Thank you for all the information. It is a lot to think about, I really do appreciate it.

THe oil sump issue seems easy if you have it built with quality. and the cooling I am not concerned on.

I am not sure what problems I would have with torq or drivability with a gen4? Please elaborate.


"You are talking about changing a ST215 3SGTE to RWD.
So youll need different/custom intake manifold, custom coolant lines, custom engine mounts, will need to remake/modify the engine loom, modify the sump and, custom flywheel/bellhousing/clutch/starter, W58

all the bolds I will have to on any motor swap.

So yes for the 3sgte I will need to rotate the intake manifold, but I can weld that my self. a w58 tranny but thats not much clutch flywheel all easy too, bell housing is hard to get, but there is a shop here localy that makes them. I need to price it out though... I have not called yet.

I will be running stock ecu, with stock internals, just moded to fit, I am not sure why that sounds so bad.

and if i get a BT, put after market pistons $500, rods $400, machining work $300 ems and tune $1500 etc etc thats crazy money....

Yeah, its a pro drift car, but its a good example.... of a pro drift car, not a reliable weekend drift car.

1UZ, no I have not, tell me more

I am still not seeing the expenses you are with the gen4 VS BT. I would like to look at it more with everyone and keep getting opinions.

gen4 just turning up the boost a little I will have 240ish to the wheels, completely stock.. and can easily have more.

so lets compare and contrast. If I wanted over 200+ rear wheel HP for either setup.

Both set ups would need custom coolant lines, custom engine mounts, will need to remake/modify the engine loom since I have to get that for any motor swap.

If I where to go Black Top. Motor cost about $1400. I would still need to get after market pistons $500, rods $400, Turbo $500, injectors $300, fuel rail $200, FPR $100, wastegate $200, custom DP $100,machining work $300 ems and tune $1500 (cheapest possible) that's all I can think of.

Total $5,500

VS

gen4 motor $1300 custom intake manifold ( re weld it or use stock TMIC) so free or I re weld it for free. custom coolant lines $200 for material. leave it tilted which I am fine with, or modify the sump, re weld it which i can do. W58 transmission $300, flywheel clutch kit $400, I cant think of anything else I would need.

Total$2200

My neighbor has had a gen4 in his car for a few years now. Its across the street from me, he has one in his celica, and we have taken it apart to rebuild it. He is an electrical engineer, and built his harness. and he will do all my electrical. So its no problem at all.

His motor with just a boost controller intake and exhaust dynoed at 255 with the boost barley turned up (15psi I think). I am not sure where you are getting your numbers with "cant get more then 240 rear wheel hp" on that turbo. I know its a small turbo, but it works pretty good for the HP rating I am going for. And if I want to swap it out later, I could for a gt28rs or another small turbo which are not very expensive and would be an easy swap. But like I said before I am only looking for 200-300 rear wheel hp anything in that range will be ok in my book.

The rods are thinner then gen2 and gen3, but I am not looking for over 300hp, so it will not be a problem. And their is really no evidence that I have seen, for rods failing sub 300BHP.

I will have a vented hood, so the top mount air to water intercooler will be great.


the sump will be something more difficult. but again that is only if I want to make the motor not have that slant. And to be honest the slant does not bother me, if it does down the line. I have either tear it down and re make it. Or have one made. either way not a huge problem but probably one of the harder parts of the build other then the rearwheel bell housing.

I made a price chart above, and the money still shows to much higher cost in getting a BT into the 200 rear wheel hp range. I am very supportive of everyone's opinions and Would really like them to keep coming. but show me prices and facts. write out a price chart of what you think it would be. cause you keep just saying its expensive, but when i do the math. I am just not seeing it??? look at my chart above, and please give me your example so I can more clearly understand your point.
