I am just going to run low boost. . . yea right!, A warning for anyone who wants to boost a 5sfe Options

Now that I am switched over to a water to air intercooler I decided to build a cold air intake to battle intercooler heat soak. I noticed that when I am at idle for a long time with the intercooler fan off that the intercooler water temps will climb from mid 90s to 110+. I did not feel like paying $200 or more for some company's cold intake set up so I built my own. I had some extra couplers laying around, some 3 inch intercooler pipe, and kept the existing cone filter.

And here is a shot with the water guard on the filter. I can't have my 3s getting hydro-locked.

To me it's silly to spend what it costs on a big name brand kit, especially whens gains are usually negligible. Just make your own since piping is piping and couplers are couplers, then top it off with a name brand filter.

$200-300 for and advertised 5-10 hp gain is not worth it. I built this one for about $50.

Exactly. I think it cost me like $70 for piping, couplers, and an AEM filter vs almost $300 for a K&N or SLP cold air intake. Yeah it took some more fiddling with I'm sure, but worth saving $200+ for probably the exact same end result.

I was able to find another CT15B for my 4th gen 3sgte. I was looking for one so I could get it rebuilt and upgraded without taking the car down for a few weeks during track season. I just got it in today.



I am planning to send it off to ATS Racing to get the "Sweet ct16" done to it. I am pretty excited! At 17 psi both ATS and MR2Prime are advertising around 320 hp to the wheels. It may be more with my stage 1 Brian Crower camshafts.

My concern is the wastegate. The problem with the stock wastegate is that when I get on it the boost will shoot 1-3 psi past the target then settles in at the boost level I am shooting for. There is no way to adjust the OEM wastegate, it is sealed shut, does not have an adjustable actuating arm, and it is welded to the bracket. I am wondering if it is doing that because it is wearing out.


ATS offers a billet adjustable wastegate upgrade for an extra $200. You can chose to have a 12, 14.5, or 17 psi spring put into it. I am wondering if that is the best option because when they mean adjustable does that mean you can adjust the actuating arm or does it mean you can swap springs? Is it a 1 or 2 port wastegate? If I go that route I plan to get the 12 psi one but I am a little uncomfortable with my base pressure being 12 psi. It will make it hard for me to set up boost by gear when I go standalone with that high of a starting boost level. Is there an option to go with a Turbosmart 2 port wastegate? Then I could have a low base pressure and with a 4 port boost controller. Then I can multiply that by up to 4 times and get my boost extremely acurate. Which Turbosmart model would I need? Which bracket would I need for it? I am planning to e-mail a bunch of these questions to ATS but I welcome any of your thoughts.

I got the side skirts installed on the car. It really improves the look.


This thread really helped me to install them.

Too bad Photobucket has messed up the photos.

verts definitely look alot better with sideskirts on. looks great!

Now it needs rear splitters to finish the look.

I have some but they do not fit right with the convertible so I took them off.

You'll have to get ones for the Curren.

What about also having the intercooler fan RPM based so when the engine drops to low speeds near or at idle the fan turns on to prevent heat soak from even starting, in addition to a temperature control.

I am doing a conversion of my front headlights over to LED. These halogen bulbs are not cutting it! They are definitely too dim when compared to a lot of the newer car's headlights. I went with the Auxbeam brand and they look great.


Right now I only have the headlights on LEDs but I am trying to find a good LED that will fit into the fog light housing. The only issue I had with the install is I had to plug the bulb in backwards because the polarity is reversed.

I replaced my bumper that I cut to s**t trying to figure out my engine heat issue. Come to find out it was not air flow but my A2A intercooler heat soaking and blocking air flow to my radiator. I decided to get another bumper that was clean with out any ducts. Check it out:


I made the decision to go back to a stock looking bumper after parking next to a Supra and seeing how clean that car looked next to mine.


Clean Supra vs Ricer Celica

The beam on those LED conversion craps are awful, glare all over, lots of light where you don't need it or want it.

[jordisonjr]

New bumper will look way better.
I was personally never a huge fan of the vents all over the place.

I was ok with the first two on the top, didn't like the lower two. I would say going for more of a sleeper look, but then the hood ruins that vibe.

I am with you. I was fine with just the one duct up top. I got too out of hand with the ducts. Here is a shot of the car with the bumper on.


I got to get a photo ready for Celica of the month.

Woo, much better.

I just went out for a little bit of spirited driving and OH MAN! This engine is crazy! I am only running 7-8 psi (stock wastegate pressure) and the car keeps breaking loose the front tires, especially in turns. I think part of it is the MR2 LSD I have in the S54 tranny because soon as the boost hits 5-7 psi I feel the tires give a little bit. This engine is awesome! I am afraid to turn the boost up to 15 psi where I want it to be. I guess it is time to save for some better tires.

what model MR2 did you find the lsd out of?

It is out of the MR2 Spyder or Lotus. Here is an ebay link for one:
https://www.ebay.com/itm/Toyota-Helical-Lim...q8S&vxp=mtr
It drops right into the S54 transmission. Just make sure you swap the speedo gear from you stock diff. I forgot to do that and my speedometer read the wrong speed. I had a transmission shop do the swap because there are some specialized tools needed for taking the tranny completely apart and putting it back together.
