alright guys I'm being indecisive so I need ur help. I know I'm going to swap and turbo but I cant decide which to do first. I'm going to be swapping in a ITR engine and I'm going to run 8 psi on the turbo. So now it comes down to which I should do first. So if u guys could help me by choosing for me that would be great. hahafeel free to give pros and cons of doing one before the other and thanks in advanced for the help.

 

I'd say swap first, then set up your turbo setup to run on the new motor, makes the most sense to me

 

I wouldn't boost a ITR. The compression on the motor is high from the factory

True, but there are plenty of boosted ITR's running around.

Hell ya Crazy fast too lol But they use different pistons to drop compression I know some one who has a ITR and took the Motor out for a GSR I almost cried lol but its all good I have the motor now

 

so how would i lower the compression and would it still be reliable? also if not the ITR swap what would you suggest. i would keep my b16 but its my DD so it has high milage and when i do the swap its not going to be my DD anymore

 

i think you can use a thicker HG to lower compression a little bit (unsure abut that though) - but it would be a waste to turbo a motor, get your ecu tuned, and everything else you need to do. then, later on swap a new motor in and have to do it all over. are you going from D to B? thats also a factor where i dont think a D series turbo manifold will bolt onto a B series motor.

 

Head Gaskets work but i dont like to use them a lot, Piston change would lower compression on the motor

 

probot in regards to your post-

the car comes stock with the USDM b16 so its the b16a2 rated at 160 HP and its got like 120,000 miles on it right now. so i figured swapping in the ITR would give me a 20+ whp gain right off the bat and then turbo it to get more power, but no one ever told me that turboing the ITR could be bad cause of the compression. if i dont do the ITR swap then what would be a good one to do please dont say K series cause i dont have the money for that haha.

For boost H22 there strong for boost and one thing your right Ks are too much and my self thinks there a waste of money

 

Have you factored the cost of getting the ITR motor against the cost of rebuilding your B16a2? How much can you sell your B16a2 w/ 120k in your area for? How much are the ITR motors in your area? Ever thought about a B18c (P72)?

 

in regards to projectEJ1's comment, no i havnt cause i have no clue what i would need to rebuild the b16, if youd like to help me out with a link or something that has a list of everything i would need then i could do that. also i have no clue i would have to test the waters cause i havent seen any posts for a b16 with anywhere close to my milage on them. itr motors in my area between 3000-4000 depending on if its a complete swap and how many miles are on the motor/tranny. no i havnt thought of b18c if your refering to the GSR motor. i thought they only had a HP rating of 185 so i thought for the money i would pay it wouldnt be worth it but then again i dont know how much a GSR motor is either. feel free to enlighten me on all this stuff haha cause the more i learn the better

 

A rebuild may cost a little more, but you will have a fresh motor with 0 miles. You usually have the block checked and a possible light hone and check the deck for level. Replace the pistons or perhaps just the rings. New bearings and gaskets all the way around. Check the head for level and replace the valve seals and gaskets.

As for motor pricing (Longblocks) you can check http://www.hmotorsonline.com . IMO if I were in your shoes and looking to get another motor I would definitely get the B18c (GSR/P72). Its cheaper and yes it may have less hp, but the difference isnt going to really matter much once you turbo it. Either way that EM1 is going to move.

EDIT: Here is a copy/paste from Hmotors

There's always another option. For example, take the money you would spend on another motor and use it for a GSR block and forged internals. Mate your head to it, and you have a PoorMan's Type R. It's what I'm doing with my car.

This is a common practice with ITR motors. However, there are many stock internal boosted ITRs running well.

 

Roughly how much would it cost to do forged internals on a gsr motor?

"edit" what are the pros and cons of a poor mans type r VS a straight up GSR motor

 

It cost me $875 for Wiseco Pistons/ Eagle Rods/ACL Bearings right here on H-T.

Pros and Cons, you'd have to look up yourself, the arguements are ongoing and many.

Pros of Real Type Wah. = Honda Assembled It
Cons of Poor Man = You Assembled It

Search around Forced Induction forums and at HT sponsors...They have prices..

 

bump anyone else have an opinion about poor mans type r vs straight up gsr??

 

You should do the gsr swap then do type r pistons... go NA and then just build the motor. and get itr cams. a few adjustments to a gsr and you would pretty much have a motor that could be faster than a itr stock.

 

dude you just brought up a thread that is almost a month old.

 

Just rebuild the B16...honestly, it'd be stupid not too.

Let's say you get the ITR and you turbo it on the stock internals...it's a roll of the dice as to how long it's going to last (although a majority depends on the tune). Let's say you turned around and invested that money in rebuilding your B16 (forged low comp. pistons, forged rods, ARP headstuds, rebuilt head, aka the works)...not only would you have a motor that can take a hell of alot more abuse, but will have the potential to make more power in the long run.




And I just saw that this thread is pretty old, but I figure that I typed some decent information and maybe somebody will read it and possibly use it.
