- Tue Dec 16, 2008 4:51 pm #84006 im about to make an ls vtec b18b1 74xxxx miles on it an gsr heads dont know how many miles buti heard of engines blowing up an all kinds well im having mine done by pros from king motorsport let me know what u think[/b]

- Mon Dec 22, 2008 7:34 pm #85016 LS/VTEC's and CR/VTEC's can be very reliable as long as you build them properly.

I'm preparing for a CR/VTEC build myself. keep in mind that it's a good
idea to have it tuned for maximum reliability.

just a question... why not do the swap yourself and save some cash?

With a lil info digging you can find the right way to do this set up.

Also gives you the opportunity to learn.

- Tue Dec 23, 2008 4:52 am #85097 I even have a post on this forum about building a reliable LS/Vtec motor. You should check it out.

- Tue Dec 23, 2008 6:55 am #85105 may I suggest you rethink using a gsr head and consider using a b16 head

- Tue Dec 23, 2008 12:42 pm #85117 What makes you say that?

From my knowledge gsr heads flow better.

- Tue Dec 23, 2008 4:59 pm #85133 correct me if I'm wrong but I'm pretty sure the b16 head flows better, also the b16 head and type r head are the same minusthe type r having a mild port and polish and different cams

- Tue Dec 23, 2008 5:28 pm #85144 Either can flow better. There are also more differences between the B16a casting and the ITR casting of the PR3 heads. Yes, you covered the Mild hand porting, Dont forget the valve springs or intake valves.

The main reason i was asking why you said go for the b16a head, was because the chamber in the GSR head is smaller than a B16a. Which will raise the compression of the motor more. if he is still using the stock bottom end, it would be benificial for him to use the GSR to get a slight bump in compression. 10.1:1 as opposed to 9.99:1 not a big difference, but you can still add in a thinner head gasket.

I'm thinking about doing the frankenstein LSV. I need some honest opinions on the thing.. reliability, boostability, etc. I've done some reading and im getting alot of mixed reviews.. some places you read its a great motor and others think its trash. I don't want comparisons, suggestions on a different motor or things like that, just some straight talk about an LSV.

I know a couple guys running them, and one guy is making 500 wheel horse with one that is as nearly a daily driver as you can have without it actually being your primary car.. he drives it often, and has for a couple years.

Now for what I was thinking. My LS block and a JDM b16a head. probably stay with stock internals (pistons and rods) but have everything completely torn, cleaned, and rebuilt at a machine shop. Have all moving parts replaced ie bearings, water pump, oil pump, etc. with OEM products except bearings would be ACL bearings and all studs and bolts from ARP.

So thats the idea, LS block, stock rods and pistons, ARP bolts and studs, new bearings, and the head. Then have it professionally put back together. Then I would like to slam between 7 and 12 pounds of boost at it along with a really good tune.

Now its your turn - thoughts? good idea or bad? too much work? a ticking time bomb?

thanks guys n gals.

- Thu Dec 25, 2008 2:09 am #85325 I stay true to the ls/v.
I aby by them. Best motor I've ever had.

- Thu Dec 25, 2008 3:22 am #85336 The motor is a great motor. WHEN BUILT RIGHT. Thats all there is too it.

7 to 12 pounds on stock internals at the compression you will be at is not a good thing. I dont think it would last very long.

You have a good plan, just need better insides.

- Thu Dec 25, 2008 4:24 am #85359 i was gonna go with a much larger headgasket to drop compression down to low 9's or high 8's too, sorry forgot to mention that. I really enjoy low low compression lol
