Guest jk_supra Posted October 15, 2006 Share Posted October 15, 2006 im new hear and i no you guys probably hear this all the time but where can i find tuning parts for an NA supra? i dont want to do a turbo conversion as i want the simplisty of the na and the noise, im looking to get around 300bhp, was thinking of an exhaust manifold, removing both cats, cat back exhaust, induction kit and heat sheild, uprated clutch, lightweight flywheel and pullies and making the rest of the power up with nitrous. how much nitrous can be used safely on the na engine? any advice appreciated cheers Quote Link to comment Share on other sites More sharing options...
Daston Posted October 15, 2006 Share Posted October 15, 2006 for the price might as well go for a turbo will be more reliable than nitrous and far more drivable. Quote Link to comment Share on other sites More sharing options...

Sadly you are now going to be bombarded with loads of replies saying if you wanted more than stock BHP you should have bought a turbo, yawn. I have been loking at this too and there is not a lot out there in the way of bolts ons. Do a search and you will see this subject is well covered. I reckon though there is room for power increase. What you have suggested sounds good but nitrous is not so cheap to run. Was thinking about a custom intake plenum and a larger throttle housing, Q45 maybe, but then because of the nature of the ecu you are going to be into fueling problems I think. reckon your suggestions are as far as it goes without big wads of cash and small amounts of return. Good luck mate and dont be put of with the get a hairdryer remarks. Quote Link to comment Share on other sites More sharing options...

Where has all this theoretical anti TT stuff come from tonight? I own a TT, i like NAs, so shoot me. JK_supra, a quick search will yield a fair amount of info about more power from the NA, or you can look on the US sites, as they have a lot of hi power cars there too Search Dave H for example Quote Link to comment Share on other sites More sharing options...

It's just like a broken record though, everytime a new NA owner comes up on the forum and asks this loads of replies appear along the lines of "buy a TT". One bloke even said the other day that a NA is not worthy of the Supra badge. WTF is all that about? For the record I like them both too.

No worries Shane I didnt see that, please be aware this is not the opinion of the club in general. Usually it is tongue in cheek humour, but some folk do take it too far. Having driven (but not owned) both, i can say the NA is capable enough Quote Link to comment Share on other sites More sharing options...
Jake Posted October 15, 2006 Share Posted October 15, 2006 Isn't the "Buy a TT if you want 300bhp" opinion perfectly valid though? I don't understand the logic of buying an NA and then throwing a lot of money modding it in a vain attempt to make it a similar power output to the TT.

I don't understand the logic of buying an NA and then throwing a lot of money modding it in a vain attempt to make it a similar power output to the TT. For the same reason thet you buy any car and then mod it surely?? Half the fun of modding a car isn't just the BHP output at the end but actually piecing everything together over time and changing it all about - like TT drivers who go single looking for 500bhp - why not buy a 'rari or a Lambo in the first place etc.? As to N/A power, try Lucifer - he has a naice exhaust manifold which is reported to be good for around 10 brake. + the mods listed already and ad in some cams perhaps. Unfortunately 300bhp is somewhat unrealistic without very, very deap pockets Quote Link to comment Share on other sites More sharing options...

Unfortunately 300bhp is somewhat unrealistic without very, very deap pockets Buy a TT is a perfect option. It makes financial sence. Some who go single do it because with the amount it costs to run silly power is still LOADS cheaper than buying another car e.g. "lambo" that is similar.

ChrisSZ Posted October 15, 2006 Share Posted October 15, 2006 Likewise, if you only have £4k capital then an N/A makes sense - you cna then spend in smaller amounts tuning it! I'm sure that the guy didn't ask "Which Supra should I buy for 300brake" if he had done so tnen "Buy a TT" would have been a logical answer Quote Link to comment Share on other sites More sharing options...
Nic Posted October 16, 2006 Share Posted October 16, 2006 I have 2 x tubular NA exhaust manifolds available if anyone is wanting one. See pics here. http://mkivsupra.net/vbb/showthread.php?t=83236 Quote Link to comment Share on other sites More sharing options...
Max Headroom Posted October 16, 2006 Share Posted October 16, 2006 I have an NA, I love it to bits. I am doing all the things I can do to get a bit more power from the engine (aftermarket exhaust, full decat, stock airfilter) The power from the engine is enough for me, at a recent RR I had a readout of 220bhp against a stock TT which had 300bhp. To me 80bhp difference is nothing in the grand scheme of things and to a certain degree the power delivery on the NA is more useable in a day to day car in that its more linear than the TT. But all said and done, if I was really truthful then I would love to have a TT but I am happy to own a car the exhudes a certain carisma that makes people look twice at the car and IS a "high performance supercar" in either the NA or TT guise.

Guest jk_supra Posted October 16, 2006 Share Posted October 16, 2006 so whats all this bout supercharger kits for the na, did a search on google but couldnt find anything:search: Quote Link to comment Share on other sites More sharing options...
Nic Posted October 16, 2006 Share Posted October 16, 2006 so whats all this bout supercharger kits for the na, did a search on google but couldnt find anything:search: There are Supercharger kits available in the US for the IS300 which is fitted with a VVTi 2JZGE engine. Unfortunately these are not a straight swap on the non-VVTi 2JZGE Supra, as the distributor is in the way. To fit one you would need to remove the distributor and convert to electronic ignition. http://www.lextasy.com/LMS_IS300_supercharger.htm http://www.lextasy.com/images_products/IS3_0011[1].jpg Quote Link to comment Share on other sites More sharing options...
RobSupra Posted October 16, 2006 Share Posted October 16, 2006 I bought my na for the simple reason that i could not afford the tt when i was looking for a supra, its true ive probably spent more now than what i could of bought a tt for BUT i havent had to spend a big wad of cash in one go, it`s been a gradual process and over the few years of ownership ive managed to get tt power out of my na + plenty more potential. Ive posted this very question myself in the early stages of ownership (not on this site but others) and i have had the very responses you talk of, some are all in good humour, some more serious but dont let it put you off, as you say a decent exhaust system with both cats removed will be a help and the heat shield a must if your going to run aftermarket filters, also try finding someone who can fabricate you a custom intake pipe and remove those 2 horrible silencer boxes, i noticed a difference when i done this to mine. removing the aircon and viscous fan will take a bit of load of the engine but dont expect huge noticeable power gains from this. I think 300hp is a little out of reach without mega bucks like some have said but getting a bit extra out your n/a shouldnt be to much of a problem.

SuperSupraNA Posted October 20, 2006 Share Posted October 20, 2006 far out that supercharger kit is pretty impressive, looks pretty clean. anyone know of any cars using this at the mo? I thought the two boxes from the intake on the n/a were the airflow meters? are they just silencers and can be safely removed? Quote Link to comment Share on other sites More sharing options...
ChrisSZ Posted October 21, 2006 Share Posted October 21, 2006 are they just silencers and can be safely removed? Resonance chambers and yes, they can be safely removed - although you'll need to find some way of re-attaching the vacuum hoses Quote Link to comment Share on other sites More sharing options...
SuperSupraNA Posted October 21, 2006 Share Posted October 21, 2006 any suggestions on how to do this? what exactly do the vacuum hoses do? Quote Link to comment Share on other sites More sharing options...
RobSupra Posted October 21, 2006 Share Posted October 21, 2006 best bet is to get someone to fabricate you one, its not a big job and while there at it they could weld some fittings on to connect your vacuum and breather pipes. Quote Link to comment Share on other sites More sharing options...
ChrisSZ Posted October 21, 2006 Share Posted October 21, 2006 any suggestions on how to do this? what exactly do the vacuum hoses do? One goes into the cam cover area (not a clue what it's for ), the other is a crank case breather - mine's vented to atmos now, but you also need to plumb in the air temp sensor. My setup looks like this;- Quote Link to comment Share on other sites More sharing options...
