone stock '98 TT with 32k did ~212 to the wheels last summer on a Dynojet that are known to be more 'forgiving' than other dynos. I was interested to see the gain you got with just the downpipe and high flow cat. Thanks for the numbers. And for Dean, your numbers should not deteriorate at all if the car is well maintained. -- Greg Altig Frederick, MD -> Riyadh, KSA '92 Mk III Turbo/targa/5spd (the RED) '98 Mk IV TT/targa/6spd (the WHITE) '85 Mk II P-Type 5spd (the BLUE) "MGMS is a disease...."

There are some good illustrations in there, and generally, most of the connectors on our cars are similar. To access the tiny plastic latches in the housings, first you have to pull some sort of protective cover off or out of the main housing. In the case of the ECU connectors, they're some yellow protective covers. Once you have access, then you get in there (usually from the front of the connector) with a dentist's pick, or something similar, and pry the latch up on the wire you want, while pulling on that wire from the rear. I usually do this with plenty of light, and some reading glasses ;-) Hope this helps. I do happen to have the WHR book in PDF format if anyone needs it. Just email me with "WHR" in the subject line, and make sure your email account can receive fairly big attachments; it's about a 5MB file.

There are some good illustrations in there, and generally, most of the connectors on our cars are similar. To access the tiny plastic latches in the housings, first you have to pull some sort of protective cover off or out of the main housing. In the case of the ECU connectors, they're some yellow protective covers. Once you have access, then you get in there (usually from the front of the connector) with a dentist's pick, or something similar, and pry the latch up on the wire you want, while pulling on that wire from the rear. I usually do this with plenty of light, and some reading glasses ;-) Hope this helps. I do happen to have the WHR book in PDF format if anyone needs it. Just email me with "WHR" in the subject line, and make sure your email account can receive fairly big attachments; it's about a 5MB file.

Hi Lance - I'm still relatively new to the Supra world, but I have a '94 with about 128k miles on it. A few months ago the first cat seemed to be going (was overheating and seemed to have been "crushed"). So I had a new downpipe put in without a cat and the second cat replaced with a high-flow cat. Dyno tests showed a definite improvement. But top HP only went from 203 to 242 at the rear wheels. You say you're getting over 300 with a stock engineand both cats. Am I way below where I should be? Or is there something?else that could be accounting for the difference? Mine is an auto, so that would account for some of the difference (10-20 HP?), but I'm sure not 100?(my 203 before mods vs. your over-300). Advertised HP was 320, but I think that was off the driveshaft, not the rear wheels. Can you clarify all this? Thanks.

As John said, remove the yellow protector and go from the front with a small tool (the wiring repair manual shows you how to make this tool) and release the latch on the pin. Once the latch is released, pull the pin out from the back. I didn't use any pliers. These pins are a box shape and the contact petal is inside the box. I don't think crushing them with pliers is a good idea. I probed mine from the wire end with the small tool to push the petal more toward the center of the box. Once you have the pin out, you'll see what I mean. This resolved a two year intermittent problem much like yours except it fixed itself as soon as a little bit of heat got to the ECM. Here's a pic of the tool in action: http://www.clublexus.com/gallery/data//500/medium/ISx50_Shifter_connector_cl ose-up_pin_removal.JPG This pic shows something similar to the Supra's ECM connection and how the pin locks are oriented: http://www.clublexus.com/gallery/data//500/ISx50_Shifter_connector_close-up_ front.JPG The pins in these pics are very similar to the Supra's ECM pins - if you look very closely, you can see the petal inside the box element of the pin. That petal is what actually completes the connection, so it needs to go across the box completely to force contact with the male part of the pin.

You also have to remember that no two Supras do the exact same?power?level?even with the exact same model year, same mileage,?and stock or modded performance levels, even?on the same dyno, hence the quoted whp range.? I think my old 94TT auto with 196k miles on it?still was doing about 275whp on a dynojet with absolutely?no mods whatsoever unless you cound the stock equivalent Denso Iridium spark plugs I put in it right after I bought it with 180k miles on it at 10 years old, and it was considered healthy at the time. ? I know that the VSV for the #2 turbo's engagement gets flaky with age on some Supras which makes a?pretty big?difference in performance. ? Even with dyno differences, I gotta say that your quoted 100+whp worth of drivetrain loss seems VERY odd to me, even with the full stock exhaust and cats still on the car... I'll bet you're not getting the #2 turbo added in the mix due to a bad VSV for the #2 turbo in the sequential system... ? As a reference for Supras,?in 2008 I?bought a?bone stock?93TT auto with 120k miles on it and totally bad (smoking like a chimney) factory?twins, installed a used set of?USDM twins,?put?'em in "True Twin" mode, changed all the fluids?to synthetic, gapped?and installed Denso Iridium spark plugs one step colder than stock (IK22), put a GReddy Boost Cut Controller on it,?installed a GReddy 3-row intercooler kit, Rod Millen 3" down pipe, and Apexi 3.75" cat-back, and saw 368whp without a boost controller on Hennessey's dynojet a few weeks later. My 98TT 6-Speed with the same mods other than a lightweight flywheel and?a TRD 3" cat-back instead of the Apexi cat-back put 401hp to the wheels with the boost controller off on that same dyno at Hennessey's place 2 years in a row. That 98TT 6-Speed also?did 365whp on a dyno dynamics dyno?with the same mods and?the boost controller off. That's how drastically different they can be but still...? 100hp (or more)?loss through the tranny and diff seems a bit excessive to me. ? My bone stock 2001 IS300's factory 2JZ-GE?that's rated at like 206 crankshaft hp put 174hp to the wheels on both pulls in 4th gear?through the factory E-shift 5-Speed automatic tranny on Hennessey's dynojet last month with 99,856 miles on the car on 93 Octane pump gas with the original factory denso iridium spark plugs still in it (Lexus recommended 120k mile?replacement interval), all 4 factory cats and the full?factory exhaust?still on it, the factory intake and stock air filter, and a bad S2B2 Oxygen sensor...?

You can disconnect the vacuum lines and test the VSV if you know how to work with automotive wiring and vacuum?or you can carefully follow the directions and do the "temporary True-Twin mod" with the two check-valves as explained on mkiv.com and I'll bet you feel a HUGE difference and see a lot more whp on a dyno like that than you're getting now. Side note:? It's fairly rare but not unheard of to have a #2 that hasn't been run for a while with around 100k miles on a Supra begin to start smoking mildly or moderately once the VSV problem is fixed and/or you run it in True-Twin mode.? Over the past few years I've had?several friends buy TT's with like 70-120k miles on 'em that one of the VSV's for controlling the #2 turbo was bad and as soon as we replaced it to fix the sequential system and they boosted hard?a few times the car started smoking mildly at first then pretty much continuously after just a few more weeks of driving?and the #2 turbo failed soon afterwards. ? With everything else stock but with an aftermarket downpipe and hi-flow cat, I'd really expect to see at least low 300's to the wheels out of a TT Supra on just about any dyno, even through an automatic, unless maybe without a BCC the ecu limits the boost too much for that but even still I'd expect more than 300hp to the wheels regardless since the major?exhaust restrictions of the factory downpipe and stock cats have been removed.

Mine is an auto, so that would account for some of the difference (10-20 HP?), but I'm sure not 100?(my 203 before mods vs. your over-300).

There is unquestionably something wrong with your engine. The first thing I would do is a leakdown test to determine the engine's basic health. If the leakdown show 7% or less, then the problem is external and possibly a VSV or stuck valve in the exhaust or intake which is denying the engine full boost. Do you have a boost gauge? What does it read? Even at the stock 8.8 psig, you should be around 270 whp worst case on a Dynojet dyno. If you're anywhere near Atlanta, bring your car by and we can figure it out pretty quickly. There isn't much I can't troubleshoot on the OEM setup in about 30 minutes or less.

You don't need high octane fuel at altitude because the temperature of the air/fuel mix doesn't get as high when you compress it because there are fewer moles of air in the same volume. Technically, you can run very low octane fuel in gasoline engines at part throttle for this same reason. You're just screwed if you go WOT and need the detonation resistance.

Tony, I just realized I didn't address your question...sorry about that... There is unquestionably something wrong with your engine. ?The first thing I would do is a leakdown test to determine the engine's basic health. ?If the leakdown show 7% or less, then the problem is external and possibly a VSV or stuck valve in the exhaust or intake which is denying the engine full boost. Do you have a boost gauge? ?What does it read? ?Even at the stock 8.8 psig, you should be around 270 whp worst case on a Dynojet dyno. If you're anywhere near Atlanta, bring your car by and we can figure it out pretty quickly. ?There isn't much I can't troubleshoot on the OEM setup in about 30 minutes or less.

Hi Lance - I'm still relatively new to the Supra world, but I have a '94 with about 128k miles on it. A few months ago the first cat seemed to be going (was overheating and seemed to have been "crushed"). So I had a new downpipe put in without a cat and the second cat replaced with a high-flow cat. Dyno tests showed a definite improvement. But top HP only went from 203 to 242 at the rear wheels. You say you're getting over 300 with a stock engineand both cats. Am I way below where I should be? Or is there something?else that could be accounting for the difference? Mine is an auto, so that would account for some of the difference (10-20 HP?), but I'm sure not 100?(my 203 before mods vs. your over-300).
