Default jumping into something here that i probably shouldn't be

i may be jumping into something here that i probably shouldn't be, but ill find out soon enough.

scenario 1: on a stock EJ22, with stock internals, at a stock compression ratio, am i looking at 6-8psi safely?

scenario 2: on a EJ22T block, with Eagle rods (as i do believe seeing them in a catalog), stock crank and pistons, and stock compression, what kind of boost would i be looking at to not be blowing it up?

which scenario, if either, would be better for daily driving and AutoX'n? im leaning towards the first scenario, but on an EJ22T block (can the NA ej22 blocks take any low boost?)

the project car in question is a 95 1.8L 5spd, awd in which a 97 EJ22 is sitting in a dead chassis, but the engine is otherwise good. for boosting purposes, would it be worth the time money and energy to do an overhaul on the EJ22, boost it to about 6psi, and run that on the stock block? that way, if the block eventually cracks, we could go back to the 1.8L until the Ej22 is transfered to an EJ22T block.

this is assuming that it would be relatively doable to swap an ej22 from an auto car into one originally with a 1.8 and a 5spd.

the goal: daily driving/autox'n fun on a buget.

i know this isnt anything new, but it was started as another post on the CR/boost FAQ, and im sure this isnt a new idea, ive been debating this for quite awhile

auto-x your not going to want a turbo only boosting 6psi... get a 2.5rs motor for cheap you could find over under 1grand... and it will be torquey enough for auto-x... plus with the older years you will be a little lighter and also you should strip the car to bare bones and worry more about brakes and suspension then motor...

that "get a 2.5rs motor for cheap" doesnt happen around here. hell. getting anything Subaru for cheap doesnt happen. i do have the 2.2L in my posession, thats why i am postign about that one. also, there is the availability of the EJ22T block(i have access to -> salvage), and i am unaware of a beefier 2.5L block(except for the STi), and if i was going to do something THAT unbelievebly involved and expensive, id just go with the STi swap. i have 2.2L parts here, and i am more comfortable working with the 2.2's. (thats all ive worked with and i know a guy with an abundence of these hed sell for 100 a piece if i break one)

thanks for the feedback thoh. i understand your point.

I say turbo the existing motor up to 5 psi. It is already torque heavy due to the high compression. 5 psi on the NA2.2 will net you about 180 chp. 7 psi gave me 200-220 chp but it also gave me two sets of shattered ringlands. If you go over 5 psi you NEED to upgrade to 370 cc injectors, intercooler and something to pull timing with.

ok. the intercooler would be done anyways, and the usual WRX injectors (and fuel pump?)

im sorry if i sound dumb here, but what do you mean by "something to pull timing with"

I think you should just go with the STi swap and forget about it. Less problems with compatibility, plus the engine will be more reliable than an older engine, and parts will be more readily available. But I understand it's a matter of money.

Good luck,

Oleg

STock NA ignition timing is WAY too far advanced over 5 psi. So you need to pull the timing with a piggyback or standalone engine management system.

If you are going to boost it, your 1.8l engine will take the boost much better, and you can go higher. Don't bother going to the trouble of putting the 2.2l in there. Put the 2.2l heads on your 1.8l block (bigger ports on the 2.2l heads) and boost that. Do a search for the adventures of Subachad with 1.8T's. You can have a lot of fun boosting a 1.8l, and they are like $75-100 in junkyards. It isn't heads you will blow (either with a 2.2l or 1.8L), it is the bottom end...

If you were to go the Ej22T route, save your money and don't spend anything on Eagle rods. There are a number of guys on this board who have put 20+psi against stock Ej22T bottom ends (using a variety of different heads) with no problems. That block is bulletproof to start with...

make a hybrid. the ej22t bock is the strongest block around. use the block and you can stoke it all the way up to a 2.8. use a set of sohc rs heads and you have yourself a motor that is pretty simple to run and that can take alot of abuse. look up Wedge over on rs25.com he has a pretty sweet hybrid. - IC

p.s i'm running a 2.65l ej22t with my2000rs heads, twe stage 2 cams,and twe ti springs and retainers. i did a dyno break in then did a test and tune. N/A it push 245hp 252tq at the crank. and after i boosted it with my s/c kit i managed 493hp and 522tq @ 18psi crank numbers tho. we'll see what i loose after it running in the car.

Why do people insist on these sort of chest thumping ego gratifying posts in a thread like this? It's pretty obvious to me that this guy is trying to do a budget build. The parts you list cost thousands of $$$ to get together. The starter of this thread is trying to work with what's he's got right in front of him. And BTW, Wedge and his car are verl well know here. He is a 3 digit member number on this board...

i havent posted or been to any meets in a long time, i had to do an ego post. i was trying to demonstrate the greatness of the ej22t block. and my motor only cost me 1400 bucks to build. then i stroked it and the price went up. you cant find anything you need to do a car on a budget at a junkyard. if you need help locating parts let me know. i have some good resources. - IC

arent the EJ18's hard to find junk'd? this 1.8 im getting is the first 1.8 ive physically looked at because everyone who had the choice has the 2.2L (dotn blame them)

ill do a search on Subachad's 1.8T setup, as it sounds different. would it be save to turbo a 1.8 with 103k miles? (i mean without rebuilding and such). also, i was looking at the gap between the head and the "frame" rails. can the head be swapped with the engine int he vehicle or do i have to remove it (the later was suggested by the Haynes manual). if i run the 2.2 head on the 1.8 block, will i have to do anything with the engine management and such (e.g. finally purchaseing an SAFC ), or will the 1.8 computer figure things out? on a stock bottom end, how much boost am i looking at (ill prolly findout in a bit searching Subachad's posts)
