Well, I've blown the engine in my 87 conquest tsi. I'm going to pull the motor here pretty soon and see if it's repairable or not, but if it isn't I'd like to know if anyone knows a good motor that would fit for a upgrade?  I'm looking for something that wouldn't be too heavy on my pockets, but my endgame I'm pretty sure it would fit, but one of the late 90s supra twin turbo engines. For now though I'd like to put a upgrade in it that won't be as hurtful on my pockets at the moment, any suggestions?

With any luck you just blew the head gasket and no other problems exsist.  If youre wanting a 2JZ take a look at e bay.  Theres an importer that sells motor, trans, and ecu for less than its costing me to rebuild my 2.6.  Youll need mounts and driveshaft off the top of my head. Theres a good section on here about swaps. Lots of good info.

Plan to spend $4k to jz swap unless you want automatic trans or find a smoking deal. You'll need: mounts, radiator, ic and plumbing, exhaust, driveshaft, as well as the engine, trans, ecu, and harness.

We've been looking at this, did you have to swap the tranny as well or is there an adapter plate to fit the tranny for the car?

Mine has a 4L60E automatic tranny.  I do not know of any available adapter plate to use the stock tranny.  You need to fab a custom support bracket for whatever you use.

Alright, after several months of research and looking and trying to find the best pricing to get my Quest back up and running, I finally have my game plan and the start to it. I'm keeping the G54b engine, take away the balance shaft and balance the engine. I actually found a short block here locally, I got lucky it didn't have any main bearings spun, but soon it's going to the machine shop after I have the Master rebuild kit which I'm ordering tomorrow. I was going to bore my pistons, but my previous pistons are still almost perfect so I'm going to run the engine a bit more before I bore it out. I need a new radiator and battery which isn't a big deal, I'm also getting non-jet valve head before I put the engine back into the car so I won't have to do it with less space. Once it's back up and running again I'm going to have someone build a 2.5" exhaust and I'm thinking a aggressive borla muffler.

Okay, I took the short block to the Machine shop this morning to start the work on it.

Had some problem with a part order, but situated.

Just a heads up.

The rock auto radiator might not have the radiator fan sensor bungs on the bottom for the radiator.

A good mom n pop shop can remove them from the old rad and braze them in the new one

If your looking for performance exhaust. On the dyno the 3 inch out performs the 2.5.

I've heard 3" is too big for our motor to run full performance for some reason... maybe with the stock turbo... Not sure what exactly the problem he said it was, but I heard 2.5 was better and maybe go into a 3" out the end... but if that's wrong I may go 3". I'm looking for big sound too.

I want to say he was saying there was some type of fuel problem with a 3" exhaust. Could be wrong.

The only negative thing I've ever read about 3" exhaust, came from TEPs website.  

Go ahead and get a 3" while you're upgrading....

TEP is the only one that said that.

3 inch out performs the 2.5 on our cars for just about every dyno sheet I have seen.
3 inch Is the best sounding exhaust In my opinion.

I hope you are getting the right parts.
Are you sure the Master kit you ordered is for the turbo 2.6?
Many times you end up with flat top pistons which is a no-no.
I see you are ordering a non jet head from Randy. You also should go with new valves and springs.
You really should call and talk to Randy and have him advise you on parts.

If you are buying new pistons, don't forget they need to be installed on the rods by a machine shop and that they should go ahead and rebuild them with ARP rod bolts.
You may want to get some ARP head studs too.

Are you building this engine or having a shop assemble it?

Yes, I made sure it's for the turbo application.
I was planning on getting new valves and springs with the head I got from Randy, I've already tried to call and talk to him, but he's out until the second of next month.
I already have my block in a machine shop getting balanced and worked on while parts are being shipped here at the moment. I plan on replacing the head studs as they get stretched from the first use. I'd never reuse head studs.
I've been building the engine myself, with my old man. He's a master mechanic, I'm a apprentice.

My father from the start of me getting this car told me he didn't know a thing about this particular car or engine, he told me he doesn't think he's ever worked on one personally. He was the one who suggested I actually try to find a forum for questions he couldn't answer, I think the original owner had told me about a site or group called starquest when I had bought the car, and here I am haha.

Make sure you get the block decked at the machine shop.   So you have a flawless mating surface for the head.....

Glad you have help.
Until you get the crank, pistons and flywheel, there really is nothing to balance except for the rods.
Make sure they also attach and match mark the pressure plate when balancing the flywheel.

If you are interested, put up your email address and I'll send you a spreadsheet from when I used to build these engines.
It was mainly for budget and blue printing purposes.
I have a lot of part numbers too.
