Hi, i have a 94 integra B18B1. I want to do a ls/vtec conversion to it. ive done research and know what i want.......a fast racing/daily driver(upgraded internals-- N/A....no forced induction). ive been looking at heads and i found a type r head (belongs to a local i know) its straight from japan and still in the boxes...unassembled and its complete(plus ported and polished by honda factory)! i havent bought it yet, but im going to get it for $500-$600!.. this is an excellent deal....anyways....as far as upgrading the internals....do i need to upgrade the CTR camshafts or the springs, etc.? since everything is new and type r ......r titanium springs and such necessary as far as boosting hp? also is a ls/vtec conversion w/ a type r head and a ls block(longest stroke block-b series) a good combo....i think it would be the best combo possible-long block and powerful head=low end and high end. correct me if im mistaking! also would it matter if i put the brand new head on my 170mile block?-----considering that future mods will be done to the block. .......i have plenty of other questions that are worth answering so i highly appreciate the answers!!!!!!!!-thanks

Run some searches in this forum and the Let's get technical forum. You will instantly get all the information you can stand to read. Then come back and ask some more narrowed down specific questions.Also I hate to break it to you but the head that you are talking about getting is NOT going to be ported and polished from Honda. If it is even an ITR head it will be stock and the same as every other ITR head, the only thing different between the USDM and JDM ITR heads are the cams. The guy is trying to rip you off most likely, I am not trying to sound negative but I would be very cautious in that deal.

HUH.......this is what he said "Description-

This Complete Genuine JDM Integra Type R Cylinder Head has been ordered directly from Honda of Japan. The Type R Cylinder Head is unique because it comes from the Honda factory ported and polished and it has a fantastic valve job designed to optimize air flow.
items included: -JDM Bare Type R Cylinder Head w/ Cam Caps & Cam Rails -JDM Civic Type R Intake & Exhaust Camshafts -JDM VTEC Solenoid -Type R Lost Motion Assemblies -Type R Rocker Arms, Misc Bolts, Seals Etc -Type R Yellow Intake Inner & Outer Valve Springs & Retainers -Type R Blue Exhaust Inner & Outer Valve Springs & Retainers -Type R Lightweight Valves w/ Keepers -Type R Red Valve Cover

I purchased the head in order to mate it to a built block, but decided to go in another direction. All the components of the head are untouched and still in original HONDA JAPAN packaging."...........

so ur saying this cant be possible?...thats interesting......let me know what u think of this head description....and after reading a lot of the ls/vtec conversations here and at hybrid garage, people seem to say that JRSC is the way to go for boost and it will work the N/A ls/vtec mods.....let me know.....and i highly appreciate ur quick response!-THANKS

The ITR head does have a mild port and polish stock. It's nothing crazy, but they did P&P it. Also I hope you know that you're not going to be able to rev the motor like crazy or anything. You can only safely rev it as high as the LS bottom end will allow. Just in case you didn't know. I've known a few people who have done the LS/VTEC and reved the crap out of the motor, and then they were surprised when they threw a rod.

huh....so what if i get new racing rods and type r pistons and maybe a lil borin....would that prevent me from doing what everyone else seems to be doing(blowing the engine)?......i mean .....im not completely clueless abbout this stuff, its just the ls/vtec that makes me wonder.-THANKS

Yea they port and polished it a little but like I said it is not anything special, just the same as any other ITR head. The guy seems to be trying to market it as an ITR head that has been port and polished, that is why I told him that. I should have been clearer I suppose.As for the revving topic, you are going to want to stay under 8K rpm. The B18C5 has an R/S of 1.58 and your B18B1 has an R/S of 1.54 not a tremendous difference but enough to cause problems when reved too high. If you are going to build the LS/VTEC then get a block girdle, this will tie all the main bearing caps together and make them more rigid and stronger. Boring your motor or replacing your rods is not going to do anything to increase the rev capability of your motor. The only thing that can increase the safe rev capability is a better R/S. You clearly need to do a little more research about the LS/VTEC, I know that almost every LS/VTEC thread has something about R/S or rev capabilities.

yea a buddy of mine(family mechanic) was telling me about a block girdle..........personally and due to the facts u know, would u say a ls/vtec or a JRSC........an ls/vtec is cheaper too right....i dont know.....i just like the fact of a N/A built engineand fast but everyone seems to say......naw put a turb or s. charger on an LS..........also what about doing the ls/vtec w/ the type r head and then putting in an jrsc or turbo? or is it a bad idea due to the high compression of the type r head?

the head has dothing to do with compression ratio, that has to do with the block as well. I've been planning on a ls/vtec w/turbo, but i'm still doing my research for useing high boost, but you could use 7lbs of bost safley on stock internals.

i have a question is it possible to swap a RB25DET engine in a 95 integra?

i have a question is it possible to swap a RB25DET engine in a 95 integra?Anything is possible if you have a ton of $ and know a lot about cars. If you know how to make a FWD car into a RWD car then you've got a chance. Otherwise you'll be paying someone a ton of $ to do it, and when you're done (if it runs and drives correctly) the car will being worth less than the $ you put into it. My advise (and pretty much everyone will agree) is to stick with the regular Honda/Acura swaps. If you've got the loot to try something less "average" swap in a K-series motor.

Lime green: I strongly suggest sitting down and thinking about this before you make any buying actions. I hate to sound negative, or even imply so, but I have a b20vtec N/A and building another, and it took me some special time to read to know exactly what I want. I made the mistake of doing this and that...hence why I screwed myself in a way and wanting to build another motor. Why not get aftermarket pistons, like JE or Wiseco 11.5+ if you want N/A? As for the final record on the stock internals + boost. I have a friend run stock internals with 6lbs for 8 months and his car is still find.

You can swap in a SR20DET, but not worth the time and money. There's someone on my Team Sol forum who swapped one in his Del Sol, but it's taken him three years, a lot of money, and a lot of headaches. I agee with CivicSpoon that you're better off sticking with Honda family motor swaps.

You have a lot of options available to you with Honda motors and are better off staying that route.

yeah, i got a complete GSR head, its fully built....milled ported and polished...skunk2 valves and springs, etc.!!!!------700.00$ yeah so im hyped. im going to do the ls/vtec conversion and then turbo or supercharge it.....which one would be best?

whtteg has already told you to SEARCH, and you need to...which F/I you choose is based on how you want your car to perform. do some searches to deside which boost you want.

Thanks for the info. what about a B18C5 motor or perhaps a K20A. will both of these work?

of course, you'll just have to do some wiring for the OBD conversion. This: http://www.honda-tech.com/zerothread?id=550976 and a OBD1 to OBD2 conversion harness will work. Or you could get a rechipped d16z6 ecu (p28) and it will be OBD1 (same as your car) and you won't need to wire for the knock sensor. EDIT: I ment with the p28 ECU you wouldn't need the conversion harness, you'd still need to do the wiring in that link I gave.

A K20A will work, it will be more expensive and need some fabrication. Do a google search and you'll find a few walkthroughs on this swap.
