Turbo or swap nonsense is for hobbyists that are willing to spend half of their life in the garage for no money. If you are regular bloke best invest your money in gold instead of used rotating machinery.

I say do a swap. Turbo v8 is always awesome but it's expensive. If you swap a 2jz in there are way more parts available for forced induction and alot more info on it. Also think about fabrication isssues with the 1uz. Alot of people I've seen weld their own manifolds and stuff. Swap in a 2jzgte and single turbo it. If you want to keep the v8 I'd supercharge it as it is "easier" on the engine with it's progressive engine loading.

I am pretty sure this guy is not asking for investment alternatives...

OK to give you a straight answer, It is ok to boost older engines as long as you do it right and you only give it a moderate amount of boost. As long as your air/fuel mixture is perfect and you run no more then 10ish psi, it'll be fine.

DO NOT do a 2jz engine swap (sorry sc300 guys, I still love you too). The 1uz is actualy a much more well built engine but yes there arent as many aftermarket parts for them. The problem with the 2jz swap is that you will end up spending more money in the long run and end up with the 2jz-ge which is actualy less capable of handling higher psi than the 1uz.
BTW, this does not mean that the 2jz-ge (not 2jz-gte) is a bad engine, its just not as good as the 1uz.

I know a turbo sounds like a great idea but to be honest, its not just a bolt on and go, kind of system. It requires a lot of time money and dedication. And even after the whole thing is installed, you still have to constantly tune it.

Honestly, start with other thing first like intake and exhaust then after that go on the internet and read, read, read, read, read, read, read.

Yeah have to disagree with you on the GE handling higher PSI. Boost pressures north of 40PSI is low? Bottom line, you'll never max out a 2j for a street car. Never.

EUROJulian

Your point?

MattStarr

well, yes if you replace the pistons, otherwise you'd be running such a high compression ratio your engine would just explode. Mind you Im just basing my thoughts on common engine knowledge. Im not that familiar with the n/a 2jz, Im more of a 1uz junkie, so my appologies if im just talking out my a**.

Anyways, you can send 40psi to the 1uz too if you replaced the pistons.

Oh okay fair enough, if we're talking stock for stock you're probably right. However, just swapping the HG on a GE (cake on an I6) to a GTE headgasket drops the compression down to around 9.1:1 which can hold about 17psi on pump. The stock pistons and rods are good for plenty of power passed that as long as you have the right fuel

Not to sound like a douche but if your asking this many questions, boosting isn't for you.

^ Which is why I recommend that Book. PLEASE take my advice and read that cover to cover. You'll learn so much

If you are planing to boost the 1uz using a turbo you really have to love it because its not cheap. I got a quote to build two manifold to a single turbo at a local shop for $1600 stainless steel down pipe would be another $200. Turbo would be about $800 brand new (might find it cheaper used). charge pipes will be around $350. Intercooler about $200. Waste gate and bov about $400. Add another $500 for oil lines, vacuum lines, nuts bolts, fittings, fluids, etc. Now the real problem is that all those prices are for parts only. But the good news is that your 93 has stronger rods according to lextreme which is a real good thing.

klaus thanks for the reference to that book--that is exactly what i need

something to teach me about this topic from the ground up.

Thanks again everyone ive learned quite a bit here-----good starting point.

And coolal yes the 93 rods look like there twice the size of the others---------very interesting. I am confident in my engine----it is very strong and I think it is still pretty young at 140 000+kilometres. But im going to do my homework before doing ANYTHING at all to the engine.

Thanks again everyone----everyone except VIETUNIT of course.

coolal hopefull that cost can be cut down a bit by sourcing out some good used parts----and maybe a little fabricating and resourcefulness.

My mechanic is also a good guy--------he would do his best to keep the cost to a minimum-----also I would be able to lend him a hand and learn a few things---be a part of the whole process.

Thanks

From experience, I dont think 5k would do it. You will need at least 7k, an excellent mechanic, and a lot of patience.

My budget was 6k for my v8 project.....so much for that, I must of went pass my budget a couple of times and it is still not running yet...

Man that sounds a bit scary----over 6 k and still not running?

I hope it works out for you

Good luck
