SupraSymz Posted September 12, 2005 Share Posted September 12, 2005 Last couple of weeks I've been ripping out my aerotops NA engine and rebuilding a Brit spec TT engine & manual box I picked up in a scrap yard. Hope to have it all cracked by the weekend. Q1. I've sourced everything else that needs to go in with the engine, all except a flipping MAF. Do I need to bite the bullet and see Mr Toyota for a stock MAF, or does anyone know of an aftermarket replacement (or indeed any mod that requires you to remove the MAF as part of the upgrade?) Q2. Unrelated question really, but after all these endevours, what sort of BHP should I get from the car? (spec - UK spec rebuilt engine, K&N cone filter on HKS induction pipework, turbos just been refurbed by turbo dynamics, HKS FMIC, HKS SSQV dump valve, HKS iridium plugs, both cats bypassed, full Blitz NUR spec exhaust.)

JohnA Posted September 13, 2005 Share Posted September 13, 2005 I would have thought that the simplest and cheapest solution would be to find a MAF from someone who's ditched it (don't assume that the TT VVTi MAF is the same, it might not work properly) There is a product called HKS VPC which is meant to replace them MAF, fooling the ECU into thinking that it is still in place. Works OK judging from the feedback in SupraForums, although it is open to debate whether it brings any of the 'improvements' claimed by the manufacturers. I would expect it to have an edge if you run the engine at higher boost pressures, having zero restriction in the airflow. It also acts as a fuel cut defender I think, so you'll kill two birds with one stone. Worth a try perhaps... Link to comment Share on other sites More sharing options...
arnout Posted September 13, 2005 Share Posted September 13, 2005 I have four MAF sensors here, if you need one let me know. trades welcome, otherwise paypal. Link to comment Share on other sites More sharing options...
JustGav Posted September 13, 2005 Share Posted September 13, 2005 The HKS VPC is an old unit and as far as I know is not available any more.. Something like a MAP ECU is also an alternative... I'm in the process of using an emanage ultimate as a MAF replacement, but not actually fully tested yet Link to comment Share on other sites More sharing options...
bromy Posted September 13, 2005 Share Posted September 13, 2005 Have a look on supraforums there are a fair few people that use the lexus V8 MAF Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 13, 2005 Share Posted September 13, 2005 Get the genuine Toyota MAF, from a UK car, the VVTi one is quite different. Unless you are going to run some aftermarket ECU, then you could probably run a MAP sensor system, or map to suit any reasonably sized MAF unit from another application. Stock is by FAR the simplest route. Good luck, I like these more adventurous projects people are taking on nowadays. Link to comment Share on other sites More sharing options...
JohnK Posted September 13, 2005 Share Posted September 13, 2005 As for power, 326 for a stock engine minus loads with an induction filter. Link to comment Share on other sites More sharing options...

SupraSymz Posted September 13, 2005 Author Share Posted September 13, 2005 1. Man, less than 24 hrs later and you fellas are saving my ass. Cheers guys, this is a flippin great web site/forum/club/whatever. 2. I'll definitely take up the offer of buying a MAF from arnout if you've got a UK spec one. 3. Slightly gutted that JohnK said I'd lose power (huh?) using an induction kit, I've seen web sites saying you gain upto 15 BHP using an induction kit generically, but is it the common Supra understanding to use the manufacturers air box because it is more efficient??? (I still have it and after all this effort just want to get the best out of what I've got). 4. Also JohnK, will I not expect to see any power gains from the big FMIC, sexy plugs, cat bypassing and bigger exhaust? (Can you hear the pleaing in my voice here? can you hear it?? can you???....)

Simon the induction kit will suck hot air from the engine bay hence lose you power. you may want to put the airbox back in or make up some cold air feed/ducting. the decat on a uk spec doesnt really raise boost. you will need a boost controller to get some decent power. get your self a fuel cut defender from thor and then fit the boost controller. you should then see 400+ bhp Link to comment Share on other sites More sharing options...
JohnA Posted September 13, 2005 Share Posted September 13, 2005 Cheers guys, this is a flippin great web site/forum/club/whatever. it's a way of life 3. Slightly gutted that JohnK said I'd lose power (huh?) using an induction kit, I've seen web sites saying you gain upto 15 BHP using an induction kit generically, but is it the common Supra understanding to use the manufacturers air box because it is more efficient??? of course it's more efficient, do you think Toyota engineers were not competent enough to make a half-decent airfilter? People can claim power gains even when they change underwear. If you don't do before/after measurements yourself you'll never know. Stock is best mate, and continues to be until you exceed stock power levels by a large margin. will I not expect to see any power gains from the big FMIC, sexy plugs, cat bypassing and bigger exhaust? (Can you hear the pleaing in my voice here? can you hear it?? can you???....)Simon The above will allow you to run 'safely' a bit more boost, so that's where the extra power will come from. Not all of them are 'must haves' but they won't hurt either, if done properly. Link to comment Share on other sites More sharing options...
JohnK Posted September 13, 2005 Share Posted September 13, 2005 Im sorry if I have offened in my comment about the induction filter. The more I look at them the more I despise them. As has been said, they suck in hot air, another point to not is they dont often have the surface area of the stock filter. You might also be supprised to hear that some of the "big name" filters are actually crap at filtration. Now before you look at my website and call me a hypocrite, As soon as I figure a way to fit the stock box back on without putting too many bends in the piping the induction filter will be in the bin. (or on ebay for a chav to buy) Link to comment Share on other sites More sharing options...

But seriously, do you guys think that you could add the induction stuff to your sig section, so that it doesn't have to be brought up in every thread like this?

JohnK Posted September 13, 2005 Share Posted September 13, 2005 What do you mean add it to my sig section? It does need to be brought up, even if you want it for looks and dont care about the performance issues, poor filtration has got to concern you. Over time its like shot blasting your turbo blades.

JohnA Posted September 13, 2005 Share Posted September 13, 2005 ..Over time its like shot blasting your turbo blades. it's also like grinding your valve seats and piston rings. I suggest some leakdown tests before/after using a 'performance' filter, especially if you've just rebuilt your engine. It's an eye opener.

Soonto_HAS_soop Posted September 14, 2005 Share Posted September 14, 2005 That's all good information, so add it to your sig so that it doesn't have to be repeated over and over again. It's getting boring reading every thread about engine performance, that then goes to "stick with the standard airbox", we all know, and if we don't we can search. You don't like induction kits and what they can do - WE ALL KNOW!! We get reminded every other day...... Link to comment Share on other sites More sharing options...

Ian C Posted September 14, 2005 Share Posted September 14, 2005 I think this argument is diluting the thread.
