bdh1987 Posted March 31, 2013 Share Posted March 31, 2013 Hi all, was wondering, Had my supra for 2 months now so been thinking about what im going to do to it. Well eventually im going to go from stock BHP to around 600bhp. But until then i was going to see about getting a powerflow exhaust system. If i got one now, would it be ok with the 600bhp later on down the line or would i need to new exhaust all together? cheers, Ben. Quote Link to comment Share on other sites More sharing options...
Noz Posted March 31, 2013 Share Posted March 31, 2013 The size of the pipework is more important than the actual make of the system. Quote Link to comment Share on other sites More sharing options...

A 3" all the way through would handle 600 horses fine. However, iirc you would also need to get a 3" down pipe. On stock turbos, make sure you put a restrictor ring in the exhaust too, otherwise you will find yourself going single before you planned to when the turbos go pop. If you have an NA, however, a 3" system will be LOUD, especially with no cats in. Personally, if you're looking for a supra specific exhaust, Whifbitz systems are highly recommended here, with a lot of members now using them.

sideexitsupra Posted March 31, 2013 Share Posted March 31, 2013 Edit: beaten by Listy Would suggest you speak to Whibitz. They have a range of exhausts in stainless and titanium with different diameters and choice of number of silencer boxes. Paul will recommend the right one depending on the level of noise you want.

Westy Posted March 31, 2013 Share Posted March 31, 2013 Just buy a Bootlogic 4" and be done with it!lol! Best sounding exhaust IMO. Quote Link to comment Share on other sites More sharing options...
Dnk Posted March 31, 2013 Share Posted March 31, 2013 Do you have j spec or UK spec ? if UK you won't need a restrictor ring on the twin set set up Quote Link to comment Share on other sites More sharing options...

Benjy Posted March 31, 2013 Share Posted March 31, 2013 I've got a stainless 6-2-1 manifold and 1st decat for sale. Made a massive difference when I fitted that and a 2nd decat. Also got an HKS Mushroom filter up for grabs too. Quote Link to comment Share on other sites More sharing options...
listy Posted March 31, 2013 Share Posted March 31, 2013 My car is a non turbo Jap import Still wont need a restrictor ring then However, bar sound (more noise) and looks, an exhaust won't make much difference on an NA in the great scheme of things. You would be better of spending the money on a good service and fuel IMO. Slightly off topic, but 600bhp is a big figure for NA-t. Most aim for circa 450 for NA-t, although there are a couple on here pushing towards 600. If its power that you want, then a TT transplant would be the easiest solution, and least hassle. And you could go single from that after wards. 600bhp isn't cheap either, not reliably anyway. Have a search and browse through the NA-t, NA-TT, and Single conversion threads, to get a better idea of what you want. Quote Link to comment Share on other sites More sharing options...

Yeah, money aint so much of a big thing at the moment because once i got the looks sorted (kit and interior) im going to take it off the road whilst i get the engine done Quote Link to comment Share on other sites More sharing options...

Benjy Posted March 31, 2013 Share Posted March 31, 2013 My NA was around 230bhp with double decat, HKS centre and rear pipes, HKS induction kit and HKS plugs. Charlie at SRR told me I'd get no more than 180. He was amazed to say the least. 600's ambitious for a GE engine. If you're aiming that high, You need to do the same as me and go for a GTE conversion and a big single turbo. Expect to spend £10k doing it properly.

Expect to spend £10k doing it properly. Or buy this one. http://www.mkivsupra.net/vbb/showthread.php?287557-545BHP-T67DBB-Black-Single-Turbo-Supra-6-Spd-Great-Provenance-%A312000 Few tweaks and a remap and should see 600 without too much fuss. Sell the NA and that's even on costs. Plus its already done Quote Link to comment Share on other sites More sharing options...

bdh1987 Posted March 31, 2013 Author Share Posted March 31, 2013 ok, forgetting the 600bhp, how much of a bhp increase could you get out of a N/A, think the standard is around 220bhp right? Quote Link to comment Share on other sites More sharing options...

The book says 220, yes. In reality, most na's are around 180-200 I'm led to believe Quote Link to comment Share on other sites More sharing options...
berg Posted March 31, 2013 Share Posted March 31, 2013 Surely even with a transplant 600bhp wont be very good on the W58? Thats the only thing holding me back as i want to TT transplant mine but for the price of a 6 speed box it works out money wasted and i may aswell just buy a TT6 and have a couple grand in my pocket Quote Link to comment Share on other sites More sharing options...

Depending on torque, the w58 wouldn't last 5 minutes at 600bhp. However, it depends how you drive it. Quote Link to comment Share on other sites More sharing options...
bambisdad Posted March 31, 2013 Share Posted March 31, 2013 If you aim for between 300 and 400hp, you will still have one hell of a quick car Quote Link to comment Share on other sites More sharing options...
bdh1987 Posted April 1, 2013 Author Share Posted April 1, 2013 If you aim for between 300 and 400hp, you will still have one hell of a quick car Yea, i want it to be a bit quicker, maybe 300 - 400 would be ok, but could i get that without a brand new engine? or is it worth saving for a TT?
