SSSunny, when head goes on, make sure you get a tune. I can't stress this enough. There is no ecu for such setup, though your gsr ecu will work and the car will drive, you are risking blowing the motor if you start beating on the car.

Yea man, i have put the ls-vtec on hold for now and decided to go boost LS for now, maybe next summer i`ll put the vtec head on top.
next paycheck gona start getting some parts

MPR

SSSunny, when you get your project on the go, make a new build thread and post up some pics!

SSSunny

Will do, when i get time.
How far is your build MP ?

sweet build mpr, good luck with it, can't wait to see the final results!!

MPR

Thanks.

Just cleaning everything up right now. It's all fully disassembled. I'll take some more pics and post them up soon. Bearings had normal wear on them, nothing major.

Next step is to give the cylinders a quick hone, resurface the block and find a vtec head, and start collecting the new bearings, and hardware for reassembly.

Some good news: I've got a turbo!

Tim bought another turbo for the MR2, so I'm going to be using the one that's on it now. It's a freshly rebuilt 60trim T3 from a mid 80's 300zx (single) turbo. It's proven to be too big for the MR2 for autocross. By the time it spools and explodes with power, you have to slam on the brakes for the next gate...lol. So Tim has bought an oem turbo from an impreza WRX. Don't know the specs off the top of my head, but looking at the compressor maps, it'll give us 25psi at 2500-3000rpm!!!!! hehe, can't wait.

The t3 60 trim should be a bit better match for the slighty larger and more freely breathing 1.8L LS-vtec....

25psi @ 2500-3000rpm sounds insane!!!!!!! so when are you picking up the vtec head... i might know somebody who's got a few sir/gsr heads up for sale let me know!!

MPR

Definitely on the lookout for a good deal on a vtec head... Let me know. Send me a PM or txt as soon as you find out!!!

D.T.P

25psi at such low rpm? Will it keep boost up to higher rpm on the straights? That seems quite intense.

MPR

Yeah, it's a very well-rounded turbo. It spools and makes boost quick, but because the MR2 is only a 1.6L, it can still provide enough volume at higher rpm. I believe the most it would do is 20-25psi at around 7000rpm. It can deliever even more boost through the mid-range... but the motor with 200,000kms on it may not agree...haha

^i'm liking the new sig^ btw text me what condition/price range you're looking for because i think there are a couple cheap beat up ones and a few good condition ones but a bit much....

**More pics coming soon!**

Just picked up a B16A2 complete head last night... Needs some cleaning up and will be installing new valve seals/guides. Otherwise, it's good and the price was right.

Total cost to date: $340 for LS motor and B16 head.

Now comes the fun part... gotta get the new bearings, rod, main and head bolts/hardware, gaskets, do the ls-vtec conversion modifications, get new b16 or gsr timing belt/water pump, cam seals, clean everything up and put it together.

Sounds so simple...lol.

D.T.P

We should try to get group by for bearings from honda

MPR

^Good idea! and piston rings and head gaskets and end seals and water pumps and timing belts...shall I go on?

hehe...need LOTS o parts!

MPR

Alrighty, here are some more pics.

First, the fully dis-assembled block/bottom end and all the guts:







And here's the B16A2 head I just picked up. As I was taking a closer look at it I noticed it has already been drilled/tapped/plugged and fitted for an LS Vtec conversion! BONUS!





The head is complete. The rest of the parts I have set aside.


Now this is a dizzy the guy threw into the deal. Problem is, it's not from a b16 and I don't even need a dizzy as I'll be reusing the one on my current b16 engine. Can anyone tell me what engine this dizzy is for???





Thanks for looking.


I plan on fully dis-assembling the head and putting in new valve seals/guides and cleaning everything up, and also throwing some lapping compound on the valves.


More to come soon...

MPR

So things have changed a bit... Aquired a b20 block recently.

May build a B20-VTEC and keep it NA instead of the LS-VTEC turbo setup I was originally going for... Will still make lots of jam and be more reliable for daily driving.

Keep y'all posted.

D.T.P

Good to hear you're build is still going on. B20 is a good choice.
Btw regarding that distributor, its obd2, all I know. May be willing to take it off your hands. We'll see.

MPR

^dizzy already went to someone else... sorry. And it was for a d-series.

Yeah, the build is still going, but not sure what direction at this point...lol.

How is your build going?

D.T.P

Pita, as you know the insurance is biting me hard and other stupid expenses. Engine is back from gord bush. Just need to order bearings/rings/water pump/t-belt. Then save for a tune. Ill upload some pics soon.

MPR

Well... sounds like you're on your way... can't wait to see it when it's done.

I know all too well about all the set-backs... it sucks, but sometimes, that's the way the cookie crumbles...lol
