Definitely keeping spare guards but these aren't anything special, just the same as normal lancer. Weirdly the bonnet has rusted in the same spot about 30cm to the right of the hinge just like my one, even though mine is the later shape bonnet to match the evo 5 style headlights. I didn't think this generation had roof rust problems like the evo 1-3 did, but this GSR is really bad in the roof. The rest is actually pretty good, except the bonnet. Not sure why there is a bonnet butt hole though. Still learning about Mitsi's EDIT: just realised you were talking about the radiator support panel stuff. Yep that was my thinking. This one has some surface rust on the lower support but worth saving. 1 Quote Link to comment Share on other sites More sharing options...
shrike Posted December 30, 2023 Share Posted December 30, 2023 Check the rear mounts on the subframe that go to the mustache bar, they have a habit of cracking/rusting out Had to get mine plated and welded up on my Gsr when I had it Worth doing if your going to have it out anyway 1 Quote Link to comment Share on other sites More sharing options...

~Slideways~ Posted January 21 Author Share Posted January 21 Alright so this is the 4g93 GDI turbo engine I bought for bugger all, with the assumption that the block and crank would be the same as the GSR 4g93. Supposedly only 125k on it. Only ever automatic so hoping for good condition block. Basically the plan is to bin the gdi stuff, which is all problematic from what I've heard. It's a weird high comp, direct injection turbo. Lean burn 165hp, the head is completely different as expected. Then get some forged rods, which is the gsr's weak point (well the first one lol). Plus the GSR pistons I got with the green parts car. So here it is...next to the white car I really should be working on instead of stripping this engine: Coil on plug, i wonder if they are any good? A bit too long for the mivec head but could be modified. Huge plastic intake removed, intake ports being here is still so strange to me: Pretty clean in there, thats a good sign. Gross egr stuff. Turbo is smaller than a td04, could be good on a turbo Nissan mini thing. Manifold looks very similar to the GSR one but this has a cast tube thing for the egr port. You can see it on the right hand side of the exhaust manifold, running along the front of it where it goes to the downpipe to suck in crap. Head off, it's super clean! Valves are carbon'y but i was surprused they are reasonably big, will compare to gsr head and mivec head out of interest: Now the good part, the bores look brand new! Well at least I assume these are factory cross hatch marks? Unless it was rebuilt? It feels smooth but those cross hatch marks might mean it doesn't need any machining? Compared to the gsr block from the green car which looks and feels like it was honed with 80 grit can literally catch my nail on all of the scratches. Wtf. But that was always going to need a lot of work, obviously a home job rebuild. Surprised it managed enough compression to bend the rod it came with haha. So yeah, this gdi block looks great! The head gasket fits the gsr 4g93 block perfectly and visually it all looks identical. Good thing about going 4g93 is parts are cheap and gearboxes don't cost $1500 plus. Most people give up on the 4g93 because it needs forged rods. But China to the rescue there. 7 Quote Link to comment Share on other sites More sharing options...
Stu Posted January 21 Share Posted January 21 Because Im a starlet tragic I am intrigued by that small turbo given that alot of 4e's end up with tdo4's on them. Is there a part number on it so I can look up some specs? Quote Link to comment Share on other sites More sharing options...

~Slideways~ Posted January 23 Author Share Posted January 23 Just thinking out loud on this, the plan is still to keep it low budget pick a part build type thing and see how good I can make it without a big budget. The idea of using the Mivec head is the most interesting part, it should be able to flow lots at the top end while the the 'normal' cam profile should make the bottom end pretty decent. A bit like Vtec turbo's make stupid power, but this should also need a big turbo to keep up. i.e. if I use a TD05-16G type thing, the top end will probably trail off which defeats the purpose of the mivec cam profile. I have no doubt it can make lots of power but the budget means I need to match it to what the rest can/could in theory handle. The unknown is how strong the factory pistons are and how much power the gearbox can handle. Pistons: These are probably fine as long as there is no detonation. The rods bend at around 250hp (12psi or more with the td04) before people find the limit of the factory piston in 4g93 GSR turbos, but I don't think 4g63 evo engines have anything special piston wise and people seem to be able to 'safely' make 400hp / 300kw before forged rods and pistons (not sure if flywheel or at the wheels). Later Evo's seem to have quite thin rods too so again is the limit the rods not the pistons? JZ's can make lots of power on stock pistons which are just cast things. Gearbox strength: The transmission code makes it sound like it'll be similar to Evo 1-3 gearbox strength, maybe more? But it has a different design to those early gbox and transfer case designs, much like the evo 4-9 gearbox just not as big. Turbo choice: I've been really impressed with the response of a twin scroll turbo. The relatively big Holset HX35 12cm jobby I used on the 1jz responds instantly. The 12cm exhaust housing might be a bit big on a 1.8 although it has been done. There are 10cm and 8cm twin scroll versions but harder to find and get more expensive. Plus to do it properly the cost and complexity goes up with the need for 2 wastegates. An HX35 can be anywhere from $500 to $2000. So in theory, the cheapest 'pick a part' option would be a twin scroll evo td05 I see these come up quite cheap some times. I'd still have to make a manifold to suit, but can maybe get away with the internal wastegate. TD05 2nd hand around $300 to $800 The turbo needs to be able to breath lots in the top end with the 'big cams' of the 4g92 mivec head, so a stock td05 evo5-8 type thing might struggle. They seem to be limited to around 320-380hp on a 2L 4g63 (just general internet comments). These new Garrett G25-550 (550hp) jobbies look great but expensive and I don't like ball bearing turbo's ever since I had an expensive BB GT28 die and the only option was a whole new centre so basically throw it in the bin. Holset's are built like brick shit houses, basic rebuild in comparison. But quite large housings so packaging will be hard and internal wastegate doesn't work well on petrol engines. So do I have a responsive 220kw at the wheels td05 type thing or a 300kw big holset (still relatively responsive) to make use of the mivec cam? I used to have a TD05-16G single scroll turbo (evo 3 generation) on a 1.6L 4agze making 220kw at the wheels, that was 20psi and probably all it had, it was amazingly responsive on the 1.6L. The only thing better was the BB GT28, but it died before I could get more out of it (needed more fuel). This awd lancer will be 350kg heavier and AWD stuff to lug around, so I reckon it needs 250kw at the wheels at least which I don't think a td05 will do. Unless it's a -20g or something, but less easy to find and I've never tried one. Quote Link to comment Share on other sites More sharing options...
shrike Posted January 23 Share Posted January 23 Chinese turbo that you've disassembled and reassembled to confirm quality control? 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 23 Share Posted January 23 I had an Evo based td05 20g it made 200kw at the wheels at 4000rpm and 245kw at about 6500 rpm on my pretty stock 4g63t, on 18-20ish psi. I like my mid-range performance on the street, it probably needed more camshaft if you wanted to up the rpm... I reckon this was the sweet spot for stock drivetrain AWD Lancer, no need for a twin plate and the problems that go along with them. Stock cast manifold, 720cc injectors, Walbro in tank pump and reflashed Mitsubishi ecu. Edit -it made 235 on stock cams and 257 wheel kw at 6000rpm on the old spec kelford 264's the 245 number in my head is my starlet dyno plot..

Honda Ass Dragger Posted January 23 Share Posted January 23 Go the HX if MIVEC is anything like VTEC it will breath. My Civic with a 1.6 B series has the Xonarotor 5757s I've got with a .82 rear is fully on song by 3500 and holds till 9k 182KW at the hubs on 7psi Quote Link to comment Share on other sites More sharing options...

Hard to really know the quality control just looking at it I reckon, except for maybe crappy casting and machining. I once had a T3/04e type chinese thing, it spooled well made good power. But lasted about 1000km's, the thrust bearing appeared to be made out of very soft brass and it wore away fast then ate the compressor wheel. The journal bearings looked ok. If I took it apart I wouldn't have been able to tell the quality of the brass. This was ages ago though so maybe things have improved. On the other hand I have a Kinugawa td05 on my Safari, after a bunch of research on Ausy 4wd forums and it has held up really well. That was a reasonably expensive 'knock off' though I guess.

Being an evo 4 you'd be using the twin scroll stuff right? I don;t think I'd be able to use a stock 4g93 manifold unfortunately, since they have the tiny td04 round outlet flange. PS what's happening with that starlet? I remember looking at it years ago and thinking 'man that's cool'. Now that I'm old and mature, I'm thinking 'man that's cool' Quote Link to comment Share on other sites More sharing options...

I was more meaning make sure no shit that hasn't been cleaned out and everything balanced and put together torqued up etc They tend to be older design turbos and the main downside can be as you said materials or quality control from an assembly perspective Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 24 Share Posted January 24 Yip twin scroll, it's worth the effort on a 4 cylinder. Not so much on a 6 though.. Still got the starlet, it's doing a great job of keeping the dust off the floor in my garage.. hasn't been out in anger for years. I have considered maybe selling that and my mini so someone gets some use out of them.. The kinugawa stuff is alright at a price point, but if going td05hr I'd go OEM for sure.

Honda Ass Dragger Posted January 24 Share Posted January 24 I recall many years ago there was a Blue Lancer in Wellington that was on cover of NZPC that was a FWD Mivec Turbo and made serious power. The 1.6 Mivec Cyborg motor was rate for 10kw more than the B16a so I'm expecting it must breath Quote Link to comment Share on other sites More sharing options...
