Caesard Posted April 9, 2013 Share Posted April 9, 2013 The search button is your friend. It's been done to death before, by thousands of people. Don't be lazy. I did mine purely by searching out what i needed. Quote Link to comment Share on other sites More sharing options...

Dnk Posted April 9, 2013 Share Posted April 9, 2013 (edited) Decat, 1 bar restrictor ring, boost controller, TRL fcd if you can get one, grade 7 plugs (copper, platinum or iridium, copper are super cheap, iridium will be around £45 for 6 Run at 1.2 bar and you'll have around 400 fwhp I'd be inclined to pop some new engine oil in along with oil and air filter. Infact before you go BPU i'd be giving it a full service unless its been done recently. Check all fluids and replace if req, check rad cap and engine coolant Use o/e Toyota for filters rad cap thermostat etc I'd also do a brake fluid change and fit braided lines while your at it, also give the brakes a once over and make sure all the pistons etc are free and working as they should and check the main lines under the car Edited April 9, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Westy Posted April 9, 2013 Share Posted April 9, 2013 Don't change the BOV though...stick with stock on the VVTi Quote Link to comment Share on other sites More sharing options...
girth45 Posted April 9, 2013 Author Share Posted April 9, 2013 Why do you reccomend leaving stock bov? Quote Link to comment Share on other sites More sharing options...
girth45 Posted April 9, 2013 Author Share Posted April 9, 2013 Is the vvti supra as tuneable, as a non vvti? Quote Link to comment Share on other sites More sharing options...
Westy Posted April 9, 2013 Share Posted April 9, 2013 VVTi has a MAF sensor...remove the stock recirculating BOV for a vent to atmosphere and you will find that the MAF is telling the ECU that there is more air than there actually is...and the engine will overfuel itself. - - - Updated - - - Is the vvti supra as tuneable, as a non vvti? Yes...just a little more tricky. Quote Link to comment Share on other sites More sharing options...
girth45 Posted April 9, 2013 Author Share Posted April 9, 2013 Thanks good advice with explanation.am I correct in thinking the vvti does not produce more power, but is more driveable and efficient Gary. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted April 9, 2013 Share Posted April 9, 2013 VVTi will not give you more power, but the power and torque curve will be improved and response faster. Quote Link to comment Share on other sites More sharing options...

Just to add I'd also check the condition of the intercooler, if it still has the original one fitted it'll probably be looking very 2nd hand by now (bent/crumbling/missing cooling fins), if you plan on staying at BPU levels then I'd replace with a new side mounted IC or decent quality ducted front mounted IC.

Yes it's pretty simple to do, hardest bit is the fcd but it comes with wiring instructions. Quote Link to comment Share on other sites More sharing options...
girth45 Posted April 13, 2013 Author Share Posted April 13, 2013 After fitting would it need to have boost controller set up on dyno, and would it need mapping , would a atmospheric bov work on a vvti engine, I have been told it would affect the air mass metre and cause over fuelling.

Gary You don't have to have a boost controller, it will take it to 1.2 bar boost if you do though. No need for any mapping, standard bov is fine but if you want to fit an aftermarket either HKS or blitz do kits and they work fine with the VVTi.

shifted Posted April 14, 2013 Share Posted April 14, 2013 Well, explains why I'm hitting 1bar then! haha Quote Link to comment Share on other sites More sharing options...
