I would like to get opinions about Cam choices for the NON VVTI, 97 motor. I did search but did not clearly see what I was looking for. OK here is the question. I would like to know of the Cam choices available at this time, what the most cost effective Cam upgrade would be for my motor. I...

99 SC400 VVT-i 93,000 Miles Oil: Mobil-1 5W-30 I was stepping on my car pretty hard today for about an hour or so, until I noticed a light haze of white smoke in my rearview mirror Not good. Changed oil 2 months ago, where I know my SRT ECU, headers, exhaust system has me running rich...

Yeah heres the plan. My tranny shifts at 5900- 6100 RPM. When shift it drops back to 4000 rpm. I am going to dial in Progressivly starting at a 50 shot = 33 % at 3900 Rpm and go to 150 shot = 100 % at 5800 RPM with a rev limit at 5900 to cut Nitrious completly. The idea is shifts of only 50...

High flow Walbro is useless without a Adjustable fuel pressure regulator.

OK hope Peter does not mind but.... this is very interesting. Porting is a art. Ed thanks for the info. Lets see another example listed here. OK whats the diffrence because it seems like your chart and person who ported shows less that 10% gain in flow. Check out this other pre 97 1UZFE head...

I have been looking into if theses will fit the SC400 injectors. These screw into the stock injector holes and then you screw the injectors into these. The Nitrous and fuel is then evenly distributed to each port. If this does not fit then I am going to try this new Nozzel that atomizes the...

Only problem was blew up the plastic intake boot elbow one day. Think it was because of a hole in the rubber fuel line from the dry kit. Ran a real fine tuned 150 shot once on the dyno and got 369 RWHP read on dyno. OH forgot one other mod, SS Headers, and No cats, with O2 Simms. Now...

OK on email. I have a 97 SC400. Mods = 100 Shot Dry Zex, Walbro Fuel pump, Aeromotive AFP, Custom dual stepped X Chamber Exhaust, BFI. Unichip ECU, Ported and Matched upper and lower intake Manifold. In process of converting to 150 wet kit Direct port w/ progressive controller.

At the track you have to have a system and know how to drive. On a close to 1000 HP car a pro driver can cut 2.5 sec or better depending how bad the novice is.

Is that on a Supra or SC4 ? How did you tap the fuel rail ? Did you drill that hole ?

I agree. No harm intended from me. I felt the " spoon fed Child comment was out of place and offensive ". As far as my questions of, if the VVTI head would bolt that is a simple yes or no. As I asked of my second question about the stage 1 porting, I was asking what possible HP could be...

Thanks, this is kinda what I thought. Are you in the process of doing your heads ?

Theres always one in every crowd. Guess you are the one.Being that you are above your experience of knowledge, how about allowing others to respond with knowledgeable facts. You gave your short version of answers and are now on a 3rd post that is useless to my questions, and are now stooping to...

Does anyone know any of these answers for a fact ? Key word FACT.

Does anyone know any of these answers for a fact ? 1. Will the 1UZFE VVTI heads bolt on and match ports and work on the NON VVTI 97 pre Motor ? With the NON VVTI cams. 2. Will the VVTI 1UZFE intake Manifold bolt on and fit on the NON VVTI (97 and earlier) motor and heads ? 3. If you do a...

Would'nt the Cams have alot to do with it also ? Is it not true the the 2J has a little more aggressive cam profile for lift and duration, considering all things equal ?

Distributor cover ?

I say 430 too. The bigger the better.

OK I have seen this in a few other threads but am still kinda confused. I have a US 97 SC400. I have SS headers, Unichip, X Exhaust, BFI, and was running a dry Zex kit, but am now converting over to a Wet kit. My question is about the Unichip and deleting the MAF in the intake. I thought...

Yeah, I have a gauge. Interestingly I was told the book spec for WOT fuel pressure was 38-42 psi or 38-44 PSI, I forgot which one. I would have thought you would be running on the higher end. When I was dynoing, we saw fuel pressusers of 41 PSI on my car. I am also going to run a Hobbs Safety...
