Looking good! Small side note- your engine stand, does it have a screw thread rather than a hydraulic ram? Looks like hard work! Yep.. it's from the dark ages think Noah used it for building the ark, it's proper hard work and tbh I'd love a hydraulic one. But that's 100 quid I can't spend on summat else haha |

A word of caution - your pipework layout into the wastegate is somewhat "sub-optimal" from a flow perspective so erring on the side of caution spring rate / boost -wise is probably wise. With your 11 psi spring in that, I'd expect somewhat more ... Looks good though :-) What would you say is optimal in this situation ?? Asking as i’m about to turbo something with the same sort of manifold into turbo situation . mat88 , hopefully you don’t mind me asking questions on your thread ? Loving your work so far !! I'm aware it's not "ideal" but I'm limited for space limited for budget (didn't really want to buy 2) and definitely limited on ability haha... The pic you've done showing 2 down into one is sort of what I wanted to do.. but didn't have the pipework to do that.. and couldn't see a cheap easy solution to getting 2 tight 90 degree bends right diameter especially not quickly (I'm a bit like a child and would rather do summat twice than wait for stuff coming, I know thats not a good mentality but that's life haha) Il prob stick a 7psi spring in and see were we go.. il have fuel available for the extra boost and will be able to map it accordingly if it creeps up to 10/11psi.. But thanks for pointing it out. It's all learning and if no one said anything no-one would learn anything. Me especially haha |

Interesting thread. A few things- I’ve done the 5” gas pipe through the crossmember with some bracing to run an exhaust through before. Works well, I’d definitely recommend it as a problem solver as it’s easy to brace up the subframe or whatever aftwards. I’ll be utterly amazed if your exhaust doesn’t crack. I really think you should have put a flexi in where you originally planned to account for all the different material expansion rates you will have going on, especially with it being a v8. I’ve also done the making oval tubing by cutting and welding. Pressing to shape really doesn’t work very well, cutting and letting in some flat is the way to go. Thanks, the thick wall tube is looking like the solution to the clearance on the subframe. Il probably do it once the engine is back in and I've decided were the downpipe will come out And I agree about the Flexi to a certain extent. I will more than likely end up putting a Flexi in the long side before I wrap it. Cheers |

Yes, 2 into 1 as expertly drawn  would be better but only if you can package it. No point having the perfect solution if it doesn't fit in the car ! The way you've made it means the wastegate is sitting in a low pressure zone created by the two exhaust flows. As long as you're aware and go suitable light on spring, you should be OK. Just didn't want to hear your engineering marvel had energetically dis-assembled itself on the dyno due to the boost being a bit higher than expected  |

Yeah I'm aware it's obviously going to be sat in "dead air" so won't work as well as if it was in direct flow.. but like you say no point in it all being perfect if it won't fit in engine bay anymore haha And don't worry if it explodes in catastrophic fashion on the Dyno. Il make sure it's being videod at time |

You should have asked me about designing the pipes and locating waste gate. Then all you'd have do, is just do the opposite! Keep up the good work, it's a great thread (a V8 IS200 is right up my street) and especially with others chiming in with practical advise. |

Well it would apear I've basically done the polar opposite of what I should have anyways haha... Joking aside what I have done is best I could with a zafira exhaust ten quids of flanges and a bit of bad welding  so wel see haha. And cheers. Lexus should have built them like this from the factory. They would have slayed the equivalent M3 at the time and look better with all the trd bits on too (in my humble opinion, don't want to upset zee Germans).. Hopefully a slight update tomorrow if I get an hour. Although Mrs has started with the major aches and pains and is about ready to drop.. so wel see what comes first. More progress or my little un lol |

More progress or my little un lol I must agree with you. Lexus should have built them with the V8 or at a minimum the IS should have been originally offered with larger six pot. It really was a shame as the 2.0l IS was a far better car than the equivalent E36/E46 320. I had a Sport for several months when they were new (twenty years ago! ) and loved it even with sub 160 bhp and 24 mpg. Rock on! |

Yeah. Even the is300 was a bit wet especially since 99% were autos (don't even think they came manual in UK)..
But yeah the 160bhp 2.0 is pathetic. Makes a lovely noise, smooth as silk but dog slow.. hopefully this swap should reset the balance in favour of performance haha.

Afaik only 'murica got the manual is300, and Japan of course, they always keep the best stuff for themselves |

That wastegate might not be too bad , looking at the increase in cross sectional area the gases will slow down a bit , which will help them make the turn into the gate .a refinement at a later date is you can cut the gate hole in the turbine housing and weld to that , so its in line with the flow .

I have thought about getting the wastegate welded directly to turbo if needs be. Again space is tight around the turbo so might not work.. think best bet is try it as is and send it haha.

Yeah that's the one.. all my mates have been sending it me this morning haha.
If they like that one. Theyl love this one haha. (Although I get the feeling when the hx50 spools up it may become a bit lively)

I always thought that the IS200 was a good looking car crying out for a good engine. Well done that man!! I am bookmarked and am in for the slightly bonkers ride!! Same, same. I really fancied one back in the UK, until I got totally underwhelmed with the performance specs. The V8 should have been a natural choice or, failing that, a proper straight 6. Great thread, wonderful attitude, good luck with the new offspring and another bookmark. |

I promise il make this one more proper than the last haha.. just taking me a while longer with actual adult life taking up my spare time. But it will be worth it once it's done |

Great to see you're old one on PH. And nice to see the positive comments it received bar the usual one or two that can't see past a German badge, but I love those negative posters...you couldn't help but feel better about yourself! |

Yeah. Tbh it's been for sale for a while
He paid 4k for it and from what I can see it's same as when I had it. Hence it taking a while to sell... That being said even at 5k I don't know what you'd buy that would match it for performance/comfort/fun..
And the German brigade don't bother me haha. End of day I build/own stuff I like for whatever reason.. I'm not a brand snob or follow trends (I had a mk2 vr6 Jetta when they weren't cool haha) and BMW's just don't do it for me.. but some people will never ever see past the badge. It could say perodua on it for me I'd still like it lol..
