Thread: what blocks?

alright i have a gti-r with a bad block/head (bought it that way) now im trying to build a motor but i cant seem to find a gti-r block. what other blocks can i use? any fwd block? i know the rwd ones wont work 53j? some1 please shed some light, i've been trying to figured it out for a while and just came seem to find a post anywhere that says what blocks/heads will work!

any sr20fwd block

you wouldn't happen to know the different casting numbers would you? i saw it the other day and cant seem to track it down again, thanks for the info!

no blocks are different,

all sr20 blocks are different! all will have to be customed to fit.

The GTi-R block has thicker head bolts and a wider (EDIT: more narrow!) oil pan configuration. It's not going to be a simple thing to do. I'd ditch the entire idea and start over with a good engine. I mean, what's wrong with the GTi-R block and head exactly?

the guy spun 3 mains and 3 rods. i turned the car to the on position and the greddy profec was at 100% (35 pounds) which explains why i have a t28 with a brand new rebuild on it aswell. i just purchaced a fwd block and i'll be going with the same head. the motor im putting in is completely built anyways so i just dont see why it matters if the GTi-R has thicker rod bearings and stuff. its all top of the line as is.

If you use another FWD block with a GTi-R head you will need to, and correct me if I am wrong, have the dowel holes and head bolt holes on the block enlarged to fit the GTi-R studs and dowels. Now, that said it was done on one of the forums and the guy didn't enlarge the head bolt holes and just used the standard bolts. There was talk about fear of head float, but he wasn't running big numbers at all and had no real worries. I don't recall reading about it going bad so who knows how that ended.

Keep in mind that if you get a non-turbo FWD block you will need to get it preped for that turbo setup as well.

Things you lose in going with a non-GTi-R block: oild cooler, beefier crank and rod bearings, larger flywheel bolts, heartier oil pump, better head bolts. The GTi-R is a narrow block engine, so you could move up to a wide block... but really there isn't anything special about that.

R stuff isn't hard to find, you just got to be willing to spend the money for it. If you just went "what ever" to that comment then you should just get yourself a normal SR and not the harder to attend to R. Yea, the R head breaths better then the other DEs, but at this point you just as well go VE if your going to jump through all these hoops, and sell the R head to someone with an R that wants a back-up.

Just my 2 cents from knowing a guy with a GTi-R engine.

the head is trashed its already been to a machine shop and the guy that owned it before and blew it up did a NUMBER on that motor. im going all new and all aftermarket, im going for big power so im just using another SR block. all the internals are switch, oil pump and water will be new, im using a 10 row oil cooler in the stock top mount spot. i was just wondering if i could bolt in/up to tranny the other sr motors, internals are FAR from stock, as with head, it will be COMPLETELY built. i didn't sell my GTR to cheap out, im just going for ridiculous power

All FWD SR trannies will bolt up to all other FWD/AWD SR blocks.

As for visa versa, AWD tranny to any FWD block, not so much if you want them to work. You will need a narrow block SR (i.e. an AWD block). The narrow blocks are built to let the drivetrain stuff all fit down there.
