Nice DIY fab work!

Turbo Turtle 07-05-2014 06:48 PM

Thanks.

Turbo lasted two days on 12psi. comp wheel dug into housing. Little to much play lol. So next week I'll be getting a hx35 from a buddy and changing the kit up till that fits

i will be getting my hx35 next week but in the mean time i went ahead and installed an ebay turbo i keep in my garage for mock up when building stuff. its a ching chong gt3582r

since the inlet on the 35r and the hx35 are both 4" im going to go ahead and install my z06 intake that i had for the future v8 swap and connect that to the turbo. havent seen it done so it should be fun

I have thought about this intake for quite a while and wondered why nobody has tried this.
I will be watching this very closely - though those intakes are not easily available here in Germany...

Thanks for the update - interested to see how you manage to connect the intake to the turbo.

BTW - do you happen to have a part.nr. for that intake?

no the intake was given to me. installed an aftermarket intake on a z06 and the guy didnt want the stock one.

i got most of the intake install done today. only a little clearance issue. i think the stock radiator is not going to work with the intake. it is touching the top of the radiator and hits the hood. since ive only ever seen it installed with the aluminum flat top v8 radiators im going to email flyin miata and see what they have to say.

the routing to the turbo will be easy. two 90's and some straight pipe.

are you going to have to remove the bumper to clean/ change the air filter?

Turbo Turtle 07-09-2014 07:36 PM

mmm maybe but i dont think so. but its not my DD so im not to worried about that

Looks like a stock intake from a C5 Corvette to me. But I may be wrong.
In Germany the only way to obtain one may be to visit a certain area in Hamburg and steal it from one of the pimps' cars....

Really nice looking fab work on the hotparts.

Please do share your boost RPM when you get it, it's comical with the turbo that size lol!

Turbo Turtle 07-12-2014 12:48 PM

Thanks!

I may not end up running it with the gt35 since the intake is hitting the hood and I'm getting the hx35 next week any way and I'm out of time to work on it this week. I will share the hx's boost time for sure though. My friend said he had 13psi by about 4k with his low comp 1.6 mr2. I figure 12 should be 3700 or 3500 on the bp

i managed to get the intake to fit under the hood with the stock radiator. cutting the upper core support and cutting the fan mounts off the top of the radiator made it fit just low enough.

made the intake out of aluminized and pie cuts bc its what i had laying around. the coupler is blue bc i had it in my attic and didnt have to buy it. i plan to get a black one soon enough

i welded some 8an fittings on the valve cover and drilled out all the passages in the cover to get the engine breathing a little better

until now i just had a small filter stuck on the iac. i got to thinking about it and wasnt confident that it would be holding boost back or becoming a boost leak at wot. so i redid that and now its pulling from the charge piping.

the hood pins are nice but man they are nerve wrecking to install lol

i have all the fittings and flanges ready to install the hx35 now i just have to find time since i have to cut the manifold, dp, and run the water lines

i have been running the cheap ebay journal bearing gt3582r knock off for a couple weeks. i actually surprised with the spool up and im no longer worried about the hx spooling to slow. the gt35 will hit 12psi by 3700 in 2nd but only at wot. the small turbo would spool at part throttle so thats disappointing. the gt will only spool if you push it hard. the small turbo was fun around town with out pushing but not the gt35. how ever merging onto the interstate the gt will absolutely fly. im hoping the hx will be in between

Volkswagen used to do a special edition model of the Polo in the 80s called Polo Harlekin

engine rebuild and coolant reroute
 
3 Attachment(s)
i decided to rebuild the engine before i installed the hx35 because it is using about a gallon of oil between oil changes. compression is perfect but valve stem seals are shot and oil control rings also seem to be stuck.

im going to putting some H beam rods in with stock pistons while i have it apart. also putting some arp hardware in the mix and acl race bearings.

ive spent the last week working on the head. the carbon on the valves was horrible and the lifters were all smacking and knocking. most of the lifters had converted themselves to solid buckets without asking for permission. they are nice and squishy now.

i figured since im building the engine and putting this much work in i should go ahead with a coolant reroute. after doing a lot of reading on the process that most use i decided not to do what every one else does. i did not buy the ridiculously over priced spacer. i have had a bp festiva that i swapped before i bought my miata and i know the bp can run just fine with out a spacer. so i just made my own reroute. the only problem being you can not use the stock coil packs with it. which i dont see why most people worry about b/c most are running cop any way.

every one on here knows what a rebuilt engine and head work looks like so ill just show some pics of the coolant reroute.

im using the miata thermostat housing moved to the back. made a plate to block off the front port. welded on a piece of pipe for the heater in the same location as a escort bp just facing the other way. it connects to stock heater core line. also using stock upper radiator hose on the back as well. puts the exit right at the back of the intake manifold. i'll finish the rest of the reroute once i get the short block finished

i static balanced the rotating assembly

rods

These are a set of eBay forged connecting rods. They are from crankshaft depot. They come with arp hardware but give no solid guarantee on balance.

After measuring weight and bore I believe these are unlabeled Eagle rods. The balance and weight was within Eagle spec. I would not be surprised if they were made in the same factory.

The balance was much closer than factory spec and matched Eagle but I balanced them to perfection. Both small end and total weight were balanced. I left the bearings and hardware in for this process

I have never use a set of these rods bc I refused to use cheap stuff on a customers car. But since this is my car and I have a low power goal of 300whp with stock pistons I figured I would try them

pistons

I have a list of before and after specs on this. one of the weights with wrist pins and clips and the other is with out. Since the piston was the cause of the difference I could not simply switch pins around. All weights were set to match the lightest piston.

The castings were cleaned to reduce weight but most weight was taken out of the wrist pin since very little steel must be removed compared to aluminum. They are perfectly matched now and each wish pin must stay with its piston now.

i got the long block assembled with a new nb vvt style oil pump and timing gear from rosenthal.

started working on the water lines for the turbo. i know most people use the oil cooler lines but the stock lines on the hx35 were way larger than that and i wanted it to have all the water it was designed for so i redid that water outlet that goes to the header to run a 8an line to the turbo. the heater core will feed the turbo from the other side.

its a little close to the manifold so i'll make a small heat shield and get some wrap for the line

i made a change to my thermostat housing. it seemed a little to high like it may cavitate.

https://www.miataturbo.net/attachmen...ine=1414125393

clearance on the turbo water feed/heater line. couldnt be any closer to the power steering pump if i would have measured lol

https://www.miataturbo.net/attachmen...ine=1414125393

i got the engine installed and built the rest of the cooling system

a few to many hose clamps on the heater line for my taste but it will work

Drove the car today. I'm very impressed with the hx35 so far.

Just a few things left to install on the car before it's ready for more boost. Building a breather tank. Need to install the boost control solenoid, ls cops, and 190 fuel pump.

Hope my transmission does ok with 20psi

been a while since ive posted any updates. i havent changed a lot, just boost playing with the tune and turning boost up.

to start with i installed my ebc solenoid
Attachment 184441

seemed to be spooling slower and slower. so i found that the turn buckle i used did not hold tight i guess bc of heat. it was open this much...
https://www.miataturbo.net/attachmen...ine=1422680619

so i fixed that
http://i989.photobucket.com/albums/a...pselixmt79.jpg

cut all the iwg brackets off the exhaust housing
Attachment 184442

painted and re-installed.
https://www.miataturbo.net/attachmen...ine=1422680619

https://www.miataturbo.net/attachmen...ine=1422680619

has any one else ran this turbo on the miata? i was expected pretty slow spool up bc of its size. but im seeing 240kpa at 3100rpm on my data log and this thing is an absolute monster on the street. it is spooling as fast as the tiny to4b with a .48 t3 exhaust housing but making a lot more power.

and just for a fun a pic of the car
