Hey guys. I have a question for all of you all motor experts. I am thinking about re-doing my del sol this summer and I am debating which would be a better motor for my daily (hopefully soon to be weekend car). I right now have a stock bottom end B20 with a Stock B16 head (with gsr cams) in it now. It is matted to a B16 non-lsd trans. And I LOVE IT. Its quick and got tons of tq which I really like. Now what I am thinking of doing is one of the two following.

A- Doing pistons and a Type-r Head on what I already have now.

or

B- Doing just a full Type-r Swap. Trans and all.

I figured the full swap will cost more but I could always sell my b20 to make up for the extra cost.

So I was wondering what would you guys suggest knowing what I like about my swap and what you have experience with? Now I have driven a Type-r del sol and while I did like it, I just felt that it wasnt as fast although our time slips were about the same him being .2 of a sec lower then me.

So any input would help guys thanks.

 

option a = the same thing you have now with a tad bit of a ported head, you will see next to no difference.

option b= = waste of money because you will be slower with your new hype-r motor.

the correct option is get the head ported, get a decent set of cams, and tune it, and i bet youll **** your pants with the gains you make since you are using maybe half the potential your current setup has.

if you want to take it a step further, replace the factory b20 pistons with a set of RS machines p73 casts, along with porting the head, and cams, and then once you have a 220+whp dyno slip wonder why oyu ever even considered a hype r motor.

 

Yeah why waist money/time swapping on a head that has a nice factory valve job + mild pnp when you could take your Pr3 and get equal or greater work done + better cams.

Like KP mentioned,if it were mine I'd swap in some RS machine ITR's along with getting the head ported with your cam of choice after examining your power goals & driving characteristics you want.

 

OP, you should replace the pistons and rods with forged components. Even if you leave the head stock, you will still make some very good power.

 

for simple builds, b20v is the way to go. just look at the stock sleeve b20 thread.

 

i've tested this. a guy with the exact same engine you have and i raced. the b20v even with the gsr cams is slightly faster than my ITR. with cams that b20v would be even faster. there is no debate on which way to go in my book. the b20v is the faster platform.

 

No replacement for displacement!

 

If it were up to me, I would get an ITR complete. Of course it would be more expensive but that's a type R... imagine the reliability and stock factory power of that thing. If its your daily, the reliability should be some what of a concern. If its a weekend car, then I guess b20v is better choice since it wont cost an arm or a leg. Of course only my opinion

 

Thanks for the input guys. Def going to start looking around for some nice cams and pistons set ups. As well as a machine shop to get everything ready. I through some numbers together and figured that it would cost me around 1k do build the block right (not including machine work). So even with a full head job you are right it would be a lot cheaper to build what I have. Thanks again.

 

yeah im planning on doin my b20v build soon also. but mine is goin in slightly heavier car (in a DA) and i cant waite to see wat numbers i put down

 

IMO you should stay with cast pistons for a daily if you get any because of the knocking due to forged ones

 

b20v builds are alil stronger than itr due to displacement which yields more torque. really depends on what you wanna do and how deep your pockets are. if you're looking for power then b20v is the way to go, but if looking for good reliable power than the itr is also great.

 

There is a lot of mis-information in this thread.

1) a correctly built B20 is very reliable.

2) a correclty built B20v is a lot more powerful than a ITR.

3) you can use forged pistons for a DD. Think CP

 

i dunno about you guys but if a cop out here in cali sees a b20 in your car they ref the living **** outta u. so id prefer the "hype r"..... you wont beat its reliability. or if your del sol is a si just find a b16 block and build the crap outta it...

 

oooo a hype r. do you know the history of a swap you bought? im guessing if he bought a c5 changeover it would be beat to hell...doesnt sound as realiable as a fresh b20 block does it. a friend of mine went through to c5 changeovers from h motors in a year, one dropped a valve and one through a rod out the block...waste of about $8k if you ask me.

it couldnt have anything to do with the turbo guys (the more frequent users of forged pistons) running looser piston to wall clearance to allow for the higher heat expansion they see would it? and whys it bad?

 

be the man.....go pistons and rods on your B20. Port your head with the GSR cams, you will walk Type R's all day!

 

Precisely why I didn't want to invest in a swap vs rebuilding my LS into a frankenstein. I mean at this point the newest B18C5 swap is going to be what? 8 years old, or older with no certainty of mileage and abuse?

Na..... I'd rather build/rebuild a fresh motor anyday for the same cost.

 

Good thing he doesn't live in a GHEY-*** state like CA! Jesus...that place is HELL for Car enthusiasts!

You guys are forgetting ONE THING that he'd get GREAT benefit out of! He already has a B16 trans with some good gearing. I know it's a bit off topic....but Bro, you need an LSD! Think MFactory! No mo peg-legging launches with that increased torque.

I'm of the opinion that JUST THAT ADDITION will likely satisfy you for a bit. I've heard GOBS of people say that that one mod TOTALLY changed their car!

On the engine topic.....B20VTEC, all the way!

 

This is your answer.... doesn't get any more clear than this

 

im getting excited for my build cant waite hehe

 

If u want fats u know what ur getting ur self into.like swaps I live in the OC I have a b16a am going b20V with some type R pistions
**** it if I get state raf..
Lol
B20Vtec live on
